Definitions

  • the invention relates to a lighting device for a vehicle according to the generic features of claim 1.
  • a lighting device is known for example from DE 36 35 471 AI.
  • a lamp is disclosed which is arranged on a vehicle exterior mirror and which is fixed immovably in a wing mirror holder on a front side vehicle door at the rear and down.
  • the light can be switched on at a distance from the vehicle by the portable transmitter of an infrared remote control, which then illuminates the entry area on a vehicle side.
  • the light coming from the lamp is directed downwards so that other road users are not dazzled.
  • the lamp of the lamp in the wing mirror holder for drivers of vehicles is arranged hidden.
  • the lamp usually creates an elliptical illumination field and an uncontrolled decrease in brightness from the center to the edge.
  • DE 198 05 771 AI discloses a lighting device for motor vehicles, which is equipped for fastening to a motor vehicle with a housing in which an electric light source is arranged.
  • One or more light-emitting diodes are used as illuminants, which essentially emit white light.
  • the lighting device can be heat of the light-emitting diodes can be integrated particularly easily into existing components of the motor vehicle, in particular into the exterior mirrors, interior mirrors, moldings and door handles, and serve to illuminate the area around the vehicle or the vehicle interior.
  • the lighting device has at least one light-emitting diode, a lens system, in particular for beam expansion, being provided in the beam path of the light illuminated by the light-emitting diode.
  • the disadvantage here is that complex projection optics are required to project a predetermined brightness distribution, such as a logo. Only uniform illumination fields or illumination fields with an uncontrolled decrease in brightness from the center to the edge are usually produced by the entry lights. A given distribution of lights such as the insertion of a logo in the illumination field would, however, require expensive projection optics.
  • the object of the invention is to provide a lighting device for a vehicle with a predetermined illumination field with a simple and inexpensive lamp.
  • a predetermined illumination field can be implemented simply and cheaply by means of a light-emitting diode, the light of this light-emitting diode being projected into the predetermined illumination field by means of a single free-form surface.
  • the free-form surface was previously calculated according to the projection specifications for the illumination field.
  • FIG. 1 shows a vehicle with an illumination device with a schematically illustrated illumination field
  • Fig. 3 is a schematic representation of a possible lighting field.
  • the vehicle 1 shows a vehicle 1 with an illumination device with a schematically illustrated illumination field 2.
  • the vehicle has an illumination device arranged on its outside mirror 3, which serves as an entry light.
  • the vehicle has arranged a projection unit 4 on its outside mirror 3, so that when the lighting device is activated, an illumination field 2 is created in a wide area next to the side door.
  • the illumination field 2 is, for example, a uniformly illuminated rectangular illumination field.
  • the evenly illuminated illumination field can include a brightly highlighted logo or a darkly reset logo.
  • the illumination field 2 can have any geometrical shape, such as circular, oval, rectangular, square and others.
  • the complete information for the illumination field 2 is in the free-form surface 6. This free-form surface 6 was previously calculated with the desired specifications.
  • FIG. 2 shows a schematic illustration of a lighting device 4 as it is arranged as an entry lamp in the outside mirror 3 of a vehicle 1.
  • the lighting device 4 has a projection element 6 and a light-emitting diode 5, the light of which is expanded by the projection element 6 with the free-form surface for illuminating the illumination field 2.
  • This free-form surface 6 contains, via its reflection properties, information about the shape and logo of the illumination field 2 in FIG. 3.
  • the imaging lens 6 is preferably made of PMMA with an outer cylinder of 40 mm.
  • a light-emitting diode 5 is arranged, the emitted light of which is imaged by the imaging lens 6 in such a way that an illumination field 2 with a brightly illuminated illumination field 2 and a brightly emphasized logo 7 is produced, as shown in FIG. 3.
  • the projection element 4 is a free-form surface.
  • the geometry of the surface of the free-form surface 6 is adapted by means of corresponding calculations so that the free-form surface 6 depicts a highlighted or shaded logo 7 in the illumination field 2.
  • a logo 7 other characters are also possible, which are emphasized in the otherwise not necessarily uniform illumination field 2 or are darkly reset.
  • FIG. 3 shows a schematic illustration of a possible illumination field 2.
  • the illumination field 2 is shown two-dimensionally in the x and y directions, corresponding to the road surface next to the driver's door.
  • the entire lighting field is on a black background. This background symbolizes the road surface next to the driver's door.
  • a brighter highlighted logo 7 is shown on the uniformly illuminated illumination field 2.
  • the information for this entire illumination field 2 with the Logo 7, which is highlighted more brightly, is completely in the configuration of the free-form surface 6, as shown in FIG. 2.
  • the free-form surface 6 is arranged in the beam path of the light-emitting diode and widens the light beam in such a way that the illumination field 2 is created.
