Abstract

A lighting device comprising sources of visible light comprising solid state light emitters and/or luminescent materials emitting three or four different hues. A first group of the sources, when illuminated, emit light of two hues which, if combined, would produce illumination having coordinates within an area on a 1931 CIE Chromaticity Diagram defined by points having coordinates: 0.59, 0.24; 0.40, 0.50; 0.24, 0.53; 0.17, 0.25; and 0.30, 0.12. A second group of the sources is of an additional hue. Mixing light from the first and second groups produces illumination within ten MacAdam ellipses of the blackbody locus. Also, a lighting device comprising a white light source having a CRI of 75 or less and at least one solid state light emitters and/or luminescent material. Also, methods of lighting.
