ABSTRACT:
A driving circuit for a low-pressure discharge lamp, particularly a compact fluorescent lamp, features a heating transformer with two separate secondary windings, which are respectively permanently connected to the lamp electrodes, and furnish them with pre-heating current. Parallel to the primary winding of the transformer, there is connected a series circuit of an operating switch, a ballast inductor, and the discharge path formed between the lamp electrodes. The electrodes are connected to each other via a starter connected in parallel to the discharge path.
