ABSTRACT:
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. An electrically conductive reflector unit is positioned between the lamps and the circuit board. The reflector unit is connected to the common circuit conductor by means of a pliable, electrically conductive adhesive material, whereby the reflector unit functions as an electrical shield for the circuitry.
