Abstract

The paper refers to modelling characteristics of power LEDs with thermal occurrences taken into account. The electrothermal model of the considered class of devices dedicated for SPICE is proposed. This model takes into account self-heating phenomena and the influence of temperature on their electrical and optical characteristics. The form of the worked out model is described and the results of verification of its correctness both for static and dynamic conditions are shown. At different cooling conditions the good agreement between the results of calculations and measurement is obtained.
