On application of heat-conductive plastics in LED technology

Abstract

A comparative analysis of the characteristics of heat-conducting plastic was performed. The results of the thermal measurements of two of the same type 3W LED modules installed on heat sink with the same area of heat-dissipating surface made of aluminum and heat-conducting polymer have been presented. It has been shown that the overheating of LED module mounted on the heat-conducting polymer heat sink is 2…3 °С higher than that on the aluminum heat sink (thermal conductivity is 20 times higher). The ranges of applicability of the heat-conducting plastics in LED technology have been determined.
