Definitions

  • the invention relates to an electrode for a discharge lamp according to the preamble of patent claim 1 and to a discharge lamp with such electrodes.
  • Such an electrode and a discharge lamp with such an electrode are in US 4,700,107 discloses a high pressure discharge lamp with electrodes made of tungsten sheet.
  • the publication WO 03/060947 A2 describes a two-part electrode with a cylindrical shaft and a cylindrical head, wherein the shaft and the head of the electrode have different diameters or / and consist of different materials. This electrode is used in a high pressure discharge lamp for vehicle headlights.
  • the EP 0 892 423 A2 describes a short-arc discharge lamp and a manufacturing method for such a discharge lamp, in which a precise distance between the electrodes is adjustable. In this lamp, the electrode ends welded to the Ho foils are flattened.
  • the DE 37 16 485 C1 discloses a xenon short-arc discharge lamp with a quartz glass lamp bulb into which protrude two rod-shaped electrodes whose pitch is smaller than the diameter of the shaft of the cathode.
  • the cathode is provided with a conical, obtuse-angled tip. Again, the electrode ends welded to the Ho foils are flattened.
  • the JP-A 05-074420 discloses a discharge lamp with electrodes whose shank is formed flat.
  • the EP 0 383 108 A1 discloses a high pressure discharge lamp for AC operation with electrodes whose tip is shaped so that a first truncated cone tapers to a second truncated cone and which are ground to the respective fusion on two opposite sides.
  • the object of the invention to provide an improved electrode for Entladunsslampen.
  • the electrode should have a high rigidity.
  • the electrode according to the invention has an elongated shaft and a head which is arranged at one end of the shaft, wherein according to the invention the shaft is flattened so that its dimensions transverse to its longitudinal extent are at most as large as the corresponding transverse dimensions of the head.
  • the flattened shaft is better weldable with other metal parts, especially with molybdenum fusing films because there is a larger surface area in the area of the flattening is available for the welded joint.
  • the shaft has due to the aforementioned dimensions per unit length less mass than the head and thus a correspondingly lower heat capacity, so that only a comparatively small amount of energy in the form of heat via the shaft from the discharge is derived from the electrode of the invention.
  • the electrode according to the invention is flattened in an advantageous manner only on one side or on two opposite sides in order to simplify their production.
  • the flattening of the electrode in the region of the shank is carried out by machining material, preferably by means of milling or grinding or by evaporation of material, preferably by means of laser.
  • These methods have the advantage that the electrode according to the invention can also be formed in one piece in the region of the shaft and head, and thus, in particular, no welding between shaft and head is required.
  • the electrode according to the invention has improved mechanical stability compared to a multi-part electrode.
  • the transition from the head to the shaft of the electrode according to the invention is made as moderate as possible. According to the invention the transition is carried out by means of a radius whose value is in a range of 0.3 mm to 0.5 mm, see also the representation of the preferred embodiments according to the FIGS. 1 and 4 ,
  • the electrode according to the invention is preferably used as a gas discharge electrode for discharge lamps, in particular high-pressure discharge lamps with a discharge vessel made of quartz glass, which is provided with Molybdänfolienabdichtitch.

  • Such electrodes are suitable for use in metal halide high-pressure discharge lamps for motor vehicle headlights using a comparatively low power consumption of about 35 watts.
  • the electrode according to the invention consists of tungsten, a tungsten alloy or tungsten doped with dopants in order to be able to withstand the high temperatures of a gas discharge in a high-pressure discharge lamp.
  • the electrode according to the invention is preferably designed as a pin electrode.
  • the head of the electrode may be provided with a helix to increase the heat capacity of the head.
  • the entire shaft or portion of the shaft of the electrode of the invention may be coated with ruthenium to reduce the risk of cracking or cracking in the region of the discharge vessel in which the shaft of the electrode is closely embedded in the discharge vessel material.
  • FIGS. 1 to 6 schematically illustrated electrodes according to the preferred embodiments of the invention are suitable for use in the in FIG. 7 schematically illustrated metal halide high pressure discharge lamp provided.
  • the electrode 11 according to the first embodiment of the invention is formed as a one-piece pin and is made of tungsten, which may optionally have small amounts of the usual dopants, which are either advantageous for the processing of tungsten into rods, or, as in the case of, for example, thorium oxide, which improves the ignitability of the high pressure discharge lamp.

  • the transverse dimension of the shaft 11a parallel to the molybdenum foil 103 is 0.35 mm, thus coinciding with the diameter of the head 11b.
  • a tungsten rod is used whose transverse dimension in the region of the shaft 11a is adjusted to the desired value by two-sided mechanical material removal, preferably by means of milling or grinding.
  • the electrode 11 in the region of the shaft 11 a has an oval or rectangular cross-section.
  • the surfaces of the shank 11 a resulting from the flattening are particularly well suited for welding to the molybdenum foil 103.
  • a simplification of the production process of the electrodes according to the invention can be achieved by flattening the electrode in the region of the shank only on one side instead of two sides, as in the second embodiment of the invention and in FIGS FIGS. 4 and 5
  • the electrode 11 'according to the second embodiment is also made of tungsten and has a total length of 7.5 mm.
  • Its circular cylindrical head 11b ' has a diameter of 0.35 mm and a length of 1.0 mm.
