China has become the world's largest producer and exporter of lighting appliances, but last year China's lighting industry output value of about 160 billion yuan, exports 10 billion US dollars, accounting for only 18% of the global market, big but not strong to become a bottleneck. Today, the 4th China International Semiconductor Lighting Forum and Exhibition was held in Shanghai.
Liu Yanhua, deputy director of the Ministry of Science and Technology, said in his opening speech that semiconductor lighting is one of the important ways to achieve energy conservation and emission reduction. Building a strong scientific and technological support system to promote scientific innovation and technological progress is to improve energy efficiency and reduce pollution emissions. The important means is to achieve the fundamental guarantee of energy saving and emission reduction. At present, there are still many technologies for semiconductor lighting that are still immature. Technology development, mass production and market development require joint action by multidisciplinary, multi-industry and even social sectors.
Liu Yanhua said that since the 1990s, semiconductor lighting technology has been changing with each passing day. The rich color and digital controllability of LEDs (LEDs) will make streets, homes and leisure places more colorful and personalized. The longevity and high efficiency of LED will greatly reduce the power consumption of the whole society and reduce the severe pressure of environmental pollution; the combination of LED and solar cell will make distributed lighting energy supply possible, bringing light to remote and poor areas.
In order to seize the commanding heights of the emerging industries of semiconductor lighting and achieve leap-forward development, China's semiconductor lighting industry has received great attention and attention from the government, the scientific and technological community and the industry. As one of the national industrialization bases approved by the five Ministry of Science and Technology, Shanghai Industrialization Base has formed a semiconductor lighting industry cluster with Zhangjiang Hi-Tech Park as the core and Radiation Jiading, Songjiang, Yangpu, Putuo and Caohejing. As of 2006, Shanghai has 105 LED-related patents and won numerous scientific and technological achievements awards. It has also established more than 100 national, industry and internal standards for the optical industry.
