ABSTRACT:
An improved primer material is disclosed for a high-voltage type flashlamp construction. Said primer material comprises a solid mixture of a combustible fuel and an oxidizer for the fuel such as alkali metal chlorates and perchlorates, and which further contains a combustion-supporting oxide of the type which is converted to a lower oxide upon combustion of the mixture. An all glass flashlamp construction is disclosed in which the improved primer material can be disposed between a pair of spaced apart inlead wires to provide suitable ignition means for the combustion of a quantity of filamentary combustible material distributed within the lamp envelope.
