Abstract: The invention relates to an arrangement for the controllable supply of a lamp which to this end is arranged in series with a controlled semiconductor switching element. According to the invention the control circuit of the semiconductor switching element is equipped with an optoelectronic coupling element. In case of a defect in the control circuit this element prevents the lamp supply voltage from causing damage in this control circuit. In addition the invention provides the possibility of extinguishing the lamp in a simple manner, substantially without a light flash.
