Luminaire with controllable light emission

A luminaire comprising:

• a plurality of first waveguide sections, each of the plurality of first waveguide sections 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 plurality of second waveguide sections, each of the plurality of second waveguide sections 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 s and the second secondary light emitting surface s being disposed adjacent one another;
• at least one first LED being optically coupled to each of the first waveguide sections and at least one second LED being optically coupled to each of the second waveguide sections each of the at least one first LED and the at least one second LED being independently operable.

A free standing luminaire comprising:

• a support structure being supportable on a surface, the support structure supporting a waveguide;
• a plurality of LEDs optically coupled to the waveguide such that activation of the plurality of LEDs causes light to be emitted from the waveguide, where the light emission pattern and light properties of the emitted light are controllable.
