Definitions

  • the present invention relates to a circuit and a method for operating a dielectrically impeded discharge lamp.
  • Dielectric barrier discharge lamps are known and draw essentially by the fact that at least a part of the for the Ignition and maintenance of discharge used electrodes is separated from the discharge medium by a dielectric layer. she are sometimes referred to as "silent discharge lamps". Such Discharge lamps are powered by electronic ballasts or more generally spoken operating circuits ignited and operated. I. d. R. are for ignition larger voltages and thus in the power input larger amplitudes necessary than in continuous operation.
  • Operating circuits for such lamps regularly include a converter for coupling the power into the lamp.
  • such discharge lamps operate with AC power of various kinds, wherein in particular a pulsed mode of operation with time-without power einklplungsbuild Times disconnected power input phases due the resulting efficiency gains are of interest.
  • the invention refers in principle but to operating circuits of any kind for dielectric disabled discharge lamps. It is known in a the converter energized line path to switch a switching transistor, the by its switching operation for the ignition process and in the case of a pulsed Continuous power input also responsible for the actual lamp operation is.
  • the used converters have i. d. R. an inductive characteristic, specifically, it is i. d. R. transformers with a primary winding, which is energized by said switching transistor with power.
  • this switching transistor in the event Protect that a startup is attempted without having a lamp properly connected.
  • an energy that, if not at least partially removed from the lamp, in the switching transistor is dissipated.
  • It can be a surge protection circuit be used, which is the voltage across this transistor, for example measures the drain-source voltage at a FET, and in the If a threshold is exceeded, the lamp operation stops.
  • the invention is based on the technical problem of an operating circuit for a dielectrically impeded discharge lamp with an inductive Converter and an overvoltage protection circuit for a switching transistor and a method of igniting such a dielectrically impeded discharge lamp to improve in such a way that they at an operational start attempt show improved properties when the lamp is missing.
  • the invention relates to an operating circuit designed to at a restart of the lamp operation, first at least one test power pulse to put on the converter, which is so small that the destruction of the switching transistor as a result of this test power pulse excluded is, and the overvoltage protection circuit on one by this Test power pulse then generates voltage at the switching transistor, if no lamp is connected, and then does not respond, when the lamp is connected.
  • the inventor has found that the described monitoring of the voltage over the switching transistor in practically relevant cases not always sufficient. This is especially the case with larger lamp powers and / or if, due to the circuit, a dissipation in the converter inductance stored energy in only one of possibly several Switching transistors takes place, so early to a destruction of the Switching transistor come that mentioned overvoltage protection circuit does not respond quickly enough.
  • the invention therefore goes the way it is before finding that actually a lamp connected properly is not, even for the switching transistor critical energies in let the transducer inductance come. Rather, in one of the lamp ignition initially referred to herein as test power pulses Power pulses are applied to the converter.
  • the inductor If the lamp is missing, so the inductor generates a larger induction voltage and generates thus in the switching transistor, a larger current or a greater power loss or a larger voltage drop across the switching transistor as if the lamp is connected and therefore an essential part the energy is removed from the inductance.
  • test power pulses can therefore depend on the individual case the anticipated destruction mechanism in terms of voltage, current moderately and / or in terms of performance of the later Zünd elaboratespulsen or Distinguish operating power pulses.
  • test power pulse is sufficient for this, preferably however, several such pulses delivered.
  • the transducer is constructed so that He works on the flyback principle, so in certain phases through Current flow through an inductance stores energy and this during blocking of the current flow to the discharge lamp emits.
  • the Switching transistor thus in the energy storage phases and locks in the Energyeinkopplungsphasen. Is not there a lack of energy input Lamp connection so the switching transistor is at risk, for example in the case of a MOSFET, by one above the allowable operating range lying avalanche breakdown (ie one operation, usually drain-source current outside the Avalanche Save Operating Area (Avalanche SOA)).
  • Avalanche SOA Avalanche Save Operating Area
  • a digital monoflop For driving the control input of the switching transistor, such as the gate, can be used advantageously a digital monoflop, so a monostable multivibrator that lasts for a certain predetermined time responsive to an input, assumes an initial state that follows This time falls back into a stable ground state. It will be on the Referenced embodiment.
  • the size of the test power pulses mentioned can be, for example, by Adjusting a reference value of a comparator affecting the Current through the switching transistor compares with this reference value. In the case the flyback converter then determines when the by the Transducer inductance and the switching transistor flowing current sufficient has reached great value to match for a test performance pulse Amount of energy in the transducer inductance to stand. Also for this is refer to the embodiment.
  • the reference value can be advantageously via a microcontroller Taxes.
  • the invention further preferably relates to such operating circuits, in which also the timing of the converter by one, and preferably the same, microcontroller is controlled.
  • the control of Converter clocking can be via the enable input of the mentioned monoflop take place, as the embodiment shows.
  • the mentioned and principally known overvoltage protection circuit is preferably with a peak rectifier, such as a voltage divider circuit, a diode and a capacitor, and a low-pass characteristic, about as a result of having the capacitance of the capacitor cooperating ohmic impedance built.
  • a peak rectifier such as a voltage divider circuit, a diode and a capacitor
  • a low-pass characteristic about as a result of having the capacitance of the capacitor cooperating ohmic impedance built.
  • the invention is also directed to a set of an operating circuit as described above and a suitable one and preferably already connected dielectrically impeded discharge lamp built-up lighting system.
  • This lighting system but is also in the not yet connected state, that is about in separate and packaged manner, already the subject of the invention.
  • the invention is also preferably directed to the case of a so-called.
  • Flat radiator design the discharge lamp, which consists of a flat flat discharge vessel exists and often, but not exclusively, for backlighting is used by monitors.
  • the monitor is also aimed at this monitor Invention, wherein the term "monitor” hereby both computer monitors as well TV screens as well as display panels of other types.
  • the invention is particularly in large flat radiators and Monitors, for example with a format over 20 "diagonal.
  • DBD denotes a dielectrically impeded discharge lamp, which is connected in a secondary circuit with a secondary winding L s of a transformer.
  • the transformer has a primary winding Lp which is supplied by a voltage source U zk , the intermediate circuit voltage of an otherwise known and conventional converter. This generates a current flow represented by the arrow and the symbol Ip through the primary winding Lp, which then flows through a lying in series with the primary winding Lp MOSFET T and a shunt resistor R 1 to ground.
  • the left-hand gate input of the MOSFET switching transistor T is driven by a monoflop M with an input x and an output y and an enable input e.
  • the input x of the monoflop M is in turn driven by a comparator K, at the positive input of a reference voltage U 0 to ground and at its negative input, the voltage between the source terminal of the switching transistor T and the shunt resistor R 1 is applied to ground.
  • the tapped off between the primary winding Lp and the switching transistor T voltage to ground is divided down via a voltage divider circuit R 2 , R 3 and placed via a diode D to a connected to its other side to ground capacitor C.
  • To the capacitor C is a resistor R 4 in parallel.
  • the functioning of the circuit is essentially as follows: When the switching transistor T is conductive, current flows through the primary winding Lp and charges it inductively. If the switching transistor T is blocked, a sudden induction voltage is produced at the primary winding Lp and at the secondary winding L s , which means a power injection pulse for the dielectrically impeded discharge lamp DBD. On the other hand, the induction voltages at the secondary winding L s during the charging phase are below the threshold necessary for a discharge in the lamp DBD.
  • the gate input of the switching transistor T is driven by the monoflop M, which operates essentially as summarized in FIG.
  • the monoflop M In response to a falling in Fig. 2 above wherein x drawn edge of the input signal changes the output y of the monostable multivibrator M from the high level to the low level and remains at this low level for a certain fixed period of time t from Thereafter, the one-shot falls into the stable Zusand back with high output level.
  • This process responds only to the falling edge at the input x and is, as indicated in Fig. 2 above by two different waveforms of the input signal x, completely independent of whether the input signal before or after the end of the time t off again with a rising edge returns to the high level.
  • the monoflop M defines the length of the power injection phases of the transformer L p / L s . These power injection phases are triggered via input x. Furthermore, the output of the monoflop M is always low when the enable input e is low. The enable input e releases the monoflop M with a high level state for the described mode of operation.
  • the intermediate circuit voltage U zk with the primary circuit current I p charges the primary winding L p of the transformer L p / L s through the switching transistor T and the shunt resistor R 1 until the voltage across the shunt resistor R 1 drops towards Mass reaches the value U 0 and thus generates a sign change of the output of the comparator K.
  • the monostable multivibrator M is triggered and locks the switching transistor T for the time t, so that a soupeinkopplungsphase begins.
  • the microcontroller which picks up the voltage across the resistor R 4 to ground, suspend further operation and possibly also output a warning signal.
  • the microcontroller sets the reference value U 0 clearly high. This generates much larger power pulses, which in a manner known per se lead in a pulsed manner to the ignition of the lamp DBD. After ignition or after a specified ignition phase, the reference value U 0 can be lowered again by the microcontroller to maintain the continuous operation of the lamp DBD with a reference value U 0 , which is greater than the initial, but smaller than the value used during the ignition phase , Of course, the microcontroller may also affect the length of time t out of the monoflop by an internal voltage threshold in the monoflop.
  • Figs. 3 and 4 illustrate this in time charts, wherein Fig. 3 shows the prior art.
  • the time axis is designated t in both cases.
  • the enable signal e is plotted vertically and in the lower area vertically the reference value U 0 .
  • the reference value U 0 is lowered in favor of the continuous high-level enable signal recognizable continuous operating state.
  • Fig. 4 relates to Fig. 3 and shows in contrast the inventive method.
  • the ignition phase of FIG. 3 is preceded by a phase with a very small reference value U 0 , in which pulse bundles are likewise applied which contain test power pulses.
