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. A flange extends from the lamp plug body and is clamped against the socket by a rotatable collar that threads onto the socket to surround the flange and the socket.
Claims9
A replaceable lamp assembly for mating with a hermetically sealable lamp enclosure including a light transmitting lens, a light directing reflector and a socket opening in said reflector comprising:
- a filament lamp light source;
- plug means, containing said filament lamp, and having a body portion formed to be axially inserted into said socket opening, wherein said plug means includes means for 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, and means for sealing said lamp enclosure when said plug means is inserted into said socket opening;
- a base flange extending transverse to said body portion and having a diametric dimension larger than that of said socket opening for limiting the insertion distance of said plug means into said socket opening;
- and
- means surrounding said base flange of said plug means and said socket for locking said plug means in said socket.
A replaceable lamp assembly for insertion into the rear socket of the focused reflector enclosure comprising:
- an encapsulated filament lamp;
- plug means for supporting said filament lamp in a predetermined position;
- means for providing a hermetic seal between said rear socket and said plug means;
- coding means for allowing the insertion of a correctly corresponding filament lamp of said assembly to said socket and precisely locating its filament with respect to a predetermined point in said enclosure;
- and
- means for threadably clamping said plug means within said rear socket.
