Vehicle lighting device

Abstract

A vehicle lighting device includes a projector lens, a lens holder, a main body barrel, a bottom cover, a first to a fourth excitation light sources, an upper and a lower light deflector, a correction mirror, and a fluorescent unit. The first and the second excitation light source emit laser beams toward the rotational center of a light-deflecting mirror of the upper light deflector, and the third and the fourth excitation light source emit laser beams toward that of the lower light deflector. The correction mirror corrects the distortion of the laser beams scanned by the upper and lower light deflectors and reflects the corrected laser beams. A two-dimensional image corresponding to a predetermined light distribution pattern is drawn as a white image on the fluorescent unit by the corrected light beams, and the two-dimensional image is projected on a virtual vertical screen through the projector lens.
