- the present invention relates to a vehicle headlight with a light source, a reflector emitted by the light source, one in front of the beam the lens arranged and a lens located between the reflector and the lens Aperture arrangement consisting of at least two optically small in relation to each other There are spaced panels, at least one of the panels being adjustable in height.
- Such a vehicle headlight has become known from DE 39 03 631 C1.
- This has a diaphragm arrangement in the beam path between a reflector and a lens on that from a fixed aperture with a top edge course for generation there is an asymmetrical low beam distribution pattern and also a height adjustable one Has aperture, the top edge of the aperture in the optically effective position Aperture shows a continuous, horizontal course.
- the adjustable aperture pivoted upwards into their optically effective position, so that the top edge of the fixed panel is covered by the height-adjustable panel. This will make the cut off asymmetrical portion in the light distribution of the fixed aperture, so when switching to left-hand traffic, dazzling oncoming traffic is avoided.
- each beam distribution pattern only the design of the top edge of the respective optically effective aperture, d. H. depends on the aperture that is pivoted into the beam path of the headlight.
- the first aperture expediently has an aperture edge course to generate a first low beam distribution pattern and the second diaphragm a diaphragm edge course for generating a second low beam distribution pattern on. It is particularly advantageous if the first aperture has an aperture edge course to generate a low beam distribution pattern for Left (right) traffic and the second aperture a diaphragm edge course for generation has a low beam distribution pattern for right (left) traffic to use to allow the headlamp according to the invention in most or all states.
- the invention can be implemented in a structurally simple manner if the diaphragms are around Axes are rotatably adjustable in height, with each panel having its own axis assigned to it having.
- the axes lie on both sides outside a vertical longitudinal median plane of the reflector.
