Semiconductor lighting is recognized as the most promising high-efficiency lighting industry in various countries. It is called another revolution after the incandescent lamp and fluorescent lamp, and represents the future development direction of the world lighting industry. The promulgation of the "Opinions" marks that China's green lighting industry has ushered in unprecedented development opportunities under the government's strong support and broad market space.
Semiconductor lighting, also known as solid-state lighting, refers to illumination using solid-state lighting devices as light sources, including light-emitting diodes (LEDs) and organic light-emitting diodes (OLEDs). It has the characteristics of rapid development of technology, wide application fields, strong industrial driving and great potential for energy saving.
Hu Zhaoguang, vice president of the State Grid Energy Research Institute, pointed out that semiconductor lighting has three major advantages: First, energy saving. Under the same lighting brightness, LED lamps save 40% to 50% more energy than ordinary lamps, and the maintenance and repair costs are extremely high. Low, almost no maintenance costs are incurred within 3 to 5 years after installation and use; the second is environmental protection. The lamp does not contain harmful substances such as mercury and lead and harmful gases contained in ordinary energy-saving lamps currently on the market; Long, the average service life can reach 50,000 to 100,000 hours, which is 3 to 5 times that of ordinary lamps.
It is precisely because of these characteristics that semiconductor lighting is recognized as the most promising high-efficiency lighting industry in various countries. It is called another revolution after the illumination source of incandescent lamps and fluorescent lamps. It represents the future development direction of the world lighting industry, not only the current response. The international financial crisis and the important breakthrough to maintain stable and rapid economic development are also important ways to promote new technological revolutions, foster new industries, promote energy conservation and emission reduction, and respond to global climate change. From the perspective of long-term development, the world lighting industry is undergoing transformation. Many countries have proposed to eliminate incandescent lamps and promote energy-saving lamps, and to make the semiconductor lighting energy-saving industry a new economic growth point in the future.
In recent years, the semiconductor lighting industry has developed rapidly, and the annual growth rate of global output has remained above 20%. China has also initially formed a complete industrial chain, and has certain advantages in downstream integration applications. In 2008, the total output value of China's semiconductor lighting was nearly 70 billion yuan, of which the output value of chips was 1.9 billion yuan, the output value of packaging was 18.5 billion yuan, and the output value of applied products was 45 billion yuan.
China also attaches great importance to the role of semiconductor lighting. As early as the end of 2008, the Ministry of Science and Technology and the Ministry of Finance launched the “Ten Cities and Ten Thousand Cities†demonstration work, and plans to promote more than 300,000 LED municipal lighting in 10-20 cities by 2010. The "Opinions" further clarified the key development areas of China's semiconductor lighting energy-saving industry: First, technology and equipment. Support the development of key equipment and materials such as MOCVD equipment, new substrates, high-purity MO sources (metal organic sources); develop basic research and development of gallium nitride materials, OLED materials and devices; support basic theoretical research on semiconductor lighting applications, including photometry Learning, colorimetry, measurement, etc.; to overcome the key technologies of semiconductor lighting industrialization, including high-power chips and devices, drive circuits and standardized modules, system integration and application technologies.
The second is lighting products. Develop and promote alternative semiconductor lighting styling products with remarkable energy-saving effects such as incandescent lamps and tungsten halogen lamps; develop and promote functional semiconductor lighting styling products with high performance requirements and long lighting time, such as parking tunnels and roads; Dimensional liquid crystal display backlights, automotive lighting and other semiconductor lighting products with high growth potential; development of medical, agricultural and other special-purpose semiconductor lighting products.
The third is the service system. Improve the international level of semiconductor lighting product testing platform; support the establishment of public information services, interdisciplinary design ideas and talent training platform; encourage energy-saving diagnostics, consulting and evaluation, product promotion, publicity and training services; promote contract energy management, demand management, etc. A new mechanism for energy saving services.
The development of green lighting industry has broad prospects. However, there are still some problems in the development of semiconductor lighting in China, such as the lack of patents and core technologies, the low overall level of the industry, and the emergence of low-level blind investment. In order to support the timely and successful completion of these tasks, the "Opinions" proposed seven policy measures. The first is to make overall plans to promote the healthy and orderly development of the industry. Second, continue to increase the support for innovation in semiconductor lighting technology. The third is to steadily improve the development level of the semiconductor lighting industry. The fourth is to actively promote the development of semiconductor lighting standards, product testing and energy certification. The fifth is to actively implement incentive policies to promote the development of semiconductor lighting energy-saving industries. Sixth, extensive publicity and education on the lighting of semiconductor lighting and personnel training. The seventh is to strengthen regional and international exchanges and cooperation.
Hu Zhaoguang said that through the further implementation of these measures, China will vigorously implement green lighting projects, which will form a group of key enterprises with independent intellectual property rights, well-known brands and strong market competitiveness, and achieve key breakthroughs in technology and industrial priorities. Spanning, nurturing and revitalizing China's semiconductor lighting energy-saving industry, promoting energy conservation and emission reduction, and promoting steady and rapid economic development.
