Definitions
- the present invention relates to a circuit device for operating a discharge lamp with a Konditionsgenerator- or recording device for providing an AC voltage and a Zündnapsser Wegungs Surprise, which is connected to the AC voltage generator or -issue worn and at the output of the discharge lamp is connected, for generating an ignition voltage from the AC voltage. Moreover, the present invention relates to a corresponding method for operating a discharge lamp.
- a high voltage For the operation of a gas discharge lamp, a high voltage must first be applied to the lamp to ignite the discharge process of the gas in the lamp. Subsequently, a continuous operating voltage is applied to the electrodes of the lamp.
- an electrical supply unit or circuit device can be used, which can accomplish both the ignition and the operating state or two separate power sources, one of which is used for the ignition and the other for the operation.
- a voltage source that can be used for both states must be able to generate the high voltage for the ignition and then be able to work permanently with high efficiency during operation.
- the operating frequency for the continuous operation of the lamp is limited by the inductance upwards. This is a significant limitation, especially in high-pressure lamps, which can only be operated in certain frequency windows due to the acoustic resonances that occur.
- superposition ignitors are relatively expensive due to the necessary winding quality, switching elements (eg spark gaps) and capacitors.
- the object of the present invention is therefore to propose a circuit device and a method which enable cost-effective operation of a discharge lamp with high ignition voltage.
- this object is achieved by a circuit device for operating a discharge lamp with a Konditionsgenerator- or recording device for providing an AC voltage and a Zündnapsser Wegungs adopted connected to the AC voltage generator or recording device and at the output of the discharge lamp is connected, for generating an ignition voltage the AC voltage, wherein the ignition voltage generating means comprises at least one diode which is connected in parallel to the output of the ignition voltage generating means.
- a turn-off unit for shutting off the pumping of the voltage after the ignition is used in series with the diode.
- This switch-off unit can be realized cost-effectively by a Zener diode or TVS diode (transient voltage suppressor).
- the rated voltage of this Zener diode or TVS diode should be greater than the burning voltage of the discharge lamp, so as not to hinder or even prevent the burning process.
- the above object is achieved by a method for operating a discharge lamp by providing an alternating voltage and generating an ignition voltage from the alternating voltage, wherein the ignition voltage is generated by means of a diode which is arranged parallel to the discharge lamp.
- a turn-off unit for shutting off the pumping of the voltage after the ignition is used in series with the diode.
- the diode connected in parallel with the output of the ignition voltage generating device or the discharge lamp in conjunction with the output capacitance of the AC voltage generator serves to increase the voltage amplitude in accordance with the effect of a pump circuit.
- the described circuit would correspond to a zero-order pump circuit.
- the ignition voltage generating means therefore comprises a first or higher order cascade circuit in series with the diode as the voltage pumping circuit.
- cascade circuits of this type depending on the level of their order, correspondingly high voltage peaks can be achieved, which is ultimately limited by the quality of the components used or their intrinsic losses and the time constant increasing with increasing order.
- a choke coil for current limiting.
- the ignition voltage generating device comprises a piezotransformer.
- a conventional alternating voltage source for example half-bridge, with a coupling capacitor for generating the supply voltage.
- the circuit topology according to the invention thus enables a cost-effective operation of discharge lamps with high ignition voltage, such as in high-pressure discharge lamps for automobile headlights.
- FIG. 1 shows a schematic diagram of a circuit device.
- a transformer 2 To the output of an AC power supply circuit 1, a transformer 2 is connected. The output terminals of the transformer 2 are connected to the electrodes of a gas discharge lamp 4. Between the electrodes of the gas discharge lamp, a diode 3 is connected.
- the operation of the circuit according to FIG. 1 can the in FIG. 6 shown voltage waveform are taken.
- the alternating voltage at the electrodes of the gas discharge lamp without the diode 3 has the sinusoidal voltage profile in the region A of FIG. 6 .
- the diode 3 connected in parallel with the electrodes of the gas discharge lamp 3 causes the AC voltage to be raised / lowered to positive or negative values, thus resulting in a doubling of the voltage amplitude.
- this double voltage amplitude suffices for ignition.
- FIGS. 2 and 3 Embodiments of the present invention are illustrated.
- the same switching elements or components 1 to 4 are used.
- the invention is in the circuit of FIG. 2 connected in series with the diode 3, a shutdown unit or a threshold value switch 5.
- this is a Zener diode.
- a unidirectional TVS diode can also be used.
- the Zener diode is connected as a threshold value switch 5 in the opposite direction to the diode 3.
- the diode 5 With the diode 5, the shutdown of the pump circuit is achieved after the breakthrough of the lamp, wherein the nominal voltage of the diode, ie the zener voltage, must be at least as large as the maximum operating voltage of the lamp.
- the series connection of the zener diode as a shutdown element, the pumping function of the pump circuit zero order, consisting only of the diode 3, is switched. Pump circuits of higher order are associated with FIG. 8 shown.
- FIG. 3 shown circuit has substantially the same components as that of FIG. 2 ,
- the transformer 2 in the circuit of FIG. 3 it is an electromagnetic transformer.
- the secondary-side coil is simultaneously used as a resonance coil for the resonance mode.
- a coupling capacitor 6 is connected, which is charged by the pump circuit.
- FIG. 4 shows a concrete realization of in FIG. 2 illustrated embodiment.
- the transformer 2 is designed as a piezoelectric transformer.
- the AC voltage supplied by the AC voltage supply or the generator 1 is converted by the piezoelectric element into mechanical vibrations. These transmitted via the piezoelectric element mechanical vibrations are secondary side again converted into electrical signals.
- a corresponding resonance increase in the secondary voltage occurs.
- the generator 1 for generating the primary-side AC voltage may comprise a half-bridge.
- FIG. 5 another embodiment of the circuit according to the present invention is shown.
- the AC voltage generated by the generator 1 is applied to a series resonant circuit consisting of a resonance coil 8 and a resonance capacitor 9.
- the voltage at the resonance capacitor 9 is coupled to the lamp 4 via a coupling capacitor 10.
- Parallel to the lamp 4 is already described in connection with the preceding figures pumping circuit with the diodes 3 and 5.
- the coupling capacitor 10 to avoid electrophoresis at the electrodes of the gas discharge lamp 4 should have a sufficiently high capacity for the so-called takeover, d. h the transition from the glow discharge to the arc discharge possess. If necessary, the coupling capacitor 10, a series resonance, optionally with low quality, be pre-stored to achieve higher voltages.
- FIG. 6 in the area A, the signal waveform of the AC voltage at the output of the transformer is shown, which would be applied to the discharge lamp 4, if the diode 3 were not present.
- area B of FIG. 6 the waveform is shown, which results at the discharge lamp 4 through the diode 3. This sets a doubling of the amplitude of the voltage at the electrodes of the discharge lamp 4.
- the diode 3 can thus be considered as a zero-order pump circuit, as already mentioned.
- FIG. 7 is the course of the AC voltage after the ignition of the discharge lamp, ie during the burning phase, shown. It can be clearly seen that the amplitude of the AC voltage compared to that of FIG. 6 is reduced. The reason for this is that the discharge lamp 4 after ignition has a much lower resistance, so that the voltage is reduced to her in the burning phase. Furthermore, the FIG. 7 can be seen that the pump circuit, ie the diode 3, during the firing phase has no effect, since the waveform in the region A, ie when switched off diode 3, is identical to the waveform in area B, ie when the diode is connected 3. The reason for this the Zener diode 5, through which the pump circuit is switched off after the breakthrough of the lamp in continuous operation.
- FIG. 8 is a variant of the embodiment of FIG. 4 shown.
- the circuit of FIG. 8 around a second order pump circuit.
- a cascade circuit of diodes and capacitors is connected between the diode 3 and the Zener diode 5.
- the diodes D1 to D5 are connected in series between the diode 3 and the Zener diode 5.
- Parallel to the diodes 3 and D1 is a capacitor C1
- parallel to the diodes D1 and D2 is a capacitor C2
- the components of one stage of the cascade are represented by the regions I and II in FIG FIG. 8 characterized.
- a peak voltage ⁇ 2x (U SS -U Z ) results.
- a peak voltage ⁇ 3x (U SS -U Z ) is established.
- U SS means the peak-to-peak value of the AC voltage on the secondary side of the transformer 2 and U Z the Zener voltage.
- FIG. 9 is the voltage curve at the gas discharge lamp 4 for the embodiments according to the invention according to the FIGS. 2 to 5 shown. After switching on, the final pumping voltage sets in very quickly. After ignition, the pumping process is switched off and the voltage drops to the burning voltage, as already mentioned in connection with FIGS. 6 and 7 was explained.
- FIG. 10 reproduced voltage curve.
- the AC voltage is superimposed with a DC voltage whose value is about twice as high as compared with the zero order pump circuit. After about 4 ms, the final pump value is reached. After ignition, the pumping process is also terminated and it turns on the lamp, the burning voltage as in FIG. 9 one.
- An advantage of the described ignition circuit is that in general a much lower breakdown voltage is required than with pulse ignitors, since the voltage time area is greater here.
