Abstract
A full spectrum white light emitting device comprising: a broadband solid-state excitation source operable to generate broadband blue excitation light; and at least one photoluminescence material which generates green to red light, wherein the device generates white light whose intensity over the blue to cyan region of the spectrum has a maximum percentage deviation from the intensity of light of a black-body or CIE Standard Illuminant D of less than 50%.
