Definitions

  • the present invention relates to a method for producing a lighting device for a motor vehicle according to the preamble of claim 1 and to a lighting device produced by this method.
  • the illumination devices described therein comprises a light source, for example, designed as a light emitting diode (LED) or diode laser and an optical fiber connected to the light source and a light guiding fiber surrounding the transparent tube.
  • the optical fiber is provided with scattering structures, so that during operation of the illumination device, portions of the light propagating through the optical fiber emerge laterally from the optical fiber and the tube. This results in sections a decorative light line.
  • the tube and the optical fiber are fastened to a holder with clips. In this case, the tube and the optical fiber are selectively overlapped so that the light effect of a linear light source is disruptively interrupted at these joints.
  • the tube surrounding the optical fiber is inserted into grooves of a transparent, plate-shaped holder and adhesively bonded therein.
  • the emerging from the optical fiber in the transverse direction of light is coupled to a large extent in the plate-shaped holder so that it lights up.
  • the light effect of a linear light source is adversely affected by the luminous support.
  • An adhesive bond requires very accurate positioning and metering of the adhesive to avoid messy splices. Furthermore, in typical adhesive bonds with sufficient strength, a fixation of the bond to the adhesive curing is required.
  • the problem underlying the present invention is the disclosure of a method of the type mentioned, with which effectively a mounting of the tube with the optical fiber can be achieved at the Flalterung, without affecting the light effect generated by the optical fiber. Furthermore, a lighting device of the type mentioned is to be created, in which the Lichtleit fiber forms a possible uninterrupted light line in the operation of the lighting device.
  • the adhesive is cured by irradiation with UV light, so that the tube is connected to the Flalterung by the bonding process.
  • UV-curing adhesives achieve sufficient strength within a few seconds and are comparatively easy to meter. Compared with other joining methods, a very defined joint is produced.
  • the tube of pressing means is pressed against the area of the holder provided with the adhesive. Due to the very fast-curing plastic, the pressing means must be pressed only for a short period of time to the tube. It can be provided that the irradiation of the adhesive with UV light takes place in the transverse direction of the optical fiber through the optical fiber and / or through the tube and / or by the pressing means. In this way, a bonding takes place exclusively at the back of the tube, so that the adhesive bond does not affect the light effect generated by the optical fiber.
  • the tube is glued to the holder and / or another suitable holder at a plurality of locations spaced over its longitudinal direction. It can thereby be achieved that a comparatively long uninterrupted light line is generated.
  • the tube is bent prior to the bonding process in order to take the form provided for the lighting device.
  • the tube is bent during the bonding process to take the intended form for the lighting device, wherein in particular the tube is heated before and / or during the bonding process.
  • the lighting device is produced by a method according to the invention.
  • the illumination device may comprise a light source, an optical fiber connected to the light source and a transparent tube surrounding the optical fiber, wherein the optical fiber is provided with scattering structures, such that during operation of the illumination device portions of the light propagating through the optical fiber laterally emerge from the optical fiber and the tube.
  • the tube is attached at least in sections only on one side to at least one holder, so that there is at least partially not interrupted luminous line by the lateral light exit from the optical fiber and the tube during operation of theansvor- direction.
  • the light effect produced by the optical fiber is not influenced by the only one-sided support.
  • the inner diameter of the tube is at least 1.5 mm larger than the outer diameter of the optical fiber and / or that the outer diameter of the tube is at most 4.0 mm. Due to the comparatively large inner diameter of the tube, the optical fiber can move relative to the tube during bending. Due to the maximum 4.0 mm outer diameter, a filigree lighting effect can be guaranteed.
  • Fig. 1 is a schematic sectional view of a detail of an inventive
  • a lighting device comprises a non-illustrated light source, which may be formed, for example, as a light emitting diode (LED) or Dio laser.
  • the lighting device further comprises an optical fiber 1, in which the light of the light source can be coupled.
  • the light-conducting fiber 1 may be provided, for example, in its core with scattering structures, so that during operation of the lighting device, portions of the optical fiber 1 propagating through the light can emerge laterally from the optical fiber 1.
  • the lighting device further comprises a tube 2, in which the Lichtleitfa ser 1 is arranged.
  • the tube 2 can be a transparent plastic tube.
  • the inner diameter of the tube 2 at least 1, 5 mm larger than the outer diameter of the optical fiber Be 1.
  • the outer diameter of the tube 2 may be 4.0 mm or smaller than 4.0 mm, for example.
  • the lighting device further comprises a holder 3, which may be, for example, a part of a non-illustrated housing of the lighting device.
  • This holder 3 has a contour 4, which is partially hollow cylindrical and corresponds to the outer contour of the tube 2.
  • the tube 2 is attached to a plurality of spaced apart over the longitudinal direction of the tube 2 points on the contour 4 of the holder 3 or other comparable contours 4 of a holder 3 by a UV-curable adhesive 5.
  • pressing means 6 are provided, which also have a partially hollow cylindrical contour 7, which corresponds to the outer contour of the tube 2.
  • the pressing means 6 and the contour 7 are transparent in the illustrated embodiment, in particular transparent to UV light.
  • the contour 7 of the pressing means and the contour 4 of the holder 3 thereby position the tube 2 by its shape adapted to the outer diameter of the tube 2.
  • the adhesive 5 is applied with UV light 8.
  • the UV light 8 can be, for example, a UV laser beam.
  • the UV light 8 is supplied to the adhesive 5 through the pressing means 6 and through the tube 2 and optionally also through the optical fiber 1.
  • the pressing means 6 are removed. If the tube 2 is to have a single or multiple curved shape together with the optical fiber 1 in the illumination device, the tube 2 can be correspondingly bent before the adhesive process. Alternatively, a corresponding shaping can also take place during the joining process by bonding to the adhesive points spaced apart in the longitudinal direction of the tube 2. For this purpose, the tube 2 is heated and deformed before and / or during the bonding.
