Definitions

  • the invention relates to a high-pressure mercury vapor discharge lamp with a bulb made of high-temperature-resistant material which contains electrodes made of tungsten and a filling which consists essentially of mercury, noble gas and halogen free in the operating state.
  • a super high pressure mercury vapor discharge lamp of this type known from DE-AS-14 89 417 has an elongated quartz glass bulb with a volume of 55 mm 3. This flask is filled with noble gas and 6.5 mg mercury; this corresponds to an amount of mercury of 0.12 mg / mm3.
  • the mercury vapor pressure should be about 120 ⁇ 105 Pa (120 bar).
  • the lamp has a power density of around 14.5 W / mm3.
  • Such lamps with mercury vapor pressures of about 120 ⁇ 105 Pa (120 bar) produce a high luminance, but essentially give off a typical mercury spectrum, which is superimposed on a continuous spectrum, with a low red component.
  • a super high-pressure mercury vapor discharge lamp with a capillary tube made of quartz glass is known, which is filled with mercury up to a quantity of 0.15 mg per cubic millimeter; this corresponds to a mercury vapor pressure of about 150 ⁇ 105 Pa (150 bar).
  • this lamp is also filled with at least one metal iodide.
  • the high electrode load on these lamps leads to tungsten evaporating from the electrodes and being deposited on the bulb wall. This leads to a blackening of the piston, which heats it up strongly, which, particularly at high mercury vapor pressures, can lead to an explosion of the piston.
  • the invention is therefore based on the object of creating a high-pressure mercury vapor discharge lamp of the type mentioned at the outset, which, in addition to a high luminance and good luminous efficiency, has improved color rendering and a longer service life.
  • This object is achieved in a high-pressure mercury vapor discharge lamp of the type mentioned at the outset according to the invention in that the amount of mercury is greater than 0.2 mg / mm 3, the mercury vapor pressure in operation is greater than 200 ⁇ 105 Pa (200 bar) and the wall load is greater than 1 W. / mm2 and that at least one of the halogens Cl, Br and I is present in an amount between 10 ⁇ 6 and 10 ⁇ 4 »mol / mm3.
  • the upper limit of the mercury vapor pressure depends on the strength of the piston material, but should be around 400 ⁇ 105 Pa (400 bar) in practice.
  • the amount of mercury is preferably between 0.2 and 0.35 mg / mm3 and the mercury vapor pressure is between 200 ⁇ 105 and 350 ⁇ 105 Pa (200 and 350 bar).
  • the mercury vapor discharge lamps according to the invention contain no metal halide, since a metal halide concentration so high would be required for a significant increase in the continuum portion of the radiation that the electrodes would be very quickly corroded due to the high tungsten transport rates.
  • Heavy-duty metal halide lamps e.g. in GB-PS-11 09 135 are therefore typically only lifetimes of a few hundred hours, while in the lamps according to the invention lifetimes of more than 5000 hours with almost constant luminous efficacy ( ⁇ ⁇ 2%) and almost completely constant color coordinates ( ⁇ x, ⁇ y ⁇ 0.005 during 5000 hours) could be achieved.
  • the high-pressure mercury vapor discharge lamp 1 according to FIG. 1 has an ellipsoidal lamp bulb 2 made of quartz glass. Cylindrical quartz parts 3 and 4 adjoin the piston ends, into which molybdenum foils 5 and 6 are melted in a vacuum-tight manner. The inner ends of the molybdenum foils 5 and 6 are connected to electrode pins 7 and 8 made of tungsten, which carry wraps 9 and 10 made of tungsten. The outer ends of the molybdenum foils 5 and 6 are connected to current supply wires 11 and 12 made of molybdenum.
  • Cylindrical lamp bulb according to FIG. 2 with 1.3 mm wall thickness without outer bulb The internal dimensions and operating data are:
  • Example 3 shows the light spectrum emitted by a lamp according to Example 2 as intensity I over the wavelength ⁇ . This shows that the continuum portion of the visible radiation is about 50%.
  • the lamps according to the invention Compared to comparable highly loaded metal halide lamps, the lamps according to the invention have a somewhat lower luminous efficiency and, when operated without a filter, also poorer color rendering properties, but are distinguished by extremely good constancy of the photometric data, an almost unchangeable luminous efficiency during the burning time and a very long service life. While a life span of several hundred hours is achieved with highly loaded metal halide lamps, the lamps according to the invention do not show any noteworthy changes even after a burning time of more than 5000 hours.
