Abstract:
A headlamp, and in particular a headlamp for a motor vehicle, comprising a digital micromirror device which reflects light hitting it so that it exits at least partially from the headlamp when the headlamp is operated. The headlamp also includes at least one first light source which emits light with a first luminance, and which hits the digital micromirror device at least partially when the headlamp is operated. The headlamp also includes at least one second light source emitting light when the headlamp is operated, and having a second luminance which is different from the first luminance. The light emitted from the at least one second light source hits, at least partially, the digital micromirror device. The areas of incidence of the light emitted by the light sources on the digital micromirror device overlap at least partially. On the digital micromirror device, the range of incidence of the light emitted by the at least one first light source differs from the range of incidence of the light emitted by the at least one second light source.
