Abstract
According to one aspect, a waveguide comprises a waveguide body having a coupling cavity defined by a coupling feature disposed within the waveguide body. A plug member comprises a first portion disposed in the coupling cavity and an outer surface substantially conforming to the coupling feature and a second portion extending from the first portion into the coupling cavity. The second portion includes a reflective surface adapted to direct light in the coupling cavity into the waveguide body.
Claims20
A luminaire, comprising:
- a plurality of waveguide portions each of the plurality of waveguide portions comprising a waveguide body, wherein the waveguide body has a width and length that are substantially greater than a thickness thereof, the thickness extending in a direction between a first side and a second side, and a coupling cavity disposed within the waveguide body extending in the direction, wherein the coupling cavity comprises a coupling feature;
- a plug member having a first portion disposed in the coupling cavity and an outer surface substantially conforming to the coupling feature and a second portion extending from the first portion into the coupling cavity wherein the second portion includes a reflective surface adapted to direct light in the coupling cavity into the waveguide body;
- and
- at least one LED disposed to direct light into the coupling cavity.

A waveguide, comprising:
- a waveguide body having a width and length that are substantially greater than a thickness thereof where the thickness extends in a direction between a first side and a second side, wherein the waveguide body comprises a first plate and a second plate and wherein the first plate includes a first outer face that defines the first side and a first inner face and the second plate includes a second outer face that defines the second side and a second inner face, the first inner face being in contact with the second inner face;
- a coupling cavity comprising a coupling feature, wherein the coupling cavity is disposed within the waveguide body and extends in the direction;
- a plug member having a first portion disposed in the coupling cavity and an outer surface substantially conforming to the coupling feature and a second portion extending from the first portion into the coupling cavity wherein the second portion includes a reflective surface adapted to direct light in the coupling cavity into the waveguide body;
- and
- at least one LED disposed to direct light into the coupling cavity.
