ABSTRACT:
A flash lamp array having a plurality of high-voltage flash lamps in front of a reflector unit and a circuit board behind the reflector unit and carrying a plurality of circuit runs of relatively high resistance inexpensive material such as powered carbon and including a common or "ground" circuit run connected to a lead-in wire of each lamp. A shield is positioned behind the circuit board and is connected to the common circuit run near a connector tab at an end of the circuit board. This reduces the possibility of accidental flashing of lamps by electrostatic electricity.
