Future prospects and advantages of LED plant lights
With the development of LED technology, there are not only many LED plant factories abroad that can realize mass production of plants, but the Chinese market is also slowly emerging. As the world’s fourth largest plant factory, what is the prospect of China’s LED plant lighting market? In which direction will plant lighting develop? Aladdin News Center interviewed a number of senior industry experts and corporate executives for an in-depth interpretation and analysis. System explanation.
Plants in the greenhouse, if you want to grow well in winter, there is a necessary equipment for winter, that is-LED plant light. In the case of winter lighting time and light intensity are not enough, plant fill light can solve this problem well.
However, there are a lot of precautions when purchasing a plant supplement light. How to choose a suitable supplement light will have no effect as many people say. So in order to avoid this problem, we should pay attention to many problems when choosing plant supplement light.
Pay attention to the power of the fill light. The power of led plant fill light affects the intensity of light. Different plants have different requirements for light intensity, and light intensity affects the progress of plant photosynthesis under certain conditions. However, the power of many plant supplement light lamps is not accurate, and is completely inconsistent with the reported parameters, and the supplement light effect on plants will be greatly reduced. So when choosing LED plant supplement light, you can test the parameters first to see if it meets the requirements.
Pay attention to the spectral range of the fill light. We all know about supplementing light for plants. Plant photosynthesis absorbs the most red and blue light. When we choose LED plant supplement light, we choose the most red and blue LED plant supplement light. But when choosing, we should pay attention to the wavelength range of the light. The red light around 660nm and the blue light around 450-470nm have the most obvious effect on the plant.
Pay attention to the wavelength ratio of red and blue. Different plants have different requirements for the ratio of red and blue. When choosing, we should choose the ratio that has the best effect on plants according to the requirements.
The most suitable is the best. We have to choose the most suitable plant fill light according to the actual situation, and it will definitely have an effect.
Different wavelengths of light have different effects on plant photosynthesis. The light required for plant photosynthesis has a wavelength of about 400-700nm. 400-500nm (blue) light and 610-720nm (red) contribute the most to photosynthesis. Blue light helps plant photosynthesis and can promote the growth of green leaves, protein synthesis, and fruit formation; red light can promote the rapid growth of plant rhizomes, which is conducive to flowering and fruiting and prolonging the flowering period, which increases yield!
The characteristics of LED plant lights: rich wavelength types, just in line with the spectral range of plant photosynthesis and light morphology; spectral wave width and half-width narrow, can be combined as needed to obtain pure monochromatic light and composite spectrum; it can concentrate light of specific wavelengths evenly The ground irradiates the crops; it can not only adjust the flowering and fruiting of the crops, but also control the height of the plants and the nutrients of the plants; the system generates less heat and occupies a small space. It can be used in a multi-layer cultivation three-dimensional combination system to reduce heat Load and production space miniaturization industry.
Because of its remarkable characteristics, led is very suitable for plant cultivation in a controlled facility environment, such as plant tissue culture, facility gardening and factory seedling cultivation, and aerospace ecological life support system. As Yaorong's sixth-generation new lighting source, LED lamps have many characteristics that are different from other electric light sources, which also makes them the first choice for energy-saving and environmentally-friendly LED plant growth lamps. The LEDs used in the field of plant cultivation also exhibit the following characteristics: rich wavelength types, which coincide with the spectral range of plant photosynthesis and light morphology; the spectrum wave width is narrow at half width, and can be combined as needed to obtain pure monochromatic light and composite spectrum; it can be concentrated The light of a specific wavelength irradiates the crops uniformly; it can not only adjust the flowering and fruiting of the crops, but also control the plant height and the nutrient content of the plants; the system generates little heat and occupies a relatively small space. It can be used in a multi-layer cultivation three-dimensional combination system to achieve Reduce the heat load and miniaturize the production space; its strong durability will also reduce operating costs.
However, it is reported in the industry that the price of artificially cultivated vegetables using LED plant lights is several times more expensive than traditional sunlight-illuminated vegetables, and the early investment is too high and the investment cycle is long, which to a certain extent restricts the large-scale promotion of the market. The voice of "Limited Development of LED Plant Lighting Market" followed. By understanding the current status of the domestic LED plant lighting field, objectively analyzing its development prospects, trying to provide enterprises with the future development direction of LED plant lighting.
Judging from the current agricultural planting at home and abroad, soil pollution is becoming more and more serious, the degree of desertification is also expanding, and more and more people pay attention to food safety issues. Under the premise of these problems, LED Plant lamp lighting will solve some of the existing problems to a certain extent. LED plant lamp lighting can realize soilless cultivation, which can reduce the problems of soil destruction or poor soil resources in some areas, and can also change the current planar planting The way, three-dimensional planting can be realized, which will completely subvert the current agricultural planting method and will have epoch-making significance. LED plant light lighting will have more and greater development potential. Agriculture itself is a long-term work, and related technical research and experiments also require a certain period of time. This is an inevitable process.
Advantages of LED plant lights:
1. No standard power socket connectors for drivers or cooling fans are required.
2. Compared with other plant lighting, it can save 10%~20% of the electricity bill.
3. Compared with other ordinary lighting equipment, the LED plant light has a milder line and will not harm the seedling plants.
4. An environment with red and blue wavelengths is required for plant growth.
5. Blue light can promote plants to grow taller, and red light can make plants bloom and bear fruit.
