In the new campus of Tianjin Polytechnic University, nearly 5,000 semiconductor 60W or 80W lamps are scattered throughout the roads, lawns, and school buildings, so that the university first enjoyed its own research results. In more than a year, these lamps have saved 1.8 million yuan. This is also the largest semiconductor lighting demonstration project in the world.
These luminaires were the result of a collaboration between the university and the Institute of Physics of the Chinese Academy of Sciences. For China, which is increasingly affected by energy shortages, the search for and promotion of new energy-saving technologies will have broad market prospects and also herald the rise of a new industry.
In fact, Tianjin has established a semiconductor lighting engineering development center in cooperation with industry, academia and research institutes, initially completed the research and development and industrial layout of LEDs in the middle and lower reaches of the LED, and increased the research and development of LED key materials and terminal products to achieve the 10,000-piece/month-scale semiconductor lighting key materials industry. Turn.
Relying on Tianjin University of Technology, Tianjin organized 11 units including the Institute of Physics of the Chinese Academy of Sciences, Tianjin University and Tianjin Haibo Optoelectronics Technology Co., Ltd., and established the Tianjin Semiconductor Lighting Engineering R&D Center in cooperation with industry, university and research institute.
At present, Haibo Optoelectronics Technology Co., Ltd. cooperates with Tianjin Polytechnic University to implement the industrialization of semiconductor general lighting fixtures, forming a production capacity of 10,000 street lamps and 100,000 downlights per year. In 2007, it has achieved sales of 26 million yuan, and its products are used in many demonstration projects in China.
The company also independently developed the first LED car headlights in China and received national support. The headlamps include high beam, position lights and turn signals made with high-brightness LED light sources. The light has passed the national standard test of the China Automotive Research Center.
The US technical team was also attracted to Tianjin to start a business, and established Safa Company to develop and industrialize sapphire substrates. The technical indicators of the products not only meet the international standards of similar products, but also the accuracy of several main indicators such as flatness and orientation accuracy exceeds The standard of international superior products. At present, a production line has been built, with a monthly production capacity of 5,000 pieces. It is currently the only enterprise in China that uses its own technology to produce GaN substrates.
Another research institute, the 46th Research Institute of China Light and Power Group, realized the industrial production of gallium arsenide material preparation technology through the support of innovation specialization. In the second half of 2008, it reached the scale of 30,000 pieces of gallium arsenide polished sheet, which became the largest in China. Manufacturer of gallium arsenide substrate materials.
According to the Tianjin Science and Technology Commission, through the combination of production, education and research, Tianjin will form a semiconductor lighting industry cluster in Binhai New Area, and finally build a national-level semiconductor lighting R&D and achievement transformation base, and cultivate 5 to 10 backbone enterprises with strong competitiveness. The annual sales income is 1.5 to 2 billion yuan.
