The "12th Five-Year Special Plan for the Development of Semiconductor Lighting Technology (Draft for Comment)" was released to accelerate the advancement of semiconductor lighting (LED) technology and industrial development. Recently, the Ministry of Science and Technology released the "12th Five-Year Special Plan for Semiconductor Lighting Technology Development (Request for Comments) Draft) (hereinafter referred to as "Planning"), it is proposed that by 2015, the scale of the semiconductor lighting industry will reach 500 billion yuan, and it is proposed to focus on cultivating 20 to 30 leading companies with core technologies, more independent intellectual property rights and independent brands. Enterprises, built 50 pilot cities for ten cities and ten thousand.
Rapid development of the semiconductor lighting industry In recent years, semiconductor lighting technology has developed rapidly, and is developing towards higher light efficiency, better light quality, lower cost, more reliability, more functions and wider application. At present, the international light-efficiency level of high-power white LED industrialization has reached 130lm/W, the laboratory light efficiency has reached 231lm/W; the low-power white LED laboratory light efficiency has reached 249lm/W. Although the semiconductor lighting technology innovation And the application innovation speed is much faster than expected, but compared with the theoretical light effect of 400Im/W, there is still huge room for development. Semiconductor lighting continues to generate new applications while rapidly developing technology. The focus of competition is on CaN-based LED epitaxial materials and chips, high-efficiency high-brightness and high-power LED devices, LED functional lighting products, and intelligent lighting systems and solutions. Innovative lighting applications and major equipment development such as MOCVD (metal organic chemical vapor deposition equipment).
At present, the global industry presents the three pillars of the United States, Japan and Europe, and the competition pattern of South Korea, China and Taiwan. The semiconductor lighting industry has become the direction of strategic shift of international large enterprises, the speed of industrial integration is accelerating, and the business model is constantly innovating. Driven by the continuous support of national R&D investment and market demand, China's semiconductor lighting technology innovation capability has also been rapidly improved. The gap between technological innovation and international level in the upstream of the industry chain has been gradually narrowed. The downstream lighting application is expected to achieve leapfrogging through system integration technology innovation. development of. Some industrialization technologies are close to the international advanced level. The power efficiency of power-type white LEDs exceeds 110Im/W, which is close to the international advanced level. The indication, display and medium-sized backlight industry have begun to take shape, the industry chain has become more and more complete, and the functional lighting energy-saving effect has already appeared. Standards development and testing capabilities have made great progress. At present, China has formulated and published 22 national standards and industry standards.
Despite the rapid development of the semiconductor lighting application market, there are still many technical problems that need to be solved urgently. It is urgent to carry out research and development of key technologies for high reliability and low cost industrialization for different application fields, and to seize the commanding heights of the next generation of core technologies. With the acceleration of urbanization, the consumption of lighting products will further increase, and the pressure of energy saving and emission reduction will increase. Therefore, it is urgent to apply new semiconductor lighting technologies and products.
In 2015, the scale of the industry reached 500 billion yuan. The plan proposes that by 2015, the semiconductor lighting industry will achieve key technological breakthroughs from basic research, cutting-edge technology, applied technology to demonstration and application of the entire innovation chain, and key production equipment and important raw materials will be made in China. Focus on the development of new healthy and environmentally friendly semiconductor lighting standardization and standardization products to achieve large-scale demonstration applications; establish a public R&D, testing and service platform with international advanced level; improve the policy and service environment for technological innovation and industrial development, and build A group of pilot demonstration cities and characteristic industrialization bases will cultivate leading enterprises with well-known brands to form an internationally competitive semiconductor lighting industry.
Specifically, on the technical goal, the luminous efficacy of industrialized white LED devices should reach the international advanced level (150~200lm/W), and the LED light source/light fixture achieves 130lm/w, organic light-emitting diode (OLED) lighting fixtures. The efficiency reaches 80lm/W, and silicon-based semiconductor lighting, innovative applications, intelligent lighting systems and solution development have reached the world's leading level, forming 300 core patents; on the product target, more than 80 chips are localized, large-scale MOCVD equipment, The key raw materials will be localized, and new, energy-saving, environmentally-friendly and sustainable development of standardized, standardized and systematic application products will be formed. The cost will be reduced to 1/5 in 2011. On the industrial target, the industrial scale will reach 500 billion yuan and cultivate 20~ 30 leading enterprises with core technology, more independent intellectual property rights and independent brands, supporting 40 to 50 innovative high-tech enterprises, and building 50 pilot cities with 10 cities and 10 million cities and 20 innovative and distinctive features. Industrialization base, improve the industrial chain, optimize the industrial structure, increase market share, and significantly enhance the international competitiveness of the semiconductor lighting industry; In addition, we must cultivate and introduce a group of academic leaders, innovation teams and technology entrepreneurs, establish an international and open national public technology research and development platform, improve China's semiconductor lighting standards, testing and certification systems, and play a strategic alliance of industrial technology innovation. The role of promoting the deep integration of production, education and research, and effectively guarantee the sustainable development of China's semiconductor lighting industry.
Strengthening technical research and optimizing the industrial environment In response to the above objectives, the "Planning" put forward specific measures and key tasks. First, strengthen basic research, solve some basic scientific problems of high-efficiency LED chips on wide-bandgap substrates, study the bound excitons under high-density carrier injection conditions and their composite mechanisms; explore communication modulation functions and LED lighting devices Mechanism of influence. The second is to strengthen research on cutting-edge technology. Breaking through the patent barrier of white LED, the light efficiency has reached the international advanced level; researching white LED preparation technology such as large-size si substrate, strengthening the research of new white light illumination technology such as single-chip white light, ultraviolet light-emitting diode (UV-LED) and OLED; Break through the high-efficiency, high-reliability, low-cost core device industrialization technology; improve the reliability of LED devices and systems; realize the localization of core equipment and key supporting raw materials, and improve the industrial manufacturing level and profitability. The third is to strengthen the application of technology research. With the goal of preempting the commanding heights of innovative applications, focusing on process innovation, system integration and solutions, we will develop high-quality, multi-functional innovative semiconductor lighting products and systems to achieve large-scale production; develop semiconductor lighting products with cost-effective advantages instead of Inefficient lighting products; innovative applications in the areas of office, commercial, industrial, agricultural, medical and intelligent information networks.
