Abstract

An optical unit includes: a light source; a first reflector that reflects emitted light emitted from the light source, at a first reflection region of which the reflecting direction is periodically changed; and a second reflector that further reflects first reflected light reflected by the first reflector, at a second reflection region of which the reflecting direction is periodically changed. The first reflector is configured such that the second reflection region is scanned with the first reflected light. In the second reflector, the second reflection region is formed such as to reflect the first reflected light to provide second reflected light with which scanning is performed to produce a light distribution pattern.
