Definitions

  • the invention relates to a metal halide high-pressure discharge lamp according to the preamble of claim 1. It goes in particular from EP 0 702 394 A2.
  • Such lamps are characterized, among other things, by good to very good color rendering (R a ⁇ 80) and color temperatures in the range between approx. 4000 K and 7000 K. These values are achieved with light yields of typically more than 70 lm / W. These lamps are therefore suitable for general lighting as well as for special lighting purposes, e.g. projection technology, effect and stage lighting as well as for photo, film and television recordings.
  • the electrical power consumption is between approx. 35 W and 5000 W. Typical power levels for general lighting are 150 W and 400 W. For special lighting, such as video projection, higher wattages are usually required, typically 575 W and more.
  • EP 0 702 394 A2 describes a high pressure metal halide discharge lamp disclosed with an ionizable filling consisting of inert gas, mercury, Halogen, the elements thallium (Tl), cesium (Cs) and hafnium (Hf) for the formation of halides, with Hf completely or only partially Zircon (Zr) can be replaced, as well as the rare earth metals (SE) dysprosium (Dy) and / or Gadolinium (Gd).
  • an ionizable filling consisting of inert gas, mercury, Halogen, the elements thallium (Tl), cesium (Cs) and hafnium (Hf) for the formation of halides, with Hf completely or only partially Zircon (Zr) can be replaced, as well as the rare earth metals (SE) dysprosium (Dy) and / or Gadolinium (Gd).
  • Another aspect is the increase in luminous flux and in particular the Luminance.
  • the basic idea of the invention is to specifically fill the yttrium (Y) to add. It has been shown that this measure can reduce the tendency to devitrification.
  • Y yttrium
  • the addition of yttrium opens up the possibility of the filling quantity to reduce cesium, even to cesium as a filling component to do without entirely. This is particularly advantageous for projection lamps Aspect of the invention significant. Will the amount of cesium in the filling reduced, the luminous flux increases. On the other hand the discharge arc is also increasingly contracting. Consequently, the crucial for the projection technology luminance of the discharge arc even disproportionately compared to the increase in luminous flux. In front With this in mind, the big advantage is obvious due to the addition an appropriate filling amount of yttrium reduce the filling amount of cesium, to be able to completely do without cesium.
  • Cesium Due to the reduction of the luminous flux through the filling component Cesium is desirable to reduce the amount of cesium itself. However, this measure inevitably led to the state of the art to a rapid clear devitrification of the discharge vessel and was consequently not practical so far. Only through the addition according to the invention of yttrium is even possible, even with highly loaded metal halide discharge lamps without reducing the cesium content at the same time unacceptably increase the devitrification.
  • the ionizable filling of the discharge vessel also contains the following further elements for the formation of corresponding halides: thallium (Tl), hafnium (Hf), where the Hf can be replaced in whole or in part by zirconium (Zr) and the two or one of the two rare earth metals (SE) dysprosium (Dy) and / or gadolinium (Gd).
  • the filling also contains at least one inert gas, mercury (Hg) and at least one halogen. Iodine (I) and / or bromine (Br) are preferably used as halogens for the formation of the halides.
  • the inert gas for example argon (Ar) with a typical filling pressure in the order of up to approx. 40 kPa, is used to ignite the discharge.
  • the desired operating voltage is set by Hg. Typical amounts for Hg are in the range between approx. 10 mg and 30 mg per cm 3 of vessel volume for burning voltages between 50 V and 100 V.
  • the molar fill quantities of Tl, Dy and optionally Gd are typically up to 15 ⁇ mol, up to 30 ⁇ mol or up to 0.6 ⁇ mol per cm 3 of the vessel volume.
  • the molar amount of Hf and / or Zr is in the range between 0.005 ⁇ mol and 35 ⁇ mol, preferably in the range between 0.05 ⁇ mol and 5 ⁇ mol per cm 3 of the volume of the discharge vessel.
  • the filling quantity of the optional C is up to 30 ⁇ mol per cm 3 of the vessel volume.
  • Another advantage of the invention is the possibility, depending on the requirement to the lamp, the effect of yttrium on the one hand for a net reduction the tendency to devitrify with otherwise unchanged lighting properties to use.
  • the luminous flux can also be or increase the luminance with an otherwise unchanged tendency to devitrification. It is also possible to take a middle course.
  • part of the amount of rare earth metal for example dysprosium, which is customary without yttrium, is replaced by yttrium in molar equivalent.
  • Typical molar ratio between yttrium (Y) and the rare earth metal (s) (SE) are in the range 0.5 ⁇ Y / SE ⁇ 2.
  • Preferably 50% of the amount of the rare earth metal or the rare earth metals by yttrium is molar equivalent replaced.
  • the molar ratio between yttrium and the rare earth metal (s), for example dysprosium is therefore preferably one.
  • the usual amount without yttrium is added of the cesium reduced so far that the devitrification tendency compared to the Filling without yttrium remains unchanged.
  • the amount can be of the cesium disproportionately compared to the amount of yttrium added to reduce.
  • 50% of the usual amount for the has proven itself Rare earth metal to be replaced by yttrium and the previous one Halve the usual amount of cesium.
  • the discharge vessel is preferably operated within an outer bulb which is evacuated for particularly good color rendering.
  • the outer bulb contains a gas filling, for example up to 70 kPa nitrogen (N 2 ) or up to 40 kPa carbon dioxide (CO 2 ), although the color rendering is somewhat reduced.
  • a 575 W lamp 1 for projection purposes is shown schematically in the figure. It consists of a two-sided sealed discharge vessel 2 Quartz glass that evacuated from a cylindrical, one-sided base Outer bulb 3 is enclosed. One end of the outer bulb 3 has a rounded crest 17, whereas the other end one Has pinch seal and cemented into a socket 19 (type G22) is.
  • the electrodes 4, 5 opposite each other at a distance of 4 mm are melted gas-tight into the discharge vessel 2 by means of foils 6, 7 made of molybdenum.
  • the power leads 8,9 are each with the first ends two solid lead wires 20, 21 connected.
  • the second ends of the Lead wires 20, 21 are squeezed into the base of the outer bulb 3, whereby the discharge vessel 2 is axially fixed in the interior of the outer bulb 3 is.
  • Power leads are the lead wires 20, 21 with the electrical Connections 24, 25 of the socket 19 connected.
  • One in the base 19 between the terminals 24, 25 arranged mica plate 26 is used for electrical Insulation.
  • the filling contains 60 mg Hg and 22 kPa Ar as the base gas. Furthermore contains the discharge vessel 2 listed in Table 1 below Filling components in the quantities specified there in mass units. Table 2 shows the molar amounts calculated therefrom and the corresponding ones values related to the volume of the discharge vessel.
  • the electrode spacing and the volume of the discharge vessel are 4 mm and approx. 3.5 cm 3, respectively.
  • the specific arc power and the burning voltage are approx. 144 W per mm arc length or 62 V. Table 3 shows the lighting values achieved.
