The way to solve the domestic LED plant lighting out of the predicament

The characteristic advantages of LED light source and the existing research foundations show that LED can be widely used in plant cultivation, greenhouse light supplement, plant tissue culture, plant factory, and is the key development direction of plant illumination light source in the future. China's LED plant lighting started late, still in the stage of R&D cooperation or demonstration and promotion. The competition pattern of the whole market is not obvious. There are only a few companies with absolute market advantages, and the market gap needs to be filled. In recent years, LED plant lighting system research has received strong support and capital investment from the national policy. The development space of the domestic LED plant lighting market is expected, but there are many problems. The author tries to analyze the main problems of domestic LED plant lighting and proposes Some suggested measures.

1. From the perspective of enterprises: marginal development strategy, lack of core competitiveness

At present, most domestic enterprises are still in the stage of observation and negotiation for the development of LED plant lighting, and no clear development plan has yet been formulated. Most of the enterprises mainly cooperate with scientific research institutions to carry out joint promotion of demonstration factories. Most of the related enterprises do not use LED plant lighting as the pillar product business of the enterprise, but small-scale trial production of LED plant lighting products based on other LED applications. . Based on this marginalization development strategy, domestic LED plant growth core technology and downstream sales channel construction and other aspects are insufficiently invested. Difficulties in core technology research and development, the core chips of most high-end products rely on imports, which greatly increases the cost of production. In addition, the LED lighting market still has problems such as product clutter, irregular production design, lack of uniform product standards and quality management.

Suggested measures: It is recommended that enterprises seize the opportunity to lay out LED plant lighting as soon as possible, and formulate long-term development strategies based on their own actual scientific planning; increase talent input, establish a fixed R&D team, actively learn and introduce R&D models and technologies of advanced national enterprises. At the same time, accelerate the research and development and innovation of independent core technologies.

2. From the perspective of R&D: The research and development model of “heavy LED and light biology” has not fundamentally changed.

The main force of research and development of led bio-lighting is mainly composed of led industry, materials and electric light source research and agricultural engineering circles. It lacks a deep understanding of plants and their cultivation principles. In practice, LED is the main body and there is no plant. The overall needs of the cultivation principle are considered comprehensively, and systematic research on the effects of light on animal physiology, ecology and behavior has not been carried out.

Suggested measures: First, it is recommended that the government set up a special research fund to guide and organize research on related topics. At the same time, it actively introduces and cultivates LED bio-lighting and comprehensive knowledge-based high-tech leading talents in biology, optoelectronics and technology. Demonstration and promotion for the company to popularize the correct research and development model and the introduction of composite-type professionals, truly transform the "heavy LED, light biology" research and development model. The second is to build a national and international public service platform, and cooperate with domestic and foreign research institutes, universities and lighting companies to conduct collaborative innovation research on LED plant lighting.

3. From the perspective of the state: insufficient financial support, imperfect industry standards and standards

Compared with foreign countries, the formulation of domestic policies and regulations is still in the initial stage. Although the "Twelfth Five-Year Plan" 863 Program "Intelligent Plant Factory Production Technology Research" has developed a number of LED energy-saving light sources with complete independent intellectual property rights and their light environment intelligent control technology achievements, and also received certain financial subsidies, but not enough to support The entire LED plant lighting industry is developing. In addition, the LED plant lighting product evaluation and measurement standard system is far from perfect: CSAS's "Performance Requirements for LED Panel Lights for Plant Growth" standard requirements are slightly thinner in terms of standard refinement and international integration.

Suggested countermeasures: It is recommended that the state continue to pay attention to and increase efforts to support the development of LED plant lighting industry, formulate special support policies for LED plant lighting, set up special industry support funds, and jointly research and promote LE plant lighting with private capital forces; actively learn from foreign LED lighting. The formulation of product technical standards, in line with international standards, will open up the channel to the international market as soon as possible.

4. From the perspective of consumers: science knowledge is not popular, traditional concepts have not changed

Compared with foreign countries, China's LED related technology research is relatively backward, and the knowledge of Chinese people's science is far from being popularized. At the same time, traditional concepts (for example, many people think that plants growing in the natural environment are healthier) are not familiar with the concept of plant factories, even There was hesitation, which led to the failure of the plant factory product market and the LED plant lighting product market to be fully opened.

Suggested measures: It is recommended that under the leadership of the government, enterprises should cooperate with the government to strengthen the promotion of relevant scientific and technological public opinion through various channels, for example, through mass media such as television networks to expand scientific propaganda, through conferences and lectures, and security demonstrations to guide changes in the concept of Chinese people.
