Ground projection device for motor vehicle

Abstract

The invention relates to a ground projection device for a motor vehicle for generating at least one ground projection, wherein the ground projection device comprises an illuminant and a projection means, wherein the illuminant is configured to generate light and radiate the latter, at least in part, on the projection means, wherein the projection means is configured to project the light, radiated on the projection means by the illuminant, onto a roadway as a ground projection to the side of the motor vehicle when the ground projection device is installed in the motor vehicle, wherein the ground projection comprises at least two spaced apart light segments, wherein the illuminant, to this end, comprises at least two individually controllable light sources, wherein at least one light source is assigned to each light segment, wherein the projection means has a focus or focal line, wherein at least one of the at least two light sources is arranged offset relative to the focus or the focal line of the projection means, wherein a first portion of the light is radiated along a first beam direction, which is directed directly at the projection means, wherein a second portion of the light is directed in a second beam direction, which is not directed directly at the projection means, wherein the ground projection device comprises absorption means and / or deflection means, which are configured to absorb and / or deflect the second portion of the light at least in part so that the second portion of the light does not strike the projection means.

Description

technical field [0001] The invention relates to a floor projection device for a motor vehicle for generating at least one floor projection, wherein the floor projection device has a lighting device and a projection device, preferably at least one projection lens, wherein the lighting device is designed for Generating light and projecting the light at least partially onto a projection device, wherein the projection device is designed to project the light emitted by the lighting device onto the projection device on the side of the motor vehicle with the floor projection device installed in the motor vehicle onto a road On the road as a floor projection, wherein the floor projection comprises at least two light segments spaced apart from one another, wherein the lighting means has at least two individually controllable light sources for this purpose, wherein each light segment is associated with at least one light source, wherein the projection means having a focal point or focal...

Problems solved by technology

However, devices capable of emitting a plurality of light segments onto the roadway have the disadvantage that if the individual light segments are emitted onto the roadway, they would have insufficient contrast due to the scattered light of the light source, which leads to a poorer signal effect
