Headlight for vehicles
A headlight for vehicles including at least one light source and an illumination optics system associated therewith, comprising a micromirror array and a projection optics system. A central processing unit comprising a light source control unit and an array control unit is associated with the light source and the micromirror array. The shaped rays of light of the light source are directed at the micromirror array, and the reflected light beam structured thereby is projected by the projection optics system as a light image into a traffic space. At least two light sources are provided, the rays of light of which are directed at a micromirror array common to the light sources, and at least two superimposed regions of a projection optics system having different refractive powers for at least two image regions of the light image are associated with the light beam reflected by the micromirror array.

at least two light sources ( 1 A, 1 B; 1 B- 1 , 1 B- 2 , 1 B- 3 ); and
an illumination optics system associated with one of the at least two light sources, the illumination optics system comprising a micromirror array ( 7 ) and a projection optics system ( 9 , 9 f ) comprising a lens, a central processing unit ( 4 ) comprising a light source control unit ( 3 ) and an array control unit ( 12 ) associated with the at least two light sources and the micromirror array,
wherein the illumination optics system is configured to direct shaped rays of light ( 2 A, 2 B) of one of the at least two light sources at the micromirror array, and wherein a reflected light beam is projected by the projection optics system as a light image ( 10 ) into a traffic space,
wherein rays of light from the at least two light sources are directed at the micromirror array ( 7 ) that is common to the at least two light sources, and wherein at least two superimposed regions ( 9 k A, 9 k B) of the projection optics system ( 9 , 9 f ), which have different refractive powers for at least two image regions of the light image are associated with the reflected light beam, and
wherein the rays of light of the at least two light sources ( 1 A, 1 B; 1 B- 1 , 1 B- 2 , 1 B- 3 ) are directed at the micromirror array ( 7 ) at varying angles of incidence.
2. The headlight according to claim 1 , wherein an active mirror surface ( 7 f ) of the micromirror array ( 7 ) is divided into sub-regions, which are associated with individual light sources of the at least two light sources.
3. The headlight according to claim 1 , wherein one light source ( 1 A, 1 B) of the at least two light sources is associated with the illumination optics system ( 6 A, 6 B) located between the at least two light sources and the micromirror array ( 7 ).
4. The headlight according to claim 1 , wherein two or more light source ( 1 B- 1 , 1 B- 2 , 1 B- 3 ) of the at least two light sources are associated with the illumination optics system ( 6 B) located between the at least two light sources and the micromirror array ( 7 ).
5. The headlight according to claim 1 , wherein the at least two superimposed regions ( 9 k A, 9 k B) of the projection optics system ( 9 ) are superimposed and designed in a lens-like manner from a lens body ( 9 k ) made of optical glass/plastic material.
6. The headlight according claim 5 , wherein the lens body ( 9 k ) is located in a front region of the headlight, and a sub-optics system ( 9 f ) comprising a lens is arranged between the micromirror array ( 7 ) and the lens body.
7. The headlight according to claim 1 , wherein one region ( 9 k A) of the projection optics system ( 9 ) is associated with one ( 1 A) of the at least two light sources, while another region ( 9 k B) of the projection optics system is associated with two or more light sources ( 1 B- 1 , 1 B- 2 , 1 B- 3 ) of the at least two light sources.
