Abstract:
1. A lighting module, comprising: a substrate having an elongated portion; a power unit disposed on the substrate; a light engine disposed on the substrate and coupled to the power unit, the light engine comprising a plurality of light emitting diodes disposed proximate a lit edge of the substrate; a control circuit disposed on the substrate and in communication with the light engine; an interface coupled to the substrate in communication with the control circuit, the interface comprising a connector and a port to receive the connector disposed on opposite sides of the substrate, wherein one of the connector and the port is located on an end of the elongated portion; and a waveguide disposed over the light engine, the waveguide directing light from the light engine to form an illuminated surface area, wherein the waveguide is bounded by a first outer edge member proximate the lit edge and a second outer edge member proximate an unlit edge of the substrate that is spaced apart from and parallel to the lit edge of the substrate, wherein the first outer edge member has an inner surface, an outer surface, and a first profile extending along the length of the lit edge that curves relative to the direction of light from the plurality of light emitting diodes and directs the light toward the unlit edge wherein the second outer edge member has a second profile extending along the length of the unlit edge that curves to match the first profile of the first outer edge member on the lit edge, and wherein the inner surface of the first outer edge member has a coating layer adapted to reflect light disposed thereon.
