ABSTRACT:
A heat-dissipating light fixture for use with a tungsten-halogen lamp has an externally finned metal body provided with an internal cavity divided into two opposite portions by an integrally formed heat shield having a socket opening formed therethrough. An electrical connector is secured to one side of the heat shield, over the socket opening, and a graphite foil disc is secured to the other side of the heat shield, the foil disc having central tab portions which overlie the socket opening. The lamp is installed in the fixture by pressing the lamp base portion through the foil disc and the socket opening until the connecting prongs of the lamp enter prong openings in the connector. Insertion of the lamp base into the socket opening bends the foil tabs into the opening where they are compressed between the lamp base and the interior surface of the socket opening. The heat shield intercepts and absorbs infrared radiation generated by the lamp reflector toward the connector. Additionally, heat from the lamp base is conducted, via the foil tabs, to the heat shield. The heat transmitted to the heat shield is conducted outwardly therethrough to the fixture body and dissipated by the fins thereon to surrounding ambient air, thereby protecting the lamp and its connector from excessive heat build-up.
