1. A vehicle headlamp comprising:
a semiconductor light source; and a lens, having an optical axis along a forward direction, configured to forwardly radiate light from the semiconductor light source as a light distribution pattern having a cutoff line; wherein the lens is made of an incident surface in which the light from the semiconductor light source is incident into the lens and an emission surface from which the light that is incident into the lens is emitted, the incident surface of the lens is formed in a convex shape that is gently protruding to a side of the semiconductor light source, the incident surface being made of a free curved surface, the emission surface of the lens is formed in a convex shape that is gently protruding to an opposite side to the side of the semiconductor light source, the emission surface being made of a free curved surface, on the incident surface of the lens, a peak portion that forms a spot portion of the light distribution pattern is provided, the peak portion having a peak point in a given location that is on a left side or a right side with respect to the optical axis of the lens, wherein the incident surface of the lens is transversely nonsymmetrical to the optical axis of the lens, and wherein the emission surface of the lens is transversely symmetrical to the optical axis of the lens. |
