    Lighting device for vehicle headlights
    The invention relates to a lighting device for a vehicle headlight, which comprises a first light module, a second light module and a third light module, wherein the first light module generates a first predetermined total light distribution in a vehicle-mounted state in an area in front of the motor vehicle, and the second light module generated in a vehicle-mounted state in a region in front of the motor vehicle, a first predetermined partial light distribution, and the third light module in a vehicle-mounted state in an area in front of the motor vehicle generates a second predetermined partial light distribution, and wherein simultaneously lit first and second Light module, the first partial light distribution at least partially overlaps the first partial light distribution, so that a second total light distribution is formed.
    Furthermore, the invention relates to a vehicle headlight with at least one such lighting device.
    Moreover, the invention relates to a motor vehicle with at least one such, preferably with two such vehicle headlights.
    According to the legal regulations, light distributions of vehicle headlights have to fulfill a number of conditions. In addition to legal requirements, customer requirements often also have to be met, for example. be implemented with respect to homogeneity of a light distribution.
    For example, for legal reasons, transitions from brightly lit to dimmed light distribution ranges are defined as fuzzy cut-offs (HD boundaries), and the HD boundaries must not be imaged to be too sharp or too blurry, i. the maximum sharpness (the degree of hardness of the HD limit is determined by a measure G) of the HD limit is prescribed by law (in ECE member states and lower limits for this measure are required by law). Such a blurring of the HD limit results in the driver perceiving the HD limit as being "softer" and subjectively more pleasant.
    The quantification of the sharpness or blurring of this HD boundary is effected by the maximum of a gradient along a vertical section through the HD boundary. For this purpose, the logarithm of the illuminance is calculated at measuring points in 0.1 ° intervals and their difference is formed, whereby the gradient function is obtained. The maximum of this
    Function is called the gradient of the HD boundary. Since this definition imitates the perception of human brightness only in an inaccurate manner, differently perceived HD limits can have the same measured gradient value or different gradients can be measured for similar-looking HD boundaries.
    Another topic is the generation of segmented light distributions. These are used, for example, in the generation of dynamic light distributions, such as a dazzle-free high beam. In technical terminology, one often speaks of so-called ADB (Adaptive Driving Beam) systems. In specific embodiments, such a dynamic light distribution is built up from one or more individual light distributions. For this purpose, for example, with individual light sources, which is assigned in each case an optical attachment, respectively, a small segment generated in the light image, the superposition of these light segments then gives the entire light distribution. By switching off individual light sources, individual segments in the light image can be switched off, ie not illuminated. The segments are usually arranged in rows and / or columns.
    The use of different light modules to produce a legally prescribed total light distribution can lead to sharp, perceived as unpleasant transitions between the light distributions generated by the individual light modules. These transitions or so-called inhomogeneities can be identified in advance of the vehicle. Consequently, when using a light distribution that has very large gradients in the intensity transition, it perceives the human eye very clearly.
    One approach known in the art to soften the gradient is to adjust the curvature of the optical attachment (see, e.g., DE 102009053581 B3) as far as the optical system (lens diameter, lens intercept) permits. This approach finds particular application in the devices provided with an attachment optics. Such an adaptation may e.g. achieved by the use of microstructures on the interfaces of imaging lenses and is known from the prior art.
    With a change in curvature at the exit surface of a lens attachment, the example strip-shaped light distributions are varied in size and thereby distributes a certain proportion of luminous flux over a larger Elächen. Thus, the HD area is widened and the human eye perceives the illumination transition to be less constricting. However, this approach has only limited applicability. For example, can not manipulate the large gradient at the bottom of a segmented high beam distribution, which will be referred to later, in this way. In another approach known in the art, transitions are made to homogenizing roughenings (e.g., by grit blasting) on the facing optical elements. The process of sandblasting always leads to different geometries in the tool or on the lens surface. This has the disadvantage that each production batch looks different and leads to (usually) small fluctuations of the gradient values.
    The abovementioned solutions can therefore not be used in general but only in special cases (see, for example, DE 102006052749 A1, DE 102008036193 A1, EP 2518397 A2, DE 102007052745 A1, DE 102007052742 A1).
    The described disadvantages of the prior art should be eliminated. It is therefore an object of this invention to provide a lighting device with which a light image can be realized that meets the legal requirements and at the same time is not perceived as disturbing.
    In order for lawful light intensity values to be achieved, first the intensity of the light emitted by the lighting device has to be measured. The measurement is usually done by a measuring screen is arranged perpendicular to the optical axis of the lighting device and illuminated at a certain distance in front of the lighting device. A special orthogonal pair of coordinates - hh-line and vv-line - is defined on the screen. The position of a point on the screen is given in degrees. The light intensity values are recorded in the form of a two-dimensional distribution and displayed, for example, as an isolux line diagram (isolux lines). The luminous intensity curve represents a section through the isolux distribution along a specific curve, wherein the sectional curve is usually a straight line that runs parallel to the ordinate (vv line) on the isolux line diagram. Such luminous intensity curves are used when comparing different light distributions.
    The above-described object is achieved with an illumination device mentioned above according to the invention that the second partial light distribution is completely below the legally prescribed hh line or adjacent to the hh line from below and at least partially overlaps the second total light distribution, with simultaneous activation of all three Light modules a third total light distribution is formed.
    In one of the preferred embodiments, the illumination device is designed in such a way that the first predetermined partial distribution has a lower limit which lies at least partially in the first predetermined total light distribution, which lower limit is at least partially overlapped by second partial light distribution with second and third light modules simultaneously lit.
    It has proven to be useful to describe the light distributions by the relevant luminous intensity curves. Thus, according to the invention, the second total light distribution is characterized by a first luminous intensity curve recorded along a defined cutting curve.
    It is expedient that the third total light distribution is characterized by a second luminous intensity curve recorded along the defined cutting curve.
    According to the invention, the overlap of the first total light distribution with the first partial light distribution is thus compared with the overlap of the first total light distribution, the first partial light distribution and the second partial light distribution. This comparison is made using characteristic luminous intensity curves and is quantified by radii of curvature of both curves (the use of the radii of curvature as a measure of quantification will be discussed later), where according to the invention the first luminous intensity curve and the second luminous intensity curve are each continuously differentiable at least twice.
    It should be noted at this point that the luminous intensity curves are formed by an interpolation, for example a spline interpolation. In this interpolation, certain specifications may be imposed on the smoothness of the balance curves (e.g., order of spline interpolation), in short, smoothness properties that the light intensity curves must meet.
    Preferably, the light intensity curves are recorded along a straight-line cutting curve.
    It is also particularly advantageous that the straight-line section curve runs parallel to the ordinate of the isolux line diagram.
    In order to compare the luminous intensity curves, a corresponding measure is required. It should again be noted that the object of the present invention is to reduce the intensity of the inhomogeneities of the light distributions. The intensity of inhomogeneity is reflected in how much the luminosity values change within a certain range. In terms of luminosity curves, this means how fast the curve rises or falls within a certain interval.
    As a measure of this intensity change rate, it is advantageous to choose the extent of the change in the radius of curvature along a slope region. Thus, a slope area where the minimum radius of curvature is large appears "flatter" than a slope area where the minimum radius of curvature is small, and Ergo becomes the light distribution in this area in the first case felt as a pleasant.
    It is thus advantageous that the minimum radius of curvature in at least one rise region of the first luminous intensity curve, in which the luminous intensity values are monotonically increasing, preferably in all rising regions, is less than or equal to the minimum radius of curvature in a rising region of the second luminous intensity curve, in which the light intensity Values are monotonously increasing, preferably in all rising ranges.
    In addition, it may be provided that the minimum radius of curvature in at least one gradient region of the first luminous intensity curve, in which the luminous intensity values are monotonically decreasing, preferably in all gradient regions, less than or equal to the minimum radius of curvature in a gradient region the second luminous intensity curve in which the luminous intensity values are monotonically decreasing, preferably in all gradients ranges.
    With regard to the shape of the second partial distribution, it is advantageous that the third light module is designed and / or arranged such that it illuminates a horizontally extended strip-shaped segment, the ratio of segment width to segment height being at least 2 to 1, preferably up to 10 to 1, is.
    Furthermore, it is conceivable that the third light module is designed and / or arranged such that it illuminates a horizontally extended strip-shaped segment, which segment lies in a range between approximately -20 ° and approximately + 20 ° horizontally.
    Moreover, it is advantageously provided that the third light module is designed and / or arranged such that, in a vehicle-mounted state, the vehicle being designed for right-hand traffic, it illuminates a horizontally extended strip-shaped segment, which segment is in an area between about -20 ° and about + 10 ° horizontally.
    In addition, provision may be made for the third light module to be designed and / or arranged such that it illuminates a horizontally extending strip-shaped segment in a vehicle-mounted state, the vehicle being designed for left-hand traffic, which segment is in an area between about -10 ° and about + 20 ° horizontally.
    It is conceivable that the third light module is designed and / or arranged such that it illuminates a horizontally extending strip-shaped segment on a measuring screen arranged vertically at a certain distance in front of the illumination device, the horizontal extent of which lies in a range between 20 ° and 40 ° , but preferably 30 °.
    In summary, the third light module illuminates a horizontally extending stripe-shaped segment in a horizontal angle range, which is generally between -20 ° and about + 20 ° and has a horizontal extent between 20 ° and 40 °, but preferably 30 °, but the Road traffic system can be adjusted so that the horizontal-angle range in the right-hand drive vehicles between about -20 ° and about + 10 ° and in the left-hand drive vehicles between about -10 ° and about + 20 °.
    Furthermore, it is advantageous that the third light module is designed and / or arranged such that it illuminates a horizontally extended strip-shaped segment, which segment lies in a range between approximately -4.5 ° and approximately 0 ° vertically.
    Likewise, it can be provided that the third light module is designed and / or arranged such that it illuminates a horizontally extended strip-shaped segment whose vertical extent in a range between 0 ° and 4.5 °, preferably between 3 ° and 4.5 °, lies.
    Thus, the third light module illuminates a horizontally extending stripe-shaped segment lying in a vertical angle range of about 0 ° to about -4.5 ° and its vertical extent in a range between 0 ° and 4.5 °, preferably between 3 ° and 4.5 °, lies. It is imposed on the segment the requirement that it is either completely below the hh line or adjacent to this line from below. For a specific illumination of the abovementioned areas, different designs and embodiments of the third light module are suitable.
    It has proven to be expedient that the third light module comprises at least one light source and at least one of the at least one light source associated optical attachment and / or at least one associated reflector.
    It is in principle possible that, in a specific embodiment, the reflector associated with the third light module is designed as a free-form reflector, for example as a free-form reflector with a paraboloid basic shape.
    Furthermore, it is advantageous that the light source arranged in the third light module is designed as a lamp, for example an incandescent lamp corresponding to the standard ECE-R37 or a gas discharge lamp corresponding to the standard ECE-R99. In one of the preferred embodiments, it is provided that the light source arranged in the third light module is formed from one, two or more LEDs. In one of the preferred embodiments it can be provided that the light source arranged in the third light module is designed as a laser light source.
    Furthermore, it is advantageously provided that the light source arranged in the third light module emits light in a predetermined or specifiable spectral range.
    It is expedient that the light source arranged in the third light module emits light whose color can be tuned to the color of the light emitted by the first light module and / or by the second light module.
    In a specific embodiment of the invention, it is provided that the first light module, the second light module and the third light module are arranged in a vehicle headlight housing.
    In another specific embodiment of the invention, it is provided that the first light module and the second light module are arranged in a vehicle headlight housing and the third light module is formed as an additional light module and arranged outside the vehicle headlight housing.
    Moreover, it is conceivable that the first total light distribution is a low-beam light distribution.
    Furthermore, it is advantageously provided that the first partial light distribution is a partial high beam distribution.
    In addition, it can be provided that the first partial light distribution is a partial high beam distribution, which is formed from one or more, preferably rectangular, segments and has a preferably rectilinear lower limit.

    10 shows a comparison of two luminous intensity curves recorded with hot H = 0 ° with a luminous third light module according to the invention and without a luminous third light module according to the invention, FIG.
    11a shows a gradient course with a luminous third light module according to the invention,
    FIG. 11b shows a gradient course without a luminous third light module according to the invention, FIG.
    FIG. 12 shows a vehicle headlight with light modules arranged within a housing, and FIG
    13 shows a vehicle headlight with a third light module according to the invention arranged outside a housing.
    Reference is first made to Figs. 1-3, which show three schematic schematic light distributions.
    1 schematically shows a first typical total light distribution, here in the form of a low-beam light distribution A, which is produced, for example, with a known light module 105 according to the prior art shown in FIGS. 12 and 13. The low-beam light distribution has a light-dark boundary 10, which in the case shown has a typical asymmetry for the application of the low-beam module in right-hand traffic countries.
    Fig. 2 shows schematically a segmented partial light distribution - the partial high-beam distribution F, which is formed from rectangular segments 30 extended in the vertical direction and has a lower limit 25, at which the light intensity of this partial high-beam distribution has a strong gradient. Such a partial light distribution can be produced, for example, with a known light module 106 according to the prior art shown in FIGS. 12 and 13.
    FIG. 3 shows schematically a partial light distribution Z, which lies completely below the hh line and superimposes the low-beam light distribution A. The partial light distribution Z partially overlaps the lower edge 25 of the partial high-beam distribution F, as shown in FIG.
    4 schematically shows a second typical total light distribution AF, which is a high-beam distribution which is produced by simultaneous illumination of the light modules 105, 106 shown in FIGS. 12 and 13 and which is superimposed on the low-beam light distribution A with the partial beam. High beam distribution F yields. Furthermore, FIG. 4 shows a section line SL which runs parallel to the ordinate (vv line) vv and intersects the abscissa (hh line) hh at approximately -2.5 °.
    FIG. 5 shows a luminous intensity curve 5 which characterizes the second unmodified total light distribution AF and was taken along the sectional curve SL. The luminous intensity curve 5 represents a dependency of the luminous intensity values in candelas [cd] with the low beam module 105 and high beam module 106 illuminated simultaneously on a parameter which is determined by the choice of the sectional curve SL. Since the sectional curve SL in Fig. 4 is parallel to the vv line, the parameter in Fig. 5 is equal to the angle plotted on the vv line in degrees. The luminous intensity curve 5 in this example of the total light distribution AF has a rise area consisting of a flat part 54, a steep part 52 and a transition area 55, and a maximum 53 and a slope area 50. The first flat rising region 54 is characterized by a weak gradient, the second steep rising region 52 having a high gradient. The shape of the transition region 55 reflects how much the gradient function (not shown) changes in this region. As a measure of this change serves the radius of curvature rl along the transition region 55th
    6 schematically shows a third total light distribution AF 'according to the invention, which is produced by simultaneous illumination of the light modules 105, 106 and 107 shown in FIGS. 12 and 13 and as superposition of the low beam distribution A, the segmented partial high beam distribution F and the second partial light distribution according to the invention Z results. Furthermore, FIG. 6 shows a section line SL which runs parallel to the w-line and intersects the abscissa (hh-line) at approximately H = -2.5 °, for example. The arrangement of the second partial light distribution Z according to the invention in FIG. 6 differs from its arrangement in FIG. 3. On the one hand, it is entirely conceivable that the partial light distribution Z according to the invention is not contained in the low-beam distribution but partially overlaps it. On the other hand, in a preferred embodiment of the invention, the partial light distribution Z can adjoin the hh line from below.
    7 shows two light intensity curves 5, 6 applied simultaneously. The first light intensity curve 5 has already been discussed in the description of FIG. 5 and is here to illustrate the differences between the unmodified (second) total light distribution AF and the modified (third) total light distribution AF 'dashed. The second luminous intensity curve 6 (solid line) characterizes the third modified total light distribution AF 'and was taken along the sectional curve SL. The second luminous intensity curve 6 represents a dependency of the luminous intensity values in candelas [cd] on simultaneously illuminating low-beam module 105, high-beam module 106 and additional light module 107 according to the invention by a parameter which is determined by the choice of the sectional curve SL. Since the sectional curve SL in Fig. 6 is parallel to the vv line, the parameter in Fig. 7 is equal to the angle plotted on the vv line in degrees. The second luminous intensity curve 6, in this example, of the total light distribution AF 'has a rise area consisting of a flat part 64, a steep part 62 and a transition area 65, and a maximum 63 and a slope area 60, the slope area 60 the second light intensity curve 6 with the slope region 50 of the first light intensity curve 5 almost completely coincides. Again, the radius of curvature r2 along the transition region 65 is a measure of the change in the gradient function of the third total light distribution AF '. Since the transition region 65 of the second light intensity curve 6 is less curved than the transition region 55 of the first light intensity curve 5, the minimum value of the radius of curvature r2 is along of the transition region 65 is greater than the minimum value of the radius of curvature rl along the transition region 55. This indicates that the transition 65 is "softer" than the transition 55 and subjectively more pleasing to the driver.
    FIGS. 8 and 9 illustrate the above-discussed differences between the typical unmodified second total light distribution AF and the third overall light distribution AF 'modified according to the invention. Both figures represent an isolux line diagram which corresponds to a corresponding light distribution recorded on a measuring screen erected at a specific distance perpendicular to the optical axis of the light modules. Each contour - called the isolux line - describes a set of points in which the light intensity assumes a specific light intensity value that is the same for all points of this set. The distance between the contours measured along a particular section describes how much the gradient changes along that section. The distance between the second Κ2 and the third K3 as well as between the third K3 and the fourth K4 contour measured along the vertical line H = 0 ° (vv line) in FIG. 8 is visibly smaller than that in FIG the vertical line H = 0 ° (w-line) measured distance between the second K2 'and the third K3' and between the third K3 'and the fourth K4' contour, and reflects the reduction of the gradient. For this reason, the total light distribution AF 'produced with the third light module according to the invention is perceived by the driver to be more pleasant than the typical total light distribution AF.
    The corresponding luminous intensity curves 5, 6 and the associated gradient functions are shown in FIG. 10 and FIGS. 11a and 11b. The magnitude of the minimum value of the gradient in FIG. 11a is about 0.5 and is greater than the magnitude of the minimum value of the gradient in FIG. 11b, which is about 0.25.
    In order to produce the second partial light distribution according to the invention, various arrangements and configurations of the third light module 107 are conceivable. Preferably, the third light module 107 is associated with a reflector, as shown in Fig. 12 and Fig. 13. It is advantageous to arrange the third light module 107 with the first light module 105 and with the second light module 106 in a vehicle headlight housing 101, as shown in FIG. 12. However, depending on the size of the individual light modules, this overall arrangement could violate ECE regulations. Therefore, it is quite conceivable to arrange the third light module 107 outside of the vehicle headlight housing. This arrangement is shown in FIG.
    The invention has been described with reference to a segmented partial high-beam distribution for which the invention is particularly advantageous because a segmented partial light distribution has a lower edge 25 at which the overall high-beam distribution has a particularly strong gradient.
    In principle, however, the invention can also be used in connection with non-segmented partial high beam distributions.
