Definitions

  • the invention relates to an ignition circuit according to the preamble of claim 1.
  • Such an ignition circuit is known from DE-OS 31 08 547.
  • the lamp manufacturers stipulate that the series circuit comprising the surge capacitor and the auxiliary ignition capacitor must not exceed a certain maximum capacity when the starting phase has been completed, since otherwise there is a risk of the lamp aging prematurely.
  • the invention is therefore based on the object to provide a measure in the known circuit that it allows the capacitance of the series circuit comprising the surge capacitor and the auxiliary ignition capacitor to be increased without the negative consequences for the lamp feared by the lamp manufacturers.
  • the solution according to the invention ensures that the series connection of the surge capacitor and the auxiliary ignition capacitor is interrupted by the further switch element after the lamp has been ignited because the voltage across the ignited lamp drops far below the starting voltage and thus also the voltage across the further switch element below whose response voltage drops.
  • the pulse transformer In the conventional circuit it is necessary to provide the core of the pulse transformer with an air gap in order to avoid that it is alternately saturated by the steep flanks of the lamp burning current which also occur during operation. Without this measure, ie without an air gap, the pulse transformer would produce an annoying singing noise.
  • the measure according to the invention interrupts the lamp current path through the pulse transformer winding, with the result that a pulse transformer can be used without an air gap and the disturbing singing noise does not occur.
  • a pulse transformer without an air gap is smaller than an impulse transformer with an air gap with the same impedance. The smaller dimensions of such a pulse transformer without an air gap are extremely desirable for reasons of space.
  • an inductor according to claims 4 and 5 can be inserted into the circuit.
  • the inductance avoiding current peaks can further be added to a voltage-dependent resistor working as a surge arrester for the reduction of voltage peaks according to claims 4 or 6.
  • Claim 7 is directed to a special embodiment of the transformer 4.
  • the first-mentioned switch element must have such a short switch-off time that several ignition pulses can be generated one after the other.
  • the switch-off time depends on the limit voltage of the switch element at which it becomes conductive. The higher the limit voltage, the longer the switch-off time. To date, there are no switch elements for the limit voltage required here, the switch-off time of which is sufficiently short. For this reason, two switching elements connected in series, each with half the limit voltage, are used in practice.
  • a high-pressure metal vapor discharge lamp 1 shows, in a first exemplary embodiment of the invention, a high-pressure metal vapor discharge lamp 1, a choke coil 2, a pulse transformer 4 with primary winding 8 and secondary winding 5, two switch elements 9, 11, a surge capacitor 7, an auxiliary ignition capacitor 10 with a charging resistor 6, and another Resistor 12 and a housing 3.
  • the main circuit i.e. the load circuit is formed by the series connection of line reactor 2, secondary winding 5 of the transformer 4 and the high-pressure metal vapor discharge lamp 1.
  • the series connection of surge capacitor 7 is parallel to resistor 12, switch element 11 and auxiliary ignition capacitor 10 in parallel with the charging resistor 6.
  • Parallel to the parallel connection of surge capacitor 7 and resistor 12 is the series connection of the primary winding of the pulse transformer 4 and the switch element 9. Since the supply voltage is a symmetrical AC voltage, the choke 2 can also be in the other voltage supply line, or be divided into two, so that half the choke is effective in both voltage supply lines.
  • the triple pole formed by the components 7, 12, 4, 9, 6, 10 and additionally 11 is referred to below as a superimposed ignition voltage device.
  • the metal vapor high-pressure discharge lamp 1 receives its supply voltage via the three-pole connection located in the housing 3 and the line reactor 2 from a supply voltage connected to the connections labeled L and N / L.
  • the superimposed ignition voltage device is equally suitable for the ignition of metal halide and high pressure sodium discharge lamps of small and large output suitable.
  • the supply voltage supply via the connections labeled L and N / L is preferably from the 220V, 50Hz household network, but other voltage levels, e.g. 380V, 50Hz possible.
  • the switch elements 9 and 11 can be formed by Sidacs, Tridacs, appropriately connected triacs, four-layer diodes or the like.
  • the switch element 9 or 11 is normally non-conductive, but becomes low-resistance, i.e. when the voltage across it exceeds a certain limit voltage value. it guides. This applies to both polarity directions.
  • Superposition ignition voltage devices formed from three- or four-pole should, during the start phase of the high-pressure metal vapor discharge lamp 1, influence the voltage applied to it for the purpose of ignition, while during operation, i.e. after the lamp 1 has been ignited, should no longer have any further influence on the voltage form applied to the lamp 1.
  • the superimposed ignition voltage device consequently has only one two-pole, i.e. it only has the secondary winding 5 of the pulse transformer 4 in series with the choke coil 2.
  • FIG. 2 Another exemplary embodiment of the invention is shown in FIG. 2.
  • the potential-separating ignition transmitter 4 is replaced by a pulse transformer in an economy circuit.
  • the winding applied to the transformer core is divided into two, so that a primary winding 8 and a secondary winding 5 not electrically isolated therefrom are formed.
  • the common first connection of the two windings 8 and 5 is connected to an input terminal D of the superimposed ignition voltage device connected to the inductor 2.
  • the second connection of the primary winding 8 is connected to the switch element 9 and the second connection of the secondary winding 5 is connected to the one connection of the lamp 1.
  • the ratio of the number of windings of secondary winding and primary winding determines the voltage applied to lamp 1 during the ignition process.
  • the common connection of the autotransformer 4 can also be one of a plurality of winding taps, with which an adaptation of the level of the voltage present at the output connection L A of the superimposed ignition voltage device to different high-pressure discharge lamps is possible.
  • circuitry of the autotransformer 4 Apart from the circuitry of the autotransformer 4, the circuitry of the components used according to FIG. 2 is identical to that of FIG. 1.
  • the switch element 11 Since the switch element 11 becomes conductive at the moment of switching on and thus a strong current surge charges the capacitors 7 and 10, the switch element 11 can be destroyed. To limit this inrush current, among other things, the inductance 13 provided in FIGS. 3 and 4 is in the series circuit comprising the switch element 11 and auxiliary ignition probes sator 10 and surge capacitor 7 inserted.
  • the insertion of the inductance 13 between the switch element 11 and the one common connection of the parallel circuit comprising the surge capacitor 7 and the resistor 12 has the advantage that the inductance simultaneously limits the current in the primary ignition circuit, consisting of the series connection of the primary winding 8, the switch element (s) 9 and the surge capacitor 7.
  • a voltage limiting element 14 connected in parallel to the switch element 11 is added.
  • This voltage limiting element 15 protects the switch element 11 from possible, e.g. Overvoltage generated by inductor 13.
  • the voltage limiting element 14 can be formed from surge arresters (TAZ diode) or from antiserially connected tens diodes. It is able to absorb short-term pulsed energies so that they are not supplied to the switch element 11.
  • the substantially ohmic parallel branch that arises via the resistor 12, the inductor 13, the surge arrester 14 and the charging resistor 6 means that the superimposed ignition voltage device is no longer a pure two-pole connection in the operating state of the lamp 1, but this parallel branch is high-impedance and thus in the operating state of Lamp 1 of minor importance.
