A headlamp includes a first semiconductor chip and a second semiconductor chip for generating light. The first and second semiconductor chips each include several pixels. A first optics is arranged to direct light from the first semiconductor chip with a first magnification into a base region. Via a second optics, light of the second semiconductor chip is directed into a bright region with a second magnification. The second magnification is between 0.3 times and 0.7 times the first magnification inclusive, so that the bright region is smaller than the base region. The bright region is within the base region.
