How to solve the LED thermal (transfer)

U.S. Department of Energy (DOE) on the led lighting to make the following assessment: There is no other like the LED lighting technology can have such a big energy-saving potential and improve the quality of our built environment. As the led lighting's life is a function of junction temperature, so thermal management is essential for the performance of led lighting. California San Jose is located in the Philips Lumileds Lighting Application Technology Manager, Rudi Hechfellner, said: "So far heat management is a led lighting system design of the most important aspect. led lighting system manufacturers by seeking to optimize the radiator, efficient printed circuit boards, high thermal conductivity thermal design of shell and other advanced technology to deal with this challenge. As the thermal simulation prior to the establishment in the physical model, from the perspective of thermal evaluation of different design and optimization of system-level design, it highlights the growing role of thermal simulation. "
LED lighting appears
is an emerging solid state lighting technology that will fundamentally change in the future in the form of lighting. LED design at the beginning of power less than 50 mW. In the past decade, LED power has risen to 40 ~ 80lm/Watt. In addition to energy-efficient addition, LED service life and long. Depending on the manufacturer and type of the life of a white LED can be in the range of 6,000 ~ 50,000 hours, the more than 30,000 hours of fluorescence (light) tube and 2000-hour incandescent bulbs. In addition, LED may not use filters to produce monochroyoga matic light.
market analysis firm Yole Developpement, said: LED solid state lighting market revenue in 2007 will rise to 1 billion U.S. dollars in 2012 to 103 billion U.S. dollars. Yole is expected in 2012 high brightness and ultra-high brightness LED combined revenues will reach 4.45 billion U.S. dollars, which is 700 million 8 million in 2007 to 5.5 times. These solid-state light-emitting devices has become a different light source selection applications, these applications include traffic lights, cars and trucks, the internal and external lights, the screen display can be seen, small LCD back lighting and decorative lighting. The latest Isuppli report (Reference 1) shows that in some new places have gradually adopted the LED.
