  • Publication number: 20220221123
    Abstract: A vehicle light includes: a light source; a light condensing lens condensing a light emitted from the light source; and an irradiation pattern forming member having an irradiation slit for allowing the light to partially pass through, and that forms the passing light into an irradiation pattern. The irradiation slit has a farthest location that corresponds to a farthest portion projected at a farthest position in the irradiation pattern and a nearest location that corresponds to a nearest portion projected at a nearest position in the irradiation pattern. The light condensing lens, on the irradiation pattern forming member, makes the farthest location brightest and the nearest location darkest in an upper-lower direction, and diffuses the light emitted from the light source more in a width direction, which is orthogonal to an optical axis direction and to the upper-lower direction, than in the upper-lower direction.
