Abstract

LED structure degradation has been analyzed for many years. The structure degradation can occur for many different mechanisms including dark-line defects (DLD), dark spot defects (DSD), metal diffusion and shorts. A very important property of optical devices is its light-emitting power. Damage mechanics is applied to manage the light-emitting property during service conditions. Results of this management are useful to predict the device lifetime and to know the theorical value of operating hours.
