Abstract: A lens body includes a first lens portion and a second lens portion and is configured such that light from a light source exits through a first exit surface of the first lens portion after being partially blocked by a shade of the first lens portion, further exits through a second exit surface of the second lens portion, thereby forming a predetermined light distribution pattern by the shade, wherein the first exit surface is a surface for condensing the light from the light source that exits through the first exit surface with respect to a first direction and is configured as a semicircular cylinder surface, and the second exit surface is a surface for condensing the light from the light source that exits through the second exit surface with respect to a second direction orthogonal to the first direction and is also configured as a semicircular cylinder surface.

Abstract: A headlight device provided enables horizontally displacing of the irradiation region for scanning of scanning light by a light deflector without problems. The light deflector includes: a mirror unit that reciprocally turns about first and second rotation axes at first and second frequencies. The first frequency is a natural-oscillation frequency of the mirror unit, and the second frequency is lower than the first frequency. Directions of the first and second rotation axes are set so that scanning directions of the reflect light due to the reciprocal turning of the mirror unit about the first and second rotation axes are in the directions of vertical axis and horizontal axis, respectively. The control unit controls reciprocal turning of the mirror unit about the second rotation axis based on driving voltage obtained by superimposing offset voltage with basic driving voltage having an increasing and decreasing waveform.

Abstract: A vehicle lighting fixture can form a predetermined light distribution pattern at a position horizontally or vertically shifted with respect to a reference position. The vehicle lighting fixture include: a light source; an optical deflector configured to include a mirror part; a rotary reflecting member configured to reflect light having been reflected by the mirror part of the optical deflector; a screen member configured to form a luminance distribution by the light reflected by the rotary reflecting member; an optical system configured to project the luminance distribution formed in the screen member to form the predetermined light distribution pattern; and a rotary control unit configured to control the rotary reflecting member to form the luminance distribution at a reference position or a position shifted with respect to the reference position. The rotary control unit can control any of the rotational direction and the rotational amount of the rotary reflecting member.
