Abstract

A device for priming and feeding a gas and/or vapor light discharge lamp, which is provided with two electrodes, the device being provided with two input terminals, which are intended to be connected to a current voltage source alternating, whose frequency is less than 100 c/s, the two input terminals -during priming and powering the lamp- interconnected by means of a series circuit comprising at least one stabilization inductance and the lamp, while that the two electrodes of the lamp are interconnected by means of a primer comprising a first semiconductor switching element, while, in parallel with a branch comprising said semiconductor switching element, a control circuit of the first switching element is provided semiconductor, that control circuit comprising at least a first capacitor, an auxiliary primer transistor deriving from at least to the first capacitor, while the base of the auxiliary transistor is connected to a control circuit, namely, to a junction of a first resistance and a second capacitor, which are connected in series and are in parallel with the branch comprising the first semiconductor switching element, characterized in that the base of the auxiliary transistor is connected, through a voltage sensitive threshold element, to the junction of the resistance and the second capacitor, and that the electrodes of the lamp They are connected by a third capacitor and because a second inductance is included in the connection with the lamp electrodes to the first semiconductor switching element.
