碩士 === 國立中央大學 === 光電科學與工程學系 === 102 === In this thesis, we have developed an optical model of YAG phosphor with mixing ZrO2 scattering particles. The process of optical modeling is based on the traditional phosphor optical modeling procedure established by Dr. Sun’s group. By following the process, we obtain a set of effective parameters, such as the effective scattering model, effective absorption coefficient, and conversion efficiency in both experiment and simulation. In the verification, the chromatic performances and packaging efficiency of the real LEDs are measured and compared with the modeling simulation. Then we use the new optical model to study of packaging efficiency, phosphor reduction and angular correlated-color-temperature deviation with YAG phosphor adding ZrO2 scattering particles. The properties of adding ZrO2 is summarized in the final.
