20220099262 · 2022-03-31 ·

An illumination apparatus for a motor vehicle includes a light source for emitting light of a first mixed color, said light source containing one or more laser diodes for generating monochromatic light and a first conversion element for converting the monochromatic light into the light of the first mixed color. The illumination apparatus also includes a first optical device which images the light source as a real image in an intermediate image plane, and a second optical device which generates a predefined light distribution from the real image in the intermediate image plane. A second conversion element is provided at the site of the real image in the intermediate image plane in order to convert the light of the first mixed color into light of a second mixed color.

Optical unit and method for determining reflection plane

An optical unit includes: a light source; a rotating reflector configured to be rotated in a single direction with the rotational axis as the center of rotation while reflecting light emitted from the light source; and a projector lens configured to project light reflected by the rotating reflector in the light irradiation direction. The projector lens has a first lens region LR1 that defines the first focal plane and a second lens region that defines the second focal plane that differs from the first focal plane. The light source is arranged such that, when the rotating reflector is set to the first rotational position, its virtual position is in the vicinity of the focal plane, and such that, when the rotating reflector is set to the second rotational position, its virtual position is in the vicinity of the focal plane.
