摘要

目前而言，車燈仍然以白熾燈、鹵素燈及HID為主要發光源，但是在國際車展上，我們可以發現到各國汽車廠商已將LED車燈列入概念車配備中展示，藉以吸引消費者眼光。因此本研究將以LED為發光源，設計出符合歐規ECE R19的前霧燈。其反射罩設計為上、下不同曲率的曲面以及連接上、下不同曲率之曲面的兩側平面與燈具開口呈現相互對稱之向外傾斜8度，其功用在於控制光型的分布長度，然而，上、下不同曲率之曲面，其功能為上曲面是將往上發散之光束將其反射至下方，下曲面是將往下發散之光束經由反射後形成平行光束，將原本集中照射於中心點之光源整形為集中照射於水平線下方之光型，另外，還是有些發散光線無法藉由反射罩完全收集運用，因此再透過一個具有上、下不同曲率之透鏡，將原本無法收集之發散光線有效收集運用，增加光源利用率。

Currently vehicles still adopt incandescent lamps, halogen lamps, and HID as their major lighting sources. But at international auto exhibitions, we may find auto makers have already mounted LED lamps on their concept cars for demonstration in order to draw consumers’ eye. As a result, this study designed an Economic Commission for Europe Regulation 19-conforming front fog lamp using LED as a light source. The reflector had a curve surface with different upper and lower curvatures. The two sides of the curve surface with different upper and lower curvatures demonstrated an outward-leaning angle of 8 degrees with the lamp opening. The purpose was to control the distribution length of the light. The curve surface was designed with different upper and lower curvatures in that the upper curve surface was to reflect the upward-emitting beam downward, and that the lower curve surface was to translate, through reflection, the downward-emitting beam into a parallel one, by adapting the light which originally concentrated on the center to a light which concentrated below the horizontal line. However, some emitted light still could not be completely gathered through the reflection cover. For this reason, through a lens with different upper and lower curvatures, the emitted light which originally could not be collected was effectively collected for use to increase the utility of the light source.
