A driving device of an embodiment includes a first rotational unit and a holding unit. The first rotational unit is disposed with an object to be operated on one surface side intersecting with a first rotating shaft, and rotationally moves around the first rotating shaft with the object to be operated. The holding unit is disposed on another surface side of the first rotational unit, rotates with the first rotational unit, and holds a cable for supplying power to the object to be operated at a position away from the first rotational unit toward the other surface side, while placing the cable along the first rotating shaft.

A luminaire that includes a lamp head that is magnetically connectable to a support, is configured to rotate to any desired angle or orientation and is detachable from the support to allow for the lamp head to be a hand-held light.
