Abstract: A light engine to provide light from a plurality of semiconductor light sources in an automotive lighting system, such as a headlamp, includes at least two substrates each of which has semiconductor light sources mounted thereon. The semiconductor light sources are spaced from one another on the substrates for cooling purposes. The substrates also preferably include at least one layer 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 further includes at least one transfer device comprising a bundle of light pipes, one light pipe for each semiconductor light source, and each light pipe has a receiving end which is located adjacent a respect one semiconductor light source and an emitter end which is located in close proximity to the emitter end of each other light pipe emitter end.
