Abstract
A lens body includes: an incident surface where light entering within a predetermined angular range with respect to an optical axis of the light source is refracted in a condensing direction; a first reflection surface that internally reflects the light; and a second reflection surface that internally reflects part of the reflected light from the first reflection surface. The lens body includes an emission surface of a convex lens surface. The second reflection surface extends backward from near a focal point of the emission surface. Light obtained by blocking part of the light internally reflected by the first reflection surface with a front edge of the second reflection surface, and the light internally reflected by the second reflection surface are emitted from the emission surface to from a predetermined light distribution pattern including a cutoff line defined by the second reflection surface at the upper edge.
