Our government is on the development of semiconductor lighting technology, in the end of 2003 emergency launched the national science and technology research plan: "semiconductor lighting industrialization technology development". Through the "15" and the "eleventh five-year plan" national semiconductor lighting project implementation, our country in LED extension materials, chip manufacturing, device sealing, phosphor and other aspects, were already appeared with independent technology property right unit technology, portions of the core technology with originality; Initially formed from the upstream material growth and chip preparation, middle device assembly and integrated application of downstream of the relatively complete development and industry system; Including LED large size back light, street light, canister light, automobile lamp of hundreds of new products developed in succession, realized the batch production; Large-scale system integration technology research and major application going smoothly, and successfully applied to the Olympic Games. The ministry of science and technology has approved Shanghai, xiamen, dalian, nanchang, shenzhen, yangzhou, shijiazhuang city seven semiconductor lighting engineering industrialization base, promote the regional
