Claim:
1. A luminaire, comprising: a plurality of light sources configured to, in combination, generate a plurality of different colors of light; a first chamber configured to mix the plurality of different colors of light; at least one light exit surface comprising a light transmissive diffuser coupled to the first chamber and configured to further mix light emitted from the plurality of light sources such that said further mixed light is transmitted through said at least one light exit surface; and a second chamber containing at least one first light source of the plurality of light sources and having at least one first wall and a first opening in communication with the first chamber, the at least one first wall configured to prevent the light emitted from the at least one first light source from directly impinging upon the at least one light exit surface, and the first opening configured to permit the light emitted from the at least one first light source to travel through the first opening from the second chamber to the first chamber, wherein at least a portion of the light emitted from the at least one first light source impinges through said first opening directly on a first light reflecting surface, which is distinct from the at least light exit surface, of the first chamber at a point on the first light reflecting surface that is disposed at least half-way along a length of the first light reflecting surface, wherein the first chamber and the at least one light exit surface are configured together to mix the light emitted from the plurality of light sources such that all light exiting the at least one light exit surface is substantially uniform in at least one of brightness or color.
