Abstract (en)

An electronic starting device (1) for fluorescent discharge lamps, highpressure lamps and the like which is meant to be connected downstream of at least one discharge lamp (2) which is connected to the AC supply mains by means of a ballast (3), the particularity of which is the fact that it comprises a rectifier bridge (5) which is connected to first pins of the at least one lamp, a Zener diode (6) and a first resistor (7) which are series-connected to the rectifier bridge, and a circuit portion which is constituted by a first capacitor (8) and a second capacitor (11) to which a second resistor (9) and a third resistor (12) are respectively parallel-connected, a diac (13) which is series-connected to the second capacitor (11), and a third capacitor (14) to which a fourth resistor (15) is parallel-connected, switching means (10) being provided which are connected to the circuit portion and to the rectifier bridge, the switching means being connected to the diac (13) by means of a first terminal, to the first capacitor (8) by means of a second terminal and to the rectifier bridge (5) by means of a third terminal, the third capacitor (14) and the fourth resistor (15) being connected between the first terminal and the second terminal. <IMAGE>
