Shenzhen Riyueguanghua 1000W dual knobs full spectrum led grow lights in production Large and dense cannabis plants mean that you are about to have a good harvest. However, height alone does not mean large production. In fact, it may indicate the opposite. Identifying when cannabis plants stretch and knowing how to respond are the key to achieving good yields. Here's how to deal with weeds and plants that are too high. Is your marijuana plant too tall? For many reasons, elastic, slender plants can be annoying. From falling to self Immolation on your lighting equipment, it is not advisable for plants to grow out of control. A taller plant does not necessarily mean a bigger harvest. In fact, tall cannabis plants may be a sign of their unhappiness, especially because they don't have enough light. Insufficient light will not only lead to plant elongation, but also have a negative impact on the size and quality of the final crop. So, how to prevent weeds and plants from growing too high? There are many options for you to choose from, and some will also help to improve your production! Why did you stop the marijuana plant from growing too high? There are many good reasons to stop marijuana plants from growing too high. Whether to maximize the potential of growth space or to hide growth, you need to ensure that your plants grow unchecked. The following are some of the reasons for controlling the growth of cannabis plants: Privacy and security large plants will attract more attention through size and smell. Flowering stretch some plants can double in size at the beginning of flowering. If you are not prepared for this, you may find that your growth space is not large enough. Plants with equal light distribution will get a lot of light at the crown, but little near the root. This means that the lower buds are difficult to develop and reduce the yield potential. If you are growing more than one variety, some varieties will be smaller than others. Unless you control the height of higher plants, they will prevent smaller plants from getting enough light. Prevent light burns. If your plants grow too high and too close to the light, they will be burned. This could hinder overall growth and destroy the main colas at the top. Why do my marijuana plants grow tall and thin? If your weed plant grows too high, one of the first things to do is to find out why it happens. Otherwise, you may use the wrong solution, which will have a negative impact on your growth. Reasons why weeds may become too high include: Incorrect light distance if your lights are too far from your plants, they will try to get closer. This is an innate behavior that attempts to surpass competitive plant life. Weak light if your light is not strong enough, your plants will stretch upward. No matter how high or low their position is, they will look for light until they are satisfied. In nature, red is the main spectrum, and cannabis plants grow in spring and summer. At these times, when the sun is strongest, plants are affected by the blue and white spectra. In autumn, sunlight weakens and enters the red spectrum. To provide enough light fuel for your plants, make sure you use the correct spectrum at their respective stages of development. You let them grow marijuana under long-term light, and the plants will continue to grow during the plant growth period. So if you feed them for a long time without control, they will become very large and clumsy. Genetics: some varieties of marijuana like to grow tall and thin, such as plush grass. Although these can be controlled, if your height is really limited, many indica rice varieties are more suitable. Vegetative growth period is usually the best period to control plant growth. This is because you can damage it and it will recover before flowering. However, during flowering, damage may only lead to yield reduction. So don't wait for action! Bending or low stress training Low stress training (LST) and bending are good methods to control stretching. In fact, they are just good practice. They can not only keep the plant low from the ground, but also increase the light transmittance to all bud parts, so as to improve the yield. By tying the main stem laterally, one side of the plant becomes the crown. This makes the total surface area exposed to strong light much larger. Therefore, bending can not only control the growth, but also make the bud development of the whole plant larger and more equal. This is a method that is best used from an early age. This is especially good for self flowering plants because they cannot handle high stress techniques well. Watering This is a more active training method. Topping involves cutting off the top of the plant, where the main Cola will begin to grow. By doing so, plants are restored not by planting one, but by planting two new major cola. They tend to grow outward rather than upward. So, again, you not only control the height of the plant, but also get more buds! Just make sure you do this during plant growth, otherwise you will only cut off your main bud! ScrOG The green screen (scrog) method includes planting plants through a mesh screen and binding them. Therefore, instead of growing upward, they begin to grow outward. This technology once again exposes the largest surface area to light. Topping before flower Let your plant grow unaffected during the vegetative growth period, and then watering before flowering can also control the height. When your plant is about to bloom, top all the branches. This has the effect of inhibiting flowering extension; Instead of focusing on stretching, these plants are urged to produce new flowers to grow. Sometimes, pre flower topping requires complete pre flower pruning. If your plant fills the growth space during the vegetative growth period, it is impossible to have enough flowering space. It's time to be bold. Actively trim the plant to half its size and switch the light to the 12 / 12 flowering cycle. Don't worry, marijuana is very cold resistant and can even recover from a stem with only one or two leaves left. Try not to blame yourself for the loss of time and the reduction of the final rate of return. All courses are good courses for becoming a weed Planting Expert. Move tall plants to the edge If it's too late and some of your plants have elongated, you may just want to move them to avoid mild burns. The intensity of light is strongest in the middle, so by moving plants aside, they are unlikely to be charred. In addition, smaller plants get more light, making them less likely to stretch. However, it should be noted that if higher plants have begun to stretch, removing them from the strongest light may exacerbate the problem. This can be done during the vegetative or flowering period. How to control the height of flowering Ideally, you will notice that your cannabis plant is too high during the nutritional period, and then you will take some measures. But life is not always ideal! As mentioned earlier, the size of some strains can be doubled in the early flowering stage, while the change range of other strains is very different. If you have never planted a variety before, you may not know how easy it is to stretch during flowering. Therefore, you may find that your growth space is suddenly flooded and needs to be remedied. Turn the growth light as high as possible At this stage, your choices are limited, and I hope the upward growth will end soon. Therefore, considering this, one of the best choices may be to turn up the light to avoid light burns as much as possible. Plants do not extend until flowering. However, depending on your growth space, this may not be possible. Reduce the daily light time Plants need light to grow (you may know that). Therefore, reducing the light supply of plants will reduce their growth ability. You don't want to reduce too much, because you will only destroy your harvest. However, reducing the daily exercise time to 11 hours or even 10 hours is expected to reduce stretching at this point. Put a lollipop on your plant Lollipop is one of the few flowering training methods. It can not only prevent your plants from growing too high, but also reduce the chance of humidity and mildew, and is expected to increase your yield. Just remember, if you use it to control growth, it must be completed before stretching. Once it happens, it cannot be remedied. To eat lollipops, remove all slow-growing plants. Although you may think all this is precious, the leaves and buds at the bottom have little light, but they still absorb the energy of the plant. In fact, cannabis plants naturally shed lower leaves, which consume more energy than they produce. This is only accelerating the process. Progressive harvest If your plant is too high and burnt, you'd better harvest the buds as soon as possible. Once their hair starts to turn milky white, cut them off. This may not be ideal, but it may be the best choice. By doing so, lower Cola will get more light and is expected to produce higher quality buds. Reduce light intensity If you don't have the option to move the light higher, and your plants have stretched, one of the only options left may be to reduce the light intensity to reduce light burning. If you reach this stage, you may have to accept some reduction in combustion or production. But try to balance power reduction and plant height, and you should be safe. Super cultivation during flowering This is a desperate measure and should be implemented as a last resort. It involves sharply bending the highest branches of the plant during flowering. Your factory will put energy on the recycling part, so it is harmful in general. However, if it develops to this stage, it is about damage control. Most likely, if you leave them open, you'll fire your plants, so don't be upset about the impossible! If you do this early enough, the lower branches and buds will become higher and larger, and are expected to make up for your loss in some way. Too high cannabis plant: learning from mistakes Every growth is a huge learning experience. As long as you notice what's wrong, failure is not harmful. In fact, as long as we pay attention, there will be no failure. With this in mind, how can we prevent the next plant stretch and unnecessary height? Use smaller cans The size of the pot determines the maximum possible size of the plant. The bigger the plant grows, the bigger the root system. Therefore, if your last crop grows too high, reduce the size of the container next time, which will limit their growth. The best thing about this option is that it does not require intervention during growth and does not pose a threat to the health of the plant (as long as the flowerpot is not very small). Keep the growth lights at the best distance. Maintaining the perfect distance between growth lights and crops will prevent them from spreading, especially during plant growth. You want them more or less close and you can get them without the risk of minor burns. Just make sure to move the light higher as the plants grow! Consider the type of light Different types of light provide more or less energy and are divided into different spectra. Using the right light power and spectrum will encourage your plants to grow dense and strong, rather than upward in search of light. Study your variety If you buy a commercial marijuana seed, or you know what kind of marijuana you are growing, there will be information about the average height indoors and outdoors. This will tell you how tall the plant will be if it grows under the best conditions. If the average height of a plant seems to be driving its growth, consider a smaller specimen and give it some leeway under tension. In general, indica rice grows short and dense, while sativa grows tall and slender. Don't wait too long to blossom As mentioned above, the longer you plant a plant, the higher it will grow. So switch it at the right time. If it becomes too big, cover it, let it recover, and then replace it with flowering. When you are still in the vegetative stage, you have a lot of space to play. Since the size of the plant can be doubled at the early flowering stage, please check the maximum height of the series, and then switch to flowering when its size is half of that of the line. It is likely to occur under this expectation, depending on the pressure, but it is unlikely to become greater. Consider growing in a higher growth space This is a luxury that many people don't have at all. However, if your crop has too much space to grow in the last time, consider using more space next time. Having more space can not only make additional stretching, but also help ventilation and make crops healthier. Important precautions for indoor tall cannabis plants When indoor plants grow very tall, there are two things to pay attention to. humidity Marijuana emits a lot of water. Marijuana prefers a relative humidity (RH) of 50 – 65%. When they become too large, humidity becomes a problem because plants constantly release water vapor into the air. Water then accumulates on the leaves and other surfaces of the growth chamber, which may cause mold and other problems. If humidity becomes a problem, dehumidifier or increasing the power of exhaust fan can help solve it. Fallen leaves can also increase airflow to control humidity. Remove only the lower and middle fan blades. This increases the light transmittance of low flowering branches. temperature As with humidity, when plants grow too large, the temperature in the growing area will rise. Reduced airflow and high altitude will lead to increased temperature, making plants too close to light to grow. Cannabis grows vigorously at an average temperature of 25 ° C. Plants stretch more easily when the temperature exceeds 25 ° C. High temperatures also affect the formation of leaves and flowers, as well as the final taste and potency of buds.

RYGH Donated 10,000 RMB for flood disaster in Shanxi Province, China RYGH Donated 10,000 RMB for flood disaster in Shanxi Province, China On October 12, Shanxi Province held a press conference on flood control and disaster relief to report the recent situation of flood control, rescue and disaster relief. It is reported that the heavy rainfall affected 1.7571 million people in 76 counties (cities and districts) of 11 cities in the province, 15 people died and 3 people were missing, 120100 people were urgently relocated, the affected area of crops was 3.5769 million mu, 19500 houses collapsed, 18200 seriously damaged, and the direct economic loss was 5.029 billion yuan. Most areas of Taiyuan, Yangquan, Linfen, Changzhi, Luliang and Jinzhong have set a record of accumulated rainfall in the first ten days of October. In the monthly national precipitation map of the Central Meteorological Observatory, Shanxi is almost buried by crimson. In most areas of Shanxi, the rainfall has exceeded 100 mm, reaching the level of heavy rain. What is this concept? According to meteorology, 1 mm of rainfall is equivalent to pouring about 650 liters of water per mu of land, and 100 mm of rainfall is equivalent to spraying more than 60 tons of water on one mu of land. This rainfall is indeed much less than the maximum rainfall of 907 mm in Henan rainstorm. It seems that it is not enough to threaten Shanxi at all. But in fact, Shanxi has been raining since September, almost without stopping. When the proportion of water absorbed by the land reaches the upper limit, the sudden rainstorm is like the last straw crushed. Shanxi was immediately unable to resist. First, many embankments broke in the reach of the Wuma River, floods spread into villages, destroyed farmland and bungalows, and everywhere they went was a land of peace. In order to avoid the flood, the local United eight villages. Hard life evacuated tens of thousands of villagers to safety overnight. At the same time, a landslide occurred in Jingpo village, Pu county. Five traffic policemen had no time to avoid being buried in the soil. Finally, four people died on duty. In some places, the mountain sediment directly annihilated the whole building. The ground collapsed in some parking lots. After the car fell into a deep pit, the big pit was soon filled into a small pond by the flood. Moreover, the rainstorm also washed away the foundations of many buildings and bridges. The abutment of Changyuan River Bridge was washed away and the railway tracks were directly suspended. Some revetments along the river finally collapsed into the river bottom due to continuous scouring. Under the rainstorm, the No. 84 inner wall of Pingyao ancient city, a national key cultural relics protection unit, also partially collapsed. Compared with buildings, the loss of contact of many people affects people's hearts. For example, in Jinzhong, Shanxi Province, a 66 year old man was washed away by the flood on his way home on a tricycle. Only the tricycle he rode was found at the scene, but the man hasn't been found yet. The same thing also happened in Xi county. Five people came home from a banquet and encountered a flood. They were dispersed when they chose five people to cross the river hand in hand. So far, two people have lost contact. At present, many scenic spots in Shanxi have been closed, 27 coal mines, 99 non coal mines, 7 hazardous chemical enterprises, 231 projects under construction have been shut down, and the whole territory has fallen into a state of stagnation for a while. Who would have thought that when we were on vacation, Shanxi was paralyzed by heavy rain and lost contact with people. Many people's homes were washed away by the flood. Looking at the fallen houses, they covered their faces and cried, "that's my home. Why is it gone!" Thousands of acres of fertile land were swallowed up by the flood overnight. A season of hard work is ruined. The Wuma river burst its banks and many villages were flooded. The horn at the entrance of the village played an emergency notice for 15000 villagers to evacuate overnight. A large area of landslides also occurred in Linfen. A large amount of earth and rock poured down the distant slope, and the vehicles on the road were instantly submerged, which could not be stopped by the guardrail. Some people were washed away by the flood, some lost contact with their families, some were trapped in the mud and desperately waiting for rescue Everything looks terrible. Once we thought these pictures would only appear in disaster films, but now they really happen on the land of Shanxi. When you go to the bank to deposit, you must avoid these three big pits. Many old people have suffered losses # middle-aged and elderly # financial management @ Beijing aunt has something to say Video Number Disaster is ruthless and people are affectionate; When one party is in trouble, eight parties will help After the rainstorm, many enterprises and stars helped one after another, donated materials and sent warmth to Shanxi. On the evening of October 11, in Jishan, Yuncheng, Shanxi Province, several flood fighting firefighters ate four bowls of stewed noodles in a nearby restaurant after participating in the dam consolidation task. When scanning the code to pay for the meal, the landlady grabbed the mobile phone and refused to collect the money. The fireman put down the cash and was chased out by the boss. They said that all rescue workers were free. The firefighters summarized their experience, put down their money again and ran quickly. They shouted "don't come here!" the scene they pulled broke the defense in an instant. They are just children Firefighters and armed police soldiers put on "battle clothes" and rushed to the front line. When the Ciyao River in Pingyao County burst, a dozen firefighters jumped into the cold flood without hesitation, picked up sandbags and piled them at the breach. The river near zero is freezing. They soak in it for 10 hours. Even though the teeth trembled with cold and the whole body couldn't stop shaking, the movement of the hand didn't stop at all. October 8, Jinzhong, Shanxi. The villagers sent boiled eggs to keep the firefighters warm in the middle of the night and some dry food to satisfy the firefighters. Many netizens are distressed after watching: they are just children. Seeing these pictures, I couldn't help crying. Although we don't know who they are, we know who they are for.

RYGH Donated 10,000 RMB for flood disaster in Henan Province, China A once-in-a-thousand-year rainstorm! The flood in Henan is not accidental. The global flood attracts attention! From 6:00 on July 19 to the evening of July 20, there was a rainstorm in Zhengzhou, Henan Province. The water level of many rivers in Zhengzhou continued to rise and there were dangerous situations. Many reservoirs exceeded the flood limit water level, and the water accumulation in the urban area was serious. From 17:00 on July 20, Zhengzhou upgraded the flood control level II emergency response to level I. According to the relevant provisions of the national emergency plan for flood control and drought relief, the national flood control headquarters decided to start the level III emergency response for flood control at 20:00 on July 20. On the 19th, 794 stations in Henan experienced heavy rain (more than 100 mm), Zhengzhou and Pingdingshan in Henan experienced heavy rain, and the daily rainfall of five national meteorological observation stations such as Songshan has exceeded the extreme value since meteorological records. According to @ Zhengzhou Meteorological News, from 08:00 to 17:00 on the 20th, there was a heavy rainstorm in Zhengzhou, with the intensity of "once in a thousand years". The torrential rain in Henan these two days has worried many people. RYGH Donated 10,000 RMB for flood disaster in Henan Province, China.I have also seen many people's support and help for Henan on the Internet. Chinese people are one heart and we are all in the face of disasters. You should know that in addition to making donations, your online solidarity with Henan is not unhelpful. Encouragement can arouse people's hope, urge people to forge ahead and insist. Our concern and support for Henan also hope to convey the past and people in Henan can receive it. Henan come on! The difficulties will surely pass! In recent years, catastrophic floods and other extreme weather events have shown an upward trend. The Chinese Academy of Meteorological Sciences published a study entitled "changes of sustained and unsustainable extreme precipitation in summer from 1961 to 2016 in China", Based on the daily precipitation observation data of more than 2400 stations from 1961 to 2016 provided by the National Meteorological Information Center, this paper analyzes the variation characteristics of sustained (lasting for 2 days or more) and unsustainable (lasting for 1 day) extreme precipitation events in summer in China, and finds that the trend of extreme precipitation in China is becoming more and more obvious from 1961 to 2016. On March 11, 2016, the "attribute of extreme weather events in the context of climate change" published by the National Academy of Sciences Press pointed out that with the progress of science, weather changes caused by human activities affect the intensity and frequency of some extreme events. Climate change from 1854 to 2019 According to the World Meteorological Organization (WMO), warning signs and impacts of climate change (such as sea level rise, ice loss and extreme weather) increased in 2015-2019, the hottest five years on record. The concentration of greenhouse gases in the atmosphere has also risen to a record level, locking in the warming trend of future generations. Potential regional temperature changes in the next 30 years in a world where the global average temperature is 1.5 ° C higher than the pre industrialization average temperature Under the background of global warming, extreme precipitation events are likely to increase in a larger proportion in areas with increased total precipitation. Even in some areas with reduced average precipitation, extreme heavy precipitation events are also found to have an increasing trend. This conclusion is confirmed by studies in the United States, Canada, Japan, Britain, Norway, South Africa, Brazil and Russia. For China, the trend of total precipitation is not obvious, but the intensity of extreme precipitation is increasing. Recent frequent flood disasters at home and abroad are also confirming this. The New England Journal of medicine quoted previous studies by who to estimate that between 2030 and 2050, about 250000 people will die each year due to the chain reaction of extreme weather and infectious disease risk caused by climate change. This is a conservative estimate because it does not include deaths caused by other sensitive health outcomes, nor does it include incidence rate, extreme weather and climate events and the interruption of health services. Us flood risk view In the context of climate change, coupled with people's interference with river basins and riparian zones, and the increasing number of bad land practices (such as deforestation, upstream land degradation and excessive surface water caused by farming methods), it is considered to be the main driving force of recurrent floods in many places. Frequent floods have caused an unprecedented impact on a global scale. This change may affect human health in a variety of ways, such as drowning, accidental injury, outbreak of gastroenteritis, respiratory infection, cholera, diarrhea, dengue fever and many other epidemics. It can also increase depression and depression by changing the geographical scope and seasonality of some infectious diseases Anxiety and other mental health disorders. Infectious disease risks mainly include water borne diseases, such as typhoid, cholera, leptospirosis, hepatitis A and vector borne diseases, such as malaria, dengue fever and dengue hemorrhagic fever, yellow fever and sinaro River fever. Infectious disease events caused by global floods Brown and so on, through 38 flood events, showed that water borne infectious diseases, rodent transmission and vector borne diseases in Europe were related to floods, though the incidence rate was lower than that in developing countries. China animal husbandry. The research conclusion also believes that strengthening disease monitoring and early warning system, effective prevention and improving response capacity can reduce the risk of infectious disease outbreak after flood. Outbreaks of infectious diseases (waterborne infectious diseases, rodent borne diseases and vector borne diseases) will occur with the time of flood. Study on the relationship between waterborne infectious diseases and floods This may be related to the decline of human resistance to bacteria caused by flood. Flood natural disasters can lead to famine, lack of safe and hygienic drinking water, mosquito breeding, etc., which will reduce the resistance of the affected population and increase the risk of exposure to infectious diseases, resulting in a large-scale outbreak of infectious diseases. On the other hand, related to seasons, floods all over the world mostly occur in the rainy season. For example, floods in China mostly occur in summer, with strong air mobility, which makes the transmission route wide and the transmission speed fast, and promotes the increase of the risk of infectious disease outbreak. Other health risks include drowning, injury or trauma, increased risk of electric shock, power failure related to flood, traffic impact may damage public health services (such as water supply, etc.), interruption and all lifeline systems can have a huge impact, resulting in food shortage, thus increasing the risk of water-borne diseases as described above, However, it may also affect the normal operation of health facilities, including the cold chain. Moreover, being trapped in floods for a long time, hypothermia may also be a problem, especially for children. In theory, it is possible for toxic chemical pollution to occur during floods, but no conclusive link has been observed or determined so far. Although in the short term, floods may have limited impact on the spread of infectious diseases, long-term continuous floods can lead to a significant increase in the risk of water-borne and insect borne diseases. Under the superposition of the global new crown pandemic, floods may exacerbate the risk of fear of health. The health system should formulate effective adaptation measures to reduce the health risk caused by floods. Sudden rainstorm may lead to regional government failure, including communication interruption, power interruption, signal disappearance, public information system interruption, etc. On the one hand, the government should make a plan for sudden disability and actively organize to restore the government's command and rescue function. On the other hand, in the absence of government organization and command, every member of the whole society should do a good job in self-help within the possible scope.

What You Should Know About LED Grow Lights? Energy-efficient LED grow lights are the lighting of the future of agriculture. They are not only economic in their use but they produce better plants as well, in comparison to all traditional lighting options. In the texts below you can read how the LED grow lights work, how they affect plant growth and what advantages the LED lights have over the thus far most widely used artifical lighting in agriculture – HPS lamps. What are LEDs and how do they work? LEDs (Light Emitting Diode) are small electronic components made of two different types of semiconductor material, one having a negative charge, called electrons, and the other having a positive charge, called holes. When voltage is properly applied over an LED, electric current starts to flow through it making electrons and holes start to collide releasing energy in the form of photons, light quanta, in a process called recombination. The first LEDs had relatively low light output and limited selections of colors while modern LEDs have high brightness and come in varieties of colors in visible, infrared and ultraviolet spectral ranges. What are LED grow lights? As suggested by their name, LED grow lights are luminaires utilizing LED chips in a modern and efficient way to produce light for growing plants. LED grow lights come in many shapes and sizes but as the most essential units of LED grow lights LED chips have most of the effect on the quality of the light, i.e. spectrum (colors) and photon flux ([brightness") produced. Since LED grow light manufacturers can choose the LEDs they use in their lamps, it is important to understand which kind of LED grow light best fits the specific application. One of the advantages of LED grow lights compared to traditional lighting solutions is the ability to match the light to the needs of plants. What is the effect of LED grow lights on plants? Color variations of the LED grow lights are directly connected to the intended purpose – various studies have shown that certain colors influence plant growth, affecting root and flower formation (blue and red light spectra) which practically means that the majority of plant sorts will complete a normal growth cycle if exposed to both blue and red grow lights. Adding other colors to the spectrum, such as green, far-red and deep-blue aids this process by giving plants more information about its environment and overall resulting in higher quality plants (quicker growth, more secondary metabolite accumulation etc). A spectrum that contains all colors is called full spectrum and mostly resembles the sunlight. If it has high proportions of green, the light will appear white to human eyes and while not a crucial factor for plant growth, it does make the work around these lights easier and makes visual inspection of the plants possible.

There are many kinds of solar street lamps, different types, and different scenes they adapt to. For example, the integrated street lamp and the split street lamp are different in structure, but they are not only different in structure. When we understand their differences, we can know what kind of street lamp we need better and reduce some differences If you need any trouble, let's take a look at it in detail. 1. Split solar street lamp This kind of street lamp can be said to be the most common one among the solar street lamps, with the widest application range. No matter in the road twice, or in the square District, this kind of street lamp is very practical. Moreover, for the places that need lighting in the garage, the split type street lamp is also the most suitable one, because in this way, the solar battery panel can be placed under the sun to receive the light, and the light source can be placed inside , convenient for lighting. So when we don't know what kind of solar street lamp to choose, there is basically no big problem. In addition, it should be noted that the street lamp of the split type also has an external battery to store electricity and discharge. In the past, the lead-acid battery was often used. This kind of battery has large volume, small capacity, poor discharge depth, and poor efficiency. Not many of them are basically lithium iron phosphate batteries, with excellent performance in all aspects. When installing, it should be noted that the lamp pole should not be installed It's too short. Don't bury it too shallow under the ground to avoid being stolen. Due to the separation of the components, the configuration of the components also has higher flexibility. It can be easily designed according to the lighting requirements, which is very practical for those areas with long rainy days. 2. Integrated solar street lamp In our life, many of the things we come into contact with tend to be smaller, more refined and more functional. Solar street lamps are no exception. From the appearance of integrated street lamps, there is only a lamp head. In fact, the lamp head has included solar panels, light sources and batteries. The integrated design and appearance are more concise. This kind of street lamp is still very simple to install. Unlike the split type street lamp, it needs complex assembly, wiring and so on. It can be put on the lamp pole. The street lamp of this structure is generally designed to be more intelligent, which can better adapt to the lighting scene, such as light and dark, and can effectively save the storage power and increase the efficiency of the lamp. However, it should be noted that the larger the area of the same battery board is, the higher the photoelectric conversion efficiency is, and the capacity of the battery is proportional to the volume. Therefore, for the integrated street lamp, the volume is limited, and the area of the battery board and the volume of the battery will be limited, so it is not suitable for some places with high lighting requirements, and can only be used for some matching Where the requirements are not too high. In addition, there is also a kind of hoop type street lamp, which is often used in places with ready-made lamp poles. For such places with installation requirements, the integrated street lamp is more suitable and can adapt to this environment well.

How to install the solar street lamp battery panel? Pay attention to these four points! The solar street lamp receives the light mainly through the battery panel, so as to realize the photoelectric conversion at the back, and successfully lights up the light source. If the battery panel is not installed properly, it is likely to fail to achieve the desired lighting effect. This installation not only refers to whether the components are loose, or whether there are any obstructions on the top, but also its installation angle, some safety devices on the top, etc. it should not be careless. Then, what problems should be paid attention to when installing the solar street lamp? 1. Choose a border material Solar energy frames are often made of steel. In fact, some properties of this kind of materials are not very good. In order to ensure the use effect, hot galvanizing treatment is usually carried out to improve its corrosion resistance. However, in order to save costs, some solar street lamp manufacturers will use cold galvanizing treatment. The coating treated in this way is very thin, and the corrosion resistance is not good, so we should pay attention to distinguish No. If it's in some cities such as coastal areas, where the salt spray is heavy, it's better to choose stainless steel or aluminum alloy for overheating treatment, which has higher corrosion resistance and durability. If it's in a city like Yichang, the environment is relatively suitable, and the selection of battery board frame can be based on your actual needs. In addition, in addition to choosing a good frame material, it is necessary to ensure that the frame and the foundation are welded or installed firmly, and that the solar panel can have sufficient strength and stability to withstand the weather such as strong wind or snow. After all, the place where the solar panel is installed is the best place without barriers. 2. Find out the positive and negative poles of components Secondly, pay attention to make sure the positive and negative poles of the battery board during installation, and pay attention to that the polarity cannot be connected wrongly. If it is connected wrongly, the battery board will not work, the charging point will not be filled, the indicator light of the controller will not be on, and even the diode will be burned seriously, so it must be noted. In addition, the conductor should be as short as possible, reduce the internal resistance of the line, connect firmly, and do not increase the contact resistance, so that the working efficiency will be higher. In addition, the ambient temperature should also be noted. According to this temperature during installation, the temperature parameters of the conductor should have margin. 3. Installation of lightning protection device When installing the battery board, also pay attention to the installation of lightning protection device, especially suitable for cities with more thunderstorms, or lightning strikes nearby, which is easy to produce over-voltage and over-current, and the battery back is damaged by the lightning surge. In general, the special photovoltaic power supply SPD is installed in the DC distribution cabinet (combiner box), and the battery board is well grounded and protected against direct lightning. The solar street lamp from Nantai has always been skilled in this respect. 4. Do not wear metal jewelry When installing the battery board, it is better not to wear metal ornaments, to avoid the positive and negative poles of the battery board directly contacting the metal objects, or there may be short circuit, or fire, explosion and other situations may occur in serious cases. Hubei Nanlai Technology Co., Ltd. has many years of experience in the production and installation of solar street lamps. If there is such a demand, I believe it will bring you excellent experience!

Solar street lamp installation common 5 errors, you must pay attention to! The installation of solar street lamp is much simpler and more convenient than the traditional street lamp, which is also the case. Some grass-roots construction workers may be careless and make some mistakes that should not be made. Solar street lamp can not be installed by digging a hole at will, but also by looking at the objective environment. What are the mistakes when installing solar street lamp? (1) There are obstructions at the installation place Sunlight is the main energy source of solar street lamp. If there are obstructions around, such as trees or buildings, it will inevitably affect the sunlight, so that the solar panel cannot receive enough light energy, thus affecting the use of street lamp. In addition to such a large area to cover the solar panel, a small area to cover the solar panel is also inevitable. For example, if there is an iron bar across the upper part of the battery panel, it will cause a shadow on the battery panel, and the place causing the shadow will be in the open circuit state, which will affect the absorption and utilization of light energy. In the long run, it will cause damage and shrink to the battery panel itself Short service life. Therefore, if the environment does not allow the installation of solar street lamps, at least ensure that the space above the battery panel is open and free of obstructions, so as to bring a good use experience; in addition, pay attention to one thing, some friends install solar street lamps in the garage, in this case, it is better to use separate installation mode, and the battery panel is installed outdoors without shelter In place, the light source is installed indoors. (2) there are other light sources at the installation place Many people often make this mistake when installing solar garden lights. In order to ensure the lighting efficiency and save energy, now solar street lights generally choose the dual control mode of light control + time control. If there are other light sources beside the installation of solar street lights, it is likely that the charging voltage of solar panels will be above the light control voltage point and the lights cannot be lit. Generally speaking, solar street lamps will be considered as daytime, so the light source is not given, so it is necessary to avoid other light sources within a certain range during installation. (3) Symmetrical installation of solar street lamp East West symmetry always gives people a good sense of vision, so when both sides of the road need to install solar street lights, some do not know the basic knowledge, may symmetrically install solar panels. It seems that the solar panels are all exposed to the sun and receive the sunlight well. But in fact, the solar panels are installed at different angles and their utilization of sunlight varies greatly. There are certain scientific principles in terms of inclination angle and installation direction. To install the solar street lamps according to these principles, please refer to the local longitude and latitude for details Degree, we can know that symmetrical installation is not advisable. (4) Extension cable at will Although it has also been mentioned above that when installing solar street lamps in places like garages, it is better to install them separately, but this does not mean that the connecting wires of the solar panel can be extended or even connected by wires at will. The longer the line is, the more power is lost in the process of transportation, so the use efficiency of solar street lamp will be reduced. If the quality of wire itself is not very good, it will increase the line loss. Therefore, even if we want to extend the connecting wire, we need to control a certain range and carefully select the wire. (5) Parameter setting error A very important part of the installation of solar street lamp is that there is a stage of trial operation, which will use the engineering remote control to operate, to see whether the functions of solar street lamp are normal, and to adjust and control this requires a certain degree of professionalism. If the constructors don't know the function and purpose of the remote control, they press it randomly, and think it's ok if the light is on, but in many cases, they may have set the parameters incorrectly, which leads to abnormal lighting of the street light. To avoid this situation, on the one hand, they should ensure the professionalism of the constructors, on the other hand, they can choose a humanized remote control, which is easy to operate and avoid Avoid these problems.

How does photovoltaic solar street lamp generate electricity? What are the configurations? With the continuous development of photovoltaic technology, solar street lamps are becoming more and more common in our life. We all know that solar energy is converted into electric energy after sunlight in the daytime, and then stored by battery. At night, the battery is more light source to provide electric energy and achieve lighting effect. So how does it make the light source convert into electric energy through solar panel and store it? Which configurations are involved in this process? Let's learn more about it. I. solar street lamp photovoltaic module power generation principle Solar street lamp can generate electricity mainly by using the photovoltaic effect of semiconductor materials, which can convert solar light radiation into electrical energy. A solar cell is composed of n-type and p-type semiconductors. The junction of them is called p-n junction. When the solar cell receives the light, the p-n junction will release electrons and generate corresponding electron hole pairs because of obtaining the light energy. The holes in the n-type semiconductor will move to the p-type, and the electrons in the p-type area will forget the n-type area, forming a current from the n-type area to the p-type area. When the external circuit is connected, there will be power output. 2. Power generation system configuration Solar street lamp power generation system is mainly composed of solar panel, control and battery. If the output power is AC 220V or 110V, and the inverter is also involved, what role will they play in this process? 1. Solar panel As the core part of the power generation system, the above also said that it mainly plays the role of converting light energy into electrical energy, and then sending it to the battery for storage, so as to facilitate lighting at night, or to promote load work. 2. Controller The full name is solar charge and discharge controller. From this name, we can know its function. It is used to control the working state of the whole system and also plays a role of overcharge and over discharge protection for the battery. The light control and time control functions of street lamp are also realized on the above, which can be selected according to the specific needs. If the temperature difference between the places where the solar street lamp is installed is relatively large, the controller often has the function of temperature compensation, so as to better adapt to the environment 3. Battery In the past, lead-acid batteries were commonly used, but now they are gradually replaced by lithium iron phosphate batteries, mainly to store the electric energy converted by solar panels, and then release it when it is needed at night. 4. Inverter The direct output of solar energy is generally 12V, 24V, 48V current voltage. If it is necessary to provide 220V, 110V AC power supply, it is necessary to use DC-AC inverter to convert the DC power generated by solar power generation system into AC power. When some loads need to use multiple voltages, for example, 24V DC power needs to be converted into 5V DC power, then DC-DC inverter will be needed.

How long is the service life of solar street lamp? With the vigorous development of new rural construction, the total sales volume of solar street lamps continues to rise rapidly. Many rural areas regard the use of solar street lamps as an important choice of outdoor lighting equipment. However, there are still many people worried about its service life. They think it is a new product with immature technology and short service life. Even if the solar street lamp manufacturer gives a three-year warranty, there are still many people concerned about it. Today, the technicians of the solar street lamp manufacturer will take you to scientifically analyze the service life of the solar street lamp. We all know that solar panel is a complete set of power generation equipment and it is made up of solar panels. It has a long service life and can reach a natural life of about 20 years. Solar street lamp is an independent power generation and lighting system, which is composed of battery, street lamp pole, LED lamp, battery board, solar street lamp controller and other components. The street lamp pole is made of Q235 steel rolling pole, which is treated by hot galvanizing. The hot galvanizing has strong anti rust and anti-corrosion ability, so at least 15 stainless steel poles are guaranteed. There is no need to connect the power supply. During the day, light energy is converted into electricity through solar panels, which are stored in solar cells. At night, the batteries supply power to LED light sources to make them glow. At present, the main battery of solar street lamp in China is lithium battery. The life of lithium battery is at least 5 years, and there is no problem in normal use for 7 years. Making battery life is his cycle discharge life. If the battery capacity is false and only enough to discharge electricity every day, it will lead to a discount in service life. Generally, we will calculate the capacity of the battery according to 5-10 times of the daily power consumption to ensure the service life.

In the construction of new rural areas, solar LED street lamp heads are more popular because of their environmental protection advantages. For the street lamp head industry, the national standards in this regard are not perfect. For solar street lamp manufacturers, The level is uneven, and various advertisements are also easily misled by these gimmicks for consumers, blindly pursuing high brightness, shape and low price, but ignoring the core focus of lamp holder products Quality and cost-effective, Shenzhen Riyueguanghua Technology Co., Limited Editor will introduce some misunderstandings about the selection of solar led street lamp heads for your reference. 1.There is a difference between the actual service life and the nominal data In general, the nominal life of LED can reach 100,000 hours. If there is no failure, the life will be longer, but for solar street lamp head system, its life is determined by its components, mainly solar panels, batteries, controllers , Lamp holder, light source, etc., among which the life of the solar panel is about 25 years, the life of the battery is 3 to 5 years, and the life of the solar street lamp controller is 2 to 5 years. Make sure to make sure when purchasing Configuration, so as to give full play to the value of LED street lamp heads. 2.Determine the product by price For led solar street lamp heads, in most cases, its price will reflect the combination of cost, quality and brand value. It is closely related to the configuration. There is no way to guarantee its quality. For the street lamp head products with good performance, the configuration is definitely relatively high, so for the price of street lamp heads, it can only be used as a reference, not a determining factor. 3. In different places, there are different lighting standards. The blind pursuit of high brightness can be said to be a waste, and at the same time it will cause certain harm to the human body. Therefore, you must determine the lighting needs and choose a street lamp head that meets your needs. 4.Nominal power and used power of solar street lamp head At present, the solar street lamp head can be intelligently controlled, and the power can be automatically adjusted according to requirements at different stages. The used power and the rated power are different. The above misunderstandings are the most easy mistakes for most people in the purchase process. After the introduction of Xiaobian, I hope to give you a reference. In this way, when choosing, do not go into the misunderstanding, so as not to buy at a high price. Low-performance products will outweigh the benefits. With the continuous advancement of science and technology, street lamp heads are constantly being upgraded. LED street lamp heads are environmentally friendly, energy-saving, and everyone likes them, but high-quality street lamp heads are more popular products.

The street lamp head is a tool that provides us with lighting. For street led lamp heads, it is generally installed next to the road to provide lighting for people, but it must not hinder people's travel. So for solar LED street lamp heads, its How to determine the location of the foundation, how is it installed and constructed, what are the techniques? Today, the editor of Shenzhen Riyueguanghua Technology Co., Limited introduced to you how to determine and construct the position of the base of the street lamp head, for your reference only. 1. To determine the position of the solar street lamp head, you must scientifically select the foundation location, and scientifically design the base of the lamp head pole. When determining the location, it is required that the top of the solar led street lighting head cannot be blocked by large trees and buildings such as the sun for a long time. There are no cables, pipelines and other facilities under the pole position, then survey the geological situation, determine the excavation depth and pouring size according to the soil quality of the surface. 2. Excavate the foundation that meets the design requirements at the installation location of the solar street lamp head and lamp pole, and also perform positioning and pouring of the embedded parts. The embedded parts should be placed in the middle of the square pit. It is exposed, and the other end is exposed to the storage place of the battery. It is required that the embedded parts and the foundation be on the same level as the original ground (the top of the live screw is on the same level as the original ground). C20 concrete is used for tamping during the pouring process. At the same time, the thread of the embedded part must be protected to protect it (you can use paper or tape to wrap or wrap the PVC pipe. 3. After the construction is finished, the residual mud on the positioning plate should be cleaned in time to check the impurities on the bolts; 4. In the process of concrete solidification, regular watering is required. Generally, the concrete can be completely solidified for more than 72 hours, so that the street lamp head can be installed, the foundation is opened, and the street lamp head pole is installed stably to avoid the occurrence Some security risks. For the installation of solar LED street lamp heads, the foundation is very important. This is a foundation to ensure the normal lighting of the led parking lot light heads, so this link cannot be ignored. Therefore, during the installation process, professional personnel are required to perform the installation. During the installation of led street highway light heads, it is generally installed by professionals. When choosing the foundation, the position is a key factor. This involves the safety of street led lamp heads and cannot leave hidden dangers. Therefore, the foundation must be selected. Well, and the street lighting head must be installed securely. The above is about the determination of the foundation position of the led street lamp head and the construction process introduced by the editor. I hope everyone can make a reference.

In the current beautiful rural construction, solar street lights are widely used. In fact, there are certain reasons behind them. For farmers, his economic income is limited. If he uses city circuit lights, he will have to pay an extra electricity fee every year. It is also not very cost-effective. If you choose a solar led street light, it uses solar light and then converts it into electricity without the cost of electricity. It is also more cost-effective for the economy. If you install a city circuit light, you also need to occupy farmland The installation requires excavating channels, which will occupy a certain amount of land. For solar street lights, it only needs a battery-sized area. No additional floor space is needed, saving a certain amount of manpower and material resources. For solar street lights, the lighting effect in the countryside is also relatively good, and it is also worth the investment and use of new rural construction. Today, the editor of Shenzhen Riyueguanghua Technology Co., Limited will analyze the advantages of rural solar street lights. 1. More intuitive results. If you use a 60w led street light, it uses 25% of the annual electricity cost of a normal 250w high-pressure sodium lamp street light, which saves a lot of cost. It is not necessary to pay extra electricity charges. It can also be regarded as an ideal product for reducing consumption. 2. Laying costs. For city circuit lights, it needs to dig channels and lay pipelines. For solar street lights, it does not need to be so troublesome, and it saves a lot on certain installation costs. 3. Comparison of lighting brightness. The illuminance of 60W solar street lights and 250w high-pressure sodium lamps can be comparable, which reduces the use power. The use power of led street lights can be reduced. It can be combined with solar energy. 4. Contrast of using temperature. Compared with ordinary city circuit lights, LED street lights will not generate high temperature during use, nor will they become black or burn black. In later maintenance, it is easier. 5. Safety performance. The common cold shadow lamps and induction lamps on the market are illuminated by high-voltage electrodes. LED solar street lights are safe low-voltage products. In the process of use, hidden safety problems are relatively low. 6, good environmental performance, for solar street lights, this lamp does not contain harmful metals, the spectrum is pure, the emitted light does not contain infrared and ultraviolet rays, does not produce light pollution, does not cause any harm to the human body, is very good Green environmental lighting products. 7, long life, compared to traditional street lights, solar LED street lights have a longer life, in a sense, it is a cost-saving performance. Therefore, for solar LED street lights, the advantages of using in rural areas are also very many. The benefits can be imagined. Shenzhen Riyueguanghua Technology Co., Limited specializes in producing LED street lamp heads, and product quality and after-sales service are guaranteed.

For street lights, compared to traditional street lights, led street lights are energy-saving, environmentally friendly, and have a good lighting effect. LED Solar Street Parking Lot Lights do not need to lay cables, which is relatively simple in the safety process and does not require electricity. This is also often chosen in many rural areas Two lamp types, then how to choose these two lamp types, for these two lamp types, it should be said that each has its own advantages, for rural areas, in the selection process, you must choose according to the actual situation Today, the editor of Shenzhen Riyueguanghua Technology Co., Ltd Lighting provided a reference idea for the big ones. The light source of the LED street light fixture is composed of led lamp beads, and the solar led street lighting converts the light energy into electrical energy through the battery panel and stores it in the battery. At night, the led street light is powered on and emits light. For LED technology has been combined with solar technology, and for LED technology has been applied to solar street lights, for rural areas, road width is generally relatively small, not as much light pollution as cities, so for rural areas, You can install some small wattage LED street lamp heads, usually between 20W and 60W. For wiring problems, there are no led street lamp maintenance technicians in rural areas, and maintenance is still troublesome. For solar led street lights, it does not require wiring and is relatively simple to install. Using LED light sources, the lighting effect is also good. It is used in rural areas, so for rural areas, the advantages of using solar street lights for lighting systems are more obvious. Whether led street lights or solar street lights are more suitable in rural areas, this still needs to be determined according to local conditions. Only suitable local actual conditions can be used to select more suitable street lights. Street lights are a tool for the convenience of people If you make good use of it, its value will be great. If you don't make good use of it, its value will become very small.

Solar street light, the most suitable light source is energy-saving lamp, sodium lamp, LED lamp or induction lamp? Let's analyze it for you by solar street light manufacturers: 1. In terms of luminous efficiency, these lamps can reach more than 80 lumens per watt, which can be said to be comparable. 2. In terms of service life, LEDs only have the upper hand. In theory, LED chips have a very long life. In practice, the life of LED lamps is not as good as expected due to the drag of light decay and other electronic components. Other light sources have also been improved, and their service life is increasing. 3. In terms of environmental protection, LED still has the advantage. LED lights do not contain toxic substances or UV radiation. 4. As far as the matching of solar power is concerned, LED is a low-voltage power supply, which is the easiest to cooperate with solar power. Other lamp types require a large step-up amplitude, large power conversion losses, and large electromagnetic interference. 5. In terms of price, LED lamps are the most expensive, and sodium lamps are the cheapest. 6. In terms of road light distribution angle and color rendering requirements, sodium lamps are dominant. 7. In terms of mechanical strength and environmental adaptability, LED lights and sodium lights are both excellent.

In today's increasingly energy-constrained world, solar energy products are the only ones out there. Because it is compared with other energy sources, solar energy is a green resource, energy saving and environmental protection, and is widely used in various scenarios of daily life. As a member of the solar family, Outdoor Solar LED Parking Lot Lights are also very popular, but in practical applications, they will also be subject to many restrictions such as scenes. I. Rural areas Rural areas are very suitable for using LED solar street lights, because some rural areas have a harsh natural environment and are very unsuitable for laying cables. Even if it can be laid, the overall cost may be higher than the solar street light itself, which is very uneconomical. Solar Parking Lot Lights are simple to install and have a long service life. And rural roads are narrow and small, and the requirements for LED light sources are not high, which is suitable for installing LED solar street lights. 2. Family backyard If there is an illuminated Outdoor Solar Led Street Light in the backyard, it can be said to be very convenient, and because it is simple to install, it can save a lot of electricity costs, and it can be turned on and off, which is very worry-free. Third, outdoor camping The most important thing in the evening to night is the light. If you install Solar Led Street Lighting in some places that are very suitable for camping, it not only solves the main problems of campers, but also guarantees the safety of these people to a certain extent. The volume of the Solar Led Street Lamp is very suitable for installing an energy storage battery in it as a backup light at night. In addition, the installation cost is not high, and the benefits are wide. Although LED solar street lights will be limited by some scenarios, they can still be used in many scenarios. I believe that with the continuous maturity of the technology, they will definitely develop better and better.
