Definitions
- the invention relates to the AC operation of discharge lamps with electronic ballasts.
- ballasts contain high-frequency converters for generating an AC power supply for the lamp from a low-frequency mains supply or else from a DC voltage supply.
- EOL monitoring end-of-life monitoring
- a circuit part of the ballast monitors when a life end of one of the electrodes of the operated discharge lamp is announced.
- EoL-Uberwachungsscrien are known per se, such as from WO 00/11916, to which reference is made to explain the technical background.
- the EoL monitoring utilizes the rectifying properties of the discharge lamp, which are established with the approaching end of the electrode life.
- the electrode end of life goes with a consumption or a Degradation associated with an electron emitting material. More generally, the end of life of an electrode is indicated by an increase in electron work function at that electrode. This results in an asymmetry in AC operation or otherwise expressed a unipolar additional power in the lamp with a corresponding asymmetric voltage drop.
- the object of the present invention is to specify an improved electronic ballast for discharge lamps with regard to EoL monitoring.
- the invention relates firstly to an electronic ballast for the AC operation of a discharge lamp with an EoL monitoring circuit for detecting the end-of-life of the electrodes of the discharge lamp, which EoL monitoring circuit responds to an a-symmetrical output of the discharge lamp, characterized in that the EoL monitoring circuit is supplied with a current connected to the asymmetrical power and a reference current is supplied to a current differential amplifier,
- the basic idea of the invention is not one with the beginning of the same derive correlative voltage from the directing properties of the discharge lamp to detect via a voltage-sensitive amplifier circuit and to use for controlling the operation of the ballast, but instead to make a current difference gain.
- a current correlated with the asymmetrical power of the discharge lamp is used and fed together with a reference current to a current difference amplifier.
- the current differential amplifier is characterized by the fact that, even if there is no EoL detection, that is, no rectifying properties can still be detected, it allows input currents. This can be avoided in particular that, in the case of voltage-sensitive inputs with transistors switching through in an EoL detection resulting from the current load of resistors, with which corresponding measurement voltages for detection or reference voltages are generated for comparison, voltage shifts.
- the necessary measuring current and the reference current can be printed to such low values that the associated power consumption is completely insignificant.
- suitable operating points can easily be set by appropriate preloads, for example by feedback couplings at the current difference amplifier.
- a preferred embodiment of the input of the current difference amplifier is a current mirror circuit known per se, wherein the current difference amplifier is particularly preferably otherwise constructed as an operational amplifier.
- Such op-amplifiers with mirror input are available, for example, as so-called Norton amplifiers from the manufacturer Motorola, today “On Semiconductors”.
- This Norton amplifier also has a voltage output and thus shows another preferred feature of the invention.
- this is an amplifier with a MOSFET current mirror input, a favorable embodiment of such a current mirror input.
- current mirror inputs can also be embodied in other unipolar technology or else in bipolar technology.
- An output signal of the current difference amplifier can be given in a simple and favorable embodiment of the invention to a window comparator, that is, a combination of two simple comparators between whose thresholds results in a corresponding window.
- the output signals of the comparators can, for example, be linked via a NAND gate and connected to a switch-off point. be taken in the direction of the detection of an end of the electrode life, the high-frequency converter out of operation.
- the EoL monitoring circuit preferably has a low-pass filter, for example an RC element.
- the capacitor of the RC element can lie in a favorable embodiment between the measuring current input of the current differential amplifier and the ballast internal reference potential.
- a microprocessor sampling of the current difference amplifier can be provided, which scans at certain intervals and possiblyteurbowt in the case of EoL detection for security reasons repetition queries.
- reaction times for EoL monitoring circuits prescribed by standardization and / or the technical boundary conditions are not particularly short but as a rule a few seconds are available.
- One way to generate a reference current for the current differential amplifier is to use a relatively high-impedance resistor from a reference potentiometer. al to derive a current, in particular from the upstream high-frequency converter.
- the current differential amplifier which incidentally relates to this reference potential, can be connected in a favorable manner via resistors with a tap between the coupling capacitor and the discharge lamp so as to tap a current correlating with the voltage across the coupling capacitor. It should be noted that the inputs of the current differential amplifier are potentially very close to the reference potential.
- Another practically important interconnection provides for a corresponding coupling capacitor between the AC output of the high-frequency converter and the discharge lamp and accordingly switches the other terminal of the discharge lamp, as a rule, directly to the reference potential.
- a corresponding coupling capacitor between the AC output of the high-frequency converter and the discharge lamp and accordingly switches the other terminal of the discharge lamp, as a rule, directly to the reference potential.
- such circuits may be of particular advantage in order to be able to measure the lamp current in a simple and direct manner and to use it, for example, for current regulation.
- it is convenient to measure the measuring current for the current differential amplifier which in turn is based on the reference potential again derive from a center tap between the coupling capacitor and the discharge lamp via a resistor.
- This measuring current then correlates with the lamp voltage, ie, it would lie smoothly in pure AC operation at a mean value of zero.
- the corresponding measuring current input of the current difference amplifier can be biased, for example, via a feedback from the amplifier output, to which reference is also made to the second exemplary embodiment.
- the invention also has a method aspect and accordingly also relates to a method for alternating-current operation of a discharge lamp with such a ballast, in which method the end-of-life of an electrode of the discharge lamp is monitored by an EoL monitoring circuit which responds to an asymmetrical output of the discharge lamp is detected, characterized in that in the EoL monitoring circuit connected to the asymmetric power and a current reference current to a current difference amplifier are supplied.
- FIG. 1 shows a simplified circuit diagram of a ballast for a low-pressure discharge lamp as a first exemplary embodiment.
- Figure 2 corresponds to Figure 1 and shows a second embodiment.
- Figure 3 corresponds to Figure 1 and shows a third embodiment.
- FIG. 1 shows a circuit diagram of a ballast according to the invention for a low-pressure discharge lamp LA1, which is likewise shown in the right-hand area and is connected to the input terminals KL1-I and KL1-2 in the left-hand area for a conventional household power supply with a phase line L and a neutral conductor N.
- the inductor LD2 and the capacitor C5 form an RFI filter between the rectifier Dl to D4 and an intermediate circuit storage capacitor C6, via which the intermediate circuit voltage is applied with a lying in the lower part of the figure ballast reference potential and a lying in the upper range ballast internal supply potential.
- each freewheeling diodes Dil and D12 are connected in parallel and by a so-called trapezoidal capacitor C8 between its center tap and the Supply potential are relieved switching.
- the control connections in this case the bases of the biopolar transistors T1 and T2, are driven via secondary windings RK1-B and RK1-C as well as resistors R3 and R4, a primary winding RK1-A with the secondary windings RK1-B and RK1-C is coupled and between the aforementioned center tap and thus AC output of the half-bridge and the lamp LAl is located.
- the Lamp LAl is a common lamp inductor LDL.
- the lamp LA1 is connected via lamp terminals KL2-1 to KL2-4, whereby the terminals KL2-3 and KL2-4 are provided on the middle tap side and the terminals KL2-1 and KL2-2 are provided on the other side of the lamp and between the terminals KL2- 2 and KL2-3 a necessary to ignite the lamp in a conventional manner necessary resonance capacitor C9 is connected.
- the lamp terminal KL2-1 is connected via a likewise known coupling capacitor ClO to the reference potential, so that during operation, a mean charging of the coupling capacitor ClO results on the half DC bus voltage across the DC link capacitor C6 and the lamp LAl thus symmetrically in order the potential, which oscillates at the upper terminal of the coupling capacitor ClO, can be operated in a pure alternating-current operation.
- the part of the circuit described so far is conventional in nature and is therefore not explained in detail.
- the inventive EoL monitoring circuit will be discussed. This has an op-amp Ul with current mirror input, here a so-called Norton amplifier LM 3900 of On Semiconduc- tors.
- a reference current derived from the supply potential via a high-resistance resistor of 10 M ⁇ is applied to the inverting input (designated by a "-") via a likewise high-resistance resistor R2 of FIG. 5 M ⁇ from a tap between the coupling capacitor ClO and the lamp terminal KL2-1 derived measuring current.
- the difference between the two is amplified in a conventional manner, wherein the amplifier Ul is connected via a resistor R9 of 813 k ⁇ between its output and its inverting input in a conventional manner ruckkoppelnd.
- the output signal of the amplifier U1 is applied to a window comparator consisting of a first comparator U2-A and second comparator U2-B, in which it is compared with a threshold window between 3.5 V and 8.5 V in this case. Accordingly, the inputs of the comparators U2-A and U2-B are connected to a NAND gate U3-A, the output of which indicates whether or not the current difference is within the tolerance width defined by the two comparator threshold values.
- This signal is supplied to a turn-off device AE, which in response to this signal controls the base drive of the lower switching transistor T2 of the half-bridge device. converter prevents, which then also omit the switching operations of the upper switching transistor Tl.
- the amplifier Ul Since the amplifier Ul is related to the reference potential and as a result of its current mirror input only low voltages at its inputs relative to the reference potential builds (less than 1 volt in the rule) corresponds to the current flowing through the resistor R2 current in the inverting input of the amplifier Ul practically proportional to the voltage above the coupling capacitor ClO.
- the current flowing into the inverting input is composed of this current and the current through the feedback capacitor R9.
- the resistors R2 and R9 are dimensioned so that in equilibrium without asymmetric EoL voltage component on the coupling capacitor ClO the output of the amplifier Ul to about half of the arithmetic mean of the reference potentials at the inputs of the window comparator U2-A, U2-B of FIG V is. In the lying case, turn-off potentials of about +/- 20 V at the coupling capacitor ClO.
- FIG. 2 shows an embodiment which is largely identical to FIG. 1, but with a different connection of the coupling capacitor ClO and therefore also a slightly different connection of the amplifier U1. It is therefore first made to the comments on Figure 1 reference. Deviating from this, however, the coupling capacitor C10 is here between the primary winding RK1-A and the lamp inductor LD1 and thus between the alternating current output of the half-bridge converter with the switching transistors T1 and T2 of the lamp LA1.
- the measuring current is taken off via the resistor R2 dimensioned here by 1.5 M ⁇ from a tap between the lamp inductor LD1 and the lamp LA1. Since the DC voltage component across the resistor R2 is significantly smaller than in the first embodiment, the reference potential for the reference current is taken here with 6 V from an already available for control circuits of the ballast supply and adapted the corresponding resistor Rl. In this embodiment, the optional capacitor C2 (shown in dashed lines in FIG. 1) must be provided for the low-pass smoothing.
- Figure 3 largely corresponds to Figure 1, so again reference is made to the explanations there.
- the window comparator U2-A, U2-B and the NAND gate U3-A are omitted between the amplifier Ul and the turn-off device AE.
- the turn-off device has a microprocessor ⁇ P, which scans the output of the amplifier Ul at certain time intervals and in the case outside of a predetermined window of here again 3.5 V to 8.5 V lying output signalsteurchtt a repeat measurement for safety and then initiates a shutdown process.
- the invention can therefore also be combined with a microprocessor control.
- the control of the switching transistors Tl, T2 and the assumption of other functions of the ballast can of course also be microprocessor-controlled.
