Abstract

The aim of this thesis is the reliability analysis of high-power RGB and white LEDs\nprovided by six different manufacturers. In order to evaluate the characteristics of these devices in terms of lifetime and optical power maintenance combined thermal and current stress tests have been carried out, verifying the changes of the optical and electrical characteristics of the devices during\nthe stress. The results of this work have revealed several types of degradation of various\ndevices.
