摘要： 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.

摘要： 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.

摘要： 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.
