Claims5
A luminaire having one end adapted to mount on a vertical mast spaced from an area to be illuminated, said luminaire comprising an enlarged main housing having a surround wall generally downwardly-facing to form an open mouth defining the rim of said main housing, an inverted bowl-shaped reflector having a rim portion extending out of said mouth at an end remote from said one end, a bowl-shaped refractor housing hinged to said housing at said end remote from said one end, said refractor housing including a refractor affixed to said refractor housing configured to close the open mouth of said housing, means for releasing said refractor housing to cause said refractor housing to depend from said remote end to partially uncover said mouth for access to the interior of said main housing, a reflector mounting bracket recessed in said main housing adjacent the remote end thereof, said bracket comprising a depending wall and an end wall stepped from said depending wall with said walls inset in said main housing, a forked member affixed to said reflector intermediately along the bowl shape thereof for mating with said bracket to position said reflector in said main housing, said bracket end wall defining a landing surface for retaining thereon said forked member as the reflector is advanced into said main housing, and notches in said depending wall for receiving said forked member in a tight-fitting relationship to locate and to hold said reflector relative to the remote end of said main housing and relative to sides of the wall thereof.
A method for inserting a reflector into the upper housing of a luminaire to which a lower housing supporting a refractor is attached by hinges, comprising the steps of opening the luminaire while standing to one side by releasing fasteners on each side of the lower housing permitting it to depend from the upper housing, sliding a fork mounted on the front of the reflector onto a stationary bracket internally in the housing, partially advancing the fork onto the bracket, setting the opposite sides of the reflector within bayonet fasteners on opposite sides of the housing, advancing the fork fully onto the bracket to position the front of the reflector within the upper housing, and tightening the bayonet fasteners to properly position the sides of the reflector.
