LED how to jump off the concept of heat to achieve industrial development

LED lighting is known as green lighting in twenty-first Century the most promising, LED lighting industry as a strategic emerging industry, can promoting the upgrading of traditional industries, attracted world wide attention, the United States and Europe and other countries and regions have to actively implement the development plan of semiconductor lighting, LED lighting industry layout stepped up.

LED from concept to discipline

"In the past few years, China's LED hot, just the concept of heat, rather than innovation hot, R & D heat. Due to the lack of core technology and patents, the low level of blind investment serious. 70% of the enterprises in our country can only be confined to the lower reaches of the low threshold of low technical content of the packaging and assembly links, the low level of competition. Chinese Academy of Engineering Zhou Lian said.

A few years ago, in China, some research institutions and enterprises lighting experts, for ultra high brightness LED epitaxial wafer and chip power development and industrialization and high-end semiconductor lighting, is a concept of "". After all, it is the international 'green lighting' cutting-edge technology.

Compared with the traditional lighting products, the utility model has the advantages of low energy consumption, long service life, high light efficiency, and the utility model has the advantages of no mercury, no flicker, energy saving, environmental protection, low energy consumption and long life, and the utility model has the advantages that the traditional lighting can not be compared.

Director of research center of Chinese Academy of Sciences, semiconductor lighting semiconductor lighting joint innovation country laboratory director Li Jinmin said, as a new generation of light source, LED lighting will be human after Edison invented the incandescent light bulb, one of the greatest inventions in the lighting field.

National semiconductor lighting engineering research and Industry Alliance Secretary General Wu Ling said, because of the specific LED lighting has many advantages, in June 2003, by the State Ministry of science and technology led the establishment of "national semiconductor lighting project coordination leading group", was a prelude to the domestic LED lighting industry. In early 2009, the Ministry of science and technology to carry out the Ten City million light semiconductor lighting application engineering pilot work, set off the development of domestic LED road lamps. October 2009, for the development of domestic LED lighting process, the national development and Reform Commission jointly organized by the Ministry of housing and other six ministries issued LED lighting energy industry development advice, clear the development goals of China's LED lighting industry in 2015. February 2013, to guide the healthy and orderly development of semiconductor lighting industry, to promote energy conservation, the national development and Reform Commission and other six ministries in the preparation of the "planning" semiconductor lighting energy industry, put forward the development target, LED lighting energy industry to 2015, tasks and measures.

As a result of national policy support, some domestic enterprises blind expansion, but the core technology research and development has not been a breakthrough. According to Li Xuemin, chief scientist of the Lehigh University, Veeco, researcher at the center for semiconductor memories, vice president of Taiyuan University of Technology Professor Xu bingshe traveled to the United States, and to explore the development of the core technology of LED, after returning home, with the winners of national outstanding youth fund Dr. Xu bingshe based new materials engineering technology research center was established, the industry's top experts and famous enterprises high school and University researchers have joined, forming a domestic LED technology field the most professional and most comprehensive research and development team. A number of well-known institutions of higher learning, scientific research institutes, have carried out the research and development of LED.

From the construction of disciplines to the invention patent of intellectual property

Three flow companies selling coolies, second rate companies to sell products, first-class enterprises to sell patents, super class enterprises to sell standards. Through several years of painstaking research, China's LED industry and the basic formation of applications.

With the core patent technology breakthrough and integration of Taiyuan University of Technology, China's main high-end accessories for lighting system integration products no longer rely on imports, also breaking the monopoly of foreign advanced technology and patents in the field of semiconductor lighting, grasp the initiative in the semiconductor lighting industry in the world. High brightness blue, green LED epitaxial wafers and chips, was in 2004 by the state 4 ministries identified as the country's key new products, LED, LD epitaxial wafers and chips and other key products, to reach the international advanced level.
