Definitions

  • the invention relates to an electrode for a discharge lamp according to the preamble of patent claim 1 and a discharge lamp with at least one such electrode and to a production method for such an electrode.
  • the WO 2005/096334 describes a high-pressure discharge lamp with a discharge vessel made of quartz glass and two similar electrodes for generating a gas discharge in the interior of the discharge vessel.
  • the electrodes each consist of a metal pin, which has a wound by a coil section. This section of the two electrodes projects in each case into a sealed end of the discharge vessel and is embedded in the quartz glass of the discharge vessel.
  • the helices are equipped with fastening means which prevent slippage of the helices along the metal pins of the electrodes.
  • the DE 102004 057 906 A1 discloses a high-pressure discharge lamp having an electrode having a portion surrounded by a coil.
  • the electrode of the lamp according to the invention has a metal pin with a portion wrapped by a coil of metal wire, the metal wire of the coil being flattened.
  • a mechanical stress is built up in the metal wire, which is retained when winding the coil wire on the metal pin and causes a pressure of the coil to the metal pin.
  • This pressure creates a backlash-free and tight fitting to the metal pin coil. There are no further fasteners and manufacturing steps, such as welding required to prevent slippage of the coil on the metal pin.
  • the coil ensures that no cracks due to the different coefficients of thermal expansion of electrode material and discharge vessel material can form in the discharge vessel material, which would lead to premature failure of the lamp.
  • the coil is disposed at least on one end of the metal pin, the coil ensures the heat dissipation of this end or the ends of the metal pin.
  • the metal wire of the helix is preferably formed flattened over its entire length to ensure that all turns of the helix fit tightly and without play on the metal pin of the electrode.
  • the inner diameter of the helix or of the individual turns of the helix corresponds to the thickness of the metal pin section on which the helix is wound in order to enable a play-free seating of the helix on this section.
  • the metal wire of the helix is a tungsten wire or a molybdenum wire.
  • the electrode can be used in discharge lamps of very high thermal load, in particular in high-pressure discharge lamps, since tungsten and molybdenum have very high melting temperatures.
  • the molybdenum wire according to an embodiment in which the coil is disposed on a central portion of the metal pin, additionally has the advantage that a coil of molybdenum wire can act as a getter and protect the Molybdänfolieneinschmelzept the sealed ends of the discharge vessel of a high-pressure discharge lamp from corrosive substances in the discharge vessel can.
  • the metal pin of the electrode on which the aforesaid helix is wound is preferably a tungsten pin in order to be able to use the electrode in discharge lamps subjected to high thermal loads, in particular in high-pressure discharge lamps.
  • the thickness of the metal wire of the helix is preferably in the range of 10 microns to 1000 microns,.
  • the thickness of the metal pin of the electrode is preferably in the range of 0.10 millimeters to 2.00 millimeters. Such metal pin thicknesses are matched to the current carrying capacity of electrodes for high-pressure discharge lamps.
  • core diameter refers to the diameter of the pin on which the helical wire is wound.
  • a relatively large pitch factor is advantageous because due to the relatively large pitch factor, the turns of the coil are far apart, so that when sealing the discharge vessel of the discharge lamp, the softened discharge vessel material between adjacent turns of the coil can penetrate and wet the surface of the electrode.
  • this helix has a low heat capacity, so that the discharge vessel material cools more slowly when the helix flows around, thereby achieving a good seal.
  • the arranged at the ends of the helix first and last turn may have a lower pitch factor for manufacturing reasons.
  • slope factor and core factor of the helix are designed so that a good heat dissipation from the discharge end of the electrode is ensured.
  • the electrode according to the in FIGS. 1 to 4 Illustrated embodiments is particularly well suited for use in discharge lamps, which have a quartz glass existing discharge vessel.
  • these are high-pressure discharge lamps and preferably halogen-metal-vapor high-pressure discharge lamps with mercury-free filling.
  • the latter require due to their high starting current comparatively thick electrodes with high current carrying capacity, which must also consist of a high-temperature resistant metal, such as tungsten. Due to the very different thermal expansion coefficients tungsten and quartz glass and the comparatively thick electrodes, therefore, the above-described problem of premature lamp failure due to cracking in the discharge vessel in metal halide high-pressure discharge lamps with mercury-free filling is particularly acute.
  • the helically wrapped portion of the metal pin of the electrodes is embedded in the discharge vessel material of a sealed end of the discharge vessel to make electrical contact with an external power supply via a molybdenum foil fuse in the sealed end.
  • Lamp type prevents early lamp failure due to cracking in the discharge vessel.
  • Illustrated embodiments of the invention can be used in different types of high pressure discharge lamps.
  • the use of these electrodes is not limited to high-pressure discharge lamps with a discharge vessel made of quartz glass, but these electrodes can also be used in high-pressure discharge lamps with a discharge vessel made of translucent ceramic.
  • a corresponding example is shown schematically in FIG FIG. 5 shown.
  • the manufacturing method for the above-described electrode of a discharge lamp according to the invention is characterized in that the metal pin or a portion of the metal pin of the electrode is wrapped during a step of the manufacturing method according to the invention with a flattened metal wire to form a coil, the tight and without play on the metal pin or a portion of the metal pin of the electrode is arranged.
  • a mechanical stress is built up in the metal wire of the helix, which is retained during winding on the metal pin of the electrode and causes a pressure of the turns of the helix to the metal pin.
  • no further fastening means for fixing the helix to the metal pin of the electrode are necessary.
  • manufacturing steps such as welding the coil on the metal pin or pressing the metal pin in the coil account for.
  • manufacturing process also avoids local damage to the electrode and a change in the helical structure by welding the helix.
  • the manufacturing process for the electrode is simplified by the invention.
