China's largest commercial sapphire crystal LED in Anhui, Hefei

From June 14th, Hefei Luyang Industrial Zone, came the good news, Hefei Jingqiao photoelectric material Co Ltd first LED commercial successful trial production in Anhui Hefei sapphire crystal Luyang Industrial Zone, which marks the development of LED and photovoltaic industry in Hefei city in the process of sapphire substrate should start a new era for localization.

At noon on June 13th 13:30, a crucible of sapphire crystal descended from long crystal furnace, crystal photoelectric bridge technology personnel like a newborn baby will be carefully separated crystal weight and the crucible, a glittering and translucent sapphire crystal huge mound in front of people. The present expert detection, the grain weight height of 460 mm, 270 mm in diameter, weighing about 93.5 kg, transparent, no bubbles, no inclusions, growth pattern, combined with the analysis of the production process, initially identified as a large size sapphire crystal, can produce about 4000 mm equivalent 2 inch LED wafer sapphire crystal rod.

In June 14th, held a workshop of Hefei Jingqiao photoelectric material Co Ltd press conference, vice mayor of Anhui province by the deputy director Cao Xiaowu, deputy director of the Hefei Municipal People's Congress, the municipal government of Xie Gang Lu Shiren, municipal CPPCC Vice Chairman Yang Zhimao and other leaders attended the meeting and for the opening of Blaupunkt Shi Jing Xu, deputy general manager of Hefei rainbow blue limited company of science and technology Zhu Changrong to be congratulated and congratulatory. According to Dr Chen Jun responsible for the Crystal Bridge photoelectric company, the sapphire crystal in the country to create a domestic "three most": one is the largest, the crystal is by far the largest and most important commercial LED sapphire crystal; two is the most advanced technology, crystal photoelectric LED bridge into the United States K-1 sapphire crystal growth furnace the first, use the best growth method recognized improved kyropoulos method and technology, and seeding, automation and process control together with high quality KY crystal mature growth, so that the system can provide a high production efficiency; the three is the production of the fastest, the project was signed in January 15, 2011, from mid February this year, construction approach to May the equipment debugging, to produce the first grain weight, 4 months from scratch, creating a new record of scientific and technological achievements of the domestic high-end fast conversion.

According to the Hefei Luyang Industrial Zone, the person in charge, at the end of 2010, they heard a US company with LED sapphire crystal project site visits in a number of domestic city, one is Hefei, Luyang industrial zone immediately active and the project to introduce U.S. New Energy Company PowerSav contact, talk about policy, said advantage. In recent years, Hefei vigorously promote the development of photovoltaic industry and LED industry base, has become one of the fastest development of solar photovoltaic industry, has formed a relatively complete industrial chain; and the Luyang industrial area adjacent to the urban area and national new flat panel display industry base location, power plant and the railway freight yard North supporting advantage is an item of sapphire. Through sincere communication and enthusiastic service, Hefei Luyang Industrial Zone in the city and other domestic especially in Jiangxi city of Nanchang province "Sapphire battle" gradually prevail, in January 5th this year, mayor Wu Cunrong met with the United States PowerSav New Energy Company; then, in January 15th, the Provincial Committee and party secretary Sun Jinlong met with the United States and Hefei PowerSav New Energy Company Jing Ding Technology Investment Limited company responsible person, to encourage their development in Hefei. This strengthened the confidence of the project investors settled in Hefei, in the evening, the investor on the formation of Hefei bridge photoelectric material Co., Ltd. and Luyang Industrial Zone formally signed. Hefei, the "you do not want to go to the city," once again to retain the footsteps of distant guests.

According to the Crystal Bridge photoelectric technology personnel, sapphire crystal is the modern industry especially microelectronics, optoelectronics industry is an important material, is a new LED light source products in the upstream industry chain. Sapphire crystal is widely used in many fields, such as semiconductor, chemical industry, aviation, aerospace, national defense and so on. It has great social and economic benefits. Among them, large size sapphire crystal accords with the demands of global market trends, large size sapphire crystal can be made in accordance with the axial diameter of 2 inches, 4 inches, 6 inches of crystal, crystal by cutting, grinding and polishing a sapphire substrate for LED, but also can be used for military purposes. The small size of the sapphire crystal has also been used in the mirror surface, bearings, and parts of the instrument manufacturing.

Sapphire crystal the largest size of the successful birth of highlighting the growth in large size sapphire city technology have strong strength, also marks the city until the end product from R & D building a complete industrial chain gradually through LED. The general manager of Hefei Jingqiao photoelectric material Co Ltd Dr. Chen Jun said, the company plans to build two production base in 2012, by the end of 500 million yuan in sales; by 2015, will complete a total of three investment of about 1 billion 500 million yuan, 2 billion 600 million yuan in annual sales, then more than 20 billion yuan in the middle reaches of Korah LED extension, packaging and testing the development of industry, and even 300 billion yuan LED backlight module, automotive lighting, industrial lighting, general industry.
