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...
The phosphor-converted light emitting diodes (LEDs) are the most frequently used white light LED. Due to the Stoke's loss, the silicone/phosphor composites generate a considerable amount of heat. However, as a result of different sedimentation times or coating processes, the phosphor particles present different distributions in the silicone matrix, which has been proved to strongly influence the performance...
The effective thermal conductivity (ETC) of silicone matrix embedded with particulate phosphors is of great importance in the thermal management of white light-emitting diode (LED) packages, not only because the mixture provides the heat dissipation path but also because the phosphors may generate heat as well. In this paper, a 2D/3D unit cell method with considering interface resistance was proposed...
