On March 20th, the 5th LED Industry Theme Summit Forum was successfully concluded at Dongli Lake Hotel in Dongli District, Tianjin. The forum was organized by domestic well-known industry research, media organization Gaogong LED and Tianjin Dongli District People's Government, Tianjin. The city's Science and Technology Committee co-hosted nearly 300 industry leaders from across the country to participate in the forum. Speakers include Zhang Youhui, Secretary of Tianjin Dongli District, Chen Yansheng, Chairman of China Lighting Association, and Guan Baiyu, Deputy Inspector of Electronic Information Department of Ministry of Industry and Information Technology. Senior executives from industry bodies and governments, as well as Tang Guoqing, general manager of CREE China Market, Dr. Zong Mingcheng, Director of Solid State Lighting Standardization, Philips Lighting Asia Pacific, Yang Lan, Senior Sales Manager of OSRAM, Sun Hui, GE Systems Engineering Manager, and other international giants. There are many representatives and investors of domestic LED business leaders. This forum attracted nearly 300 high-level representatives from 136 companies in the LED industry in 19 provinces, cities and regions.

The topics of this forum cover the hot topics of current LED industry such as market opportunities, technology trends, and ten cities: semiconductor lighting technology and market forecast, LED street light technology, EMC and patent risks and countermeasures, LED market in 2010 Features and competitive factors, etc., including LED technology and all aspects of the market. Such as: semiconductor lighting technology, market status and prospects; LED lighting and standardization; EMC opportunities and risks; LED street lamp structure and system design; LED corporate financing, listing issues to pay attention to, etc., experts at each meeting, all aspects of the LED industry A thorough and in-depth discussion took place.

Chen Hao, the chief engineer of Ningbo Liaoyuan Technology, brought the technical solutions of LED street lamps. Chen Haijun believes that white LED street lights can help improve road lighting safety. He believes that road lighting should not only consider central vision, but also the ability to detect peripheral targets. White LED street lights with short-wavelength blue light are more conducive to human eyes to detect surrounding objects. In his speech, he pointed out that in terms of street lamps, reducing the interface thermal resistance and reducing the air gap is the key. Due to the inherent flatness of the material surface, there are actually fine air pockets. Since the interface thermal resistance of the air is large, it is not conducive to heat diffusion, so the overall interface thermal resistance is greatly increased.
