Abstract:An integrated high-power LED using semiconductor refrigeration technology to dissipate heat is introduced, This semiconductor refrigeration encapsulation structure of highpower LED which is based on the principle of Peltier effect can not only cool the high-power integrated device apparatus, but also enable the apparatus to work properly in unfavorable environment such as high temperature and tremor. Thus the semiconductor can broaden the application field of LED and extend the validity of high-power LED at the same time. White-light LED packaged in this technology have stable luminescence, small attenuation and extended lifetime.
Keywords:high-power LED  semiconductor refrigeration  Peltier effect  heating dissipation  packaging structures
