Abstract


This paper discusses the heat effect on the junction temperature of light-emitting diodes (LEDs) of AlGaN. The junction temperature of AlGaN LED based on heat balance is analyzed and agrees with the available experimental data. The junction temperature decreases with the decreasing ambient temperature and the increasing the effective thermal conductivity and effective heat-conduction area.
