Luminaire with controllable light emission
First Claim
1. A luminaire comprising:
- a first waveguide having a first primary light emitting surface directed in a first direction and a first secondary light emitting surface directed in a second direction, and a second waveguide having a second primary light emitting surface directed in the second direction and a second secondary light emitting surface directed in the first direction, the first secondary light emitting surface and the second secondary light emitting surface being disposed adjacent one another such that the first primary light emitting surface and the second primary light emitting surface face generally away from one another, and the first primary light emitting surface comprising a first plurality of light extraction features that emit light in a first light emission pattern and the second primary light emitting surface comprising a second plurality of light extraction features that emit light in a second light emission pattern, the first light emission pattern being different than the second light emission pattern;
a first plurality of LEDs being optically coupled to the first waveguide such that activation of the first plurality of LEDs causes light to be emitted from the first primary light emitting surface and a second plurality of LEDs being optically coupled to the second waveguide such that activation of the second plurality of LEDs causes light to be emitted from the second primary light emitting surface, and a controller controlling operation of the first plurality of LEDs and the second plurality of LEDs such that the first plurality of LEDs and the second plurality of LEDs are independently operable.

Abstract
A luminaire includes a first waveguide having a first primary light emitting surface directed in a first direction and a first secondary light emitting surface directed in a second direction. A second waveguide having a second primary light emitting surface directed in the second direction and a second secondary light emitting surface directed in the first direction. A first plurality of LEDs are optically coupled to the first waveguide and a second plurality of LEDs are optically coupled to the second waveguide. The first and second waveguides are independently operable. The first and second plurality of LEDs may comprise LED groups where each of the LED groups are independently controllable. The light emission pattern and light properties of the emitted light are controllable.
