Definitions

  • the present invention relates to a radiation arrangement, in particular an infrared radiator, with at least one radiation source running in the direction of the longitudinal axis of a cladding tube, which is closed at both ends, with a metallic, electrical connection part at each end of the cladding tube and with at least one of the changes in length of the radiation source receiving, springy intermediate part within the cladding tube, on the one hand with an electrical connector and on the other hand firmly connected to the radiation source is.
  • the infrared radiation source shown in this document has a cladding tube made of a material transparent to infrared radiation, which has an electrical Contains ladder made of carbon fibers with an electric power supply are connected.
  • the cladding tube is sealed at its ends and can either be evacuated be or be filled with a gas such as argon. This will be Radiation sources with a fast response created at temperatures above 1.200 ° C are operable.
  • DE-A1 44 19 285 describes a radiation arrangement, in particular an infrared radiator, with at least one areal trained radiation source.
  • the radiation source is a carbon ribbon that is in several, related sections is arranged, wherein the sections are held at their ends in conditions, of which at least the first and the last are formed as contact; This makes this radiation arrangement also resistant to temperature changes over a longer period of time and has a low Sluggishness.
  • the present invention the object, a radiation arrangement of the type mentioned in such a way, that they in particular with small Leuchtrohr- or Hüllrohr bemessern, for example with inner diameters in the range below 12 mm, can be constructed, wherein At the same time it is ensured that length changes in the radiation source are compensated can be.
  • a Measure taken which provides as a compensation element for the change in length, a molybdenum sheet use, which has at least one folding section, the sufficient is to compensate for the occurring length changes. It has been shown that with a so-folded molybdenum-sheet radiator, especially carbon radiator, with very small Luminous or cladding tube diameter can be produced because with the molybdenum sheet the high current loads, despite the small, available inner cross section of the Strahlers, can be included as the molybdenum sheet under the exploitation of the full inner diameter of the cladding tube can be dimensioned.
  • the molybdenum sheet should have a thickness in the range of 0.07 to 0.1 mm, with a preferred width of the molybdenum sheet in the range of 0.5 to 0.7 mm per 1A current load.
  • the ratio of width to height of the folded molybdenum sheet in Range from 1: 0.5 to 1: 1, preferably from about 1: 0.75.
  • the radiation arrangement is particularly suitable for inner diameter of the cladding tube, which are less than 12 mm.
  • the folding section with multiple kinks be provided, which, seen in the axial direction of the cladding tube, zig-zag or harmonica-like arranged one behind the other.
  • the length of the radiation source is one in the range of 400 to 1000 mm, the number of folds or kinks preferably at at least 10. If length of the radiation source in the range of> 1000 mm is required should the number of folds or kinks be at least 12.
  • a folding section can also be in the area of both terminal ends the source of radiation, with the respective, by the pinch at the end of the Cladding tube outwardly guided pins are connected, be arranged.
  • Such a folding section with at least two Kinks transverse to the longitudinal axis of the cladding tube in conjunction with a carbon ribbon as Radiation source.
  • the radiation arrangement as shown in Figure 1 in a perspective view, comprises a cladding tube 1, along the axis of a band-shaped radiation source 2 is guided, which is in this example is a carbon ribbon.
  • the inner diameter of this cladding tube 1 is about 10 to 12 mm.
  • a contact plate 5 is fixed.
  • the one contact plate 5 at the one end 3 of the radiation source 2, in Figure 1, the right-hand end, is connected to a contact pin 6, which leads into the pinch 4, in the area of the Contact pin 6 merges into a molybdenum foil 7, which in turn at its other end with a pin-shaped, electrical connection part 8 is connected, through the pinch 4 out leads to the outside to contact the spotlight can.
  • the band-shaped Radiation source 2 in turn via a contact plate 5, connected to an intermediate part 9.
  • This intermediate part 9, which consists of several folding sections 15, is also in one enlarged view in Figure 2 shown.
  • Each folding section 15 has several Kinks 10; at the free ends in each case a connecting lug 11 is present.
  • the right end of the intermediate part 9 on its tab 11 with the band-shaped radiation source 2 is fixed in the region of the contact pad 5, the other end, i.e., the other one Connecting lug 11, in turn connected to a contact pin 6, in the pinch 4 leads in there and which is connected there with a molybdenum foil 7, which in turn is the radiation source 2 connects via a pin 8 with the outside.
  • the band-shaped Radiation source 2 changed in length, while in this case each maintains its voltage.
  • This intermediate part 9 is suitable to withstand the high current loads, as the the intermediate part 9 and the folding sections 15 forming molybdenum ribbon under utilization of the entire cross section of the interior of the cladding tube 1 with respect to the bandwidth 13th and the height 16 of the individual folding sections 15 can be dimensioned.
  • the intermediate part 9, as shown in Figure 2 , and is used in the radiation arrangement of Figure 1, has a total of nine kinks 10, wherein the kink 10 is not counted in the region of the terminal lugs 11 here.
  • Such a dimensioned intermediate part 9 is particularly suitable for radiators having lengths in the range of 1000 to 1500 mm.
  • the width 13 of the molybdenum sheet 12, from which the intermediate part 9 is formed, is designed so that it corresponds approximately to half the inner diameter of the cladding tube 1, wherein as a dimensioning rule, the width of the molybdenum sheet 12 with 0.5 - 0.7 mm / 1A current load should be designed.
  • the ratio of width 13 to height 16 (see Figure 2) of the folded molybdenum ribbon 12 is in the range of 1: 0.5 to 1: 1, with about 1: 0.75 being preferred.
