Headlights for motor vehicles
A headlight for vehicles, having a plurality of light sources ( 5,13 ) and an optics ( 11 ) assigned to the light sources, in which a first lighting unit ( 1 ) having at least one light source ( 13 ) for generating a first, dynamically variable light effect and a second, laser lighting unit ( 4 ) having at least one laser light source ( 5 ), at least one beam defection unit ( 7 ) and at least one light conversion unit ( 8 ) are provided, and the optics ( 11 ) is configured to combine the two light effects generated by the first lighting unit and at the light conversion unit of the second laser lighting unit to form an overall light distribution on a carriageway.
1. A headlight for vehicles comprising:
at least one optics ( 3 , 9 ; 11 );
a first lighting unit ( 1 ) comprising a plurality of individual light sources ( 13 ), which are arranged in at least two rows and a plurality of columns;
a second laser lighting unit ( 4 ) comprising at least one laser light source ( 5 );
at least one beam deflection unit ( 7 ); and
at least one light conversion unit ( 8 ),
wherein the at least one optics ( 3 , 9 ; 11 ) is configured to combine two light effects generated by the first lighting unit and the at least one light conversion unit of the second laser lighting unit to form an overall light distribution on a carriageway,
wherein the at least one beam deflection unit ( 7 ) is formed as micromirrors pivotable about at least one axis, and
wherein the plurality of individual light sources ( 13 ) are configured to be controlled to generate a dynamically variable light distribution on the carriageway.
2. The headlight of claim 1 , wherein individual optics ( 10 ; 15 ) are assigned to each of the plurality of individual light sources.
3. The headlight of claim 1 , wherein the at least one optics comprises a first optics unit assigned to the first lighting unit and a second optics unit assigned to the second laser lighting unit.
4. The headlight of claim 1 , wherein the at least one optics comprises a single common optics unit ( 11 ), which is assigned to both the first lighting unit and the second laser lighting unit.
5. The headlight of claim 1 , wherein the at least one optics ( 3 , 9 ; 11 ) is formed as a lens.
6. The headlight of claim 1 , wherein the at least one laser light source ( 5 ), the at least one beam deflection unit ( 7 ), and the at least one light conversion unit ( 8 ) of the second laser lighting unit ( 4 ) are combined in a structural unit.
7. The headlight of claim 1 , wherein the at least one light conversion unit ( 8 ) of the second laser lighting unit ( 4 ) is provided on the first lighting unit ( 1 ) in a region of a light exit surface ( 16 ) thereof.
8. The headlight of claim 1 , wherein the at least one beam deflection unit ( 7 ) is configured to generate a dynamically variable light effect at the at least one light conversion unit ( 8 ), comprises segments that are configured to be selectively illuminated.
9. The headlight of claim 1 , wherein the plurality of individual light sources ( 13 ) of the first lighting unit ( 1 ) are LEDs.
