Abstract:
1. A vehicle headlight comprising: a semiconductor light source including a base board, a plurality of semiconductor light-emitting chips, and an encapsulating resin, the plurality of semiconductor light-emitting chips located adjacent the base board and arranged in a matrix so that the plurality of semiconductor light-emitting chips emits a matrix light including a central column light portion and both edge column light portions, wherein the encapsulating resin encapsulates each of the semiconductor light-emitting chips; an imaging lens having an incoming surface and an outgoing surface, and the incoming surface of the imaging lens is located adjacent the semiconductor light source so that the imaging lens enlarges each elemental portion of light of the matrix light including the central column light portion and both edge column light portions emitted from the semiconductor light source; and a reflector including a plurality of reflex surfaces, the plurality of reflex surfaces located adjacent the outgoing surface of the imaging lens and arranged in a matrix so as to receive each elemental portion of light of the matrix light enlarged by the imaging lens from the outgoing surface of the imaging lens, each of the reflex surfaces having a vertical curvature and a horizontal curvature, and wherein each of the vertical curvatures of the reflex surfaces arranged in rows is substantially the same with respect to each other, each of the horizontal curvatures of the reflex surfaces arranged in columns is configured such that a corresponding column light portion of the matrix light is horizontally extended gradually in a wider range as the corresponding column light approaches from the central column light portion toward both edge column light portions.
