Definitions

  • the invention relates to a method for producing a discharge lamp with a discharge vessel filled with a discharge medium and with one running in the discharge vessel at a distance from the vessel walls Electrode, a pump stem in the manufacture of the discharge vessel is attached to the discharge vessel through which the discharge vessel evacuated and / or filled with the discharge medium and which is then closed.
  • a special type of discharge lamp are discharge lamps with dielectric disabled discharge.
  • the electrode and / or one counter electrode or several counter electrodes by at least one Dielectric separated from the discharge inside the discharge vessel.
  • the invention is not exclusively, but preferably, based on such discharge lamps for dielectrically impeded discharges.
  • one of the two electrodes forms permanently the anode and the other electrode the cathode. It is enough separating the anode from the discharge by the dielectric.
  • the vessel wall can also serve as a dielectric. In this case there is only the cathode in the discharge vessel, whereas the Anode or the anodes are applied to the outside of the vessel wall. This can be e.g. B. are strips of a gold or platinum paste, which are printed directly on the vessel wall.
  • the two electrodes are not against each other excellent and both shielded by a dielectric.
  • the corresponding voltage change sometimes forms the one electrode and times the other electrode the anode.
  • the discharge lamps are preferred with an in principle unlimited sequence of extremely short ones Voltage pulses fed with a high repetition frequency. Please refer to this on the W094 / 23442.
  • a pump stem in the form of a tube formed, which has one end through a wall of the discharge vessel protrudes into the discharge vessel.
  • the bracket can be designed so that it is a elongated, extending in the main direction of extension of the electrode Has support element which the electrode on at least a portion supports, the support element and the electrode being coaxial or aligned parallel to each other.
  • the electrode can be any one Have shape.
  • Have shape For example, vertical stripes, Waveform, for example in sinusoidal form, zigzag electrodes, one Act helix or the like.
  • the electrode can be in the form of a correspondingly structured conductive Coating, for example made of gold or platinum paste, on the holder or an element of the holder can be applied. So z. B. on this Way a helical inner electrode on one in the direction of extension the electrode extending support rod or support tube can be applied. Strips, waves or zigzag electrodes can applied for example on an elongated, plate-shaped support element his.
  • a in the support tube along the longitudinal extent or several openings are introduced through the pipe wall, which are located inside the discharge vessel. Through these openings is a better and more effective pumping or filling of the discharge vessel possible.
  • this advantageously has a transverse to the longitudinal direction of the support element extending holding projection or a holding recess on.
  • the holding projection can be corresponding Knobs, noses, thorns, etc. act in the holding recess by one Groove or the like.
  • knobs or lugs for example Wire coil, which runs around a support tube or a support rod, very much well secured against longitudinal displacement.
