Abstract
An arrangement provided with a gas and/or steam discharge lamp, the arrangement of which is intended to supply said lamp from an alternating voltage source, in which two input terminals of the arrangement are connected by a series arrangement of at least one stabilizing inductance and the lamp, and in which the lamp is derived by a circuit comprising a controlled semiconductor switch, the semiconductor switch being made conductive through a control circuit at least every second half cycle of the alternating voltage source in the operating condition of the lamp, characterized in that the controlled semiconductor switch can be disconnected with the help of a control voltage in a control electrode of said switch and in that the control circuit of said semiconductor switch includes a branch that has a time constant so short that it makes the switch at least several times conductive and not conductor during each of said half cycles of the alternating voltage source.
