Abstract
A luminaire includes a waveguide having first and second opposing ends and first and second opposing sides between the first and second ends. The waveguide is configured to totally internally reflect light propagating through the waveguide in a first direction and direct light propagating through the waveguide in a second direction through at least one of the first and second sides. A reflective body is coupled to the second end of the waveguide and configured to reflect light propagating towards the second end of the waveguide such that the light propagates towards the first end of the waveguide.
