Claim Text:
1. A luminaire module comprising: a first set of light-emitting elements (LEEs) disposed on one or more substrates and adapted to emit light in a forward direction; a first light guide shaped to guide light, emitted by the first set of LEEs and received at an input end of the first light guide, in the forward direction to an output end of the first light guide and provide first guided light at the output end of the first light guide; a first optical extractor optically coupled with the output end of the first light guide and adapted to receive the first guided light, the first optical extractor having at least one redirecting surface, the at least one redirecting surface of the first optical extractor being adapted to reflect at least a portion of the light received at the first optical extractor in a first direction that has a component orthogonal to the forward direction; a second set of LEEs disposed on the one or more substrates and adapted to emit light in the forward direction, the second set of LEEs being independently controllable from the first set of LEEs; a second light guide optically shaped to guide light, emitted by the second set of LEEs and received at an input end of the second light guide, in the forward direction to an output end of the second light guide and provide second guided light at the output end of the second light guide; and a second optical extractor optically coupled with the output end of the second light guide and adapted to receive the second guided light, the second optical extractor having at least one redirecting surface, the at least one redirecting surface of the second optical extractor being adapted to reflect at least a portion of the light received at the second optical extractor in a second direction that has a component orthogonal to the forward direction and antiparallel to the orthogonal component of the first direction, wherein the first and second light guide are spaced apart forming a space between the first and the second light guide, wherein the space is filled with a medium to control total internal reflection at respective interfaces of the first and second light guides with the medium, and wherein the medium is an electronically controllable fluid.
