Automobile lamp lighting system, automobile lamp assembly and automobile

An automobile lamp assembly, comprising an automobile lamp lighting system, the automobile lamp lighting system comprises a light source (1), a reflecting mirror (2, 2a, 2b), a light-shielding plate (3), and a lens (4);

• wherein
• the lens (4) comprises a reflecting surface (4a) and a refracting surface (4b) opposite to the reflecting surface (4a);
• when an external parallel light is incident into the lens (4), the external parallel light sequentially passes through the refracting surface (4b) for a first refraction, is reflected by the reflecting surface (4a), and passes through the refracting surface (4b) for a second refraction, then the external parallel light exits the lens (4) and is converged to form a focal point (4c);
• the reflecting mirror (2, 2a, 2b) includes a near focal point and a far focal point, the light source (1) is arranged at the near focal point of the reflecting mirror (2, 2a, 2b), and the far focal point of the reflecting mirror (2, 2a, 2b) is located near the focal point (4c) of the lens (4);
• and
• the light-shielding plate (3) includes a light-shielding plate cut-off line with a same shape as a cut-off line of light and darkness (a) of a low beam light pattern of the automobile lamp, and the light-shielding plate cut-off line is located at the focal point (4c) of the lens (4).
