HIGH CRI ADJUSTABLE COLOR TEMPERATURE LIGHTING DEVICES
First Claim
1. A solid state luminaire comprising:
- a control group of solid state emitters; and
a variable group of solid state emitters, the combination of light from said control and variable groups causing emission within a standard deviation of the black body locus (BBL) in a CIE graph, the varying of emission intensity of said variable group of emitters causing the emission of the combined light from said control and variable emitters to vary within a range of color temperatures while emitting within said standard deviation of the BBL.

Abstract
Solid state luminaires and light engines comprising a first group of solid state emitters comprising a first emitter emitting above the black body locus (BBL) in a CIE diagram, and a second emitter emitting below the BBL. The combination of light from the first and second emitters generates an emission color point within a standard deviation of the BBL. A second group of solid state emitters is included, the combination of light from the first and second groups of emitters causes emission within a standard deviation of the black body locus (BBL), wherein varying the intensity of the second group of emitters causes emission from the first and second groups of emitters to vary within a range of color temperatures while still emitting within the standard deviation of the BBL.
