ABSTRACT:
An electronic starter for a fluorescent lamp comprises a power switch, controlled at its gate by a gate-control circuit and an auxiliary supply circuit that gives the necessary logic supply voltage to the gate-control circuit on a terminal of a capacitor. The gate-control circuit comprises a comparator with two voltage references to measure a duration of preheating of the lamp, the input of this comparator receiving the logic voltage given by the capacitor, the output of the comparator being used to command the closing or the opening of the switch. In one improvement, there is provided a preheating current measurement circuit to detect the optimum current for lighting up the lamp once the necessary preheating time has elapsed.
