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. The circuit board has an integral connector tab with a pair of terminals on one side connected to the igniting circuitry. 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. The conductive shield is shaped with a portion thereof extending toward the end of the connector tab on the side opposite from the terminals to provide a discharge path for electrostatic charges in proximity to the tab. Preferably the shield extension is narrower than the tab and fits within a slotted recess therein between the tab and a back housing member.
