一、The rise of LED lighting reform, the arrival of agitation
China's rapid growth is LED the first officially launched in 2003 national semiconductor lighting projects of urban traffic lights, large-scale displacement. In recent years, the government has LED the preferential policies promoting the rise of industry of shenzhen short years, more than 700 producers from rapid development LED to more than 2000 producers. In the "national semiconductor lighting engineering", China has initially formed LED industry including LED chips of preparation, production, LED extension LED chip packages and LED products including complete industrial applications. In Shenzhen, Nanjing and other major cities in response to build, fund-raising and led industrial park, and LED industry base related development planning. In 2005, automobile led lighting and led lights ZengChangDai led the second development, in this year, led semiconductor lighting domestic market sales reached 10 million 11.7 billion breakthrough, 2004 grew 49.0%. In 2008, the international financial crisis, when demand significantly reduced LED industry focused on the domestic market. Good policy also followed, December 2008 ministry put forward "ten million lamp" engineering. City In March 16th, the ministry of GaoXinSi 10 cities to 21. The city of the future will receive the assistance in public space, such as road, tunnel, parking places, service stations,installation LED lighting lamps and lanterns.
二、LED industrial structure and LED advantages disadvantages
In 1996, China began to implement "the green lighting project", In Xiamen, Shanghai, Shenzhen, Nanchang base industry formed semiconductor illumination. Yangtze river delta and pearl river delta, min triangle and north China LED industry has become the colony. Now the LED to form a complete industrial chain, and gather formed 4 large area, and large base of the industrial structure in the country. Now engaged in more than the number of industries led 5 million, more than 20 producers research institutions, enterprises about 4000 producers, And the innovation of technology, the advanced enterprise. In great demand pull down, LED a brighter industry.
三、The LED display industry is facing the risks
Technically, LED belongs to high-tech manufacturing technology and product not mature. Within the industry enterprises whether continuous improvement of production technology of LED directly important industry. Once the technology behind the international level, will lose too many market share and even losses in a vicious circle. China has set the standard, the LED illumination lamps only adhere to the traditional testing method to detect LED lamp, but there is essential difference between the two. In addition, the application of all standard also vary, cause enterprise trans-regional development market in a great deal of resistance. Industrial transfer of risk. About 80 percent of the encapsulation of Taiwan to the mainland, transfer and extension of new ethnics-people is rarely. China's industrial structure, inevitably will increase with the taiwan-owned enterprise competition, the mainland enterprises still disadvantage. Domestic enterprise of small scale, LED the entire industry resources scattered, not only caused by enterprises, individual imported from abroad the expensive chip, bargaining capability of low cost, high status. Current, especially in the field of core patent white, the key problem of thermal power leds, durable, high phosphor such patent has been to Europe, the United States, China, the suppression of monopoly industries. By the global financial crisis, the influence of the world to support led may abate, led the popular in western countries, and we may be less than expected. In LED extension, chip production, compared with the international advanced level, and the brightness of the general domestic chips, luminous efficiency, antistatic ability, ability and quality control level leakage still have a large gap, now our core chip imports from the United States needed, prices, cost pressure is too great.
