Furthermore, the invention relates to a motor vehicle headlight with at least one such light module.

Light modules of the above type are known from the prior art. The international application of the Applicant WO 2015/058227 A1 shows a microprojection light module for a motor vehicle headlamp comprising at least one light source and at least one projection device which images the light emerging from the at least one light source in an area in front of the motor vehicle in the form of at least one light distribution, wherein the projection device comprises: an entrance optics, which consists of an array of micro-entry optics; an exit optics, which consists of an array of micro-exit optics, each micro-entry optics is associated with exactly one micro-exit optics, wherein the micro-entry optics are formed and / or the micro-entry optics and the micro-exit optics are arranged to each other, that the light emerging from a micro-entry optics enters exactly into the associated micro-exit optics, and wherein the light preformed by the micro-entry optics is imaged by the micro exit optics in an area in front of the motor vehicle as at least one light distribution.

In the international application WO 2017/066817 A1 the applicant is a microprojection light module for a vehicle headlight thematized, which comprises at least one light source and at least one projection device, which the light emerging from the at least one light source in an area in front of the motor vehicle in the form of at least one light distribution, wherein the projection device has an entrance optics, which has one, two or more micro-entry optics, which are preferably arranged in an array, and an exit optics comprising one, two or more micro-exit optics, which are preferably arranged in an array, each micro-entry optics being associated with exactly one micro-exit optic, the micro-entry optics being formed and / or the micro-entry optics and the micro Egress optics are arranged to each other such that substantially all of the light emerging from a micro-entry optic light enters exactly only in the associated micro-exit optics, and wherein the preformed by the micro-entry optics light from the micro-exit optics in an area in front of the motor vehicle as at least one Lichtverteilun g is displayed.

Further shows the international application WO 2017/066818 A1 the applicant a microprojection light module for a motor vehicle headlamp, comprising at least one light source and at least one projection device which images the light emerging from the at least one light source in an area in front of the motor vehicle in the form of at least one light distribution, wherein the projection device comprises an entrance optics, which one, two or more micro-entrance optics, which are preferably arranged in an array, an exit optics having one, two or more micro-exit optics, which are preferably arranged in an array, each micro-entry optics exactly one micro-exit optics is assigned, wherein the micro-entrance optics formed in such a way and / or the micro-entry optics and the micro-exit optics are arranged to each other such that substantially all of the light emerging from a micro-entry optics light only in the associated micro-exit optics wherein the light preformed by the micro-entry optics is imaged by the micro-exit optics in an area in front of the motor vehicle as at least one light distribution, wherein a first diaphragm device is arranged between the entrance optics and the exit optics.

A disadvantage of the above-mentioned light modules is that only a very limited number of light distributions can be generated with a single light module, and consequently light functions can be realized (low efficiency). Above all, it is disadvantageous that such light modules offer no possibility of the same light exit surface of the light module a secondary light function, such as direction indicator (static or dynamic, for example as running light), position light and / or daytime running lights (static or as running light), etc. and a main light function, such as low beam, high beam, light functions of an adaptive front light system (light functions of an AFS headlamp ) to realize.

The object of the present invention is to improve the conventional light modules to the effect, or to expand their structure so that from the light exit surface of the same light module several light functions, preferably can be generated simultaneously.

The object is achieved with a light module of the type mentioned above in that at least one additional light source - so-called additional light source - is provided, which is arranged at least one additional light source to emit light between the entrance optics and the exit optics (in this area there the at least one additional light source emits light); the exit optics is set up to image the light emitted by the at least one additional light source into the area in front of the light module in the form of a light distribution of a second predetermined type; the entrance optics and the at least one additional light source are designed and assigned to one another such that neither the at least one additional light source nor the light emitted by the at least one additional light source alters the intermediate image.

In this case, the light generated by the at least one additional light source does not influence the intermediate image produced with the light of the at least one light source. Preferably, the at least one additional light source generates in the intermediate image plane an additional / second intermediate image which does not overlap the (original, generated with the light of the at least one light source) intermediate image.

It is conceivable that the at least one light source is downstream of a collimator.

As a result, it can be achieved, for example, that the light distribution of the first predetermined type does not overlap the light distribution of the second predetermined type in the light image, although it is emitted from the same light exit surface of the light module become. Such light distributions can be used to realize different light functions.

For example, the entrance optics and the at least one additional light source can be designed and assigned to each other such that the light generated by the at least one light source according to (or along) a first and the light generated by the at least one additional light source according to a second, different beam path passes through the optical projection device. It is expedient if the at least one additional light source is outside the first beam path - ie not in the first beam path - so that neither the at least one additional light source nor the light emitted by the at least one additional light source changes the intermediate image.

It may be expedient if the at least one additional light source is set up to produce collimated light which is substantially parallel to the optical axis of the projection device. This has the advantage that with respect to a light image generated with the at least one additional light source, an exact position of the at least one additional light source between the entrance optics and the exit optics and in particular with respect to the intermediate image plane is not relevant, whereby the adjustment of the light module is easier. It may even be advantageous if the at least one additional light source is not arranged in the intermediate image plane.

Further advantages result if the inlet optics and the exit optics are embodied as matrix-like arrays of micro entrance optics or micro exit optics-micro entrance optics array and micro exit optics array, respectively, which are arranged transversely to the optical axis of the optical projection device. wherein each micro-entry optics at least one, preferably exactly one micro-exit optics corresponds such that they have a common, preferably horizontally extending, optical axis and form a micro-optical system.

In the context of the present invention, the term "common optical axis of two optics" means that the optical axes of these two optics substantially coincide.

Using very small optics at the light exit surface - micro-optics with characteristic sizes in the micrometer range - leads to a more uniform appearance of the light-emitting surface in both unlighted and illuminated state.

It can further be provided that the at least one additional light source has a plurality of spaced-apart Lichtabstrahlbereiche for emitting the light between the entrance optics and the exit optics, which Lichtabstrahlbereiche in a substantially transverse to the optical axis of the projection device level - in the so-called Lichtabstrahlebene - are arranged. It is understood that this plane is arranged between the entrance optics and the exit optics. Preferably, by means of each light emission region, a light beam is generated which propagates parallel to the optical axis of the projection device.

In addition, it may be provided that the at least one additional light source has a light guide element and a light source associated with the light guide element, preferably an LED light source, wherein the Lichtabstrahlbereiche are arranged in the light guide element. It may be advantageous if the light source is not between the entrance optics and the exit optics. In a practical embodiment, it can be provided that the luminous means and the at least one light source are arranged on a common light source carrier. For example, if the at least one light source and the lighting means are designed as LED light sources, these LED light sources can be arranged on a common printed circuit board (on the same print).

Furthermore, it can be provided that the light guide element is formed as a light guide plate arranged substantially transversely to the optical axis of the projection device, wherein the light guide plate at least one light input surface for coupling light of the light source, which propagates light in the light guide plate and at the Lichtabstrahlbereichen from the Light guide plate exits. It is known that the propagation of light within a light guide occurs due to total reflection. The light of the light source can be coupled laterally or from below or from above into the light guide plate. After coupling, the light propagates (due to total reflection) in the direction of the area between the entrance optics and the exit optics. In the area between the entrance optics and the exit optics, the light spreads in the area Light guide plate substantially transversely to the optical axis of the projection device until it is deflected in the Lichtabstrahlbereichen and emerges in a direction substantially parallel to the optical axis direction of the light guide plate.

In the context of the present invention, the term "light guide plate" is understood to mean a plane light guide element extending in a plane in two directions.

It may be expedient if each Lichtabstrahlbereich has a plurality of Lichtauskoppelprismen. In this case, the light extraction prisms are preferably configured to couple out the light from the light guide plate in a direction substantially parallel to the optical axis. The light extraction prisms are perpendicular to the propagation direction of the light in the light guide plate. For example, the light extraction prisms on an angle of about 40 °.

Feeding (injecting) from different sides into the light guide plate and matching the shape of the light extraction prisms may help to realize even more (more than two) different light functions.

In an advantageous embodiment, provision can be made for the micro-entry optical array to have a plurality of intermediate regions assigned to the light emission regions and preferably planar.

The micro-optics of the micro-entrance optics array and / or the micro-exit optics array may be formed, for example, as convex lenses.

The intermediate regions of the micro-entrance optical array preferably have no micro-entry optics and, for example, are designed such that scattering is reduced by the light generated by means of the at least one light source. If the at least one light source generates parallel light or the light of the at least one light source is collimated, for example, by a collimator, it is more likely to encounter the entrance optics, it is particularly advantageous to form the intermediate regions in a planar manner.

In this sense, the light penetrating into the projection device through these intermediate regions is irrelevant to the formation of the intermediate image and thus to the first light function. Preferably, this light can be shielded (see below).

It can be provided with advantage that the Lichtabstrahlbereiche are distributed checkerboard in the Lichtabstrahlebene and the intermediate areas in the micro-entrance optics array are distributed like a checkerboard, wherein the Lichtabstrahlbereiche the intermediate areas (in the direction of the optical axis) are arranged downstream. This means, for example, that this arrangement is a checkerboard pattern formed preferably in the direction of the optical axis of the optical projection device, preferably of squares. In this case, it is expedient for the areas of the checkerboard pattern comprising areas of the checkerboard pattern which comprise light-emitting areas to be arranged corresponding to the intermediate areas of the checkerboard pattern.

In addition, it may be expedient if the intermediate regions are made opaque. In addition, a shielding element may be provided with the intermediate regions of corresponding opaque shielding regions, which shielding element shields the intermediate regions from the light of the at least one light source.

Moreover, it may be advantageous if the at least one additional light source is designed as a carrier for the entrance optics or the exit optics. Preferably, the entrance optics or the exit optics, which are for example as the micro entrance optics array or the micro exit optics array of silicone, arranged on the additional light source, for example, applied to them, in particular connected to this, for example glued. This is particularly advantageous with regard to the synergetic use of photometrically relevant components of a light module (for example, if the substrate plate is used as a light guide).

The entry optics, in particular the micro entrance optics array, are preferably arranged, for example applied, in particular glued, on a side of the at least one additional light source facing the at least one first light source.

The variety of light functions that can be realized with the light module according to the invention can be further increased if two additional light sources are provided, wherein a first of the two additional light sources carries the entrance optics and a second of the two additional light sources carries the exit optics.

The exit optics, in particular the micro exit optics array, are preferably arranged, for example applied, in particular glued, on a side of the second additional light source facing away from the at least one first light source.

Furthermore, it can be advantageous if the light emission regions of the first additional light source and the light emission regions of the second additional light source are designed and positioned relative to one another such that light rays generated by the corresponding light emission regions propagate in different, non-overlapping regions of the projection device. In this case, the light emission regions of the at least one or all additional light sources can be placed in the unimportant regions emitted by the at least one light source, which emits, for example, light for the main light function. This will not affect the main light function.

In addition, it can be provided that the projection device has at least one aperture device located between the entrance optics and the exit optics, which has at least one aperture device apertures corresponding to the intermediate regions and is adapted to form the intermediate image (for example for a low-beam light distribution) and / or optical aberrations correct.

In a further preferred embodiment, a first diaphragm element can be provided, which first diaphragm element is disposed in front of the light emission regions and shields the light emission regions from the light of the at least one light source.

It may be expedient if the first diaphragm element is set up to form the intermediate image from the light emitted by the at least one light source, for example for a low-beam light distribution.

Furthermore, it may be expedient if the Lichtabstrahlbereiche in the Lichtabstrahebene the at least one additional light source has a shape horizontally, transversely to the optical axis of the optical projection device extending vertically from each other, preferably equidistant spaced strips and the panel element has these strips corresponding opaque areas.

The aperture element can be arranged, for example, on the light exit side with respect to the entrance optics and in front of the light guide plate, for example on a light exit surface of the entrance optics or on a side of the light guide plate facing the at least one light source, in particular on the light exit surface of the entrance optics or on the side of the light guide plate facing the at least one light source be upset.

Moreover, it may be advantageous if the at least one additional light source is designed as a carrier for at least the first diaphragm element. Preferably, the first panel element is arranged on the at least one additional light source, for example applied to it, in particular printed on this.

Preferably, the first diaphragm element is arranged on one of the at least one light source side facing the at least one additional light source, for example applied, in particular glued.

Further advantages are obtained if two additional light sources are provided, wherein a first additional light source carries at least the first diaphragm element, a second additional light source carries the exit optics and the first diaphragm element is disposed in front of the light emission regions of the first additional light source. Preferably, the exit optics, in particular the micro exit optics array is arranged on one of the at least one light source side facing away from the second of the second additional light source, for example applied, in particular glued.

In addition, it may be advantageous if the Lichtabstrahlbereiche the first additional light source and the Lichtabstrahlbereiche the second additional light source are designed and positioned to each other such that propagate from the corresponding Lichtabstrahlbereichen light beams propagate in different non-overlapping areas of the projection device.

In addition, a second diaphragm element may be provided, which second diaphragm element is disposed in front of the light emission regions of the second additional light source and arranged to shield the second additional light source and / or to limit light emitted by the first additional light source. As a result, by means of the second diaphragm element scattered light quantity can be reduced and / or aberrations can be reduced.

Moreover, in view of the compact design of the projection device, it may be advantageous if the first additional light source is designed as a carrier for the second diaphragm element. Preferably, the second diaphragm element is arranged on the first additional light source, for example applied to it, in particular printed on it.

Preferably, the second diaphragm element is arranged on one of the at least one light source side facing away from the first additional light source, for example applied, in particular glued.

It may be useful if the light distribution of the first predetermined type completes the light distribution of the second predetermined type to a total light distribution or the light distribution of the first predetermined type is independent of the light distribution of the second predetermined type.

In this case, it means independently that the light distribution of the second type can be generated independently of whether the light distribution of the first type is being generated or not. For example, daytime running lights can be on - are generated with the light generated by means of at least one additional light source, without causing a Abblendlichtverteilung is emitted - the at least one light source is off.

As already mentioned, the first predetermined type of light distribution may be a main light function light distribution, for example, low beam distribution or high beam distribution. Here, the second predetermined type of light distribution may be a sub-light function light distribution, for example, a turn signal light distribution, position light light distribution, daytime running light light distribution, signlight light distribution. In this case, at least one main and at least one secondary light function For example, be realized simultaneously or corresponding light distributions are generated simultaneously.

The light distributions of the first and second types may overlap each other (when both are generated). However, it may also be advantageous if the light distribution of the second type does not overlap the light distribution of the first type in the light image (for example low beam distribution with Signlight light distribution).

Depending on the advantageous embodiment, the present invention can bring one or more of the following advantages: multiple light functions from the same light exit surface possible; less installation space than with separate version (several independent light modules) necessary; Homogeneous appearance in the illuminated / unlit state; Light emission areas are imaged by lens optics, which allows a better design of the light distribution and thus light utilization.

To improve readability, each figure is provided with a coordinate system. Three directions are indicated: horizontal H and vertical V direction and a main emission direction Z of the motor vehicle light module.

The terms "above", "below", "vertical", "horizontal" etc. refer to a professional installation position of the motor vehicle light module in a motor vehicle. For example, the main emission direction Z corresponds to the forward movement direction of the motor vehicle when the motor vehicle light module is arranged in a motor vehicle headlight for generating at least one main light distribution.

First, it will open Figures 1, 1a and 2 Reference is made to those parts and aspects of a motor vehicle light module, which apply equally to the first and the second embodiment. Figures 1, 1a and 2 each shows a schematic representation of a motor vehicle light module (or a part of the motor vehicle light module) for a headlight, in particular motor vehicle headlight, which may correspond to a light module according to the invention. Such a motor vehicle light module is particularly well suited for motor vehicle headlights, in which a compact design is in the foreground and from a single and preferably continuous light exit surface several light functions (for example, a main and at least one secondary light function) should preferably be realized simultaneously. In the context of the present invention, this light exit surface corresponds to a light exit surface of an exit optics 22 of at least one projection device 2 (see also FIG FIGS. 1 to 15 ). In addition to the at least one projection device 2 with the exit optics 22, the motor vehicle light module has at least one light source 1 , for example an LED light source. Preferably, the at least one light source 1 is preceded by a collimator 9 . The projection device 2 also has an entrance optics 21 . In this case, the entry optics 21 and the exit optics 22 are arranged, an intermediate image of light emitted by the at least one light source 1, preferably collimated by the collimator 9 in a light lying between the entrance optics 21 and the exit optics 22, substantially transverse to an optical axis of the projection device 2 standing intermediate image plane to form. The exit optics 22 is set up to image the intermediate image in the form of a light distribution of a first predetermined type into an area in front of the motor vehicle light module. The first type of light distribution may be, for example, a main light function light distribution - ie a light distribution which is generated when the main light function of the motor vehicle light module is activated. In particular, a main light function light distribution may be a low beam distribution or (for example, adaptive or glare-free) high beam distribution.

In addition, at least one additional light source - so-called additional light source 3a, 3c - is provided, which at least one second additional light source 3a, 3c is arranged to emit light between the entrance optics 21 and the exit optics 22. This indicates a location or a region at which the at least one additional light source emits light (produced by it). Like that Figures 1, 1a and 2 can already be seen, the at least one additional light source 3a, 3c is preferably not a point light source. It is advantageous if the at least one additional light source 3a, 3c extends spatially and occupies a predetermined area between the entrance optics 21 and the exit optics of the projection device. In this case, as can be seen from the examples described below, the at least one additional light source 3a, 3b , 3c, 3d (see also FIG FIGS. 7 to 15 ) comprise a luminous means 32 which lies outside the region between the entrance optics 21 and the exit optics 22.

The light emitted by the at least one additional light source 3a, 3b is imaged by means of the exit optics 22 in the (same) area in front of the light module in the form of a light distribution of a second predetermined type. Preferably, the second type of light distribution is a secondary light function light distribution - ie a light distribution which is generated when the secondary light function of the motor vehicle light module is actuated. In particular, a sub-light function light distribution, a daytime running light distribution, position light light distribution, turn signal light distribution, Signlight light distribution or the like, such as signal light running light, especially turn signal running light possible (also position light-light distribution, daytime running light distribution as running light possible ). In addition, logos, welcome light functions can be realized.

In this case, the entrance optics 21 and the at least one additional light source 3a, 3c are formed and assigned to one another such that neither the at least one additional light source 3a, 3c nor the light emitted by the at least one additional light source 3a, 3c illuminates the intermediate image changes.

The light generated by the at least one additional light source 3a, 3b, 3c, 3d leaves the intermediate image generated with the light of the at least one light source 1 unaffected / unimpaired / unchanged. Preferably, the at least one additional light source 3a, 3c generates in the intermediate image plane an additional / second intermediate image which does not overlap the (original) intermediate image.

The light generated by the at least one light source 1 propagates according to (or along) a first beam path 100 and the light generated by the at least one additional light source 3a, 3b, 3c, 3d according to a second, different beam path 300a , 300b , 300c , 300d through the optical projection device 2 (see in particular FIGS. 7 to 15 ). It is expedient if the at least one additional light source 3a, 3b, 3c, 3d outside of the first beam path 100 - that is not in the first beam path - is.

It is advantageous if the at least one additional light source 3a, 3b, 3c, 3d is set up to produce collimated light, which is substantially parallel to the optical axis of the projection device 2.

For this reason, an exact position of the at least one additional light source 3a, 3b, 3c, 3d between the entrance optics 21 and the exit optics 22 and in particular with regard to the intermediate image plane is not relevant. Nevertheless, it is conceivable to place the at least one additional light source 3a, 3b, 3c, 3d in the intermediate image plane.

It can be advantageous if the entrance optics 21 and the exit optics 22 are arranged as matrix-like arrays of micro entrance optics 210 or micro exit optics 220 - micro entrance optics array or micro exit optics - in planes perpendicular to the optical axis of the optical projection device 2. Array - are formed, each micro-entry optics 210 at least one, preferably exactly one micro-exit optics 220 corresponds such that they have a common, preferably horizontally extending, optical axis and form a micro-optical system. The micro-input / output optics 210, 220 may be formed, for example, as convex lenses. The direction of the optical axis of each micro-optics system preferably coincides with the main emission direction Z.

In the context of the present invention, the term "common optical axis of two optics" means that the optical axes of these two optics substantially coincide.

As already mentioned in the introduction to the description, the person skilled in the art can provide further details on the micro-optics arrays and on the projection devices which are used by means of such Micro-optic arrays can be formed by the Applicant's aforementioned applications WO 2015/058227 A1 ; WO 2017/066817 A1 ; WO 2017/066818 A1 remove.

Furthermore, it may be advantageous for the at least one additional light source 3a, 3b, 3c, 3d to have a plurality of spaced light emission regions 30a, 30b, 30c, 30d for emitting the light between the entrance optics 21 and the exit optics 22 (see in particular FIG FIGS. 9 to 15 ), which Lichtabstrahlbereiche 30a, 30b, 30c, 30d in a plane substantially transverse to the optical axis of the projection device 2 - in the so-called Lichtabstrahlebene are arranged. On the basis of the above, it is understood that this plane is arranged between the entrance optics 21 and the exit optics 22. Preferably, by means of each light emission region, a light bundle 300a, 300b, 300c, 300d is generated, which propagates parallel to the optical axis of the projection device 2.

It is advantageous if the Lichtabstrahlbereiche 30a, 30b, 30c, 30d of the exit optics 22 are assigned. It is particularly advantageous if each light emission area of a region of the exit optics 22, for example one - if the exit optics is designed as a micro exit optics array - is associated with individual micro exit optics 210 or a horizontal row of the micro exit optics. In conventional, for example, linear light guides / luminaires, the decoupling element is located on the rear side of the luminous element (with respect to the emission direction Z). The deflected by the coupling element light exits at the opposite side by a curved exit surface of the filament. In this case, as is known from the prior art, it is possible to influence the emission characteristic of the luminous element by shaping that region of the exit surface at which the light leaves the luminous element. The abovementioned assignment of the light emission regions 30a, 30b, 30c, 30d of the exit optics 22 can serve, for example, for the curvature of the exit optics 22, for example their micro exit optics 210, to be shaped by the at least one additional light source 3a, 3b, 3c , 3d generated photo is used. The light image can therefore be designed on the one hand via the size and / or shape of the Lichtabstrahlbereiche 30a, 30b, 30c, 30d of the at least one additional light source 3a, 3b, 3c, 3d and / or on the imaging properties of the exit optics 22, such as its thickness or thickness of the micro-exit optics 220 and / or shape of a Light exit surface, for example (local / global) curvature. As a result, the efficiency of the at least one additional light source 3a, 3b, 3c, 3d is increased.

In the Figures 1, 1a and 2 It can be seen that the at least one additional light source 3a, 3c has a light guide element 31a, 31c and the already briefly mentioned light source 32, wherein the light source 32 is associated with the light guide element 31a, 31c. The lighting means 32 is preferably designed as an LED lighting means. Here, the Lichtabstrahlbereiche 30a, 30b, 30c, 30d (in FIGS. 1 and 2 not visible) are preferably arranged in the light guide element 31a, 31b, 31c, 31d. For example, the luminous means 32 does not lie between the entrance optics 21 and the exit optics 22, like the ones shown in FIG Figures 1, 1a and 2 demonstrate. The luminous means 32 can be designed as an LED illuminant. It is quite conceivable that both the LED light source 1 and the LED illuminant 32 are mounted on a common printed circuit board. Furthermore, the LED light source 1 and the LED illuminant 32 can each have a plurality of LEDs, wherein both the LEDs of the LED light source 1 and the LEDs of the LED illuminant 32 are in a plane substantially perpendicular to the optical axis of the projection device 2 are arranged and preferably emit light in the direction of the optical axis. For example, the LED lighting means three side by side (not shown) or one above the other (see FIG. 1a ) arranged LEDs have. An arrangement of the LED illuminant from above / below makes it possible to arrange a plurality of projection devices 2 side by side in a motor vehicle headlight.

The optical waveguide element may be formed as a light guide plate 31a, 31b, 31c, 31d , which (in the region between the entrance optics 21 and the exit optics 22) is arranged substantially transversely to the optical axis of the projection device 2. At this point, a reference to the above-mentioned prior art is appropriate. The international applications WO 2015/058227 A1 . WO 2017/066817 A1 . WO 2017/066818 A1 all show light modules - so-called microprojection light modules - in which micro-entry optics array and micro-exit optics array each applied to a substrate plate, such as a glass plate, in particular glued. The substrate plates are often present because the micro-entry optics or micro-exit optics of the microprojection light modules can already be arranged during production on such a glass carrier / substrate plate. With the help of substrate plates, for example, optical properties, such as focal length, of the lenses (micro-optics) be specified. If a certain focal length is desired, it can be achieved by varying the "thickness" of the substrate plates. The micro-entry optics, micro-exit optics can be made of polycarbonate (PC) and arranged on a substrate plate made of crown glass (for example, B270® glass), for example, be glued. Optical fiber element may be made of polycarbonate, for example. As a result, the thickness, ie the extent in the direction of an optical axis, of the entire projection device is also predetermined. Substrate plates for the micro entrance optics array or micro exit optics array can be different in thickness. This has the same reason: the thickness of the projection device is practically predetermined by the fixed dimensions of the lenses in the micro entrance optics array or micro exit optics array. In addition, in the conventional light modules one or more aperture (s) may be provided, which also on a substrate plate - so-called Shuttersubstrat (shutter - borrowed from the English for aperture) - is (are) applied. In this case, the thickness of the projection device can be reduced in the manufacturing process such that the shutter substrate can be inserted.

It may be advantageously provided that one or more of the light guide plates 31a, 31b, 31c, 31d are formed as a substrate plate of the micro entrance optics array and / or the micro exit optics array or as a shutter substrate.

The light guide plate 31a, 31b, 31c, 31d has at least one, preferably laterally or below or above the light guide plate 31a, 31b, 31c, 31d arranged Lichteinkoppelfläche 310a, 310c for coupling light 320a, 320c of the bulb 32, which light in the light guide plate propagates and exits at the light emitting portions 30a, 30b, 30c, 30d from the light guide plate. Specialist knowledge includes the knowledge that the coupled-in light propagates in a light guide due to total reflection. FIGS. 1 and 2 show light guide plates, which are formed in the region between the entrance optics 21 and the exit optics 22 plan and outside of this region have a bent portion 330 a, 330 c. The light guide plates 31a, 31c shown are preferably bent towards their light coupling surfaces 310a, 310c. As a result, for example, the abovementioned arrangement of the at least one light source 1 and of the luminous means 32 is made possible in a common plane which is essentially perpendicular to the optical axis. The light 320a, 320c emitted by the respective luminous means 32 parallel to the optical axis of the projection device 2 is transmitted via the respective one Illuminant 32 coupled light input surface 310a, 310c coupled into the light guide plate 31a, 31c, propagates due to the total reflection through the bent portion 330a, 330c in the lying between the entrance optics 21 and the exit optics 22 area of the light guide plate 31a, 31c and is at the Lichtabstrahlbereichen 30a, 30b, 30c, 30d are coupled out substantially parallel to the optical axis of the projection device 2.

In the context of the present invention, the term "light guide plate" in the region in which light is coupled out of the light guide plate, flat trained, understood in a plane extending in two directions optical fiber element.

Expediently, each light emission region 30a, 30b, 30c, 30d has a plurality of light extraction prisms. In order to enable an accurate imaging via the corresponding micro-exit optics 220, prisms with an angle of incidence of approximately 40 °, which decouple the light in parallel, have proven to be practicable. The angle of attack can also be varied, so that a uniform light extraction takes place. The light extraction prisms are arranged to couple out the light from the light guide plate 31a, 31b, 31c, 31d in a direction substantially parallel to the optical axis. The light extraction prisms are preferably perpendicular to the propagation direction of the light in the light guide plate.

For the positioning of the optical fiber optics, two different embodiments have proven to be particularly useful.

According to a first embodiment, in which, as can be seen below, the at least one additional light source 3a, 3b preferably replaces the substrate plate for the entrance optics 21 and / or exit optics 22, the entrance optics 21 and the exit optics 22 are each referred to as micro entrance optics. Arranged array and micro-exit optics array, wherein the micro-entrance optics array has a plurality of Lichtabstrahlbereichen 30a, 30b associated, preferably planar trained intermediate regions 211 (this is particularly in the FIG. 1a visible).

The intermediate regions 211 of the micro-entrance optical array are characterized in that they have no micro-entry optics - in this case no convex lens. In this Meaning, the light penetrating into the projection device through these intermediate regions 211 is irrelevant to the formation of the intermediate image and thus irrelevant to the first light function.

The Lichtabstrahlbereiche 30a, 30b are in the Lichtabstrahebene preferably (see FIG. 1a ) distributed like a checkerboard. The intermediate regions 211 are likewise distributed in a checkerboard pattern in the micro-entrance optics array, the light emission regions 30a, 30b being arranged downstream of the intermediate regions 211 (viewed in the direction of the optical axis of the projection device 2). This means, for example, that a light emission region 30a, 30b is placed behind each intermediate region 211 of the micro entrance optics array (seen in the direction of the optical axis of the projection device 2) (see, for example, FIG FIGS. 9 to 11 ).

It may be expedient if the intermediate regions 211 are designed to be impermeable to light or a shielding element 23 is provided with the opaque shielding regions 230 corresponding to the intermediate regions 211 (see FIG FIG. 3 ). The shielding element 23 serves, for example, to shield the intermediate regions 211 from the light of the at least one light source 1.

As a result, it can be achieved, for example, that the light of the at least one light source 1 does not impinge on the light emission regions 30, is not scattered thereon. This leads to the reduction of unwanted scattered light.

The shielding element 23 is preferably arranged in a plane orthogonal to the optical axis of the optical projection device 2 and preferably extends over substantially the entire light entry surface of the entrance optics 21.

It is advantageous if the shielding element 23 is arranged on the light entry side with respect to the entrance optics 21, for example at a light entry surface of the entrance optics 21, in particular on the light entry surface of the entrance optics 21 is applied, and preferably the light generated by the at least one light source 1 on the micro light. However, entry optics 210 can not come up with the intermediate regions 211 of the micro entrance optics array.

The shielding member 23 may, as FIG. 3 it can be seen to be formed as a planar aperture with a plurality of the opaque shielding regions 230 complementary breakthroughs. However, it is also conceivable that the shielding element 23 is formed as a continuous layer, wherein this layer has regions of different light transmittance / transparency. It is also conceivable that the translucency / transparency of these areas in a controlled manner, such as in a liquid crystal display, is changeable.

In this embodiment, the at least one additional light source 3a can function as a carrier / carrier element for the entry optics 21 ( FIGS. 1 and 7 to 9 ).

Preferably, the entrance optics 21 is arranged on one of the at least one first light source 1 facing side of the at least one additional light source 3a, for example applied, in particular glued.

The at least one additional light source 3a can function as a carrier / carrier element for the exit optics 22 ( FIG. 10 ).

Preferably, the exit optics 22 on one of the at least one first light source 1 opposite side of the at least one additional light source 3a is arranged, for example applied, in particular glued.

It is also possible to provide exactly two additional light sources 3a, 3b, wherein a first of the two additional light sources 3a carries the entry optics 21 and a second of the two additional light sources 3b carries the exit optics 22. As a result, for example, the variety of realizable secondary light functions can be increased.

In this case, it is expedient for the light emission regions 30a of the first additional light source 3a and the light emission regions 30b of the second auxiliary light source 3b to be configured and positioned relative to one another in such a way that light rays 300a, 300b generated by the corresponding light emission regions 30a, 30b are in different directions spread out non-overlapping areas of the projection device 2.

FIGS. 7 to 11 In particular, it can be seen that the Lichtabstrahlbereiche 30a and 30b can emit collimated light parallel to the optical axis of the projection device. In this case, the light-emitting regions 30a and 30b are dimensioned and positioned such that light rays 300a emitted by first light-emitting regions 30a are parallel to, for example, above (FIG. Fig. 10 ) of light beams 300b radiated from second light emitting areas 30b. When the first light emission regions 30a are positioned below an optical axis of a corresponding micro exit optics 220, the rays 300a at this micro exit optics 220 are refracted and imaged in an area above the horizon (HH line). If the second light emission regions 30b are positioned below an optical axis of a corresponding micro exit optics 220, the rays 300b on this micro exit optics 220 are refracted and imaged into an area below the horizon. In this way, with a first additional light source 3a a light distribution emitted above the horizon can be generated - for example a Signlight light distribution and with a second additional light source 3b a light distribution lying below the horizon - for example a daytime running light or direction indicator light distribution can be realized ,

In addition, the projection device 2 can have at least one diaphragm device 7, 8 which lies between the inlet optics 21 and the outlet optics 22 and which has at least one diaphragm device 7, 8 the apertures 70 corresponding to the intermediate regions 211 (see FIG FIG. 4 ). This has the advantage, for example, that the light which comes from the light emission areas 30a, 30b can pass unhindered to the corresponding micro exit optics 220. In addition, the diaphragm device 7, 8 can be configured to form the intermediate image, for example to create a low-beam distribution with an asymmetrical cut-off line, and / or to correct optical aberrations. The diaphragm device 7, 8 may comprise a plurality of diaphragms.

It is expedient to adapt the shape of the at least one diaphragm device 7, 8 depending on the light distribution of the first and / or the second type to be generated. So shows, for example FIG. 4 a diaphragm device 7 for producing a light distribution of the first type designed as a low-beam light distribution. The diaphragm device 7 can, for example, on the light exit side of the light guide plate 31a, 31b are applied and has an array of openings 70, which takes into account the intermediate regions 211 in the micro-entrance optical array or the opaque areas of the shielding element 23.

In a second preferred embodiment (see Figures 2 . 5 . 6 and 12 to 15 ), a first diaphragm element 4, 5 is provided, which first diaphragm element 4, 5 is the Lichtabstrahlbereichen 30c, 30d upstream and is arranged to shield at least the Lichtabstrahlbereiche 30c, 30d of the light of the at least one first light source 1. Conveniently, respective opaque areas 40, 50 are provided in the first panel member 4, 5 for shielding the light emitting areas 30c, 30d. Preferably, the at least one additional light source 3c carries the first diaphragm element 4, 5 (FIG. FIG. 2 ). Furthermore, it may be expedient if the first diaphragm element 4, 5 arranged on one of the at least one first light source 1 side - ie the light entry side - the at least one additional light source 3c arranged, for example applied, in particular glued.

Examination of the Lichtabstrahlbereiche 30c, 30d with the light of the at least one light source 1, with which a light distribution of the main light function, such as a low-beam light distribution is generated, can lead to an unwanted influence on the low beam and high, possibly inadmissible stray light values. The light guide plate can simultaneously represent the holder for the microlens array (micro entrance optics array and / or micro exit optics array). This simplifies the system, because in this case, the light guide plate can take the place of the substrate plate for micro-entry optics or micro-exit optics, whereby insertion loss of the projection device is reduced but also required space is smaller.

It should be noted at this point that many of the already mentioned conventional projection modules with micro-optical arrays have a carrier or a carrier element for diaphragms between their inlet and outlet optics. In the subject preferred embodiment, the at least one additional light source 3c carries the function of such a carrier.

The Lichtabstrahlbereiche 30c, 30d in the Lichtabstrahebene the at least one additional light source 3c, 3d, for example, a shape horizontally, transversely to the optical axis of the optical projection device 2 / to the main emission direction Z extending, vertically (in the direction of V) from each other, preferably equidistantly spaced Have stripes. In this case, it is expedient for the diaphragm element 4, 5 to have light-impermeable regions 40, 50 corresponding to these strips (see FIG FIGS. 5 and 6 ).

The light emission regions 30c, 30d are preferably arranged directly (for example 0-5 mm) after, for example, on the first diaphragm element 4, 5.

The first diaphragm element 4, 5 is preferably arranged between the entrance optics 21 formed, for example, as the abovementioned micro entrance optics array, and the light emission areas 30c, 30d.

In addition, the first diaphragm element 5 can be set up to form the intermediate image for a low-beam light distribution from the light emitted by the at least one light source 1. Such a diaphragm element may for example have a plurality of corresponding openings.

Preferably, aperture element 4, 5 is applied on the light exit side with respect to the entrance optics 21 on the side of the light guide plate 31c, 31d facing the at least one light source 1.

Furthermore, exactly two additional light sources 3c, 3d can be provided, with a first additional light source 3c carrying at least the first diaphragm element 4, 5, and a second additional light source 3d carrying the exit optical system 22 (see FIG FIGS. 14 and 15 ) and the first diaphragm element 4, 5 is disposed in front of the light-emitting regions 30c of the first auxiliary light source 3c.

Preferably, the exit optics, in particular the micro exit optics array on one of the at least one first light source 1 side facing away from the second additional light source 3d arranged, for example applied, in particular glued.

Referring to the FIGS. 14 and 15 That is, it can be said that the light-emitting regions 30c of the first auxiliary light source 3c and the light-emitting regions 30d the second additional light source 3d are designed and positioned relative to one another such that light beams 300c, 300d generated by the corresponding light emission regions 30c, 30d propagate in different, non-overlapping regions of the projection device 2. For example, the light-emitting regions 30c of the first auxiliary light source 3c in a lower region of the respective micro-optical systems and the light-emitting regions 30d of the second auxiliary light source 3d in an upper region of the micro-optical systems. It may be expedient if all Lichtabstrahlbereiche 30c and 30d are outside of the first beam path 100.

In addition, regardless of the number of additional light sources 3c, 3d, a second diaphragm element 6 can be provided. The second diaphragm element 6 can, for example, limit and / or collimate light emitted by the first additional light source 3c (see, for example, FIGS FIG. 13 and 15 ). Furthermore, the second diaphragm element 6 can be arranged in front of the light emission regions 30d of the second additional light source 3d. It is advantageous if the second diaphragm element is set up to shield the second additional light source 3d.

It should be noted at this point that, similar to the aperture device 7, 8 mentioned in relation to the first preferred embodiment, the first diaphragm element 4, 5 and the second diaphragm element 6 may additionally be arranged to form the intermediate image, for example one To provide low-beam light distribution with an asymmetrical cut-off line, and / or to correct optical aberrations ( FIGS. 12 to 15 ). The first diaphragm element 4, 5 and the second 6 may be formed as a planar diaphragm with a plurality of apertures.

FIGS. 12 to 15 show sectional views of an enlarged portion of a projection device of a motor vehicle light module according to a second embodiment with different numbers of aperture elements 4, 5, 6 and additional light sources 30c, 30d. As seen below, in this preferred embodiment, the at least one accessory light source may replace the shutter substrate or micro exit optics array substrate plate - the micro exit optics array substrate plate.

The FIGS. 12 to 15 It can be seen that the Lichtabstrahlbereiche 30c and 30d collimated light 300c, 300d, preferably parallel to the optical axis of the Radiate projection device 2. In this case, the light-emitting regions 30c and 30d are dimensioned and positioned such that light rays 300c emitted by first light-emitting regions 30c are parallel to, for example, above (FIG. FIGS. 14 and 15 ), Light beams 300d radiated from second light emitting portions 30d extend. If the first Lichtabstrahlbereiche 30c (the Lichtabstrahlbereiche 30c of the first additional light source 3c) thereby positioned below an optical axis of a corresponding micro-exit optics 220 and a corresponding micro-optical system, the beams 300c are broken at this micro-exit optics 220 and into a Area shown above the horizon. In the automotive lighting technology, the horizon is often referred to as "line HH" or "HH line". This is a line corresponding to the horizon on a measuring screen on which light distributions generated by light modules are measured in a motor vehicle lighting technology laboratory. Line HH is part of the screen coordinate system that is common in automotive lighting technology. Line HH is a horizontal line that runs parallel to the road surface (in the laboratory - imaginary roadway) and through an intersection HV of the photometric beam axis from the center of the light module to the screen. The point HV is the origin of the screen coordination system.

If the second light emission regions 30d (the light emission regions 30c of the second additional light source 3c) are positioned below an optical axis of a corresponding micro exit optics 220 or a corresponding microoptical system, the rays 300d are refracted at this micro exit optics 220 and into one Area shown below the horizon. In this way, for example with a first additional light source 3c, a light distribution emitted above the horizon can be generated - for example a signal light distribution and with a second additional light source 3d a light distribution lying below the horizon - for example a daytime running light or direction indicator light distribution become. The light emission regions 30c, 30d are arranged, preferably directly, on or behind the corresponding opaque region of the corresponding (first or second) diaphragm element 4, 5, 6.

In addition, it can be provided that the first additional light source 3c also carries the second diaphragm element 6.

Preferably, the second diaphragm element 6 on one of the at least one first light source 1 opposite side of the first additional light source 3c, preferably the light guide plate 31c, 31d, arranged, for example applied, in particular glued.
