Abstract

A luminaire for architectural, industrial and warehouse applications can be assembled using an extruded housing having curved sides connected by a cross member. Windows in the curved sides can allow light to exit toward the sides of the luminaire while most of the light exits through a lens on the bottom. The extrusion can have channels and slots such that optical elements and an LED array can be slid into the housing and retained by end caps. A housing cover can overlie a wireway while being held in place by screws creating a clamping force between the housing cover and fixture brackets retained within the housing. The luminaire can be suspended by the fixture brackets or by elements attached to the fixture brackets.

Dependent claims

A luminaire comprising:

an extruded housing formed from an extrusion comprising a profile, wherein the profile comprises a height and a width, wherein the extrusion comprises a length, a first end and a second end distanced from the first end by the length, wherein the extrusion comprises a plurality of length running elements, wherein the length running elements comprise a cross member, two curved sides, two lens channels, two LED array channels directly under the cross member, four side lens channels, and two fixture bracket supports, and wherein each curved side comprises at least two window openings;
a first endcap attached to the first end and a second endcap attached to the second end;
a housing cover covering a top opening wherein the top opening is above the fixture bracket supports and runs from the first end to the second end, and wherein the housing cover comprises a wireway opening;
a wireway cover covering the wireway opening and wherein the wireway cover is configured to be removed and reinstalled over the wireway opening;
an LED array comprising a circuit board and a plurality of LEDs wherein the LED array is sized to simultaneously slide into both the LED array channels;
a lens wherein the lens is sized to simultaneously slide into both lens channels;
and
two side lenses wherein each of the side lenses is sized to simultaneously slide into two of the side lens channels.
