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

Disclosed is a vehicle lamp a pair of lamp modules configured to irradiate light to form a pair of left and right light distribution patterns. Each of the lamp modules includes first and second lamp units. Further, irradiation light from the first lamp unit forms a first light distribution pattern having a vertically extending cutoff line at a center side of a pair of left and right distribution patterns, and irradiation light from the second lamp unit forms a second light distribution pattern near the cutoff line. The second light distribution pattern is smaller and brighter than the first light distribution pattern.

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 ...
