Description

[0001] The invention relates to a lighting device for a motor vehicle headlight, comprising at least two lighting units arranged next to one another, each lighting unit comprising: at least one light source and a transparent primary optical device associated with the at least one light source, and a transparent secondary optical device, wherein the primary optics device of each lighting unit is configured to direct the light emitted by the at least one light source assigned to it onto the secondary optics device such that at least one light distribution is generated by the secondary optics device of the lighting unit, wherein the lighting device has a holding element which holds the primary optics devices of the lighting units, wherein the holding element is formed from a body made of a transparent material, wherein the body has adjacent receiving through-openings, in each of which a primary optics device is arranged, wherein a primary optics device is attached to at least one boundary surface of the receiving through-opening, which faces an adjacent receiving through-opening, wherein the receiving through-openings are spaced apart from one another.

[0002] Regarding the directional information used, the lighting device is assumed to be arranged horizontally. In this context, "side by side" means "side by side." For a different arrangement, e.g., one rotated by 90°, "side by side" can also be understood as synonymous with "one above the other" or "one below the other."

[0003] Furthermore, the invention relates to a motor vehicle headlight comprising such a lighting device.

[0004] Such lighting devices for motor vehicle headlights or for motor vehicles are known and are used, for example, to generate ADB (glare-free high beam), AFS (curve light in low beam and glare-free high beam mode), or static systems (apron, static high beam), A combined implementation of these lighting functions is also possible.

[0005] To hold the primary optics devices of the two or more lighting units, a holding element is provided that is transparent, in particular translucent and / or light-conducting. This design allows, for example, the primary optics devices and the holding element to be manufactured together in an injection molding process.

[0006] So-called stray light, i.e., light from a light source that is undesirably coupled into the holder via its primary optics, can propagate through total internal reflection within the holder and exit at undesirable locations. For example, light from the light source of a first lighting unit can exit in the area of ​​a second lighting unit and exit into the exterior via the secondary optics of the second lighting unit, which can negatively influence the light distribution generated by the second lighting unit.

[0007] WO 2017 / 054020 A1 discloses a lighting device for motor vehicle headlights.

[0008] It is an object of the invention to prevent or reduce the coupling of light into the holding element.

[0009] This object is achieved with a lighting device mentioned at the outset in that, according to the invention, an overcoupling protection device is arranged in the body between two adjacent receiving through-openings, wherein the overcoupling protection device is formed from a through-opening in the body, wherein the through-opening of the overcoupling protection device is delimited by two side surfaces, which side surfaces face the receiving through-openings in which the primary optics devices are arranged, and wherein at least one of the side surfaces, namely that side surface or those side surfaces whose opposite boundary surface of a receiving through-opening is contacted by the primary optics device arranged in the receiving through-opening, has light deflection means which are designed to deflect at least a part, preferably all of the light beams which emerge from the primary optics device,which faces the side surface and contacts the opposite boundary surface, enter the body and impinge on the side surface, in such a way that this part of the light rays does not enter the adjacent lighting unit or does not impinge on the secondary optical device of the adjacent lighting unit.

[0010] For example, a primary optics device contacts the boundary surface(s) directly, in particular over a large area, or, as described further below, a contact element is provided with which the connection is realized.

[0011] Advantageously, it can be provided that the holding element and the primary optics devices are formed in one piece and preferably consist of the same material.

[0012] It is preferably provided that a primary optics device contacts the holding element at exactly two opposite boundary surfaces.

[0013] In this case, no contact is provided on the upper and lower boundary surfaces of the receiving through-opening, which prevents stray light from being coupled into the holding element via these boundary surfaces.

[0014] In particular, it can be provided that the light deflection means are configured to deflect incident light rays in such a way that the deflected light beam has a larger up / down component (z-component) than the incident light beam, and / or the light deflection means are configured to deflect incident light rays counter to a light emission direction of the respective lighting unit).

[0015] The directional information refers to an assumed horizontal arrangement of the lighting device, as described above. If the arrangement is rotated relative to this assumed arrangement, the directions naturally change accordingly. For example, if the arrangement is rotated 90°, the up / down components become left / right components.

[0016] Light rays are thus deflected more strongly upwards or downwards and either propagate in the holding element or emerge from it, directed so far up or down and upwards / downwards that they do not hit the secondary optics or fundamentally do not enter the adjacent lighting unit.

[0017] It is particularly preferably provided that the light deflection means comprise one or more light deflection surfaces which deflect the incident light rays in such a way that these light rays do not enter the adjacent lighting unit or do not impinge on a region of the secondary optical device which is assigned to an adjacent lighting unit.

[0018] Particularly preferably, the light rays are generally deflected in such a way that they are not deflected forward, so that they cannot reach the secondary optics of the adjacent secondary optics device.

[0019] It can be provided that the primary optical devices of the at least two lighting units each have a main light emission direction, wherein, for example, the main light emission directions are aligned substantially in the same direction, in particular parallel to one another.

[0020] It can be provided that the side surfaces of the overcoupling protection device each run parallel to a main light emission direction of the primary optics device of the adjacent lighting unit.

[0021] It may be provided that the side surfaces of the overcoupling protection device run vertically.

[0022] For example, it can be provided that the light deflection means are designed in the form of a grain or comprise grooves or are designed in the form of grooves, wherein the grooves preferably extend in a horizontal direction, in particular in the direction of a main light emission direction of the primary optical device of the adjacent lighting unit.

[0023] For example, the grooves are straight grooves, thus extending along a straight longitudinal direction, and preferably adjacent grooves are parallel to each other.

[0024] The grooves can be formed in a cross-section, in particular in a cross-section normal to their longitudinal direction, e.g. triangular, in the form of a partial or semicircle, prismatic, rounded, etc.

[0025] Furthermore, it can be provided that at least one of the primary optical devices, preferably each primary optical device, comprises one or more projection optical elements, wherein, if there are two or more projection optical elements, these are preferably arranged in at least one row.

[0026] Each of these projection optics elements can be designed as a separate projection lens.

[0027] Each projection optics element can generate its own part of the light distribution of the lighting unit, e.g. a light segment.

[0028] The projection elements can be directly adjacent to one another and are preferably firmly connected to one another, in particular formed in one piece, particularly preferably from the same material.

[0029] The rows run horizontally and transversely, in particular at 90° to the light emission direction X1, X2 of the respective lighting unit.

[0030] The projection optics device is connected to the holding element using at least one external projection optics element.

[0031] Furthermore, it can advantageously be provided that the at least one primary optics device contacts the at least one boundary surface via a wedge-shaped contact element which is arranged between the boundary surface and the primary optics device, and wherein a narrower wedge surface of the contact element contacts the primary optics device and an opposite, wider wedge surface contacts the boundary surface.

[0032] The contact element is preferably formed from the same material as the holding element and the primary optics device; preferably, the holding element, contact element, and primary optics device are formed integrally with one another.

[0033] The use of such a contact element also contributes to the reduction of stray light, since in this way the size of the area with which the projection optics device is connected to the holder can be kept small, so that the possibilities of light transfer are low, while at the same time a good stability of the connection can be ensured.

[0034] The contact element or the contact elements can be designed, in particular geometrically, in such a way that light is deflected backwards, ie in a direction away from the secondary optical devices and / or can be designed, in particular geometrically, in such a way that light is prevented from being coupled out of the contact element / the contact elements.

[0035] It can be provided that at least the light source of a lighting unit, in particular of each lighting unit, is designed as an LED or of the light-emitting diode type, and wherein, if several light sources are provided, these are preferably arranged in one or more rows.

[0036] The rows of light sources are assigned to the rows of the primary optics device, for example, in such a way that at least one light source / LED, preferably exactly one light source (LED), is assigned to each projection optics element, wherein the assigned light sources / LED are preferably assigned exclusively to this one projection optics element.

[0037] The light sources of a lighting unit can preferably be controlled independently of those of other lighting units.

[0038] Preferably, the light sources of a lighting unit can be controlled independently of the other light sources of this lighting unit, or groups of light sources of a lighting unit can be controlled by other groups of light sources of the lighting unit.

[0039] The primary optical elements are, for example, lenses, in particular biconvex lenses.

[0040] The light sources, in particular LEDs, are preferably each located - viewed in the direction of light propagation - in front of a focal point of their primary optical element and are imaged in an enlarged manner, the image of the light source being in particular a virtual image.

[0041] The secondary optical devices are preferably arranged such that their focal point is generated substantially in the magnified image of the light source, in particular LED, formed by the primary optical element - in particular virtual image.

[0042] For example, the secondary optics devices are projection optics.

[0043] It can be provided that the at least one projection optical device or projection optical elements of the at least one projection optical device are biconvex.

[0044] It has been found that this design offers additional protection against scattering, since when light enters the optical device through the convex entrance surface, a bundled light beam enters the optical device, so that it can no longer couple so strongly into neighboring optics.

[0045] It is advantageous if the secondary optics devices are designed as a secondary optics device component.

[0046] The secondary optical devices are thus realized in a single component, which has different optically effective areas (= secondary optical devices), preferably (exactly) one per lighting unit.

[0047] Furthermore, it can be provided that a diaphragm, in particular a wall-shaped diaphragm, is arranged between at least two lighting units, which extends from the holding element to the secondary optical devices.

[0048] The panel or the plurality of panels and the holding element preferably have an upper and a lower part which can be plugged together one above the other.

[0049] For example, a diaphragm rests against the holding element (100) so that no light from the lighting unit can enter adjacent lighting units via a distance between the diaphragms and the holding elements.

[0050] The one or more diaphragms run approximately parallel to the main light emission direction of an adjacent lighting unit or parallel to the angle bisector of the main light emission directions of the two adjacent lighting units.

[0051] The one or more panels are in particular flat and run essentially vertically.

[0052] The invention is explained in more detail below with reference to the drawing, which shows Fig. 1a lighting device according to the invention in a perspective view obliquely from the front, Fig. 2 the holding element Figure 1 in a front view, Fig. 3 a section of the holding element Figure 2 in a slightly rotated position, Fig. 4 the section from Figure 3 in a horizontal section, Fig. 5 again the section Figure 3 , in a front view, Fig. 6 a horizontal section through the holding element in the area of ​​an overcoupling protection device, and Fig. 7 a view of the retaining element in the area of ​​the overcoupling protection device in a front view.

[0053] In the following, the structure of an exemplary lighting device 100 according to the invention is first described with reference to the Figure 1 - 5 explained in more detail.

[0054] The lighting device 1 comprises at least two, in the specific example four, lighting units 10, 20 arranged next to one another. Each lighting unit 10, 20 comprises at least one light source 11, 21 ( Figure 4 ), a transparent primary optical device 12, 22 associated with the at least one light source 11, 21, and a transparent secondary optical device 31, 32.

[0055] In the example shown, the primary optics devices 12 each comprise precisely one primary optics element 12a, while the primary optics devices 22 each comprise a plurality of primary optics elements 22a arranged side by side in a horizontal row. Preferably, the four primary optics devices 12, 22 are also arranged in a row.

[0056] The rows run horizontally and transversely, in particular at 90° to a (main) light emission direction X1, X2 of the respective lighting unit 10, 20.

[0057] Each of these primary optical elements 12a, 22a can be designed as a separate projection lens.

[0058] It can be provided that the primary optical elements 12a, 22a are biconvex.

[0059] The light sources 11, 21 are preferably designed as LEDs, with each primary optical element 12a, 22a preferably being assigned its own LED 11, 21. Each LED 11, 21, together with its primary optical element 12a, 22a, can generate an image of the light source, in particular an enlarged image, for example in the form of a light segment.

[0060] The primary optical elements can be directly adjacent to one another and are preferably firmly connected to one another, in particular formed in one piece, particularly preferably from the same material.

[0061] The light sources of a lighting unit can preferably be controlled independently of those of other lighting units.

[0062] Preferably, the light sources of a lighting unit can be controlled independently of the other light sources of this lighting unit, or groups of light sources of a lighting unit can be controlled by other groups of light sources of the lighting unit.

[0063] The light sources, in particular LEDs, are preferably each located - viewed in the direction of light propagation - in front of a focal point of their primary optical element and are imaged in an enlarged manner, the image of the light source being in particular a virtual image.

[0064] The secondary optical devices are preferably arranged such that their focal point is generated substantially in the magnified image of the light source, in particular LED, formed by the primary optical element - in particular virtual image.

[0065] For example, the secondary optics devices are projection optics.

[0066] In the example shown, the secondary optics devices 31, 32 are designed as a secondary optics device component 30. The secondary optics devices 31, 32 are thus realized in a single component, which has different optically effective regions (= secondary optics devices), preferably one per illumination unit.

[0067] The primary optics device 11, 22 of each lighting unit 10, 20 is configured to direct the light emitted by the light sources 11, 21 assigned to it onto the secondary optics device 31, 32 in such a way that at least one light distribution is generated by the secondary optics device 31, 32 of the lighting unit 10, 20. For example, the light emitted by a light source onto a primary optics element is imaged by the primary optics element together with the assigned secondary optics device in the far field, i.e., e.g., on a road, as a (partial) light distribution. All light sources of a lighting unit together thus form an (overall) light distribution.

[0068] Examples of such light distributions or the corresponding light functions are ADB (glare-free high beam), AFS (cornering light in low beam and glare-free high beam operation), or static systems (apron, static high beam).

[0069] The lighting device 1 further comprises a holding element 100, which holds the primary optics devices 12, 22 of the lighting units 10, 20. The holding element 100 is formed from a body 110 made of a transparent material, wherein the body 110 has adjacent receiving through-openings 101, 102, in each of which a primary optics device 12, 22 is arranged.

[0070] Preferably, the holding element 100 and the primary optics devices 12, 22 are formed in one piece and preferably consist of the same material.

[0071] Each primary optic device 12, 22 is connected to at least one boundary surface 101a, 101b, 102a, 102b of the receiving through-opening 101, 102, in particular a lateral boundary surface. Preferably, each primary optic device 12, 22 is connected to two, preferably lateral, opposing boundary surfaces; in this specific example, the primary optic device 22 is connected to the boundary surfaces 102a, 102b, and the primary optic device 12 is connected to the boundary surfaces 101a, 101b. The primary optic devices are each spaced apart from the upper and lower boundary surfaces. In a primary optic device 22 with multiple primary optic elements 22a, the connection to the holding element is preferably made to at least one or the outer primary optic element(s).

[0072] In order to enable a stable connection, a contact area between the primary optics device and the boundary surface has a certain extent / area through which light can enter the holder and enter, for example, an adjacent lighting unit as unwanted scattered light.

[0073] Thus, in the example shown, light from the projection optical device 12 of the illumination unit 10 can enter the holding element 100 or the body 110 via the boundary surface 101a of the receiving through-opening 101 and could thus enter the adjacent illumination unit 20 as unwanted scattered light.

[0074] Likewise, light from the projection optics device 22 of the illumination unit 20 could enter the holding element 100 or the body 110 via the boundary surface 102b of the receiving through-opening 102 and could thus enter the adjacent illumination unit 10 as unwanted scattered light.

[0075] According to the invention, an overcoupling protection device 200 is therefore arranged in the body 110, between the two adjacent receiving through-openings 101, 102, wherein the overcoupling protection device 200 is formed from a through-opening 201 in the body 110, wherein the through-opening 201 of the overcoupling protection device 200 is delimited by two side surfaces 211, 212, which side surfaces 211, 212 face the receiving through-openings 12, 22 in which the primary optical devices 12, 22 are arranged.

[0076] The side surfaces 211, 212 have light deflection means 220, 230 which are designed to deflect at least a part, preferably all of the light rays which enter the body 110 from a primary optical device 12, 22, which faces the side surface 211, 212 and contacts the boundary surface 101b, 102a opposite the side surface 211, 212, and which impinge on the side surface 211, 212, in such a way that this part of the light rays does not enter the adjacent lighting unit 10, 20 or does not impinge on the secondary optical device 31, 32 of the adjacent lighting unit 10, 20.

[0077] How Figure 7 can be removed, it is advantageously provided that the light deflection means 220, 230 are designed to deflect incident light beams in such a way that the deflected light beam has a larger up / down component (z-component) than the incident light beam.

[0078] Light rays are thus deflected more strongly upwards or downwards and either propagate in the holding element or emerge from it, directed so far up or down and upwards / downwards that they do not hit the secondary optics or fundamentally do not enter the adjacent lighting unit.

[0079] Alternatively or preferably additionally, it is advantageously provided that the light deflection means 220, 230 are designed to deflect incident light rays counter to the light emission direction X1, X2 of the respective lighting unit 10, 20 ( Figure 6 ).

[0080] In particular, it can be provided that the light deflection means 220, 230 comprise one or more light deflection surfaces 221, 231, which deflect the incident light rays in such a way that these light rays do not enter the adjacent lighting unit 10, 20 or do not impinge on a region of the secondary optical device 31, 32 which is assigned to an adjacent lighting unit 10, 20, and preferably have a deflection behavior of the light rays impinging on the side surfaces 211, 212 as described above.

[0081] The side surfaces 211, 212 of the overcoupling protection device 200 are, for example, vertical and are each parallel to the main light emission direction X1, X2 of the primary optics device 12, 22 of the adjacent lighting unit 10, 20.

[0082] For example, the side surfaces 211, 212 of the overcoupling protection device 200 are formed as basically flat surfaces on which the light deflecting means 220, 230 are formed, so that the resulting side surface deviates from the flat shape.

[0083] For example, it can be provided that the light deflection means 220, 230 comprise grooves or are formed in the form of grooves in the base area, wherein the grooves preferably extend in the horizontal direction, in particular parallel to the main light emission direction X1, X2 of the primary optics device 12, 22 of the adjacent lighting unit 10, 20.

[0084] As can be seen in the figures, the primary optics device 22 is directly connected to the boundary surface 102b, ie the outermost primary optics element 22a is directly connected to the boundary surface 102b.

[0085] The primary optics device 12, however, is not directly connected to the boundary surface 101a; rather, it is connected to the boundary surface 101a via a wedge-shaped contact element 240a. In this example, the primary optics device 12 is connected to the second lateral boundary surface 101b in addition to a second such contact element 240b.

[0086] A narrower wedge surface of the contact element contacts the primary optics device 12, while an opposite, wider wedge surface contacts the boundary surface 102a. ( Figure 6 )

[0087] The contact element is preferably formed from the same material as the holding element and the primary optics device; preferably, the holding element, contact element, and primary optics device are formed integrally with one another.

[0088] In this context, it should be noted that in the case of a one-piece design, in particular made of the same material, there is no boundary surface in the actual, material sense and this is an imaginary surface.

[0089] The use of such a contact element also contributes to the reduction of stray light, since in this way the size of the area with which the projection optics device is connected to the holder can be kept small

[0090] Finally, it can be seen that, for example, a diaphragm, in particular a wall-shaped diaphragm 300, is arranged between each two lighting units 10, 20, which extends from the holding element 100 to the secondary optical devices 31, 32.

[0091] The panel 300 or the plurality of panels 300 and the holding element 100 preferably have an upper and a lower part, which can be plugged together one above the other.

[0092] For example, the aperture rests against the holding element 100 so that no light from the lighting unit can enter adjacent lighting units via a distance between the aperture and the holding elements.

[0093] The one or more diaphragms run approximately parallel to the main light emission direction of an adjacent lighting unit or parallel to the angle bisector of the main light emission directions of the two adjacent lighting units.

[0094] The one or more panels are in particular flat and run essentially vertically.
