Definitions
- the invention relates to a method for operating a high-pressure discharge lamp according to the preamble of claim 1.
- a method of operating a high pressure discharge lamp by means of a bipolar Supply current is for example on pages 217 and 218 in the book "Operating Devices and Circuits for Electric Lamps" by C.H. Storm and E. Klein, Siemens AG, 6th revised edition 1992 described.
- This passage discloses the operation of a high pressure discharge lamp with a bipolar supply current, which has a substantially rectangular course over time.
- High pressure discharge lamps require a for their proper operation defined energetic household. If your energy balance is disturbed, then it happens Changes in the performance of the high pressure discharge lamp, for example to shorten the lamp life due to electrode erosion or Flicker caused by an undefined discharge arc approach.
- the high pressure discharge lamp with a bipolar supply current the zero crossing of the supply current in its polarity change a critical Operating phase of the lamp.
- high-pressure discharge lamps with comparatively thick electrodes which have a high thermal conductivity, such as in mercury-free metal halide high pressure discharge lamps, causes the increased heat transfer during the zero crossing of the supply current a correspondingly greater cooling of the lamp electrodes.
- the power fed into the high pressure discharge lamp may increase insufficient heating of the lamp electrodes before the polarity change lead the supply current. Accordingly, the lamp electrodes a reduced emissivity and that available after the polarity change Stress over the entire system, that is above the discharge arc and the Electrodes, is not enough to maintain the corresponding current flow as soon as possible. At the high pressure discharge lamp can be therefore, observe a flicker of the discharge arc. This applies in particular to heavily aged lamps.
- the method according to the invention for operating a high-pressure discharge lamp having a bipolar supply current and a predetermined electrical power is characterized in that an additional electrical power is supplied to the high-pressure discharge lamp at periodically recurring time intervals immediately after the zero crossing of the supply current, the time-averaged total power corresponds to the predetermined electrical power.
- the periodically recurring time intervals during which the additional electric power for the high-pressure discharge lamp is provided are arranged in time to the polarity change of the supply current of the high-pressure discharge lamp.
- these time intervals are arranged not only immediately after the polarity change but additionally also immediately before the polarity change or the zero crossing of the supply current.
- the additional power supply before the polarity change of the supply current allows a correspondingly stronger system heating to account for the cooling of the lamp electrodes during the zero crossing of the supply current and to counteract the resulting disadvantages listed above.
- the decisive additional power supply after the polarity change of the supply current is used for the fastest possible heating of the cooled lamp electrodes by the operation of the so-called electrode drop voltage and an associated higher power consumption.
- the duration of the periodically recurring time intervals for the additional power supply is preferably in each case 1 percent to 40 percent of a half-period duration of the supply current.
- the instantaneous value of the additional electrical power impressed during the periodically recurring time intervals of the high-pressure discharge lamp is preferably in the range from 1 percent to 300 percent of the value of the predetermined electrical power.
- the operating method according to the invention also enables dimming, that is, a brightness control of the high pressure discharge lamp. So can for the dimming operation the time-averaged overall performance of the high pressure discharge lamp be set a value which is lower than the rated power of the high pressure discharge lamp.
- the operating method according to the invention is based on a heavily aged mercury-free metal halide high pressure discharge lamp described for use in the headlight of a motor vehicle is provided, and has a rated power of 35 watts.
- This lamp has a Discharge vessel made of quartz glass with therein ionizable filling and arranged therein electrodes for generating a light emitting gas discharge.
- the ionizable filling contains xenon as well as halogen compounds of the metals Sodium, scandium, zinc and indium.
- This mercury-free metal halide high-pressure discharge lamp is by means of a control gear, the underlying circuitry on the Pages of the above-cited book is described, with a bipolar supply current fed, the time course is substantially rectangular.
- the frequency this rectangular bipolar supply current of the lamp as well as their in phase rectangular bipolar supply voltage is approx. 250 hertz.
- the timing of the supply current and the supply voltage as well as the instantaneous electrical power The lamp is shown in its usual units of amperes, volts and watts.
- the Timeline is scaled in units of milliseconds.
- the duration of a half-period the supply current and the supply voltage is 2 milliseconds each.
- the supply current is for the most part a positive or negative half-cycle about 0.5 amps or - 0.5 amperes.
- Only immediately before and after the polarity change of the supply current and the supply voltage take the significantly higher amounts, so that meanwhile an increased Power entry is made in the lamp.
- the duration of the increased power entry is 11 before and after the polarity change of the supply current Percent of a half period of the supply current, that is about 0.22 milliseconds.
- the instantaneous electrical power consumption of the lamp has during the largest Part of the positive and negative half periods of the supply current one almost constant value of about 30 watts.
- the supply current is the lamp during a time interval of each 0.22 milliseconds impressed an electrical power of about 95 watts and immediately after each polarity change of the supply current of the lamp during a time interval of also 0.22 milliseconds each an electric Power of about 80 watts impressed.
- the over the entire period or over a period of the supply current averaged power consumption of Lamp is about 35 watts.
