Definitions
- the invention relates to a method for switching off a circuit arrangement for the operation of a discharge lamp according to the preamble of the claim 1.
- German patent applications DE-A-36 23 749 and DE-A-36 11 611 are circuit arrangements without a shutdown device for the operation of Fluorescent lamps proposed.
- a disadvantage of these circuits is that in the event of a faulty operating state of the lamp, the circuit arrangement is not deactivated. Because of the way the active Harmonic filter, through the ongoing energy in the smoothing capacitor is pumped back, it can therefore be destroyed if the lamp fails of the smoothing capacitor.
- a switch-off device is known from DE-A-29 41 822, as listed in the preamble of the first claim.
- This shutdown device includes a trigger circuit with a precisely dimensioned Diac, the thyristor with a delay of about a second switches off.
- a delay time of up to one second is however for a circuit arrangement with a designed as a pump system Harmonic filter too long since it becomes a strong one in far shorter times Voltage rise at the smoothing capacitor can come.
- From EP-B-276 460 is a circuit arrangement for high frequency Operation of a low-pressure discharge lamp is known, which has a shutdown device has, which is capable of a thyristor of the shutdown device switch through within a few milliseconds and thus switch off the circuit arrangement causes. If there is a failure of the low-pressure discharge lamp through capacitors of an active harmonic filter causes a voltage rise across a smoothing capacitor. If the voltage rise exceeds the breakdown voltage of one or several Zener diodes of a trigger circuit connected in series these diodes and thus trigger the turn-off thyristor directly.
- This Circuit arrangement enables the shutdown in the event of failure of a low-pressure discharge lamp; however, it is unable to do the so-called "End-of-live” state (e.g. one-sided emitter depletion on one electrode) to be recorded and corresponding switching measures to be recorded. Furthermore this circuit arrangement is not able to create a symmetrical one or an asymmetrical increase in lamp voltage in time and with to detect sufficient accuracy.
- End-of-live e.g. one-sided emitter depletion on one electrode
- the object of the invention based on a method for switching off a circuit arrangement of the Specify the type mentioned above, the shutdown in different Failures of gas discharge lamps enabled.
- the discharge lamp is continuously checked for faulty conditions, whereby uses the peak-to-peak voltage as a criterion becomes.
- One of these defective conditions is the so-called Rectifier effect against or at the end of life (different lamp voltage amplitudes regarding the two voltage half-waves; a asymmetrical lamp voltage increase) and a symmetrical lamp voltage increase, for example by "microleak" (drawing air in the inside of the lamp body).
- the peak-to-peak voltage is used as a parameter for the detection different fault conditions used.
- a lamp voltage detection device a control signal is formed that corresponds to the peak-to-peak voltage represents proportional voltage. You can't do that only the peak-to-peak voltage itself, but also derived from this voltage Use physical parameters.
- EPC In EP-A-696 157, which was published on 07/02/1996 and therefore represents prior art under Art 54 (3) EPC, is an electronic ballast for gas discharge lamps described with a shutdown arrangement that the ballast at switches off symmetrical and asymmetrical overvoltages.
- the Ballast however, has two different detection circuits for this purpose on.
- EP-A-564 895 describes an electronic ballast for low-pressure gas discharge lamps with a shutdown arrangement consisting of a voltage multiplication circuit. Here is, however no switching off of the ballast with an asymmetrical increase the voltage on the lamp as a result of the "end-of-live" state.
- Low frequency means a frequency corresponding to the order of magnitude of the network frequency, while high frequency denotes a frequency above one Low frequency.
- the circuit arrangement On the input side, the circuit arrangement has a generator G, which e.g. generates a high frequency voltage. Generally the generator generates an alternating voltage for operating the discharge lamp.
- the generator G is on the input side with the mains voltage or with an in Power supply part not shown in Figure 1, e.g. a line rectifier, connected.
- the discharge lamp LP can, for example, have a preheating device VH be connected.
- the generator G has to generate an alternating frequency voltage a control input with a generator shutdown device AV connected is.
- This shutdown device AV generates depending on one Input signal (second control signal) CS2 a first control signal CS1.
- the first control signal CS1 activates the generator G in such a way that the generation the alternating frequency voltage is ended.
- a voltage detection device VE is provided, on the one hand connected to the electrodes of the discharge lamp and the voltage U ss to the discharge lamp LP taps in the example shown in Figure 1 example.
- the voltage detecting device PU forms in dependence of the detected lamp voltage U ss a second control signal CS2.
- This second control signal CS2 is supplied to the generator shutdown device AV.
- This second control signal CS2 which is supplied to the generator shutdown device AV, activates this shutdown device AV in such a way that the shutdown device forms the first control signal CS1 and thus prevents the generation of the alternating-frequency lamp voltage.
- the voltage detection device VE can also provide a second control signal Form CS2 by a voltage proportional to the peak-to-peak voltage UA is formed.
- the shutdown device AV can in the way be designed so that it forms the first control signal CS1, provided that the peak-to-peak voltage proportional voltage UA a predeterminable Threshold exceeded.
- the voltage detection device VE shown in FIG. 2 becomes, for example by a voltage multiplication circuit known per se educated. According to the invention, this voltage multiplication circuit used to detect different faulty conditions of the discharge lamp.
- This circuit arrangement has on the input side in its side facing the lamp LP a voltage divider R1, R2 to which the peak-to-peak voltage U ss is applied.
- a first capacitor C1 is arranged on the voltage divider the center tap of the voltage divider facing away from both Anode of a first diode D1 as well as the cathode of a second diode D2 is connected.
- the anode of the second diode D2 is connected to ground.
- the cathode of the first diode D1 is with an output of the voltage detection device VE connected.
- a second capacitor C2 is connected to the first diode D1.
- the first capacitor C1 In the negative half wave of the voltage U m , the first capacitor C1 is charged via the second diode D2 in accordance with the maximum negative voltage of the lamp LP. In the positive half cycle of the voltage Um, the first capacitor C1 is discharged onto the second capacitor C2 via the first diode D1.
- the voltages U m and the voltage U C1 formed in the negative half-wave of the voltage U across the capacitor C1 add m.
- the voltage thus formed corresponds to the peak-to-peak voltage U ss.
- the voltage U m at the center tap of the voltage divider against ground represents a proportional part of the voltage U ss .
- the diode D1 and the capacitor C2 serve to store the detected peak-peak voltage U ss .
- the peak-peak voltage U ss or U m is formed when the generator cut-off device AV connected in parallel with the capacitor C2 has an infinite impedance (VE not loaded by AV; idle case).
- the signal formed in the manner described above can be measured with additional can be combined in particular with the operating voltage, since in the case of the invention Switching the signal proportional to the peak-peak voltage is generated against the reference ground of the generator circuit.
- the first diode D1 can be replaced by a Zener diode.
- the second diode D2 can also be replaced by a Zener diode.
- the voltage detection device VE formed voltage are compared with a threshold value.
- the Threshold for shutdown in case of overvoltage can be independent of the response time of the shutdown the ignition can be set (voltage divider R1, R2 and capacitor C2).
- Zener diodes for D1 and / or D2 instead of normal Diodes enables the use of a smaller capacitor C2 with the same Response time in the ignition process.
- the circuit arrangement according to FIG. 2 is very general built with relatively few standard circuit components, the total represent a very inexpensive solution. Because of this circuit structure with only a few components it is also guaranteed that this circuit has high operational reliability.
