Definitions

  • the invention relates to a method for operating fluorescent lamps according to the preamble of patent claim 1.
  • the EP 0 287 360 A2 discloses an apparatus for operating a laser diode.
  • the device comprises at least two D / A converters, with the aid of which at least two control loops for coarse and fine adjustment of the light emission of the laser diode are realized.
  • the US 4,894,587 describes a ballast for high-frequency operation and for brightness control of fluorescent lamps.
  • the inventive method for operating fluorescent lamps by means of a ballast having an inverter with semiconductor switches, which are arranged in a bridge circuit, and with a control device for the semiconductor switches and at least one connected to the inverter, designed as a resonant circuit load circuit, in the at least one Fluorescent lamp is operated, wherein the at least one fluorescent lamp is acted upon by the inverter with a high-frequency current and the power consumption of the at least one fluorescent lamp by means of a first control loop by varying the frequency of the high-frequency current is set to a predetermined value, characterized in that by means of a second control loop which is run through in shorter time intervals than the first control loop, the power consumption of the at least one fluorescent lamp is stabilized to the predetermined value.
  • the second control loop ensures that the fluorescent lamps can be safely operated even in the critical power range corresponding to approximately 25% to 10% of their rated luminous flux, without the occurrence of significant fluctuations in the power consumption or brightness of the fluorescent lamps.
  • the second control loop is run in much shorter time intervals than the first control loop and can therefore counteract rapid changes in the power consumption of the fluorescent lamps, as they can occur in the aforementioned critical range.
  • the time intervals for passing through the second control loop are advantageously 50 ⁇ s to 200 ⁇ s, while the time intervals for passing through the first control loop are preferably significantly longer, preferably with 1 ms to 2 ms.
  • the method according to the invention is advantageously for the implementation of the first control loop adjustable in size setpoint at predetermined time intervals compared with an actual value, which is derived from the time average power consumption of the at least one fluorescent lamp, and formed therefrom a first control value for the control device, while Execution of the second control loop at predetermined time intervals, which are shorter than the time intervals of the first control loop, the change in power consumption of the at least one fluorescent lamp for generating a second control value for the control device is evaluated, and both control values for generating control signals for the control of the switching frequency Semiconductor switches are evaluated.
  • control variables for both the first and the second control loop are derived from the current flowing through the bridge circuit because the time average of this current is proportional to the power consumption of the fluorescent lamps.
  • the control variables, that is to say, the actual values of both control loops are derived, for example, by means of low-pass filters from the current flowing through the bridge circuit, the time constant of the second low-pass filter belonging to the second control loop being smaller than the time constant of the first low-pass filter belonging to the first control loop.
  • the time constants are each adapted to the abovementioned time intervals of the control loops.
  • the functions of the two low-pass filters are each taken over by a digital filter which operates with different sampling frequencies adapted to the abovementioned time intervals.
  • digital filters simplifies the structure of the circuit arrangement, because they can be formed as part of a microprocessor.
  • the second control loop is designed as a nominal actual value comparison, which is repeated continuously at predetermined time intervals, wherein at the end of each time interval, the current flowing through the bridge circuit Current is derived from an actual value and this is compared with the actual value of the immediately preceding time interval serving as a setpoint, in order to generate therefrom the second control value for the control device of the inverter.
  • the ballast for carrying out the method according to the invention comprises an inverter with Halbieiterschaltern, which are arranged in a bridge circuit, a control device for the semiconductor switches and at least one connected to the inverter, designed as a resonant circuit load circuit with terminals for at least one fluorescent lamp, wherein the control device comprises means for Variation of the switching frequency of the semiconductor switch has to set the power consumption of the at least one fluorescent lamp to a predetermined value, and the control device has means for stabilizing the power consumption of the at least one fluorescent lamp to the predetermined value.
  • the means for stabilizing the power consumption of the at least one fluorescent lamp are preferably called differential regulators, also called D-regulators, which monitors the change in power consumption of the at least one fluorescent lamp at predetermined time intervals and in dependence thereon a manipulated variable for the stabilization control apparatus the power consumption is generated to the specifiable value.
  • the ballast according to the invention preferably has a, compared to the D controller slow proportional-integral controller, also called PI controller, on which the time-average power consumption of at least compares a fluorescent lamp with a predefined setpoint.
  • Both controllers are advantageously designed as part of a microprocessor, which in turn is part of the control device.
  • the control values generated by both controllers; are superimposed and stored in a digital data register of the microprocessor.
  • FIG. 1 schematically the construction of an electronic ballast for erfindungsgcmäßcn operation of a fluorescent lamp is shown.
  • This ballast has a half-bridge inverter with two half-switches, in particular transistors T1, T2, a control device ST for the semiconductor switches T1, T2 and two terminals +, - for the DC power supply of the half-bridge inverter.
  • a trained as a resonant circuit load circuit is connected at the center tap M of the half-bridge inverter .
  • the load circuit comprises the resonance inductor L1, the resonance capacitor C1, the coupling capacitor C2, the discharge resistor RI arranged parallel to the coupling capacitor C2, and connections for the electrode filaments E1, E2 of a fluorescent lamp LP.
  • the fluorescent lamp LP is arranged in the load circuit such that its discharge path is connected in parallel to the resonance capacitor C1 and the electrode coils E1, E2 are connected in series with the resonance capacitor C1.
  • This circuit arrangement is for example in the Patent EP 0422 255 B1 disclosed.
  • the semiconductor switches T1, T2 are alternately activated and deactivated by means of the control device ST, so that the load circuit and the lamp LP are subjected to a high-frequency current whose frequencies are in the range of approximately 40 kHz and 150 kHz.
  • the ignition voltage required to ignite the gas discharge in the fluorescent lamp LP is provided by means of the resonance peaking method on the resonance capacitor CI.
  • the switching frequency of the semiconductor switches T1, T2 and thus also the frequency of the current in the load circuit is set to a value close to the resonance frequency of the resonance components L1, C1.
  • the load circuit formed as a resonant circuit is attenuated by the impedance of the now conductive discharge path between the electrodes E1, E2 of the fluorescent lamp LP.
  • the impedance of the discharge path of the fluorescent lamp LP and its power consumption are dependent on the frequency of the lamp LP flowing electricity.
  • the half-bridge current flowing through the resistor R2 is evaluated by means of two low-pass filters R3, C3 and R4, C4, since the half-bridge current flowing through the resistor R2 during a half-wave - namely with the switch T2 closed - with that through the fluorescent lamp LP flowing current is identical.
  • the first low-pass filter R3, C3 acting as an integrator forms at the capacitor C3 a voltage drop which is proportional to the power consumption of the fluorescent lamp LP and which is the actual value for a first control loop for controlling the brightness and regulating the power consumption of the fluorescent lamp. Integral controller IR is supplied.
  • This actual value is compared in the proportional-integral controller IR with a predefinable setpoint SW, which is the controller ST from the outside, for example, from a dimming potentiometer or other dimming device specified.
  • the setpoint SW represents the desired brightness level or power level of the fluorescent lamp LP.
  • the proportional-integral controller IR determines a first control value for controlling the switching frequency of the semiconductor switches T1, T2.
  • the first manipulated variable is stored in the 14-bit data register S1 and read out by the driver switch TR, which generates control signals for the base or gate electrode of the semiconductor switches T1, T2.
  • the first control loop is executed at intervals of 1 ms each.
  • the frequency dependence of the half-bridge current is qualitatively represented.
  • the fluorescent lamp has its highest brightness and the luminous flux is therefore 100% of its nominal luminous flux. If the frequency is increased, the half-bridge current and thus also the power consumption and the luminous flux of the fluorescent lamp decreases.
  • the half-bridge current shows an extremely strong frequency dependence, so that unstable operating states can occur in this range.
  • a second control loop is implemented by means of the second low-pass filter R4, C4, the differential controller DR, the data memory S2 and the data register S1, which is traversed much faster than the first control loop.
  • the low-pass filter R4, C4 changes in the half-bridge current flowing through the resistor R2 are detected at time intervals of 100 ⁇ s.
  • the differential controller DR performs at intervals of 100 microseconds a setpoint-actual value comparison, being used as the actual value of the current, from the low-pass filter R4, C4 evaluated half-bridge current and is used as the setpoint of the data memory S2 temporarily stored actual value of each immediately preceding time interval ,
  • a second setpoint value is generated by the differential controller DR, which is supplied to the 14-bit data register S1 and added to the first setpoint value.
  • the driver circuit TR determines signals for frequency control of the semiconductor switches T1, T2. By means of the second control loop, the half-bridge current and thus the power consumption and the brightness of the fluorescent lamp are stabilized to the desired value.
  • the differential controller DR can be deactivated outside this critical operating range. This happens because the actual value of the second control loop before the nominal actual value comparison with a Amplification factor K is multiplied, which is dependent on the selected brightness level, that is, from the target value SW of the first control loop.
  • the gain K can be reduced to zero.
  • Both controllers IR, DR are designed as algorithms of a program-controlled microprocessor, which is part of the control device ST.
  • the first C3, R3 and second low-pass filters C4, R4 are replaced by a respective digital filter, wherein the first digital filter, the function of the first low-pass filter C3, R3 and the second digital filter, the function of the second Low-pass filter C4, R4 takes over.
  • the digital filters are formed as part of the control device ST and in particular as part of the aforementioned, programmatically operating microprocessor. Both digital filters evaluate the current flowing through the bridge circuit, that is, the voltage drop across the resistor R2. Their filter properties are determined by the software implemented in the microprocessor. In all other details, this embodiment is consistent with the above-explained first embodiment.
