Samenvatting

In this work we determine the factors influencing the accuracy of modern light emitting diodes (LEDs) thermal transient measurements. The impacts of the secondary capacitive dome heat path heat and the parasitic heat generation on the cup walls due to the light reflection losses are analyzed in this paper. The results indicate the importance of considering both of these factors for accurate interpretation of the transient measurements results and calibration of linked finite element thermal models. The importance of the parasitic heat losses on the LEDs cup walls consideration is shown to be especially relevant for LEDs with high internal quantum efficiency (IQE).
