Abstract
A flash array provided with a number of high voltage combustion flash lamps which are ignited by means of a piezo element. The flashing of two lamps at the same time is prevented by means of melting strips. According to the invention the igniting pulse for a second lamp of the device is passed on via a capacitive circuit element which is formed by the flashed first lamp or a separate capacitor. By using such a capacitor circuit element instead of an ohmic resistance undesired loss of heat is avoided.
