Projection headlight arrangement for vehicles

A projection headlight arrangement for vehicles with a left projection headlight and a right projection headlight, each comprising:

• a reflector exhibiting two focal points,
• a light source arranged in a first focal point of the reflector,
• a lens upstream of the reflector in the direction of light emission and
• a diaphragm shaft arranged between the lens and the reflector, which is displaceable in several rotary positions around a horizontal rotary axis running transverse to the optical axis, wherein the rotary positions each have a diaphragm edge of the diaphragm shaft assigned for the creation of a light-dark boundary for a specified light distribution,
• a sensor unit is provided for the detection of a traffic participant located in the far-field of the vehicle,
• a control unit said control unit moving the diaphragm shaft in dependence on a sensor signal of the sensor unit that such a diaphragm edge of the diaphragm shaft provides a complete illumination of a far-field;
• the diaphragm edges are assigned to light function sectors of the diaphragm shaft, said light function sectors sweeping a variable angular region in the direction of rotation of the diaphragm shaft;
• a first light function sector is constructed as an adaptive passing light function sector which extends over an acute or right angle around the rotary axis of the diaphragm shaft and which exhibits a plurality of diaphragm edges, each of said diaphragm edges producing a passing light distribution, each of said passing light distributions being one of a town light distribution or a country road light distribution or a freeway light distribution or an overpass light distribution or a passing light distribution for right-handed traffic or a passing light distribution for left-handed traffic.
