    Furthermore, the invention relates to a vehicle headlight with a lighting device according to the invention and a motor vehicle with a lighting device according to the invention and / or a vehicle headlight according to the invention.
    Lighting devices of the type mentioned above are e.g. known from headlamps, in which two light sources are mounted in front of a reflector assembly, wherein the reflector assembly has different areas, which are provided to fulfill different lighting functions. For example, headlamps have become known in which a low-beam source and a high-beam source are mounted in front of a one-piece reflector arrangement, wherein the reflector arrangement for generating two different light distributions, namely a low-beam distribution and a high beam distribution, has two different reflector areas. In the above arrangement, it is especially important to avoid crosstalk from the low beam to the high beam, which can be achieved by appropriate design measures. A spatial and structural separation of individual reflector areas to implement different light distributions leads to restrictions on the size of the lighting device, which also involves limitations in its design.
    An object of the invention is to provide a lighting device that can be designed largely freely in shape and is suitable for generating at least two mutually different light distributions.
    This object is achieved with a lighting device of the type mentioned in the present invention, the total reflection surface of the reflector is at least partially composed of alternately juxtaposed first and second reflection surfaces, wherein the first and the second light source are arranged in such an area lying in front of the reflector area, that their radiated light is at least partially irradiated against the reflector against the direction of the optical axis of the reflector. The lighting device according to the invention is not subject to any particular restrictions with respect to its size. By assembling the total reflection surface of the first and second reflection sub-surfaces, it is possible to realize two or more light functions by means of a single reflector as well as the reflector associated light sources. The total reflection area can be significantly increased compared to conventional reflectors. In addition, the arrangement of the light sources in front of the reflector, in particular in the case of use for a vehicle headlamp, enables improved cooling of the light sources, since the area in front of the reflector can be closed, for example, with a cover plate, via which heat emitted by the light sources can be released to the surroundings ,
    In addition, further reflection sub-areas may be arranged between the first and second reflection sub-areas or vice versa. The term "optical axis of the reflector" is understood to mean an optical axis that is oriented in the main emission direction of the reflector The first and second light functions do not necessarily have to be different from each other, however, the light distributions generated by the respective light source and the associated reflection surface This means that, for example, the first light distribution and the second light distribution can each form part of a total light distribution, for example, it is conceivable that the first light distribution and the second light distribution together produce a low-beam distribution - the first light distribution and the first light distribution second light distribution in itself therefore constitute partial light distributions.
    The term "a number of" in the context of this disclosure, unless otherwise stated, means a number which is at least two and may be two, three, four or more, in particular six, eight, ten, twelve or more than twelve In view of this disclosure, those skilled in the art will be able to select the number of respective elements according to an application.The term "total reflection area" refers to the entire area of the reflector adapted to reflect light from the light sources.
    In particular, it can be provided that the first light function and the second light function are selected from the group: daytime running light, position light, side marker light, turn signal light, low beam, cornering light, high beam, static cornering or cornering light. Those skilled in the art are aware of these light functions, the associated light distributions being specified in the relevant guidelines and standards. As an example, reference is made to Regulation No 123 of the United Nations Economic Commission for Europe (UN / ECE) - Uniform provisions for the approval of adaptive front lighting systems (AFS) for motor vehicles and Regulation No 48 of the United Nations Economic Commission for Europe (UN / ECE) - Uniform conditions for the approval of vehicles with regard to the installation of lighting and light-signaling devices. In addition, it may be provided that the first and the second light function deviate from one another, wherein in principle all permutations or combinations of said functions are conceivable. In particular, the following combinations can be implemented particularly advantageous: daytime running light / position light; Daytime running light / side marker light; Daytime running light / direction indicator light or flashing light; Direction indicator light / position light; Turn signal light / side marker light; Dipped beam / cornering light; High beam / cornering light; Dipped beam / static cornering light; static cornering light left / static cornering light right; or also a specific combination of individual segments of a matrix-segmented lighting device, in which the light distribution generated by the lighting device is composed of individual segments, e.g. could be combined as follows: high beam / low beam matrix segment a / high beam / low beam matrix segment.
    In addition, provision may be made for the first and / or second reflection sub-areas to have microstructures which are set up to deflect light toward a third light distribution (selected from the light distributions mentioned above).
    In a particularly favorable and simple embodiment of the invention it can be provided that the total reflection surface consists exclusively of juxtaposed first and second reflection sub-surfaces.
    Alternatively, it may be provided that the total reflection surface has at least one third reflection sub-area, preferably a number of third reflection sub-areas, for generating a further light distribution.
    In particular, it can be provided that the at least one third reflection sub-area of the first and / or the second light source is turned to.
    It can also be provided that the lighting device has a third light source, and the third reflection sub-surface of the third light source is facing.
    Additionally or alternatively, it may be provided that the lighting device has a light sensor for checking the light function of at least one of the light sources, wherein the light distribution generated by the at least one third reflection sub-area is formed and the light sensor is arranged such that the at least a third Reflected surface irradiation light distribution on the light sensor. This light sensor can be connected to an evaluation unit, for example, which monitors the state of the lighting device and, if it concludes that it has a faulty state, sets appropriate measures, such as an error indication.
    To implement a third light function, it may be provided that the light distribution generated by the at least one third reflection sub-area is a light distribution of a light function selected from the following group: daytime running light, position light, side marker light, turn signal light, low beam, cornering light, high beam, static cornering light, cornering light.
    In a particularly expedient embodiment of the invention, it can be provided that individual reflection sub-areas, in particular the first and second reflection sub-areas, are strip-shaped and arranged next to one another, whereby strips arranged next to one another are connected to one another. The connection of the strips can be done either directly with each other or via other intermediate strips, such as strips of a third reflection sub-surface.
    In order to prevent over-talk of the light emitted by the individual light sources, it may be provided that the first light source at first Einstrahlwinkeln and the second light source at second Einstrahlwinkeln radiate to the respective reflection sub-areas, each reflection sub-surface has an inclination angle, the respective angle of incidence of unassigned light source exceeds, wherein the angle are based on the optical axis of the reflector. In this case, the light sources can be arranged, for example, at an angle between 20 ° and 75 ° with respect to the optical axis. The arrangement transverse to the optical axis of the reflector allows a short construction of the lighting device in the direction of the optical axis of the reflector.
    In addition, it can be provided that the lighting device has an imaging optics, which is downstream of the reflector for imaging at least a portion of the reflected light from the reflector. The imaging optics can be designed as a projection lens or, for example, as a cushion optic.
    In addition, it can be provided that the imaging optics has microstructures for selectively influencing the light distribution emitted by the imaging optics.

    Alternatively, it may be provided that the reflector is integrally formed with a light-conducting body, which comprises the imaging optics, in that the reflector is formed on a light-reflecting end portion of the light-conducting body. This embodiment is therefore particularly compact, wherein the one-piece design can cause a largely caused by thermal expansion or mechanical shocks incorrect positioning of the reflector with respect to the imaging optics.
    It may be particularly favorable if individual reflection sub-areas, in particular the first and second reflection sub-areas, are formed as juxtaposed strip-shaped areas on the surface of the end portion, wherein the first and the second reflection sub-areas are inclined to each other. Depending on the angle at which the light is incident on the respective reflection sub-areas, the inclination of the reflection sub-areas with respect to the incident light may already be sufficient to allow total reflection. Unless the inclination of the surfaces with respect to the light source is sufficient to allow total reflection, it may be beneficial if the strip-shaped surfaces are coated with a light-reflecting layer. In particular, the respective reflection sub-areas may be inclined in such a way that only certain reflection sub-areas are "visible" or illuminatable for the respective light source, for example the first reflection sub-areas may be arranged such that the second reflection sub-areas are in the shadow of the first reflection sub-areas from the point of view of the first light source Likewise, the first reflection sub-areas can also be in the shadow of the first reflection sub-areas as viewed from the second light source.
    In addition, it can be provided that individual reflection sub-areas, in particular the first and second reflection sub-areas, have microstructures for selectively influencing the light distribution emitted by the reflection sub-areas.

Furthermore, the lighting device comprises a first light source 3 'and a second light source 3 "for irradiating light onto the reflector 2, wherein the first and the second light source at least in a direction normal to the optical axis x of the reflector 2 - in the present case in the direction the axes y and / or z - are spaced apart.
    The total reflection surface 2a of the reflector 2 has a number of first reflection sub-areas 2a 'facing the first light source 3', which are arranged to image the light irradiated by the first light source 3 'in the form of at least one first light distribution of a first light function. The total reflection surface 2a of the reflector 2 additionally has a number of second reflection sub-areas 2a "facing the second light source 3", which are configured to image the light irradiated by the second light source 3 "in the form of a second light distribution of a second light function, the first light distribution As can be seen from FIG. 1, the total reflection surface 2a of the reflector 2 is at least partially composed of alternately juxtaposed first and second reflection sub-areas 2a 'and 2a ", wherein the first and second light sources 3' and 3" in such a way arranged in front of the reflector 2 area are arranged so that their radiated light at least partially against the positive direction (which in the case of use of the lighting device in a vehicle headlamp with the forward direction of the vehicle coincides) of the optical axis x of the reflector 2 on the R eflektor 2 is blasted.
    The arrangement of the light sources 3 'and 3 "and the reflection sub-areas 2a' and 2a" are configured so that, for example, one of the following light functions can be implemented: daytime running light, position light, side marker light, flashing light, low beam, cornering light, high beam, static cornering light, etc In the embodiment according to Figure 1, the total reflection surface 2a is composed exclusively of juxtaposed stripe-shaped first and second reflection surfaces 2a 'and 2a ", with adjacent reflection surfaces adjacent to each other and connected to each other Direction of the x-axis, it can be provided that the light sources 3 'and 3 "are arranged transversely to the optical axis x. For example, they may be arranged at an angle between 20 ° and 75 ° with respect to the optical axis x.
    In Figure 1, an imaging optics 4 is also shown, which is designed in the present example as a projection lens and the reflector 2 for imaging the reflected light from the reflector 2 is downstream, as indicated by exemplary light beams LS. The reflector 2 is formed in the embodiment of Figure 1 as a separate optical component.
    FIG. 1 a shows a detail of a first reflection subarea 2 a 'in a detailed representation. It can be seen here that the reflection sub-area 2a 'has microstructures 5 for purposefully influencing the light distribution emitted by the reflection sub-area 2a'.

Also in this embodiment, the first and second reflection portions 2a 'and 2a "are formed as juxtaposed strip-shaped surfaces on the surface of the end portion 6a, respectively, with the first and second reflection portions 2a' and 2a" inclined to each other. By the inclination of the surfaces with respect to that by the light sources 3 'and 3 "(which are preferably LEDs), the light may already be able to reach the
    Reflection surfaces are totally reflected. If the tendency to do so is insufficient, then the reflecting surfaces can also be coated with a light-reflecting layer, which can be applied, for example, by vapor deposition. The imaging optics 4 can also have microstructures 5 for purposefully influencing the light distribution emitted by the imaging optics 4, which are shown in FIG. 3 a as a detail of FIG. 3. The design of the reflective sub-surfaces in the form of juxtaposed strips is only an exemplary variant of their design. Likewise, other variants such as e.g. a step-like structure conceivable.
    3, collimator elements 7 are shown, which are arranged between the reflector 2 and the first and the second light source 3 'or 3 "for focusing the light in the direction of the reflector 2. The collimator elements 7 can be designed as separate components For this purpose, the collimator elements 7 can also be embodied integrally with the light-conducting body 6. By using the collimator elements 7, it can be ensured that the light emitted by the light sources is incident on the reflector 2 or the reflection sub-areas at a predeterminable angle, which can be ensured, for example in that all light incident on the reflector 2 by the light sources is totally reflected on the inclined surfaces.
    The imaging optics 4 can be designed, for example, as a lens but also as a so-called "cushion optic", which consists of a multiplicity of pillow-shaped structures arranged next to one another.
    With the lighting device 1 according to the embodiments shown different light functions can be realized in a simple manner using a single reflector. Thus, the first light source, for example, a low-beam function and the second light source take over the cornering function. By way of example, the following combinations are cited, where combination pairs are associated with a slash "/" and different pairs are separated from each other by a semicolon: daytime running light / position light; daytime running light / side marker light;
    Daytime running light / flashing light; Flashing light / position light; Flashing light / side marker light; Dipped beam / cornering light; High beam / cornering light; Dipped beam / static cornering light; static cornering light left / static cornering light right; High / low beam matrix segment a / high beam / low beam matrix segment b.
    4 shows a sectional view of a vehicle headlight according to the invention with a lighting device 1 according to the invention. The light sources 3 'and 3 "are arranged in the vicinity of a cover disk 9 in the front region of the vehicle headlight mainly against the cover 9, whereby the heat can be directed firstly effectively outward and secondly can be used to counteract fogging or icing of the cover and other cooling measures such as fan can be omitted.
    FIG. 5 shows a detailed representation of a beam path of a reflector 2 of the lighting device 1 according to the invention. In order to prevent crosstalk of the light emitted by individual light sources 3 'and 3 ", provision is made for the first light source 3' to be at first injection angles α 'and the second one Light source 3 "under second Einstrahlwinkeln α" on the respective reflection part surfaces 2a 'and 2a "radiate, each reflection part surface 2a' or 2a" an inclination angle ß 'or ß ", the respective Einstrahlwinkel α' or α" of unassigned light source 3 "and 3 'exceeds, wherein the angles are based on the optical axis of the reflector. In other words, this means that the first reflection sub-areas 2a 'are associated with the first light source 3', and due to the different spatial position of the individual reflection sub-areas 2a ', each reflection sub-area 2a' is at a different angle α '(each reflection sub-area 2a' is thus different Incident angle α 'and inclination angle ß' associated - for a better overview, the angle only to a single reflection part surface 2a 'provided with reference numerals) with respect to the first light source 3' occupies. Each reflection sub-area 2a 'is inclined so that it can not be irradiated by the second light source 3. "For example, the first reflection sub-area 2a', which is assigned the reference symbol β 'in FIG. 5, is inclined less than the angle of incidence α". As a result, irradiation of the respective first reflection sub-area 2a 'by the second light source 3 "is prevented. The same applies analogously to the second reflection sub-areas 2a ".
    In view of this teaching, one skilled in the art will be able to arrive at other, not shown embodiments of the invention without inventive step. The invention is therefore not limited to the embodiments shown. Also, individual aspects of the invention or the embodiments can be picked up and combined with each other. Essential are the ideas underlying the invention, which can be performed by a person skilled in the knowledge of this description in a variety of ways and still remain maintained as such.
