Title
Useful lifetime analysis for high-power white LEDs.
Abstract
•The degradation-data-driven method is used to analyze the lifetime of HPWLEDs.•We present a bi-exponential model to improve the fit accuracy for the data.•The two-stage method provides the highest ability to explain variation.•A response model was used to predict the useful lifetime.
