LED lighting prospects need to focus on core technology research and development

China Lighting Association Deputy Secretary General Liu Shiping believes that the lack of core technology is the bottleneck of the development of LED in china. Data show that, as of the end of last year, China has achieved LED related patents about 20 thousand, but the vast majority concentrated in the downstream applications, packaging and other fields. Due to the lack of core technology, the development of LED in our country is not balanced, the majority of enterprises are small in scale, low in technology and irrational in industrial structure. However, as the country attaches importance to the emerging industries and enterprises to strengthen the layout, is expected to promote the industry to further break the bottleneck to achieve new development.

The current global energy shortage fears rise again under the background of energy saving is an important problem that we face in the future, in the field of lighting, LED light-emitting products are attracting the world's attention, LED as a new type of green lighting products, is the future trend of development, twenty-first Century will enter a new lighting era as the representative of LED.

China's LED industry started in 1970s. After more than 30 years of development, China's LED industry has initially formed a complete industrial chain, including the production of LED epitaxial wafers, the preparation of LED chips, LED chip packaging and LED product applications. In the national semiconductor lighting project, driven by the formation of Shanghai, Dalian, Nanchang, Xiamen, Shenzhen, Yangzhou and Shijiazhuang, seven national semiconductor lighting engineering industrialization base. Yangtze River Delta, Pearl River Delta, Fujian Delta and the northern region has become a gathering place for the development of China's LED industry.

At present, the development of China's semiconductor lighting industry is good, especially the rapid development of epitaxial chip companies, packaging enterprises continue to maintain rapid growth in scale, lighting applications have made greater progress. The application of LED products in 2007 Chinese value has exceeded 30 billion yuan, has become a full-color LED display, solar LED landscape lighting application products the world's largest producer and exporter of semiconductor lighting industry is emerging. China has formed a certain characteristics in the field of lighting, which is the fastest development of outdoor lighting, there have been hundreds of LED street lamp enterprises and the construction of dozens of demonstration roads, but still lags behind in the general lighting market.

Recently, the city of Zhongshan LED industry and new achievement, by Zhongshan Hongbao Electric Co. developed the "single bead high power 30W combined LED lamp" project officially identified by the scientific and technological achievements, and has been identified in the field of semiconductor lighting, the overall technology products to the leading domestic level, the single bead high power 30WLED light source to achieve the application of the international advanced level in the street. It is reported that this project combines the thermal requirements of high-power LED light source, optical characteristics and driving characteristics of the system of LED street lamp key technology research and development, and achieved innovative results. In addition, the results of the product testing by the authority of the detection, the technical index and high-pressure sodium lamp street compared to energy-saving effect of more than 60%. At the same time, the relevant technology has applied for 15 patents, utility model patents and appearance patents of 6. This will undoubtedly bring China's LED lighting industry a booster.

However, although the domestic LED lighting industry is facing the trend of accelerated development, but still need to work hard in the core technology, in order to occupy the upper reaches of the core product status. Liu Shiping, Deputy Secretary General of China Lighting Association believes that the lack of core technology is one of the bottlenecks in the development of China's LED. Data show that, as of the end of last year, China has achieved LED related patents about 20 thousand, but the vast majority concentrated in the downstream applications, packaging and other fields. Due to the lack of core technology, the development of LED in our country is not balanced, the majority of enterprises are small in scale, low in technology and irrational in industrial structure.
