Re-Absorption Effect Modeling for Dual-Layer Phosphor Package of White LEDs

IEEE Photonics Journal, 2021
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 ...
