摘要：

This paper discuses on the practical example the problem of thermal modelling of power LEDs used in luminaries. The proper determination of the thermal resistance is crucial for accurate computation of the device junction temperature, which determines the device operating parameters. here, this problem is illustrated based on the analysis of power LED heating curve measurements taken for various amount of power dissipated in the device, which is soldered to the substrate in different ways. For each case, a compact thermal model is generated employing the Network Identification by Deconvolution method.
