Color rendering and luminous efficacy analysis in YAG PC-LED by improved Gauss simulation

Gauss simulation is often used to help design new LEDs according to photometric and colorimetric performance requirements. This research investigates an improved Gauss simulation model for simulating YAG-PC LEDs. Three types of PC-LEDs are investigated at commonly used CCT ranges. This research shows that desirable photometric and colorimetric qualities can be achieved. For warm white, pure white and cold white CCT ranges, CRI of 72.1, 79.8 and 84.5 can be achieved, respectively. LEDs with optimal color rendering qualities are designed; packaging and measurement of said LEDs shows that the simulation model is successful.
