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.

Automatic Light Alignment

A system may have lights. The lights may be moved using a positioner. Control circuitry may use sensor circuitry to monitor the environment surrounding the system. The sensor circuitry may include one or more sensors to measure the shape of a surface in front of the system and the location of the surface relative to the system. The sensor circuitry may also measure light illumination on the surface. Based on the known shape of the surface in front of the system and the distance of the surface from the system, the control circuitry can predict where a light should be aimed on the surface. By comparing predictions of light illumination on the surface to measurements of light illumination on the surface, the system can determine how to move the light with the positioner to align the light.
