| Abstract: | Reasonable selection and efficient employment of packaging materials with high thermal conductivity are important for improving the reliability of high-power LED packaging. Based on the influences of systemic thermal resistance on LED performances, and comparison of traditional packaging materials, structural characteristics and thermal conductivity were introduced, including metal core printed circuit board, insulated metal substrates, ceramic substrates, thermal interface materials and metal matrix composites, various packaging application practices were described. In addition, the research emphases and problems to be solved at present of packaging materials are pointed out. |
