Document Type and Number:

WIPO Patent Application WO/2019/186523

Kind Code:

A1

Abstract:

This vehicle light fixture is equipped with a reflector (10) having a reflection surface (11), and a light source (20) for emitting light toward the reflection surface (11). The light source (20) is equipped with a first light emitting unit (23B) that emits light for low-beam light distribution and a second light emitting unit (23C) that emits light for high-beam light distribution. The first light emitting unit (23B) is positioned at the focal point (O) of the reflection surface (11). The second light emitting unit (23C) is positioned further forward than the first light emitting unit (23B), and is disposed, with respect to a first reference line (L1) extending through the focal point (O) in the front-back direction, so as to be offset from the first reference line (L1) toward the hot zone (HZ) side of a low-beam light distribution pattern formed upon a screen by light from the first light emitting unit (23B). The reflection surface (11) is formed with a surface shape that forms the low-beam light distribution pattern using light from the first light emitting unit (23B).
