1. A vehicle headlight comprising:
a reflector having a spheroidal reflecting surface with a first focus and a second focus; a rotationally asymmetric projection lens having a light emitting surface on a front side and a light incident surface on a rear side and a focus close to the light incident surface, the projection lens being disposed in front of the reflector with the focus disposed substantially at the second focus; and a light source disposed substantially at the first focus, the light source configured to emit light that is reflected by the reflecting surface, incident on the light incident surface to enter the projection lens, and projected through the light emitting surface of the projection lens, wherein the projection lens has an optical axis passing through the focus of the projection lens and extending in a front-to-rear direction of the vehicle headlight, and the light emitting surface of the projection lens is a surface inclined with respect to the optical axis of the projection lens, the light incident surface is a surface in which, when a plurality of light beams in parallel to the optical axis of the projection lens are incident on the light emitting surface to enter thereinside, the plurality of light beams exiting through the light incident surface are focused at the focus of the projection lens, the reflecting surface has an optical axis passing through the first focus and the second focus and is disposed such that the optical axis of the reflecting surface is inclined with respect to the optical axis of the projection lens by a predetermined angle so that light emitted from the light source and projected forward through the light emitting surface of the projection lens is made uniform with respect to the optical axis of the projection lens. |
