摘要： A photoflash unit comprising a linear array of flashlamps mounted on a printed circuit strip disposed within the longitudinal channel of an elongated housing member. A light-transmitting cover panel is attached to the housing member for enclosing the flashlamps. To prevent sympathetic ignition of adjacent lamps, the one-piece cover is molded to have integrally projecting transverse webs which function as light-attenuating partitions between respective pairs of lamps. In addition, the webs bridge the housing channel to provide structural rigidity.

摘要： A photoflash lamp array comprising a plurality of high-voltage type flashlamps mounted on a printed circuit board containing circuitry for sequentially igniting the flashlamps in response to successive high-voltage firing pulses applied thereto. Each of the flashlamps has a pair of lead-in wires connected to the circuit board by eyelets which project through to the opposite side of the board, one lead of each lamp being connected via its respective eyelet to a common circuit conductor. Electrostatic protection is provided by a conductive shield of planar configuration disposed parallel to the circuit board and spaced therefrom on the side opposite that on which the lamps are disposed. Selected ones of the common circuit connected eyelets project from the back of the circuit board in a manner which maintains the spacing between the shield and circuit board, to prevent short circuiting of leads, and facilitates electrical connection of the planar shield to the common circuit conductor.

摘要： A photoflash unit comprising a linear array of flashlamps mounted on a printed circuit board disposed within the longitudinal channel of an elongated housing member having an enclosing cover panel of light-transmitting material. The lamp-firing circuitry includes a common circuit conductor run connected to one lead-in wire of each of the lamps. The housing member includes reflector cavities adjacent to the lamps, and a continuous coating of electrically conductive reflective material covers the surfaces of the channel and reflector cavities for providing both reflective surfaces for flashing lamps and, by virtue of a connection between the common run and conductive coating, a shield to reduce the likelihood of accidental flashing of lamps by electrostatic charges. Additional protection against electrostatic charges is provided by a plurality of tapered holes in the wall of the housing channel through which the continuous conductive coating extends to the exterior surface of the housing, thereby extending electrical ground to the exterior of the unit.

摘要： A photoflash unit comprising a horizontal linear array of flashlamps enclosed within a one-piece housing member having a light-transmitting front portion folded over a back portion containing a plurality of lamp-receiving cavities in which respective lamps are disposed. The housing is a formed sheet of plastic film having a linear fold disposed horizontally along the top of the array of cavities, which are selectively aluminized to provide a reflective coating on the cavity surfaces. A pair of lead-in wires from each of the lamps are connected to conductive circuit patterns on one side of a printed circuit board sandwiched between a set of tabs which run along the bottom of the front and back portions of the housing and are secured together. The sides of the housing are also secured so that the lamps, lead-in wires and connections are disposed within a secured enclosure, with a plurality of conductive connector terminals being disposed on a tab which projects from the printed circuit board and extends exteriorly of the secured enclosure.

摘要： A multilamp photoflash array with lamp-reflector units in linear rows facing in opposite directions and nested back-to-back. The rows of reflectors for both sides of the array are vacuum-formed from a single sheet web between the reflector rows for providing a spring-hinged center support. Each reflector has a parabolic surface with an elongated cylindrical recess behind its associated tubular lamp whereby an air space is provided between the reflector and lamp which functions as a thermal insulator for minimizing heat distortion of adjacent reflectors upon flashing of the lamp.

摘要： A photoflash unit comprising a plurality of high-voltage type flashlamps mounted on a printed circuit board containing circuitry for sequentially igniting the flashlamps in response to successive high-voltage firing pulses applied thereto. One lead-in wire of each of the flashlamps is connected to a common circuit conductor. Electrostatic protection is provided by a conductive array of reflectors positioned between the lamps and one side of the circuit board and a planar shield of conductive material disposed parallel to and spaced from the opposite side of the circuit board, both the reflector array and shield being electrically connected to the common circuit conductor and thereby effecting a static "grounding" system. The assembly is enclosed in a plastic housing having a light-transmitting side wall adjacent to the flashlamps. The present disclosure additionally provides static grounding protection for the front face of the unit by means of conductive elements which project from the reflector array and protrude through respective openings in the light-transmitting side wall of the housing.

摘要： A photoflash unit comprising a linear array of flashlamps mounted on a printed circuit strip disposed within the longitudinal channel of an elongated housing member. A light-transmitting cover panel is attached to the housing member for enclosing the flashlamps, and the circuit strip extends beyond the cover panel to expose connecting terminals. The lamps have tubular envelopes and are positioned with their longitudinal axes substantially parallel to the printed circuit strip and arranged in substantially coaxial alignment. The housing member includes ledges within the channel for spacing the printed circuit strip from the rear wall, and the sidewalls of the channel have guide ribs for engaging notches in the circuit strip for facilitating assembly and location and avoiding longitudinal shifting of the strip. The housing member further includes reflector cavities adjacent to the lamps, and a continuous coating of electrically conductive reflective material covers the surfaces of the channel and reflector cavities for providing both reflective surfaces for flashing lamps and a shield to reduce the likelihood of accidental flashing of lamps by electrostatic charges. In a preferred embodiment, the unit has connector terminals at opposite ends, and the linear array of flashlamps is divided into two groups disposed in opposite halves of the unit, each group of lamps being operated by the connector terminals at the remote end so as to reduce the red-eye photographic effect.
