Abstract

A projection lens is disposed so that light emitted from a light source passes the projection lens. A shade is disposed in rear of the projection lens so as to block a part of the light emitted from the light source. The projection lens includes a first region and a second region. The first region has a first light scattering property. The second region has a second light scattering property lower than the first light scattering property. The shade and the projection lens are disposed so that a part of light projecting an edge of the shade as a peripheral edge of a light distribution pattern passes through the first region and another part of the light projecting the edge of the shade passes through the second region.
