发明名称 VEHICULAR HEADLAMP
摘要 A vehicular headlamp has a projection lens, a first light source disposed rearward of a rear focal point of the projection lens, a first reflector that reflects emitted light from the first light source above the first light source and toward the projection lens, a shield disposed such that a front end edge of the shield passes through a vicinity of the rear focal point to block a portion of reflected light from the first reflector, a second reflector that is disposed forward of the first reflector, and that reflects the emitted light from the first light source toward a position between the first light source and the shield, and a third reflector that is disposed between the first light source and the shield, and that reflects reflected light from the second reflector toward the projection lens by passing the reflected light below the shield.
