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 provided with an electrically conductive reflecting coating on its front surface, and is further provided with an integral tab member having a surface exposed to the front of the reflector unit, which surface is coated with said conductive coating, the tab being bent over so that its coated surface faces the circuit board and is in contact with an electrical ground area of the circuit board, whereby the conductive coating of the reflector unit is connected to electrical ground and functions to dissipate electrostatic charges thus preventing accidental flashing of lamps.
