Abstract (en)

[origin: WO2008064715A1] The present invention relates to a circuit arrangement and corresponding method for igniting a high-pressure discharge lamp (LA), comprising a main combustion chamber (HaBK) with a first and a second main electrode (HaE1, HaE2) and an auxiliary combustion chamber (HiBK), with an inverter (10), a control circuit for controlling the electronic switches (S1, S2, S3, S4) of the inverter (10), an auxiliary ignition circuit (14), comprising: a first and a second input connection (ZE1, ZE2), a first output connection (ZA1) for connecting the first main electrode (HaE1) of the high-pressure discharge lamp (LA), a second output connection (ZA2) for connecting the second main electrode (HaE2) of the high-pressure discharge lamp (LA), and an auxiliary electrode (HiE) for inducing an auxiliary ignition voltage in the auxiliary combustion chamber (HiBk). The auxiliary electrode (HiE) is arranged on the side of the first output connection and the auxiliary ignition circuit (14) comprises a cascade circuit, which at the output thereof provides a voltage for igniting the high-pressure discharge lamp (LA).
