Abstract
A lighting device in which a solid state light emitter in a first multi-chip light emitter is spatially offset relative to a solid state light emitter in a second multi-chip light emitter. A lighting device comprising first, second and third multi-chip light emitters, in which any solid state light emitter in the second multi-chip light emitter that is spatially offset relative to a first solid state light emitter on the first multi-chip light emitter by less than 10 degrees emits light of a hue that differs from the hue of light emitted by the first solid state light emitter by more than seven MacAdam ellipses. A solid state light emitter support member comprising a center region and at least first, second and third protrusions extending from the center region. A lighting device comprising at least a first housing member, and means for emitting substantially uniform light.
