Talking about LED plant light and its domestic market analysis
The sales markets of LED plant lights are concentrated in Japan, South Korea, China and the United States, Europe and other countries and regions with fewer agricultural personnel. With the continuous improvement of China's LED plant lighting technology, its production costs will gradually decrease, the penetration rate will gradually increase, and the Chinese market will enter an explosive period. Whether it is from the perspective of promoting the development of modern agriculture or from the perspective of achieving energy saving and environmental protection, the application of LED plant lights in agriculture is of great significance, and the status and development needs of agriculture also provide development opportunities for LED plant lights. . However, the road to popularization of LED plant lights in China is still very long.
Many domestic research institutes have only started or completed experiments on "the effect of different LED light qualities on plants" in recent years. The light quality of LED plant lights is determined by the chip, and the quality of the domestic chips used in the current LED plant lights is not good enough. You can only choose imported chip-encapsulated LED lamp beads to produce LED plant lights, which leads to the production of lamps. The cost is high. But because of its accurate light quality and can be adjusted by artificial combination, the photosynthetic radiation per unit power consumption is very high, the plant supplement light effect is very good, the operating cost is very low (super power saving) and many other advantages, it is deeply loved by agricultural research institutes all over the world. It is favored by such organizations as intelligent plant factories. However, some private workshops have joined the lighting manufacturing camp. These people do not understand agricultural technology, and have no product experimentation conditions. They do not consider safety issues. They just purchase components at random, and the prices of finished products are super cheap. This inferior and useless so-called "LED plant light" is disrupting the already difficult market environment. This problem is also the current situation facing the white light LED market. When choosing LED plant lights, you also need to keep your eyes open. Yaorong Technology is the best. The products are quality-guaranteed, branded, and reasonably priced products. Don't be greedy for cheap and suffer huge economic losses and safety accidents.
At present, the domestic manufacturers specializing in the production of LED plant growth lighting lamps are small in scale and few in number. They are highly concentrated in the Shenzhen area, and most of them are scattered among the manufacturers of functional lighting. Therefore, the peak 660 nanometer red light chip that is mainly required for agriculture cannot As a result, domestic chip epitaxial wafer manufacturers are unwilling to invest manpower and material resources to develop agricultural red light chips. And because the chip manufacturers of the international giants are superior to domestic manufacturers in terms of luminous efficiency and reliability, the product chips of LED plant lights in my country still mainly rely on imports.
At present, the domestic LED plant light market is now in its infancy. The lamps used in the field of plant growth not only have problems such as high cost and low light penetration. There are also problems such as product disorder, irregular production design, lack of uniform product standards and quality management.
The technical difficulty of LED plant lighting is not very difficult. The key is the lack of comprehensive talents who understand biology and LED technology. The technology and production process required for LED plant lighting are not very different from general lighting. The key is the choice of chip spectrum.
Although the related chip technology for plant lighting has matured, different plants have different requirements for light irradiation and different living environments. This requires companies to have a deeper understanding of different plant spectra, living conditions, and cultivation environments. And this is exactly what is plagued by many companies.
LED plant is a special kind of lamp, according to the law of plant growth, it must need sunlight, and LED plant lamp uses the principle of sunlight, and the lamp is a kind of plant lamp that replaces the sunlight to give the plant growth and development environment.
In traditional agricultural production, ordinary electric light sources are generally used to supplement the light and apply different covering materials and other agricultural technical measures, such as the use of monochromatic fluorescent lamps and colored plastic films to change the light environment to regulate the growth and development of plants in the facility cultivation environment. A large number of applications and studies of LED plant lights in plant facility cultivation environments show that LEDs can solve these problems and are particularly suitable for artificial light-controlled plant facility cultivation environments. LED plant lights adopt different measures to avoid problems of different degrees, such as lack of analysis of specific spectral components, resulting in impure light quality processing, inconsistent light intensity, close to or even lower than the light compensation point of plants , The efficiency of the illumination light source is low.
Plants rely on the energy of light for photosynthesis to grow, flower and produce fruits. However, due to the ever-changing climate changes and light changes in nature, plants cannot fully absorb the photosynthetic nutrients they need during different growth periods during different growth periods, which brings disadvantages to growth, especially in the seedling stage. . Scientific and reasonable artificial spectrum creates good absorption and reflection conditions for plant growth. The energy values of the blue light zone and the red light zone are very similar to the efficiency curve of plant photosynthesis (the efficiency is more significant for green plants), which is the best light source for plant growth.
Different plants have different requirements for the spectrum. For example, lettuce is red and blue 4:1, strawberry 5:1, general-purpose 8:1, some need to increase infrared and ultraviolet, but some factories do not understand all the spectra. We called any plant that its full spectrum was suitable for, but because it contained ultraviolet light, the orchid was irradiated by others. Fortunately, it was not a very expensive one. White light contains all the spectrum, so someone designed a white LED plant growth light, which is full spectrum. Philips also did this stupid thing. And I did an experiment. The same plant uses two 200w white lights on one side, and a 90w UFO (red and blue 1:1) and a 90w square (red and blue 8:1) on the other. A week later, under the white light The plants grow slower than those with red and blue lights. Don’t be superstitious about white light. At most, add a few white LEDs to the red and blue lights for improvement, not as the main light. The output lumens of the LED itself is not very high. Some customers say that Philips’s is useless, because these Philips T-tube lamps have a maximum of 20w, and a frosted lampshade is added, which loses part of the lumens. How many micromoles can be left from the light shining on the plants when hung up high? LED plant lights below 50 watts are very suitable for use near plants, more suitable for plant tissue culture (layered planting), family flower and vegetable growing, small space soilless cultivation and other fields, while LED plant lights above 50 watts are very suitable For greenhouse use, it is better to keep the lights within 2.5 meters from the main crop canopy area.
After application test, the wavelength of LED plant light is very suitable for plant growth, flowering and fruiting. Generally, indoor plants and flowers will grow worse and worse with time. The main reason is the lack of sunlight. The illumination of LED plant growth lamps suitable for the required spectrum of plants can not only promote their growth, but also prolong their flowering period. , Improve the quality of flowers. The application of this high-efficiency light source system to agricultural production such as greenhouses and greenhouses, on the one hand, can solve the shortcomings of insufficient sunlight leading to the decrease in the taste of tomatoes, cucumbers and other greenhouse vegetables, and on the other hand, it can also make winter solanum vegetables It will be listed before or after the Spring Festival in advance, so as to achieve the purpose of off-season cultivation.
LED plant light is the latest high-tech product that applies scientific research results to agricultural production. It uses semiconductor LED lighting technology to combine light sources of certain wavelengths and colors to control the growth process of plants such as flowers and vegetables, so as to achieve the effect of increasing crop productivity, changing the flowering period, and improving the quality of agricultural products. It is a very practical and indispensable lighting product in current high-tech agricultural production.
