Problems solved by technology

[0006] When a pair of left and right light distribution patterns are integrally formed using such a vehicle lamp, if the two are partially overlapped, the brightness of the overlapping portion can be increased, but the maximum luminosity cannot be sufficiently increased.
In addition, in the case where a pair of left and right light distribution patterns are formed separately, it is impossible to sufficiently ensure the brightness of the side end portions of the respective light distribution patterns that are close to the centers of the two light distribution patterns.
Therefore, there is still room for improvement in fully improving the front visibility of the driver of the vehicle

Abstract

A vehicle lamp uses illumination light from a pair of lamp assemblies that can be rotated in the left and right directions to form a pair of left and right light distribution patterns, and can fully improve the forward visibility of the driver of the vehicle. Each lamp assembly includes first and second lamp units. Furthermore, a first light distribution pattern having a cut-off line (CLL, CLR) extending in the up-down direction is formed on the center side of a pair of left and right light distribution patterns (PL, PR) using the irradiation light from the first lamp unit of each lamp assembly. (PL1, PR1), and the irradiation light from the second lamp unit of each lamp assembly is used to form a smaller and brighter third light distribution pattern (PL1, PR1) at a position close to the cutoff line (CLL, CLR) than the first light distribution pattern (PL1, PR1). Two light distribution patterns (PL2, PR2).

Description

technical field [0001] The present invention relates to a lamp for a vehicle, which forms a pair of left and right light distribution patterns using irradiation light from a pair of lamp assemblies. Background technique [0002] Conventionally, as a structure of a vehicle lamp, it is known to form a pair of left and right light distribution patterns using irradiation light from a pair of lamp units. [0003] As such a vehicular lamp, "Patent Document 1" describes a vehicular lamp in which each lamp unit is rotatable in the left-right direction. [0004] Patent Document 1: (Japanese) Unexamined Patent Publication No. 2010-140661 [0005] By employing the vehicular lamp described in the aforementioned "Patent Document 1", a pair of left and right light distribution patterns can be formed integrally or separately. [0006] When a pair of left and right light distribution patterns are integrally formed in such a vehicle lamp, if the two are partially overlapped, the luminance ...
