Circuit arrangement for the AC operation of gas-discharge lamps

摘要

A circuit arrangement for the AC operation of gas-discharge lamps, in which the lamp (2) is connected to an AC source in series with a current limiter (1) and a power-reduction circuit, the power-reduction circuit having a two-directional semiconductor switching element (3) in parallel with which there is connected a capacitor (4) in series with a voltage-dependent resistor (5) (VDR). <IMAGE>
