Definitions

  • a high-pressure discharge lamp which has a structure in accordance with the characterizing features of claim 1. Further advantageous features of the lamp can be found in the subclaims.
  • the interior of the piston necks is hollow and, because the bases attached to the ends of the necks have a corresponding opening, air can flow through them. This enables additional heat dissipation from the bulb neck during lamp operation. This heat dissipation can be further reinforced by a rod made of heat-dissipating material, which protrudes in isolation into the hollow cylindrical opening of the piston neck.
  • the structure of the lamp necks allows operating currents of up to 130 A without damaging the melts and thus reducing the average lamp life. With these high currents and power consumption of up to 24,000 W, high-pressure discharge lamps can be built that emit luminous fluxes of over 2 million lm with a metal halide fill.
  • the invention also relates to a method for producing a high-pressure discharge lamp, as claimed in the claims.
  • the construction of the inner tube from two tubes offers the advantage that when the sealing films are subsequently melted, a visual check of the melting quality is made possible.
  • the films are only melted well if the quartz glass of the two inner tubes has softened to such an extent that the outer contours of the tubes are no longer visible.
  • the lamp bulb 1 made of quartz glass consists of a largely cylindrical, rotationally symmetrical discharge space 2, on the two ends of which lie in the axis, a cylindrical bulb neck 3, 4 is melted.
  • the two pin electrodes 5, 6 made of tungsten protrude into the discharge space 2, the shaft ends of which are inserted into a central hole in a circular cylindrical disk 7, 8 made of molybdenum and soldered firmly with platinum solder.
  • the disc 8 made of molybdenum with the tungsten electrode 6 attached to it and the four welded molybdenum sealing foils, of which only two 14, 16 are visible, is placed on the inner tube consisting of the two tubes 20, 21 pushed into one another.
  • the sealing foils 14, 16 run parallel to the axis of the piston neck between the outer tube 19 and the outer tube 20 of the inner tube.
  • a hollow cylindrical tube piece 24 made of quartz glass is placed over the shaft of the pin electrode 6 and, after melting, provides a seal between the discharge space 2 and the molybdenum disk 8.
