<p>A vehicle headlight (10) utilizes a rotationally asymmetric projection lens (14) with its light emitting surface (20) inclined with respect to the optical axis (AX 1 ) thereof, whereby the light emitted from the light source (16) and projected forward through the light emitting surface (20) of the projection lens (14) can be diffused substantially uniformly with respect to the optical axis (AX 1 ) of the projection lens (14), for example, uniform substantially in the right and left directions and/or the upper and lower directions. This can be achieved by designing the reflecting surface (12a) to have its optical axis (AX 2 ) that is inclined with respect to the optical axis (AX 1 ) of the projection lens (14) by a predetermined angle so that the light emitted from the light source (16) and projected forward through the light emitting surface (20) of the projection lens (14) is made uniform with respect to the optical axis (AX 1 ) of the projection lens (14) (for example, uniform substantially in the right and left directions and/or the upper and lower directions).</p> |
