    FIG. 2, together with FIGS. 3a, 3b, shows a light module 2 according to the invention, as used in FIG. In this case, the light module 2 comprises a number of light sources 4, which are arranged on a light source carrier 5, and which couple light into an upstream intent optical system 6. The attachment optics 6 can be fastened to the light source carrier 5 by means of an attachment optics carrier 7, so that the light sources 4, the light source carrier 5, the attachment optics 6 and the attachment optics carrier 7 form a light source carrier. Form assembly 8.
    The attachment optics 6 has five light guide bodies which are inserted into the attachment optics carrier 7. In each of these five light guide coupling in this example in each case two LED light sources each consisting of a light emitting diode. This light emerges from the light-conducting bodies via the light exit surfaces of the light-guiding bodies and in each case forms a segment in the light image.

    Looking now at Figures 5 ~ 7, the following can be seen: The light module 2 has clamping means in the form of two clamping screws 12, by means of these clamping screws 12, the heat sink 11 can be screwed to the United carrier 10, as shown in Figure 7 is shown. As a result, the assembly 8 is clamped between the heat sink 11 and the lens carrier 10, in particular - as can be clearly seen in FIG. 5 - in this case the intent optical carrier 7 is clamped between these two components.
    If this clamping is now achieved so far that the heat sink 11 and the lens carrier 1.0 are still connected to each other (loosened), the intermediate assembly 8 becomes displaceable, essentially parallel to the heat sink 11. In principle, any displacement (FIG. left - right, up - down) conceivable, combinations of these displacement possibilities, in the embodiment shown a horizontal displacement (left - right) is realized.
    By shifting the assembly 8, the light distribution generated by this light source assembly 8 can be aligned accordingly, finally, in the correct, desired position, the light source assembly 8 can be fixed relative to the assembly support (heat sink) 11 ,
    The clamping screws 12 connect the module carrier 11 and the secondary optics carrier 10 directly, without being contacted by these clamping screws 12, the assembly 8, as can be seen well in Figure 6 in conjunction with Figure 7, is. The heat sink 11 has corresponding openings 12 ', in the lens carrier 10 are corresponding threads 12 " intended.
    In the specific embodiment of the invention as shown in the figures, it is provided that the secondary optics carrier 10 forms a guide 110 for the light source assembly 8, in which this light source assembly 8 is displaceable, in particular laterally. relative to the mounting position of the light module 2 horizontally (left - right) is slidably mounted.

    Thus, after setting the correct position, in addition to the clamping, the light source assembly 8 can be fixed with the assembly screws 13 with respect to the package carrier 11 so that the light source assembly is reliably positioned even during operation of the vehicle.
    The Arreiierschrauben 13 enforce the rear side 11b of the module carrier 11 by a respective associated Arreüerschraubenöffnung Ha in the module carrier 11. Furthermore enforce the locking screws 13, the assembly 8 through a respectively associated module opening 8a, and finally in a corresponding locking screw thread 10a in the secondary optics carrier 10 can be screwed.
    The module Öifnungen 8a are formed as slots, which extend in the installed position in the embodiment shown in the horizontal direction, substantially normal to TJchtaustrittsrichtung.
    The module openings 8a are preferably formed on the attachment optics carrier 7. The light source carrier 5 has corresponding recesses 5a, so that the openings 8a are exposed.
    If one concludes FIGS. 8-10, it can be seen that for easy insertion of the light source assembly, preferably the module carrier 11 has a tool opening 14 (see also FIGS. 5 and 7) for inserting a displacement tool 20 (FIG ), by means of which the light source assembly 8 is displaceable.
    The displacement tool 20 is rotatably mounted with a tool-bearing portion 20 b, which has a circular cross-section, in the tool opening 14, which is also circular. In addition, the tool has a tool portion 20a which is eccentric, i. is arranged outside the axis of rotation 20c of the tool 20.
    This tool section 20a engages in an adjustment opening 8b (FIGS. 5-8) in the light source assembly 8, which adjustment opening 8b is arranged opposite the tool opening 14, where the adjustment opening 8b is preferably arranged on the pre-set optical support 7 as shown , 12/24 F13524 -12
    By moving the tool 20 in the tool opening of the tool moves with the tool portion 20 a, the light source assembly 8 accordingly. Concretely, by turning such an "eccentric tool", 20 implemented the rotational movement of the tool in a sliding movement of the light source assembly 8 and allows a simple and accurate displacement of the assembly. 8
    To implement the movement of the tool in a displacement movement of the light source assembly is concretely provided that the adjustment opening 8b is a LangSoeh, which extends normal to the direction of displacement and is in the displacement plane of the light source assembly 8.
    FIG. 10 shows exactly one of five light segments 40 that can be generated with a light module 2 and the two extreme positions of the light segments, which can be adjusted by corresponding displacement as described above. 13/24
