Abstract: An optical reflecting device includes a mirror part, a pair of joints, a pair of vibration parts, a plurality of driving parts, and a fixed part. Each of the joints has a first end connected to respective one the facing positions to each other on the mirror part and a second end opposite to the first end, and extends along a first axis. Each of the vibration parts has a central portion connected to the second end of respective one of the joints. A plurality of driving parts is disposed in each of the pair of vibration parts, and rotates the mirror part. Both ends of each of the pair of vibration parts are connected to the fixed part. The beam width defined as the length of each of the joints in a direction orthogonal to the first axis is greater than the beam width of each of the pair of vibration parts.

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: An actuator includes a frame, a driver portion having one end connected to an inside of the frame, a movable portion connected to another end of the driver portion, and an electrode provided at the movable portion. The driver portion vibrates the movable portion by being driven by a driving signal. The electrode receives a high-frequency signal higher than that of the driving signal. This actuator is driven at a high speed by a large deflection angle, and can prevent dust from adhering to the movable portion.
