  • the invention relates to a high pressure discharge lamp according to the preamble of Claim 1.
  • a metal halide high-pressure discharge lamp for use as a light source in a vehicle headlight.
  • Such lamps usually have an ionizable filling in addition to mercury and xenon Halides of the metals sodium and scandium and optionally also halides contains other metals.
  • the mercury is less used to generate light, but because of its high vapor pressure primarily to improve the electrical properties of these lamps, in particular to achieve a burning voltage in the range of 80 V to 110 V. Lately, such attempts have been attempted To design lamps without using the environmentally harmful mercury.
  • the European patent application EP 0 903 770 A2 describes mercury-free Metal halide high-pressure discharge lamps, their ionizable filling at least one easily evaporable metal halide serving as a voltage gradient generator and other metal halides used for light generation.
  • the metal halides serving as voltage gradient formers take over in essentially the functions of mercury in the mercury-free high-pressure discharge lamps.
  • Halides of metals are used as voltage gradient formers Al, Bi, Hf, In, Mg, Sc, Sn, Tl, Zr, Zn, Sb or Ga used. Mainly the generation of light Halides of the metals Na, Pr, Nd, Ce, La, Dy, Ho, Tl, Sc, Hf, Zr or Tm.
  • European published patent application EP 0 883 160 A1 discloses mercury-free Metal halide high-pressure discharge lamps, their ionizable filling Noble gas, a first metal halide used for light generation and a second contains metal halide which serves as a buffer gas and has a high vapor pressure.
  • the object of the invention is a mercury-free high-pressure discharge lamp To provide, which is suitable as a light source for a vehicle headlight.
  • the high-pressure discharge lamp according to the invention has a gas-tight seal Discharge vessel in which two electrodes and an ionizable filling for generation a gas discharge are arranged, wherein the ionizable filling Xenon and halides of the metals sodium, scandium, indium and zinc exist. It has been shown that by using only the aforementioned filling components a high-pressure discharge lamp with sufficiently good color rendering, Luminous efficacy and durability for use as a light source in one Vehicle headlights can be built. Those listed in the prior art Means for raising the burning voltage to that for lamps containing mercury Common values between 80 volts and 110 volts are not required. Instead the high-pressure discharge lamp according to the invention has an operating voltage of only 45 volts.
  • the halides are advantageously iodides or bromides and not fluorides, as the latter only work in conjunction with a discharge tube Ceramics can be used.
  • the iodides of the above are particularly preferred Metals, as they are chemically less aggressive than the bromides and mostly one have higher vapor pressure.
  • the iodides of the above are particularly suitable Metals also for high-pressure discharge lamps with a discharge vessel Quartz glass. They are not necessarily discharge vessels made of translucent ceramic such as polycrystalline aluminum oxide, sapphire or aluminum nitride required.
  • an ionizable filling which consists of the following components:
  • Xenon with a cold filling pressure that is the pressure at room temperature (22 ° C), from at least 9000 hPa, preferably even at least 11000 hPa and at most 13000 hPa, at least 0.15 mg and at most 0.30 mg sodium iodide, at least 0.10 mg and at most 0.25 mg of scandium iodide, at most 0.10 mg, preferably but not more than 0.05 mg zinc iodide and a maximum of 0.05 mg indium iodide.
  • the burning voltage of the lamp that is the voltage drop across the lamp in the quasi-stationary Lamp operation, that is, after ignition and stabilization the gas discharge in the discharge vessel, to a constant value, preferably to 45 volts, set.
  • Xenon also contributes significantly to increasing efficiency the generation of light in the gas discharge.
  • the cold filling pressure of the xenon should therefore be at least 9000 hPa, preferably even at least 11000 hPa to achieve a high luminous flux and thus a high luminous efficiency.
  • the discharge vessel would can also withstand a xenon cold filling pressure of more than 20,000 hPa, but at one Exceeding the xenon cold filling pressure of 13000 hPa both change Burning voltage of the lamp and the color temperature of the gas discharge generated light.
  • the proportion of scandium iodide would have to be increased. However, this could damage the quartz glass, which is preferably made of quartz glass Discharge vessel because scandium reacts chemically with quartz.
  • the operating voltage of the lamp the proportion is set to a predetermined value, preferably 45 volts of zinc iodide advantageously chosen accordingly.
  • the percentage of zinc iodide is advantageously less than or equal to 0.10 mg and preferably even less than or equal to 0.05 mg.
  • Y is the numerical value of the zinc iodide fraction in Milligrams [mg]
  • X the numerical value of the xenon cold filling pressure in hecto-Pascal [hPa] mean ( Figure 3).
  • For generating light in the high-pressure discharge lamps according to the invention serve, in addition to the filling components already mentioned also sodium iodide, scandium iodide and indium iodide.
  • the above Quantity ranges for these filling components are determined by the desired ones Color temperature, preferably 4000 K, and the desired color location by the Gas discharge generated light.
  • the addition of a comparatively small amount of indium iodide is required to emit white light according to ECE regulation R.99 produce.
  • the color location of the filling is according to the preferred embodiment within the trapezoid shown in FIG. 4, which is the color loci of light sources for vehicle headlights white light defined according to ECE regulation R.99. If indium iodide is not used a color temperature of 4000 K can also be achieved, but the The color locus of the light would lie outside the trapezoid shown in FIG. 4 and thus the lamp would no longer be suitable as a vehicle headlight lamp.
  • the molar ratio of sodium to scandium in the ionizable filling advantageously has a value between 3 and 6.
  • the electrodes of the high-pressure discharge lamps according to the invention advantageously have a thickness or a diameter in the range from 0.27 mm to 0.36 mm to be able to conduct a sufficiently high current.
  • the high-pressure discharge lamps according to the invention have a low burning voltage U in comparison to the prior art Power consumption, usually 35 watts, as with the ordinary mercury-containing ones
  • High-pressure discharge lamps corresponding to thicker electrodes the one have a correspondingly higher current carrying capacity.
  • the distance between the electrodes is advantageously less than 5 mm, so that the discharge arc by means of the optical systems in the vehicle headlights can be better mapped.
  • the preferred embodiment of the invention is a mercury-free metal halide high-pressure discharge lamp with an electrical power consumption of approximately 35 watts.
