A vehicle lighting fixture (500, 600) can be configured to form a predetermined light distribution pattern by two-dimensionally scanning with light, wherein the predetermined light distribution can be formed with resolutions different in part, for example, in which the resolution in the horizontal direction is high at the center area and is gradually lowered toward the outer periphery from the center area. The vehicle lighting unit (500, 600) can include a light source (12); an optical deflector (201) configured to two-dimensionally scan with groups of spots (SP) of light having been incident thereon from the light source (12); a screen member (18) in which the light scanning by the optical deflector (201) forms a luminance distribution corresponding to a predetermined light distribution pattern; an optical system (20) configured to project the luminance distribution formed in the screen member (18) forward of a vehicle body; and an optical controlling member (502, 602) configured to change a pitch between spots (SP) in a group of spots (SP) among the groups of spots (SP) of light scanned by the optical deflector (201) on the screen member (18). |
