摘要：

In this paper, the impact of SiO2 (silica) concentration on angular CCT uniformity of a multi-chip white LED (MCW-LED) is presented. Here, the silica particles are mixed with the phosphor particles to enhance the scattering. It is suggested that the silica-phosphor layer with 10 % weight of SiO2 can improve the uniformity of CCT due to enough scattering property in the layer. The simulation results show that the CCT deviation can reduce from 2,211 to 1,719 K for the MCW-LED working averagely at CCT 7,700 K.
