Title:
VEHICLE LAMP
Document Type and Number:
WIPO Patent Application WO/2023/176671
Kind Code:
A1
Abstract:
Provided is a vehicle lamp which can inhibit the generation of light distribution unevenness in a light distribution pattern for low beams, and for which a partial light distribution pattern for high beams does not spread horizontally. The present invention comprises: a projection lens (60); an upper separator (51) disposed behind the projection lens and above an optical axis (AX60) of the projection lens; a lower separator (52) disposed behind the projection lens and below the optical axis of the projection lens; a low beam light source (31A); and a high beam light source (31B). The upper separator includes a low beam light-incidence section and a low beam light-emitting surface, the lower separator includes a high beam light-incidence section and a high beam light-emitting surface, and the focal point of the projection lens is positioned between the low beam light-emitting surface and the high beam light-emitting surface. The optical length of the upper separator is longer than the optical length of the lower separator.
