Abstract
Solid state light emitting devices and/or solid state lighting devices use three or more phosphors excited by energy from a solid state source. The phosphors are selected and included in proportions such that the visible light output of such a device exhibits a radiation spectrum that approximates a black body radiation spectrum for the rated color temperature for the device, over at least a predetermined portion of the visible light spectrum.
