HID Driven Focus-less Optics System for Complete Automotive Distributed Lighting Systems 980877

Presented in this paper is a description of an automobile that is partially retrofitted with a hybrid HID/fiber focus-less optic system. Tail lights are constructed that provide stops, turns, CHMSL, and backups. Lenses are used to meet the most demanding beam patterns. Focus-less optics (FLO) are used with waveguides to collect the rest of the light off the HID and to distribute to the rest of the car. Preliminary measurements indicate that the tail light beam patterns are legal according to SAE and DOT specifications. Different features discussed include electro mechanical modulators (EMM), liquid crystal device modulators (LCD).
