Abstract (en)
[origin: DE19544842A1] The invention concerns a high-pressure gas-filled discharge lamp (10) connected at one end via the secondary winding (9) of a starter transformer (11) to a line (12), and at the other end to a second line (13). The ignition energy is supplied in the form of a pulse. To this end, a controllable switch (6) is connected in series with the primary winding (7), the switch being conductive when a particular voltage is reached or being switched on by a control unit (8). Connected in parallel with the series-connected circuit is a capacitor (5) which is charged up, through a resistor (3) connected in series with it and a diode (4), by the voltage U between the input terminals (12, 13). The invention calls for a circuit to be connected between the input terminals of the starter to provide protection against voltage peaks, the input circuit consisting of a capacitor (1) or a protective element (2) or a combination of the two.
