Definitions

  • the present invention relates to a circuit arrangement for operating at least two gas discharge lamps according to the preamble of claim 1.
  • each only one drive only gas discharge lamp is that a large part of the Components of the ballast, such as the rectifier, the Harmonic filter, the control circuit and the inverter for operating multiple Lamps can be used simultaneously.
  • the inverter and the load circuit of a known two-lamp ballast which is disclosed in EP 0 490 329 A1, are shown schematically in FIG. 4 and will be briefly explained below.
  • the inverter is formed by two controllable switches S1 and S2, which are arranged in a half-bridge arrangement, at the input of which a DC supply voltage V BUS is present. From a control circuit 1, the two switches S1 and S2 are driven so that they alternately open and shoot, so that at the midpoint of the half-bridge results in a high-frequency AC voltage U ac .
  • This alternating voltage is supplied to the load circuit, which initially has on the input side a series resonant circuit consisting of an inductance L a and a capacitor C r .
  • the two gas discharge lamps LA1 and LA2 are each connected in parallel via a coupling capacitor C k1 or C k2 .
  • the two gas discharge lamps LA1 and LA2 is preceded by a balancing transformer L bal whose windings are traversed by the two lamp currents. This occurs in opposite directions, so that in the case of deviations of the current amplitudes, a magnetization is produced which induces a voltage in the windings, which in turn acts in a symmetrizing manner.
  • the balancing transformer L bal thus component tolerances and lamp tolerances and different temperature conditions, which would result in that the two lamps LA1 and LA2 burn with different brightness, can be compensated to a certain extent.
  • the balancing effect of the transformer L bal is limited and does not ensure complete alignment of the lamp currents.
  • the lamps are connected in parallel at low currents, which result at low dimming levels, since the voltage drop across the balancing transformer can only be a fraction of the burning voltage of the lamps. This is particularly evident at lower temperatures, where the burning voltage reaches a maximum with small lamp currents.
  • the two lamps are to be operated at a brightness which corresponds to a certain nominal current I SOLL .
  • I SOLL nominal current
  • both lamps are not identical, but have slightly shifted characteristic curves U arc1 and U arc2 , as shown in FIG.
  • the second lamp generally requires a slightly higher burning voltage U arc2 than the first lamp for a given current. Therefore, in order to be able to operate both lamps with the nominal current I SOLL , two different burning voltages U SOLL1 and U SOLL2 would be required.
  • the ballast with the inverter only provides a voltage value U SOLL1 , which is determined in the example shown by the lamp with the lower burning voltage, ie by the first lamp with the characteristic U arc1 , this voltage U SOLL1 is also at the second Lamp on.
  • the second lamp does not assume the desired current value I SOLL , but possibly forms a second operating point with a different current value I arc2 and thus of course also with a different brightness.
  • the second lamp with the higher operating voltage may not be able to form a fixed operating point and, as a result, it will disappear.
  • the control of the inverter always takes place in the case of the ballast shown in FIG. 4 after that lamp LA1 or LA2, which currently has the lower lamp current.
  • the ballast on two detection circuits 2 1 and 2 2 each detecting the current flowing through a lamp LA1 and LA2 current by determining the drop across a measuring resistor R SENS1 or R SENS2 voltage.
  • the actual values V IST1 and V IST2 generated by the two detection circuits 2 1 and 2 2 are then fed to a comparison circuit 3, which selects the correspondingly lower value and forwards the final actual value V IST to the control circuit 1 for controlling the inverter.
  • From DE 42 43 955 A1 is a ballast for at least one parallel operated Gas discharge lamp pair known, showing the features of claim 1.
  • n is integer and greater 1
  • gas discharge lamps with a operated with a single inverter, which is fed with a DC voltage and generates a variable in their frequency AC voltage, the one on the Output of the inverter arranged load circuit is supplied.
  • the load circuit contains one consisting of an inductance and a capacitance Series resonant circuit and the n to the common node between the Inductance and the capacity of connected gas discharge lamps. Further contains the load circuit (n-1) balancing transformers for balancing the currents of two gas discharge lamps each.
  • the load circuit points to each Gas discharge lamp on a DC power supply line, respectively between the output side terminal of the winding of the balancing transformer and the gas discharge lamp attacks and over each gas discharge lamp DC is supplied.
  • This additional direct current preferably corresponds approximately to half of the nominal 1% current at 25 ° C - 35 ° C. He causes, even in the event that due to the predetermined AC voltage can not form a stable operating point, none of Lights go out.
  • the additional direct current also prevents this Occurrence of so-called running layers.
  • the measures according to the invention can extinguish the lamps reliably prevented. However, it may be due to more asymmetrical Wiring and lamp capacities come to large brightness differences, since the balancing transformers attempt the relatively large currents and consequently in a lamp with less wiring capacity an additional active current is generated. To avoid this and a better one Symmetrization of the lamp currents can, according to another Development of the invention, the two windings of a balancing transformer each by a series connection of a capacitor and a resistor be connected to each other. This has the consequence that the balancing effect of Transformers is reduced for small lamp currents, without causing the DC sources are affected. The reduction of the balancing effect works only on the AC components of the lamp voltage, so only on that part, which at low levels of dimming is predominantly asymmetrical Wiring capacity is affected.
  • the circuit according to the invention is characterized in that it in a simple manner be extended from a two-lamp system to a multi-flame system can. In addition, it is no longer necessary for each lamp its own Provide detection circuit for measuring the lamp current. Rather, it is sufficient to use only a single detection circuit, which the Sum of the active powers of the arranged in the load circuit gas discharge lamps detected and generates a corresponding actual value. Based on a comparison between this actual value and a predetermined setpoint can then Inverters are controlled. The capture of the sum of the active services can For example, in a half-bridge inverter in a simple way take place that arranged over a arranged at the base of the half-bridge measuring resistor declining voltage is determined.
  • the invention proposed DC power supply lines with the in Series to the lamps switched resistors, which input side to a common supply voltage can also be connected multi-lamp systems are used in which no Balanced transformers are provided.
  • a corresponding circuit arrangement is the subject of claim 9.
  • the circuit arrangement shown in FIG. 1 is similar in its basic structure to the known circuit shown in FIG. Again, only one single inverter consisting of two controllable switches S1 and S2 is provided for operating the two gas discharge lamps LA1 and LA2.
  • the arranged in a half-bridge arrangement switches S1 and S2 are supplied with a DC voltage V BUS and generate by alternately opening and closing a high-frequency AC voltage U ac , which is supplied to the load circuit.
  • the load circuit contains the series resonant circuit consisting of the inductance L a and the capacitance C r , at the center of which the two lamps LA 1 and LA 2 are connected via two coupling capacitors C k1 and C k2 .
  • the lamps LA1 and LA2 are preceded by a balancing transformer L bal .
  • the DC power supply lines according to the invention are each connected to a point between the lamp LA1 or LA2 and the output side of the corresponding winding of the balancing transformer L bal . They each contain a resistor R dc1 or R dc2 connected in series to the corresponding lamp LA1 or LA2 and are connected on the input side to a common DC voltage source. The resistance values for the two resistors R dc1 and R dc2 are identical.
  • the DC voltage source is formed in the example shown by a connected to the output of the inverter diode D1 and a grounded capacitor C dc as a low-pass filter, which form of the high-frequency AC voltage U ac a smoothed DC voltage U dc .
  • the direct current supplied to the second lamp LA2 results analogously.
  • the two resistors R dc1 and R dc2 are designed so that the additional direct current in about half of the nominal 1% current at 25 ° C corresponds to 35 ° C.
  • the recovery of the DC voltage U dc from the AC voltage U ac of the inverter has the further advantage that after switching off the inverter and the lamps LA1 and LA2 supplied DC power is deactivated, so that both lamps LA1, LA2 are turned off safely.
  • the direct current supplied to the lamps LA1, LA2 also prevents the occurrence of so-called running layers.
  • the balancing effect of the transformer L bal only works up to a certain dimming level. At brightness values below this dimming level, the lamp current is so low that capacitive currents that are greater than the lamp currents themselves can arise. These capacitive currents can arise, for example, due to the fact that the supply lines of the lamps are laid asymmetrically, as a result of which additional wiring capacities C par and thus capacitive currents I par occur, as shown schematically in the second lamp LA2. If these capacitive currents I par are greater than the lamp currents, the balancing transformer L bal reacts in such a way that the asymmetry is increased. The lamp LA1, which does not have the additional wiring capacity, is then supplied with an additional active current I arc1 , which can be estimated in the following way: I arc 1 ⁇ I arc 2 2 + I par 2
  • the balancing effect of the transformer L bal is to be reduced for low lamp currents, without this affecting the DC sources.
  • This is achieved in that the two output-side terminals of the windings of the balancing transformer L bal by a frequency-dependent impedance, which consists in the present example of the series connection of a resistor R bal and a capacitor C bal , are interconnected. This connection allows a certain balance of small asymmetries.
  • the reduction of the balancing effect has an effect only on the AC component of the lamp voltage, ie only on that part which is responsible for the capacitive currents at small dimming levels.
  • FIG. 1 The effect of the circuit according to the invention is shown schematically in FIG.
  • the graph shown here shows the voltage applied to the lamps LA1 and LA2 and time-varying lamp voltage U arc1 and U arc2 .
  • U ac1 or U ac2 is still supplied to both lamps, since they are now DC-decoupled, they can assume a different DC voltage component U dc1 or U dc2 .
  • each lamp can exactly take on the voltage that it would have to form for the given brightness value or lamp current. This provides the ability to drive both lamps through a single inverter and still operate both at the desired brightness.
  • FIG. 3 illustrates the extension of the system to three gas discharge lamps LA1, LA2 and LA3.
  • the extension consists merely in that now several balancers L bal12 and L bal23 are used, which respectively symmetrize the currents of two lamps LA1 and LA2 or LA2 and LA3.
  • L bal12 and L bal23 are used, which respectively symmetrize the currents of two lamps LA1 and LA2 or LA2 and LA3.
  • R or R bal12 bal23 to cause the output-side terminals of the balancing transformers bal12 L and L bal23 over the previously described series combination of a resistor R or R bal12 bal23 and a capacitance C bal12 or C bal23 connected to a decoupling of the DC components.
  • An extension of the system to n gas discharge lamps is then only that (n-1) balancing transformers are used, which each symmetrize the currents of two lamps.
