博士 === 國立中央大學 === 光機電工程研究所 === 102 === This thesis studies the effect color temperature uniformity in different angles by adding scattering particles to different type of white LED light package. Design of white LED package used yellow color phosphor layer to cover blue LED chip; with different package type , phosphor size and phosphor distribution will get different optical results and lighting efficiency. Using optical simulative software to build up and analyze the modal of white LED package, and compare the simulative data with experimental results. Adding scattering particles to phosphor layer and inside of the package to increase the uniformity of color temperature, fitting the data of color temperature to equation and plot the changing trend of color temperature. At last use experimental data to prove the accuracy of simulative data in the last part of this thesis.
