In recent years, it has also begun to introduce agricultural lighting applications. Plant factories that use LED light sources and environmental control characteristics have become niche markets that major factories are eager to enter in recent years, the combination of LED lighting will shorten the harvest period of crops, plants or flowers, and appropriate environmental control will not only prevent pests, but also avoid the use of pesticides or reduce the use of pesticides, thus checking food safety, it also increases the added value of agricultural products. The conceptual niche of plant factories will have the opportunity to bring new solutions to many agricultural problems such as narrow land, thick people and pollution. Recently, with the gradual maturity of LED lighting applications in public space and commercial space, plant factories have become a new market that European, American, Japanese and Taiwanese companies are actively rushing into, especially for Chinese local governments to adopt plant factories, as a strategy for its performance highlights, it has once again attracted factories to try and strive for local government subsidies. With the improvement of LED lighting application maturity, LED lighting has become an indispensable part of plant factories. Compared with traditional halogen lamps and fluorescent tubes, LED light sources are not only environmentally friendly, but also have the advantages of power saving, for users, the controllability of LED light source brings more advantages to agricultural planting. According to the observation of experts in the industry, the light quality and light quantity of LED light sources can be controlled, and LED light sources with different wavelengths can be matched for different varieties and planting types, the part of light quantity can also be supplemented with the length of sunshine. In addition, the effect of strengthening specific wavelengths cannot be underestimated. Compared with traditional light sources, LED can give full play to the advantages that different plants need different specific wavelengths to supplement energy. However, compared with sunlight, LED energy is naturally slightly inferior. However, due to the lack of sunlight at night, the supplement and strengthening of LED light sources is one of the reasons that can shorten the plant production period.
