燈殼漸變肉厚對於光學上之影響

車燈光學的法規要求愈來愈嚴格，燈殼的造型落差也加大，從早期的鐵反射搭配玻璃燈殼演變到現在大多數的燈殼都使用PC為主要材質。 PC燈殼有強度佳，透光性良好及可配合大燈的造型落差大等優點，可以廣泛的應用於車燈上使用，但造型落差大導致燈殼的表面為曲面，當反射鏡投射後經過燈殼的折射不穩定，因而造成光學配光點的NG，此論文中將探討如何將漸變式肉厚變化使用於燈殼上可以讓反射鏡的光學射經燈殼的折射是穩定的進而讓光學的不穩定因素降低。本文利用UG SHIP實例驗証兩個車款在車中配光點不穩定和使用漸變式肉厚於燈殼上後可以讓配光點趨於穩定。

Headlight optical increasingly stringent regulatory requirements, modeling lamp shell gap also increased, from the early iron with glass reflector lamp shells evolved to now most of the lamp housing are using the PC as the main material. PC lamp shell has good strength , good light transmission and can be used with a large gap between headlight shape, etc., can be widely used lights to use, but a large gap between modeling led lamp shell surface is curved, when the mirror projection lamp shell elapsed without refraction stable, resulting in optical light points NG, this paper will discuss how to change the gradient type to use flesh shell allows the lamp reflector optical radiation through refracted light shell is stable thereby allowing optical instability lower. In this paper, UG SHIP instance validation two cars in the car with light point instability and using a gradient-type lamp shell after the flesh in the light distribution point so let stabilize.
