Abstract (en)

In a flash lamp, it is intended to increase the energy density with respect to the prior art. The composition of the hard glass is selected such that its components which vaporise easily during the discharge are at least partially emitter materials which reduce the work function at the cathode body (5). <IMAGE>

Abstract (de)

Bei einer Blitzlampe soll die Energiedichte gegenüber dem Stand der Technik gesteigert werden. Die Zusammensetzung des Hartglases ist so gewählt, daß dessen bei der Entladung leicht verdampfende Komponenten mindestens teilweise Emitterstoffe sind, die an dem Kathodenkörper (5) die Austrittsarbeit herabsetzen.
