Lighting system using multiple colored light emitting sources and diffuser element

摘要

A light emitting apparatus has a radiation source for emitting multi-colored radiation. A diffuser material receives at least a portion of the multi-colored radiation emitted by the radiation source and converts the multi-colored radiation into forward transferred radiation and back transferred radiation. An optic device is coupled to the diffuser material and is adapted to receive the back transferred radiation and extract at least a portion of the back transferred radiation from the optic device.
