1. A circuit device, used to control a plurality of light-emitting devices disposed on an object, comprising:
a motion actuated switch, used to generate a trigger signal in response to a motion of the object; a controller, electrically coupled to the motion actuated switch; and a battery, used to supply the motion actuated switch, the controller, and the plurality of light-emitting devices with electrical power;wherein each light-emitting device comprises two light-emitting diodes connected oppositely in polarities, upon the controller receiving the trigger signal, the controller drives the plurality of light-emitting devices to light in a predetermined way by altering the output voltage polarities or values from the controller to the plurality of light-emitting devices. |
