Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
173 words
A photoflash lamp array comprising: a base member; electrical connection means; and a plurality of lamp-reflector units, each of said units comprising a photoflash lamp mounted on said base member and a reflector within which each of said lamps is disposed; said electrical connection means for selectively connecting said lamps to flash-initiating means; said array comprising a first group of a plurality of said lamp-reflector units mounted in a row on said base with their reflectors facing in a first direction, and a second group of a plurality of said lamp-reflector units mounted in a row on said base with their reflectors facing in substantially the opposite direction from that of said first group of reflectors; the lamps of each group of lamp-reflector units in said array being staggered relative to the lamps of the other group, and all the reflectors of each group of lamp-reflector units being constituted of a single piece of material with the reflectors of said first group nested in back-to-back relation with the reflectors of said second group.
Claim 2
Dependent Claim
173 words
A photoflash lamp array comprising: a base member; electrical connection means; and a plurality of lamp-reflector units, each of said units comprising a photoflash lamp mounted on said base member and a reflector within which each of said lamps is disposed; said electrical connection means for selectively connecting said lamps to flash-initiating means; said array comprising a first group of a plurality of said lamp-reflector units mounted in a row on said base with their reflectors facing in a first direction, and a second group of a plurality of said lamp-reflector units mounted in a row on said base with their reflectors facing in substantially the opposite direction from that of said first group of reflectors; the lamps of each group of lamp-reflector units in said array being staggered relative to the lamps of the other group, and all the reflectors of each group of lamp-reflector units being constituted of a single piece of material with the reflectors of said first group nested in back-to-back relation with the reflectors of said second group.
Claim 3
Dependent Claim
26 words
A photoflash lamp array according to claim 1 in which said lamps are substantially tubular and have their longitudinal axes substantially perpendicular to said base member.
Claim 4
Dependent Claim
46 words
A photoflash lamp array according to claim 1 in which insulation means are provided between the reflectors of said first group and the reflectors of said second group whereby distortion of adjacent reflectors upon the flashing of a lamp in one of said units is minimized.
Claim 5
Dependent Claim
49 words
A photoflash lamp array according to claim 1 in which means are provided for the vertical flow of convection currents of air to cool the reflectors upon flashing of the lamps so as to minimize distortion of adjacent reflectors upon flashing of a lamp in one of said units.
Claim 6
Dependent Claim
29 words
A photoflash lamp array according to claim 1 in which said electrical connection means comprise a contact board having electrical contact strips on at least one of its surfaces.
Claim 7
Dependent Claim
73 words
A photoflash lamp array according to claim 5 in which said contact board has on one side a common contact connected to one lead of each of the lamps of said first group and also has on said first side a separate lead for each of said lamps of said first group, and the reverse side of said contact board has a like arrangement for each of the lamps of said second group.
Claim 8
Dependent Claim
23 words
A photoflash lamp array according to claim 1 in which said electrical connection means comprises two electrical contacts for each of said lamps.
Claim 9
Dependent Claim
32 words
A photoflash lamp array according to claim 1 in which a plurality of the said nested groups of lamp-reflector units are arranged in a plurality of layers located one on top another.
Claim 10
Dependent Claim
119 words
A photoflash lamp array according to claim 1 in which: insulation means are provided between the reflectors of said first group and the reflectors of said second group whereby distortion of adjacent reflectors upon the flashing of a lamp in one of said units is minimized, and said electrical connection means comprise a contact board having electrical contact strips on each side comprising a common contact connected to one lead of each of the lamps of said first group and also has on the same side a separate lead for each of said lamps of said first group, and the reverse side of said contact board has a like arrangement for each of the lamps of said second group.
Claim 11
Dependent Claim
24 words
A photoflash lamp array according to claim 1 in which a protective light-transmitting cover is provided over the said nested groups of lamp-reflector units.
