About this document
LED Reliability and Degradation Analysis by nikitha is a document available to read on EtoBox.
The document discusses reliability in LEDs. It notes that LEDs experience gradual degradation over time rather than catastrophic failure like lasers. This degradation can be rapid, caused by defects in the active region, or slow, caused by homogeneous degradation from point defects or impurity migration. The optical output power decreases over time according to an exponential decay function involving a degradation rate that is temperature dependent. An example is given of an InGaAsP LED with a 1 eV activati
