In this invention, letters that can be seen by a pedestrian () are drawn on an intersection (). A mark (MM) that can be seen by the driver of the host vehicle (C) is drawn on the road () between the intersection () and the host-vehicle (C). The shapes of the letters (MO) are corrected in accordance with the positional relationship between the pedestrian () and the intersection (). The shape of the mark (MM) is corrected in accordance with the positional relationship between the driver of the host-vehicle (C) and the road ().

Road surface image-drawing system for vehicle

Provided is a vehicle headlamp which is capable of forming a light distribution pattern with a high degree of flexibility in shape. A vehicle headlamp includes an excitation light source, a phosphor, a scanning mechanism which includes a reflecting mirror configured to be swingable and which is configured to receive light emitted from the excitation light source on a reflecting surface of the reflecting mirror to scan light reflected on the reflecting surface toward the phosphor, a projection lens which is configured to transmit therethrough light emitted from the phosphor to form a light distribution pattern, and a condensing lens which is configured to condense the light emitted from the excitation light source onto the reflecting surface.

Vehicle headlamp

The light deflection device is configured to switch a first reflection position and a second reflection position in at least some region of the reflection part. The first reflection position is a position at which the light irradiated by the irradiation optical system is to be reflected toward the projection optical system so as to be effectively used as a part of a desired light distribution pattern. The second reflection position is a position at which the light irradiated by the irradiation optical system is to be reflected so as not to be effectively used. The detection unit is arranged at a position at which the light reflected at the second reflection position by the light deflection device can be detected.
