    Abstract: A light control system includes an optical reflection element and a controller. The optical reflection element includes: a reflector; and a first swing portion and a second swing portion disposed at respective one of positions sandwiching the reflector. Each of the first swing portion and the second swing portion includes: a first connection portion coupled to the reflector; a first vibration portion; a second vibration portion; a first drive portion; a second drive portion; and a second connection portion that connects the first and second vibration portions to a base. The controller causes the first and second drive portions of the first swing portion to vibrate in the same phase, and causes the first and second drive portions of the second swing portion to vibrate in the same phase but in the opposite phase to the first swing portion.

    Abstract: A driving element includes: a base; a movable part spaced apart from the base in a direction parallel to a rotation axis; a connection part connecting the base and the movable part; a pair of first arm parts extending in a first direction parallel to the rotation axis with the rotation axis located therebetween; a pair of second arm parts extending in a second direction opposite to the first direction, with the rotation axis located therebetween; a coupling part coupling the pair of first arm parts and the pair of second arm parts to the connection part; and a piezoelectric driver disposed on at least either the pair of first arm parts or the pair of second arm parts.
