Definitions

  • the invention relates to a gas discharge lamp which contains two electrodes in a gas-filled, translucent housing, the outer electrode connections of which are provided with cooling fins.
  • Gas discharge lamps of this type are manufactured for different outputs.
  • a high performance is e.g. required if the gas discharge lamp is used as a laser pump tube.
  • the invention is based on the object of designing a gas discharge lamp of the type mentioned at the outset in such a way that it is particularly suitable for high outputs, with optimum heat dissipation being ensured.
  • a cooling liquid flows directly around the outer electrode connections, including the cooling fins.
  • the heat generated by the gas discharges is optimally dissipated via the cooling fins.
  • the cooling fins can lie with the housing in a translucent tube through which a cooling liquid flows. This ensures a particularly intensive heat transfer between the cooling fins and the coolant.
  • the electrode connections are expediently made of a good heat-conducting material, e.g. made of copper.
  • the electrode 1 shows a laser pump tube with a glass tube 1, in which two electrodes 2, 3 are melted.
  • the electrode connections 4, 5 consist of copper, in which the heat-resistant electrodes 2, 3 are inserted. They have cooling fins 6, 7.
  • the electrode connections 4, 5 are inserted together with the glass tube 1 and the electrodes 2, 3 in a translucent tube 8 and are sealed at the ends by means of seals 9, 10.
  • the tube 8 is with connection piece 11, 12 for the supply and discharge of a cooling liquid, for. B. provide water.
  • the electrode connections 4, 5 are made of a highly thermally conductive material that quickly dissipates the heat from the interior of the glass tube 1.
  • FIG. 2 shows that connection bodies 13 can be placed on the electrode connections 4, 5, which enclose the electrode connections 4, 5 and are inserted with the help of seals in a further pipe 8a relative to the pipe 8. This results in a particularly intensive washing of the electrode connections 4, 5 with the cooling liquid.
