Patent ID: 8513875

Claim:
A lighting device comprising: a first group of solid state light emitters, said first group of solid state light emitters including at least one solid state light emitter; at least a first luminescent material; a second group of solid state light emitters, said second group of solid state light emitters including at least one solid state light emitter; and at least a first power line, said first group of solid state light emitters and said second group of solid state light emitters electrically connected to said first power line, wherein: said first group of solid state light emitters, when illuminated, emits light having a peak wavelength in the range of from 430 nm to 480 nm; said first luminescent material, when excited, emits light having a dominant wavelength in the range of from about 555 nm to about 585 nm; said second group of solid state light emitters, when illuminated, emits light having a dominant wavelength in the range of from 600 nm to 630 nm; when current is supplied to said first power line, a combination of (1) light exiting said lighting device which was emitted by said first group of solid state light emitters, and (2) light exiting said lighting device which was emitted by said first luminescent material would, in an absence of any additional light, produce a sub-mixture of light having x, y color coordinates which define a point which is within an area on a 1931 CIE Chromaticity Diagram enclosed by first, second, third, fourth and fifth line segments, said first line segment connecting a first point to a second point, said second line segment connecting said second point to a third point, said third line segment connecting said third point to a fourth point, said fourth line segment connecting said fourth point to a fifth point, and said fifth line segment connecting said fifth point to said first point, said first point having x, y coordinates of 0.32, 0.40, said second point having x, y coordinates of 0.36, 0.48, said third point having x, y coordinates of 0.43, 0.45, said fourth point having x, y coordinates of 0.42, 0.42, and said fifth point having x, y coordinates of 0.36, 0.38.
