" Plant factory " has become a hot topic recently , but also to an environment which fosters the production of LED lighting products plant compelling . With the first generation of LED lighting overcapacity crisis , more and more companies are turning to Dongguan LED lighting fourth generation , the use of LED light source to create indoor plants like the sun , such as Mu growth environment .
LED light could simulate sunlight specific spectral component , which is already widely recognized academic study of plants . It is understood that in the plant kingdom , dominated by green plants , put the clock in all photosynthetic oxygen , chlorophyll leaves the body in the absorption of sunlight has two peaks , which are near the vicinity of 440 nanometers and 680 nanometers Blue Zone the red zone , one in the blue region , one in the purple area , and for the green light in the 500-600 nanometer absorption between small, so basically we see green plants .
Unlike incandescent lamps are LED chip emitting a single , can provide a specific spectral growth stage of the plant directly . Blue-ray wavelength of 440-490 nm , can promote the growth of green leaves ; 600-700 nm wavelength red light , helps prolong flowering and fruiting and flowering ; wavelengths between 300-440 nm violet and ultraviolet light , is to promote the formation of plant the main light pigmentation , and directly affect plants absorb phosphorus and aluminum elements and vitamin D, the formation of the stratum, as well as dry matter accumulation .
With LED lighting technology matures , LED light source and wavelength tunable lighting technology gradually into the biological field . Generally speaking , LED Grow Light Power ten watts or less , equivalent to tens or even hundreds of watts watt traditional fill light effect. Plus LED lights to save energy than traditional 90 % lighting biological field operating costs greatly reduced .
Not only that , LED also allows for the control of plant growth rate , flowering plants flowering can be extended , so that crops can be subject to seasonal restrictions and accelerate results. For example , plants can be carried out photosynthesis 16 hours a day , but the time is very limited natural light , making the plants grow slowly . If the use of LED lights , sustainable supplement to the plant light, LED light instead of using natural light and vegetables can reduce the third fastest growing maturity , yield can be achieved , the original 15 days ripe vegetables can be harvested as long as five days , which is LED light irradiation with plant growth promoting typical cases .
