Abstract
A photoflash lamp array comprising a housing elongated vertically and containing elongated flash lamps lying horizontally and stacked vertically, the flash lamps having lead-in wires extending from ends thereof near the sides of the housing and connected to a circuit board located behind the lamps. A conductive sheet-like shield is positioned between the circuit board and the rear of the housing and is contoured to have side portions extending frontwardly and between the lamp ends and the sides of the housing. Electrically insulative flash indicator material is positioned on the front surface of the shield and extends along the inside surfaces of the shield's frontwardly extending portions so as to prevent the lamp's lead-in wires from becoming shorted against the shield.
