Abstract (en)
[origin: CA2366894A1] The invention relates to a circuit arrangement for operating electric lamps, the circuit arrangement having an inverter for generating a medium or high- frequency supply voltage for one or more lamps (21) and a starting circuit for the inverter, and also a device for deactivating the starting circuit, the starting circuit comprising a voltage-dependent switching element (34) and a capacitor (33), and the device for deactivating the starting circuit comprising a switching means (35) whose switching path is arranged in parallel with the capacitor (33) of the starting circuit. According to the invention, the device for deactivating the starting circuit has a threshold switch (39) for controlling the switching means (35).
