A Practical Degradation Based Method to Predict Long-Term Moisture Incursion and Color Change in High Power LEDs

A Practical Degradation Based Method to Predict Long-Term Moisture Incursion and Color Change in High Power LEDs

The effect of relative humidity on LEDs and how the moisture incursion is associated to the color shift is studied. This paper proposes a different approach to describe the lumen degradation of LEDs due to the long-term effects of humidity. Using the lumen degradation data of different types of LEDs...
