ABSTRACT:
An incandescent lamp fixture includes an incandescent lamp screwed into a plastic lamp socket, a metallic heat dissipater in intimate heat transfer contact with the socket and having heat dissipating fins extending out from the socket. A metallic reflector surrounds the lamp and is mounted on the dissipater in heat transfer contact with it. An open-ended cylindrical lamp shade is connected to the heat dissipater and is in spaced, concentric relation to the dissipater, socket and lamp to permit free flow of air heated by the fixture to pass between the outside of the reflector and through the fins of the dissipater on the one side and the interior of the shade on the other. This will keep the temperature of the lamp base below the breakdown temperature of the socket and switch and below the breakdown temperature of the cement between the lamp base and the lamp bulb. A switch assembly includes a switch base mounted to the lamp socket and incoming power wires mounted directly on the switch base. A switch toggle and a moving switch contact controlled by the toggle are also directly mounted on the switch base.
