Definitions

  • the invention relates to a method for determining operating parameters of a gas discharge lamp to be operated with an electronic ballast.
  • Such a method is according to EP 1519638 A1 known.
  • 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 invention has for its object to find a solution to the above problem.
  • the invention has for its object to provide a simple method for detecting the lamp type, which improves the detection reliability compared to the previously known methods.
  • the solution according to the invention adopts the principle of resistance measurement, preferably at heating power held constant during the preheating time or at constant heating current, and uses the difference value (distance) from hot and cold resistance instead of the hot resistances to determine the lamp type.
  • a certain heating power or a certain heating current is set. This can be done via the specification of a corresponding operating frequency and a corresponding switch-on time or a corresponding duty cycle. If the heating circuit is designed with a power source or current source characteristic, it can be ensured that during the preheating phase, the heating power or the Heating current sets in a certain window, which remains within a certain range of values.
  • the prior art has always used heating topologies or control methods with a voltage source characteristic or voltage regulation, which are far less suitable for the method operated here.
  • the invention is based on the following finding:
  • the measurement of the helical resistance via the helical current and the helical voltage presupposes that the helix is supplied with electrical power. This leads to the heating of the coil. Since the coils are usually made of metal, their resistance increases with temperature. The spiral temperature depends on the heating power supplied to the coil. In qualitative terms, this means that the higher the supplied heating power, the higher the coil resistance. It is now assumed that a second lamp type differs from a first lamp type in that the filament resistance of the second lamp type is twice as large as that of the first lamp type.
  • the filament of the second type of lamp is heated less than that of the first type of lamp.
  • the thermal resistance increase of the filament of the second lamp type is thus smaller than that of the filament of the first type of lamp. The thermal resistance increase thus counteracts the increase in the coil base resistance, with the result is that the detection reliability of the lamp type is reduced.
  • the thermal resistance increase of the Spiral of the second lamp type is higher than the thermal resistance increase of the filament of the first lamp type.
  • the thermal resistance enhancement enhances the effect of increasing the coil base resistance, with the result that the detection reliability of the lamp type becomes remarkable.
  • a further step can be added to the above-mentioned method steps, namely: Setting at least one operating parameter for the determined lamp type.
  • the formation of the differential resistance has the advantage that the influence of the starting temperature for measuring the cold resistance is eliminated.
  • the invention further relates to a ballast for at least one gas discharge lamp, with which the inventive method can be performed.
  • This ballast is characterized by the features of claims 10 and 14. Further developments are the subject of claims dependent on the claims 10 and 11 claims.
  • the current setting means may comprise a control part for the filament current.
  • a refinement of the ballast may consist in providing means for setting at least one operating parameter for the determined lamp type.
  • the measuring means may comprise a voltage divider connected in parallel with the filament, from which a signal corresponding to the filament voltage is derived.
  • To the control part may include a connected in series with the heating coil measuring resistor, from which a measurement signal is derived, which corresponds to the helical current.
  • ballast V is used to operate a gas discharge lamp L with two heating coils W1 and W2.
  • a rectifier 1 To generate the operating voltage for the lamp L 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 lamp L 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 led to the lamp L via a block 6, which contains means for limiting the filament voltage.
  • a limitation of the filament voltage is required, for example, a transverse discharge between the individual sections of the heating coils to avoid.
  • the filament current flowing through the "cold" filament W2 generates a voltage drop across the resistor R3, which is conducted to the filament current measuring means 7.
  • a voltage is further removed, which is a measure of the filament voltage at the "cold” coil W2. This is fed to the helical voltage measuring means 9.
  • 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 voltage are stored at two successive times during the preheating phase.
  • the stored measured values for the filament current and the filament voltage are fed from the memory 15 from a quotient former 10, which calculates therefrom the cold resistance and the hot resistance of the filament. These values are forwarded by the quotient generator 10 to the difference value generator 11, which calculates the differential resistance therefrom.
  • the difference value generator 11 supplies the differential resistance to a decision logic 13, which in turn corresponds to a memory 12 by storing a table for reference differential resistances.
  • the decision logic 13 compares the differential resistance calculated in the block 11 with the reference values in the table stored in the memory 12 and determines the type of the lamp L operated by the ballast V.
  • the determined lamp type is reported by the decision logic 13 to the operating parameter setting means 5, the next other operating parameters, among other things, the heating current or adjust the heating power, if the lamp L is of a different type than the previously operated with the ballast V lamp.
  • 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
  • Mains reset or emergency lighting operation is a brief interruption of the mains supply or a brief drop in the mains voltage, which results in a shutdown and a subsequent restart of the electronic ballast. Such a case can be caused by switching the network (by the utility) or by disturbances in the network.
  • An emergency lighting operation may e.g. in the event of mains voltage failure, switching on a (buffered) DC and AC supply voltage or switching to battery operation.
  • the differential resistance Rdiff is smaller than a predefined substitution resistance value Rsub. This comparison is to check whether the lamp is replaced for test purposes by a so-called substitution resistance, which shows no temperature-dependent resistance due to the thermal conditions. 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.
  • 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 1, then the decision is made that this is the lamp type 1.
  • 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 x 2 WW In the first coil, the cold resistance Rcold1 x 2 WW, and the hot resistance Rhot1 y 2 WW; where WW stands for a resistance value unit.
  • the cold resistance Rcold2 x 3 WW In the helix of the second lamp type, the cold resistance Rcold2 x 3 WW. During the pre-heating phase it rises to the hot resistance Rhot2 with x 5 WW.
  • the filament of the third lamp type starts with the cold resistance Rcold3 at x 4 WW. This resistance increases during the preheat phase to the hot resistor Rhot3 with x 11 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 resistances, allow identification of the lamp type with great certainty.
  • Fig. 4a shows the dependence of the coil resistance R w as a function of the filament voltage U w .
  • Two coils are considered, one having a helix resistance R 1 and the other having a helix resistance R 2 .
  • the coils are usually made of metal.
  • the electrical resistance of metal increases with temperature. Without taking into account the thermal resistance increase, the two helices form a parallel line to the abscissa, which is indicated by dashed lines. Taking into account the thermal resistance increase, the resistances of the two coils increase with increasing the filament voltage.
  • the supplied heating power with impressed helix tension P 1 U 2 w / R.
  • the supplied heating power with impressed filament voltage P 2 U 2 w / 2R.
  • the helix with the base resistance R 2 supplied heating power P 2 is thus only half as large as the heating power P 1 , which is supplied to the coil with the base resistor R 1 .
  • the two curves approach each other with increasing helix voltage U w . As a result, it becomes more difficult to distinguish between two lamp types having the different coil resistances R 1 and R 2 by the thermal resistance increase.
  • Fig. 4b now shows the idea underlying the invention, namely not to use an impressed filament voltage U w , but an impressed helical current I w .
  • a voltage originating from a low-voltage source predetermined coil voltage is applied to the coil, and that then the resulting helical current is measured.
  • the helical resistance R w then results from the product of filament voltage and filament current.
  • Fig. 5 shows a gas discharge lamp L, which is connected to an electronic ballast V formed according to the invention.
  • the ballast V includes a connected to the AC mains bridge rectifier 1, which rectifies the mains voltage, and a DC voltage intermediate circuit 2 supplies.
  • the intermediate circuit 2 is followed by a half-bridge inverter 3, the contains two alternately clocked switches.
  • the inverter 3 is followed by a pure resonant circuit, which consists of a choke and a capacitor.
  • the lamp is connected in parallel with the capacitor.
  • the circuit parts 1 to 4 are common and known in ballasts.
  • the ballast should now be designed so that with him fluorescent lamps L of different types can be operated.
  • the individual types differ not only by external dimensions, but also by different operating parameters, such as lamp current, lamp voltage, filament voltage, filament current, preheating, etc.
  • the ballast automatically detects the lamp type, by measuring the resistance at least one of the two filaments of the fluorescent lamp L.
  • the filament resistors of certain types are very close to each other, so that a distinction is difficult, and - as above in connection with Fig. 4a was explained by the thermal heating is still difficult.
  • the principle of the regulated helical current is used, which in connection with Fig. 4b has been described.
  • the coils of the lamp L Before the lamp type has been determined, the coils of the lamp L firstly a predetermined known Wendelstram must be supplied.
  • This helical current is either stored in the block 5 representing operating parameter setting means or in a starting program (or programmer) 14 which transmits the relevant current value to the block 5 when it receives a corresponding command from a center via the bus Usus.
  • the thus transmitted current value is supplied from the operating parameter setting means 5 a Wendelstromregier 8, which in turn causes Wendelschreibs-generating means 6, the two coils W1 and W2 of the fluorescent lamp L to supply a corresponding filament voltage.
  • the voltage applied to the lower coil W2 coil voltage is tapped with a consisting of the resistors R1 and R2 voltage divider and supplied to Wendelwoodsmessstoffn 9, which in turn pass the measured filament voltage value to a quotient-10.
  • the filament current flowing through the filament W2 is measured as a voltage drop across a resistor R3 and fed Wendelstrom measuring means 7, which in turn report the measured Wendelstromwert on the one hand to the quotient imager 10 and on the other hand as an actual value to the helical flow controller 8.
  • the quotient generator 10 calculates the filament resistance from the measured filament voltage value and the measured filament current value.
  • the helix resistance is supplied to comparison means (decision logic) 13 which compares it with the values stored in a table stored in memory means 12.
  • the table contains an associated coil resistance for each type of lamp to be operated with the ballast. This is compared with the measured coil resistance.
  • the comparison means (decision logic) 13 then report the determined lamp type to the operating parameter setting means 5.
  • Last then take the relevant settings on the ballast V before. vicarious this is in the Fig. 5 taken into account by the connection between the operating parameter setting means 5 and the inverter 3.
  • the clock frequency and / or the cycle times of the two switches of the inverter can be influenced in this way to set certain operating parameters.
  • the quotient generator 10 is dispensable per se. Instead of storing in the storage means 12 a table which contains the correspondence between coil resistance and lamp type, it is also possible to set down a table containing the associated filament voltage for each lamp type - with known preset coil current. In this case, the filament voltage measuring means 9 would have to report the measured filament voltage instead of the heating resistor to the comparator means (decision logic) 13. The message of the filament current measured by the filament current measuring means 7, which in Fig. 5 takes place at the quotient builder 10, then deleted.
  • a concrete realization of the helical voltage generating means 6 is shown. These include a flyback converter, consisting of an electronic switch S, a resistor R4 and an inductance, wherein the inductance of the primary winding of a heating transformer T H is formed.
  • the bus voltage U Bus lying on the bus is used as the DC voltage source. Instead of the bus voltage U bus , the output voltage of the intermediate circuit 2 can also be used.
  • the heating transformer T H has two secondary windings, each of which is intended for a filament of the fluorescent lamp L.
  • the AC voltage transmitted by the heating transformer T H is rectified by the diode 01 and 02 and by the Smoothed capacitors C1 and C2.
  • the capacitors C1 and C2 still have the task to contribute to the radio interference suppression.
