LED汽車頭燈光學設計回顧

The Review of LED-based Vehicle Headlamp Optical Design

摘要


本文探討LED汽車頭燈近年來光學設計技術發展概況,包含專利及文獻探討與軟體模擬設計,車頭燈光學設計包括投射式、多面鏡反射式、拋物面反射式、RXI及光纖導光式車頭燈設計;軟體模擬則採用自由曲面與雙反射罩疊加方式LED車頭燈照明系統,使用兩顆5瓦/311流明之OSRAM LED,其光學效率可達74%。

In this thesis, LED-based vehicle headlamp optical designs have been reviewed, including the development of projection type, multi-surface reflection type, parabolic reflection type, RXI and fiber-based light distribution type. The review covers journal paper and patent literatures. In addition, a software simulation for free-form surface LED-based vehicle headlamp optical design has also been presented. The design used of two 5W/311 lm OSRAM LED, the simulated optical efficiency can reached 74%.
