WIPO Patent Application WO/2019/087727
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a vehicle lamp in which an exit surface of a lens has a reduced distortion in planar shape, and with which a stripe due to brightness difference is not prone to occur. The vehicle lamp is provided with: a first light source (L) which emits light for a low-beam light distribution; a lens (70) disposed on the front side of the first light source (L); a shade (40) which is disposed between the first light source (L) and the lens (70), and which forms a cut-off line (CL) of the low-beam light distribution pattern (LP); a reflector (30) which reflects the light from the first light source (L) toward the lens (70); and a second light source (H) which is disposed between the first light source (L) and the lens (70), and which emits light for a high-beam added light distribution (HAP). A rearward focal point (P) of the lens (70) is positioned on the front side of a second focal point (BP) which is a focal point on the front side of the reflector (30), and a lens optical axis (O) of the lens (70) is inclined forwardly downward with respect to a lamp optical axis (Z) of the lamp.
