Subject: Automotive LED-Ceramic substrate in the LED package
2010-01-08


As noted above white LED's heat into electricity with an increase in intensity continued to rise, LED chip temperature rise will cause reduced light output, LED packaging structure and a review of the use of materials is very important. The past, the use of low thermal conductivity resin LED package, is considered one of the reasons affecting thermal properties, so in recent years, a gradual switch to high thermal conductivity ceramic, or metal with resin package structure. High-power LED chips, respectively, of commonly used include: LED chip size, and to improve the efficiency of light-emitting LED chips, high-efficiency packaging take-ray, as well as high current and so forth.
