Abstract
A luminaire comprises a frame and a plurality of optical waveguides retained by the frame. The optical waveguides bound a cavity, and each comprises: a top end and a bottom end opposite the top end; a coupling portion disposed at the top end; an inner side facing the cavity; and an outer side opposite the inner side. The inner and outer sides are disposed between the top and bottom ends. The luminaire further comprises at least one light emitting diode (LED) associated with each optical waveguide. Each of the LEDs are disposed opposite, and configured to direct light into, the coupling portion of the associated optical waveguide. Each optical waveguide is configured to receive the light via the coupling portion and emit the light primarily from the outer side.
