Patent ID: 8508117

Claim:
A lighting device comprising: at least one electrically activated first solid state emitter having a first dominant wavelength in a range of from 430 nm to 470 nm; at least one electrically activated second solid state emitter having a second dominant wavelength in a range of from 471 nm to 493 nm; at least one electrically activated third solid state emitter having a third dominant wavelength in a range of from 600 nm to 650 nm; and at least one lumiphor overlying, located remotely from, and arranged to receive emissions from any of the at least one first solid state emitter and the at least one second solid state emitter, and to responsively emit light having a fourth dominant wavelength that differs from the first, second, and third dominant wavelength; wherein spectral output of the lighting device includes in combination at least a portion of emissions from each of the at least one first solid state emitter, the at least one second solid state emitter, the at least one third solid state emitter, and the at least one lumiphor.
