Definitions

  • the invention relates to a lighting, which is arranged in the interior of a motor vehicle, with a lighting means and a transparent cover.
  • Illuminations are known from the prior art, for example DE 101 51 599 A1, DE 102 59 236 and DE 102 31 324.
  • Such lights have two separate light sources, such.
  • Each of these light sources can be switched on or off via electrical switches.
  • these lights are relatively expensive to manufacture and maintain.
  • the object is achieved with a lighting, which is arranged in the interior of a motor vehicle, with a lighting means and a transparent cover, wherein the cover has at least two different optical functional areas.
  • the illumination according to the invention has the advantage that only one illuminant is required for a plurality of illumination functions.
  • the illumination according to the invention can be used as a reading light and as interior lighting.
  • the lighting according to the invention is simple and inexpensive to produce.
  • the light beams of the light source can be optionally assigned to one or more optical functional areas.
  • the lighting comprises a lighting means, which can be any light source known to a person skilled in the art, for example a light bulb, an LED, an OLED 1, an optical waveguide or the like.
  • the color of the light is selectable and may be different for the different optical functional areas.
  • a reflector can be arranged be to at least partially focus the light emitted by the light source in a main radiation direction.
  • the light source can be operated with different light intensities and switched on and off.
  • the luminous intensity may be different for the individual optical functional areas.
  • This light source is preferably covered by a cover which is transparent to the radiated light, at least in its main emission direction.
  • the main direction of emission is the direction in which the light should emit light. In the present invention, this is the vehicle interior.
  • the cover is a glass or more preferably a plastic component.
  • This cover has two different optical functional areas according to the invention. These optical functional areas differ in the angle of the radiation of the light and / or in the bundling and scattering of the radiation.
  • a comparatively concentrated reading light can be generated with the one functional area, with the other functional area, for example, a comparatively diffused room light for illuminating, for example, the interior of the motor vehicle.
  • the different functionalities in the sense are also two reading lights, which are aligned in different directions.
  • a functional area can also be a simple pane that is simply irradiated.
  • the functional area can also be a diffuser for the light.
  • the different optical function are achieved by a design of the surface and / or the cross section of the respective area.
  • the area can be designed as a converging lens, which bundles the emitted light into a reading light and / or steers in the direction of the driver or the passenger of the motor vehicle.
  • the surface of the area can also be designed, for example roughened and / or structured, so that the light emitted by the illuminant is scattered.
