DEVELOPMENT OF AN EFFICIENT OPTICAL MODEL FOR LEDS-BASED WHITE LIGHT SPECTRUM DESIGN APPLICATIONS

Abstract

We have developed an efficient optical model for simulating the white light spectrum design with high color performance. The optical model began with experimental data collection, simulation with the mathematical model using Gaussian functions, and verifying the similarity between simulation and experiment. In application, the model is applied to study the effect of red light on the optical properties of the generated white light spectrum. The obtained results indicate that the established model is helpful for the solid-state lighting application to fabricate a light source that can emit white light with high optical performance.
