    Motor vehicle headlight for emitting a long-range
    light distribution
    The invention relates to a light module for a motor vehicle headlight for emitting light for forming a light distribution in a region in front of the light module, wherein the light module comprises two or more primary light sources that generate light to form a main light distribution, and at least one secondary light source , which generates light for forming an additional light distribution, wherein the additional light distribution superimposed on the main light distribution for forming an overall light distribution, wherein the primary light sources associated with at least one primary reflector and is adapted to the light emitted from the primary light sources bundled and directed in an area in front of the light module in the form of the main light distribution, wherein the at least one secondary light source associated with an optical imaging system and is adapted to the radiated from the at least one secondary light source light in a region in front of the light module in the form of the Z depict the light distribution.
    Furthermore, the invention relates to a lighting device for a motor vehicle headlight with such a light module.
    In addition, the invention relates to a motor vehicle headlight with at least one light module of the type mentioned and / or with at least one above-mentioned lighting device.
    On top of that, the invention relates to a motor vehicle with at least one such motor vehicle headlight.
    In modern motor vehicle design more and more design freedom and compactness of the motor vehicle headlights are high. However, this often runs counter to the desire for more functionality and efficiency, which is why e.g. Laser light sources and LED light sources in light modules for the formation of light distributions in particular high beam distributions are increasingly used combined.
    The term "functionality" is to be understood as meaning that a two-stage high-beam light distribution can be realized, with the first stage achieving the legal distance minimum of a high-beam light distribution and the second stage achieving the legal maximum distance or the maximum range / performance / safety should.
    Furthermore, a combined use of laser light sources and LED light sources places particularly high demands on the adjustment of the individual units to one another, such as, for example, Alignment of the parallelism of the optical axes in a simple and compact form by means of a defined (minimum) number of setting elements / screws.
    A usable in a motor vehicle headlight laser light unit consists of at least one laser light source (laser diode) and at least one light conversion element (phosphorus short), since no direct laser light may be emitted to the road. Such laser light units offer themselves primarily because of their size and their Abstrahlungscharakteristikums. The light for generating a light image is generated in laser light units by irradiation of the phosphor with the laser light. In this case, the light source (that is, the area illuminated by a laser beam of the phosphor), with a phosphorus (with respect to the main emission of the laser light unit) upstream optical imaging system as a light image in front of the laser unit (and in a built-in motor vehicle headlamps state of the laser unit in front of the Motor vehicle headlight), relatively small (usually 100-900 microns, preferably less than 600 microns) may be formed. Consequently, the laser light unit can also be designed to save space. In this case, a laser light unit generates a bright and far-reaching photo. In contrast, LED light sources offer themselves for generating a broad light distribution or at least parts of a broad light distribution. (The advantages of such a combination are described inter alia already in WO2012161170A1, EP2551154A2 or in DE102013200925A1)

    First, reference is made to FIG. 1. In this an exemplary schematic arrangement of relevant for the light module according to the invention components is shown. The light module in this case has two primary light sources PLQ1, PLQ2, each with a primary light source associated primary reflector PR1, PR2, and a secondary light source SLQ1 with its associated from a secondary reflector SRI and a lens KL1 existing optical imaging system AS , The primary light sources PLQ1, PLQ2 designed here as light-emitting diodes (LED for light-emitting diode, for short) are designed to generate light for forming a main light distribution HLV (FIG. 2). The main light distribution HLV usually has a relatively short range. In many traffic situations, however, it is necessary to increase the range of the radiated main light distribution. To achieve this object, the secondary light source SLQ1 is provided according to the invention, which is formed in Fig. 1 as a light conversion means (in the art often called phosphor) of a laser light unit (not shown). Use of laser light units in automotive headlamps is well known in the art (see, e.g., Figures 3 and 7 in EP 2551154 A2). According to the invention, the laser light unit has such a laser light source (not shown) and such a light conversion means SLQ1 that, when the light conversion means is illuminated, sufficient luminous flux is emitted into a predetermined solid angle, preferably in relation to 4n (total space angle). As a result, the secondary light source SLQ1 generates (by conversion of the laser light at the light conversion means SLQ1) light for forming a long-range additional light distribution ZLV (FIG. 2b). The primary reflectors PR1, PR2 associated with the primary light sources PLQ1, PLQ2 combine the light emitted by the primary light sources PLQ1, PLQ2 and deflect it into an area in front of the light module. Here, the term "in front of the light module" refers to an area that lies in the light propagation direction of the light bundled by the primary reflectors PLQ1, PLQ2, Moreover, it should be noted at this point that the "collimated light" is convergent or divergent or parallel Light beam can be formed. The primary reflectors PR1, PR2 are preferably designed as paraboloid reflectors and bundle (in vertical, with reference to a light module, which is installed in a motor vehicle headlight, direction V) that of preferably in a focal point PB1, PB2 of the respective primary reflector PR1, PR2 arranged primary light sources PLQ1, PLQ2 generated light to a substantially parallel light beam. In addition, the
    Primary reflectors PR1, PR2 be integrally formed with each other or separated. The imaging system associated with the secondary light source SLQ1, as briefly explained above, has the secondary reflector SRI and the lens KL1. In this case, the secondary reflector SRI is preferably designed as a hyperboloid reflector and the lens KL1 as a collimator lens. The hyperboloid reflector SRI has two focal points BPI, BP2, where the first focus BPI is a real focal point in which the secondary light source SLQ1 (here the light conversion means) is located, and the second focus BP2 is a virtual focus in which the extensions LS '(see Fig. 4) of the light beam LS originating from the real focal point BPI and reflected by the reflecting surface of the hyperboloid reflector (see Fig. 4) substantially coincide. In this case, the collimator lens KL1 is arranged such that one of its focal points KLB coincides with the virtual focal point BP2. As a result, the light reflected by the hyperboloid reflector SRI is focused into a substantially parallel (in the vertical direction V) light beam. However, the bundling into a substantially parallel light bundle is not necessary. It is quite conceivable to use a collecting or diverging lens instead of a collimator lens. Which lens is used here, for example, on the nature of the light module upstream attachment optics or any other existing optical imaging system (ie, for example, an array of apertures, lenses, mirrors, etc.) and the requirements for the shape of the main and / or the additional light distribution and / or the light distribution generated by the light module.
    It is also preferred that all the real focal lengths (ie the distance between the main plane and the focal point, the hyperboloid reflector the real focus, in which focal point the secondary light source is arranged) PBW1, PBW2, HBW1 of all the reflectors used in the present invention are substantially the same are. Thus, the installation space depth of the light module can be minimized, thereby taking into account the design freedom and compactness more and more frequently imposed in today's headlamps.
    In addition, the primary reflectors and the secondary reflector are arranged such that their optical axes POl, P02, SOI are parallel to each other. This is particularly relevant for the quality of the emitted light image.
    The arrangement of the essential components of the invention shown in FIG. 1 is particularly advantageous for a light module if the light module is set up to produce a total light distribution designed as a long-range high beam light distribution LFL (FIG. 2 a). In this case, the primary light sources PLQ1, PLQ2 produce, in cooperation with the primary reflectors, a short-range high-beam light distribution HLV (FIG. 2) which overlays short-range high-beam distribution HLV from a long-range auxiliary high-beam light distribution ZLV (FIG long-range high-beam light distribution LFL (Fig. 2a) is thus formed total light distribution. In this case, the range of the long-range high-beam light distribution LFL measured by the distance between the light module and the llx line 11x is substantially twice as large as the range of the short-range high beam light distribution ZLV.
    The additional high-beam light distribution ZLV is arranged substantially in the middle of the short-range high-beam light distribution HLV (FIG. 2a). This advantageous effect is achieved by the arrangement, shown schematically in FIG. 1, of the primary light sources PLQ1, PLQ2 and the primary reflectors PR1, PR2 with respect to the secondary light source SLQ1 and the imaging system AS, in which arrangement the primary light sources PLQ1, PLQ2 This means, finally, that in a projection of the positions of the primary and secondary light sources (the light conversion means) on a perpendicular to the optical axes POl, P02, SOI of the corresponding reflectors PR1, PR2, SRI arranged plane, the projections of the primary light sources PI, P2 switch the projection of the secondary light source S1.
    3 shows a ready-to-install light module according to the invention in a perspective view. The coordinates shown indicate the light exit direction /
    Main radiation direction Z, the horizontal direction H, which is normal to Z and normal to the vertical direction V. In this case, the terms "horizontal" and "vertical" refer to the state of the light module installed in a motor vehicle headlight, which motor vehicle headlight is installed in a vehicle. The primary light sources PLQ1, PLQ 2 and the primary reflectors PR1, PR2 are combined into a first overall unit (LED unit) and the secondary light source and the optical imaging system AS are combined to form a second overall unit, preferably a laser light unit. In view of the above, as mentioned above, the laser light unit comprises a whole of a laser light source which generates light for irradiating the light conversion means, which light conversion means functions as the secondary light source, and an imaging optical system AS which generates the one by converting the laser light to the light conversion means Light is projected in front of the light module. In addition, the primary reflector PR1 of the LED unit is integrally formed with the primary reflector PR2. This has the advantage that only one adjustment (see also FIG. 6) is sufficient for the entire LED unit. In addition, such an integral formation of the primary reflectors PR1, PR2 is preferred from an aesthetic point of view, since thus an enclosure of the laser light unit is made possible by the LED unit. Such an enclosure has, for example, the following advantage: This allows essentially parallel alignment of the optical axes PO1, PO2, SOI, and as a result reduces angular errors.
    In the context of the present invention, the term "angle error" is understood to mean an optical aberration which is arranged in modules separate from at least one light source and at least one associated with at least one light source in a motor vehicle headlight, which modules for forming a common light image The light distributions generated by the respective light modules are measured on a measuring screen placed at a distance (typically of 25 meters) transverse to the main direction of propagation of the light and the optical axes of the respective modules are adjusted in such a way that the light image on the measuring screen Essentially the requirements, preferably legally prescribed standards (for example, the ECE regulations) corresponds, which can be characterized by a substantially inexact parallel alignment of the optical axes of the modules after the screen and before the screen distortion of the desired light image arise.
    From a side view of the light module according to the invention shown in FIG. 4, a preferred arrangement of the focal points PB1, PB2, BPI, BP2, KLB of the optically relevant components of the light module can be seen. In this case, the hyperboloidal shape of the secondary reflector SRI is particularly advantageous since the focal lengths of the hyperboloid reflector are therefore kept small so that the secondary light source can be arranged very close to the reflector. As a result, the installation space depth of the light module, e.g. in comparison with a light module in which the secondary reflector is designed as a reflector of another type, for example as a paraboloid reflector.
    Having illustrated the preferred exemplary embodiments of the light module, reference will now be made to the arrangement of the light module in a lighting device. Fig. 5 shows schematically an exemplary arrangement of the essential components of the lighting device according to the invention. In this case, the light module is shown as two separate units formed total units. The first overall unit (LED unit) comprises the above-described but not shown here primary light sources PLQ1, PLQ 2 and also described above but not shown primary reflectors PR1, PR2, the second total unit (laser light unit) includes the above-described but not shown secondary light source SLQ1 and also described above but not shown here optical imaging system AS. In addition, the lighting device comprises a main support HT, which is adapted to receive the LED unit, an additional support ZT, which is adapted to receive the laser light unit, and a support frame TR, which for receiving both the main support HT as Also of the additional carrier ZT is set up. The support frame TR is pivotable about at least one axis TA (whereby various light functions, such as cornering light function, can be realized in the motor vehicle headlight), wherein during pivoting of the support frame TR received by the support frame TR main and auxiliary support with the support frame TR are pivoted , When receiving the support in the support frame is provided that the main support HT and the additional support ZT are connectable to the support frame TR, wherein the position of the support with respect to the support frame (for example along the in Fig. 5 with arrows Directions) is changeable / adjustable. Thereby, e.g. the alignment of the optical axis LOA of the LED unit to the optical axis SOI of the laser light unit are adjusted. For connecting the carrier to the support frame and for adjusting the support with respect to the support frame, a Einstelldreieck system is provided, wherein in the preferred embodiment shown in FIG. 5, a first Einstelldreiecksystem EDS1 for adjusting the LED unit receiving the main support HT and a second Einstelldreieck system EDS2 for adjusting the laser light unit receiving auxiliary carrier ZT is set up. The position of the first triangulation system EDS1 is rotated with respect to the position of the second triangulation system EDS2 by 90 ° about the optical axis of the laser light unit SOI (equal to the optical axis of the secondary reflector SRI). This simplifies the setting variability. However, it is quite conceivable that the Einstelldreieck-systems EDS1, EDS2 not at all or at a different angle, for example, by 180 °, are arranged rotated to each other.
    In the context of the present invention, the term "adjustment triangle system" is generally understood to mean an adjustment system which adjusts the carrier with respect to the carrier frame via three adjusting elements (eg adjusting screws) which are rotatably connected to the corresponding carrier and to the carrier frame Adjustment is normally carried out by means of mechanical and / or electromotive actuating means associated with the illumination device Such adjustment systems are known in the prior art (see, for example, Applicant's application A 50329/2013).
    In a preferred embodiment of the invention, the laser light unit, as shown in FIG. 5, an elongated laser light unit housing HM, which arranged laser light unit housing in a receiving opening of the laser light unit housing AO of the support frame TR and through this Receiving opening AO is feasible. Thereby, the laser light unit in a not connected to the support frame TR state of the laser light unit receiving additional support ZT can be pulled out of the receiving opening AO and removed the lighting device. This substantially facilitates the replacement of the laser light unit and / or its components when technical faults occur. In a state in which both carriers (the main carrier HT and the additional carrier ZT) are connected to the support frame TR by means of the adjusting elements of the corresponding Einstelldreieck systems EDS1, EDS2, the connection of the additional support ZT is carried out on the support frame TR behind the support frame and the connection of the main support HT to the support frame TR in front of the support frame. The term "behind" or "before" here means that the additional support with respect to the support frame TR against the direction of travel / light exit direction or the main support HT with respect to the support frame TR in the
    Direction of travel / light exit direction are arranged. In this case, a cascaded setting of the lighting device can be realized. In the context of the present invention, the term "cascaded adjustment" refers to a setting in which the main emission direction of the illumination device can first be adjusted by means of the first delta triangulation system EDS1 and subsequently the emission illumination of the laser light unit with respect to the main emission direction by means of the second delta triangulation system EDS2 can be adjusted.
    In addition, with arrows in Fig. 5 exemplary directions are shown along which the main and / or the additional carrier can be adjusted with respect to the support frame / can.
    FIG. 6 shows a perspective view of the illumination device of FIG. 5, in which the main carrier and the additional carrier are formed as a heat sink. In addition, in Fig. 6 as adjusting screws ZES1, ZES2, ZES3, HES1, HES2, HES3 asugebildete adjusting elements of the Einstelldreiecke EDS1, EDS2 shown which for engaging the mechanical and / or electromotive actuating means of the Einstelldreieck-systems EDS1, EDS2 and for connecting the main and auxiliary carrier are arranged with the support frame. Each adjusting screw has a threaded section GA and a ball head KK. The passage openings of the support frame and the additional support each have a counter-threaded portion, which are adapted to cooperate with the threaded portions of the corresponding adjusting screws and on the one hand to connect the main and / or the additional support to the support frame and on the other hand, the position of the main and / or the additional carrier with respect to the support frame, as shown in FIG. 6 can be seen.
    In a connected state of the support frame with the main support, the threaded portions of the (three) adjusting screws HES1, HES2, HES3 are arranged in the designated (three) through holes of the support frame TR such that the threaded portions of the adjustment screws into the corresponding mating thread portions of the support frame attack. In this case, the ball head engages in each case an adjusting screw in the corresponding receptacle adapted to receive a ball head of the main carrier, as shown in Fig. 6.
    Furthermore, in a connected state of the support frame TR with the additional support ZT, the threaded portions of the (three) adjusting screws ZES1, ZES2, ZES3 are arranged in the provided (three) passage openings of the additional support ZT such that the threaded portions of the adjusting screws engage in the corresponding counter-threaded portions of the additional carrier ZT, wherein the ball head each engages an adjusting screw in the corresponding adapted for receiving a ball head receiving socket of the support frame, as shown in Fig. 6.
