Definitions

  • the invention relates to a high-performance mercury low-pressure amalgam lamp with an amalgam depot and a cladding tube surrounding the lamp, and to a manufacturing method for arranging the lamp in the cladding tube.
  • radiators as in DE 102 01 617 A1 and WO 96/31902 are disclosed, the radiator and the cladding tube in the discharge region and in particular in the field of amalgam deposits are separated by a radial air gap.
  • a heating element between radiator and cladding tube can be mounted so that it can also be used for cooling the amalgam deposit.
  • a thermally conductive layer is applied in the region of the amalgam deposit or the lamp is enclosed in the region of the amalgam deposit with a band.
  • An apparatus is an arrangement of a mercury low-pressure amalgam lamp with an amalgam and a surrounding this envelope tube, wherein the lamp has a mechanical contact with the cladding tube and according to the invention the lamp in the region of the amalgam of one of the Lamp adjacent band is annularly enclosed and the tape is the mechanical contact with the cladding tube. Tapes made of metal or plastic, in particular fluoropolymers, have proven useful.
  • a layer arranged in the region of the amalgam deposit between the radiator and the cladding tube is also suitable for heat transfer, in particular of metal or plastic.
  • a further device is an arrangement of a mercury low-pressure amalgam lamp with an amalgam depot and a surrounding this lamp cladding tube, wherein the lamp has a mechanical contact with the cladding tube and according to the invention the lamp in the field of amalgam deposits a layer for heat transfer in the field of amalgam from the radiator to the cladding tube, wherein the heat transfer coefficient of the layer corresponds at least to that of the cladding tube.
  • a procedural solution to the problem is a method for producing an assembly of high-performance mercury low-pressure amalgam lamps with an amalgam reservoir and a lamp surrounding the cladding tube, wherein a mechanical contact between the lamp and cladding tube in the region of the amalgam reservoir is prepared and used to cool the Amalgamdepots and according to the invention, in the region of the amalgam deposit, a band is applied annularly around the lamp.
  • the radiator with the band or the layer for heat transfer can rest loosely or firmly in the cladding tube.
  • attachment of the radiator in the cladding tube is advantageous to maintain contact.
  • FIG. 1 shows an emitter with strapped band in the region of the amalgam depot.
  • FIG. 2 shows a thermal bridge between the radiator and the cladding tube.
  • a radiator 1 is spanned in the region of the amalgam deposit 2 with a metal strip 3, wherein the metal strip 3 forms a mechanical contact with the cladding tube 4 after insertion into the cladding tube 4.
  • the metal strip 3 can be fastened in the form of a screw clamp around the lamp tube.
  • the tightening of a metal strip 3 has proven itself analogous to packaging technology.
  • the metal strip 3 is tightened with a tensioning device, superposed and fastened the superimposed sections together. It has proven useful to attach the superimposed ends with a cuff.
  • radiators 1 with a power of 500 watts and 800 watts, or a power density of 3 W / cm and 5 W / cm are operated in an externally water-cooled cladding tube 4. For this purpose, the radiator 1 are pushed into the cladding tube 4, on which they ultimately rest with the metal strip 3.
  • the lamp corresponds to any mercury low-pressure amalgam lamp with an amalgam depot 2, as can be seen, for example, the cited prior art.
  • the band is formed as a clamp which clamps the radiator.
  • a 1.5 mm wide band of polytetrafluoroethylene (PTFE) is applied.
  • the thickness of the PTFE tape is 0.7 mm and for the radiator with a power density of 5 W / cm, the thickness of the PTFE tape is 1 mm.
  • a fluoroelastomer is formed as a clamp which clamps the radiator.
  • the layer 3 can be applied with a paste according to the thick-film technique.
  • a layer 3 is arranged between the radiator and the cladding tube.
  • the layer 3 is applied according to the paste technique and then sintered.
  • thermoplastic layer of fluoropolymer in particular PFA or FEP, is applied as a melt on the radiator or in the cladding tube or between the radiator and the cladding tube.
