本論文旨在探討雷射車燈之光學模組設計，包含一款近光燈及一款兼具可見光與紅外線功能之遠光燈。本論文採用450nm高功率藍光雷射二極體作為激發光源，使用混光導光柱將雷射光束導引至反射式玻璃陶瓷螢光粉片，激發出白光。本論文提出的雷射車燈系統設計可滿足ECE R113對稱頭燈光型與ECE R112非對稱頭燈光型之車燈照度規範，模組光學效率可達60%以上，體積可限縮在長95mm寬45mm以內，相當於減少現今一般車用頭燈30%體積。

The purpose of this thesis is focusing on the design of the optical module of laser headlamp system, including a low beam and a high beam with visible light and infrared ray function. In this research, 450nm high power blue laser diodes were applied as excitation light source, which was guided to the reflective ceramic phosphor plate with the design of the mixing light pipe, finally converted to white light. These headlamp designs meet the ECE R113 and ECE R112 standard separately, as well as the efficiency of headlamp module both reached up to 60%. Besides, the volume size of these modules can be limited to 95mm in length and 45mm in width so that indicates that we can reduce the size up to 30% of the existing automotive headlamp.
Keywords: Laser headlight、Laser diode、Glass-ceramics phosphor、porjection lens、Mixing light pipe
