Abstract
An lighting deviceincludes a light source, a reflector, an actuator, and a controller. The reflector has a first reflection surface that is concave recessed toward a direction away from the light source and is configured to receive light emitted from the light source. The actuator is configured to rotate the reflector with an axis passing through the light source being a rotation axis. The controller is configured to keep the light source on over a time shorter than a rotation period of the reflector according to a rotation angle of the reflector while controlling the actuator to rotate the reflector. A casting direction of light emitted from the first reflection surface is inclined with respect to an extension direction of the rotation axis.
