Patent ID: 8508116

Claim:
A lighting device comprising: at least a first multi-chip light emitter and a second multi-chip light emitter, the first multi-chip light emitter comprising at least a first solid state light emitter and a second solid state light emitter, the second multi-chip light emitter comprising at least a third solid state light emitter and a fourth solid state light emitter, the first solid state light emitter emitting light of a first hue, the second solid state light emitter emitting light of a second hue, the third solid state light emitter emitting light of a third hue, the fourth solid state light emitter emitting light of a fourth hue, the first hue differing from the third hue by fewer MacAdam ellipses than the number of MacAdam ellipses by which: the first hue differs from the second hue, the first hue differs from the fourth hue, the second hue differs from the third hue, the second hue differs from the fourth hue, or the third hue differs from the fourth hue, the first solid state light emitter spatially offset relative to the third solid state light emitter by at least 10 degrees.
