| Abstract: | The graphene （GN）/thermal interface material （TIM） with silicone oil （SI） were made by graphene which has good thermal conductivity. Researched the material＇s properties, and used it in the thermal package of HB-LED lights, to study the thermal package effect of TIM, it was found that the TIM could reduce the interfacial thermal resistance of the device effectively, and improved the HB-LED＇s heat problem; and simulated HB-LED heat distribution by ANSYS software, which provided the basis for the improvement of LED packaging technology. |
