Patent ID: 8648546

Claim:
A solid state lighting device comprising: at least one first light emitter that emits non-saturated non-white light of a first color point; at least one second light emitter that emits saturated non-white light; and a controller configured to control a ratio of the non-white light of the first color point emitted by the at least one first light emitter and the saturated non-white light emitted by the at least one second light emitter such that a combination of the non-white light of the first color point emitted by the at least one first light emitter and the saturated non-white light emitted by the at least one second light emitter is non-saturated, non-white light of a second color point, the first color point within one of a first area on a 1931 CIE Chromaticity Diagram and a second area on a 1931 CIE Chromaticity Diagram, the first area enclosed by first, second, third, fourth and fifth line segments, the first line segment connecting a first point to a second point, the second line segment connecting the second point to a third point, the third line segment connecting the third point to a fourth point, the fourth line segment connecting the fourth point to a fifth point and the fifth line segment connecting the fifth point to the first point, the first point having x, y coordinates of 0.29, 0.36, the second point having x, y coordinates of 0.32, 0.35, the third point having x, y coordinates of 0.41, 0.43, the fourth point having x, y coordinates of 0.44, 0.49, and the fifth point having x, y coordinates of 0.38, 0.53, the second area enclosed by sixth, seventh, eighth and ninth line segments, the sixth line segment connecting a sixth point to a seventh point, the seventh line segment connecting the seventh point to an eighth point, the eighth line segment connecting the eighth point to a ninth point, and the ninth line segment connecting the ninth point to the sixth point, the sixth point having x, y coordinates of 0.57, 0.35, the seventh point having x, y coordinates of 0.62, 0.32, the eighth point having x, y coordinates of 0.37, 0.16, and the ninth point having x, y coordinates of 0.40, 0.23.
