Spotlight/headlight, in particular headlight of a motor vehicle
A headlamp having a plurality of light sources which emit light during the operation of the headlamp, a primary optical unit, which at least partially shapes the light emanating from the light sources, a secondary optical unit, which includes a first optically functional boundary surface having at least one first section and at least one second section. A first portion of the light emanating from the primary optical unit passing through the at least one first section, and a second portion passing through the at least one second section. The at least one first section having a positive refractive power at least with respect to a first direction and the second section having a lower refractive power than the first section or as a lens having a negative refractive power at least with respect to the first direction.

at least two light sources that emit light during an operation of the headlamp;
a primary optical unit, which at least partially shapes the light emanating from the light sources;
a secondary optical unit, which includes a first optically functional boundary surface through which the light emanating from the primary optical unit passes, the first optically functional boundary surface having at least one first section and at least one second section, which are arranged such that a first portion of the light emanating from the primary optical unit passes through the at least one first section, and a second portion of the light emanating from the primary optical unit passes through the at last one second section,
wherein the at least one first section is a cylindrical lens having a positive refractive power at least with respect to a first direction, which corresponds to a horizontal direction in a state of the headlamp installed in the motor vehicle,
wherein the second section is a planar lens having a lower refractive power than the at least one first section, and
wherein the secondary optical unit has a second optically functional boundary surface that opposes the first optically functional boundary surface, the second optically functional boundary surface having a straight cylindrical lens extending along an entire length of the secondary optical unit.
2. The headlamp according to claim 1 , wherein the primary optical unit includes a plurality of light conductors, and wherein each of the at least two light sources are assigned to a respective one of the light conductors such that the light of the light source enters the light conductor and is shaped thereby.
3. The headlamp according to claim 2 , wherein at least a first one of the light conductors has different light shaping properties than at least a second one of the light conductors.
4. The headlamp according to claim 1 , wherein the first direction corresponds to a vertical direction in the state of the headlamp installed in the motor vehicle.
5. The headlamp according to claim 1 , wherein the at least one first section and the at least one second section are arranged next to each other.
6. The headlamp according to claim 1 , wherein a cylinder axis of the at least one first section of the first optically functional boundary surface is oriented substantially perpendicularly to a cylinder axis of the cylindrical lens of the second optically functional boundary surface.
7. The headlamp according to claim 1 , wherein a cylinder axis of the at least one first section of the first optically functional boundary surface is oriented vertically in the state installed in the motor vehicle and a cylinder axis of the cylindrical lens of the second optically functional boundary surface is oriented horizontally in the state installed in the motor vehicle.
8. The headlamp according to claim 1 , wherein the first optically functional boundary surface is an inlet surface, through which the light enters the secondary optical unit or a part of the secondary optical unit, and/or the second optically functional boundary surface is an outlet surface, through which the light emerges from the secondary optical unit or a part of the secondary optical unit.
9. The headlamp according to claim 1 , wherein the at least two light sources are light-emitting diodes or semiconductor lasers.
