Abstract
A luminaire housing includes a frame having a securing member, a door panel movable between open and closed positions relative to the frame, and a hinge member. The hinge member pivotally connects the door panel and the securing member and includes a fixed end portion, a first angled ramp portion, a second angled ramp portion, and a centering portion. The fixed end portion is attached to the door panel and the first angled ramp portion extends from it. The fixed end portion includes an open hinge surface. The second angled ramp portion extends from the first angled portion and the centering end portion extends from the second angled ramp portion, forming a closed hinge surface between them. The open hinge surface of the first hinge member is in contact with the securing member of the frame when the door panel is in the open position. The closed hinge surface is in contact with the securing member when the door panel is in the closed position allowing the first hinge member to be in continuous contact with the securing member when the door panel is moved between the open and closed positions.
