When facing LED lighting fixtures, many people have a favorable impression, after all, LED lighting fixtures have a relatively large usage and complete functionality. When it comes to LED plant lights, some growers have a clear preference for these types of plant lights. Many people may have doubts about whether LED plant lights are worth choosing when they have not been exposed to them. You should know that this type of plant lamp is worth choosing with confidence. Now let's have a simple understanding of this product. There are many people who choose LED plant lights, and one important reason is that these types of plant lights have very distinct advantages. Whether you are a newcomer to entrepreneurship or someone with a relatively large scale, this type of plant lighting is a good choice. There are two main reasons. Firstly, LED plant lights have very low power consumption, and compared to other lighting fixtures, they can save a lot of electricity in long-term use.   Furthermore, its cost is very low when purchased, and its lifespan is also relatively long. If used for a long time, it can also save a lot of costs. LED plant lights have a relatively complete spectrum of colors, including both red and blue spectra. Regardless of the type of spectrum, it can be switched freely during the irradiation process, which can also meet the different lighting needs of different plants.   The application range of LED plant lights is becoming increasingly widespread, and their space occupation is also very small. Throughout the entire application process, it can be used not only in greenhouses, but also in plant factories. Nowadays, some families also use this type of plant lamp in their daily lives. Because of this, for those in need, they can make choices with confidence.

For urban farmers, plants blooming and bearing fruit under their careful care are the best soulful chicken soup. For indoor planting, there are actually significant drawbacks. Due to the inability to provide sufficient natural sunlight indoors, in some areas with poor climate conditions or long winters, insufficient natural light can severely limit plant growth, greatly reduce plant growth, and even lead to poor root development, yellowing of leaves, and leaf shrinkage. In this context, "plant growth lamps" have emerged. Today, we will take you to comprehensively understand the principle, types, and use of plant growth lamps. principle Plant growth lamps are designed based on the principle of photosynthesis. Photosynthesis is the process in which plants use light energy to convert carbon dioxide and water into energy and oxygen. Plants absorb light energy through chlorophyll and participate in the photosynthetic electron transfer chain through photosynthetic pigments. Plant growth lamps can simulate specific wavelengths and intensities of natural sunlight, which are absorbed by plants, providing them with the necessary light energy and promoting their healthy growth. type According to the type of light source, plant growth lamps are mainly divided into the following three categories: 1. Fluorescent lamps: Fluorescent lamps use gas discharge to generate ultraviolet light, which is then converted into visible light through fluorescent powder, making them relatively inexpensive. 2. High pressure sodium lamp: a high-intensity discharge lamp that produces mainly yellow and red wavelengths, with high light intensity and irradiation area, suitable for large-scale plant planting. 3. LED lights: Multiple light-emitting diodes can release light of different wavelengths according to the design. LED lights have low power consumption, long lifespan, and adjustable spectrum, which can meet the needs of different plants at different growth stages. Among them, LED plant growth lights have gradually become mainstream. Compared with traditional fluorescent lamps, high-pressure sodium lamps and other light sources, LED lights have a very significant energy-saving effect, which can save 75% -90% of electricity consumption. High quality LED plant growth lights can work for 30000 hours, far exceeding the lifespan of traditional lamps, and generate less heat, avoiding the risk of plant leaf burns and other risks. LED plant growth lights can adjust the appropriate spectrum, light intensity, and irradiation time according to the characteristics and stages of different plants, in order to achieve a better growth lighting environment. LED lighting fixtures do not require replacement of tubes or filaments, resulting in low maintenance costs; LED plant growth lights do not contain toxic substances such as mercury and lead, and do not produce harmful substances such as ozone during use, which poses no harm to the environment and human health.

The growth of all things relies on the sun, and light plays a crucial role in the growth process of plants. However, the light environment varies under different geographical conditions. In order to increase crop yield, improve crop quality, and control the growth cycle, various types of plant growth lights have been widely used in indoor and greenhouse planting. What is the difference between plant growth lamps and ordinary lighting fixtures? Difference 1: The plant growth lamp targets plants and mainly provides sufficient light for their growth, thereby promoting healthy growth. Ordinary lighting fixtures are mainly used for people's lighting or decoration, and the two cannot be confused. Difference 2: Plant growth lamps are made based on the principle of plants using sunlight for photosynthesis. Currently, the main popular types on the market are full spectrum and red blue spectrum plant growth lamps. The spectrum of the full spectrum LED plant growth lamp is mainly in the visible light band of 400nm~720nm (excluding the green light band), while the spectrum of the red blue spectrum plant growth lamp is mainly concentrated in the red and blue light bands. However, the spectrum of ordinary lighting fixtures is not as concentrated as that of plant growth lamps, and the light beads used by different manufacturers have significant spectral differences. This also means that, with the same degree of electricity, the converted light energy from plant growth lamps can be effectively utilized by plants, while when using ordinary lighting lamps to supplement light for plants, a large part of the useless light energy for plants is wasted. Therefore, it is recommended to choose a professional plant fill light when adding light to plants. The Sansi Spreading Wings Lamp series products, designed specifically for plants with high light requirements such as roses and tomatoes, have significant advantages and are popular both domestically and internationally. They effectively solve the problem of low light and low light for indoor plants in different geographical areas such as high latitude, high cold, dense fog, and rainy weather. Full spectrum mimics sunlight, caring for the healthy growth of plants The sunlight contains ultraviolet, visible, and infrared light, and the majority of the ultraviolet light reaching the surface is absorbed and filtered by the ozone layer. The visible light band plays a major role in the growth stage of plants. XINYUDA plant growth lamp imitates sunlight and meets the lighting requirements of the entire plant growth process.

LED beads are particularly popular nowadays, whether it is making artistic light sources or direct lighting fixtures, they have irreplaceable and increasingly important positions. Today, the editor will introduce to you the relevant issues regarding the production instructions and parameter usage precautions of LED beads. 1. LED Beads with Excellent Application Current 1. The normal working current of 0.06W LED beads is 20mA, and the normal working current of 0.2W LED beads is 60mA. 2. Overcurrent protection: Excessive current can also cause LED beads to die out and the brightness to rapidly decay. In circuit design, different current limiting resistors should be matched according to the voltage drop of LED beads for series protection to ensure the normal operation of LED beads and achieve the best working state. 3. LED beads with the same power should operate under the same current conditions. If the current is too high, the lifespan of LED beads will be reduced. If the current is too small, it cannot achieve the required light intensity. 2. Brightness testing and product usage instructions 1. When testing VF, brightness, and wavelength, the normal operating current should be set based on the actual power of the LED beads. When testing VR, the IR should be set to 10uA, and when testing IR, the VR should be set to 5V. When detecting and using LED beads, it is necessary to provide the same current to each LED bead, i.e. using constant current detection, in order to ensure uniform brightness measurement. 2. When using LED beads that have been separated by light and color, they should be classified according to different BIN levels, and different BIN level products cannot be mixed and applied to the same product, resulting in poor product consistency. If mixed BIN levels are necessary, adjacent BIN levels can be used together, but should be avoided as much as possible. 3. Precautions for anti-static measures 1. Static electricity and surge voltage can damage LED beads 2. All equipment, instruments, and workbenches that come into contact with LED beads should be equipped with grounding wires, especially the soldering iron and tin furnace that are welded must be well grounded; Measures to resist surge voltage are required in devices using LED beads. 3. Operators must wear anti-static gloves and wristbands, and ensure good grounding. Before coming into contact with LED beads, static electricity must be eliminated. The soldering iron or immersion welding equipment must be grounded, and an ion fan should be used to eliminate static electricity. It is strictly prohibited to touch the two pins of LED beads with bare hands. 4. Anti static wristbands must be tested daily, and those that fail must be replaced. Xinyouwei Optoelectronics Factory supplies F3/F5 LED beads, wholesale in stock, with reasonable prices. 4. Working and Storage Temperature of LED Beads The operating temperature of LED beads is -30 ℃ to 60 ℃, and the storage temperature is -40 ℃ to 85 ℃. When powered on, make sure to work at high temperatures above 60 ℃. If there is any high temperature work, be sure to take heat dissipation protection measures.

Planting some green plants indoors is an ideal choice for decorating a house and relaxing the mood. Plants can not only purify the air, but also be used as decorations at home. However, planting indoors also has a drawback - insufficient sunlight, and without sufficient light for photosynthesis, plants cannot flourish. If the growth of plants can meet the following requirements, most plants can maintain good growth indoors. Temperature and Light Appropriate temperature is another important factor for plant growth, but due to different climates of origin, various plants have different requirements for temperature. If the temperature is higher than the maximum temperature or lower than the minimum temperature, it will damage the growth of plants and even cause plant death. Therefore, before planting, we must first know the temperature suitable for plant growth. For example, roses, honeysuckles, and lilacs in temperate and sub cold regions can usually tolerate low temperatures of around -20 ℃. Temperate and temperate native chrysanthemums, plum blossoms, and magnolias can usually withstand low temperatures of -5 ℃. Cactus and rubber trees are native to tropical and subtropical regions, so they need to be kept at 15-18 ℃. Plants must also grow, develop, bloom, and bear fruits in sufficient sunlight, but indoor plants often cannot grow normally due to insufficient sunlight. Nowadays, LED plant growth lights are becoming increasingly popular, as they can replace sunlight to provide a comfortable growth environment for indoor plants. Different types of plants have different requirements for light intensity and exposure area. We need to choose the appropriate plant growth lamp based on the different types of plants. improve air circulation Many people believe that placing plants indoors can absorb carbon dioxide and purify the air, which is true. However, if plants grow in enclosed spaces, they will undergo anaerobic respiration and release carbon dioxide, which is harmful to the human body. And plants will also be susceptible to bacterial invasion. Therefore, if planting indoors, it is necessary to open the windows at the appropriate time. It is generally recommended to open it at 9:00 am and 11:00 pm or 2:00 pm and 4:00 pm, during which the temperature rises and harmful gases deposited at the bottom of the atmosphere disperse. Alternatively, we can move the plants near windows or balconies for ventilation. Otherwise, the plants planted are very susceptible to illness. curing If you want plants to survive for a longer time, careful care must be taken. For potted plants, soil fertility can only last for about a year. If the root system withers or grows too fast, it must be pruned to prevent damage to the plant. If it is a slow growing plant, it can be maintained for two to three years without changing the flowerpot. If there is dust on the leaves, it will affect the photosynthesis of the plant. Therefore, it is necessary to wipe the leaves with a sponge or damp soft cloth and spray the plants with water.

The steps for installing plant light tubes are as follows: Firstly, determine the lighting area you need, the size and type of plants, and select the appropriate plant light tube. 2. Plant light tubes usually come with their own hangers or fixing clips, allowing them to be fixed to plants in different positions. If you need to fix the lamp tube to the ceiling, you need to install a fixing hook or lifting ring in the appropriate position. 3. Confirm if the location you want to install is suitable and determine the required power supply. 4. Before installing the lamp tube, ensure that the power is cut off to avoid any accidents during the installation process. 5. Use an electric drill and appropriate screws to fix the fixing bracket, hook, or ring to the ceiling. 6. Hang the lamp tube and use the attached fixing buckle or other accessories to secure the lamp tube. 7. Plug in the power and turn on the light tube. 8. Confirm whether the lamp tube emits light normally. If not, try reinstalling or making other adjustments. Precautions: During the installation process, it is necessary to ensure that the power is cut off to avoid bodily injury or damage to the lamp tube. 2. The lamp tube must be installed at an appropriate height to cover the range of plants you want to plant. Whether it is too high or too low will affect the effect of the lamp tube. 3. Try to avoid allowing the light from the lamp tube to directly illuminate people's eyes, in order to avoid damage to vision caused by the light. 4. Regularly clean the lamp tubes and other accessories to maintain their optimal condition. In summary, when installing plant light tubes, it is necessary to pay attention to safety, select appropriate types of light tubes according to the needs and occasions of plants, and correctly install and regularly maintain them in order to allow plants to grow and develop better in indoor environments with poor natural lighting.

Plant growth lamp, also known as plant lamp or plant specific lamp, is a device that simulates the solar spectrum and provides light for indoor plants. The growth of indoor plants requires photosynthesis, and the spectrum and intensity of natural light do not always meet the needs of plants, especially in winter and rainy weather, where plants are prone to problems such as poor growth and distorted color of flowers and leaves. Plant growth lights can help plants grow and develop by providing spectra and light intensity that are suitable for their growth, promoting the production of flower buds and fruits, and improving the efficiency of plant photosynthesis. The spectrum of plant growth lamps mainly includes blue light, red light, and white light. Blue and red light are essential lights for plant growth. Blue light can promote plant growth and morphological development, while red light can promote the production of flower buds and fruits. White light can provide brightness and comfort, while also containing light of other wavelengths, which helps improve the efficiency of plant photosynthesis. There are various types of plant growth lamps, which can be divided into LED growth lamps, fluorescent growth lamps, metal halide growth lamps, etc. based on their different light sources. LED growth lamps are currently the most widely used type, gradually replacing traditional fluorescent lamps and metal halide lamps due to their advantages of energy conservation, long lifespan, and low chemical pollution. At the same time, LED growth lights can also adjust the spectrum and light intensity according to different plant needs to ensure the health and good growth of plants.

The dividend of the Lighting City is no longer: "It's like having a dream" Leaving the bustling shopping mall and trendy caf é center of Zhongshan, a 20 minute drive reveals the other side of the city: a large gray white small factory building with signs mostly reading 'XX Lighting'. The company operated by Yang Hong and Yang Chang brothers is located in Henglan Town. The company produces products ranging from LED packaging, lamp bead mounting, hardware stamping workshops to finished product assembly. Its main products are stamped outdoor commercial lighting fixtures, such as street lamps. The main market of the products is the surrounding countries of the "the Belt and Road". These regions are vigorously developing infrastructure and are more sensitive to price, but have low requirements for design and function, and need cost-effective products. Yang Hong was born in Macau and had a high paying job in a casino when he was young. At that time, I thought that even if I worked for another ten years, I wouldn't be able to afford a Ferrari. About ten years ago, he resigned from his job and returned to Zhongshan to take over his family's lighting factory. But when he really started being a boss, he still gave up the idea of buying a luxury car. Most of the money earned by the factory is used to buy automation equipment, which has already cost him tens of millions. Yang Hong laughed and said, "Porsche is parked in my workshop Yang Hong returned home just in time for the popularization of LED lights, and the tungsten filament and incandescent lights used in the past began to be replaced by more energy-efficient and efficient LED light sources. He recalled the grand occasion at that time, around 2015: "Switching to LED lights would immediately reduce the cost by 30%, and those who sold the lights would make money, and we would also have profits." He described it as a time when customers were everywhere, there were endless wine parties to attend, and a large number of people around him started businesses. He called on relatives and friends to become a company. During the golden period, a box of LED light beads was priced at 60000 to 70000 yuan. During holidays, when there was no one at home, the goods had to be stored in the safe at home. But the good days are not long, and with the market's popularity comes a price war. In order to maintain the competitiveness of the factory, Yang Hong had to spend all his money on updating equipment, "and all the millions he earned in a short period of time were spent on buying equipment LED lights are rapidly becoming popular, and the penetration rate of LED lighting products in China has grown from 32% in 2015 to 80% in 2021 in just six years. Product costs have rapidly declined in competition. For example, Yang Hong said that nowadays the price of a box of lamp beads is less than 1000 yuan, "it's like having a dream Price wars have always been a problem for local industries. The lighting industry in Zhongshan mainly produces mid to low-end lighting fixtures, with weak patent awareness and numerous early "copycat factories". The two brothers' company has reached a medium-sized scale, and the competition with their peers is still cost-effectiveness. It is difficult to crush through technology because there is not too high a threshold, "Yang Hong quipped." Perhaps the lowest end of technology in electronic products is lighting. We also use IC chips, just power on and light them up. The lowest end of the IC is for us to use Wen Qidong, Executive Vice President and Chief Researcher of Guangya Lighting Research Institute, also pointed out this issue: "The Zhongshan lighting industry chain is very comprehensive, not only a manufacturing center but also a commercial center, with scale advantages. However, although the scale is large, the enterprises are very small, with poor risk resistance and limited core competitiveness

The core technology of circular LED beads is the selection and manufacturing process of semiconductor materials and chemicals. In the manufacturing process, semiconductor material chips are first processed into LED chips through special processes, and then packaged with pearlite to form circular LED lamp beads. Due to the high light efficiency and controllability of circular LED beads, they can effectively increase manufacturing costs and reduce usage costs, while also reducing environmental pollution. Advantages of Circular LED Beads Compared with traditional lighting products, circular LED beads have significant advantages. One is energy conservation and environmental protection. The circular LED beads have high brightness and excellent light efficiency, which can significantly improve lighting efficiency, reducing the amount of electricity required under the same lighting conditions and thus reducing energy consumption. The second is its long lifespan, which can reach tens of thousands of hours or more. Not only does it save the cost of replacing the lamp beads, but it also saves the cost of maintenance. The third is usage safety. Circular LED beads do not contain mercury, do not generate ultraviolet and ultraviolet radiation, and do not pose any harm to human health and the environment. In addition, there are many other application scenarios for circular LED beads. For example, it can be used for outdoor lighting, such as roads, squares, parks, etc., as well as indoor lighting, such as shopping malls, supermarkets, office buildings, etc. Overall, circular LED beads, as a new type of lighting product, have won the favor of the market due to their advantages of high efficiency, low power consumption, and environmental protection. With the development of technology, circular LED beads will have more application scenarios and broader market prospects in this field.

The emergence of plant growth lights has completely solved the problem of planting plants indoors, providing a better environment for plant growth. The advantage of plant growth lights is not only that they can replace sunlight, but also that they can adjust the color and intensity of light according to different needs of plants, thereby promoting plant growth to the maximum extent possible. Moreover, the use of plant growth lights greatly saves planting costs and makes indoor planting more convenient for people. So, what are the advantages of using plant growth lights? Plant growth lamps can provide all the spectra of light required by plants, including blue light, red light, purple light, etc. These spectra are extremely important for plant growth. In natural environments, sunlight is filtered out due to factors such as clouds and atmosphere, resulting in imbalanced spectra received by plants. Using plant growth lamps can provide appropriate spectra according to the needs of plants, thereby promoting their growth. The use of plant growth lights can also adjust the intensity and duration of light, thereby improving the efficiency of plant photosynthesis and promoting plant growth. In natural environments, plants can only adjust the rate of photosynthesis based on the intensity and time of sunlight, while using plant growth lamps can adjust according to indoor light conditions, thereby better promoting plant growth. The use of plant growth lights can also control indoor temperature and humidity, thereby creating a more suitable environment for plant growth. In the natural environment, the growth of plants is limited by climate factors, and using plant growth lamps can create a more stable and suitable environment, thereby improving the growth efficiency of plants. Overall, the emergence of plant growth lights has completely changed the challenges of indoor planting and provided a more favorable environment for plant growth. The advantage of plant growth lights is not only that they replace sunlight, but also that they can adjust the color and intensity of light according to different needs of plants, thereby promoting plant growth to the maximum extent possible. Moreover, the use of plant growth lights can also save planting costs and make indoor planting more convenient for people. If you want to plant plants at home, then a plant growth lamp is yours.

The light strip is a seemingly inconspicuous lighting product, but if it is used reasonably in the space, it can well show the level sense of light, making the space environment more soft and emotional. Use "light" as an important element of "activated space" to make simple space no longer monotonous. What is the way to perfectly integrate the invisible light into the space? Let's start with the three most common ways! Ceiling design The light band is designed in the suspended ceiling to increase the sense of hierarchy on the top. The combination of light and dark, and the adjustment of color temperature, form one or more virtual reality contrast, dynamic and static effects. Cabinet design The light band is integrated into the cabinet, which can visually expand the sense of space, weaken the sense of closeness, and soft light will not create a sense of discord. In terms of practicality, it can serve as the lighting in the cabinet to prevent the dark inside the cabinet from affecting the use. Space decoration In addition to the use of light strips in the living room ceiling and other large court exhibitions, we can also create different light shapes on the walls of the living room and bedroom, stairs, hallways and other walls through the combination of light strips and space design, with personality reflected in details. Wufeng LED launched a bright light band with curved surface design and large angle light, making the light softer and creating your personality space instantly. Founded in 2006, Dongguan Wufeng Electronics Co., Ltd. has been focusing on the professional development of LED cabinets and local lighting of display cabinets, and is committed to achieving the perfect combination of local lighting and furniture. The main products are cabinet lamp, spot lamp, cabinet bottom lamp, cabinet interior lamp, laminate lamp, furniture lamp, clothes pole lamp, LED soft/hard light strip, shelf lamp, drive power supply, inductive switch, etc. To provide you with the best lighting solutions!

This more efficient light source is inspired by the discovery of serrated scales inside fireflies, which enhance the luminous effect of this creature. The cover on the LED lamp simulates the function of the scale and reduces the energy required by the LED lamp. The photosensitive material coating on the LED lamp simulates the function of firefly scales, improves energy efficiency and reduces the energy required for lighting. "The most important aspect of this research is that it shows how much we can learn by carefully observing nature," said Annik Bey, a Ph.D. from Namur University in Belgium In fireflies, a certain amount of light is reflected back into the lantern by the cuticle of its shell. But in some fireflies, this reflection can be reduced due to the arrangement of serrated scales, which means that more light overflows and makes the fireflies look brighter. A layer of photosensitive material on the LED lamp simulates the function of scales like fireflies, which not only improves energy efficiency but also reduces the energy required for lighting. "We refer to the structure of the edge of the factory roof, because the top of the scale is convex and slightly inclined, which is a bit like the factory roof," said Annik Bay In addition, this energy efficient coating can be applied to current LED lamps as an additional benefit.

Since the luminous efficiency of a single LED cannot meet the requirements of the light intensity and uniformity of the surgical shadowless lamp, it is necessary to use multiple LEDs to form an array, which should be reasonably arranged and evenly distributed so that the light intensity of each target plane meets the requirements, so as to determine the number and distribution rules of LEDs. Although LED has high luminous efficiency and generates less heat, so many LEDs in a sealed box will still generate a lot of heat, and the temperature will even reach 60 ℃~80 ℃. Therefore, the radiator and heat dissipation channel must be reasonably designed to effectively reduce the thermal resistance of the system. LED surgical shadowless lamp is composed of multiple lamp caps, in petal shape, fixed on the balance arm suspension system, with stable positioning, vertical or circular movement, and can meet the needs of different heights and angles during surgery. The whole shadowless lamp has 144 high brightness white LEDs, 8 of which are connected in series to form a group, which is called high brightness light-emitting diode (HBLEDs), and is composed of 18 groups in parallel. Each group is independent of each other. If one group is damaged, the others can continue to work, so it has little impact on the operation. Each group is independently driven by a LM3402 with constant current, and is controlled by a microprocessor (CMU) P89LPC932 with PWM pulse width adjustment, which can be steplessly adjusted. The current flowing through each LED is about 120~320 mA.

(1) Excellent cold light effect: The new LED cold light source is used as the surgical lighting, which is a real cold light source. There is almost no temperature rise in the doctor's head and wound area. (2) Good light quality: white LED has the chromaticity characteristics different from the shadowless lamp light source used in ordinary surgery, which can increase the color difference between blood and other tissues and organs of the human body, making the vision of medical students clearer in surgery, and making it easier to distinguish various tissues and organs of the human body in flowing and penetrating blood, which is not available in the shadowless lamp used in ordinary surgery. (3) Brightness stepless adjustment: Digital stepless adjustment and control of LED brightness is adopted. The operator can adjust the brightness at will according to his own adaptability to the brightness, so as to achieve the most ideal comfort and make the eyes working for a long time not easy to feel tired. (4) No stroboscopic: because the LED shadowless lamp is powered by pure DC, no stroboscopic, it is not easy to cause fatigue to the eyes, nor will it cause harmonic interference to other equipment in the working area. (5) Uniform illumination: a special optical system is used to irradiate the observed object 360 ° uniformly, with no virtual shadow and high definition. (6) Long life: The average life of LED shadowless lamp is long (35 000 h), which is much longer than that of circular energy-saving lamp (1500~2500 h), and more than ten times of that of energy-saving lamp. (7) Energy conservation and environmental protection: LED has high luminous efficiency, impact resistance, is not easy to break, and has no mercury pollution, and its light does not contain infrared and ultraviolet radiation pollution. The system is based on a high brightness white LED array, and a LM3402 controls a group of light emitting diodes. According to the set illuminance, the microprocessor P89LPC932 conducts constant current control through pulse width modulation.

1. Voltage, LED lamp beads use low-voltage power supply, and the power supply voltage is between 2 and 4V, which varies according to different products, so it is driven by a high-voltage power supply. Safer power supply, especially for public places. 2. Current, the working current is between 0 and 15 mA, and the brightness becomes brighter with the increase of the current. 3. Efficiency, energy consumption is reduced by 80% compared with incandescent lamps with the same luminous efficiency. 4. Applicability, very small, each unit LED chip is 3 to 5 mm square, so it can be prepared into various LED lamp bead shaped devices, and is suitable for variable environments. 5. Color, changing the current can change color. The light-emitting diode can easily adjust the energy band structure and band gap of the material through chemical modification methods to realize red, yellow, green, blue and orange multi-color luminescence. For example, an LED that is red when the current is small, can turn orange, yellow, and finally green as the current increases.

1. Lamp bead quality: 1. LED chip; Brands are commonly divided into three camps. The chip quality in the United States and Japan is good and the price is expensive, followed by * * *. The LED chip quality in China is poor and the price is low. The key of LED chips with different quality is their lifetime, which is determined by light attenuation. Small light attenuation, long life, long life and high price. The chip quality determines the brightness and light attenuation of the lamp bead. A good lamp bead not only has high luminous intensity, but also has low light attenuation. 2. Light efficiency: the higher the light efficiency, the higher the brightness of the lamp beads with the same power. With the same lighting brightness, the smaller the power consumption, the more energy-saving. The better the color temperature of the same batch of lamps is consistent, the higher the price is. 2. Drive power supply; LED lamps must be equipped with high quality and high efficiency driving power supply. The power factor of the driver shall be above 0.9. If the power factor is lower than 0.6, it belongs to unqualified products or garbage products, which not only has a short service life, but also the actual power consumption is about twice as high as the nominal value, with no power saving effect. At the same time, the current harmonic is also large, and the current is unstable, which is unfavorable to the life of the lamp bead and the overall lamp. The life of the power supply directly affects the overall life of the lamp. The theoretical life of the LED lamp bead is more than 50000 hours, while the life of the power supply is between 5000 hours and 30000 hours. It is impossible to guarantee the product quality and life of the LED lamp without a good driving power supply. 3. Heat dissipation conditions: 1. Radiator material; At present, most radiator materials are aluminum, the best is insert aluminum, the second is car aluminum (aluminum profiles, extruded aluminum), and the worst is cast aluminum. 2. Radiator structure: The contact area between LED lamp beads and aluminum substrate, aluminum shell, and the tightness of assembly will directly affect the core temperature conduction and heat dissipation effect of LED chips. 3. Radiator area; The size of the radiator area of the LED lamp determines the heat dissipation effect of the LED lamp. If the heat dissipation condition is not good and the lamp bead works under high temperature, the light attenuation will be great and the lamp life will be shortened. 4. Safety standards Some safety standards for LED lamps have been issued in China. Please select LED lamps according to the national safety standards. A high-quality LED lamp should also consider different use environments and different technical requirements, such as moisture-proof and dust-proof. In a word, a high-quality LED lamp requires a perfect combination of high-quality (chip) lamp beads, high-quality (chip) lamp beads, drive power, good heat dissipation conditions and safety standards! It cannot be regarded as a qualified product if only one party is emphasized. To this end, consumers should consider the above important aspects comprehensively when choosing LED lamps to avoid economic losses.

1. Quality of lamp beads: 1. LED chips; the commonly used brands are divided into three camps. The American and Japanese chips are of good quality and the price is more expensive, and the second is that the Chinese LED chips are of poor quality and the price is relatively low. The key to different quality LED chips is life, which is determined by light decay. Low light decay, long life, long life and high price. The quality of the chip determines the brightness and light decay of the lamp bead. Good lamp beads not only have high luminous flux, but also have small light decay. 2. Light efficiency: the same power lamp beads, the higher the light efficiency, the higher the brightness. The same lighting brightness, the smaller the power consumption, the more energy-saving. The better the color temperature of the same batch of lamps, the higher the price. 2. Drive power supply; LED lamps must be equipped with high-quality, high-efficiency drive power. The power factor of the drive is required to be above 0.9. If the power factor is lower than 0.6, it is a substandard product or a waste product. It not only has a short lifespan, but also the actual power consumption is about twice as high as the nominal one, so there is no power saving effect. At the same time, the current harmonics are also very large, and the current is unstable, which is detrimental to the life of the lamp bead and the life of the overall lamp. The life of the power supply directly affects the overall life of the lamp. The theoretical life of LED lamp beads is greater than 50,000 hours, while the life of the power supply is between 0.5 and 30,000 hours. It is impossible for LED lamps to guarantee product quality and life without a good driving power supply. 3. Heat dissipation conditions: 1. Radiator material: Now the radiator material generally uses the most aluminum, the best is the insert aluminum, the car aluminum (aluminum profile, extruded aluminum) is the second, and the worst is the cast aluminum. 2. Heat sink structure: The contact area between the LED lamp bead and the aluminum substrate and the aluminum shell, the tightness of the assembly, etc. will directly affect the conduction and heat dissipation effect of the core temperature of the LED chip. 3. Radiator area: The size of the radiator area of the LED lamp determines the heat dissipation effect of the LED lamp. If the heat dissipation conditions are not good, the lamp beads will work at high temperature, the light decay will be large, and the life of the lamp will be shortened. 4. Safety Standards Some of the safety standards for LED lamps in my country have been introduced. Please choose LED lamps according to the safety standards stipulated by the state. A good quality LED lamp also needs to consider different usage environments and different technical requirements, such as moisture-proof, dust-proof and so on.

Modern lamps can not only play an important role in lighting, but also play a role in home decoration. A must-have choice. 9. LED bulb light The bulb lamp is also very easy to understand. It is the incandescent lamp that everyone used in the home before. It has now been eliminated. There are two specifications, which are distinguished from the base. One is E27, and the E27 lamp head is the most commonly used screw lamp. There is also - one is E14, this kind of lamp head is relatively small, mainly used on candle lamps (I will not introduce all candle lamps for now, they are divided into bulb lamps, in fact, Zhang's battle is like a candle flame) 10. LEDI miner's lamp C miner's lamp is mainly used in industrial lighting. The size is small or large. The size of the large lampshade can be 1 meter or larger. The high bay lamp is a high-power lamp. 11. LED wall washer The name of this lamp is very artistic. It is mostly used for landscape lighting. It is a bit like a flood light. It means that the light is sprinkled on the wall, and it feels like the wall has been washed. It is mainly used for well-known or majestic buildings, such as bridges. , Museum Exterior Wall Lights. 12. LED street lights Street lights We all know that LED street lights are street lights made of LED lamp beads. 13. LED desk lamp LED desk lamps are mainly used for reading and writing. The color rendering index of this kind of lamp is generally required to be above 90, so don't think that bright is a good desk lamp, huh, color rendering index does not equal brightness. 14. LED lamp beads This is the most powerful and can be used in many places. Because the LED lamp beads are small, they can be made into various shapes and rich colors.

The design method of solar lawn light source and power system has developed rapidly in recent years due to the unique advantages of solar lawn light. The lawn lamp has low power and is mainly used for decoration purposes. It has high requirements for mobility, difficult circuit laying, and high waterproof requirements. These make lawn lights powered by solar cells show many unprecedented advantages. 1. Definition of LED solar lawn light Solar lawn lights mainly use the energy of solar cells to work. When the sun shines on the solar cells during the day, the light energy is converted into electrical energy and stored in the battery, and then the battery is used for the LED (light emitting diode) of the lawn lamp at night. ) to provide power. Its advantages are mainly safety, energy saving, convenience, environmental protection and so on. It is suitable for green grass beautification lighting decoration in residential communities, and park lawn beautification decoration. 2. The structure of LED solar lawn light It consists of solar cell components (photoelectric panels), super bright LED lights (light source), maintenance-free rechargeable batteries, automatic control circuits, lamps, etc. 3. System composition of LED solar lawn light The solar lawn light booster IC can automatically switch between charging and discharging behavior. When the solar charging panel senses sunlight during the day, it will automatically switch to turn off the light and enter the charging state. When the night falls, the solar charging panel will not sense sunlight. To enter the battery discharge state to turn on the light. The solar lawn light boost IC can boost the output voltage of a 1.5 volt rechargeable battery to 3.6 volts. A set of circuit board IC should be equipped with a No. 5 rechargeable battery to drive 1-7 LED light-emitting diodes; multiple sets of circuit board ICs and so on; the integrated circuit of the solar lawn light controller and some peripheral components, the main functions Including charging circuit, driving circuit, photosensitive control circuit and pulse width modulation circuit, etc. The controller has high conversion efficiency: 80~85% (typical value), which can reduce the power requirements of solar cell plates; low start-up voltage: 0.9V (maximum value); adjustable output current and other characteristics. 4. The light source advantages of LED solar lawn lights At present, most lawn lamps use LED as the light source. The LED has a long lifespan, which can reach more than 100,000 hours, and has a low operating voltage, which is very suitable for use in solar lawn lamps. In particular, LED technology has experienced its key breakthrough, and its characteristics have greatly improved in the past 5 years, and its performance-to-price ratio has also greatly improved. In addition, the LED is powered by low-voltage DC, and its light source control cost is low, making it possible to adjust the light and shade and frequent switching, and it will not adversely affect the performance of the LED. It can also easily control the color, change the distribution of light, and create a dynamic illusion, so it is especially suitable for solar lawn lights.

Underwater LED light bar is a kind of lighting fixture used underwater that takes into account the role of lighting and landscape. With the decoration of light bar, the night scene of the scenic spot at night is also a beautiful scenery line. The sealing performance or waterproof performance of the light bar is very important if it is used underwater. If it is not waterproof, it will lead to short circuit, leakage and other dangers, which is very bad, Therefore, some lamp strip manufacturers will choose to conduct LED lamp strip sealing and waterproof test on such underwater lamp strips to verify whether the waterproof grade or sealing performance of the lamp strips meet the requirements. How can the underwater LED lamp strip waterproof test detect the sealing? The indirect test method is used for the sealing and waterproof test of the underwater light bar. The LED light bar waterproof test mold is designed according to the shape of the light bar. Because the light bar is long, the sliding table type upper and lower closed mold is used. Put the light bar into the mold and press the start key, and the lower mold can slide to the predetermined position. The upper mold is pressed down and the lower mold is closed to seal the light bar as a whole. Then set the test parameters of the underwater LED strip waterproof test equipment (test pressure, inflation time, pressure stabilization time, test time, upper limit of leakage and other parameters). The underwater LED light strip waterproof test equipment detects and gives the results through the process of inflation, pressure stabilization and testing. Goel air tightness waterproof tester has high detection efficiency and simple operation. It can accurately test the sealing performance of LED light strips and improve the service life of LED light strips.
