Abstract
Luminaires are described herein employing waveguides and associated architectures for dynamic alteration of illuminance distribution patterns. The waveguide includes a light extraction component. The waveguide transmits light from a light source to the light extraction component by total internal reflection (TIR). The light extraction component includes one or more reversibly moveable surfaces for altering illuminance distribution patterns of the luminaire in response to one or more forces applied to the light extraction component by a force application assembly of the luminaire.
