Subminiature photoflash lamp having light-emitting pyrotechnic charge

摘要

A subminiature photoflash lamp which includes a pyrotechnic charge centrally disposed within the lamp's plastic, light-transmitting envelope. The charge is supported on the ends of the lamp's ignition means and is of a disklike, planar configuration to provide maximum light output. Ignition of the lamp can be achieved by application of a firing pulse from a piezoelectric element.
