Abstract
Luminaire housings for architectural, industrial and warehouse applications have extrusions with parallel flat sides connected by a cross member. The wireway can be enclosed by the extrusion's roof or by cover segments clamped over an open top extrusion. Wireway openings provide access to the wireway. Nuts slid into T-channels in the roof or cover segments provide for mounting or suspension via wall brackets, cables, and housing brackets. Threaded nipples accessible through the roof or cover segments provide for pendant stem mounting. Continuous run brackets can join housings end to end. Optical elements slid into slots and channels in the housing can be retained by end caps. A housing cover over the wireway can be clamped in place by screws threaded into fixture brackets retained within the housing. The housing grooves in the cover segments can slidably engage the extrusion until the cover segments are clamped in place.
