Paper Abstract

Recently, there is an interest in the laser-based white light source for illumination and display applications. The laser-based white lights inherently have much higher luminance than the corresponding LEDs. Moreover, laser diodes are often more efficient when operating at higher current densities and are with smaller form factors, which may outperform LEDs in the future. Based on this, in this paper, we combine the design of the light guide and reflective type remote phosphor structures in order to improve the overall performance of the laser-based white light source. In addition, these well-designed white light sources will provide the more flexible architecture for designing the subsequent lighting system. With the introduction of the innovative design for the laser-based illumination system, multiple applications incorporating laser and remote phosphor elements for improving lighting efficiency and quality were obtained.
