Abstract
In this paper, thermal performance of RGB white LED packages was optimized by thermal simulation using the Finite Volume method. A Monte Carlo photon simulation method was utilized for the analysis of optical performance of LED in quantitative terms. It was found that the distribution of RGB chips has great effect both on the thermal and optical performance of the RGB white LEDs. The tilted angle, material of the reflection cup, and the shape of encapsulant were found to be the key factors which determine the extraction efficiency of LED package. It is demonstrated that the combination of optical and thermal simulation provides a comprehensive optimization approach for a design of high efficient RGB white LED package.
