Definitions
- the invention relates to a method for determining the type of a gas discharge lamp to be operated with an electronic ballast.
- EP 1125477 B1 it is known to determine the filament resistance of the lamp in order to determine the lamp type by comparison with a reference resistance value stored in a register.
- the identification of the lamp type is carried out by measuring the current flowing through the filament.
- the current is measured during the preheat phase at two consecutive times.
- German patent application DE 10 2007 047 142.6 which has not yet been published, it is proposed to use the measured value of the helical resistance for determining the lamp type, although this is a prerequisite is that the power supplied to the heating coil or the supplied filament current are kept constant during the preheating phase.
- the coils heat up. With the heating also increases the coil resistance. For example, if the filament of a first type of lamp has the cold resistance R, it may double during the preheating phase, for example 2R. Now, if the filament of a second lamp type has the cold resistance 2R, its hot resistance would be 4R.
- 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.
- lamp type detection also means that the number of gas discharge lamps with heating coils supplied in parallel or in series by the operating device can be determined.
- the object is achieved by the combination of the features specified in the characterizing part of claim 1.
- the solution according to the invention adopts the principle of resistance measurement with heating power held constant during the preheating time or with a constant heating current.
- the difference resistance is formed from the measured hot resistance and the measured cold resistance, which in any case is independent of the starting temperature, if a helical voltage limiting has not yet been used.
- the optional detection of a substitution resistance as a substitute load can trigger a special behavior deviating from normal operation.
- deviating operating parameters for the subsequent operation can be set for this case, wherein, for example, the preheating time or the sequence behavior of the lamp start can be changed, but the electronic ballast can also have operating parameters on the detected value of the substitution resistance for later operation, ie after next lamp start, be specified.
- This can be understood as a kind of programming of the TOE, whereby the respective types of the lamps to be recognized can also be specified.
- An example of this may be that an ECG has stored the parameter sets for combining a 14W and 24W lamp and the combination of a 21W and 39W lamp.
- the ECG can later differentiate between a 14W and 24W lamp or a 21W and 39W lamp.
- the solution according to the invention allows the reference values for the differential resistances to cover a defined variation range for each lamp type.
- a determination of the lamp type is in any case possible if the determined differential resistance falls within one of these ranges of variation. If there is an undefined distance range between two variation ranges and a determined differential resistance falls within this distance range, the lamp type which was last recognized unambiguously can be selected for determination. Alternatively, however, it is also possible to select the lamp type for the determination whose allocated variation range is adjacent to the distance range and covers differential resistances which are smaller than the determined differential resistance.
- the invention further relates to a ballast for at least one gas discharge lamp, which is suitable for carrying out the method according to the invention.
- a ballast for at least one gas discharge lamp, which is suitable for carrying out the method according to the invention.
- the features of such a ballast are specified in claim 11.
- the number of parallel and / or serially supplied by the operating device gas discharge lamps of a certain type can be detected. For this purpose, it is checked, for example, whether the validated differential resistance corresponds to n times one of the several corridor ranges. If so, it can be concluded that n lamps of the lamp type are connected in series at the output of the operating device, which is assigned to this corridor area.
- Fig. 1 is a schematic block diagram of the ballast according to the invention.
- Fig. 2 is a flow chart showing how the method of the invention is practiced
- Fig. 3 is a graph showing the dependence of filament resistance on the preheat time for three different lamp types, and the resulting three ranges of variation for the differential resistance of each of these three lamp types;
- the ballast V shown in Fig. 1 is used to operate a gas discharge lamp L with two heating coils Wl 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 Wl 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 to avoid a transverse discharge between the individual sections of the heating coils.
- 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 the Wendelwoods- measuring means 9 supplied.
- the measured values continuously measured by the filament current measuring means 7 and the filament voltage measuring means 9 are supplied 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 of 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, which, inter alia, readjust the heating current or the heating power, if the lamp L is of a different type than the previously operated with the ballast V lamp.
- Further operating parameters may be the preheating time, the ignition voltage, the lamp burning voltage, the lamp current or else parameters for fault shutdowns.
- Fig. 1 it is also possible to set operating parameters for the power factor correction circuit, such as, for example, the bus voltage or the dynamics of the control loop.
- operating parameters for the power factor correction circuit such as, for example, the bus voltage or the dynamics of the control loop.
- the individual blocks in Fig. 1 need not necessarily be realized by hardware. Rather, it is also possible that the function of some blocks is realized by a corresponding software in a processor.
- the block diagram in Fig. 1 is intended only for better understanding.
- Fig. 2 relates to the case that two lamps are operated in parallel with a ballast. Of course, it also includes the
- the cold resistances Rcoldl and Rcold2 are measured by the two lamps. From the two measured values, the absolute value of the difference
- Differential resistance limited be it the lamp with the coil with the lower cold resistance or the single
- the differential resistance Rdiff is smaller than a predefined substitution resistance Rsub. This case is given when the lamp is replaced by such substitution resistance for testing purposes. 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 in this case, whereby the preheating time or the sequence behavior of the lamp start are also changed can, the ballast but also operating parameters on the detected value of the substitution resistance for later operation, ie after the next lamp start, be specified.
- 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 1, then the decision is made that this is the lamp type 1.
- level 1 level 1
- level 2 level 3
- the setting of the lamp parameters is continued according to the determined lamp type.
- Fig. 3 shows the course of the helical resistance in three different lamp types during the preheat phase, which lasts 500 ms.
- the cold resistance is Rcoldl 2 WW
- the hot resistance Rhotl is 3.88 W
- 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 differential resistance Rdiffl of 1.88 W results for the first lamp type.
- the differential resistance Rdiff2 of the second lamp type is 10 W.
- the differential resistance Rdiff3 for the third lamp type is 32 W.
- the spreading of the hot resistors Rhotl, Rhot2 and Rhot3 makes it possible to define for the differential resistors Rdiffl, 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 Rcoldl of the first lamp type.
- the second level “level 2” is identical to the hot resistance Rhot2 of the second lamp type.
- 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 shaded areas, ie the variation ranges for the differential resistances one. Allow identification of the lamp type with great certainty.
- the validated differential resistance of the heating coil is compared with predetermined ranges.
- this approach can also be used to the number of parallel and / or serially supplied by the operating device gas discharge lamps. Even with such a multi-lamp application can continue to be concluded on the type of lamp used (ie, the associated operating parameters, for example. For the preheating, ignition and / or burning operation set), as long as a uniform type of lamp is used.
