In the new campus of Tianjin Polytechnic University, there are approximately 5,000 60-watt or 80-watt semiconductor lamps dotted all around the roads, lawns and dormitories. The university is enjoying its own achievements in scientific research. In the past one year and more, these energy-efficient lamps have saved up to one million yuan and it is also the world’s biggest-scale semiconductor illumination demonstration project.
These lamps are the research achievements by the joint effort of the university and Physics Institute of Chinese Academy of Sciences. For China, a country inflicted by an ever-increasing threat of energy shortage, seeking and promoting new energy-efficient technology are very promising in terms of market prospect. The situation also foretells the emergence of a new technology.
As a matter of fact, supported by Tianjin Polytechnic University, Tianjin has established Tianjin Development Center for Semi-conductor Illumination Project, which combines manufacturing, studying and researching, in association with 22 institutes including the Physics Institute of Chinese Academy of Sciences, Tianjin University and Tianjin Haibo Electro Optical Technology Co., Ltd. It has preliminarily completed the R&D at all levels and the industrial layout, improving the R&D of major materials for LED and final products, making possible the industrialization of the major materials for semi-conductor illumination with an output of 10,000 pieces per month.
Presently, Tianjin Haibo Electro Optical Technology Co., Ltd. is cooperating with Tianjin Polytechnic University to industrialize general semi-conductor lamps. Now they are capable of manufacturing 10,000 street lamps and 100,000 down lights every year. Their products have been used with many demonstration projects. This company also successfully developed the first LED car headlight independently in China, supported by the State. The headlight consists of the high-beam light, parking light and steering light adopting high-brightness LED illumination. The high-beam light has passed the State-standard test of China Automotive Technology & Research Center.
American technological research teams are also coming to Tianjin to set up a company to develop and industrialize sapphire substrate. The technological indexes of the product not only reach the international standards of products of its kind, but also surpass those of world renowned high-quality products in main areas of planeness, high precision in directioning and so on so forth. Presently an assembly line has been finished with monthly productivity of 5,000 pieces. It is the only enterprise in China which adopts independently-developed technology to produce gallium nitride substrate.
Another research institute, China Electronics Technology Corporation Research Institute No. 46, has realized the industrialization of the preparative technique for production of gallium arsenide materials. In the second half of 2008, the manufacturing scale for gallium arsenide polished pads reaches 30,000 per month and makes the company the biggest manufacturer of gallium arsenide substrate in China.
According to Tianjin Science Committee, through the combination of manufacturing, studying and researching, Tianjin will have semi-conductor illumination industrial cluster in the Binhai New Area and ultimately establish State-level R&D transformation center for semiconductor illumination. There will be five to ten competitive key enterprises with annual sale totaling 1.5 to 2 billion yuan.
