Abstract:
An actuator for driving a reflector includes a movement frame, a first support frame, a first drive coil, a first rotation guide and a first ball. The movement frame includes a reflector configured to reflect or refract light to a lens and a first magnet. The first support frame is configured to provide a space of the movement frame to move. The first drive coil is configured to generate an electromagnetic force in the first magnet to rotationally move the movement frame in a first direction based on the first support frame. The first rotation guide is arranged between the movement frame and the first support frame and has an arc shape so that the movement frame rotates in the first direction. The first ball is arranged inside the first rotation guide, wherein a center of curvature of the first rotation guide corresponds to a center of rotation of the reflector.
