Paper Abstract

The concept of the remote phosphor is proven to be one of the effective solutions for improving luminous efficacy of pc-WLEDs by solving the problem of phosphor thermal and scattering loss. However, most of them need to use larger packaging design to enhance their performance. Such development is adverse to market trends, which also resulted in higher manufacturing costs and the difficulties in luminaire design. In this paper, we present the analysis of pc-WLEDs as the function of the packaging size and figure out its limitation, so that we can apply to reduce the device size but keep the luminous efficacy as high as possible.
