Adb function adjustment method and vehicle light with adb function

An ADB function adjustment method for a vehicle light, characterized in that:

• a superposed illumination light shape is formed by a periodic high-speed change of a light shape, and the periodic high-speed change of the light shape is a shape change, that is, dynamic superposition of light shapes, or a position change or a synchronous change in shape and position;
• a light source is quickly switched off in conjunction with the periodic change of the light shape to generate one or more local dark areas, thereby realizing an ADB function;
• Lambertian-like divergent light rays emitted by the LED light source are collimated by an optical lens and are then irradiated to form illumination light rays nearly in parallel, the illumination light rays form a primary light spot and a primary light shape thereof on a front vertical screen, and the primary light shape is a primary intensive light spot formed around the primary light spot;
• the light source is transversely displaced with respect to the lens to form a secondary spot light and a continuous secondary light shape thereof;
• a high-beam illumination light shape is formed by dynamic superposition of the primary light shape and the secondary light shape, wherein the dynamic superposition of the primary light shape and the secondary light shape includes superposition of shape changes or position changes of the light shapes;
• the light source quickly and linearly reciprocates in a transverse area to form a continuous illumination light shape.
