Claim:
A lighting device comprising: a first group of solid state light emitters; and a first group of lumiphors; wherein: if each of said first group of solid state light emitters is illuminated and each of said first group of lumiphors is excited, a mixture of light emitted from said first group of solid state light emitters and said first group of lumiphors would, in the absence of any additional light, have a first group mixed illumination 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 and fourth 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 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, 0.38, said third point having x, y coordinates of 0.41, 0.455, and said fourth point having x, y coordinates of 0.36, 0.48.
