  • Patent number: 11415290
    Abstract: A vehicle lamp includes a mirror, a plurality of light-emitting elements, and a lens. The mirror is capable of rotating a mirror surface around a rotary axis in a vertical direction. The mirror surface extends along the rotary axis. The light-emitting elements are arranged on a lateral side more than the mirror in a vehicle width direction. The lens irradiates a range wider than the mirror with light from the light-emitting elements. The light-emitting elements are disposed apart from each other such that light distribution images of the light reflected by the mirror surface are aligned along the vehicle width direction. The mirror rotates to combine the adjacent light distribution images and form a main light distribution pattern.
