車両用灯具
Document Type and Number:
Japanese Patent JP6966878
Kind Code:
B2
Abstract:
To enable the formation of a light distribution pattern having a high central luminous intensity without generating stray light in a vehicular lighting fixture including a plurality of lighting fixture units configured so as to perform reflection control of an outgoing beam from a light-emitting element with a reflector.SOLUTION: Three lighting fixture units 20A, 20B, 20C arranged in a vehicle width direction are arranged in a positional relationship in which outgoing beams from a light-emitting element 22A of the lighting fixture unit 20A located outside in a vehicle width direction can reach a reflector 24C of the lighting fixture unit 20C located inside in the vehicle width direction through a rear side space of the reflector 24B of the lighting fixture unit 20B adjacent to the lighting fixture unit. This secures a long distance for the outgoing beams from the light-emitting element 22A to reache the reflector 24C, enhances distant visibility by making the central luminous intensity of a light distribution pattern formed by its reflection light, and eliminates a risk that part of the outgoing beams from the light-emitting element 22A are reflected on the reflector 24B to generate stray light.SELECTED DRAWING: Figure 1
