Title:
VEHICULAR HEADLIGHT
Document Type and Number:
WIPO Patent Application WO/2019/177050
Kind Code:
A1
Abstract:
The present invention comprises: a first light emitting element (55) that emits first light (L1) that serves as a low beam, a normal line to a surface that emits the first light (L1) being oriented forward with a downward incline; a second light emitting element (63) that is disposed below the first light emitting element (55) and emits second light (L2), a normal line to a surface that emits the second light (L2) being oriented forward with an upward incline; a shade (43) that extends forward from between the first light emitting element (55) and the second light emitting element (63); and a projector lens (20), disposed further forward than the shade (43) and directly transmitting a portion of the first light (L1) and a portion of the second light (L2). The shade (43) comprises, on an upper surface, a first reflecting surface (43a) that reflects another portion of the first light (L1) toward the projector lens (20) and, on a lower surface, a second reflecting surface (43b) that reflects another portion of the second light (L2) toward the projector lens (20). A front end (43c) of the shade (43) has a level difference (43cs) in the vertical direction that corresponds to the shape of a cutline of a light distribution pattern of the low beam.
