Definitions

  • the return voltage of the high-pressure discharge lamp At ignition voltages up to 25 kV, the return voltage can be so high in particular directly after ignition, that they are assigned to the reflector of the Headlamps can skip. Due to the high voltages occurring results thereby the danger of Verletzunöcn for car mechanics or hobbyists, which coincidentally when the discharge lamp is switched on, the reflector is in contact. Due to the high temperatures - for example, is a typical value for the temperature of the discharge vessel 700 ° C, so that a return conductor located in the vicinity still remains heated to 550 ° C - no plastic insulation can be used.
  • a third inductance in the electrical connection between the connection for supplying an ignition voltage and the associated connection arranged for the high-pressure discharge lamp, a third inductance, with the the first and the second inductance is magnetically coupled.
  • the return conductor and the forward conductor connected via a diode branch. This one serves for safety.
  • the lamp control gear electronic ballast, electronic ballast
  • This interference current can through the third Winding be largely suppressed.
  • the mode of action is based on that this measure the impedance for the interference current is also high at port 4.
  • the output signals of the current-compensated choke 22 and the voltage applied to terminal 4 ignition voltage enter a block 24, the On the one hand an ignition circuit umtasst, on the other hand is designed so that its outputs 26 and 28, the high pressure discharge lamp 14 after ignition in operation with voltage can be supplied.
  • FIG. 5 shows some embodiments of current-compensated chokes, as used in a device according to the invention Circuit arrangement can be used, wherein the respective Cores are wrapped for clarity with 2 windings.
  • Figure 5a is a Ferrite core 46 provided with two windings, the first 30 and the second inductor 32nd the current-compensated throttle 22 form. The beginning of the winding is always A, the End marked with E. If a high-insulation ferrite is selected, wires can be used are wound, which are isolated from each other only by commercial cool insulating varnish. No additional carrier is needed, i. The wrapped ferrite core can be directly, for example in SMD technology, to be used in the circuit. This results in a clear Space saving.
  • Figure 5b shows the use of a toroidal core 48 on which the two Windings are wound.
  • Figure 5c another variant with ferrite core 46 is shown.
