VEHICULAR LIGHTING FIXTURE AND CONTROL METHOD OF THE SAME

Document Type and Number:

Japanese Patent JP2018008660

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To form a proper light distribution pattern following an inclination angle of a vehicle which changes in real time by a travelling environment.SOLUTION: A vehicular lighting fixture 2 for forming a predetermined light distribution pattern is constituted by: a light source (excitation light source 11) for radiating light; an optical system (light deflector 12) for forming the predetermined light distribution pattern; inclination angle calculation means (inclination angle calculation part 131) for calculating an inclination angle of a vehicle in which the vehicular lighting fixture is mounted with respect to a road surface; and light distribution pattern correction means (light distribution calculation part 132) for correcting a predetermined light distribution pattern based on the calculated inclination angle of the vehicle with respect to the road surface.SELECTED DRAWING: Figure 3
