On the new campus of Tianjin Polytechnic University, nearly 5,000 LED (semiconductor lighting) 60W or 80W lamps are scattered across the road, on the lawn and in the school building, 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 one of the largest semiconductor lighting demonstration projects 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. At the same time, this also heralds the rise of a new industry. At present, 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 key LED materials and terminal products to realize the key materials industry of semiconductor lighting per month. Turn.
Relying on Tianjin University of Technology, Tianjin organized 11 units including the Institute of Physics of the Chinese Academy of Sciences, Tianjin University, Tianjin Haibo Optoelectronics Technology Co., Ltd., etc., and established the Tianjin Semiconductor Lighting Engineering R&D Center for industry, university and research cooperation.
Focusing on major semiconductor lighting projects, the center has organized three special projects for science and technology innovation, namely the different stages of the LED mid-stream and downstream industrial chain, namely sapphire and gallium arsenide (upstream materials), epitaxy and chips (middle-stream products). Demonstration project (downstream terminal product application).
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 support from the state. The headlights include high beam, position lights and turn signals made with high-brightness LED light sources. The high beam has passed the national standard test of China Automotive Research Center.
The US technical team was also attracted to Tianjin to start a business, and formed the Safa company to develop and industrialize the sapphire substrate. The technical indicators of the products not only met the international standard of similar products, but also the accuracy of several main indicators such as flatness and orientation accuracy exceeded. The standard of international superior products. At present, a production line has been built, with a monthly production capacity of 5,000 pieces.
Another scientific research institution, the 46th Research Institute of China Light and Power Group, will realize the industrial production of gallium arsenide material preparation technology through the support of innovation specialization. In the second half of 2008, it will reach the scale of 30,000 pieces of gallium arsenide polished sheet, which is the largest in China. Manufacturer of GaAs 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. Realize annual sales income of 1.5 billion to 2 billion yuan.
