Abstract
A motor vehicle includes an environment illuminating device for emitting light toward the ground in the environment of the motor vehicle. The environment illuminating device includes one or more luminous modules, each of which is configured to generate a light distribution on the ground. A respective luminous module includes an image generator configured to generate light radiation from light from an illuminant, the light radiation containing two-dimensional image information concerning, firstly, a symbol representation and, secondly, a light pattern and/or a homogeneous area with a substantially constant luminance. Furthermore, the respective luminous module includes an optical device, on which the light radiation from the image generator is incident.
Claims16
A motor vehicle comprising:
- an environment illuminating device for emitting light toward ground in an environment of the motor vehicle, wherein:
- the environment illuminating device comprises one or more light modules, which are each configured to generate a light distribution on the ground;
- a respective light module comprises an imager, which is configured to generate a light radiation from light of a lighting device, which contains an item of two-dimensional image information for a symbol, and a light pattern and/or a homogeneous surface having essentially constant luminance;
- the respective light module further comprises an optical device, on which the light radiation of the imager is incident;
- the optical device is configured to divide the light radiation of the imager so that a first partial radiation and a second partial radiation result, wherein the first partial radiation and the second partial radiation are disjoint from one another;
- the optical device is further configured to generate a first illumination region comprising the symbol in the light distribution on the ground from the first partial radiation and to generate a second illumination region comprising at least one of the light pattern or the homogeneous surface in the light distribution on the ground from the second partial radiation, and
- the optical device comprises a first projection optical unit on which only the first partial radiation is incident, to generate the first illumination region by way of a projection on the ground.
