Abstract—Recent progress in development of blue laser diodes and their integration with phosphors have enabled a new category of solid state light sources that deliver high luminance and advanced illumination effects especially for automotive lighting. In this presentation, we discuss the challenges of phosphor converted automotive laser light sources including optical performance, color uniformity, heat management and safety measures with different laser light source system design. An update on the capabilities of automotive laser light source is provided including progress in luminous flux, luminance, efficacy, and color quality. Recently developed, innovative fiber coupled laser light modules with reflective phosphor produce precisely shaped road illumination pattern with compact optics and heatsink, which enables novel automotive lighting applications and stylish design covering low beam, high beam and patterned light projection by utilizing minimized size, ultra-long range and short throw optical modules. Additionally, a dynamic laser light module for ADB with time variable illumination consisting of fiber coupled blue laser diode, a biaxial MEMS scanner and remoted phosphor will be introduced. The potential for simultaneous range detection (LiDAR) capabilities of the dynamic laser module and the feasibility of visible light communication (LiFi) with modulated laser light source will be presented, specifically for future intelligent automotive lighting applications.
