Abstract
A reusable lens/reflector unit is formed to accept a molded plastic replaceable lamp plug assembly formed to provide a hermetic seal for the lens/reflector unit. Internal sealing of electrodes within the lamp plug assembly provides electrical interconnection and mechanical support for the lamp bulb in a predetermined position. Coding means provides that only designated lamp plug assemblies may be mated with appropriate lens/reflector units.
Claims11
A replaceable lamp plug assembly for mating with a hermetically sealable lamp enclosure including a light transmitting lens, attached to the front of a light directing reflector and an open cylindrical socket formed to extend outwardly from the rear of said reflector comprising:
- a filament lamp light source;
- and
- plug means having a body portion formed to be axially inserted into said cylindrical socket wherein said plug means includes means for permanently supporting said lamp so that the filament of said lamp is located at a predetermined point and in a predetermined orientation with respect to said body portion;
- means for hermetically sealing said lamp enclosure when said plug means is inserted into the rear of said cylindrical socket;
- a base flange extending transverse to said body portion and having a diametric dimension larger than that of said cylindrical socket for contacting the outward extension of said cylindrical socket and limiting the insertion distance of said plug means into said socket;
- a plurality of electrical terminals permanently connected through said body portion to said filament of said lamp;
- and a plug connector shroud on the opposite end of said plug means from said support means, extending beyond said base flange and surrounding said terminals.
A replaceable lamp plug assembly for insertion into a cylindrical socket extending from the rear of a focused reflector enclosure comprising:
- an encapsulated filament lamp;
- plug means for supporting said filament lamp in a predetermined position;
- means on said plug means for providing a hermetic seal between the interior surface of said cylindrical socket opening and said plug means when said plug means is inserted into the rear of said cylindrical socket;
- coding means for allowing the insertion of a correctly corresponding filament lamp of said assembly into said socket opening and precisely locating its filament with respect to a predetermined piont in said enclosure;
- a plurality of electrical terminals permanently connected to the filament of said filament lamp and extending through said plug means;
- and
- a terminal shroud on the opposite end of said plug means from said support means extending away from said filament lamp and surrounding said terminals.
