VEHICLE HEADLAMP OPTICAL SYSTEM, VEHICLE HEADLAMP, AND VEHICLE

A vehicle headlamp optical system, a vehicle headlamp, and a vehicle. The vehicle headlamp optical system comprises a plurality of modules and a light distribution lens (4) that is disposed in front of each module. The plurality of modules comprise at least one high-beam module (1), at least one main low-beam module (3), and at least one auxiliary low-beam module (2). The light distribution lenses (4) are narrow, long light distribution lenses. Each module is disposed at an interval along the length direction of the light distribution lenses (4). Thus, the miniaturization and diversified design of a vehicle headlamp can be achieved.
