A device for deflecting light beams is provided, which includes a swing-mounted light exit segment of an optical waveguide and a swing-mounted mirror. The device features a first rotation device that is set up to rotate the light exit segment of the optical waveguide, from which light is able to strike the mirror, in a rotational plane, and a second rotation device that is set up to rotate the mirror around a rotational axis situated in the mirror plane, which deviates from the vertical to the rotational plane.
