Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
151 words
A lamp assembly for flash illuminating a document to be reproduced on a reproduction machine comprising: a reflector; dielectric clamp means mounted on said reflector, said clamp means having a contoured surface formed thereon for engagement with one side of a tubular arc discharge lamp, said clamp means including spring clip means disposed opposite said contoured surface, said spring clip means having a shoulder formed thereon; a tubular arc discharge lamp, said lamp being retained in the lamp assembly between said contoured surface and said spring clip in a predetermined position relative to said reflector by said spring clip means; and a trigger wire positioned along side said lamp parallel to the axis thereof, said wire being looped around said spring clip and retained thereon by said shoulder, said shoulder positioning said wire along side said lamp at the desired location on the periphery of said lamp relative to said reflector.
Claim 2
Dependent Claim
151 words
A lamp assembly for flash illuminating a document to be reproduced on a reproduction machine comprising: a reflector; dielectric clamp means mounted on said reflector, said clamp means having a contoured surface formed thereon for engagement with one side of a tubular arc discharge lamp, said clamp means including spring clip means disposed opposite said contoured surface, said spring clip means having a shoulder formed thereon; a tubular arc discharge lamp, said lamp being retained in the lamp assembly between said contoured surface and said spring clip in a predetermined position relative to said reflector by said spring clip means; and a trigger wire positioned along side said lamp parallel to the axis thereof, said wire being looped around said spring clip and retained thereon by said shoulder, said shoulder positioning said wire along side said lamp at the desired location on the periphery of said lamp relative to said reflector.
Claim 3
Dependent Claim
50 words
A lamp assembly according to claim 1 wherein said clamp means includes a wire mounting stud, said trigger wire being attached thereto, said clamp having a recess formed therein, said wire being routed from said stud through said recess around said clip under said shoulder and along side said tube.
Claim 4
Dependent Claim
59 words
A lamp assembly according to claim 2 wherein said clamp means includes a threaded metallic insert formed therein spaced from said clip, said insert being recessed from the surface of said clamp; and dielectric screw means, adapted for insertion through said reflector for threaded engagement with said insert to fasten said clamp means in position on said reflector means.
Claim 5
Dependent Claim
35 words
A lamp assembly according to claim 1 wherein said trigger wire is formed of a non-magnetic material to prevent movement thereof relative to said lamp by the magnetic force generated by energization of said lamp.
