Analysis on the development dilemma of LED plant lighting in China

- Jul 23, 2019-

With the continuous development of modern agriculture, the demand and energy consumption of plant lighting are constantly expanding, which poses new challenges to the traditional plant lighting technology. LED as a new generation of light source, in addition to the characteristics of environmental protection and energy saving, compared with the traditional agricultural areas commonly used fluorescent or artificial light sources, such as high pressure sodium lamp has a light, light quality, and the adjustable, adjustable cooling load is low and allowed to improve the cultivation quantity per unit area, etc, to the closed loop control of the environment of agricultural production, such as plant tissue were is a very suitable for artificial light.

At present, the development of domestic plant lighting is slow, and the market development space is still limited. Domestic LED plant lighting is also facing problems such as lack of comprehensive talents, high cost investment, lack of patents and low production rate of enterprises. When the development of plant lighting in China will enter the fast lane is still a question.

Plant lighting as an emerging market, its market penetration rate is low, compared with hundreds of billions of ordinary lighting output value, can only be described as "small house see big house". At present, the domestic LED plant lamp sales market is mainly concentrated in Japan, South Korea, China, the United States, Europe and other countries and regions engaged in less agricultural personnel.

Although the potential of breeding lighting market is huge, this market has not been developed at present. Breeding lighting mainly USES LED fluorescent tubes, but the biggest difficulty in promotion is the change of cognition.

At present, the domestic LED plant lamp market is still in its infancy, and the lamps applied in the field of plant growth not only have high cost, light penetration and other problems. There are still some problems such as disorganized products, irregular production design, lack of unified product standards and quality management.

LED plant lighting technology is not very difficult, the key is the lack of understanding of biological training knowledge and LED technology comprehensive talents. LED plant lighting technology and production process, and general lighting no difference, the key is the choice of chip spectrum.

Although the chip technology related to plant lighting has been mature, different plants have different requirements for light exposure and different living environments, which requires enterprises to have a deeper understanding of different plant spectra, living conditions and cultivation environments, which is what many enterprises are confused about at present.

In view of the problem of talents, many large international factories, with the support of policies, choose to cooperate with scientific research institutions to set up laboratories or plant factories. But for domestic companies, the investment is too large and the cost too high. At present, the cooperation between some enterprises and agricultural research institutions is basically to discuss relevant technical issues, rarely involving the stage of experimental application. However, most small and medium-sized enterprises' investment in plant lighting is only limited to the independent research and development of a few plants, such as tomatoes and Chinese cabbage. They use LED lights to illuminate the relevant plants simply.

Domestic semiconductor chip epitaxial industry started late and accumulated little experience, and its patent strength in chip epitaxial is relatively weak. A large number of core patents are held in the hands of early leaders such as Japan, Japan and Corey in the United States, which greatly hinder the development of domestic chip enterprises.

Currently, LED plant lamp sales are concentrated in Japan, South Korea, Central America, Europe and other countries and regions with fewer agricultural personnel. With the continuous improvement of LED plant lighting technology in China, its production cost will gradually decrease and its penetration rate will gradually increase, and the Chinese market will enter the outbreak period. In general, whether from the perspective of promoting modern agricultural development or realizing energy conservation and environmental protection, LED application in agriculture is of great significance, and the status and development demand of agriculture also provide development opportunities for LED.
