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.
Claims13
An illumination system, comprising:
- an active illumination device configured to output
- backward light in obtuse angles relative to a forward direction, the forward direction extending from the active illumination device to a target surface, and
- forward light in acute angles relative to the forward direction;
- and
- a passive illumination device arranged to receive backward light output by the active illumination device and redirect the received light toward the target surface,
- wherein an entirety of the active illumination device and an entirety of the passive illumination device are spaced apart from each other in both the forward direction and in a first direction perpendicular to the forward direction.
