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

The present invention relates to lamps for vehicles. The object is to improve the front visibility of the driver of the own vehicle in a vehicle lamp configured to form a pair of left and right light distribution patterns by irradiation light from a pair of lamp units. Each lamp assembly is composed of a first lamp unit using a light emitting diode as a light source and a second lamp unit using a laser diode as a light source, and a first light distribution pattern (PL1, PR1) is formed by the irradiated light from each first lamp unit. The irradiated light of each second lamp unit forms a second light distribution pattern (PL2, PR2) smaller and brighter than the first light distribution pattern (PL1, PR1). The pair of first light distribution patterns are formed at a required interval in the left and right direction, so that the pair of second light distribution patterns (PL2, PR2) are formed between the pair of first light distribution patterns (PL1, PR1) They are formed in a state of partially overlapping with each other and partially overlapping with a pair of first light distribution patterns ( PL1 , PR1 ).

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 irradiated light from a pair of lamp units. Background technique [0002] Conventionally, as the structure of a vehicle lamp, a vehicle lamp in which a pair of left and right light distribution patterns are formed by irradiated light from a pair of lamp assemblies is known. [0003] "Patent Document 1" describes, as such a vehicle lamp, a vehicle lamp configured such that each lamp unit can be rotated in the left-right direction. [0004] [Patent Document 1] JP 2010-140661 A [0005] By using the vehicle lamp described in the aforementioned "Patent Document 1", a pair of left and right light distribution patterns can be formed integrally or separately. And, as a result, no glare is given to the driver of the oncoming car or the driver of the car driving ahead, and the front visibility of the driver of the own car can be ensured. [0006] How...
