Definitions

  • the present invention relates to a motor vehicle headlight according to the preamble of claim 1.
  • Such a motor vehicle headlight is from the FR 3 079 597 A1 already known.
  • a projection light module comprises a first projection light module which comprises a first semiconductor light source, a first projection lens and a first additional light source as well as a first light guide plate.
  • the first projection lens comprises a first optical axis and a first light entry surface that can be illuminated with the first additional light source through the first light guide plate.
  • the first additional light source is arranged on a narrow side of the first light guide plate such that light emanating from the first additional light source enters the first light guide plate transversely to the first optical axis.
  • the first light guide plate has a front emission side facing the first projection lens and a rear deflection side opposite the front emission side, as well as a first part closer to the first optical axis and a second part further away from the optical axis.
  • the first part and the second part are components of the first light guide plate.
  • a matrix function is understood here to mean that the high beam distribution has a plurality of matrix elements in the form of segments of the light distribution that can be individually darkened in order to avoid dazzling other road users and at the same time to achieve good illumination of the road with bright segments.
  • both projection lenses of the projection light modules appear luminous even when only the low beam is switched on in order to achieve a uniform appearance between the partial high beam and the low beam
  • an additional LED was previously installed on the LED board of the matrix high beam module and its light was directed to the lens entrance side via two metallized reflectors.
  • the arrangement of the reflectors was chosen so that the light path of the matrix function is not disturbed and the reflection surface of the second reflector is close to the image plane of the projection lens.
  • the matrix elements of the high beam distribution are generated via collecting lenses assigned to the respective LEDs, i.e. with a refractive attachment lens, and their imaging via the downstream common projection lens, the additional light used to brighten the projection lens runs via two metallized reflectors.
  • the optical system for lens illumination of the high beam module differs from that of the low beam module. This means that the light color of the additional light differs from that of the low beam.
  • the inevitable inclined arrangement of the second reflector of the known additional light means that it is not possible to get close enough to the image plane of the projection lens. This leads to an inhomogeneous appearance of the luminous lens.
  • a homogeneous luminance is generated at the height of the front optics of the matrix light module using a light guide plate.
  • the light guide is fed with additional light from one LED on the side of the matrix light LED board.
  • the light propagating within the light guide plate is directed towards the projection lens by prisms attached to the back of the plate. This results in homogeneous illumination of the light guide plate.
  • This and the position of the light guide in the image plane of the projection lens mean that the viewer already has a homogeneous appearance of the projection lens that corresponds to the shape of the projection lens, even if the projection lens is not completely illuminated for its actual purpose of generating a spotlight light distribution.
  • the tilted arrangement further improves the homogeneity of the illumination of the first projection lens with additional light.
  • the object of the invention is to achieve an even more uniform appearance between the partial high beam and the dipped beam.
  • a preferred embodiment is characterized in that the first projection light module is a high beam module.
  • the matrix high beam has the property that the appearance of the lens changes depending on the position of the light and dark matrix elements. Therefore, the invention, which ensures a more uniform appearance, has a particularly advantageous effect here.
  • the motor vehicle headlight comprises a second projection light module comprising a second semiconductor light source, a second projection lens and a second additional light source as well as a second Light guide plate
  • the second projection lens has a second optical axis and a second light entry surface which can be illuminated with the second additional light source through the second light guide plate
  • the second additional light source is arranged on a narrow side of the second light guide plate such that light emanating from the second additional light source enters the second light guide plate transversely to the second optical axis and the second light guide plate has a front emission side facing the second projection lens and a rear deflection side opposite the front emission side as well as a first part closer to the second optical axis and a second part further away from the second optical axis, and that the light guide plate is arranged in a tilted position in which the first part of the second light guide plate is further away from the second projection lens along the second optical axis than the second part of the second light guide plate.
  • the second projection light module has a mirror cover running from the back to the front in the motor vehicle headlight and that the light guide plate is arranged below the mirror cover.
  • This design creates a low beam module with improved illumination of the projection lens.
  • This design also surprisingly shows that the tilted arrangement further improves the homogeneity of the illumination of the second projection lens with additional light.
  • a further preferred embodiment is characterized in that the light color of the additional light source is unchangeable and differs from the light color of the high beam and/or the low beam.
  • This embodiment results in a fixed illumination of the remaining colorless light guide that is deliberately different in color from the light color of the high beam and/or the low beam and thus a correspondingly multi-colored illumination of the projection lens.
  • a further preferred embodiment is characterized in that the first light guide plate and/or the second light guide plate has at least one colored region.
  • the colored area is a light entry area of the otherwise colorless transparent light guide plate.
  • the colored region is a colored coated light entry region of the otherwise colorless light guide plate.
  • this attachment optic would be two-colored, as a so-called 2-component (2K) part.
  • 2K 2-component
  • the interface of the two components together with the entrance surface can be optimized with regard to a uniform colored illumination of the rest of the light guide (2.2).
  • Another variant instead of a two-color light guide plate consists in a coating of the entrance surface of the otherwise colorless light guide plate, the optical properties of which are designed in such a way that it is only transparent to light of a fixed color or wavelength and absorbs or reflects all light of other colors or wavelengths.
  • the light colour of the first and/or second additional light source is controllably variable and may differ from the light colour of the high beam and/or the low beam.
  • first and/or second additional light source has individually controllable, differently colored light-emitting diodes.
  • a temporally changing color of the lens illumination in particular a color that is deliberately different from the main light functions of the low beam and the high beam, cannot be realized with the above-mentioned state of the art.
  • This limitation of the possible appearances with which, for example, a colored welcome light can be created with the headlights is eliminated by this design.
  • a further preferred embodiment is characterized in that the individually controllable, differently colored light-emitting diodes comprise a red light-emitting light-emitting diode, a green light-emitting light-emitting diode and a blue light-emitting light-emitting diode.
  • An alternative to the use of the light guide plate according to the invention could be to use an attachment optic that is common to both functions, i.e., for the function of generating a light distribution and the function of uniform illumination of the projection lenses.
