Definitions

  • the invention relates to a method and a device for operating a high-pressure discharge lamp, in particular a high-pressure mercury lamp, a high-pressure metal lamp or a high-pressure sodium lamp, in which the direct current power derived from a voltage source is fed to an inverter which feeds the high-pressure discharge lamp in particular via a current limiting choke.
  • the choice of the operating frequency for ballasts of high-pressure discharge lamps is of considerable importance, since resonance effects due to longitudinal resonances occur within the tubular lamp body in lamps of this type.
  • the resonance frequencies depend not only on the type of gas used and the average gas temperature, but also on the burner geometry. Therefore, the resonance spectra for high-pressure discharge lamps of different types are different. However, resonance changes can also occur within a series of lamps of the same type.
  • the operating frequency of the inverter In order to achieve stable lamp operation, the operating frequency of the inverter must be shifted to a range in which no resonances occur. This has the disadvantage that only a ballast specially matched to this can be used for a particular lamp. If the operating frequency changes out of the permissible frequency window, instabilities occur due to the resonance phenomena.
  • the object of the invention is to further develop a method or a device of the type mentioned at the outset such that, on the one hand, high-pressure discharge lamps with a higher output, for example in the range from 70-2000 watts, can be supplied and, on the other hand, the disadvantages described above be avoided due to the resonance effects.
  • the inverter operating at an operating frequency in the range from 10 kHz to 100 kHz is operated with an output power that is periodically modulated by the nominal power value, the modulation frequency being in the range above 50 Hz and below Operating frequency of the inverter is.
  • this object is achieved in that means are assigned to the electronic inverter operating at an operating frequency of 10 kHz to 100 kHz for modulating its output power delivered to the high-pressure discharge lamp with a modulation frequency in the range between 50 Hz and below the operating frequency.
  • the invention is characterized in that the output power of the ballast, which is delivered to the high-pressure discharge lamp, is modulated so that a resonance build-up is avoided in principle.
  • the output power of the ballast which is delivered to the high-pressure discharge lamp
  • it is not the inverter frequency that is modulated within a previously defined frequency band, but rather the output power, whose mean value corresponds to the nominal value.
  • the "pumped" output power that is to say the constantly varying instantaneous power, means that no energy absorption at the resonance points can result in a build-up.
  • the modulation frequency can be varied over a wide range, the lower limit being determined only by the fact that flicker operation of the lamp which is visible to the eye must be avoided.
  • the modulation frequency is only upwards due to the operating frequency of the inverter limited, which is between 10 kHz and 100 kHz.
  • the ballast can now be used universally, regardless of the type of lamp and without exposing itself to the risk that, as in the prior art, on the one hand and inadequate adaptation of ballast and discharge lamp on the other hand, instabilities can occur.
  • the solution according to the invention can not only replace a conventional ballast but also has the advantage that the lighting comfort is increased since there is no flickering.
  • the device according to the invention is lighter in weight and can optionally be supplied with direct voltage (for example battery systems, solar plants) or with a rectifier with alternating current mains voltage.
  • no compensation capacitors are required as with conventional ballasts.
  • the output power can be modulated by driving the inverter at its control input with a variable frequency.
  • the lamp current at higher frequencies is periodically varied in accordance with the frequency swing due to the constant inverter supply voltage and the constant inductance.
  • the output power is modulated in that the inductance is replaced by a voltage-variable inductance in the form of a transducer, so that the corresponding modulation is effected at constant operating frequency and constant supply voltage of the inverter due to the variable inductance.
  • a third variant provides that the supply voltage at the input of the inverter is varied with a constant inductance and constant operating frequency of the inverter.
  • Another advantage of the invention is seen in the fact that the lamp power can now be dimmed in a simple manner.
  • further means are provided for varying the nominal value of the output power delivered to the high-pressure discharge lamp.
  • the modulation conditions described above are maintained so that the advantages as described above are retained. Only the nominal power fed into the lamp changes, so that the brightness is varied accordingly.
  • the output power is preferably modulated such that the stroke of the output power delivered to the high-pressure lamp is between the value zero and twice the nominal power, based on a fast ratio of 1: 1.
  • the definition of the duty cycle is variable, whereby the light quality suffers from flickering if the duty cycle is too large (e.g.> 10: 1).
  • the first exemplary embodiment of the invention shown in FIG. 1 shows a high-pressure discharge lamp 1 to be supplied, which can be a customary high-pressure mercury lamp, a high-pressure metal lamp or a high-pressure sodium lamp.
  • a rectifier 4 which is connected to a network 10, is connected to the direct current input of the inverter 3.
  • a frequency adjustment device 9 acts on the control input of the inverter 3.
  • the operating frequency of the inverter is typically between 10 and 100 kHz.
  • the operating frequency of the inverter 3 is now modulated via the frequency adjustment device 9 in such a way that the time profile of the lamp current I L fed into the high-pressure discharge lamp is shown in FIG. 4c.
  • the frequency swing of the frequency adjustment device 9 is adapted in this example so that the output power P varies by the nominal value (100%) fluctuating between the value 0 and 200%. On average, the power delivered to the lamp corresponds to the nominal power.
  • the frequency adjustment device 9 consists of a voltage-frequency converter 9a, a control amplifier 9b and a modulation amplifier 9c.
  • FIG. 4a shows the solution used in the prior art, which consists in applying a constant power to the high-pressure discharge lamp by generating a lamp current I L , which changes over time in a sinusoidal manner, by the inverter.
  • the frequency of the lamp current I L is adapted in accordance with the previously determined resonance conditions of the respective high-pressure discharge lamp.
  • Fig. 2 shows a variant of the embodiment shown in Fig. 1, which differs in that the inverter is now operated at a constant operating frequency and instead the inductor 7a in the output circuit of the inverter, which is designed as a transducer, is modulated.
  • the modulation is carried out by means of an inductance adjusting device 7, which emits a time-varying output voltage and consists of a control amplifier 7b and a modulation generator 7c.
  • the time course of the lamp current IL that occurs is shown in FIG. 4d.
  • the time profile of the output power determined by the envelope of the lamp current corresponds to that as shown in FIG. 4b.
  • the exemplary embodiment of the invention shown in FIG. 3 shows that the voltage present at the input of the inverter 3 is varied by means of a voltage adjusting device 6 such that the time profile of the lamp current IL shown in FIG. 4e results.
  • the time profiles of FIGS. 4d and 4e are identical.
  • the voltage adjustment device 6 consists of a modulation generator 6c, a control amplifier 6b and a voltage converter 6a.
  • the nominal value of the output power of the inverter 3 can be influenced by another switching means, without otherwise changing the described modulation conditions.
  • This measure allows the nominal value of the output power fed into the high-pressure discharge lamp to be varied, which enables the lamp to be dimmed.
  • the setpoint Via the current measuring device 2 and a control amplifier 6b, 7b or 9b, the setpoint is compared with the actual value and corrected. It is possible to dim the illuminant down to 25% of the nominal luminous flux, which can result in a maximum energy saving of 65%.
  • the solution according to the invention results in loss reductions of approximately 20% and increased light yields of approximately 10%.
