    LIGHT ARRANGEMENT FOR VEHICLES
    The invention relates to a lighting arrangement for vehicles, with two light guides and a light source, wherein the light source is assigned to two light guides to feed light, the light guide for guiding the light and for emitting light due to provided on inner sides of the light guide impurities and the light guides are curved apart from the common feed point in a fork.
    Light sticks are increasingly used in vehicle construction, wherein light, e.g. of light-emitting diodes, is fed at an end face in a light stick. The light is inside the boundary walls of the most circular, but possibly also another, e.g. elliptical cross-section light guide totally reflected, but at the impurities, e.g. are formed prismatic, deflected and radiated substantially at the opposite side of the impurities. The geometry of the glow sticks is often determined by design specifications in automotive construction, whereby the desired contours can often no longer be realized by a single light stick and in many cases it is necessary aufzuschabel a light stick in two branches. Such lighting arrangements are considered within the scope of the invention.
    In the prior art, the beam splitting by an air prism, such. according to DE 101 58 336 B4, or by splitting an optical fiber into a bifurcation (" Beamsplitter "), e.g. in DE 101 62105 A1.
    In both cases, problems arise with respect to a uniform luminance along the light guide, especially in the bifurcation, depending on the viewing angle un-controllable light spots, but especially dark spots occur. In the case of beam splitting by an air prism, this is to be regarded as a bright spot ("spot") on oblique viewing. Luminance inhomogeneities in the two light guide branches, in particular in the beam section, occur and the efficiency is reduced by losses due to the incomplete deflection of the light by 90 ° reduced at the air prism. When splitting through a bifurcation, too little light is often coupled out in this area because of the shallow angle of incidence of the light.

    It is an object of the invention to avoid the aforementioned inhomogeneities of the luminance as much as possible, so that the entire luminaire appears evenly lit and produces a pleasing luminous image.
    This object is achieved with a lighting arrangement of the type mentioned, in which according to the invention in the region of the fork on the mutually facing outer surfaces of the two light guide bead-shaped radiating points are formed.
    Thanks to the invention enough light can be radiated in the critical bifurcation, where it is in the hand, over the diameter, more generally on the geometry of the bead-shaped radiating points and the impurities brightness according to the requirements, especially with regard to the curvature of the light guide to control. It should be noted that the lighting arrangement according to the invention can produce a light pattern which complies with legal regulations such as ECE, SAE, CC and the like.
    In expedient embodiments, provision is made for the bead-shaped emission spots to extend essentially in the circumferential direction of the light guides and / or substantially parallel to one another.
    A further improvement of the appearance may result if a wedge-shaped luminous body is arranged in the fork, wherein two sides of the luminous body are adapted to the curvature and the diameter of the optical fibers and are nestled on them, leaving an air gap. It is advantageous if the third side of the luminous body is concavely curved and passes over substantially continuously running in the curvature of the light guide. Thanks to these features, the light guide sections appear uniform to a viewer and give a pleasing appearance.
    In terms of good light crossing in the luminous body, it is recommended that bead-shaped radiating points are formed on the two sides of the luminous body facing the light guides, which are expediently offset in addition to the bead-shaped radiating points of the two light guides. PI2409 • * ♦ · • · · »··· * · *« * ......- S- ·
    A structurally simple and expedient variant is characterized in that the bead-shaped emission points of the light guides and / or the luminous element are formed as elevations.
    In general, it is recommended that the impurities are formed as prismatic structure.
    It is also advisable that the light guides at the feed point have a common light entry surface, wherein the two light guides can be formed integrally at the feed point with advantage. It has proved to be advantageous if the distance a of the centers of the two light guides at the feed point between 1/4 and 3/2 of the radius a of the light guide.
    The invention together with further advantages is explained in more detail below by way of example embodiments, which are illustrated in the drawing. In this show

    9 shows in detail the fork region similar to the view of FIG. 8 with an oblique section through the luminous element and the luminous rods and the marked course of two exemplary light beams, FIG.
    Fig. 10 shows the detail X of Fig. 9 and
    11 shows the detail XI of FIG. 9.
    Referring now to the drawings, in which Fig. 1 and 2 shows an embodiment of a erfindimgsgemä Shen luminous arrangement 1, which has two light guides 2, 3, a light source 4 and optionally a luminous element 5. The light guides 2, 3 have a specific shape with different curvatures, this shape being determined by the intended use, and it is, of course, possible for both light guides to have the same shape or to be mirror-symmetrical to one another. For example, the light guide should follow the contour of a headlight and frame it in the form of a glowing in operation band. In known manner, the light guides 2, 3 have substantially on their insides a structure of impurities 6, which are generally formed as prisms or prism-like. In the example shown, the light guides 2, 3 have a-most preferred-circular cross-section, but the cross-section could for example also be elliptical or otherwise shaped.
    Coming now to FIGS. 3 to 6, it can be seen that the light guides 2, 3 have a common light entry surface 7 at a light feed point, wherein the two light guides 2, 3 are integrally formed at the feed point in the illustrated embodiment and the distance a their centers there is about 1.2 times their respective radius r (FIG. 6). In extreme cases, the coupling-in points of both light guides can also coincide, i. the distance a is equal to zero. The integral nature of the feed point is also not a requirement, i. the Lichtleier 2,3 may be separated from each other at the feed point. It is understood that the light source, as known to those skilled in the art, can also be embodied differently and is not limited to the use of LEDs.
    Starting from the common light entry surface 7, the two light guides 2, 3 branch in a fork G and then take separately each of the well-visible in Figs. 1 and 2 courses. In the region of the fork G bead-shaped radiating 8 are formed on the mutually facing outer surfaces of the two light guides 2, 3, whose example arrangement and shape in detail in FIGS. 9 to 11 can be removed. In the exemplary embodiment shown, the emission spots 8 are designed as elevations and extend essentially in the circumferential direction of the light guides and / or substantially parallel to one another. In principle, however, bead-shaped depressions can also be used as emission points. It should be noted that the term " outer surfaces " is not intended to be limiting in any way, but merely to indicate that this " outer surface " at least approximately the impurities 6 are opposite and thus the light is emitted from these surfaces. In general, it should be noted that relationships such as " front ", " rear " etc. always refer to the installation position of the light assembly.
    Thanks to the bead-shaped radiating points 8 enough light can be emitted in the critical region of the fork G, where you can control the brightness to the desired extent over the diameter, more generally on the geometry of the elevations 8.
    In the sense of a further improvement of the illuminated image of the luminous body 5 can be used, which is arranged in the fork G, wherein two sides of the wedge-shaped in principle, the filament 5 of the curvature and the diameter of the light guides 2, 3 are adapted and nestled at this. In this case, an air gap must be left between the luminous element 5 and the light guides 2, 3, which lies in the range between a few 1/100 mm up to the mm range. The third side of the luminous element 5 is, as best shown in FIGS. 4 and 5, concavely curved and merges substantially continuously into the curvature of the optical waveguides 2, 3. In the embodiment shown, the luminous body 5 is concave on the third side, but it should be clear that the course of this page depends on the course of the two light guides 2, 3 and the third side can accordingly also be straight or convex. In order to counteract a shallow entrance angle and thus better penetration of light beams into the PI2409 PI2409 * * Μ ·· * »···· *» »» * * ·· * · * · «*» «« · * · · · · *** · »» · · · · · · · · · · · »» »
    To cause the luminous element, bead-shaped radiating points 9 are formed on the two, the light guides 2, 3 facing sides of the filament 5, which in principle the same bead-shaped radiating 8 of the light guide 2, 3 and therefore can also be designed as a bead-shaped depressions. The bead-shaped radiating points 9 of the luminous element 5 are offset from the bead-shaped radiating points 8 of the two light guides 2, 3; the elevations 8, 9 mesh, so to speak, like a comb. The term " wulstför-mig " should not be limited to the illustrated " round " Cross sections of these radiating 8 or 9 be understood. Whether a rather round or prismatic structure of these radiation spots is used depends in each case on the desired radiation characteristic.
    As can be seen, the emission spots 8 of the light guides 2, 3 extend over only part of the circumference, usually within a preferred range of 5 ° to 180 °. Furthermore, neither the emission spots 8 of the light guides 2, 3 nor the emission spots 9 on the luminous body 5 must be designed identically; they can also be of different nature. Thus, for example, in the case of round radiation spots, their radius can be varied and also the Winkler extension over the circumference of the light guides, and also their distances can be different. For example, the density of the emission spots 8, 9 in the vicinity of the coupling-in point of the light source can be large and decrease from here along the light guide, which also applies mutatis mutandis to the emission points 9 of the luminous element 5. It can be provided as radiation points and elevations on the light guides 2, 3 and Vertiefxmgen on the luminous body 5 or vice versa. For example, beam paths are shown in FIGS. 9, 10 and 11. On the luminous body 5 also other optical means may be provided to influence the emitted beam.
    The filament 5 carries in this embodiment, a first and a second fastener 10 and 11, said fasteners with corresponding fasteners 12 and 13, sitting in the inner fork region on the two light guides, can cooperate. To facilitate assembly, the fasteners 10 to 13 may be configured in the sense of a snap connection. In view of the above-mentioned air gap, the fastening means must be designed and dimensioned so that this air gap is maintained. Of course, the luminous element 5 can also be held in place in any other way, e.g. by gluing, but care should be taken that the fasteners do not affect the illumination. # * PI2409 * ·
    In practice, a lighting arrangement described above is provided in a housing which also has a sealing cover glass. In addition, an aperture can be arranged in front of the light guides, which is either clear, transparent (translucent) or designed as additional optics, in order to achieve, for example, a further increase in homogeneity or additional optical effects.
