The new LED glass optics "ShopWhite" consists of a base reflector with exchangeable diffuser lenses: a concept well known and tested with CDM systems. Likewise, our new color-mixing system provides multiple beam angles, depending on the diffuser lens used. The multi-shape facets of the reflector pre-mix the light while the lens with double-sided, sophisticated facet design makes the color-mixing complete. "ShopWhite" has a very high efficiency >90% that can even be increased with an optional AR coating. The color uniformity for a red-white LED module is better than four MacAdam ellipses for an 18° spot.
