Definitions

  • the invention relates to a circuit arrangement for operating a discharge lamp according to the preamble of patent claim 1.
  • the circuit arrangement according to the invention has the decisive advantage that the voltage is automatically reduced disproportionately in the case of short-circuit operation and the current in the case of excessively high voltage.
  • the working range of the circuit arrangement according to the invention in which the lamp power is almost constant is expanded by using a second operational amplifier, which is connected as a comparator and effects an operating point switchover as a function of the lamp operating voltage.
  • a second operational amplifier which is connected as a comparator and effects an operating point switchover as a function of the lamp operating voltage.
  • differences in the lamp operating voltage which are caused by production or by the aging process of the discharge lamps, can be compensated for.

  • this second embodiment has a relatively high stability against temperature fluctuations.
  • the working range of the circuit arrangement according to the invention is expanded by using a Zener diode which is arranged in parallel with the first voltage divider, so that manufacturing or age-related variations in the lamp operating voltage can also be compensated for here.

  • the circuit arrangement here has a DC voltage source U Batt , a switched-mode power supply SNT, an inverter WR, an igniter ZG, a discharge lamp L, a control circuit ST and a circuit part ADD for detecting the lamp power.
  • the circuit part ADD translates the instantaneous lamp power into a voltage signal, compares this with a reference signal and outputs the difference signal to an input of the control circuit ST, which clocks the switching power supply SNT in such a way that the discharge lamp L, which is connected to the output of the switching power supply SNT, with almost constant electrical power consumption is operated.
  • a battery or an AC voltage source with a downstream rectifier can serve as the DC voltage source U Batt .
  • the inverter WR is not required for DC discharge lamps.

  • the total voltage Up or the difference signal can be used to regulate the lamp power.
