Abstract
Illumination systems are described for illuminating a target area, e.g., a floor of a room, using active illumination devices in optical communication with passive illumination devices. The active and passive illumination devices of the illumination system are configured and arranged relative to each other in a variety of ways so a variety of intensity distributions can be provided by the illumination system. Such illumination system is implemented to provide light for particular lighting applications, including office lighting, garage lighting, or cabinet lighting.
