Abstract
A metal housing of a light fixture has a cover hinged over the front access opening. Within the housing is a halogen lamp or light bulb. Surrounding the lamp and facing forwardly is a reflector of generally parabolic shape. Extending across the back of the reflector parallel to the lamp is a forwardly extending ridge. A glass is held in the cover by clips frictionally engaged in pockets spaced about the inside of the cover. The cover hinge is formed by parts on the cover and housing, which parts are of generally "U" configuration. The pivot pin extends through the U of these parts. The parts are so positioned with respect to each other and stops are provided so as to prevent the disengagement of the pins by movement through the open end of the U. Within the housing are heat sinks to protect the lamp sockets.
