Abstract: A vehicle lamp is configured to form a predetermined light distribution pattern (such as a high-beam light distribution pattern) in which a plurality of irradiation patterns each provided with a non-irradiation region is superimposed. The vehicle lamp prevents an area of a common non-irradiation region from decreasing even if the non-irradiation regions formed in the plurality of respective irradiation patterns are displaced from each other. As a result, glare light is prevented from occurring to an irradiation-prohibited object. In the vehicle lamp configured to form the predetermined light distribution pattern in which the plurality of irradiation patterns each provided with the non-irradiation region is superimposed, the plurality of irradiation patterns is superimposed so that the non-irradiation regions are superimposed to form the common non-irradiation region, and the non-irradiation regions formed in the plurality of respective irradiation patterns have sizes different from each other.

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.
