1. A luminaire comprising:
- at least one light source;
a waveguide including a waveguide body and a light extraction component, the waveguide body transmitting light from the at least one light source to the light extraction component, the light extraction component emitting an emitted light from the waveguide in a light distribution; and
at least one optic disposed external to the waveguide, the at least one optic radially surrounding the waveguide and arranged to receive at least a portion of the emitted light from the waveguide, the at least one optic comprising a curved reflective surface and the light extraction component selectively irradiating the curved reflective surface to alter the light distribution emitted by the light extraction component.

Abstract
Luminaires are described herein employing waveguides and associated architectures for dynamic alteration of illuminance distribution patterns. In one aspect, a luminaire described herein comprises a waveguide body and light sources having differing angular positions relative to the waveguide body for altering illuminance distribution patterns of the luminaire according to one or more activation patterns of the light sources. The differing angular positions can be located at the perimeter of the waveguide body and/or at one or more internal locations of the waveguide body.
