This study presents the influence of the distance between phosphor layers in the dual-layer and triplelayer remote package on luminous efficacy. During the simulation, it is recognized that an appropriate distance can produce higher luminous flux of the multi-chip white LED (WLEDs) through adjusting the distance between two and three phosphor layers. According to the research results, 0.1 mm is the outstanding distance between two phosphor layers so that the performance of MCW-LEDs can be accomplished the best optimal effect. In addition, the simulation results show that the dual-layer structure yielded higher optical properties than the triple – layer structure in relation to the distance.
