Abstract: A luminaire includes at least first and second waveguides. The first waveguide has a first coupling surface extending between a first surface and a second surface opposite the first surface, and the second waveguide has a second coupling surface extending between a third surface and a fourth surface opposite the third surface. The first and second coupling surfaces define a coupling cavity. The luminaire further includes at least one light source within the coupling cavity.

Abstract: According to one aspect, a waveguide includes a waveguide body having a coupling cavity extending therethrough and a plug member having a first portion disposed in the coupling cavity. The plug member includes an outer surface substantially conforming to the coupling cavity and a second portion extending from the first portion into the coupling cavity and a reflective surface adapted to direct light in the coupling cavity into the waveguide body.
