SEMICONDUCTOR LIGHT ENGINE FOR AUTOMOTIVE LIGHTING

摘要

A light engine for an automotive lighting system includes at least one substrate and a plurality of semiconductor light sources mounted to each of the at least one substrate. Each adjacent semiconductor light source is spaced from each other adjacent semiconductor light source on the substrate to enhance cooling of the semiconductor light sources during operation thereof. The light engine further includes at least one transfer device operable to receive light emitted by the semiconductor light sources on the at least one substrate and to transfer the received light to at least one location spaced from the substrate, wherein the transfer device comprises at least one light pipe, each light pipe has a receiving end to receive light emitted from a semiconductor light source and an emitting end to emit the received light.
