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, wherein the at least one microprojector is set up to produce a light distribution, the light distribution being projectable onto the at least one at least partially translucent projection wall element in the form of a predeterminable light pattern.
- 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 as
- Communication element (with the analog environment) can be used.
- 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 for generating light and a projection device, wherein the
- Projection device is arranged downstream of the at least one light source in the radiation direction and is set up to shape the light distribution and to project it onto the at least one at least partially transparent projection wall element.
- the projection device has at least one
- Has 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 luminous 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.
- Projection device a plurality arranged in a matrix in an array
- 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.
- Lens diameter between 1 and 5 mm, preferably 2 mm, preferably at least partially made of glass or silicone, and / or the projection screen element is spaced from the at least one projection lens by about 1 cm to about 10 cm. This results in a very compact motor vehicle light module, which means that it is installed in the
- Headlights and / or in the vehicle front becomes much easier.
- 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.
- 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 usually in the transparent or clear
- the milky plastic disc can be made of opaque plastic, for example.
- the milky plastic disc can also be coated with a special coating
- Scattering particles to ensure that the light coupled into the plastic disc is ideally coupled out evenly over the surfaces to the front.
- a pane from Pirma Evonik appears transparent, but if 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. Furthermore, the object is achieved with a motor vehicle with at least one aforementioned motor vehicle light module.
- 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, for example, the grille no longer exists in the usual form in modern electric motor vehicles, the "area of a grille” is an area on the Understood motor vehicle front, in which the 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.).
- Projection wall element or the like is understood to mean a projection wall element having light-scattering elements, which partly lets the light incident on the projection wall element pass through, partly scatters (in all directions) and partly absorbs. The amount of the scattered light is enough, so that one projected onto the projection screen element
- Light distribution is visible on both sides of the projection screen element (with the naked eye at day and night).
- the light-scattering elements cause that on the
- the partially transparent projection screen element can for example, a milky plastic disc, a transparent disc with a grained surface or a plastic disc with scattering particles contained therein (for example from Evonik).

- FIG. 2 shows an exploded view of a light module with a micro projector with a plurality of projection lenses
- FIG. 3 shows an exploded view of a light module with a microprojector with a collimator
- Fig. 4 is an exploded view of a light module with a micro projector with multiple LED light sources and multiple projection lenses, and
- FIG. 5 shows an exploded view of a light module with a plurality of microprojectors with a plurality of LED light sources.
- FIG. 1 shows a light module 1 which can correspond to the motor vehicle light module according to the invention.
- the light module 1 has a micro projector 2 and an at least partially translucent one
- the microprojector 2 is set up to generate a predeterminable light distribution 4 which is at least partially transparent
- Projection wall element 3 is projected 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 forms light on the
- Projection screen element 3 at least partially scattered. As a result, when the light module 1 is put into operation, the predefinable lighting pattern 5 is on one of the
- Microprojector 2 side 30 of the projection screen element 3 visible.
- 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 that the
- Micro projector 2 generated light distribution 4 carries information that is displayed by projecting onto the projection screen 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. In order to receive this message, it is no longer necessary to choose between the
- the projection wall element 3 can be arranged transversely to the optical axis of the light module 1, as can be seen from pigments 1 to 5. 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, for example, a transparent layer with a grained surface or, as already mentioned, a milky one
- projection screen element 3 should be at least partially translucent so that it forwards at least part of the incident light
- Projection screen elements made of clear materials can be provided with a rough surface.
- the roughness depth can be in the micrometer range and can be, for example, about 5 to 40 micrometers, preferably 10 to 30 micrometers, in particular 20 ⁇ m.
- the projection screen element 3 can be a pane from Evonik, which is made of glass or polymers and has a smooth surface.
- the projection wall element 3 can be a milky disc or a disc with scattering particles contained therein.
- the microprojector 2 can have one or more light sources 20. LED light sources are shown in FIGS. 1 to 5.
- the light source can also be another, for example semiconductor-based, light source, such as a laser light source.
- Microprojector 2 also has a projection device 21, which the
- Light source (s) (20) is arranged downstream in the direction of radiation Z and is set up To shape light distribution 4 and to project this onto the at least one at least partially translucent projection wall element 3.
- the light sources 20 can be arranged in a matrix in an array.
- the LED light sources can be arranged on a common (FIG. 4) or on separate boards (FIG. 5) which are essentially perpendicular to the direction of radiation Z.
- the projection screen element 3 is preferably in the
- 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 diaphragms 211 can each form a single (FIG. 4) or a plurality of separate (FIG. 5) monolithic structures.
- the diaphragm (s) 211 is (are), preferably completely, arranged in a focal plane of the respective projection lens (s) 210.
- each screen 211 has screen edges 212 which have a shape corresponding to the predefinable lighting pattern 5.
- Diaphragm edges 212 of each diaphragm 211 can form a pattern which is congruent with the entire predefinable luminous pattern 5 (FIGS. 1 to 3) or only parts thereof (FIGS. 4 and 5).
- 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).
- the diaphragm edges 212 of each diaphragm 211 can thus form a symbol or a part of the symbol that constitutes information to be displayed.
- the diaphragms 211 can be designed, for example, as metal plates with openings of an appropriate shape or can be printed on one side of a glass or plastic substrate by means of a lithography process. On the opposite side of the glass or plastic substrate
- Projection lenses 210 for example made of silicone, can be applied.
- the glass or plastic substrate serves as a support for projection lenses 210 can and in this case one speaks of a compound lens.
- Orders of a corresponding photoresist or by means of metallizing and lasering can be obtained.
- the symbols can be very different: letters, logos (which makes it possible, for example, to light up a branding of a vehicle manufacturer), signs such as warning signs and so on.
- the projection lenses 210 in the light modules shown in FIGS. 1 to 5 have a lens diameter between 1 and 5 mm, preferably 2 mm, and can at least partially consist of silicone. Furthermore, the projection lenses 210 can contain epoxy resins, acrylates or other plastics or can be formed from these materials.
- the projection screen element 3 can be spaced from the projection lens (s) by approximately 1 cm to approximately 10 cm.
- FIG. 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 possible with the light modules in FIGS. 1 and 3 to 5.
- Projection wall element 3 is arranged in the image focal plane of the projection device 21.
- the image focal plane of the projection device 21 is infinite. 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 produces the lighting pattern 5 visible on both sides of the projection wall element 3.
- 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.
- Pigur 3 reveals that the microprojector 2 can additionally comprise a collimator 22 arranged between the light source 20 and the projection device 21.
- a collimator can also be provided in the microprojectors shown in pigments 1, 2 and 4, 5 and can be arranged downstream of the corresponding light source.
- Pigur 4 shows an example with several LED light sources 20, apertures 211 and
- Projection lenses 210 with each LED light source 20 being assigned exactly one aperture and exactly one projection lens 210.
- 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 all together or in a predetermined time sequence on the
- Projection screen element 3 appears.
- FIG. 5 shows a light module 1 which has a plurality of microprojectors 2.
- 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. It can also be seen from FIG. 5 that the entire message does not have to be generated by the same microprojector 2: a microprojector projects the symbol “G” onto the — in this case common — projection wall element 3, another - the symbols “O” "and">"and a third - the symbol”>".
- the light module 1 of FIG. 5 can be improved in that each projection lens 210 is designed as a lens array.
- 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 designed as a 3x3 lens array - similar to the arrangement of the projection lenses 210 in FIG. 4 - and thus correspond to the arrangement of the individual LEDs on the circuit board, which likewise form a 3x3 array.
- Micro projectors 2 and / or the individual light sources 20 whole logos can be realized.
- Motor vehicle light modules can be used as building blocks for an overall light module.
- a modular structure is thus possible, with different ones
- Motor vehicle light modules can have differently designed beam apertures 211.
- microprojectors 2 and / or light sources 20 or arrays of LED light sources these can be arranged side by side.
- the light modules described above can be used, for example, for design innovations in the main headlight area (luminous logos, lettering, etc.), but also as
- Communication elements can be used, for example, in the field of automated or autonomous driving.
