Abstract: A clamp for securing a pole top luminaire to the top of a support post. A fitter clamp is disposed inside of the support post, while the housing of the luminaire includes a base portion which extends from the luminaire downward surrounding the outer circumference of the support post. Threaded fasteners extend through the housing base portion to engage the fitter clamp, causing the clamp to expand and compressively engage the support post between the fitter clamp and the luminaire housing base portion.

Abstract: A laminated ballast core is provided comprising a plurality of nearly identically shaped lamination pieces. Each lamination piece is of a general L-shape and has a notch at the upper outside corner of the base section and a tab extending from the upper outside corner of the shorter side section. About one-half of the lamination pieces are aligned adjacent each other to form an upper lamination section. The other half of the lamination pieces are aligned adjacent each other to form a lower lamination section. The upper lamination section is placed on the lower lamination section such that the tabs and corresponding notches are in contact. The height of the tabs and depth of the notches are proportioned such that a gap of preselected width extends between the edge of the upper portion of the side sections and the adjacent portion of the base section.

Abstract: A floodlight housing is provided including a metal casing having top, bottom, side and rear walls. A plurality of elongated fins protrude from the rear wall of the casing to form a heat sink assembly. The entire casing and elongated fins are formed of cast aluminum. The housing is adapted to have an electric lamp and reflector assembly mounted within. The reflector is affixed to one of the walls of the casing in the area of maximum heat concentration from the lamp.

Abstract: A method and apparatus for uniformly cladding a metal wire with a coating of a second metal is provided. The metal wire to be coated is preheated in a non-oxidizing atmosphere to a temperature slightly less than the melting point of the metal coating. The metal coating is present as a molten metal in an atomization chamber. A source of preheated, pressurized, non-oxidizing gas is utilized to inject such gas into spray nozzles. Each spray nozzle also receives molten metal that is drawn into and atomized in the nozzle. The molten metal is thusly sprayed onto the metal wire moving through the atomization chamber.

Abstract: The present invention provides a luminaire fixture having a generally cup shaped upper housing casting. A bowl shaped reflector is mounted thereto. The lower rim of the upper housing includes a flange extending outwardly and downwardly therefrom. The upper surface of the reflector includes a plurality of vent openings near its upper edge. The reflector is fitted to the lower edge of the housing such that the upper housing flange covers the vent openings in the reflector to prohibit rain and snow from entering the reflector. Further, the upper housing includes a rim extension contacting the upper surface of the reflector to seal the upper housing ballast compartment for safety requirements.

Abstract: A lighting fixture is provided having a rear housing and a front housing including a refractor. The rear housing includes a first opening adapted to receive a wiring conduit. The rear housing also has a second opening adapted to receive separate wires for the lighting fixture. The second opening has a boss or rim extending inwardly around its inner edge. The rim is adapted to receive a cover against one of its edges if the separate wires are used and against the other of its edges if the wiring conduit is used to supply electricity to the lighting fixture.

Abstract: A hinge assembly is provided for a lighting fixture whereby a bezel door is hinged to the fixture housing in a manner that it can be swung open from the open face of the housing but cannot be dropped or lose supported contact with the housing. The hinge assembly is located along one edge of the housing. The hinge assembly comprises a hinge hook portion typically an extension of the lower bezel door edge. The hinge hook is an open-faced, open-ended cylindrical structure having a centerpiece with a stud extending therefrom. The hinge bar comprises two axially aligned cylindrical sections extending typically from the lower edge of the housing. The hinge hook is fitted over the hinge bar sections and a fastener is placed over the hinge hook stud.
