With the maturity of plant growth supplementary lamp lighting technology, LED light source and wavelength adjustable technology have gradually entered the field of biological lighting. Generally speaking, the power of LED plant growth lamp is less than 10 watts, which is equivalent to the traditional supplementary light effect of tens or even hundreds of watts. In addition, LED saves more than 90% of the energy than traditional lamps, and the cost of lighting operation in the biological field is greatly reduced.
Moreover, LED can also control the growth rate of plants, prolong the flowering period of flowers and plants, and make cash crops free from seasonal restrictions and accelerate the results. For example, plants can photosynthesize for 16 hours a day, but natural light time is very limited, which makes plant growth slow. If the use of LED lights can continue to supplement light for plants, replacing natural light with LED light, the vegetable ripening period can be shortened by one third at the fastest, and the yield can be increased. The original 15-day mature vegetable can be harvested in only 5 days. This is a typical example of using LED light to promote plant growth.
The concept of plant factory is to turn vegetable greenhouse into factory workshop. Each workshop has different LED light. Soilless plants can move to different workshop to promote their growth according to the needs of different growing periods.
Urbanization construction or further development of the industry from the global market, LED plant lamp sales market mainly concentrated in Japan, South Korea, the United States, Europe and other countries and regions engaged in less agricultural personnel.
