Definitions

  • the invention relates to a high-pressure discharge lamp according to the preamble of claim 1.
  • Such lamps are in particular high-pressure discharge lamps for general lighting or for photo-optical purposes.
  • the object of the present invention is to provide a high-pressure discharge lamp according to the preamble of claim 1, which is compact and yet has sufficient Platzertik.
  • the invention relates to space-protected lamps with only one outer bulb and an additional plastic sheath in the low-wattage bath Anlagen Weg.Hierbei plastic sheathing serves as a Platzerschutz for possible lamp destruction by negative influences.
  • the plastic must be suitable for high temperatures and photometrically suitable.
  • space-protected lamps are still provided with a second outer bulb.
  • a thin tube made of high temperature resistant plastic is pulled over the lamp and shrunk by thermal treatment on the bulb of the lamp.
  • the ratio of the wall thickness of the shrink tubing to the diameter of the shrink tubing must be between 1:45 and 1: 300.
  • a glass tube section can be positioned in the burner level before joining the tube, which cools the plastic tube in this area.
  • the height of the section is one to four times the burner body diameter.
  • the inside diameter of the glass section should be between 1.01-1.05 times the outside diameter of the lamp.
  • the wall thickness of the glass tube section is preferably between 0.5 and 1.2 mm.
  • a suitable plastic in the form of a tube is in particular, at least proportionally, polycarbonate, polyester, poly-methyl methacrylate or polyolefin.
  • the plastic is transparent, UV-stable and high-temperature stable and preferably consists of Teflon or PTFE.
  • the tube is preferably not simply applied to the outer bulb, but it is introduced in the area where the highest temperature occurs, a pad between the tube and outer bulb.
  • FIG. 1 shows the structure of a high pressure discharge lamp 1 highly schematic. It has a discharge vessel 2 which is accommodated in an outer bulb 3.
  • the outer leads 4 of the discharge vessel, which contact electrodes inside, are connected to two frame wires 5 and 6.
  • a short frame wire 5 leads to a first foil 7 in a pinch 8 of the outer bulb.
  • a long frame wire 6, often called stirrup wire, leads to a second film 7 in the pinch 8.
  • the discharge vessel 2 has at its ends in each case a capillary 10, as known per se, and a filling of an ionizable gas, usually argon or Xenon, mercury and metal halides, also known per se.
  • Two electrodes are located inside the discharge vessel opposite, as also known and not shown here.
  • the outer bulb 3 is surrounded by a tube 15 made of Teflon, which bears tightly against the essential surfaces of the outer bulb, at least over an axial length, which surrounds the discharge vessel.
  • FIG. 2 shows an embodiment that takes into account the high temperature load in an improved manner.
  • a special holder 20 made of metal is mounted on the outer bulb. He is shaped so that it surrounds the pump nozzle 21 of the outer bulb with a ring member 32.
  • a bent part 22 is pulled down to the height of the discharge vessel. This part has a bead 23 as a spacer approximately at the level of the discharge distant capillary 24 of the discharge vessel and a U-shaped holder 25 approximately at the level of the discharge near capillary 26.
  • a tube 27 is at the level of the discharge vessel 2, preferably made of highly heat-resistant glass, as a temperature protection placed outside on the outer bulb 3 and there by means of the holder 25 and the bead 23 oriented and fixed. Externally on the tube 27, a plastic jacket 28 is attached, preferably a shrink tube, which adapts to the different geometry of the outer bulb, including the holder 20 and the tube 27.
  • the discharge vessel does not have to be made of ceramic, it can also be made of quartz glass or similar. be made.
  • a pump neck is not absolutely necessary, but it facilitates the attachment of the retaining ring here.
  • the retaining ring can also be designed differently, in principle, exterior warts applied to the outer bulb are sufficient Glass or similar, which convey the basic task of a spacer.
  • FIG. 3 shows such an embodiment in which warts 30 made of glass over the circumference of the outer bulb 3 in two lines are applied approximately at the level of the two capillaries 24, 26.
  • the tube 27 is positioned on this.
  • the length of the shrink tube should be at least 70% of the axial length of the cylindrical outer bulb.
  • a big advantage of the shrink tubing is that it can also be used for bulbous outer bulbs, see FIG. 4 , There, the outer bulb 3 shows a central bulge 37, over which the shrink tube 15 extends.
  • a high-pressure discharge lamp has a ceramic discharge vessel which is accommodated in an outer bulb, wherein the outer bulb is also surrounded by a splinter protection, which bears tightly against the outer bulb.
  • the outer bulb is socketed on one side and the discharge vessel is equipped with two ends.
  • the splinter protection is a heat shrink tube.
