Abstract

The present disclosure provides an automobile lamp lighting system, including a light source, a reflecting mirror, a light-shielding plate, and a lens. The lens includes a reflecting surface and a refracting surface opposite to the reflecting surface. When an external parallel light is incident into the lens, the external parallel light sequentially passes through the refracting surface for a first refraction, is reflected by the reflecting surface, passes through the refracting surface for a second refraction, exits the lens, and is converged to form a focal point. The reflecting mirror includes a near focal point and a far focal point, the light source is arranged at the near focal point, and the far focal point is located near the focal point of the lens. The light-shielding plate includes a light-shielding plate cut-off line located at the focal point of the lens.
