Abstract
A lighting device comprising at least one non-white light source, at least a first supplemental light emitter and at least a second supplemental light emitter. The non-white light source(s) is outside an area from 0.01 u′v′ above to below the blackbody locus, and within an area defined by curves between saturated light of wavelength 430-480 nm and 560-580 nm and line segments between saturated light of wavelength 430-580 nm and 480-560 nm. The first supplemental light emitter(s) have dominant emission wavelength of 465-540 nm. The second supplemental light emitter(s) have dominant emission wavelength of 600-640 nm.
