Abstract (en)
[origin: EP0431695A1] The invention relates to a high-pressure discharge lamp (2) provided with an ignition circuit (10) which comprises a voltage-dependent capacitor (8). According to the invention, a voltage-dependent resistor (9) is connected in series with the capacitor. This realizes both a favourable moment of generation of a voltage pulse and a limitation of the level of the generated voltage pulse in a simple and reliable way. <IMAGE>
