Abstract:
A vehicle headlamp of the present invention is provided with: a semiconductor-type light source; a main reflecting surface; a first auxiliary reflecting surface; a shade; a second auxiliary reflecting surface; a third auxiliary reflecting surface; and a fourth auxiliary reflecting surface. The shade forms a light distribution pattern for passing, having cutoff lines. The first auxiliary reflecting surface and the second auxiliary surface form a light distribution pattern for overhead sign. The first auxiliary reflecting surface, the third auxiliary reflecting surface, and the fourth auxiliary reflecting surface form an auxiliary light distribution pattern between the light distribution pattern for passing, having the cutoff lines, and a light distribution pattern for overhead sign. As a result, the vehicle headlamp of the present invention improves visibility.
