Application of graphene sheet as intermediate heat spreading layer in LED modules
2016 13th IEEE International Conference on Solid-State and Integrated Circuit Technology (ICSICT)(2016)
摘要
Graphene exhibits an extremely high in-plane thermal conductivity, which shows highly prospective value in thermal management and heat spreader application. In this work, graphene sheet was integrated into LED module as intermediate heat spreader with different schemes, and heat dissipation performance was measured and evaluated using standard InfraRed (IR) camera. The experimental data shows that introduction of graphene sheet can reduce chip temperature, which can potentially increase the luminous efficiency and performance of LED products.
