Abstract
Abstract A circuit arrangement for igniting flash tubes, without using an ignition electrode, and having two main electrodes which are supplied with an ignition pulse parallel to a flash capacitor and an electronic switch, employs an electronic switch which also constitutes a gas discharge path. In particular the electronic switch may be realized as a flash tube.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
102 words
A flash arrangement comprising: at least one first gas discharge flash lamp; a flash capacitor; a voltage source connected to charge said flash capacitor; an electronic switch comprising a second flash lamp connected in series with said first flash lamp; the series combination connected across said flash capacitor, said second flash lamp including a gas discharge path, each of said flash lamps comprising only main electrodes, a main electrode of each flash lamp connected to a main electrode of the other flash lamp to define a junction; and an ignition pulse generator connected to the junction of the two interconnected main electrodes.
Claim 2
Dependent Claim
