Lighting device for vehicle headlight

A lighting device for a vehicle headlight, the lighting device comprising:

• a first light module (105);
• a second light module (106);
• and
• a third light module (107),
• wherein:
• the first light module (105) is configured to generate a first overall light distribution (A) when installed in a vehicle in a region in front of the vehicle,
• the second light module (106) is configured to generate a first partial light distribution (F) when installed in the vehicle in the region in front of the vehicle, and
• the third light module (107) is configured to generate a second partial light distribution (Z) when installed in the vehicle in the region in front of the vehicle, and
• when the first and second light modules (105,106) are illuminated at the same time, the first overall light distribution (A) at least partially overlaps the first partial light distribution (F) such that a second overall light distribution (AF) is formed,
• the first overall light distribution is a low beam light distribution (A),
• the first partial light distribution is a partial high beam light distribution (F),
• the second overall light distribution is a high beam light distribution (AF), and
• the second partial light distribution (Z) lies entirely below an hh line (hh) or is bounded by at least one horizontal section of a light/dark boundary (10) of the low beam light distribution (A) at a top thereof and at least partially overlaps the high beam light distribution (AF), and the partial high beam light distribution (F) has a lower boundary (25), which lies at least partially in the low beam light distribution (A), and when the second and third light modules are illuminated at the same time, the partial high beam light distribution (F) is at least partially overlapped by the second partial light distribution (Z), wherein when the first, second, and third light modules (105,106,107) are illuminated at the same time, a third overall light distribution (AF′) is formed.
