ABSTRACT:
A sheet metal housing for an HID luminaire which comprises a two piece, fold-up sheet metal housing which provides exceptional strength with minimal usage of materials to support a very heavy ballast therein. The sheet metal housing is suitable for a low cost highbay luminaire with high watt ballasts for Metal Halide and High Pressure Sodium, Mercury Vapor (HID) light sources. The sheet metal housing provides reflector adjustability for different size lamps and light centers. A top sheet metal stamping defines a central ballast shelf on which a ballast is mounted, and first and second ends of the top stamping are bent 90.degree. on opposite sides of the central ballast shelf. The first and second ends of the top stamping are further bent back 180.degree. upon themselves to form a double wall. The first and second ends of the top stamping are further bent 90.degree. to project towards each other. The very ends of the first and second ends of the top stamping are further bent and interconnected to form a three wall top hanging system, and to form a top sheet metal housing. First and second ends of a bottom sheet metal stamping are bent 90.degree. about a central section to form a bottom sheet metal housing.
