LEDs are widely used in every lighting industries because of their energy saving, long lifespan, and environmentally friendly. However, there are 5 external factors will shorten their service life.
1. Drive current: The rated voltage and rated current of the LED lights are unchangeable. Therefore, there are different sizes of LED power supplies on the market, and the most common are 12V and 24V DC drive power supplies. For most of the constant voltage LED tape lights currently on the market, the output voltage and power of the power supply must be appropriate, otherwise, it may reduce the life or even damage the LED lights.
2. Corrosive environment: In some areas with serious pollution or in some chemical manufacturing plants, it is best to use LED lamps with protective devices to avoid damage caused by contact with corrosive materials.
3. Operating temperature: The temperature will affect the light decay and service life of the LED. Generally, LED lights are used at temperatures ranging from -20 ° C to 65 ° C. Excessively high or low temperatures will affect the work of lights. In order to avoid the light decay that caused by high temperature, it normally increases the heat dissipation area or installs the active heat sinks.
4. External force: During installation or use, the collision of hard objects or sharp objects will cause the LED to be damaged or even completely destroyed. Therefore, the LED light should be installed as far as possible in a place that is difficult to reach.
5. Humid environment: Whether it is production, storage or use, the LED should be avoided in a humid environment, because the moisture can easily cause the LED to be wet and the short circuit.
These are the five major external factors that affect the life of LED lights. If you have other questions about LED lighting, please feel free to contact us. We are a manufacturer of LED lights in China, specializing in the production of LED light strips and LED plant lights.

How to develop in the future in the era of LED healthy lighting
LED healthy lighting has been proposed by the market in 2015 for three years. In the past two years, LED healthy lighting is still in its infancy.
With the continuous advancement and popularization of technology, the number of manufacturers involved in healthy lighting has increased in 2018, and a lot of traditional LED strip suppliers have gradually joined the camp. With the further improvement of technology and further cost reduction, LED lighting will quickly enter the era of healthy lighting.
LED health lighting refers to the light emitted by LED products that do not cause harm to the human body, especially for eyes. However, most of the LED strip factories are more focus on improving light efficiency and reducing costs. Some inferior products, short-wave blue light specific gravity, which will lead to visual fatigue, causing vision loss.
Illumination has expanded into the field of non-visual biological effects. Many studies have shown that the non-visual effect of light, the light perceived by the ganglion cells of the retina can affect the release of melatonin, sleep, and biorhythm at night. In other words, the influence of light on humans is not only the influence of the direct visual sensory system but also on other non-visual sensory systems.
Sunlight is the most suitable and most comfortable light source for human beings. The current LED health lighting is also the maximum imitating natural light. At present, there are two ways to reach the full-spectrum light source in the market. The first is a blue chip to stimulate the phosphor, and the other one is a violet chip to stimulate the RGB multi-color phosphor. The R2835FS series of LED strip lights launched by MLDR CO., LTD., its spectrum is very close to the natural spectrum.
LED healthy lighting is not only the manufacture of LED lights but also the study of the relationship between light and human health.
Although there is still a long way to go, with the close cooperation of various area, LED health lighting will have a great future. For LED strip manufacturers, more attention should be paid to the development of LED healthy lighting.

Which is better for LED grow lights and HPS lights?
New agricultural facilities such as greenhouses, plant factories, and vertical farms play an extremely important role in the development of modern agriculture. In order to avoid the adverse effects of weather and increase the yield, artificial lighting is used for plant supplement lighting. After years of development, LED grow lights have become the most important light source in agricultural lighting. Because of the lower price and high light efficiency, the high-pressure sodium (HPS) lamps still have a certain market share. The following is a comparison of the two most common agricultural lights currently on the market.
1. The HPS light is composed of mercury, sodium, neon arc tube wick, glass bulb, and getter lamp head. HPS lights of different powers need to use ballasts of corresponding specifications. The LED is also called a light-emitting diode, and the core portion is a wafer composed of a P-type semiconductor and an N-type semiconductor.
2. The HPS lamp tube has an illumination angle of 360°, and most of the light must be reflected by the reflector to reach the designated area. The spectral energy distribution is roughly red-orange, yellow-green, and blue-violet (only a small part). The LED light source has wavelength tunability, and can emit monochromatic light with narrow light waves, such as infrared, red, orange, yellow, green, blue, etc., and can be arbitrarily combined according to different needs.
3. The life of the HPS light is about 20,000 hours, which generates a lot of heat during work. As a semiconductor light source, LED grow lights can last up to 50,000 hours and produce relatively little heat, which can be installed close to crops.
4. Studies have shown that the gas exchange, chlorophyll content, accumulation of photosynthetic pigments, and transpiration rate are higher under LED lighting. The special spectral ratio of LEDs can also be used for the different growth of plants.
The advantages of HPS lights and LED lights are significant compared to other light sources. The initial investment cost of LED is higher than that of HPS lamps, but the overall cost is lower. And with the development of LED technology, the production cost of LED grow lights will further decrease.

What are the factors that affect the life of LED strips?
LED light strips are widely used in various places for their long life, easy installation, and energy saving. The long lifespan is the most representative parameter. Therefore, the service life of the LED light box light bar has become one of the most concerned issues in the industry. Whether it is for the LED light bar manufacturers or users, it is necessary to understand the factors affecting the life of the LED strip lights. There are three main factors that affect the life of the LED strips:
1. The quality of the lamp bead directly affects the service life of the LED strip. The LED is composed of a variety of materials, and the quality of each material is totally different. For example, the heat dissipation of the pure copper bracket is superior to that of the iron bracket and the aluminum bracket. The materials vary widely, and the connecting wires are also divided into gold wires and gold-plated wires. Therefore, the quality of the LED is inseparable from the quality of the raw materials used. A good and stable LED is inevitably the most stable combination of various materials. The theoretical lifespan of LED strip lights can reach more than 50,000 hours. However, due to improper competition in the market, some packaging factories have chosen the inferior raw materials in order to reduce costs, thus greatly affecting the service life of LED strips.
2. The service life of LED light box light strip is closely related to the heat dissipation of PCB. The heat dissipation performance of PCB directly affects the series of common problems such as whether the material structure of LED light strip is stable and the light decay is serious. Therefore, whether to use a high thermal conductivity PCB also plays a very important role in the service life of the LED lights.
3. When the driving current of the LED light box light bar is greater than the rated current, the light decay will be increased. The lower the driving current of the LED light box light bar, the smaller the heat, the lower the brightness. Increasing the drive current exceed the rated current, the heat of the LED light box light bar rises, which will shorten the service life.
The above is a brief description of the factors affecting the lifespan of LED strips. If you have any questions and requirements about LED lighting, please contact us without hesitate. As a China LED strip lights manufacturer, we are committed to creating win-win cooperation with our customers.

How to install the LED light strips in the light boxes?
The arrangement of the LED strip lights is really important to the whole lightbox's lighting effect. If the configuration is improper, there will be problems such uneven light effect. The configuration of the LED light bar is determined according to the different occasions, different brightness requirements, and sizes of the lightbox. The following is a brief introduction of how to configure the LED light bar.
The small light boxes are mainly used in largely residential areas, shopping centers, supermarkets, schools, entertainment and leisure places, etc. For the small lightbox, since the size of the lightbox is small, and the requirement for brightness is relatively low, it is only necessary to arrange the light bars up and down or left and right to form up and down, left and right pairs of light. The installation is very simple and convenient.
The application places of large light boxes are mainly distributed on streets, large shopping malls, hospitals, exhibitions, commercial downtown, stations, airports, parks, etc. Because the size and thickness of the light boxes are different, it's recommended to use LED strip backlighting. The LED strips are characterized by a very flexible size, which can meet different lightbox sizes, different brightness requirements, and different application scenarios.
According to the thickness and brightness requirements of the lightbox, the number of light bars and the distance between the strips are different. The higher requirement of brightness, the number of light bars should be increased or the high brightness LEDs should be selected. Similarly, the thinner the lightbox, the more LED strips are required.
The above is a brief description of how to install the LED light bar. If you need more detailed LED lights information, please visit our official web.

The world's first underground fully automatic LED lighting plant factory
The use of artificial lighting and nutrient solutions to grow leafy vegetables is no longer a new thing, and many Japanese companies use the waste factory to plant vegetables. A plant factory in Chiba Prefecture, near Tokyo, differs in that the boxes from which the seedlings are grown are transported to the plant factories in the underground space, and the vegetables that are finally grown are sent to the ground by conveyor belts to achieve full automation. Planting vegetables.
This is the world's first underground fully automated plant factory, located in an idle underground municipal complex. The top of the underground tunnel of about 3.1 kilometers is about 5 meters from the ground, the interior is 6 meters to 8 meters wide, and the height is about 4 meters. It was first built in 1995. It was originally planned to be used in the local municipal integrated pipe network and was left unused. Ito Electric Co., Ltd., which develops automation equipment, cooperates with the Chiba Prefecture Corporate Land Administration to utilize this idle underground tunnel. In December 2017, this unique plant factory was built.
According to Okada Akira, head of the Plant Factory Development Headquarters of Ito Electric Co., Ltd., starting from December 2017, the plant factory began to test and cultivate 200 vegetables per day, including leafy vegetables such as lettuce and edible flowers. According to the plan, by 2020, the factory can enter the mass production period and produce 2,500 per day. By 2022, the daily output will be further expanded to 5,000. By then, the underground plant area will reach approximately 3,200 square meters, and the above-ground working area will reach approximately 600 square meters.
It is reported that part of the tunnel has been opened up as a fully enclosed plant growing area with an area of about 120 square meters. Through the plastic wall curtain, some vegetables such as lettuce can be seen layered inside.
According to Okada Akira, the plant has been fully automated. After cultivating the seedlings on the ground, the modular vegetable box is sent underground through the conveyor belt. The LED light and nutrient solution transport in the underground plant can be completed automatically. The underground plant factory can be transported to the ground for sale after 24 days of cultivation.
The staff also brought freshly harvested lettuce to the reporter for tasting. Due to the complete cultivation in a non-polluting environment, these lettuces can be eaten directly without washing, and the taste is also very good.
Okada Akira said that the price of vegetables produced at this plant is now the same as that of ordinary lettuce, and there is room for further cost reduction in the future. When the daily output reaches 5,000, the ground only needs about 10 staff for seedling, harvesting and equipment maintenance. In the future, they plan to develop more automation equipment, with the goal of reducing costs by 20% to 30%.
According to Toshihiko, the deputy director of the Chiba County Enterprise Land Administration, plant factories usually need to consume a lot of electricity for temperature control and lighting, but this plant is set up in an underground tunnel, constant temperature and humidity throughout the year, which can save a lot of air-conditioning electricity costs. . In addition, due to the close proximity to the consumer market, the vegetables produced do not need to be transported over long distances, saving a lot of logistics costs.

What cause dead LEDs on LED strip lights
Sometimes there will be dark areas in the light boxes. When you open the canvas, there are several LEDs on the LED light strips. After using for a while, there are several LEDs can't work, which is the phenomenon of dead LEDs that people in the industry say. So what are the reasons for the dead LEDs?
Firstly, the quality of the LED lights is the direct cause of the dead LEDs. The use of inferior lamp beads will greatly increase the chance of dead LEDs of LED light bars. LEDs are composed of various materials, such as brackets, chips, wires, glues, etc. If any of these materials are low quality may cause LEDs to die prematurely.
Secondly, a LED or line on the serial-parallel circuit board is disconnected, causing the other LEDs to be off. This situation will affect the normal operation of the whole segment of the led lights. The reason is that due to the low working voltage of the led lamp, it is generally necessary to use string and parallel connection to adapt to different working voltages. The more LED lamps in series, the greater the impact, as long as one of the LEDs or one of the lines in this LED strip is disconnected, which will cause the entire LED light fixture.
Moreover, the wiring error also will cause the LED lights to burn out. If the LED low voltage tape lights are directly connected to 220V AC power will damage the lights. If the power supply is correct but the lights are not working, it may be because the positive and negative poles being reversed.
The last reason is that the physical damage during packaging, transportation, and installation. In the packaging, transportation, and installation of the LED light strip, various physical damages occur, causing the dead LED.

Abandoned mine + LED grow lights + other systems = vertical farms
The reduction of waste coal has become a global environmental consensus, so more and more coal mines will be closed in the future. Scholars at the University of Nottingham are beginning to think about the future use of waste mines. They propose vertical farms. The concept is that a mine is a ready-made greenhouse that can be turned into a fully functional farm with the addition of LED lighting and irrigation systems.
According to reports, scholars believe that deep farms have some obvious advantages: they are not affected by the weather, and the temperature of the ground floor does not change much, and expensive temperature control equipment is not needed. Safa of the University of Nottingham said: Tunnels and shafts do not need heating equipment, and even if they do, they consume less electricity, so they are very attractive for food production. We designed a central shaft for mounting robots. With these robotic arms to take care of the crops and harvest, the entire system costs only about $38,000 to build, and then the operating costs are lower. The LED plant grow lighting system does not consume much electricity.
Vertical farms are suitable for vegetables and fruits with short growth cycles, such as spinach, kale, basil, mint, strawberries, mushrooms, carrots, eggplants, etc. Their trials show that a small well-type small farm can produce 80 tons of crops per year. Moreover, production is not affected by the seasons and can reach 10 crop cycles per year, while British outdoor farms only have 4 to 6 times.

Malcolm Yare, Development Manager of Current Agriculture at GE, said that the LED grow lighting is a key factor in the successful growth of any crop, and we will create more arable space in industrial and urban areas by combining the most efficient wavelengths and optimal environmental conditions. Increase global crop yields in a way that is sustainable in business and the environment, surpassing traditional farming methods.

How to install the LED strip curtain lights
With the popularity of thin advertising light boxes and stretch ceilings, LED lattice curtain strips have become an important backlight source. Compared with short-life and fragile fluorescent tubes, LED strips have become an irreplaceable backlight source for the advertising lighting and house lighting because of their higher brightness, longer service life, and easier installation. They are widely used in light boxes, showcases, home decorative lighting, etc.
The light strips with the optical lenses are suitable for advertising light boxes with a thickness of less than 10cm because its luminous angle is large than 170°, which can reduce the number of light strips used and reduce the cost. If the thickness of the advertising light box is more than 10cm, it is recommended to use the ordinary LED strips.
The curtain strip lights should be adjusted according to the thickness and size of the light boxes. In order to avoid dark areas, the spacing of the light bars cannot be too large. At the same time, we should pay attention to the correct wiring during installation. In general, the white line represents the negative electrode, and the lines of other color represent the positive electrode. In addition, the LED light strips are generally the low-voltage lights. It should be noted that high-voltage power cannot be directly connected, otherwise the LED lights will be damaged.
