1. A light module for motor vehicles, the light module comprising:
a first laser arrangement (LS), which contains at least one laser light source (L1, L2, L3, L4) which can be modulated, the laser beam/laser beams (b1, b2, b3, b4) of which is/are directed to a pivotable micromirror (6) controlled by a mirror control (8) and from there to a light-converting means (7);
a lighting optics (9) for projecting an illumination pattern generated by the light-converting means (10) into a traffic space/roadway, as a lighting system; and
a second laser arrangement (VL), which contains at least one laser light source (H1, H2, H3), wherein its laser beam(s) (c1, c2, c3) is/are sent to the pivotable micromirror (6) controlled by the mirror control (8) and from there, via a LIDAR exit optics (21) separate from the lighting optics (9), into the traffic space/roadway, as well as having a LIDAR entry optics (14), which sends light of the second laser arrangement reflected in the exterior space to a detector (15), as a LIDAR system, wherein the angle of incidence of the laser beam(s) (b1, b2, b3, b4) of the first laser arrangement (LS) on the micromirror (6) is different from the angle of incidence of the laser beam(s) (c1, c2, c3) of the second laser arrangement (VL), wherein a scanning area, defined as the area scanned by LIDAR laser beams of the LIDAR system, and an illuminated area, defined as the area of the traffic space/roadway illuminated by the lighting optics of the lighting system, are positioned at an angle to each other, such that the LIDAR system scans diagonally to the illumination, wherein the LIDAR system and the lighting system cover or illuminate different fields of view via the lighting optics (9) or, respectively, the LIDAR exit optics (21), wherein the LIDAR exit optics (21) is designed in such a manner that the LIDAR system scans an area of the traffic space which is wider than the illuminated area of the lighting system.
