Abstract

A photoflash lamp array comprising a plurality of flash lamps having lead-in wires connected to a circuit board, and a reflector unit positioned between the lamps and the circuit board. The reflector unit is made of plastic having an electrically conductive reflecting coating on its front surface, and the reflector unit is shaped to provide openings so that the conductive coating is adjacent to or touching electrical ground areas of circuitry on the circuit board, whereby the reflector unit functions to dissipate electrostatic charges thus preventing accidental flashing of lamps.
