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. 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.
