Temperature Distribution on the Surface of LED Lamps

Abstract

In this work, new thermally conductive polymer materials (TCPMs) on the base of polymer/graphite composites for cooling system of LED lamps were developed. Heat sinks for LED lamps were fabricated and investigated. Thermal conductivity and thermal diffusivity for all TCPMs were investigated by thermal analyzers XFA 500 and THB 100. Infrared thermal imager was used to study the temperature distribution of the LED lamps. Experimental and numerical investigations have shown high efficiency of polymer/graphite heat sinks for LED lamps.
