Definitions

  • the invention relates to a circuit arrangement for igniting a high-pressure gas discharge lamp, which is connected on the input side to a magnetic ballast for providing an AC supply to the lamp, according to the preamble of claim 1 and a method for operating a high pressure gas discharge lamp with an ignition circuit.
  • the latter Due to the high electrical and thermal load, in particular at the electrodes of the high-pressure gas discharge lamp, the latter have a limited life, which leads to malfunction at the end of use. Typical is, for example, a so-called cycling operation in which the lamps extinguish after a short burning time, are restarted by the ignition circuit, etc. Furthermore, there is the problem that due to the aging process in particular at the electrodes of the lamp high power losses are generated, which ultimately can lead to a short circuit or even to a bursting of the glass vessel of the lamp. Such effects can also lead to the fact that the ballast is damaged by the heat and must be replaced together with the defective lamp.
  • thermal switch in the supply circuit of the lamp, which interrupts the AC supply to the lamp when heat buildup occurs when the associated temperature sensor detects exceeding a predetermined temperature.
  • a thermal switch can be designed, for example, as a fuse, which responds after the occurrence of an elevated temperature in the vicinity of the ballast or the high-pressure gas discharge lamp.
  • the use of such a thermal switch is relatively uncertain, since such a temperature sensor can detect the fault in the lamp only delayed in time, because the heat loss must be transferred via heat conduction only from the place of origin of electrical power loss to the sensor.
  • the object of the invention is to at least partially avoid the described disadvantages of circuit arrangements of the prior art.
  • a circuit arrangement for igniting a high-pressure gas discharge lamp which is connected on the input side to a magnetic ballast for providing an AC supply to the lamp, with the features of claim 1.
  • the circuit arrangement according to the invention on an ignition transformer, which may be formed for example as a pulse transformer, which is connected on the primary side with a Zündauslösesciens and secondary side between the ballast and the lamp for transmitting an ignition pulse is arranged on the lamp.
  • the circuit arrangement further comprises a surge capacitor and a first switch element, wherein in the Zündauslöseschari a series circuit, comprising at least the first switch element and a primary winding of the Zündübertragers the shock capacitor is connected in parallel.
  • the circuit arrangement according to the invention is characterized in that a series connection, which has at least one controllable second switch means, the lamp for extinguishing the same is connected in parallel and a means for detecting the degree of asymmetry of the lamp voltage is provided and a control device for extinguishing the lamp by the Driving the second switch means in response to the detected unbalance of the lamp operating voltage.
  • the circuit arrangement according to the invention is designed to determine the degree of asymmetry of the lamp operating voltage, the Aging condition of the gas discharge lamp can be determined before malfunction or damage to the ballast or the circuit arrangement occur.
  • This effect is due to the fact that such aging of a high-pressure gas discharge lamp as a rule is due to an asymmetry of the cathode drop voltage at the two electrodes, which in turn is caused by a difference in the work function of the electrons at the two electrodes.
  • the controllable second switch means can short the lamp and thus erase it, thereby preventing the degree of unbalance of the lamp operating voltage from being further increased. In this way, the emergence of a dangerous power loss during operation of the lamp is avoided, since otherwise caused by the asymmetry of the cathode drop voltage at the electrodes despite the AC power rectification effect in the lamp, in which the magnetic ballast, in particular a choke, has no current-limiting effect.
  • the controllable by the controller for shorting the lamp second switch means is part of a series circuit, which is connected in parallel to the lamp and at least this switch means and the connections to the lamp.
  • the circuit arrangement according to the invention is accordingly able to terminate the operation of the high-pressure gas discharge lamp early enough before other components can be damaged during further operation of the lamp or other malfunctions can occur. In general, then it is sufficient to replace the aged high-pressure gas discharge lamp to operate the relevant lighting device again.
  • control device of the circuit arrangement has a timer circuit for controlling the ignition operation of the circuit arrangement, in particular with a counting device for detecting the number of lamp ignitions and / or a counting device for detecting the past ignition time for a detonation attempt.
  • the total ignition time of a Zünd baths can be detected and compared with a stored value. If this predetermined value is exceeded, it is possible to conclude that the lamp has malfunctioned and, to that extent, to prevent further ignition attempts. The same applies to the exceeding of a predetermined number of lamp ignitions within the ignition operation of the circuit arrangement.
  • controllable, third switch for switching off and / or blocking the Zündauslösesclien, which is connected in parallel, for example, the surge capacitor and insofar short-circuits if necessary.
  • a series circuit which has at least one capacitor and one resistor, wherein this series connection of the lamp is connected in parallel.
  • the magnetic ballast is designed as a conventional throttle.
  • the series circuit comprising the second switch means does not comprise this throttle, so that the choke is not loaded by the short circuit caused by the second switch means for extinguishing the lamp.
  • the method the above object is achieved by a method for operating a high-pressure gas discharge lamp, which is connected to a magnetic ballast for providing an AC supply voltage, with an ignition circuit, which is switched off after the ignition of the lamp.
  • the inventive method is characterized in that during operation of the lamp, the degree of asymmetry of the lamp operating voltage is detected and this degree is compared with a predetermined value and when exceeding the predetermined value, the lamp is shorted to extinguish the lamp discharge.
  • This time interval may, for example, comprise a few milliseconds sufficient to extinguish the high pressure gas discharge lamp. Thereafter, the short circuit can be canceled again, as far as it is ensured that the lamp is not ignited or subsequent ignition attempts are allowed.
  • the blockage of the ignition circuit is preferably removed after it is disconnected from the power supply and subsequently reconnected to this.
  • the detection of the degree of asymmetry of the lamp voltage during operation of the lamp can also be used to determine the time course of this asymmetry, whereby ultimately a prognosis for the remaining operating time of the lamp can be determined.
  • the time duration is determined, which remains until the lamp reaches a predetermined limit of the unbalance of the lamp operating voltage at which the lamp is turned off according to the invention.
  • This determined period of time can be optically displayed or digitally or analogue output at a corresponding port for further processing or display.
  • the detected measure of the unbalance of the lamp operating voltage during operation may be used to establish an allowable number of ignition attempts. After expiration of this determined in dependence on the detected degree of asymmetry of the lamp operating voltage number of ignition attempts can then the ignition circuit be blocked.
  • the determined degree of asymmetry of the lamp operating voltage is used for determining the permitted ignition time within which ignition attempts may be carried out.
  • the permitted number of ignition attempts or the permitted ignition time can be calculated in proportion to the distance of the detected asymmetry from the permitted asymmetry of the lamp operating voltage. In this case, this allowed unbalance of the lamp operating voltage just corresponds to the degree just before the lamp is extinguished.
