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.
