Abstract
Abstract A flash lamp array, such as the Flip Flash type, having a plurality of flash lamps positioned in front of a circuit board which has connector terminals thereon. One connector terminal is connected in common to a lead wire of each of a plurality of lamps by means of a metal shield behind the circuit board. The common terminal is connected, by a circuit run, to a lead wire of the nearest lamp; this lead wire and a lead wire of each of the other lamps extend back from the circuit board and contact the shield thus connecting the lead wire and the shield to the common terminal.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
140 words
A photoflash lamp array comprising a circuit board provided with a set of first and second terminals for connection to a source of lamp-firing voltage pulses, a plurality of flash lamps arranged in a planar configuration, forwardly of said circuit board, and an electrically conductive shield positioned behind and parallel to said circuit board, wherein the improvement comprises a circuit run on said board which directly connects said first terminal with one lead-in wire of a first one of said lamps only, said one lead-in wire and also a lead-in wire of each of the other lamps extending rearwardly and contacting said shield, whereby said lead-in wire of each lamp and said shield are electrically connected to said first terminal, said circuit board being devoid of circuit runs to said lead-in wires of each lamp other than said first lamp.
Claim 2
Dependent Claim
140 words
A photoflash lamp array comprising a circuit board provided with a set of first and second terminals for connection to a source of lamp-firing voltage pulses, a plurality of flash lamps arranged in a planar configuration, forwardly of said circuit board, and an electrically conductive shield positioned behind and parallel to said circuit board, wherein the improvement comprises a circuit run on said board which directly connects said first terminal with one lead-in wire of a first one of said lamps only, said one lead-in wire and also a lead-in wire of each of the other lamps extending rearwardly and contacting said shield, whereby said lead-in wire of each lamp and said shield are electrically connected to said first terminal, said circuit board being devoid of circuit runs to said lead-in wires of each lamp other than said first lamp.
Claim 3
Dependent Claim
23 words
An array as claimed in claim 1, in which said first lamp is that which is relatively nearest to said set of terminals.
Claim 4
Dependent Claim
157 words
An array as claimed in claim 1, of a dual type such as a Flip Flash array, in which said set of terminals is at one end thereof and including a second set of first and second terminals at the other end thereof, circuit means connecting the first terminal of the first set thereof to a first group of said lamps relatively nearer to said second set of terminals than to the first set of terminals, circuit means connecting the first terminal of said second set thereof to a second group of said lamps relatively nearer to said first set of terminals than to said second set of terminals, said circuit run connecting said first terminal of the first set thereof to a first lamp in said second group of lamps, and another circuit run on said board connecting said first terminal of the second set thereof to a first lamp in said first group of lamps.
Claim 5
Dependent Claim
50 words
An array as claimed in claim 3, in which said first lamp of the second group thereof is that which is relatively nearest to said first set of terminals and said first lamp of the first group thereof is that which is relatively nearest to said second set of terminals.
