A light engine 20 to provide light from a plurality of semiconductor light sources 40 in an automotive lighting system, such as a headlamp, includes a substrate 24 upon which the semiconductor light sources are mounted. The semiconductor light sources are spaced from one another on the substrate for cooling purposes. The substrate also preferably includes at least one layer 48 of heat transfer material which assists in transferring waste heat from the semiconductor light sources to a heat sink or other cooling means. The light engine 20 further includes a transfer device 28 comprising a bundle of fiber optic cables 60, one cable for each semiconductor light source 40, and each cable has a receiving end 32 which is located adjacent a respect one semiconductor light source 40 and an emitter end 36 which is located in close proximity to the emitter end of each other cable emitter end. The substrate 24 can be located in a location which is convenient for the purposes of cooling the semiconductor light sources while the emitter end of the cables of the transfer device can be located adjacent a lens of the headlamp or other automotive lighting system. |
