Problems solved by technology

However, the disadvantage is that the light image is very limited with regard to its geometry, that is to say with respect to the ratio of width to height in the projection ahead of the vehicle, but also with regard to the brightness to be achieved and therefore the The DLP® technology described is not ideal for all light functions, e.g. in cornering light functions

Embodiment Construction

[0109] Now, refer to Figure 1 to Figure 12 Examples of the present invention are explained in more detail. In particular, the relevant components in the headlight are shown for the present invention, wherein it is clear that the headlight also contains many other, not shown components, which are implemented in a motor vehicle, such as in particular a PKW or a motorcycle. meaningful use in . For the sake of clarity, cooling devices for structural components, control electronics, further optical elements, mechanical adjustment mechanisms or holders, for example, are therefore not shown.

Abstract

The invention relates to a vehicle headlight comprising at least two light modules, wherein a first light module is designed to generate a dynamically controllable first partial light distribution (510). The first light module comprises at least one first light source and at least one first device and at least one first projection optical mechanism for generating a first luminous image originating from the first sub-light distribution (510), wherein, The first luminous image can be projected as a first light image onto the road in a first radiation direction by means of the at least one first projection optics. The second light module is configured to generate a dynamically controllable second sub-light distribution (520). The second light module comprises at least one second light source and at least one second device and at least one second projection optics for generating a second luminous image originating from the second sub-light distribution (520).

Description

technical field [0001] The invention relates to a vehicle headlight comprising at least two light modules. Background technique [0002] In the development of current headlight systems, the desire to be able to project onto the roadway a light image with the highest possible resolution, which can change rapidly and which is compatible with the corresponding traffic, road and light, is increasingly at the center of attention. conditions match. The term "roadway" is used here for simplified presentation, since whether the light image actually lies on the roadway or extends beyond it obviously depends on the local facts. In principle, the light image in the sense used here is defined by its projection onto a vertical plane which corresponds to the relevant standards concerning lighting technology for motor vehicles. The resulting light image should also be adaptable to different traffic situations. [0003] In order to respond to this mentioned requirement, in particular hea...
