A vehicular headlight includes: a first light emitting element () that emits a first light (L); a second light emitting element () that emits a second light (L); a shade (); and a projection lens (), in which an upper surface of the shade () has a first reflection surface () that reflects another part of the first light (L) to the projection lens () side, and a lower surface of the shade has a second reflection surface () that reflects another part of the second light (L) to the projection lens () side, and a front end () of the shade () has a step () in an up and down direction corresponding to a shape of a cut line of a light distribution pattern of the low beam.

Vehicular headlight

A vehicular lamp includes a first light source that emits light for forming a first distribution pattern, a second light source that emits light for forming a second distribution pattern that is added to the first distribution pattern, and a light guide member disposed in front of the first light source. The light guide member includes a first incidence surface on which the light emitted from the first light source is incident, a total reflection surface by which a part of the light incident from the first incidence surface is totally reflected, and a first emission surface from which the light totally reflected by the total reflection surface is emitted toward the lamp front. A part of the light emitted from the second light source passes through the total reflection surface and the light guide member and is emitted from the first emission surface toward the lamp front.

Vehicular lamp

A vehicle lamp includes a projection lens, a first light source disposed behind the projection lens and configured to emit light forming a low-beam light distribution pattern which is a predetermined light distribution pattern, a reflector configured to reflect light emitted from the first light source toward a first rear focal point of the projection lens, and a second array light source disposed behind the projection lens and having a plurality of semiconductor light emitting elements arranged in at least one row. The second array light source is configured to emit light forming an additional light distribution pattern, and the center position or maximum light intensity position of the additional light distribution pattern overlaps with the low-beam light distribution pattern on a virtual vertical screen in front of the lamp.

Vehicle lamp

Provided is a vehicular headlamp including: a first light source that emits a first light serving as a low beam; a second light source that emits a second light serving as a high beam; a projection lens that transmits the first light and the second light; a third light source that emits a third light in response to at least one of an operation of a steering and an operation of a direction indicator; and an optical member that adjusts a light distribution of the third light. The first light source, the second light source, and the third light source share a single heat sink.

Vehicular headlamp

There is provided a vehicle lamp including a projection lens, a first light source arranged at a rear of the projection lens and configured to emit light for forming a predetermined light distribution pattern, a reflector configured to reflect the light emitted from the first light source towards the projection lens, a first array light source arranged at the rear of the projection lens and including a plurality of semiconductor light emitting elements aligned in at least one row, and a second array light source arranged at the rear of the projection lens and including a plurality of semiconductor light emitting elements aligned in at least one row. The first array light source and the second array light source are arranged in an upper-lower direction.

A lamp includes a plurality of light sources arranged in parallel, a projection lens through which light emitted from the plurality of light sources is transmitted, and a first inter-light source reflector and a second inter-light source reflector which are disposed so as to sandwich a line connecting the light sources adjacent to each other and which are configured to reflect a part of the light emitted from the light sources toward the projection lens.
