Abstract:
1. A lighting device comprising: at least one first solid state light emitter comprising a dominant wavelength in a range of from 500 nm to 570 nm; at least one second solid state light emitter comprising a peak wavelength in a range of from 430 nm to 480 nm; and at least one first lumiphor arranged to receive emissions from the at least one first solid state light emitter and responsively generate lumiphor emissions comprising a peak wavelength of at least about 591 nm; wherein the lighting device is arranged to output combined emissions including at least a portion of light emissions generated by each of the at least one first solid state light emitter, the at least one second solid state light emitter, and the at least one first lumiphor; and wherein the lighting device is devoid of any lumiphor (a) comprising a peak wavelength in a range of from 555 nm to 590 nm, and (b) being arranged to receive emissions from the second solid state light emitter.
