    light guide
    The invention relates to a light guide element for a light unit or a motor vehicle headlight, wherein the light element has at least one Lichteinkoppelbereich for coupling light with at least one light source and the light guide further comprises at least one Lichtauskoppelbereich for coupling the light. The invention also relates to a light unit or a motor vehicle headlight with at least one light source with such a light guide.
    Various types of light guiding elements for bundling light are known. The light from one or more light sources, e.g. Light-emitting diodes (LED), halogen, xenon or discharge lamps are coupled into the light-guiding region in the light-guiding element and then reach the light-coupling region in various ways. The light exiting there then produces a light function, e.g. Position light, daytime running light (DRL) or flashing light.
    AT 009 091 U1 shows a light-guiding element with a light-coupling region and a light-coupling region, wherein light-conducting rods are provided between the regions, which fan-shaped propagate and have different cross-sections. The Lichtleitstäbe are designed as recesses in the light guide.
    EP 1895228 A1 shows a device with three zones, the first zone serving to couple in light, the second zone distributing the light uniformly and the light exiting in the third zone. Corresponding optical elements in the second zone thereby ensure a uniform luminance.
    WO 2011/021135 A1 shows a lens arrangement for a light source, which rises in the shape of a cup and consists of strip-shaped light-conducting elements. The light of a light source - e.g. an LED - is distributed over the light guide elements in the direction of a plate-shaped light exit surface. DE 698 33 421 T2 describes a light emission optics for vehicle signal lights, comprising a plate of translucent material, in the openings with concave and convex P12181
    -f xen surfaces are designed, which act as cylindrical lenses and allow a uniform light distribution over the translucent plate.
    A disadvantage of these known solutions is, in particular, that the light emerging via the Lichtauskop- pelbereich is usually distributed inhomogeneous for design reasons, which in particular when using light sources with a particularly pronounced Hauptab-beam direction, such. LEDs, the case and unwanted. As a result, the light passing over the light coupling-out area acts unevenly bright or the light source increasingly forms. Frequently, the known light-guiding elements are difficult to manufacture with favorable injection-molding methods, since the small-dimensioned recesses and clearances in the mold-parting region can cause burrs which lead to considerable light losses. Accordingly, then the tools in production and operation (maintenance costs) are relatively expensive.
    It is therefore an object of the invention to provide a light guide which produces a uniform light distribution regardless of the light source used.
    This object is achieved with an initially mentioned light guide according to the invention, that between the Lichteinkoppel- and the Lichtauskoppelbereich a beam portion is disposed at which the coming of Lichteinkoppelbereich part of the light guide is divided into at least a first light guide part and at least a second light guide part in each other wegführende directions extend, wherein in the spanned by the light guide portion a light-conducting connecting element is arranged, which merges on its side remote from the light guide parts side in the Lichtauskoppelbereich, wherein the optical fiber parts have on their side facing away from the Lichtauskoppelbereich optical structuring elements.
    The light guide according to the invention allows a uniform luminance depending on the light source used, since the feed into the connecting element is not directly, but via the optical fiber parts. In addition, the amount of light emerging in the light coupling region can be optimally adapted by appropriate design of the connecting element, wherein the emission characteristic of the respective light source can be taken into account. The optical structuring elements guide the incident light into the P12181
    Lichtleitstäbe or grooves in the connecting element and thus support a homogeneous light distribution. The Lichtauskoppelbereich is conveniently beautifully designed with a smooth surface / what this is possible / that thanks to the solution according to the invention, a homogenization of the light already takes place in the light guide. Of course, however, the surface of the Lichtauskoppelbereichs arbitrarily, for example, structured, running.
    The light-guiding element according to the invention allows the fulfillment of the legal regulations applicable to motor vehicle parts such as ECE, SAE and CCC and has a particularly homogeneous light distribution. Homogeneous is here understood to mean a light distribution which has no intensity jumps. However, it is not necessary that the emitted light has the same intensity everywhere; For example, the light distribution may have a maximum in the center and a decreasing intensity towards the outer areas.
    In a variant of the invention, at least one bifurcation element is provided in the beam part region at the point from which the light guide parts originate. The fork element is favorably optically thinner than the rest of the light guide. The bifurcation element can be designed, for example, as a strongly thinned point of the light-guiding element or of air, that is to say as an opening or perforated point. The bifurcation element serves to ensure the most complete possible diversion of the injected light in the light guide parts. In addition, the bifurcation element helps to prevent the light source from imaging as a direct spot in the emerging light distribution. Conveniently, lower strands are provided in the connecting element, which arise at the light guide parts and open into the light outcoupling region. In a variant of the invention, the cross sections of the lower strands are designed with different diameters. For example, the diameters may increase or decrease in one direction. As a result, the intensity distribution of the coupled-out light can be additionally designed. The lower strands can be designed, for example, as light guide rods and / or as Lichtleitrillen. Via the sub-strands, the coupled-in light can be guided into the light outcoupling area. The alignment of the light guide rods or Lichtleitrillen results in the main emission of the entire light guide. The light guide rods can be manufactured separately, structured by means of clearances or executed during injection molding. The PI2181 Λ f · ft · 9 9
    Grooves can be embossed or released after production or can be made directly during injection molding. Accordingly, the sub-strands may also be interconnected, which is immediately evident in execution as Lichtleitrillen. But even in the design as Lichtleitstäbe thin connections between juxtaposed Lichtleitstäben exist.
    In a variant of the invention, the light-conducting rods and / or light guide grooves originate at the light guide parts outside the beam part region and are designed such that they run in the direction of the light coupling-out region in the shadow region of the beam part region. The shadow area can be seen behind the bifurcation element (if present) in the direction of the beam. The light guide rods or light guide grooves therefore also extend into the region of the connecting element which is shaded by the beam part region and ensure homogeneous light distribution at the light outcoupling region of the light guide element. This prevents that the light source is reflected as a bright intensity spot, which is often a problem, especially when using light-emitting diodes.
    Advantageously, the structuring elements have a prism structure. The prism structure is designed in a known manner and directs the rays coming from the beam splitting region into the connecting element or into the lower strands (light guide rods or grooves) made there. From there, the light then enters the light extraction area and is emitted. Through skillful design of this prismatic structure, the light can be pre-homogenized. Customizable parameters of the prism structure are, for example, density and / or number and / or depth and / or width of the prisms.
    Further influencing the light distribution can be achieved if the optical fiber parts have different cross-sectional diameters. Depending on the light distribution can then be controlled, for example, by the first light guide member is provided with a larger cross-sectional diameter than the second, or vice versa.
    For better positioning of the light-guiding element, at least one supply element is provided between the light-coupling region and the beam-part region. Conveniently, the feed element is designed as a light guide. As a result, it is possible to position the light source and the light guide element completely independently of each other, since the light from the light source P12181 ··· * · φ le is fed into the beam section via the feed element. Thus, the light guide is diverse used.
    In a variant of the invention the Lichteinkoppelbereich, the beam portion and the light guide parts are made in one piece. Furthermore, the connecting element and the light outcoupling region can be made in one piece. In a further variant of the invention, the light coupling region, the beam part region, the optical waveguide parts, the connecting element and the light outcoupling region are made in one piece.
    In order to facilitate the assembly of the light-guiding element according to the invention, latching and / or referencing elements for mounting the light-guiding element are provided on the light-guiding element in the region of the light coupling region. If, for example, the light-guiding element is to be connected to a light source module, via which the light is coupled in, a fixed and simultaneously releasable fixing can be ensured by these latching and / or referencing elements, which at the same time permits optimum positioning of the light-guiding element with respect to the light sources , Accordingly, correspondingly corresponding fixing elements are then provided on the light source module (or the object with which the light-guiding element is to be connected) in a known manner. The latching and / or referencing serve further as centering and even referencing, so ensure that the light guide can be reproducibly mounted so that the desired light function is ensured, or that the required light distribution is emitted.
    Furthermore, the decoupled amount of light can be increased or the light-emitting surface and / or the illuminated surface can be increased by providing at least one additional light decoupling region in the light decoupling region according to a variant of the invention. Conveniently, at least one shell element which is open in the beam direction is provided for this purpose in the light outcoupling region, at the side of which the additional light-emitting region is remote from the light-coupling region. Advantageously, a first shell element with a first Zusatzlichtauskoppelbereich and a second shell element are provided with a second Zusatzlichtauskoppelbereich.
    The object mentioned above is also achieved by an initially mentioned light unit or a motor vehicle headlight, wherein at least one P12181
    Light guide is provided for coupling light from at least one light source. The motor vehicle headlight is used for example for generating a light function such as position light, daytime running light (DRL - Daytime Running Light) or flashing light,
    If you want to Generate position light and / or DRL, so you need white light; at flashing light yellow light. If you now combine these light functions in a single light guide system, you either need a light source that provides both colors or two different LEDs, which can then be switched optionally. Accordingly, according to a variant of the invention, the light source module is adapted to couple multicolored light into the light guide. This can be realized either by the front of several light sources or by a single light source that can emit light in multiple colors. Thus, depending on the desired light function, e.g. optionally either white and / or yellow light are coupled. Conveniently, the light source module (or its light sources) is dimmable. This means that the light sources arranged therein are dimmable and can be changed in their intensity. Thus, different light intensities can be realized, as they are e.g. be required in the various legal provisions.
    In a variant of the invention, at least one LED chip is provided in the light source module as the light source. Such light sources are known; Of course, any other known to the expert light sources can be used.
    In the following the invention will be explained in more detail with reference to a non-limiting embodiment, which is illustrated in the drawing. In this shows schematically:
    1 is a perspective view of a light guide according to the invention obliquely from the front with trim,
    2 is a perspective view of a light guide according to the invention obliquely from the front without trim panel,
    3 is a perspective view from the side,

    Fig. 5 is a sectional view of the connecting element of the light guide along the line A-A in Fig. 3, and
    Fig. 6 is a side view of a variant of the light guide element according to the invention.
    Fig. 1 shows an inventive lichtieitelement 1 in a view obliquely from the front. The light guide 1 is made for example of lichtleitendem plastic, glass or other light-conducting materials, for example by injection molding. Light from at least one light source, for example a light-emitting diode (LED), is fed in via a light-coupling region 2 and exits via a light-outcoupling region 3. The light sources, LED chips 23 in the present example, are arranged in a light source module 20 on a circuit board 22 with a corresponding contact. For example, 22 corresponding connectors for fixing the LED chips 23 may be provided in the board. The light source module 20 further includes a heat sink 21 for dissipating the heat generated by the operation of the LED chips 23.
    Basically, at least one light source is necessary, but it may be beneficial to provide several different colored light sources (or a light source that can provide multiple colors) to cover a wider range of light functions. For example, you need white light for position light and / or DRL (daytime running light), yellow light is required for flashing light. These two functions can therefore be combined either with an LED chip 23 or more LED chips in a single fiber optic system, which are then respectively switched accordingly. Conveniently, the light sources are dimmable, so that the different light intensities are achieved in accordance with the above-mentioned legal requirements.
    The light-emitting element according to the invention can be used together with such a light source module 20 in a light unit or a motor vehicle headlight.
    In Fig. 1, a major part of the light guide 1 is surrounded by a trim panel 30. It serves to minimize the leakage of spurious radiation caused by micro surface defects or the like on the light emitting element, thus ensuring a homogeneous light distribution. This also prevents light from reaching unwanted areas 1 P12181 1 P12181 * ·

    Between the Lichteinkoppel- 2 and the Lichtauskoppelbereich 3 a beam portion 4 is arranged, at which the coming of the Lichteinkoppelbereich 2 part of the light-dividing element 1 is divided into a first 5 and a second light guide member 6, which extend in directions away from each other. According to a variant, a bifurcation element 13 (see FIG. 3) may be provided at the location from which the optical waveguide parts 5, 6 originate in the beam portion 4. The fork element 13 is designed to be optically thinner than the rest of the light-guiding element 1, that is, for example, from air, that is, as an opening or perforated point. Another variant would be the execution as a highly thinned point of the light guide 1, where by the combination of thin element layer and air as the remaining part of the fork member 13, a visually thinner area is approximated. It would also be possible to carry out a different from the rest of the light guide 1, optically thinner material.
    In order to be able to arbitrarily arrange the light outcoupling region 3 with respect to the light incoupling surface 2 or the light source, a feed element 12 in the form of an optical waveguide is provided between the light coupling region 2 and the beam subregion 4 in the present exemplary embodiment. As can be seen in the side view according to FIG. 2, the feed element 12 in the exemplary embodiment shown is short and straight, but it can also be designed and arranged to be longer and twisted.
    At the light guide 1, preferably at the feed element 12 (or generally speaking near the Lichteinkoppelbereich 2), Verrastungs- and / or referencing are provided with which the light guide 1 can be installed at its intended location. The latching and / or referencing elements are designed, for example, as latching lugs which interact with corresponding corresponding elements at the place of use (for example, the light source module 20) of the light guide element 1. This compound can be solved according to the common design of locking connections. The Verrastungs- and / or Referenzierelemente 40 simultaneously serve for referencing, so for reproducible mounting of the light guide. 1
    In the embodiment, the Verrastungs- and Referenzierelemente 40 are basically the same, but can serve on the one hand by interacting with a corresponding counterpart to the light unit for fixing, on the other hand without corresponding counteracting for referencing, so for (reproducible) ensuring the desired light distribution.
    As can be seen with reference to FIG. 2, the optical waveguide parts 5, 6 extend in directions away from one another - in essence, they can span an angle of up to 180 °. The optical waveguide parts 5, 6 do not run in straight lines, but in curves - the angle between the optical waveguide parts 5, 6 is thus to be understood either as the angle, the respective rectilinear connections between the beam portion 4 and end point of the respective optical fiber part 5, 6 include as an angle between the tangents to the optical fiber parts 5,6 at certain points.
    The course of the optical waveguide parts 5, 6 can be selected according to the available installation space and the size of the span. It should be noted that the curvature of the optical waveguide parts 5, 6 still allows a total reflection of the injected light, or that it does not come to excessive light losses. Basically, the expert from the above information, a guide to the execution of the optical fiber parts 5, 6 refer.
    In the area of the light guides 5, 6, a light-conducting connecting element 7 is arranged, which merges at its side facing away from the light guide parts 5, 6 in the Lichtauskoppelbereich 3.
    The light-conducting connecting element 7 has, for example, a fan-shaped feed with lower strands which originate in the light guide parts 5, 6 and open into the light outcoupling region 3. The lower strands are executed in the illustrated embodiment as Lichtleitstäben 9. 5 shows a section through the light guide element 1 in FIG. 3 along the line A-A - between the light guide parts 5, 6, the connecting element 7 with the Lichtleitstäben 9 can be seen.
    The cross-sections of the optical waveguide parts 5, 6 and also of the individual light-conducting rods 9 with one another have substantially the same diameter in the exemplary embodiment shown. P12181 + · «· • ψ-πο: - • + • · tt ·« ·· ··· «f ··
    To influence the light distribution but also different diameters can be chosen here. For example, the diameter of the Lichtleitstäbe 9 can differ via the connecting element 7, for example, increase or decrease. To generate a maximum in the light distribution, the more centrally located light-conducting rods 9 can be made thicker or wider. Furthermore, individual light guide rods 9 can be designed with increasing and / or decreasing diameters over their length or have other changes in their cross section over their course. For example, a light guide rod 9 at the location of its origin on the light guide part 5, 6 have a narrow diameter, which then increases in the direction of the Lichtauskoppelbereichs 3.
    Also, by varying the cross-sectional diameters of the optical fiber parts 5, 6, a change of the light distribution can be effected, e.g. in that the diameter of the first optical waveguide part 5 is chosen to be larger than the diameter of the second optical waveguide part 6.
    Of course, the connecting element 7 can also be designed differently light-conducting by other embodiment of the lower strands, for example by the provision of Lichtleitrillen, combinations of grooves and rods and similar, known in the art solutions. The lower strands can also have connections with each other, which is evident, for example, when executed as Lichtleitrillen. But even in the execution as Lichtleitstäbe connections between adjacently arranged rods may exist, which may be due to manufacturing, for example. The cross sections of the lower strands may be circular, in principle also polygonal or angular or carried out in any other suitable manner. Square construction can cause light loss at the corners and edges, which is why the round or oval shape is preferable.
    The orientation of the lower strands or the Lichtleitstäbe 9 defines the Hauptabstrahlrich-direction of the entire light guide element 1 and can therefore be made suitable depending on the application. The Lichtleitstäbe 9 are designed so that they extend in the direction of the Lichtauskoppelbereichs 3 in the shadow area 10 of the beam section 4: In the beam section 4 of the Lichteinkoppelbereich 2 coming part of the light guide 1 is completely divided into the light guide parts 5, 6 - in the main beam direction is created by behind the beam portion 4 a shaded part.

    This has the advantage on the one hand that an increased light intensity is prevented in the region where the light source is coupled into the light guide element 1 - when using a light emitting diode, a massively increased circular light intensity can occur which disturbs the homogeneous luminance of the light guide element 1. On the other hand, but caused by the shaded part again a disturbance in the luminance, which is resolved by the above-described embodiment of the lower strands (Lichtleitstäbe 9).
    Therefore, the light emitting rods 9 are designed so that they arise outside the beam portion 4 and bent in the direction of the Lichtauskoppelbereichs 3 in the shadow region of the beam portion 4. The Lichtleitstäbe 9 therefore open evenly into the Lichtauskoppelbereich 3, whereby a homogeneous luminance of the light guide 1 is achieved.
    The light fed in at the light input region 2 passes via the feed element 12 (if present) to the beam section 4, where the light is conducted into the optical waveguide parts 5, 6. By optical structuring elements 8 (see Fig. 3) in the light guide parts 5, 6, the light is then introduced into the connecting element 7 and the Lichtieitstäbe 9 and exits from there via the Lichtauskoppelbereich 3 again.
    The optical structuring elements 8 are arranged on the side facing away from the Lichtauskoppelbereich 3 side of the optical waveguide parts 5, 6. The structuring elements 8 are designed as a prism structure 11 - that is, as a series of prisms - executed; Other embodiments, with which the light can be passed in accordance with the connecting element 7, are possible. By skillful design of this prism structure 11, the light can already be pre-homogenized. Customizable parameters of the prism structure 11 are, for example, number and / or depth and / or width of the prisms.
    The Lichtauskoppelbereich 3 is constructed according to the illustrated embodiment with a smooth surface, which is often advantageous for design reasons. However, the light extraction area 3 can also be designed differently, for example in order to achieve a higher light output, to increase the illuminated area or the light-emitting area. 6 shows such a variant in which a light-guiding element 1 according to the invention can be seen from the side (this view corresponds to the view from above in the installed state). In Lichtauskoppelbereich 3 two Zusatzlichtauskoppelbereiche 51, 53 are provided, which as PI2181
    in the beam direction open shell elements 50, 52 are executed, at the side facing away from the Lichteinkoppelbereich 2 side, the Zusatzlichtauskoppelbereiche are arranged. The first shell element 50 with the first additional light outcoupling region 51 and the second shell element 52 with the second additional light outcoupling region 53 are arranged on opposite sides of the light-guiding element 1.
    The provision of the auxiliary light output regions 51, 53 increases the illuminated area, which is advantageous for reasons of better visibility (for example in daytime running light). The illuminated area is determined by law for certain light distributions and may not fall below a limit.
    The additional light output regions 51, 53 may be designed with a smooth surface but also have an additional structuring in order to increase the light-emitting surface or to influence the amount of light emitted via these regions.
    Advantageously, the entire light guide 1 is made in one piece, Lichteinkoppelbereich 2, beam portion 4, optical fiber parts 5, 6, connecting element 7 and Lichtauskop- pelbereich 3 thus form a unit. Alternatively, only light input region 2, beam portion 4 and the light guide parts 5, 6 are made in one piece, or only connecting element 7 and light guide parts 5.6.
