Abstract
A circuit arrangement for igniting at least one gas discharge flash tube having two main electrodes includes a chargeable flash capacitor connected in parallel with the flash tube and an electronic switch. These elements are connected to a voltage generator which supplies ignition voltage pulses and the electronic switch constitutes a gas discharge path for the flash tube. The voltage generator has such a low impedance, in particular a low inductance, that the ignition voltage pulses supplied thereby at least approximately adiabatically heat the gas discharge paths.
Claims8
In a flash arrangement of the type wherein a chargeable flash capacitor is connected in a charging path and in parallel with a plurality of serially-connected electronic gas discharge devices including at least one flash tube which has only two electrodes for supporting both ignition and discharge, and wherein the flash tube is connected via an electronic switch to a voltage generator which supplies ignition pulses, the electronic discharge devices constituting a discharge path for said flash capacitor and the electronic switch constituting an ignition switch, the improvement, in combination therewith, wherein:
- said voltage generator comprises a low internal impedance which causes the ignition voltage pulses to at least approximately and rapidly adiabatically heat the plasma channel produced in the flash tube of the gas discharge path.
