Electrothermal model of a power LED for SPICE

Krzysztof Górecki

Abstract

SUMMARY In this paper an electrothermal model of the power LED dedicated for SPICE is proposed. In this model electrical, thermal and optical properties of the considered device are taken into account. The description of the model and some results of the experimental verification of this model are presented for two types of power LEDS: LXHL‐BW03 and LXHL‐LW3C produced by Lumileds. A good agreement between the results of measurements and calculations is obtained. Copyright © 2011 John Wiley & Sons, Ltd.
