Degradation mechanisms of high-power white LEDs activated by current and temperature

► Analysis of the degradation of white LEDs, for different operating conditions. ► Two different types of state-of-the-art white LEDs were submitted to reliability tests. ► Full characterization of the degradation of the package at high temperatures. ► Analysis of the degradation of the package reflectivity, as a function of wavelength. ► First report of wavelength red-shift after high current stress.
