Definitions

  • the present invention relates to an electronic ballast for discharge lamps, specifically for such discharge lamps having preheatable electrodes.
  • Electronic ballasts for the operation of discharge lamps are known per se.
  • an electronic ballast from a given supply for example a mains supply, generates a supply power for a connected discharge lamp, which has the characteristics necessary for the operation of the discharge lamp, in particular a high-frequency AC voltage supply.
  • the electrodes of a discharge lamp are preheated prior to the ignition of the discharge. In this way, the emissivity of the electrodes can be improved and extend their life.
  • a preheat process typically lasts between 0.4 s and just over 2 s and occurs after a preheat program set in a scheduler.
  • WO 02/19778 A2 (Giannopoulos ) describes a combination of a gas discharge lamp and an electronic control gear.
  • the lamp is equipped with impedance elements on its electrodes by means of which the operating device detects the lamp type.
  • the invention is based on the problem of specifying an improved ballast for discharge lamps with preheatable electrodes.
  • the invention relates to an electronic ballast for operating a discharge lamp according to claim 1.
  • the invention is based on the recognition that simply carrying out a predetermined preheating process can lead to an unsatisfactory result of the preheating process. Even if an electronic ballast is designed and used to operate discharge lamps of the same type in each case; For example, the preheating process may be slightly different for each discharge lamp. A different from lamp to lamp course of preheating can be due to manufacturing tolerances of the preheatable electrodes and tolerances of the components of the electronic ballast.
  • the preheatable electrodes of a discharge lamp after the preheating time could not reach the desired temperature, while in extreme cases, the preheating leads across the electrodes of another discharge lamp to ignite an unwanted transverse discharge.
  • the aim is a shortest possible preheating, i. It should be used as large as possible Vorchingströme or Voriffenciesen without a voltage across the electrodes, which leads to a transverse discharge.
  • the electronic ballast according to the invention has a measuring device which is designed, during the preheating process, the temperature of at least one electrode of at least one connected Discharge lamp to measure. For the measurement of the electrode temperature, any correlated property can be measured. Suitable quantities are dealt with within the scope of the dependent claims.
  • a control device compares the measured values of the measuring device with standard values of the value correlated to the electrode temperature. In the event of a deviation between the measured and standard values, the control device adapts the following course of the preheating process by changing an operating parameter of the electronic ballast so that the expected deviation between a subsequent measurement and a corresponding standard value becomes smaller. This process is therefore in principle a regulation.
  • a variable correlated to the electrode temperature is measured only once, preferably in the middle region of the expected preheat interval. In response to this measurement, if necessary, an intervention of the control device follows.
  • Examples of operating parameters of the electronic ballast which are suitable for adjusting the course of the electrode temperature during the preheating, are: the Vortexstrom through the electrodes, the preheating voltage at the electrodes, the frequency of the high frequency AC power supply generated by the electronic ballast and the duty cycle just this AC power supply.
  • the default values of the value correlated to the electrode temperature can be stored in a memory device within the electronic ballast, or else hardwired in the form of an electronic circuit, for example a circuit, which has threshold elements (comparators) to which the measured values are supplied and whose threshold values decide on this whether there is a deviation from the standard values.
  • a circuit which has threshold elements (comparators) to which the measured values are supplied and whose threshold values decide on this whether there is a deviation from the standard values.
  • Such a circuit could simultaneously implement the control device as well.
  • an electronic ballast according to the invention can also have increased flexibility when using different lamp types. Although different types of lamps may have different electrodes, the control circuit can be used to effect an efficient preheating process.
  • the measuring device is designed to measure the electrode resistance as the quantity correlated to the electrode temperature.
  • the electrodes represent an ohmic resistor with a positive temperature coefficient.
  • the electrode resistance during the preheating time results from the preheating voltage and the preheating current, so it is easy to determine.
  • the measuring device is designed to measure the cold resistance of one of the electrodes of a connected discharge lamp after switching on the electronic ballast and before or at the beginning of the preheating process.
  • the cold resistance of an electrode is understood here as meaning the resistance of an electrode when its temperature corresponds to the ambient temperature.
  • the electrode resistance during the preheating time is measured by the measuring device. The quotient of the current electrode resistance, ie the heat resistance, and the cold resistance, is just like the electrode resistance itself, approximately proportional to the temperature of the electrodes. Since it is divided by the cold resistance, but a normalized in this regard size is used.
  • control device may be designed to carry out the determination of the quotient of the cold resistance measured by the measuring device and the heat resistance likewise measured by the measuring device.
  • the quotient of the actual resistance of one of the electrodes and the cold resistance is not only interesting for adaptation to a standard course of the preheating process, but also to detect extraordinary processes by means of the measuring device, which can be reacted accordingly by means of the control device.
  • the course of the electrode temperature must in any case correspond to the standard values. Deviations are possible, especially with a few measured values. For example, the electrode temperature may reach a sufficient level earlier than expected.
  • ignition should then be initiated, for example via the control circuit.
  • the discharge is ignited. More preferred is a lower limit for the ignition of the discharge of 4.5 and independently an upper limit of 6.
  • a transverse discharge may occur. Querentladungen are not desirable, inter alia, because with a transverse discharge, the electrode temperature decreases again. at If the temperature is lower, the electrode will be less emissive and igniting the discharge if the temperature is too low will increase the wear. Transverse discharges can be detected on a non-monotonic course of a variable correlated to the electrode temperature. If a transverse discharge is detected, a preferred embodiment of the invention is designed to initiate ignition.
  • a decrease in temperature across an electrode can be detected by a nonmonotonic history of a value correlated to electrode temperature within the preheat time. For example, with a transverse discharge across the electrode, your resistance and the voltage drop across it also decrease. However, the current through the electrode increases due to the lower resistance. How strongly these behaviors are pronounced also depends on whether the heating power supply has more of a voltage source characteristic or a current source characteristic. Really, the properties of the heating power supply will be between these extremes.
  • the quantity correlated to the electrode temperature, which is used for cross-discharge detection is the voltage across one of the electrodes
  • the electronic ballast has a pronounced current source characteristic, then it makes sense to observe the voltage across one of the electrodes for transverse discharge detection. If the electronic ballast is a pronounced voltage source, a transverse discharge detection via the quotient of hot and cold resistance, which is determined by means of a current measurement, is recommended.
  • this size is preferably measured by the measuring device at least every 100 ms. In the usual preheat times Thus several measurements are possible during the preheating process.
  • the electronic ballast can be operated not only with one, but with several different types of lamps, it can be used advantageously a lamp type detection.
  • the lamp type is determined by measuring the cold resistance of an electrode of a connected discharge lamp.
  • the storage device is designed to store a set of suitable preheating parameters for different lamp types, for example the preheating time, standard values for the heating current and the heating voltage and the maximum permitted heating voltage. If the electronic ballast has detected the connected lamp type on the basis of the cold resistance, then the control device controls the preheating process in accordance with the standard values corresponding to the lamp type.
  • the electronic ballast may be provided with a timer to determine if the power interruption was shorter than a predetermined duration. If this is the case, then no measurement of the cold resistance is carried out after the power interruption, otherwise already.
  • the invention also relates to a method for operating a discharge lamp equipped with preheatable electrodes, comprising the steps of: connecting the discharge lamp, measuring at least one of the variables correlated to the electrode temperature increased by the preheating the electrodes during the preheating with a measuring device, adjusting the electrode temperature during the preheating by adjusting an operating parameter of the electronic ballast by means of a responsive to the measurement control device, and also relates to the above and implicitly also explained for this method embodiments.
  • FIG. 1 shows a circuit diagram of an electronic ballast according to the invention.
  • the electronic ballast is fed from the mains supply lines N1 and N2.
  • a generator G generates from the given mains supply N1, N2 a supply power for a connected low-pressure discharge lamp LA.
  • the generator G includes a rectifier for rectifying the AC power supply, a power factor correction circuit for a possible sinusoidal current drain from the mains supply, a DC link capacitor and a half-bridge inverter, which rests on the DC link capacitor to supply the Halbmaschineninverters necessary DC voltage.
  • the half-bridge inverter generates a high-frequency alternating voltage between the output A1 and the reference potential GND or the other potential of the intermediate circuit voltage.
  • a series circuit of a lamp inductor L, a coupling capacitor CC, a lamp terminal KL1A, the low-pressure discharge lamp LA, a lamp terminal KL2A and a resistor R1 is connected.
  • a series circuit of a lamp terminal KL1 B, a resonance capacitor CR and a lamp terminal KL2B is connected.
  • the electrode E1 and between the lamp terminals KL2A and KL2B is the electrode E2.
  • connection node K1 Between the lamp terminal KL2A and the resistor R1 is a connection node K1. Between a second output at the generator A2 and the connection node K1, a control device C and a measuring device M is connected.
  • the control device C and the measuring device M are part of a microcontroller, and are therefore drawn with a common enclosure. Both the control device C and the measuring device M have a reference to the reference potential GND.
  • the control device C can via a control line SL operating parameters of the generator Set G, here the heating current.
  • the measuring device is connected via the node K1 in series with the reference potential GND. Furthermore, the measuring device M is connected in series with the resonance capacitor CR via the lamp terminal KL2B. Between the resonant capacitor CR and the measuring device M is a connection node K2. At this connection node, the lamp terminal KL2B is connected.
  • the voltage dropped across the resistor R1 is proportional to the current flowing through the electrode E2 between the lamp terminals KL2A and KL2B.
  • the voltage across the resistor R1 can be detected by the measuring device M.
  • the voltage between the lamp terminals KL2A and KL2B can also be detected by the measuring device M.
  • FIG. 2 shows a typical course of a correlated to the electrode temperature of the low-pressure discharge lamp LA size during the preheating process.
  • the measuring device M measures, here 10 times, the resistance RW of the electrode E2 between the lamp terminals KL2A and KL2B during the preheating time.
  • the preheating process starts at time t0 and ends at time t1.
  • the resistance RW of the electrode also increases and reaches its highest value until the end of t1 of the preheating time, here after 0.5 s.
  • the electrode resistance Before the preheating process has led to a significant heating, the electrode resistance has the value RK, its cold resistance.
  • the value correlated to the electrode temperature is the quotient of RW and RK as a function of time, which reaches the value 5 at the end t1 of the preheating time, which corresponds to an electrode temperature of almost 800 ° C.
  • FIG. 3a shows a time course of the quotient of hot and cold resistance and FIG. 3b shows the associated heating current IE2, the heating current through electrode 2, which is adjusted during the preheating process.
  • the control device C five different default values for the quotient appear during the preheating process for different lamp types from the hot and cold resistance and the heating current stored.
  • the measuring device M determines the cold resistance of the electrode E2. Based on the cold resistance RK of the electrode E2, the lamp type is detected and the standard values corresponding to the detected lamp type are selected as a comparison scale for the control device C for the preheating process.
  • the crosses in the FIGS. 3a and 3b each correspond to the default values stored in the control device.
  • FIG. 3a corresponds to the actual course of the quotient of hot and cold resistance and the solid line in FIG. 3b corresponds to the actual course of the heating current during the preheating time.
  • the controller adapts and increases the heating current so that the quotient of hot and cold resistance has a greater slope.
  • the heating current change is here proportional to the difference between the measured quotient of the hot and cold resistance and the associated standard value.
  • FIG. 4 shows the quotient of RW and RK as a function of time during the preheat process for two different preheat operations.
  • the preheating process is completed at time t1.
  • the quotient reaches the value 5 before the expected end t1 of the preheating time. However, when the quotient reaches 5, the electrode is hot enough and the discharge is ignited.
  • the initially increased temperature of the electrode drops again. This is in FIG. 5 is shown and also expressed in that the quotient of the current electrode resistance RW and the cold resistance RK decreases.
  • the measuring device M takes here in the interval between t0 and t1 ten measurements of the electrode resistance RW before. If the electrode resistance falls within this interval after it has risen first, this is an indication of a transverse discharge; the discharge is ignited.
