Abstract

This paper successfully establishes an optical model with dual green/red phosphor layers based on the original single-phosphor model. Since the re-absorption effect of double-layer phosphors causes spectral distortion, the model must introduce a correction mechanism for spectral re-absorption. Through the LED packaging experiment, simulation, and verification of the double-layer phosphors, we can effectively predict the ratios required for the two phosphors under different color temperatures and confirm this model's high precision and accuracy. In the future, this model can be used to analyze further the optical performance of white LEDs with different dual-layer phosphor packaging types.
