Abstract
A multiple photoflash system is provided which employs a high voltage type flashlamp construction, including a shorting primer material. Said primer material is converted to a conductive residue upon ignition of flashlamp to provide a short circuit path between spaced apart inleads of the lamp. Further series connection of the individual lamps in the flashlamp system which are operatively associated with switching devices to provide an open circuit condition upon flashing of the associated lamps permits sequential flashing. The particular primer material which enables the flashlamp system to be operated in this manner comprises a solid mixture of a combustible metal fuel and an oxidizer for the fuel such as alkaline metal chlorates and perchlorates, and which further contains particular proportions of various combustion supporting oxides.
