Definitions

  • the present invention relates to a circuit arrangement for operating a high pressure discharge lamp with egg ⁇ nem electronic ballast, which is designed readiness determine an AC feed signal for the high pressure discharge lamp, wherein the frequency of the AC feed signal is min ⁇ least 1 MHz. Moreover, it relates to a procedural ⁇ ren for operating a high pressure discharge lamp with egg ⁇ nem AC feed signal, wherein the frequency of the AC supply signal is at least 1 MHz.
  • High-pressure discharge lamps as used, for example, as video projection lamps, usually have two similar electrodes, which are generally of a rod-shaped design.
  • Such jumping arc approach affected insbeson ⁇ particular, the use of high intensity discharge lamps in optical devices, such as projection devices, BEA and microscope lighting, and may result in useless application.
  • the current pulse before the commutation leads to a brief increase in temperature at the current leading points of the arc at the electrodes, mainly the current anode.
  • material accumulation occurs, i. H.
  • the electrode metal tungsten from the gas cycle process is deposited with the tungsten halides on the electrodes, as well as a spike on the electrodes, which stabilizes the discharge and the approach of the arc very effectively.
  • the present invention is therefore the object of the above-mentioned circuit arrangement or the aforementioned method such that in the specified frequency range, ie in RF operation of the high-pressure discharge lamp, jumping of the approach of the arc is reliably prevented on the electrode tips.
  • the present invention is based on the finding that a very effective stabilization of the arc in high-frequency operation can be achieved when the AC feed signal is modulated in amplitude.
  • the Ursa ⁇ chen this are currently not yet fully understood, since in addition amplitude amplitudes and amplitude reductions bring about the success of the invention and to avoid flickering of discharge arcs in general, especially plasma arcs in Hochlichentla ⁇ tion lamps lead.
  • An indication for this is that a stabilizing peak formation similar to that which results in operation with the circuit arrangement presented in the aforementioned US Pat. No. 5,608,294 does not take place until after a few hours. In other words, this means that the actual explanation for the solution according to the invention is not to be found in the peak formation.
  • a stabilization is achieved which satisfies even the high optical requirements for projection lamps.
  • HF operation In contrast to LF operation, HF operation enables simple, even single-stage ballasts. This made light ⁇ compared to the current state of the art (low-frequency operation) greatly reduced and thus significantly cheaper ⁇ ballasts.
  • the amplitude modulation represents a pulse modulation. sondere acoustic resonances Re ⁇ achieved outside the range greater stabilization of the arc by a pulsed, periodically repeated amplitude modulation of the AC feed signal.
  • the pulse modulation has a repetition frequency of 100 Hz to 100 kHz, preferably from 100 Hz to 2 kHz.
  • the duty cycle of the pulse modulation is preferably between 1% and 50%, be ⁇ vorzugt between 3% and 20%. From the perspective of video projection applications, duty cycles have proven to be very advantageous in which the modulation pulses take only very short periods of time, in particular periods of time which are shorter than the image dark gap.
  • the amplitude modulation of the AC feed signal may be at a constant frequency, but may also be accompanied by a frequency change.
  • the changed frequency is in a range of - 50% to + 100%, preferably in a range of - 10% to + 10%, the frequency of the AC feed signal.
  • the pulse modulation can be characterized by an amplitude increase compared to the unmodulated AC feed signal. Particularly good results with regard to the stabilization of the arc have resulted in amplitude peaks between 20% and 1000%, preferably between 20% and 200%, of the amplitude of the unmodulated AC feed signal.
  • the Pulsmodula ⁇ tion can also be characterized by a reduction in amplitude compared to the unmodulated AC feed signal.
  • the amplitude reduction is between - 5% and - 90% of the unmodulated AC supply signal.
  • the pulse modulation can be characterized by a sequence of amplitude peaks, a sequence of amplitude decreases and a sequence of amplitude peaks and amplitude decreases, which alternate with each other.
  • the amplitude peaks and / or amplitude noise will always be positive amplitudes or always negative amplitudes or alternately positive and negative amplitudes or simultaneously in positive or negative amplitude of the unmodulated AC feed signal.
  • the sequence of an amplitude increase with an immediately following amplitude reduction or the reverse order has proved to be particularly advantageous.
  • the success according to the invention has been achieved in the case of a wide variety of pulse shapes, in particular in the case of rectangular, triangular, semi-sinusoidal, rectangular with exponential rise or sawtooth-shaped pulse shape.
  • the electronic ballast preferably comprises: an input terminal for turning close to an input voltage, an output terminal for providing an AC feed signal to the high ⁇ pressure discharge lamp and, disposed between the matterssan ⁇ circuit and the output terminal series ⁇ factory circuit of an inverter and a Lastnetz-, wherein the inverter an AC output lessons ⁇ output voltage with a predetermined frequency, a pre- provides a variable amplitude and a predeterminable duty cycle to the load network.
