Abstract
A light body includes a counting and control unit which counts a switching number of a switch element, and outputs a corresponding enable signal to a driving and light-emitting module to emit light of a selected feature according to the switching number of the switch element. The light body further includes a bridge current rectifying unit in communication with the switch element for converting alternating current received from the power source into direct current. For allowing two or more light bodies to be synchronously controlled, the switching signal indicative of the counted switching number is substantially simultaneously transmitted to the counting and control unit of each of the light bodies without passing through the bridge current rectifying unit.
