A lamp unit includes a light-emitting element array composed by a plurality of light-emitting elements, having respective individual irradiation regions constituting a high-beam light-distribution pattern and configured to be capable of being turned on individually, mounted in array on a substrate, a projection lens disposed in front of the light-emitting element array, and a reflector disposed below the light-emitting element array. Inter-light-emitting-element spacing within the light-emitting element array widens the more separated the elements are from the projection lens optical axis.

Disclosed is an optical unit wherein a rotating reflector rotates about a rotation axis in one direction, while reflecting light emitted from a light source. The rotating reflector is provided with a reflecting surface such that the light reflected by the rotating reflector, while rotating, forms a desired light distribution pattern, said light having been emitted from the light source. The light source is composed of light emitting elements. The rotation axis is provided within a plane that includes an optical axis and the light source. The rotating reflector is provided with, on the periphery of the rotation axis, a blade that functions as the reflecting surface.

In this invention, letters that can be seen by a pedestrian (101) are drawn on an intersection (103). A mark (MM2) that can be seen by the driver of the host vehicle (C) is drawn on the road (104) between the intersection (103) and the host-vehicle (C). The shapes of the letters (MO4) are corrected in accordance with the positional relationship between the pedestrian (101) and the intersection (103). The shape of the mark (MM2) is corrected in accordance with the positional relationship between the driver of the host-vehicle (C) and the road (104).
