Original Abstract

Paper presents the static model of the LED behaviour under specific operational conditions created in Simulink tool. This model can be used for different types of LEDs and it operates with commonly available data provided by the manufacturers. Verification of model validity has been performed with high-power white LEDs at two testing methods. First method is based on LED operation with constant supply current and with using of system enabling heatsink temperature regulation. Second method is performed for real conditions operation, ambient temperature is constant and LED control is performed by regulation of supply power. Simulation of multiple LED operation with single heatsink and simulation of LED operation at different ambient temperatures are performed and presented in the paper.
