Definitions

  • the invention relates to an optical coupling body for coupling an optoelectronic device to a vehicle window, with a transparent coupling medium of a silicone material, which is surrounded by a peripheral edge.
  • the invention further relates to a method for producing such a coupling body.
  • Optoelectronic devices such as rain or light sensors or camera arrangements are usually coupled by means of coupling body to vehicle windows.
  • the coupling body has a coupling medium, which usually consists of a highly transparent silicone material and is used for optical coupling of an optically active component of the optoelectronic device, such as a glass prism, a light guide or a camera, hereinafter generically referred to as optics body, to a disc of a motor vehicle ,
  • the coupling medium has in addition to the photoconductive function, the task to completely fill gaps between the optical body and the vehicle window to avoid sudden changes in the refractive index.
  • the coupling medium usually consists of a low-viscosity gel-like material whose shape can be well adapted to the surfaces of the components to be coupled to each other.
  • Such materials may be designed to cure after application or self-curing after some time. At least during application, however, these materials are not dimensionally stable. Therefore, such a coupling medium is encompassed by a peripheral edge, which prevents a flow during the Ausbringphase.
  • the German patent application DE 101 19 219 A1 shows an optoelectronic device for a motor vehicle, with a transparent coupling medium of a silicone material, which is surrounded by a peripheral edge, which is integrally formed on a surface of a housing.
  • the edge of the coupling medium is formed here by a housing part, there is the problem that the edge laterally limits the beam path. This limitation of the beam path is disadvantageous, as this obliquely incident or falling light is absorbed and thus not usable for the optoelectronic device. To compensate for the coupling medium must be correspondingly large area, which results in a total of a relatively large-scale optoelectronic device.
  • the optoelectronic device could often be made considerably smaller. In principle, this could be carried out transparent to the edge formed by the housing part. However, this would result in the problem that the housing material generally has completely different optical properties than the coupling medium and thus can not be used visually equivalent effect. Also, a rigid housing edge does not mate well with a vehicle window.
  • the first part of the object is achieved in that the peripheral edge consists of a silicone material which has a higher viscosity than the silicone material of the coupling medium.
  • the second part of the object is achieved in that in a first method step, the peripheral edge is applied to the vehicle window or to the optical body of the optoelectronic device, and that in a second process step, the peripheral edge is filled with the silicone material forming the coupling medium.
  • the optical body is in this case that optical component which is optically coupled to the vehicle window by the coupling medium or the coupling body.
  • the optical body can be embodied, for example, as a prism, a lens, or a light-conducting body.

  • the application of the silicone material can also be effected by nozzles which can be positioned in three dimensions, comparable to the print head of an inkjet printer.
