Abstract

An illumination system includes a radiation source capable of emitting primary radiation and a luminescent material. The luminescent material includes a blend of a first phosphor capable of converting the primary radiation into a broad-band emission in the yellow range of the electromagnetic spectrum, and a second phosphor capable of converting the primary radiation into a multiple narrow-band emission in the red and green range of the electromagnetic spectrum.
