A luminaire includes a frame, an ambient light source positioned within the frame adjacent a first end of the frame, a downlight light source positioned within the frame adjacent a second end of the frame, a diffuser connected to the frame and at least partially surrounding the ambient light source, and a reflector configured to direct light emitted by the downlight light source. A first driver is in electrical communication with the ambient light source and is configured to adjust the illuminance of the ambient light source. A second driver is in electrical communication with the downlight light source and is configured to adjust the illuminance of the downlight light source. A controller is in electrical communication with and send control signals to the drivers to change the light sources between a plurality of illuminance modes, which includes a circadian effective mode and a circadian ineffective mode.

Circadian effective luminaire

Multipurpose lighting systems and methods of providing controllable lighting are provided. A lighting system includes a sheet of flexible material, a plurality of light sources and a controller. The plurality of light sources are attached to the sheet of flexible material and configured to emit diffused light. The controller is coupled to the plurality of light sources and is configured to control one or more of the plurality of light sources according to one of a plurality of prescribed lighting characteristics associated with a respective plurality of different lighting tasks. In some examples, the lighting system includes a camera coupled to the sheet of flexible material configured to capture at least one image of an object synchronously with the light emitted by the plurality of light sources.
