Abstract

A device for increasing the optical power of a solid state light source in the green and/or yellow bands, is disclosed. The device has an integral body having an ingress surface configured to receive light from an emitting portion of the solid state light source, an egress surface substantially opposite the ingress surface, and a recess formed within the body. The recess has an input opening in the ingress surface, an output opening in the egress surface, and a recess surface within the body extending between the input opening and the output opening. The recess surface is configured to reflect visible light with Lambertian scatter characteristics.
