Definitions
- the invention relates to a method for operating a high-pressure discharge lamp.
- the invention also relates to an operating device which carries out this method.
- the invention is based on a method for operating a high pressure discharge lamp according to the preamble of the main claim.
- HID lamps high-pressure discharge lamps
- a relatively low-frequency rectangular lamp ⁇ power supply as shown in Fig. 1, used with rapid commutation.
- This mode of operation applies in particular to the operation of
- the current commutation serves to prevent the one-sided electrode wear and must be accomplished with sufficiently fast polarity reversal, so that the lamp does not go out during commutation.
- the commutation time should typically be in the range
- the commutation frequency is generally chosen so that, on the one hand, the short-term discontinuities during the commutation process do not appear in the light as flickering and, on the other hand, the acoustic emissions from both ECG as well as from the hot lamp as possible not fall into the audio range.
- the commutation frequency should therefore be selected as far as possible in the range between 50Hz and 200Hz.
- the commutation frequency should not be placed over the audio listening range> 20 kHz, so that the operation of the lamp, the acoustic resonances of the arc, which are in common lamp geometries yes between 20kHz and 150kHz, not be arbitrarily excited.
- a resonant excitation of the arc would result in the masters ⁇ ten cases arc fluctuation and arc instabilities that can ultimately lead to extinction of the lamp or even destruction of the lamp.
- Burning position due to buoyancy forces in the hot lamp itself, is systematically deflected out of its axial center upwards and thus forms arcuate between the electrodes.
- Color segregation is understood to mean the uneven distribution of the filling components in the arc plasma in the lamp, which leads to different light parameters between the upper and the lower part of the lamp.
- the color segregation occurs in particular in the vertical lamp burning position.
- the simplest method for targeted excitation of a specific acoustic natural frequency in the lamp is not to operate the arc with the electronic control gear as usual in the low-frequency rectangular mode, but the arc already with an AC voltage or to operate an alternating current with the corresponding half frequency of the acoustic self-resonance.
- Fig. 2a One known mode of operation that leads to arc stabilization via the 2A excitation, which does not allow color segregation, would be the simple square wave operation as shown in Fig. 2a, with simple sequential direct drive, in which an operating frequency is briefly removed from the rectangular mode in the direct drive from eg 40 kHz is set, with which the excitation of a certain acoustic self-resonance, e.g. to set the 2A resonance.
- Fig. 2b shows a section of the direct drive with an operating frequency of 40 kHz.
- the segregation of the filling components can be prevented by the targeted excitation of a special acoustic self-resonance in the discharge arc of the lamp with longitudinal mode character (2L excitation), since this mode leads in lamp burner vessel to form cross-flow ⁇ cells that counteract the segregation of the filling components.
- 2L excitation longitudinal mode character
- the targeted excitation of the 2L mode in the lamp must be done by the electrical operating device.
- arc straightening Similar to colormixing, arc straightening also excites a specific acoustic self-resonance in the discharge arc (2A excitation), which, due to its modal characteristics, does not lead to the usual bow instabilities, but rather to increased stability of the arc Arc in the axial direction brings with it.
- the natural resonances in question are usually those with an azimuthal mode structure.
- the excitation can take place via a direct high-frequency operation (so-called direct drive), via an amplitude modulation to the low-frequency square-wave voltage or through a mixture of these operating modes.
- direct drive a direct high-frequency operation
- loading the high-frequency operation of a low-frequency right ⁇ wave voltage is combined for operating the gas discharge lamp agreed azimuthal resonance frequencies at the same time be ⁇ voted longitudinal resonance frequencies excited.
- the excitation can be done either by a direct drive with two different frequencies in two different ones
- a circuit arrangement for carrying out this method is known from WO2008 / 083852A1, the disclosure content of which is hereby incorporated by reference.

- Fig. 5b is a detail view of the amplitude modulated
- Fig. 5c is a detailed view of the Amplitudenmodulationsfre acid sequence of the lamp voltage for excitation of the longitudinal modes from FIG. 5a,
- FIG. 6a is a graph of the lamp operating voltage of a fourth embodiment of the method according to the invention with an arc straightening with sequentially alsmodulier ⁇ ter to the low-voltage high-frequency voltage for exciting the longitudinal and azimuthal modes,
- FIG. 6b shows a detailed view of the two sequential amplitude modulation frequencies of the lamp voltage for excitation of the azimuthal and longitudinal modes from FIG. 6a.
- the position of the azimuthal natural frequencies active for arc straightening depends on the one hand on the geometry of the lamp (length, aspect ratio) but also on the general operating parameters of the lamp, such as pressure, temperature,
- the azimuthal eigenmodes are in the range between 20 kHz to 150 kHz, typically around 80 kHz.
- the effective longitudinal natural frequencies are also dependent on the geometry of the lamp (length, aspect ratio) and also from the general operating parameters of the lamp, such as pressure, temperature, fill gas, charge components, power, etc.
- the longitudinal eigenmodes are in the range between 20 kHz to 60 kHz, typically about 26 kHz.
- the electronic operating device must operate the lamp exactly at half the operating frequency at 30 kHz in a sinusoidal manner. If you want to stimulate an azimuthal mode in the lamp at 80KHz, the electronic control gear must operate the lamp exactly sinusoidal at half the operating Wech ⁇ frequency at 40kHz.
- This supply current would have a singular frequency component at 30kHz or at 40kHz, and the corresponding power spectrum, ie the spectrum of the product of current and voltage would be a singular frequency line will have exactly in the double ⁇ th frequency, ie at 60 kHz or at 80kHz, with the then the corresponding acoustic mode is excited in the lamp.
- the disadvantage of the Direct-Drive is that it is ⁇ rig relatively Schwiering to control the excitation intensity of the desired acoustic eigenmode because the direct drive of Naturalmodula ⁇ tion degree always being 100% and the two degrees of freedom, the size of the sweep range, so the Frequency range, the is exceeded periodically or the Sweepwiederholfrequenz, can be varied only conditionally.
- the size of the sweep range can not be arbitrarily broadened, since usually in the immediate vicinity of the targeted and Bogenogenradrading active resonance more natural acoustic frequencies are that should not be taken gefof ⁇ fen, as this then disadvantageous when excited with their negative effects on the sheet stability would do.
- the sweep repetition rate or the sweep repetition frequency can generally not be lowered arbitrarily, since unavoidable power fluctuations occur during the
- the sweeping process can only be compensated accurately with high outlay, and these power fluctuations would be noticeable as fluctuation in the light, especially at frequencies ⁇ 50 Hz.
- the corresponding frequency component In low-frequency rectangular operation, the corresponding frequency component must be additively set as an amplitude modulation to the rectangular lamp supply for the electrical excitation of a special natural lamp frequency.
- the modulated frequency component coincides in magnitude with the value of the actual target natural frequency in the lamp, and the modulated frequency component appears directly in the power spectrum of the square wave signal.
- the frequency doubling as with the direct drive does not take place here.
- the modulated frequency component must also be at 26kHz.
- Self-resonance can be set clearly on the depth of the modulation or the degree of modulation, which would allow even an on ⁇ adjustment to individual lamps.
- the degree of modulation of the Amplitudenmodula ⁇ tion is for effective modulation between 5% and 30%, typically 10%.
- FIG. 3a shows a graph of the lamp operating voltage of a first embodiment of the method according to the invention with arc straightening with dual sequential direct drive in combination with a neutral square wave signal for excitation of the azimuthal and longitudinal modes.
- This mode of operation is the dual sequential direct drive in combination with a neutral rectangular signal in which two different time slices each two different operating frequencies are impressed, with which then two different acoustic Eigenreso ⁇ nanzen can be excited with adjustable strength wherein the basic operation of the lamp on the rectangular mode, as shown in Fig.l is done.
- the excitation of the 2nd azimuthal self-resonance for the purpose of arc straightening (the arc Staightenings), as shown in Fig. 3b, is carried out sequentially on the short-term operation of the lamp in the direct drive mode at 40kHz, via the setting of the temporal duty cycle of Rectangle mode and direct drive mode, the absolute excitation power for the acoustic self-resonance can be set.
- a modulation depth of 10% can be achieved with a direct drive time slice of lmsec.
- the excitation of the 2nd longitudinal mode resonance (2L resonance) 3c ge ⁇ shows for the purpose of Colormixings, as shown in Fig., Is performed sequentially over the short-term operation of the lamp in the direct drive mode at 13kHz, wherein terminating the temporal duty cycle Rectangle mode and direct drive mode, the absolute excitation power for the acoustic self-resonance can be set.
- a modulation depth of 12% can be realized with a direct-drive time slice of 1.2 ms.
- FIG. 4a shows a graph of the lamp operating voltage of a second embodiment of the method according to the invention with arc straightening with sequential direct drive for excitation of the azimuthal modes and high-frequency voltage modulated on the low-frequency voltage for excitation of the longitudinal modes.
- the excitation of the 2nd azimuthal self-resonance for the purpose of arc straightening (the arc Staightenings), as in Fig. 4b is shown sequentially on the short-term operation of the lamp in the direct drive mode at 40kHz, where the excitation strength for the acoustic self-resonance can be set by setting the temporal duty cycle of the rectangular mode and direct drive mode.
- a modulation depth of 10% can be achieved with a direct drive time slice of lmsec.
- the excitation of the 2nd longitudinal mode resonance (2L resonance) for the purpose of Colormixings as ge ⁇ shows in Fig. 4c, via which an imprint of a Amplitudenmodula ⁇ tion to the amplitudes of the rectangle.
- the AM modulation frequency is 26kHz.
- the adjustable AM modulation depth determines the excitation intensity for the 2L colormixing resonance.
- the amplitude modulation can optionally during the entire period, ie during the pure rectangular fashion phase and the direct-drive phase activated (see. The Ausstateun ⁇ gen to the third embodiment) or only during the pure rectangle phase be enabled and during considerablezeiti ⁇ be switched off Direct Drive phase.
- Fig. 4b shows a graph of the lamp voltage during the time slice in which the direct drive is active.
- Fig. 4c shows a graph of the lamp voltage during the time slice in which the lamp is operated with a modulated low frequency voltage.
- FIG. 5a shows a graph of the lamp operating voltage of the third embodiment of the method according to the invention with arc straightening sequential direct drive to excite the azimuthal modes and to the low frequency voltage and to the voltage of the direct drive modulated high frequency voltage to excite the longitudinal modes.
- amplitude modulation for color mixing is modulated not only on the low-frequency rectangle, but also on the high-frequency sinusoidal voltage for arc straightening.
- Fig. 5b shows the modulated sinusoidal voltage in the direct drive, which is modulated with an amplitude modulation at 26 kHz.
- FIG. 5 c shows a section of the rectangular voltage, which is likewise modulated with an amplitude modulation at 26 kHz.
- FIG. 6a shows a graph of the lamp operating voltage of a fourth embodiment of the method according to the invention with arc straightening with a high-frequency voltage modulated onto the low-frequency voltage for excitation of the longitudinal and azimuthal modes.
- This mode of operation would be in the rectangular mode of the dual sequential AM operation, in which the amplitude modulation is operated in two different time slices each with two different frequencies.
- the excitation intensity of the two targeted acoustic self-resonances can be adjusted via the corresponding associated AM depth.
- FIG. 6b shows a detailed view of the lamp voltage for exciting the azimuthal and longitudinal modes of FIG. 6a. The section was chosen so that the change between the two modes is visible.
