星空顶衬的设计和出光效果研究

Study on Starry Sky Headliner Design and Lighting Effect

摘要: 传统顶衬上的发光零件主要有前排车顶控制台和后排阅读灯等，为了提升高端车型客户的车内感知体验，可以在顶衬上增加星空效果。用大量点光源的出光效果来模拟真实星空的繁星闪烁，将带有LED光源的控制模块布置在顶衬背面，从光源处引出的光纤起导光作用。多根光纤组成的多个亮点可以设计组合成各种不同的图案。LED光源颜色不同，可以得到不同颜色的星光，营造良好的智能座舱环境，带来极致的驾乘坐享体验。

Abstract: The lighting parts on the traditional headliner mainly include the front roof console and rear reading lamps, etc. in order to improve the in car perception experience of high model customers, we could add starry sky effect on the headliner. The lighting effect of a large number of point light sources simulates the stars in the real sky. The control module with LED light source is arranged at the headliner backside, and the optical fiber led out from the light source plays the role of light guide. Multiple bright spots composed of multiple optical fibers can be designed as different patterns. Different colors of LED light source can get different colors of starry sky light to create good intelligent environment and bring ultimate driving experience.
