Abstract
A lighting device is composed of a case, a driving device, a power source contacting device, a power source rotary device, an actuating arm, and at least a light ball. When the power source is turned on to light up the lighting device, the motor of the driving device starts to rotate the rotary device and the actuating arm synchronously. Accordingly, the lighting ball is rotated horizontally. In addition, a gear disk of the light ball rolls along a gear ring on the case such that the light ball can rotate vertically as well.
