摘要： A headlight includes a first LED cluster having a plurality of first LEDs arranged next to one another on a common first substrate, a second LED cluster having a plurality of second LEDs arranged next to one another on a common second substrate, and an output coupling optical unit having a plurality of optical elements, of which an optical element which comes first in a beam path of the LED clusters has, a light incidence surface which is common to the LED clusters. The LED clusters have a lateral distance from one another which is at least as great as an extent of the LED clusters in the same direction. The common light incidence surface has a locally delimited light incidence region directly in front of an associated LED cluster. The locally delimited light incidence region deviates from the basic shape of the light incidence surface.
