Abstract
A fluorescent lighting fixture having a novel attachment and engaging means, thereby reducing the number of components needed for the manufacture of the lighting fixture, concomitantly reducing the assembly time and assembly costs. The attachment means is comprised of a ballast housing having a threaded portion that engages the mating threaded indentations found the base of the lighting fixture. The ballast housing is rotatably drawn flat, abutting the surface of the fixture base into a binding frictional engagement. A lamp support bracket, securely attached to the end of the ballast housing opposite its mounting base, is bat-winged shaped to allow the fluorescent lamp to be positioned close to the base of the lighting fixture to permit a stylized dome-shaped cover to be snap-fitted to the base of the fixture. The dome-shaped cover, having a circumferential ridge on its skirt, is securely held in place by snapping the cover past three nibs in the base plate, spaced preferably 120 degrees apart.
