Definitions

  • the invention also relates to a motor vehicle headlight with at least one such device.
  • Such signal light or lighting devices are used for various purposes in motor vehicles or in motor vehicle headlights.
  • Signal lighting devices are used, for example, as side marker lights, which are provided as independent structural units or can be integrated into a motor vehicle headlight.
  • the size and the design are usually specified by the motor vehicle manufacturers, with design requirements specifying, for example, a relatively large luminous surface for the signal lighting device with a small installation space at the same time.
  • Such design drafts e.g. of signal light functions/signal lighting devices, often contain flat elements such as discs or thick-wall optics, which are to be illuminated from behind with corresponding optical elements, in particular with one (or more) light guide bodies with the most uniform possible luminance.
  • the light-conducting body (or several light-conducting bodies) of the signal lighting device illuminate a diffuser or other optics, such as thick-wall optics, of the signal lighting device or the motor vehicle headlight evenly or homogeneously.
  • the deflection device comprises at least one decoupling surface, which decoupling surface is set up to break that part of the light beams which are incident essentially in the first light guide main propagation direction on the at least one decoupling surface in such a way that they emerge from the light guide body in the exit direction.
  • the light guide body typically has one or two, sometimes more light guide fingers, which run transversely to the first light guide main propagation direction, in which light from the light source is coupled into the light guide body (the/the light guide fingers run in or in the second light guide main propagation direction(s)).
  • light from the light source is distributed in this direction(s) which is transverse to the main direction of light propagation, which when the device is installed in a motor vehicle corresponds, for example, to the longitudinal axis of the vehicle, and then in the light guide finger(s) again in the first main propagation direction to be deflected.
  • part of the light moving in the first main propagation direction of the light guide can emerge from the light guide so that an optic (diffuser, thick-wall optics, ...) arranged in front of the light guide, for example, can ) can also be illuminated in this area, i.e. "in front of" the light source.
  • the other part of the coupled-in light is totally reflected and enters the fiber optic finger or fingers and, as described above, exits from it/them again in the first direction of light propagation.
  • central areas in front of the light source and the coupling area can be illuminated, but on the other hand, areas further away from the light source (in front of the fiber optic finger(s)) can also be illuminated by the total reflections.
  • the homogeneity can thus be significantly improved, and the light from the light source can also be used more efficiently, and if the light source includes LEDs, LEDs can be saved, for example, or weaker LEDs can be used.
  • the light-guiding body consists, for example, of a transparent, light-guiding material, for example a transparent polycarbonate such as Tarflon.
  • the deflection device to have a plurality of reflection surfaces which deflect light beams into the second main propagation direction of the light guide.

  • the deflection device can comprise a plurality of decoupling surfaces which essentially break up light beams incident on them in the first light guide main propagation direction in such a way that these emerge from the light guide body in the exit direction.
  • Reflection surfaces and decoupling surfaces are preferably arranged adjacent to one another, in particular adjoining one another, with two adjacent reflection surfaces/decoupling surfaces preferably being separated by one decoupling surface/reflection surface each. For example, this can be advantageous for exiting the light as homogeneously as possible in the central area, opposite the light source.
