    摘要： The present invention relates to a vehicle headlight that ensures maintaining usage efficiency of a light of the vehicle headlight while improving visibility of an irradiation target on a road by a headlight light from a host vehicle. A vehicle headlight 1 having a headlight unit 4 forming a light distribution pattern by projecting a light B1 from a light source 9 ahead includes a polarized light generator 8, a first headlight unit 5, and a second type headlight unit 6. The polarized light generator 8 generates a first and a second polarized lights (B11, B12) by the light B1 from the light source 9. The first headlight unit 5 indicates main light distribution patterns (La1, Lb1) by a first polarized light B11 ahead. The second type headlight unit 6 scans with a second polarized light B12 using a scanning mechanism 13, and indicates ahead auxiliary light distribution patterns (La2, Lb2) irradiating a range narrower than the main light distribution patterns (La1, Lb1).

    摘要： A vehicular lamp includes a plurality of light-emitting elements arranged such that light-emitting surfaces of the light-emitting elements face toward a front of the vehicular lamp; and a projection lens having a plurality of projection regions that face the respective light-emitting elements, and project light source images of the respective light-emitting elements facing the projection regions, to the front of the vehicular lamp. A lamp rear surface of the projection lens has protruding portions provided in the respective projection regions, the protruding portions protruding toward the respective light-emitting elements facing the protruding portions. A lamp front surface of the projection lens is flatter than the lamp rear surface.

    摘要： Provided is a vehicular headlamp which is capable of enhancing visibility while suppressing glare by forming a dark portion in a portion of a light distribution pattern and suppressing the vicinity of the formed dark portion from becoming a blue series color. The vehicular headlamp includes a light-emitting element, a projection lens, a reflector, a beam shaper, a first shaper disposed between the light-emitting element and a cut-off line forming portion and configured to shield a part of the light reflected from the reflector to form a dark portion in a portion of a low beam light distribution pattern, and a second shaper portion disposed between the cut-off line forming portion and the projection lens and configured to shield a part of the light incident to the lower side of an optical axis of the projection lens.
