摘要：
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.
