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.
