ABSTRACT:
A control circuit comprising a thyristor and a feedback circuit formed by an inductance and a generator for producing electrical energy in response to a luminous event. The feedback circuit controls the conducting or cut-off state of the thyristor by the fact that a trigger-gate of the thyristor is connected to a terminal of the generator having a polarity cutting off the thyristor when the generator is illuminated. The thyristor is switched on in response to an energy stored in the inductance, which energy is caused by a sudden discontinuity of the luminous event.
