Abstract

The present invention provides a vehicular lamp and a vehicle having the vehicular lamp, which can equalize the clarity of a light distribution pattern drawn on a road near the vehicle and a light distribution pattern drawn on a road far from the vehicle. A vehicle lamp (1) has: road surface drawing light sources (12a to 12d) that emit light that becomes a light source image; and a projection lens (20) that has an optical axis (Ax) extending in the The light emitted from the light sources (12a-12d) is transmitted. Using the light (La~Ld) emitted from the light sources (12a~12d) and passing through the projection lens (20), a plurality of light distribution patterns (Pa~Pd) can be formed on the road surface from the vicinity of the lamp to the distance of the lamp. In a state where the relative positions of the lens (20) and the light source image are different, each light distribution pattern (Pa to Pd) is projected onto the road surface.

Description

technical field [0001] The present invention relates to a vehicle lamp and a vehicle having the vehicle lamp. Background technique [0002] Patent Document 1 discloses a lamp unit including a light source, a rotating shade, a reflector, and a projection lens in a housing. The rotatable shade is rotatable by driving a motor or the like, and by moving a shade plate or a cutout for forming a desired light distribution pattern on the optical axis, at least part of the light irradiated from the light source is shielded to form a low beam. Use a light distribution pattern or a high beam light distribution pattern. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2012-006482 [0004] The rotary visor disclosed in Patent Document 1 is used to form a light distribution pattern for low beam or a light distribution pattern for high beam as described above, and it is difficult to form a light distribution pattern with a relatively narrow irradiation range for roa...
