Patent ID: 8186861

Claim:
A vehicular headlamp comprising: a projection lens disposed on an optical axis extending in a vehicular longitudinal direction; a light source disposed rearward of a rear side focal point of the projection lens; a reflector for reflecting light from the light source forward towards the optical axis; a movable shade constructed so that the movable shade partially blocks the reflected light from the reflector; and an actuator for moving the movable shade between: a light-shielding position where an upper end edge of the movable shade is positioned in a proximity of the optical axis near the rear side focal point of the projection lens, and a light-shielding moderating position where an amount of the reflected light from the reflector to be blocked is reduced as compared to the light-shielding position, wherein the light source is constructed as a line segment light source extending generally coaxially with the optical axis; wherein a pair of lower reflection areas are formed in a lower end portion of a reflective surface of the reflector so as to be positioned on both left and right sides of the optical axis, respectively; and wherein each of the pair of left and right lower reflection areas is formed so as to converge the light from the light source: at a position located forward of the rear side focal point of the projection lens in a horizontal direction, and on the same lateral side as that of the each lower reflection area with respect to the optical axis.
