VEHICULAR LIGHTING SYSTEM

摘要

PROBLEM TO BE SOLVED: To prevent generation of a dark part between mutual left and right light distribution patterns while improving turning directional visibility at vehicle turning time without adding a light distribution part. SOLUTION: This vehicular lighting system has a pair of left and right movable light distribution parts 7 and 9 capable of changing a light distribution state by irradiating the front of a vehicle, horizontal directional rotary parts 11 and 13 for separately rotating the light distribution state of the movable light distribution parts 7 and 9 in the lateral direction, vertical directional rotary parts 15 and 17 for separately rotating the light distribution state of the movable light distribution parts 7 and 9 in the vertical direction, diffusion adjusting parts 19 and 21 for adjusting an extent of the light distribution state of the movable light distribution parts 7 and 9 and a steering wheel steering angle sensor 27 for detecting a steering angle of the vehicle, and according to a detecting value of the steering wheel steering angle sensor 27, a controller 1 controls driving of the horizontal directional rotary parts so as to rotate the turning directional side movable light distribution part of the vehicle in the turning direction, controls driving of the vertical directional rotary parts so as to rotate the movable light distribution parts in the upward direction, and controls driving of the diffusion adjusting parts so as to diffuse the light distribution state of the unturning directional side movable light distribution part.
