Definitions

  • This invention relates to gas-filled electric discharge tubes. More particularly, the invention relates to elongated positive column gas-filled electric discharge tubes comprising an auxiliary electrode for starting purposes.
  • an elongated positive column gas-filled electric discharge tube comprising an elongated envelope which may have a coating of fluorescent material on an inner surface thereof, encloses a pair of main electrodes disposed at opposite ends of the envelope.
  • An auxiliary electrode comprising a long thin electrically conducting strip extends along an inner wall of the envelope and is electrically connected to one of the main electrodes.
  • Conducting leads for providing exter nal circuit connections to the main electrodes and for connecting the auxiliary electrode to a main electrode are provided with an electrically insulating coating.
  • 1 designates an elongated positive column electric discharge tube connected through an inductor 2 to terminals 3 and 4 of a current supply.
  • the inner wall of the tube 1 is coated with a layer of fluorescent material 5.
  • Two main electrodes 10, disposed at opposite ends of the tube 1, are formed of a refractory wire coated with an electron-emissive active substance, for example, strontium and barium compounds.
  • Two long thin auxiliary electrodes 6 extending along and secured to inner facing surfaces of the tube 1 are connected, respectively, to one of the main electrodes 10.
  • the auxiliary electrodes 6 may be formed of any electrically conducting material, for example, graphite, enamel and a binder.
  • Each of the auxiliary electrodes 6 is connected to one of the main electrodes through a metal ribbon 7 and a short metal wire 8 which is connected to one of two current supply members 9 for the main electrode 10.
  • electrical connection between the main electrode 10 and the long thin auxiliary electrode 6 is provided by one of the current supply members 9 for the main electrode 10 which is connected to a metal wire 8 which, in turn, is connected to one end of a metal ribbon 7, the other end of which is connected to the auxiliary electrode 6.
  • the main electrode 10 is supported by;the current supply members 9 in a conventional vitreous bead.
  • auxiliary electrodes 6 have been shown as diametrically opposite to one another so that their relative spacing is equal to the internal diameter of the tube 1. However, it will be obvious that this spacing may be made considerably smaller.
  • potassium water glass a glazing, alundum, or
  • a glow discharge will occur between a main electrode 10, which serves as a cathode at that instant, and the unconnected end of the auxiliary electrode 6 to which it is not electrically connected.
  • This glow discharge will travel along the auxiliary electrode 6 to the other main electrode 10.
  • the main electrodes 10 are heated by the By coating all of the non activated parts of the tube 1, i. e., the parts of the tube which do not contribute to producing the arc discharge but which are, nevertheless, at the same potential as the main electrodes 10 with an insulating coating, they are made inaccessible to the glow discharge, which, consequently, concentrates on the activated part of the electrodes, i. e., the barium and strontium compounds. The result is that the transition of glow discharge to are discharge takes place at a lower voltage.
