Title:
VEHICULAR LIGHTING FIXTURE
Document Type and Number:
Japanese Patent JP2019175706
Kind Code:
A
Abstract:
To provide a vehicular lighting fixture which performs light distribution control by a parabolic reflecting surface of a reflector and can be reduced in size and weight.SOLUTION: A vehicular lighting fixture includes: a reflector 10 which has a reflecting surface 11; and a light source 20 which irradiates the reflecting surface 11 with light. The light source 20 has a first light emitting section 23B for applying light for low beam light distribution and a second light emitting section 23C for applying light for high beam light distribution. The light emitting section 23B is located at a focal point O of the reflecting surface 11 while the second light emitting section 23C is located on a front side of the first light emitting section 23B and is arranged to be offset on a hot zone HZ side of a low beam light distribution pattern on a screen formed by light from the first light emitting section 23B rather than a first reference line L1 when a line passing the focal point O and extending in a longitudinal direction is defined as the fist reference line L1. The reflecting surface 11 is formed into a surface shape for forming the low beam light distribution pattern by light from the first light emitting section 23B.SELECTED DRAWING: Figure 5
