A luminaire includes a first light source and a second light source, the first and second light source operatively configured to provide amounts of light independently controllable during operation; and an optical system having an input aperture system and an output aperture system. The output aperture system is displaced by a predetermined distance along a forward direction from the input aperture system. The optical system is operatively coupled with the first and second light source and configured to direct light received at the input aperture system to the output aperture system. The output aperture system is configured to output light from the first light source in first directions and light from the second light source in second directions at least in part different from the first directions.

In one or more cross-sectional planes parallel to the first direction, the light-reflective surfaces of the first and second walls have first portions that curve in opposite directions, second portions that are parallel, and third portions that curve in like directions. The first portions are arranged facing the LEEs to provide an input aperture that receives light from the LEEs. The third portions are arranged to provide an exit aperture that outputs output light into an ambient environment. The first and second walls are configured to propagate light from the input aperture to the exit aperture.
