  • Patent number: 11353186
    Abstract: A vehicular headlight includes: a first light emitting element (55) that emits a first light (L1); a second light emitting element (63) that emits a second light (L2); a shade (43); and a projection lens (20), in which an upper surface of the shade (43) has a first reflection surface (43a) that reflects another part of the first light (L1) to the projection lens (20) side, and a lower surface of the shade has a second reflection surface (43b) that reflects another part of the second light (L2) to the projection lens (20) side, and a front end (43c) of the shade (43) has a step (43cs) in an up and down direction corresponding to a shape of a cut line of a light distribution pattern of the low beam.

  • Patent number: 10895360
    Abstract: A vehicle lamp includes a projection lens and a plurality of light emitting elements arranged in parallel in a required direction behind the projection lens, and is configured to irradiate light emitted from each of the light emitting elements toward a front side through the projection lens. A plurality of diffusing lens elements that diffuse the light emitted from each of the light emitting elements in the required direction are provided on a front surface and/or a rear surface of the projection lens in a stripe shape to extend in a direction orthogonal to the required direction when viewed from the front side of the lamp.
