led agriculture lighting industry

Since 1994, Japan has been trying to use LED as lighting source in plant factories. They gained success by combination of red LED whose wave length is 660nm and 5% blue LED to foster lettuce and rice in artificial plant factory. Since 1990s, all the nations in the world have been actively using LED as tissue culture light.


LED is commonly employed in greenhouse. It’s an inevitable environment control equipment especially for multi-span greenhouse. Now, the greenhouse square reached 2,835 million hectare in the world, among which China takes up move 60%. Artificial lighting is the most important application in agriculture. To adopt LED as artificial light for greenhouse can not only energy at an astonishing level, about 50-60% estimated, but also improve spectrum distribution, stimulate plant growth and increase quantity and quality, which is very promising. It is estimated that LED artificial light possesses favorable market outlook.


According to statistics, there are over 300 tissue culture enterprises whose annual production value is over 10 million seedling and more than 5000 small tissue culture workshops and laboratories. The total square of plant tissue culture is over 20 million square meters with the annual production value around 20 billion yuan. The research of LED in the field of tissue culture started early and the technology is relatively mature. With the further decline of LED cost, it’s possible to popularize LED tissue culture dedicated light in an all-round way. No matter to improve modern agriculture development or realize energy conservation environmental protection, it’s very important to apply LED in agriculture. Meanwhile, the status and development need of agriculture provide new opportunity for LED lighting.
