Title:
VEHICLE LIGHTING TOOL
Document Type and Number:
WIPO Patent Application WO/2021/141052
Kind Code:
A1
Abstract:
Provided is a vehicle lighting tool capable of appropriately forming an on-coming vehicle passing light distribution pattern and a traveling light distribution pattern using light from a first light source and a second light source while providing these light sources on the same substrate. A vehicle lighting tool 10 is provided with: a first light source 11 for emitting light L1 that forms an on-coming vehicle passing light distribution pattern LP; a second light source 12 for emitting light L2 that forms a traveling light distribution pattern HP; a projection lens 17 for forming the on-coming vehicle passing light distribution pattern LP by projecting the light L1 to the front side in the front-rear direction in which a lens axis La extends and for forming the traveling light distribution pattern HP by projecting the light L2 to the front side in the front-rear direction; and a substrate 18 on which the first light source 11 and the second light source 12 are provided. The respective outgoing light axes Li of the first light source 11 and the second light source 12 are parallel to each other. The first light source 11 and the second light source 12 are inclined at inclination angles with respect to the front-rear direction. The second light source 12 is disposed at a position away from the projection lens 17 relative to the first light source 11 in the front-rear direction.
