摘要:
A direct projection type vehicular headlamp includes a projection lens having an incident surface and a light emission surface, and a semiconductor light source. A reference surface and a light control surface positioned below the reference surface are provided on the incident surface, and the light control surface is inclined forward with respect to the reference surface in a direction form an upper side to a lower side. The reference surface has a shape to emit from the light emission surface direct light from the semiconductor light source, which has passed through the reference surface and the light emission surface, as substantially parallel light, and the light control surface has a shape to project the direct light from the semiconductor light source, which has passed through the light control surface and the light emission surface, on an upper portion of a predetermined distribution pattern formed by the substantially parallel light.
