Abstract
A lighting assembly includes a light engine and a light guide. The light engine edge lights the light guide and includes a control assembly that controls light output according to one or more parameters to produce light output from the lighting assembly with a desired characteristic. Lighting assemblies are combined to form a modular lighting assembly.
Claims36
A lighting assembly, comprising:
- a light engine comprising a first coupling member and a second coupling member mechanically coupled to the first coupling member;
- a first light guide secured to the first coupling member;
- a second light guide secured to the second coupling member;
- a first light source retained by the first coupling member and located to edge light a light input edge of the first light guide;
- and
- a second light source retained by the second coupling member and located to edge light a light input edge of the second light guide;
- and
- wherein the first coupling member and the second coupling member are rotatable relative to each other to adjust an angular position between the first light guide and the second light guide, and a light ray angle distribution of light output by the lighting assembly varies as a function of the angular position between the first light guide and the second light guide.

A track-based lighting assembly, comprising:
- a track;
- and
- a lighting fixture, the lighting fixture comprising:
- a light engine comprising a first coupling member and a second coupling member mechanically coupled to the first coupling member, and further comprising a connector that electrically and mechanically couples the light engine to the track;
- a first light guide secured to the first coupling member;
- a second light guide secured to the second coupling member;
- a first light source retained by the first coupling member and located to edge light a light input edge of the first light guide;
- and
- a second light source retained by the second coupling member and located to edge light a light input edge of the second light guide;
- and
- wherein the first coupling member and the second coupling member are rotatable relative to each other to adjust an angular position between the first light guide and the second light guide, and a light ray angle distribution of light output by the lighting fixture varies as a function of the angular position between the first light guide and the second light guide.
