Electric lamp having an internal switching mechanism

摘要

A combustion flash lamp having a number of lead-in conductors in which two of the lead-in conductors are surrounded over a part of their length dimension by a metal sleeve which melts around said conductors as a result of the thermal energy released upon firing the lamp and interconnects them electrically. The lamp is suitable for use in a flash lamp cube in which the lamps can be fired one after the other.
