Photoflash lamp

摘要

A high-voltage type photoflash lamp filled with a filamentary combustible material and oxygen and having an ignition structure comprising a pair of spaced apart lead-in wires bridged at their inner ends by a mass of primer material. An insulating sleeve encloses one of the wires, with the end of that wire extending beyond the open end of the sleeve. Formed at an angle from the other lead-in wire is a terminating portion which overlies and is spaced from the open end of the sleeve to provide a predetermined gap between the terminating portion and the end of the sleeved wire. The primer material is disposed to cover the open end of the sleeve and bridge the gap.
