Vehicle headlight device

A vehicle headlight device comprising:

• a first illuminating unit that includes a first mirror that rotatingly operates, the first mirror reflecting laser light that has exited from a laser light source, making the laser light into scanning light, and illuminating the scanning light toward a first illumination region that is in front of a vehicle;
• a second illuminating unit that includes a second mirror that is an aggregate of a plurality of micro mirrors having angles that can be changed, the second mirror reflecting visible light that has exited from a visible light source, and illuminating the reflected light toward a second illumination region that is in front of the vehicle;
• a controlling unit that controls turning-off and turning-on of the laser light source, rotating operation of the first mirror, and changing of the angles of the micro mirrors at the second mirror;
• and
• a third illuminating unit configured to illuminate visible light, which has exited from a visible light source, toward a third illumination region that is closer to the vehicle than the first illumination region,
• wherein the first illuminating unit is configured to illuminate a portion of the third illumination region, which is to be illuminated by the third illuminating unit, so that the scanning light from the first illuminating unit forms a cut-off portion of the third illuminating region.
