Definitions

  • the invention relates to a motor vehicle light module comprising at least one microprojector, and at least one at least partially translucent projection wall element, the at least one microprojector being set up to produce a light distribution, the light distribution onto the at least one at least partially translucent projection wall element in the form of a predeterminable light pattern is projectable.
  • the invention relates to a motor vehicle headlight or a motor vehicle with at least one such motor vehicle light module.
  • motor vehicle light modules of the type mentioned above are known in the prior art. Such motor vehicle light modules are often used in (visual) communication systems or as design light, for example in order to project corresponding signs onto the road surface in the immediate vicinity of a motor vehicle in which they are installed.
  • the object of the present invention is to provide a motor vehicle light module with which luminous motor vehicle branding is possible and which can be used as a communication element (with the analog environment).
  • the object is achieved in that the predeterminable light pattern is visible in a switched-on state of the motor vehicle light module on a side of the projection wall element facing away from the microprojector and contains optically represented information.
  • the information can be represented in the form of a sign, a logo, a lettering or the like.
  • the at least one projection wall element can thus at least partially scatter and at least partially absorb the light forming the light distribution, as a result of which the predeterminable light pattern — seen from the motor vehicle light module — becomes visible to the outside.
  • the motor vehicle light module according to the invention makes it possible, for example, to significantly enhance luminous design branding, since a luminous lettering, for example, is clearly more visible at night.
  • the motor vehicle light modules according to the invention can also be used for communication elements (with the analog world) in the field of autonomous driving.
  • the microprojector has at least one light source that is set up to generate light and a projection device, wherein the projection device is arranged downstream of the at least one light source in the direction of radiation and is set up to shape the light distribution and onto the at least one at least partially transparent projection wall -Project element.
  • the projection device has at least one projection lens and at least one diaphragm, the at least one diaphragm being arranged in a focal plane of the at least one projection lens and having diaphragm edges, which diaphragm edges have a shape corresponding to the predefinable light pattern.
  • the diaphragm is preferably arranged in a plane transverse to the optical axis of the microprojector (see figures). In this case, the aperture can lie entirely in the focal plane instead of just cutting it.
  • the diaphragm edges form at least one symbol which is information to be displayed, which symbol preferably lies completely in the focal plane.
  • the projection device has a plurality of projection lenses arranged in an array - projection lens array - and a plurality of diaphragms - arranged in an array - an aperture array, with each projection lens being assigned one, preferably exactly one, aperture , the diaphragm edges of different diaphragms being of the same or different design.
  • each projection lens being assigned one, preferably exactly one, aperture , the diaphragm edges of different diaphragms being of the same or different design.
  • both the projection lens array and the aperture array are in one piece.
  • the projection lens array can be an optical body made of a material such as plastic.
  • the optic body can also be a composite of a glass plate and a silicone lens array adhering to the glass plate.
  • the projection lens and / or the aperture array preferably extend in a plane transverse to the optical axis.
  • the at least one projection lens has a lens diameter between 1 and 5 mm, preferably 2 mm, preferably at least partially made of glass or silicone, and / or the projection wall element of the at least one projection lens by approximately 1 cm is about 10 cm apart.
  • the light intensity on the projection wall element is sufficient to make the light pattern visible.
  • the light pattern at a distance of 10-25m from a white wall can hardly be measured, so no problems with the approval (maximum scattered light values) are to be expected. No powerful light sources are required either. If, as stated below, low-power LED light sources are used, they do not need a heat sink, which is provided for cooling these LED light sources.
  • the at least one light source is a semiconductor-based light source, for example an LED light source.
  • a semiconductor-based light source for example an LED light source.
  • these can emit light of different colors. This can arouse the attention of passers-by or other road users much more effectively.
  • the microprojector additionally comprises a collimator arranged between the at least one light source and the projection device. This can ensure, for example, more uniform illumination of the diaphragm (s).
  • the at least one projection wall element is a transparent layer with a grained surface or a milky plastic or glass pane or a clear plastic or clear glass pane with scattering particles contained therein.
  • the scattering particles are normally not visible to the eye with transparent or clear materials such as plastic or glass.
  • the milky plastic disc can be made of opaque plastic, for example.
  • the milky plastic pane can also be obtained by a special coating of a surface of a (transparent) plastic pane or by gluing a corresponding film onto a surface of a transparent plastic pane.
  • Milky plastic discs with a light transmission of about 20% to about 70% are preferably used.
  • the scattering particles serve to ensure that the light coupled into the plastic disc is ideally decoupled forward over the surface.
  • a pane from Evonik appears transparent, but when light from a light source, such as an LED light source or a micro-projector, penetrates into it, it is scattered on the particles, as just mentioned.
  • the object is also achieved with a motor vehicle headlight with at least one aforementioned motor vehicle light module.
  • the at least one microprojector is arranged in a (rear) area of a motor vehicle headlight and the at least one projection wall element is designed, for example, as an area of a motor vehicle headlight cover plate.

  • the at least one projection wall element is arranged on a front of the motor vehicle, preferably in a region of a radiator grille of the motor vehicle.
  • the "area of a grille” is understood to mean an area in which the grille is arranged in conventional motor vehicles. However, since the radiator grille no longer exists in the usual form, for example in modern electric motor vehicles, “region of a radiator grille” is understood to mean an area on the motor vehicle front in which the radiator grille would be arranged.
  • Another advantage of the present invention is that the at least one microprojector is not visible from the outside through the downstream projection wall element and is also protected from environmental influences (stone chips, solar radiation, chemicals, etc.).

  • the microprojector 2 is set up to generate a predeterminable light distribution 4 , which is projected onto the at least partially transparent projection wall element 3 in the form of a predeterminable light pattern 5 when the microprojector 2 is switched on. Because the projection screen element 3 is partially translucent, the light distribution 4 forming light on the projection screen element 3 is at least partially scattered. As a result, the predeterminable lighting pattern 5, when the light module 1 is put into operation, is visible on a side 30 of the projection wall element 3 facing away from the microprojector 2.
  • the side 30 of the projection wall element 3 facing away from the microprojector 2 is preferably one side of the projection wall element 3 facing the microprojector 2.
  • the microprojector 2 is designed in such a way that the predeterminable light pattern 5 contains optically represented information. It is understood here that the light distribution 4 generated by the microprojector 2 carries information which is displayed by projecting onto the projection wall element 3.
  • the visibility of the light pattern 5 on the side 30 facing away from the microprojector 2 has the advantage that, for example, a predetermined message can thereby be sent into the surroundings of the light module 1.
  • the projection wall element 3 can be arranged transversely to the optical axis of the light module 1, like this Figures 1 to 5 reveal. However, it is entirely conceivable to arrange the projection wall element inclined to the optical axis, for example to take account of vehicle contours.
  • the at least one projection wall element 3 can be formed, for example, as a transparent layer with a grained surface or, as already mentioned, a milky plastic disc or a plastic disc with scattering particles contained therein.
  • projection wall element 3 should be at least partially translucent so that it can scatter at least part of the incident light forward (for example in the direction of radiation Z).
  • a rough surface can be provided for projection screen elements made of clear materials.

  • the light sources 20 can be arranged in a matrix in an array.
  • the LED light sources can be on a common ( Figure 4 ) or on separate boards ( Figure 5 ) are arranged, which are substantially perpendicular to the radiation direction Z.
  • the projection wall element 3 is preferably arranged essentially perpendicular to the radiation direction Z. However, it is also conceivable to position the projection wall element 3 inclined to the radiation direction Z and thus to produce lighting patterns 5 on obliquely arranged surfaces (projection wall elements). In addition, it is conceivable that the projection screen element has 3 areas in different colors. Furthermore, it is possible to design the projection screen element 3 in a predetermined color. This increases the number of design options even more.
  • the projection device 21 can have one or more projection lenses 210 and one or more apertures 211 assigned to the projection lenses 210.
  • Each projection lens 21 can be, for example, plano-convex or plano-concave or also a free-form lens.
  • Each aperture 211 is preferably assigned at least one projection lens 210.
  • Both the projection lenses 210 and the diaphragms 211 can be arranged in a matrix-like plane, preferably in a plane that is essentially perpendicular to the radiation direction Z.
  • all projection lenses 210 and apertures 211 can each have a single ( Figure 4 ) or several separate ( Figure 5 ) form monolithic structures.

  • each screen 211 has screen edges 212 which have a shape corresponding to the predefinable lighting pattern 5.
  • the diaphragm edges 212 of each diaphragm 211 can form a pattern which corresponds to the entire predefinable lighting pattern 5 ( Figures 1 to 3 ) or only parts of it ( Figure 4 and 5 ) is congruent.
  • the lighting pattern 5 that arises on the projection screen element 3 can thus be predetermined by the shape and course of the diaphragm edges 212 of the at least one diaphragm 212.
  • the light pattern can also be generated on a light conversion element by means of a laser if the light source (s) are laser light source (s) (not shown).
  • each diaphragm 211 can thus form a symbol or a part of the symbol that constitutes information to be displayed.

  • Figure 2 shows an embodiment of the light module 1, in which the aperture 211 is followed by a plurality of projection lenses 210 (a 3 ⁇ 3 array is shown). This makes it possible to better adjust the light intensity within the predeterminable lighting pattern 5 or to make the lighting pattern 5 brighter. Such a configuration is of course in the light modules in the Figures 1 and 3 to 5 possible.
  • the embodiment shown can be expedient if the projection wall element 3 is arranged in the image focal plane of the projection device 21.

Doing so the projection wall element 3 of the projection device 21 in the radiation direction Z at a defined distance, for example from about 10 mm to about 100 mm, preferably from about 25 mm to 50 mm, and thus the light pattern 5 visible on both sides of the projection wall element 3 is generated.
  • the luminous intensity of the luminous pattern 5 can vary depending on the power of the light source, such as an LED light source, and a distance between the microprojector 2 and the projection wall element 3.

  • Such a system can be conceptually combined into a partial micro-projector. If the LED light sources 20 can be controlled separately from one another, then the above-mentioned message can be an entire word, a number, an entire sentence or a lettering. The individual letters of the word can either appear all together or in a predetermined time sequence on the projection wall element 3.
  • FIG. 5 shows a light module 1 which has a plurality of microprojectors 2.
  • Each micro projector 2 can be controlled independently of the other micro projectors 2.
  • each microprojector 2 has a plurality of LED light sources 20 and a plurality of diaphragms 211 with different symbols. If the control of the microprojectors 2 is coordinated with one another, the number of possible different light patterns 5 and thus the number of messages to be sent is increased significantly.
  • the entire message does not have to be generated by the same microprojector 2: one microprojector projects onto the — in this case common — projection wall element 3 the symbol “G”, another one - the symbols “O” and “ >"and a third - the symbol">".
  • the light module 1 of the Figure 5 can be improved by designing each projection lens 210 as a lens array. It is particularly advantageous if each lens in the lens array corresponds to exactly one LED. This enables a particularly sharp image to be produced, since distortions in the edge region of the projection lens 210 are reduced.
  • the projection lens can be configured as a 3x3 lens array - similar to the arrangement of the projection lenses 210 in FIG Figure 4 - Be formed and thus correspond to the arrangement of the individual LEDs on the board, which also form a 3x3 array.
  • FIG. 4 and 5 illustrates that several motor vehicle light modules can be used as building blocks for an overall light module.
  • a modular structure is thus possible, wherein different motor vehicle light modules can have differently designed beam apertures 211.
