Abstract:
1. A vehicle lighting unit, comprising: a light source; a reflecting member configured to reflect light from the light source toward an illumination area in front of a vehicle body; an actuator configured to turn the reflecting member around a first axis and a second axis so that the illumination area in front of the vehicle body can be vertically and horizontally scanned with the light reflected by the reflecting member; an actuator controller configured to control the actuator such that a scanning frequency of the reflected light in a vertical direction is larger than a scanning frequency of the reflected light in a horizontal direction; and a light intensity controller, wherein the actuator controller controls the actuator so that upper turned edges of scanning in the vertical direction are located above a cut line of the illumination area, and the light intensity controller is configured to control the light source during the vertical scan period such that the light source is turned off during a period during which a light spot formed by the light source is located above the cut line.
