dc.description.abstractIn this paper, the influence of scattering enhancement particles CaCO3, CaF2, SiO2 and TiO2, adding to YAG:Ce phosphor compounding, on color uniformity of white LEDs (W-LEDs) was presented. Firstly, the physical model of multi-chip W-LEDs is simulated and demonstrated by using commercial LightTools 8.1.0 program. After that, the influence of scattering enhancement particles on color uniformity is calculated and analyzed. With using the Monte Carlo simulation and the Mie-scattering theory, the color uniformity improvement of an 8500~K W-LEDs is demonstrated convincingly. From the researched results, the best color uniformity can be accomplished with TiO2 articles. The results and discussions provided a practical approach for higher-quality manufacturing W-LEDs.cs
