Abstract
A vehicle lighting fixture can be configured to form a predetermined light distribution pattern by two-dimensionally scanning light 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 can include an optical deflector configured to two-dimensionally scan with groups of spots of light having been incident thereon from a light source; a screen member in which the light scanning by the optical deflector forms a luminance distribution corresponding to a predetermined light distribution pattern; an optical system configured to project the luminance distribution forward; and an optical controlling member configured to change a pitch between spots in a group of spots among the groups of spots of light scanned by the optical deflector on the screen member.
