US4500946A — Replaceable lamp assembly for a sealable reflecto…

Claim 1

Independent Claim 204 words

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.

Claim 2

Dependent Claim 204 words

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.

Claim 3

Dependent Claim 54 words

An assembly as in claim 1, wherein said support means comprises a plurality of rigid electrical conductors electrically connected to filament leads extending through the base of said lamp and rigidly mounted within said body portion to locate said filament at said predetermined point and said electrical conductors are permanently connected to said conductors.

Claim 4

Dependent Claim 48 words

An assembly, as in claim 2, wherein said reflector is formed to present a predetermined light radiation pattern, when the filament of said lamp is located and oriented at a predetermined spacial point within said enclosure, and said cylindrical socket is coaxially aligned with said predetermined spacial point.

Claim 5

Dependent Claim 24 words

An assembly as in claim 3, further including coding means for allowing only properly corresponding plug means to be mated with said cylindrical socket.

Claim 6

Dependent Claim 57 words

An assembly as in claim 4, wherein said coding means comprises a plurality of spacially disposed keys and keyways on the respective interior surface of said cylindrical socket and the external surface of said body portion and further wherein said spacial disposition dictates correct plug and socket correspondence as well as the correct orientation of said filament.

Claim 7

Dependent Claim 33 words

An assembly as in claim 5, wherein said sealing means includes an elastomer ring surrounding and retained on said body portion of said plug means between said coding means and said base flange.

Claim 8

Dependent Claim 35 words

An assembly as in claim 6, wherein said outer surface of said body portion of said plug means between said coding means and said base flange contains a circumferential channel for retaining said elastomer ring.

Claim 9

Dependent Claim 151 words

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.

Claim 10

Dependent Claim 151 words

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.

Claim 11

Dependent Claim 54 words

A replaceable lamp plug assembly, as in claim 8, wherein said coding means includes a set of protruding key elements formed on the interior surface of said cylindrical socket in a spaced arrangement and a like set of keyways formed on the outer surface of said plug means for a correctly corresponding filament lamp.

Claim 12

Dependent Claim 46 words

A replaceable lamp plug assembly, as in claim 9, wherein said filament lamp has rigid filament leads extending therefrom and said leads are precisely welded to electrically conducting support rods within said plug means to support said filament lamp in a predetermined orientation within said assembly.

Claim 13

Dependent Claim 37 words

A replaceable lamp plug assembly, as in claim 10, wherein said electrical terminals are male blade terminals connected to said support rods and said plug connector shroud extends beyond said blade terminals to form a receptive opening.
