Abstract
An angle adjuster is configured by disposing a first driver for driving a horizontal rotation frame (horizontal direction rotator) to rotate in the horizontal direction and a second driver for driving a vertical rotation frame (vertical direction rotator) to rotate in the vertical direction on the horizontal rotation frame. This configuration can reduce the size of the angle adjuster and a lighting apparatus with the angle adjuster.
Claims6
An angle adjuster for adjusting an angle of an operation target, the angle adjuster comprising:
- a frame body;
- a horizontal direction rotator that is rotatably supported in a horizontal direction by the frame body;
- a vertical direction rotator that is rotatably supported in a vertical direction by the horizontal direction rotator, wherein the operation target is fixed to the vertical direction rotator;
- a first driver that drives the horizontal direction rotator, the first driver including a first motor as a drive source and a first gear mechanism that transmits drive power of the first motor to the horizontal direction rotator;
- and
- a second driver that drives the vertical direction rotator, the second driver including a second motor as a drive source and a second gear mechanism that transmits drive power of the second motor to the vertical direction rotator, wherein:
- the first driver and the second driver are mounted to the horizontal direction rotator through a structural element and disposed symmetrically with respect to a center line of the operation target;
- and
- components of the first driver and components of the second driver are same type of components.
