Abstract (en)

[origin: EP0399201A1] In a flashlight warning system with a voltage source, with an isolating transformer, with two storage capacitors, with a flash tube, with a starting circuit and with an electrical switch in series with the first storage capacitor, the switch can be controlled electrically. Furthermore, an electrical voltage sensing device is provided, which determines the charge voltage of the first storage capacitor, compares this voltage with a predetermined reference voltage and opens the switch when the charge voltage exceeds the reference voltage. These measures have the object of providing a flashlight warning system which can be produced simply and cost-effectively and which, with reliable starting of the flash tube, permits extensive influencing of the energy or flashlight intensity of the light flash which is generated. <IMAGE>
