High-power LED lighting application system settled in Tianjin University of Technology


On September 15th, Academician of Chinese Academy of Sciences, Professor Xue Qikun of Tsinghua University, Professor Zhang Guoyi of Peking University, Professor Ma Jian of Tianjin University, Professor Chen Hongda of Institute of Semiconductors of Chinese Academy of Sciences, Professor Luo Yi of Tsinghua University, Professor Chen Xiaoshuang of Shanghai Institute of Technical Physics, and Prof. Chen Hong of Institute of Physics, Chinese Academy of Sciences Tianjin Auto Lighting Factory Huang Chunwei Gaogong and other experts gathered at Tianjin Polytechnic University and listened carefully to Niu Pingjuan, director of the Engineering Research Center, on the feasibility study of the construction of the Engineering Research Center. He conducted a question and on-site inspection of Tianjin University of Technology "High Power Semiconductor". The construction project of the Lighting Application System Engineering Research Center of the Ministry of Education gave affirmation and support. The project is considered to be of great significance and can be closely integrated with national energy conservation and emission reduction requirements and social and economic development needs, in line with national energy conservation and environmental protection policies and regional industrial technology development.

In recent years, Tianjin University of Technology has made remarkable achievements in semiconductor lighting application system integration research. The school's semiconductor lighting engineering R&D center uses innovative computerized quantitative simulation and simulation thermal design technology, and circuit-level thermal management technology for high-power LED intensive applications. The secondary optical design technology with high light efficiency, high efficiency, low cost, long life single high power constant current driving power supply and other technologies have developed a series of modular high power LED street lamps and other international advanced standards.

They developed five high-performance, low-energy, intelligent "green lighting" products and industrialized implementation, which has been well received by domestic and foreign counterparts. The center's total investment of 100 million yuan of epitaxial wafer power chip industrialization project and the total investment of 220 million yuan of high-end semiconductor lighting products industrialization project was listed as the implementation plan of 20 independent innovation industrialization projects in Tianjin.

In recent years, the center's scientific research personnel have hosted and participated in more than 10 high-level vertical projects including the national “863” plan, the National Natural Science Foundation key project, the Tianjin Science and Technology Innovation Special Fund Project, and the Tianjin Science and Technology Support Key Project. A number of publications, 121 papers, 34 patent applications.

While paying attention to technology research and development, Tianjin Polytechnic University is actively pursuing the innovation path of production, research and development. In 2007, the school established the Tianjin High Power Semiconductor Lighting Engineering Center relying on the Semiconductor Lighting Engineering R&D Center. It actively led the development of semiconductor lighting engineering and industry in Tianjin with an innovative industry-university research platform, and established a national semiconductor lighting pilot city for Tianjin. Various advantages.

In April 2008, the school also invested in corporate funds to form Tianjin Gonghaiyu Semiconductor Lighting Co., Ltd., which is a high-tech enterprise integrating R&D, production and sales of high-end LED lighting products. In November 2008, the school led the establishment of the Tianjin LED R&D and Industry Alliance, bringing together industry peers to form the integrated benefits of LED R&D and industrialization, and building a green and environmentally friendly lighting industry chain with independent innovation capabilities. It was the establishment of the alliance that officially approved Tianjin in 2009 as an important supporting role for the pilot city of the national “Ten Cities and Ten Thousands” semiconductor lighting application project.

Niu Pingjuan, director of the Engineering Research Center of the Ministry of Education of the High Power Semiconductor Lighting Application System and professor of Tianjin University of Technology, said: "The development and industrialization of ultra-high brightness LED epitaxial wafers and power chips and high-end semiconductor lighting products development and industrialization projects belong to the international In the high-tech industry field of 'green lighting', the products have broad market application prospects."

High-power semiconductor lighting application system Engineering Research Center of the Ministry of Education is a platform for technological innovation, technology integration and results transformation integrating R&D, engineering and industrialization. Its establishment will promote the development of semiconductor lighting industry in Tianjin and even the whole country. Energy conservation and emission reduction, promoting the formation of a circular economy industrial chain such as new energy, and accelerating the construction of a resource-saving and environment-friendly society play an important role.
