As a result, they can be projected by the secondary optics 7 as a uniformly homogeneously illuminated resulting total light distribution on the roadway in front of the motor vehicle.
  • “Homogeneously illuminated” in this context means, in particular, that the resulting total light distribution of the light module 1, in particular in the region of the transitions between the individual partial light distributions projected onto the carriageway by the secondary optics 7, has no undesired dark areas, shadows or dark lines.
  • a variation of the illuminance distribution within the resulting total light distribution is possible.

  • the resulting light distribution of the side illumination on the right is in FIG. 11 shown.
  • an activation of the other light source 3 would cause the generation of another part of the secondary light distribution in the form of a left side illumination. It is conceivable to activate both light sources 3, 4 at the same time.
  • the shape and design, in particular the light intensity distribution, the resulting side illumination can be easily and effectively changed by changing the shape and / or orientation of the Concave mirror 18 and / or the deflection mirror 17 is changed. It is even conceivable to vary the shape and / or orientation of the concave mirror 18 and / or of the deflection mirror 17 during the operation of the light module 1 so as to be able to adaptively change the design and the shape of the resulting side illumination during the operation of the illumination device. As a result, it would be possible, for example, to react to current traffic or ambient conditions and to illuminate the lateral edge regions of the resulting overall light distribution more or less strongly depending on the situation.
