碩士 === 國立屏東科技大學 === 車輛工程系所 === 97 === In this thesis, a projection LED automotive headlamp system has been developed by using optical simulation software. Two critical design concepts are proposed, one is the application of diffraction optical elements on the encapsulation surface of LED, and the other is the focusing performance and improves the illumination. The latter, a redesign of asymmetric LED base, can ignore the need of optical shield, and simplify the design and reduce energy loss. In this simulation, the optimization of the design for single LED is first investigated. The arrangement of optical devices in the individual module of single LED is
then established. Furthermore, single reflector, lens and LED base are employed to overcome the complexity of assembly for the integrated module array. Finally, a real model of single LED module is fabricated to verify the simulation results. The projection LED automotive headlamp
system designed in this study provides a simplified structure, higher efficiency and less LED requirement.
