Electro-thermal modeling of power LED using COMSOL environment

Abstract

The aim of this paper is to build a dynamic thermal model of power LED for simulation environment COMSOL. The dynamic thermal model was based on technical and application manufacturer's data of power light emitting diode. In this way the assembled electrical and thermal model of power LED was simulated in a dynamic process of load within COMSOL simulation program. The simulation results have been subjected to verification in the real environment. Measurements of the real LED showed good agreement with the simulation results.
