Problems solved by technology

[0006] However, both of the left and right pair of light distribution patterns are formed by the irradiation light from the lamp unit using light-emitting diodes as the light source. Therefore, even if the two are partially overlapped, the maximum brightness cannot be sufficiently improved. There is room for improvement in front visibility

Abstract

Disclosed is a vehicle lamp including a pair of lamp modules configured to form a pair of left and right light distribution patterns by irradiation light therefrom. Each lamp module includes a first lamp unit that uses a light emitting diode as a light source and a second lamp unit that uses a laser diode as a light source, a pair of first light distribution patterns is formed by irradiation lightfrom the first lamp unit, and a pair of second light distribution patterns, which is smaller and brighter than the first light distribution patterns, is formed by irradiation light from the second lamp unit. The first light distribution patterns are formed with a predetermined distance therebetween in a left-and-right direction, the second light distribution patterns are formed to partially overlap each other between the pair of first light distribution patterns and to partially overlap the first light distribution patterns.

Description

technical field [0001] The present invention relates to a vehicle lamp configured to form a pair of left and right light distribution patterns by irradiation light from a pair of lamp units. Background technique [0002] Conventionally, as a structure of a vehicle lamp, a vehicle lamp configured to form a pair of left and right light distribution patterns by irradiation light from a pair of lamp units is known. [0003] "Patent Document 1" describes, as such a vehicle lamp, a vehicle lamp configured so that each lamp unit can turn in the left and right directions. [0004] [Patent Document 1] Japanese Patent Laid-Open No. 2010-140661 [0005] By adopting the vehicle lamp described in the above "Patent Document 1", a pair of left and right light distribution patterns can be formed integrally or separately. In addition, there is no glare to the driver of the oncoming vehicle or the driver of the vehicle driving ahead, and the forward visibility of the driver of the own vehic...
