Description
Technical Field
The invention relates to a headlight for a motor vehicle, comprising a preferably high-resolution and adaptive high beam module and a housing, wherein the high beam module has a light module for generating light and at least one optical imaging system downstream of the light module in the main radiation direction, which images the light generated by the light module in a region in front of the high beam module.
The invention also relates to a motor vehicle having at least one, preferably two, headlights as described above.
Background
Motor vehicle headlights with high beam modules are completely known from the prior art. The high beam module is typically also used, as its name implies, to generate a high beam profile of a vehicle, for example a motor vehicle. In this case, the switched-on high beam module usually emits strong light which is sufficient for illuminating an area in front of the vehicle which extends spatially to a great extent (typically over several tens to several hundreds of meters) in the direction of light propagation. With the advance of technology, high-resolution high beam modules are used more and more frequently in motor vehicle headlights. Such high beam modules in particular allow the emitted high beam profile to be adapted to certain traffic conditions and are therefore often referred to as "adaptive high beam modules" or "high-resolution adaptive high beam modules". The determined traffic situation may comprise, for example, stationary and/or moving objects in the front zone of the motor vehicle driving forward, which objects are faded out by the adaptive high beam module (ausgeblendet). This achieves the function of a so-called "glare-free high beam". However, it is known that these high beam modules are not possible and allowed to be used in all traffic situations. For example, when driving within a city according to the prevailing traffic regulations, it is not permissible to keep the high beam module on or to radiate high beams. Only a light distribution that is diluted (abgebledet) is allowed to be used here. This results in that the high beam module must remain switched off substantially all the time in the case of urban driving.
Furthermore, there is a constantly increasing demand for headlights which realize additional lighting scenes in addition to the already known lighting scenes (e.g. low beam, (adaptive) high beam, turning beam, fog beam, etc.), such as ground projection or ground markings or parts of low beam. These additional lighting scenes should assist the driver and also assist other traffic participants (including pedestrians). A defined ground projection can prove particularly useful in severe weather conditions, such as rain or snow, or also in the case of a poor road surface, and can mark lane markings, turning arrows, guide lines, zebra stripes, etc., which are difficult to see or can no longer be seen at all, and can be made visible again to the driver and other traffic participants.
The concepts of "ground projection" and "ground mark" in connection with the present invention are understood to be those light distributions as follows: the light distribution occupies at least one small region (Spot) in the front region of the motor vehicle compared to, for example, the low-beam distribution and is arranged on the road at a distance of 5 meters up to 40 meters, preferably 5 meters up to 25 meters, from the motor vehicle.
However, the use of conventional high beam modules is limited to adaptive high beams, for example to glare-free high beams, since the field angle of the high beam module is only sufficient for conventional (or for adaptive high beams in the above sense). The opening angle itself is limited by the currently available light technology.
Disclosure of Invention
The object of the present invention is therefore to provide a headlight with a high beam module, which offers added value for the use of the high beam module and enables the above-mentioned additional lighting scenes.
This object is achieved according to the invention by a headlight of the type mentioned at the outset in that: the headlight comprises at least one carrier arranged in the housing so as to be pivotable, in particular rotatable, about at least one axis, wherein at least one deflection device is assigned to the carrier, which deflection device serves to deflect the carrier about the at least one axis with respect to the housing, wherein the light module and the optical imaging system are accommodated in the carrier, wherein the deflection device deflects the carrier about the at least one axis by an angle of between 0 ° and a maximum angle, preferably between 0 ° and 13.5 °, in particular between 0 ° and 10 °, and wherein the imaging system images the light generated by the light module as at least one partial light distribution in a region in front of the high beam module, preferably in a region between 5 and 40 meters in front of the high beam module, in particular in a region between 5 and 25 meters in front of the carrier with a maximum angle of deflection, wherein the at least one partial light distribution is configured as a partial low-beam light distribution and/or as a marker light distribution, in particular as a ground marker light distribution.
The support for accommodating the light module and the optical imaging system can be adjusted to any position within a defined range of motion (for example between 0 ° and 13.5 °, preferably between 0 ° and 10 °). In this way, a further, different projection plane can additionally be realized, which lies below the originally defined high beam range and cannot be realized with a standard high beam module, which is arranged essentially rigidly (apart from the basic adjustment) in the headlight. Within these provided projection planes, the high beam module can be used to show different images or illumination scenes.
In addition to this, it can be provided that: the light module is fixedly arranged in the housing, the optical imaging system is accommodated in a carrier, the carrier is arranged in the housing so as to be pivotable, in particular rotatable, about at least one axis, the deflection device deflects the carrier about the at least one axis by an angle of between 0 ° and a maximum angle, preferably between 0 ° and 13.5 °, and the imaging system images the light generated by the light module as at least one partial light distribution in a region in front of the high beam module, preferably in a region between 5 and 40 meters, in particular in a region between 5 and 25 meters, in front of the high beam module, with the carrier being pivoted by the maximum angle, wherein the at least one partial light distribution is designed as a partial low beam distribution and/or as a marker light distribution, in particular as a ground marker light distribution.
In this embodiment, only the optical imaging system is deflected and is therefore adjusted to an arbitrary position (deflected position) within a defined range of motion. In this case, it is advantageous if the light module can be arranged rigidly (although this does not exclude a basic adjustment of the light module) in the housing of the headlight and does not have to be pivoted together. The optical imaging system can be connected in a deflectable manner to a light module fixed in the housing, for example by means of a hinge element.
It may also be expedient for the deflection device to be fixedly connected to the housing and to comprise an electric and/or mechanical adjusting device which, in conjunction with the support, deflects the support. The connection of the deflection device to the housing may be advantageous in view of the alignment of the headlight.
With regard to the number of components in the headlight, provision can be made for: the carrier is constructed integrally with the optical imaging system.
With regard to the installation of the high beam module in the headlight, it may be expedient: the high beam module comprises a holder which accommodates the light module, wherein the holder is fixedly arranged, in particular fixed, in the housing.
In a further development of the invention, it can be advantageously provided that the deflection device is fixedly connected to the holder and comprises an electric and/or mechanical adjusting device which, in conjunction with the support frame, deflects the support frame. Mounting the deflection device at the holder may be advantageous, for example, when replacing the high beam module. In this case, the entire high-beam module can be removed from the housing after the fastening frame and the support frame have been released.
It may be appropriate to consider the generation of a light image: the light module comprises at least one, preferably two or more light sources, which illuminate the illumination object in the on-state, and at least one illumination object, which diverts and/or converts the light generated by the light sources, wherein the light sources and the illumination object are arranged with respect to the optical imaging system such that substantially all diverted and/or converted light enters the optical imaging system.
With regard to the quality of the light image, it may be advantageous if the illumination object or the intermediate image generated by the illumination object is arranged substantially in a focal plane, preferably a focal point, of the optical imaging system. In a projection module with a reflector, for example a pseudo-ellipse, the illumination object can first generate an intermediate image, which is preferably located in the focal plane of the imaging system, which images the intermediate image before the high beam module.
In a preferred embodiment of the invention, provision can be made for: at least one, preferably all, light sources are configured as LED light sources, and preferably at least one illumination object is configured as a micro mirror array, preferably as a micro scanner. The light modules together with the optical imaging system form a high-resolution LED-based projector with which light images of different shapes and colors can be generated (see fig. 6 to 9).
In addition to this, it can be provided that: at least one, preferably all, light sources are configured as laser light sources, and the at least one illumination object is configured as a light conversion element.
It may be desirable here to: the light module has light redirecting elements which redirect the light generated by the laser light source/laser light sources onto the light conversion means, wherein at least one of the light redirecting elements preferably comprises a plurality of micromirrors.
The use of lasers in headlamps has already been elucidated in the specialist literature and is part of the prior art. In most cases, the working distance of the laser beam is used. In the headlight according to the invention, the laser module offers the following advantages, for example: finer resolution of the light image can be achieved and the intense laser light is substantially well visible even in extremely inclement weather conditions.
It may be expedient if, in the installed state of the headlight in the motor vehicle, the at least one axis extends substantially horizontally and transversely to the main beam direction of the headlight. In the case of at least one axis thus oriented, the light module "tilts" substantially downward in the case of a deflection, which leads to a drop in the radiated light image and to a shortening of the spacing between the light image and the motor vehicle.
In order to reduce imaging errors when a carrier accommodating the optical imaging system is deflected, it may be advantageous if the at least one axis lies in a focal plane of the imaging system, preferably extending through a focal point of the optical imaging system.
Provision can advantageously be made for: the at least one partial light distribution is configured as one, two or more ground marker light distributions, wherein each ground marker light distribution is selected from one of the following light distributions:
a guide line radiation light distribution, which may be particularly advantageous in case the road edge is badly marked or soiled (snow, sand, mud, etc.);
a driving lane width indicator light distribution, which may be advantageous in case of difficult to see road markings in overtaking maneuvers;
braking maintenance light distribution, which may be useful for the purpose of maintaining a safe separation from a vehicle driving ahead or from other obstacles in front of the motor vehicle;
-a distance indicator light distribution;
a directional arrow light distribution, wherein the distance indicator light distribution and the directional arrow light distribution are preferably radiated simultaneously, and the distance indicator light distribution displays the distance to the intersection to the driver, and the directional arrow light distribution informs the other traffic participants of the intention of the driver. In addition to this, this directional arrow light distribution can be advantageous when the driver forgets to deactivate the driving direction indicator after the end of the turning action;
-a stop line light distribution;
-crosswalk light distribution;
pedestrian warning light distribution, which alerts pedestrians, through symbols projected onto the ground, to possible hazards caused for example by other vehicles. This can be advantageous when, for example, a pedestrian is descending from a tram and wants to arrive immediately on the opposite road side and here selects a route behind the tram for his action and does not pay sufficient attention to the oncoming traffic;
-parking spaces identifying light distribution. The parking space marking light distribution is not understood here as a parking aid known from the prior art, but rather as the following light distribution: this light distribution makes it possible for the driver and/or the motor vehicle passengers to notice the possibility of parking in a series of vehicles, for example, parked densely against one another, at the edge of a road or in a public or private parking garage or in a parking garage or underground parking garage.
The stop line light distribution, the crosswalk light distribution, and the pedestrian warning light distribution may be radiated collectively or individually, and assist the pedestrian and the driver in the case of a crosswalk sign that is difficult to see (see fig. 9).
The object mentioned at the outset is also solved according to the invention by a motor vehicle having at least one sensor unit for detecting objects outside the motor vehicle and at least one control unit, wherein the control unit is assigned to at least one high beam module, preferably two high beam modules, and the at least one sensor unit, wherein the control unit controls the at least one high beam module, preferably two high beam modules, as a function of the objects detected by the sensor unit and/or the motor vehicle speed and/or the state of the driving direction indicator, such that the at least one high beam module, preferably two high beam modules, radiate light for forming at least one partial light distribution, which is formed as a partial low beam distribution and/or as one, two or more ground marking light distributions, wherein each ground marker light distribution is selected from one of the following light distributions:
-a pilot radiation distribution;
-a driving lane width indicator light distribution;
-braking the maintenance light distribution;
-a distance indicator light distribution;
-a directional arrow light distribution;
-a stop line light distribution;
-crosswalk light distribution;
-a pedestrian warning light distribution;
-parking spaces identifying light distribution.
Provision can advantageously be made here for: the at least one headlight has a mounting height of substantially 75 to 90 cm and the support bracket can be pivoted in the range of 0 ° to 13.5 °, in particular between 0 ° and 10 °.

Detailed Description
Reference is first made to fig. 1. In this figure, a preferred embodiment of the headlight according to the invention and its associated components is schematically shown. The motor vehicle headlight has a high beam module 1 arranged in a housing 2. The high-beam module 1 comprises here a light module 3 for generating light 4, at least one optical imaging system 5 downstream of the light module 3 in the main radiation direction OA, which imaging system 5 images the light 4 generated by the light module into a region in front of the high-beam module 1 (in the main radiation direction OA). In the embodiment shown here, the imaging system 5 is fixedly connected to the light module 3, which is to say only: the imaging system 5, which can be configured as an optically relevant component, such as a lens, diaphragm, mirror, prism, etc., cannot be deflected or even be configured as a light module 3And cannot move. At least one support frame 6 is provided in the headlight for accommodating the light module 3 and the optical imaging system 5. In addition, the housing 2 typically has a receiving frame 20, which is arranged fixedly, for example, fixed in a form-fitting manner (formschluessig) in the housing, and which receives the carrier frame 6 in such a way that the carrier frame 6 is mounted in the receiving frame 20 so as to be pivotable, in particular rotatable, about at least one axis S relative to the housing 2. However, the presence of the housing rack 20 in the case 2 is not essential. Means should be provided only to be able to arrange the bearing bracket 6 in the housing 2 in a manner such that it can be deflected, in particular rotated. Such devices are common in motor vehicle construction and are completely known to the expert. The axis S is according to the invention arranged in a horizontal plane perpendicular to the main radiation direction, which coincides with the optical axis OA of the optical imaging system. The term "horizontal" relates here to the state in which the headlight is installed in the motor vehicle. In order to deflect the carrier 6, at least one deflection device 7 is provided in the headlight according to the invention, which deflection device 7 can be designed, for example, as a linear actuator (Linearsteller) or as a rotary drive (rotationtransmitter), which deflection device is preferably fixedly connected to the housing 2 and can have a mechanical and/or electrical actuating device 9, which actuating device 9 engages the carrier at least one point, preferably two, three or more points, in order to deflect the carrier 6 about the axis S. The adjusting device 9 is configured such that the deflection device 7 can deflect the support frame 6 about the axis S at 0 ° (0 position) and a maximum angle WmaxAn angle W between (maximum deflected position) preferably between 0 ° and 13.5 °, in particular between 0 ° and 10 °. Here and entirely generally within the scope of the invention, the angle W is understood to be the "inclined position" of the support frame 6. The support frame 6 is tilted downward by deflection and is brought into the tilted position. The angle W (tilt position) is, for example, an angle between the optical axis (main radiation direction) OA and a horizontal plane (see, for example, fig. 4). An alternative illustration of the angle W is shown in fig. 2. When the support frame 6 is tilted downward, the angle W is positive.
It should be noted at this point thatThe method comprises the following steps: the light module 3 can generally, i.e. in each embodiment of the invention, be operated in different ways depending on the deflection position of the support. In the 0 position shown in fig. 1, the light module 3, in the on state, for example, radiates light for generating a partial high beam profile, which can, for example, supplement the low beam profile to the high beam profile. Which is understood in connection with the present invention as the "high beam mode" of the high beam module. From a predeterminable (for example 2 °) pivot position W of the support frame 60The light modules 3 emit light for generating a partial low beam distribution and/or a marker light distribution, preferably a ground marker light distribution, for example (see fig. 5 to 10). In this case, in particular the floor marking light distribution has a plurality of regions of different shapes (straight lines, squares, arrows, quadrangles, letters, pictograms) which at least partially overlap or do not overlap one another (see fig. 5 to 10), wherein these regions are located at a distance of maximally 40 meters in front of the motor vehicle. This is understood in connection with the present invention as the "ground mark mode" of the high beam module. Further technical differences between the modes of operation of the light modules are discussed further below.
Fig. 2 shows the headlight in fig. 1, in which the carrier 6 accommodating the light module 3 and the optical imaging system 5 is pivoted by a maximum angle Wmax. In this case, the high beam module 1 is operated in a ground marking mode, which is selected from the aforementioned predefinable deflection positions W0Can be activated.
In the development of the invention shown in fig. 3, the light module 3 can be arranged fixedly in the housing 2. The optical imaging system 5 is accommodated in the carrier 6 or is formed integrally with the carrier 6. The carrier frame 6 accommodating the optical imaging system 5 can be designed separately from the light module 3 or can be connected to the light module 3 in a pivotable manner, for example by means of a hinge element (not shown). The carrier 6 is arranged in the housing 2 in such a way that it can be pivoted, in particular rotated, about at least one axis S with respect to the light module 3 and thus with respect to the housing 2.
It is advantageous here that the light module 3 can be arranged substantially rigidly in the housing 2 and does not have to be deflected together. Here, "substantially rigid" is to be understood as: the light module 3 can only move in the range that relates to its basic adjustment. As a rule of thumb, this basic adjustment range is only a few degrees (e.g. 0 ° to 2 °), whereby the light module 3 is not intended to produce the above-mentioned ground projection or ground mark in its basic adjustment range. In addition, a fastening frame 10 can be provided in the headlight, which fastening frame 10 is arranged fixedly in the housing 2, is preferably connected to the housing 2 in a form-fitting manner, for example screwed, and accommodates the light module 3, as can be gathered from fig. 3. Furthermore, it can also be seen from fig. 3 that the deflection device 7 arranged in the headlight can be connected, preferably fixedly, to the holder 10 and comprises an electric and/or mechanical adjusting device 9, which adjusting device 9 is combined with the support frame 6 for deflecting the support frame 6.
Of course, the following technical features are optional: the deflection device 7 is arranged on the holder 10 and is preferably fixedly, for example positively, connected thereto. The deflecting device can be connected, preferably fixedly, for example in a form-fitting manner, as shown in fig. 1 and/or 2, in the embodiment shown in fig. 3 (and 4) as well to the housing 2.
As is illustrated in fig. 3 and 4, an axis S (the pivot axis of the carrier 6 in fig. 1 to 4) which is arranged according to the invention in a horizontal plane perpendicular to the optical axis OA can extend through the focal point F of the optical imaging system 5. This has the following advantages: each object, for example a light source, arranged in the focal point F can be imaged by the imaging system 5 substantially without distortion (imaging errors) when the support 6 accommodating the optical imaging system 5 is deflected.
For the sake of completeness, it should be noted that: for the sake of simpler expression, reference is made elsewhere in the scope of the entire disclosure to "focus". In reality, the concept of "focus" is a mathematical idealization. In this case, the light beam passing through the non-ideal optical imaging system cannot be imaged into the focal point or onto the focal plane, but rather can be imaged into the focal plane which includes the focal point. The focal plane may be a focal plane, but in general it may not be planar due to imaging errors (e.g. distortions), but may also be "constructed" curved, i.e. the beam is usually focused into a curved plane containing the focal point.
Fig. 4 shows the headlight of fig. 3, in which the support frame 6 accommodating the optical imaging system 5 is pivoted by a maximum angle Wmax. In this case, the high beam module 1 is operated in a ground marking mode, which is selected from the above-mentioned predefinable deflection positions W0Can be activated.
According to the invention, the light module 3 of the headlight in fig. 1 or fig. 3 comprises at least one, preferably two or more light sources and at least one illumination object, wherein the at least one light source illuminates the illumination object in the on state, which object diverts and/or converts the light generated by the light source, wherein the light source and the illumination object are arranged with respect to the optical imaging system such that substantially all diverted and/or converted light enters the optical imaging system. The illumination object is arranged here substantially in the focal plane F (in the focal point) of the optical imaging system 5.
In a particularly advantageous embodiment of the invention, the light module 3 is designed as a high-resolution projection system (HDP = high definition projector). Each light source of the high-resolution projection system may be configured, for example, as a laser light source or, preferably, as a high-power (with very high intensity) LED light source. The illumination object can be designed as a micro scanner (in the case of an LED light source) or as a light conversion device (in the case of a laser light source) known from the prior art. The light-converting means are also referred to as "phosphors" in the specialist parlance. Here, in the embodiments in fig. 3 and 4, the micro-scanner or phosphor is arranged in the focal point F of the optical imaging system 5.
Fig. 5 to 9 schematically show partial light distributions which can be generated with the headlight according to the invention operated in the ground marking mode. At least one partial light distribution 8 is superimposed here by the low-beam light distribution a and/or by the city light distribution SL. Specifically, the method comprises the following steps: fig. 5 shows a directed ray radial light distribution 8 a; fig. 6 shows a driving lane width indicator light distribution 8 b; fig. 7 shows a braking maintenance light distribution 8c, which may be used to maintain a safe distance, for example, from a vehicle traveling ahead; fig. 8 shows a distance indicator light distribution 8d and a direction arrow light distribution 8e as a turning aid, which may be activated, for example, when a flash FA (of a turning indicator) is manipulated; fig. 9 shows a stop-line light distribution 8f, a crosswalk light distribution 8g and a pedestrian warning light distribution 8h, which support not only the driver of a motor vehicle equipped with at least one headlight according to the invention but also other traffic participants. Here, in some of the above described cases (e.g. fig. 8 and 9) it may be appropriate to: dynamically radiating a ground marker light distribution. It is also merely true that the pivot position of the support bracket 6 in the headlight is not kept constant in the ground marking mode, but becomes greater and greater, for example, as the speed of the vehicle becomes smaller and smaller, so that the illuminated region on the road remains substantially stationary with respect to the road and approaches the vehicle.
For this purpose, at least one sensor unit for detecting objects outside the motor vehicle and at least one control unit can be provided in the motor vehicle according to the invention, wherein the control unit is assigned to at least one high-beam module, preferably two high-beam modules, and the at least one sensor unit, wherein the control unit controls at least one high-beam module, preferably two high-beam modules, as a function of the object detected by the sensor unit and/or the motor vehicle speed and/or the state (on/off) of a driving direction indicator FA (turn indicator), and adapts the deflection position of a support/supports, for example as a function of the motor vehicle speed and/or the state of the driving direction indicator (turn indicator).
Fig. 10 shows a front section of a motor vehicle described above, which has at least one headlight according to the invention. The distance P from the area illuminated on the road with the ground mark depends on the mounting height h of the at least one headlight and on the pivot position (angle) W of the support (not shown here) of the high beam module (not shown here). In the high beam mode, the headlight emits a partial high beam distribution FL, the mount in the headlight being in the 0 position, the optical axis OA being oriented substantially horizontally. In the ground mark mode (the radiometric word "STOP") of the high beam module, the spacing P can be reduced by increasing the angle W, so that the projected ground mark always remains on the same part of the road. The carrier (not shown here) is here "tilted" by an angle W between the horizontal and the optical axis OA'.
