We developed a hybrid optical headlamp in which LEDs and blue laser diode were properly controlled to maximize a level of 1.5 lx on road. In optical design, we simplified laser phosphorescence model for realizing white light by using Gaussian cross-sectional beam. We simulated various optical systems to capture the focal position and selected the optimized position on simulation. Ray tracing simulation results fulfill the ECE-R112 regulation.
