VEHICULAR HEADLAMP

摘要

A vehicular headlamp has a projection lens having an optical axis extending in a front-back direction, a light source disposed behind a rear side focal point of the projection lens, a reflector that reflects direct light from the light source toward the projection lens, a shade disposed between the projection lens and the light source, and that partially blocks light reflected from the reflector and to form a cut-off line of a light distribution pattern, a first reflective surface disposed in front of the reflector, that partially reflects direct light from the light source downward to the a front of the shade, and a second reflective surface disposed in front of the shade and lower than the rear side focal point of the projection lens, that reflects the light reflected from the first reflective surface toward the projection lens.

1. A vehicular headlamp comprising:
a projection lens having an optical axis extending in a front-back direction; a light source disposed behind a rear side focal point of the projection lens; a reflector that reflects direct light from the light source toward the projection lens; a shade disposed between the projection lens and the light source, that partially blocks light reflected from the reflector and to form a cut-off line of a light distribution pattern; a first reflective surface disposed in front of the reflector, that partially reflects direct light from the light source downward to a front of the shade; and a second reflective surface disposed in front of the shade and lower than the rear side focal point of the projection lens, that reflects the light reflected from the first reflective surface toward the projection lens, wherein the first reflective surface has a front side first reflective surface, and a rear side first reflective surface disposed behind the front side first reflective surface, and wherein the reflected light which is incident on the second reflective surface from the front side first reflective surface and reflected by the second reflective surface is caused to irradiate in front of a lamp so as to illuminate above the reflected light which is incident on the second reflective surface from the rear side first reflective surface and reflected by the second reflective surface.
