Abstract:
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.
