Light generating module has semiconducting light sources, transparent element(s) with diffractive structures for different colors directed at least approximately parallel to optical axis

摘要

The module has a reflector (10), at least 3 semiconducting light sources (12-14) and at least one transparent element (20) in the beam path with at least one diffractive structure (22-24) to deflect the light. At least one source generates at least approximately red, at least one green and at least one blue light. The element has diffractive structures for the different colors that are directed at least approximately parallel to the optical axis.
