Definitions

  • the invention relates to a lighting system, ballasts, lights and methods for checking whether at least two to be operated with an electronic ballast (ECG) gas discharge lamps of the same type.
  • ECG electronic ballast
  • ballast gas discharge lamps with heating coils can be determined.
  • type thus also means the interconnection topology (serial / parallel) of several (preferably similar) lamps.
  • the voltage drop across a resistor located on the primary side of the heating transformer is measured at two different times during the preheating phase.
  • the two voltage values thus determined are compared with reference voltage values stored in a memory to determine the lamp type.
  • the lamp type is identified by measuring the current flowing through the filament. The current is measured during the preheat phase at two consecutive times.
  • the preheating phase therefore, there is a spreading of the resistance values to the effect that the distance or the difference of the hot resistances is twice as great as that of the cold resistances. Due to the greater distance of the hot resistors a more accurate determination of the lamp type is possible.
  • the prerequisite for this is that the power supplied to the filaments or the filament current supplied to the filaments be kept constant during the preheating phase.
  • an error signal can be output optically or acoustically or sent by means of a feedback via a digital interface. Such an error signal can be output in the event that an assembly with two different lamp types has been detected, or even in the event that an unreleased lamp has been connected to the ECG.
  • a special feature is the feature of claim 5, the independent inventive significance plays. According to this claim, for the determination of the lamp type, several sets of reference values are stored which apply to different preheating values, such as filament current, filament voltage or heating power, so that these parameters can be adapted to meet the lamp manufacturer's requirements or specifications.
  • a rectifier 1 To generate the operating voltage for the lamps L1, L2 is rectified by a rectifier 1, the mains voltage and smoothed in a smoothing circuit.
  • An inverter 3 generates an alternating voltage which is fed to a series resonant circuit 4. The voltage drop across the capacitor of the series resonant circuit 4 is supplied to the lamps L1, L2 as the operating voltage.
  • a programmer 14 connected to a bus determines the start of a preheat phase for the lamp L. He gives to the block 8 a start signal.
  • the block 8 generates the heating power or the filament current for the filaments W1 and W2 of the lamp L.
  • the heating power or the filament current are kept constant during the preheating phase.
  • the heating power or the filament current are passed to the lamps L1, L2 via a block 6, which contains means for limiting the filament voltage.
  • a limitation of the filament voltage is required to avoid a transverse discharge between the individual sections of the heating coils.
  • the filament current flowing through the "cold" coils W1b, W2b generates a voltage drop across the resistor R5, which is conducted to the filament current measuring means 7.
  • the measurement values continuously measured by the filament current measuring means 7 and the filament voltage measuring means 9 are fed to a memory 15.
  • the memory 15 is controlled by the programmer 14, such that the measured values for the filament current and the filament voltages are stored at two successive times during the preheating phase.
  • the stored measured values for the filament current and the filament voltages are fed from the memory 15 from a quotient generator 10 which calculates therefrom the cold resistances and the thermal resistances of the filaments. These values are forwarded by the quotient generator 10 to the difference value generator 11, which calculates the difference resistances from them.
  • the difference value generator 11 supplies the difference resistances to a decision logic 13, which in turn corresponds to a memory 12 by storing a table for reference difference resistances.
  • Decision logic 13 compares the difference resistances calculated in block 11 with the reference values in the table stored in memory 12 and determines the type of lamps L1, L2 operated by ballast V. The determined lamp type is reported by the decision logic 13 to the operating parameter setting means 5, which among other things reset the heating current or the heating power, if the lamps L1, L2 are of a different type than the previously operated with the ballast V lamps.
  • Further operating parameters may be the preheating time, the ignition voltage, the lamp burning voltage, the lamp current or else parameters for fault shutdowns. But there may also be operating parameters for the power factor correction circuit such as the Bus voltage or the dynamics of the control loop can be adjusted.
  • Fig. 2 concerns the case that two ballasts are operated in parallel with one ballast. Of course, it also includes the possibility of working with only one lamp.
  • the cold resistances Rcold1 and Rcold2 are measured by the two lamps. From the two measured values, the absolute value of the difference
  • the differential resistance Rdiff is smaller than a substitution resistance Rsub. This case is given when the lamp is replaced for simulation by such substitution resistance. If this is the case, the cold resistance and the hot resistance do not differ. Therefore, if the decision is "Yes", the differential resistance Rdiff is set equal to the hot resistance Rhot.
  • a special behavior deviating from normal operation can be triggered.
  • deviating operating parameters for the subsequent operation can be set for this case, whereby the preheating time or the sequence behavior of the lamp start can be changed, but the ballast can also be supplied with operating parameters via the recognized value of the substitution resistance for later operation, i. after the next lamp start.
  • This can be understood as a kind of programming of the ballast, whereby the respective types of the lamps to be detected can be specified.
  • An example of this may be that a ballast has stored the parameter sets for combining a 14W and 24W lamp and the combination of a 21W and 39W lamp.
  • the ballast can later distinguish between a 14W and 24W lamp or a 21W and 39W lamp, thus avoiding the problem that the 14W lamp and the 21W lamp can not be distinguished by their coils.
  • the decision is whether the differential resistance Rdiff is smaller than a first stored resistance value "Level 1". If Difference resistance Rdiff is less than this level is 1, then the decision is made that this is the lamp type 1.
  • the setting of the lamp parameters is continued according to the determined lamp type.
  • Lamp type detection also optionally means that the number of parallel discharge lamps (or similar) supplied by the operating device can be determined using heating coils, ie “type” or “lamp type” also includes the interconnection topology (serial / parallel) of several ( preferably similar) lamps.)
  • Fig. 3 shows the course of the filament resistance in three different lamp types during the preheat phase, which takes 500 ms.
  • the cold resistance Rcold1 is 2 WW
  • the hot resistance Rhot1 is 3.88 WW; where WW stands for a resistance value unit.
  • the cold resistance Rcold2 is 4 WW. It rises during the preheat phase to the hot resistor Rhot2 with 14 WW.
  • the filament of the third lamp type starts with the cold resistance Rcold3 at 8 WW. This resistance increases during the preheat phase to the hot resistor Rhot3 with 40 WW.
  • a difference resistance Rdiff1 of 1.88 WW results for the first lamp type.
  • the differential resistance Rdiff2 of the second lamp type is 10 WW.
  • the differential resistance Rdiff3 for the third lamp type is 32 WW.
  • the spreading of the hot resistors Rhot1, Rhot2 and Rhot3 makes it possible to define for the differential resistors Rdiff1, Rdiff2 and Rdiff3 variation ranges which are spaced from each other.
  • the variation ranges are marked with hatching lines.
  • a secure identification is in any case given if the determined difference resistance of the heating coil of a lamp falls into one of the three hatched areas.
  • the first level “level 1" is identical to the cold resistance Rcold1 of the first lamp type.
  • the second level “level 2” is identical to the hot resistance Rhot2 of the second type of lamp.
  • the third level “level 3” lies with a considerable distance above the hot resistance Rhot3 of the lamp type.
  • dashed lines show that the ranges of determination for the relevant lamp type extend beyond the lower undefined range to the next level.
  • the identification zones that go beyond the hatched areas are not compulsory, but have been chosen on a case-by-case basis. It is essential that the hatched areas, ie the variation ranges for the differential resistors allow identification of the lamp type with great certainty.

Abstract

L'invention concerne un procédé destiné à contrôler si au moins deux lampes à décharge gazeuse (L1, L2) destinées à fonctionner avec un ballast électronique (V) sont du même type. A cet effet, la tension et le courant d'un filament de chauffage respectif (W1b, W2b) de chaque lampe à décharge gazeuse (L1, L2) sont mesurés à un premier instant et les résistances de filament (R1cold, R2cold) sont calculées à partir de ces mesures. La résistance différentielle absolue (IRdiff l) est ensuite calculée à partir des résistances de filament (R1cold, R2cold). La résistance différentielle absolue est comparée à une valeur de référence supérieure et à une valeur de référence inférieure. La comparaison permet de déterminer si les deux lampes à décharge gazeuse (L1, L2) sont du même type.
