Abstract: A luminaire includes a housing, light-emitting diodes and a light guide. A lateral direction from a top side to a bottom side of the housing is a preferred direction. A front side of the housing forms an aperture. The light guide substantially spans the aperture. In operation, the LEDs emit light toward the preferred direction, which light enters a light coupling surface of the light guide, where it propagates and is substantially retained by total internal reflection. The light guide includes light extraction features to redirect a portion of the light out of total internal reflection, so that some of the light exits the housing through the aperture. The light extraction features redirect some of the light so that more of the light exits the aperture between a normal direction of the light guide and the preferred direction, than between the normal direction and the non-preferred direction.

Abstract: A lighting system includes first and second component housed within respective first and second housings, and a connector. The first housing defines a first substantially rectangular cross-section that extends from a first end to a second end. The first component is capable of emitting light. The second housing defines a second substantially rectangular cross-section. The second substantially rectangular cross-section extends from a third end to a fourth end. The connector connects the second end with the third end. The connector defines a third substantially rectangular cross-section that is substantially identical to the first and second substantially rectangular cross-sections. The third substantially rectangular cross-section extends along a path from the second end to the third end. The path includes at least one curve of at least fifteen degrees between the second end and the third end, and/or, the substantially rectangular cross-section rotates at least fifteen degrees about the path.
