Abstract
Abstract An electrically-activated photoflash lamp unit including a linear array of lamps positioned within a housing which pivots about the unit's coupling means. The coupling means includes an elongated body member having a connector tab at one end thereof for plugging within a camera's socket. Sequential activation of the lamps is provided by flash-activating pulses from the camera's power source which pass up through the elongated body member and pivot location of the housing to each lamp.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
119 words
A foldable photoflash lamp unit for substantially eliminating red-eye photographic results, said lamp unit comprising: a housing including a base portion and a light-transmitting cover portion; an array of electrically-activated flash lamps positioned within said housing; and elongated coupling means including a body portion and a mounting device at a first end of said body portion for mounting atop or within a camera, said coupling means adapted for transmitting flash-activating signals from said mounting device to each of said flash lamps within said housing, said housing pivotally oriented on said coupling means and adapted for occupying first and second positions relative thereto, said flash-activating signals passing through the location of said pivot when said housing occupies said first position.
Claim 2
Dependent Claim
119 words
A foldable photoflash lamp unit for substantially eliminating red-eye photographic results, said lamp unit comprising: a housing including a base portion and a light-transmitting cover portion; an array of electrically-activated flash lamps positioned within said housing; and elongated coupling means including a body portion and a mounting device at a first end of said body portion for mounting atop or within a camera, said coupling means adapted for transmitting flash-activating signals from said mounting device to each of said flash lamps within said housing, said housing pivotally oriented on said coupling means and adapted for occupying first and second positions relative thereto, said flash-activating signals passing through the location of said pivot when said housing occupies said first position.
Claim 3
Dependent Claim
13 words
The photoflash lamp unit according to claim 1 wherein said array is linear.
Claim 4
Dependent Claim
29 words
The photoflash lamp unit according to claim 2 wherein said housing is substantially prependicular to said body portion of said coupling means when said housing occupies said first position.
Claim 5
Dependent Claim
28 words
The photoflash lamp unit according to claim 2 wherein said housing is substantially parallel to and immediately adjacent said body portion when said housing occupies said second position.
Claim 6
Dependent Claim
37 words
The photoflash lamp unit according to claim 1 further including a reflector positioned within said housing relative to each of said flash lamps for enhancing the light output from said flash lamp toward said light-transmitting cover portion.
Claim 7
Dependent Claim
39 words
The photoflash lamp unit according to claim 1 wherein said coupling means further includes an electrically conductive rod member located within a second end of said body portion opposite said first end, said housing pivoting about said rod member.
Claim 8
Dependent Claim
28 words
The photoflash lamp unit according to claim 6 wherein said coupling means further includes a fixed electrical contact located within said body portion adjacent said conductive rod member.
Claim 9
Dependent Claim
41 words
The photoflash lamp unit according to claim 7 wherein said mounting device comprises a connector tab including first and second conductive terminals thereon, said first and second conductive terminals electrically joined to said conductive rod member and said electrical contact, respectively.
Claim 10
Dependent Claim
51 words
The photoflash lamp unit according to claim 7 further including a circuit board within said housing having lamp-firing circuitry thereon electrically connected to said conductive rod member and said fixed electrical contact when said housing occupies said first position, each of said flash lamps electrically connected to said lamp firing circuitry.
Claim 11
Dependent Claim
59 words
The photoflash lamp unit according to claim 8 wherein said coupling means further includes first and second elongated conducting leads located within said body portion, said first conducting lead electrically connecting said first terminal within said connector tab to said rod member, said second conducting lead electrically connecting said second terminal with said connector tab to said electrical contact.
Claim 12
Dependent Claim
40 words
The photoflash lamp unit according to claim 1 further including a stop member located on said base portion of said housing for engaging said body portion of said coupling means to stop said housing at said first and second positions.
