Definitions

  • the present invention relates to devices and methods for operating a gas discharge lamp and relates in particular to lighting installations in which gas discharge lamps are operated by means of electronic ballasts.
  • gas discharge lamps and in particular of fluorescent tubes, is widely used in many industrial and commercial sectors because of the higher efficiency compared to the filament lamps and the broadly adjustable light characteristics through the choice of phosphor coating.

  • the power factor regulator usually requires a further switch element and an inductance, so that the component cost increases significantly. Furthermore, an efficiency of the power factor regulator of about 95% at most can be achieved with reasonable effort, so that the overall efficiency of the system consisting of power factor controller, electronic ballast and gas discharge lamp is reduced.
  • the boost converter used in the power factor controller operates in the switch mode and thus contributes to a further increase in the interference, so that a considerable effort to filter the interference and corresponding expensive metallic housing are necessary.
  • Document EP 0 782 245 A2 shows a three-phase bridge rectifier for driving an inverter circuit according to the features of the preamble of claim 1.
  • EMC electromagnetic compatibility
  • the invention is extremely advantageous, since there usually 3 Phase connection is available anyway and the direct use of the rectified polyphase voltage without power factor controller significantly increases the efficiency.
  • Different mains voltages in different countries USA, Japan 220V, Europe 380V outer conductor voltage
  • the high rectified voltage of about 560 to 600 V European is advantageous for the ignition of the gas discharge lamp.
  • a backup capacitor is provided on the output side of the multi-phase full wave rectifier.
  • the short voltage dips when switching the half-bridge can be substantially offset.
  • the capacitance of the backup capacitor can be chosen to be relatively small, since this does not have to smooth the ripple of the rectified DC voltage, but must support the voltage only during the switching operations that take place at the high operating frequency, the half-bridge.
  • the half-bridge can be dispensed with expensive, large-volume and trouble-prone electrolytic capacitors.
  • the device also has a precontrol which modulates the external control signal in the opposite sense to a ripple of the rectified polyphase voltage. In this way even the slight variations in lighting, if these should be disturbing for certain applications, are largely taxed out.

  • a method of controlling a lighting system comprising a polyphase AC voltage source, a polyphase full wave rectifier, an electronic ballast, and a gas discharge lamp or metal halide lamp.
  • the method comprises the steps of rectifying the polyphase AC voltage, supplying the rectified voltage to the electronic ballast, generating a control signal for adjusting the illuminance of the gas discharge lamp or metal halide lamp, and supplying the control ballast signal to the electronic ballast, the illuminance of the gas discharge lamp or metal halide lamp adjust, where the power factor is greater than or equal to 0.95.
  • the generation of the control signal is based on one or more of: the duration of the intended emission of the gas discharge lamp or metal halide lamp, the current illuminance of the gas discharge lamp, integrated illuminance over a predefined period of time, operating age of the gas discharge lamp, physical and / or biological effect the emitted radiation to a specified object, operating temperature of the gas discharge lamp and operating temperature of a certain area of the electronic ballast.
  • the generation of the control signal can take place application-specific by means of suitable parameters. For example, when using the lighting installation in a sunbed, the problem arises that the emitted radiation should occur only in a certain frequency range and with a certain intensity.
  • the emitted radiation can be monitored and a signal output from the sensors can be used as a parameter to generate the control signal.
  • a corresponding sensor output signal may, for example, indicate the exceeding of a maximum instantaneous radiation intensity and / or a maximum or desired integrated intensity.

  • FIG. 1a schematically shows a device 100 for activating a gas discharge lamp or metal vapor lamp 106, which in the embodiment shown here can be embodied, for example, as a fluorescent tube.
  • the apparatus 100 includes a three-way full wave rectifier 101 that rectifies a three-phase AC voltage R, S, T.
  • the voltage between two phases is about 380V, so that the output side voltage of the rectifier 101 is about 560 volts, with the residual ripple of the rectified voltage about 10%. Due to the six-pulse circuit of the rectifier 101, the ripple has six times the frequency of the input AC voltage.
  • a support capacitor 102 On the output side of the rectifier 101, a support capacitor 102 may be provided, the capacity of which may be very low, for example 0.1 ⁇ F to 1 ⁇ F, since the capacitor 102 does not have to smooth the ripple of the rectified voltage, but the voltage during the high-frequency switching operations should support.

  • other circuit elements for example, the preheating of the electrodes of the gas discharge lamp 106 or various protection devices to avoid overcurrents and overvoltages, not shown.
  • various circuit variants with respect to the switch device 104 are possible. Thus, instead of the half bridge, a full bridge, or a single switching element can be used as a (resonant) boost converter.
  • the AC voltage RST is rectified by means of the diodes in the rectifier 101, whereby standard rectifier bridges or on demand fast switching diodes with a short recovery time can be used. Due to the direct rectification of the three-phase alternating current, the rectified voltage has only a small ripple of about 10% to 12%, so that in contrast to conventional electronic ballasts, this voltage is directly usable without a regulation of the power factor by means of an additional power factor regulator is necessary.
  • the drive circuit 108 generates the gate drive signals for the transistors T 1 and T 2 at a frequency and / or duty corresponding to the control signal in response to an externally supplied or internally generated control signal.

  • a typical operating frequency is 20 to 60 kHz, and the slight variations in illuminance caused by the ripple of the rectified AC voltage are barely noticeable due to the sixfold frequency of the AC input voltage.
  • the capacitance of the backup capacitor 102 can advantageously be chosen such that the voltage remains approximately constant during the switching operations of the transistors T 1 and T 2 , so that values of 0.1 ⁇ F to 1 ⁇ F or preferably of 0.1 ⁇ F to 0.67 ⁇ F suffice.
  • the residual ripple can be compensated for by a corresponding feedforward control (not shown) by supplying the rectified AC voltage to the drive circuit 108, for example by means of a voltage divider, so that the illumination fluctuation caused by the residual ripple can be substantially compensated.
  • a support capacitor 102 can be provided with a large capacity to smooth the ripple on the bridge rectifier, in which case, however, would be dependent on the expected output current, a correspondingly large-sized electrolytic capacitor to use.
  • FIG. 1b shows an embodiment which is identical to the embodiment of FIG. 1a with regard to the control of the gas discharge lamp 106.
  • the same parts are therefore assigned the same reference numerals and the description of these components is omitted.
  • the coil 105 is connected in series with a coupling capacitor 120 having a capacitance C K , which is for example in the range between 50 and 200 nF.
  • the resonant capacitance C K in this embodiment is out of the structure for the Device 100 is provided directly on the gas discharge lamp 106.

  • This embodiment requires only two leads to the gas discharge lamp 106, while still monitoring the lamp filament and a corresponding lamp monitoring is possible. In the embodiment, the corresponding leads (four terminals in total per discharge lamp) are not shown for the sake of simplicity.
  • the resonant capacitor 107 and optionally the resistors 121 may be housed in the starter housing. Thus, existing light systems can be used with the present invention.
  • a plurality of discharge lamps 107 may each be driven with an associated resonance capacitor in the starter housing, in which case only one common ground line and only one supply line from a corresponding half bridge 104 are required.
  • the three-phase full-wave rectifier 101 and the capacitor with optionally additional filter elements is accommodated on a separate board from which a plurality of half-bridge circuits 104, which can be arranged on one or more boards, are supplied.
  • a device 200 for driving a plurality of gas discharge lamps or metal halide lamps 206 includes a rectifier 201, which in turn is a three-phase full wave rectifier, optionally a back-up capacitor 202 on the output side of the rectifier 201 and a plurality of electronic ballasts 204 with corresponding control inputs 206 includes. Due to the omission of the conventional lighting controls necessary power factor regulators, several electronic ballasts can be arranged in a compact manner on a single electronic board. By avoiding the additional, heat-generating power factor controller thus relatively large power can be controlled by relatively compact drive units. Furthermore, instead of or in addition, an EMC filter can be provided.

  • a rectifier 313 is provided with an output capacitor 314.
  • F R 1 / ( 2 ⁇ L R C R )
  • the transformer 310 merely serves as a current source which has a voltage which corresponds to the back-transformed output voltage at the capacitor 314 and thus from the voltage at the gas discharge lamp 306.
  • the winding ratio of the transformer 310 is selected such that at rated operation approximately half the bridge voltage is established at the primary side of the transformer 310.
  • a corresponding behavior results when switching on the lower transistor, whereby the capacitor 307 is discharged by the sinusoidal resonant circuit current and energy is transmitted to the gas discharge lamp 306.
  • the lower transistor can then also be switched off without losses. Due to this arrangement, very high switching frequencies can be achieved due to the significantly reduced switching losses, so that the resonance frequency determining elements can be very small and therefore cost-effective.
  • the leakage inductance of the transistor 310 may be used as the inductance L R , so that no additional coil 305 is necessary.
  • the energy transfer to the gas discharge lamp 306 can be easily controlled by changing the switching frequency of the bridge 304. Due to the reduced switching losses results in a significantly improved EMC behavior, so that under certain circumstances, no or only a small low-cost EMC filter is necessary. By this arrangement, switching frequencies in the range of 20 to 1000 kHz can be achieved with high efficiency.
