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 powdered carbon and including a common or 'ground' circuit run connected to a lead-in wire of each lamp. The common circuit run is made wider than the other circuit runs, and preferably covers a major portion of the circuit board area. This reduces the possibility of accidental flashing of lamps by electrostatic electricity.
