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.
