Kind Code:
A1
Abstract:
A rotary reflector (20) is configured to include a reflector main body (22) provided with six reflecting surfaces (22a), and an actuator for rotating the same. In addition, the configuration is such that, by selectively disposing any one of the six reflecting surfaces (22a) in a reflection control position, a rendering light distribution pattern is formed by means of reflected light from the reflecting surface (22a). Here, the reflector main body (22) has a configuration in which the shapes of effective reflecting regions (22a1 to 22a6) of the six reflecting surfaces (22a) are mutually different. Furthermore, six types of rendering light distribution patterns corresponding to the effective reflecting regions (22a1 to 22a6) are formed by rotating the reflector main body (22) through 60° at a time.
