From a long-term point of view, the LED has a tendency to gradually replace traditional lighting light source, LED light source is becoming more and more widely used, agriculture lighting committee vice President and secretary general, Dr, researcher at the Chinese academy of agricultural sciences institute of agricultural environment and sustainable development wen-ke liu LED lighting are introduced respectively in the greenhouse fill light, edible fungus plants, plant factories, plant seed, livestock and aquaculture, and application in the field of pest control and so on.
Among them, the plant factory is a high-precision environmental control through the facility to achieve continuous production of annual crops, agricultural systems and efficient facilities, is the highest stage of Horticulture; can be used for vegetable, nursery stock （vegetable seedlings, rice, tobacco, etc.）， herbs, etc. scale production. According to Liu introduced, plant factories to improve production efficiency 40-108 times （Kozai, 2013）。 LED light on the contribution of plant factories, including energy-saving, multi-dimensional cultivation, the regulation of on-demand and other light environment. Currently, artificial light plant factory business operations increased year by year, more than 100 seats in Japan, China more than 30 seats.
LED application in plant transformation “, marketization of earth in LED lighting of agriculture as the most likely.After using plant seed source and control system, the raise the seed, greenhouse space utilization rate of 60%;Reduce energy consumption by more than 60%;Reduce maintenance costs by more than 80% of lamps and lanterns;Reduced pesticide use hormone;Improve the quality of the vegetables, Chinese medicine and so on many benefits.
Global LED lighting application of plant output from 2013 onwards, beginning to show rapid growth, preliminary statistics in 2014 amounted to $ 100 million, 2017 is expected to reach $ 500 million. With the global LED lighting penetration rate applied to enhance agriculture, the Chinese market is slowly emerging, future broad market prospects.
