Abstract
Thermal feature is an important factor of LED. However, as an internal parameter, junction temperature cannot be measured easily. Based on the LED circuit model, which is an ideal diode and a resistor in series, a new model of LED junction temperature Tj is proposed in this paper. Parameters can be extracted from the oil bath experiments. In this way, junction temperature can be derived. The accuracy of the method is verified through the oil bath experiments and optical experiments.
