Abstract
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. A plurality of reflectors respectively associated with the flashlamps are disposed between the lamps and circuit board, with each reflector having an aperture in alignment with a corresponding aperture in the circuit board. Connected in series with each but the last lamp of the array is a radiant-energy-activated quick-disconnect switch comprising a strip of electrically conductive heat shrinkable, polymeric material which is attached at both ends to the circuit board so as to bridge a respective one of the apertures therein. Upon ignition of its associated flashlamp, each disconnect switch is operative in response to the resulting radiation through the aperture aligned therewith to rapidly provide a reliable open circuit to high voltages, thereby permitting reliable flashing of the lamps in rapid succession.
