Abstract:
1. A circuit device for being embedded in an object, said circuit device comprising: N light-emitting devices, N being an integer larger than 2, and each of the N light-emitting devices comprising a package, a lead set, a first light-emitting diode, and a second light-emitting diode, wherein the first light-emitting diode and the second light-emitting diode are both encapsulated in the package and the lead set is electronically connected to the first light-emitting diode and the second light-emitting diode; a motion-actuated switch, for generating a control signal in response to a motion of the object; a controller storing a plurality of lighting sequences and electrically connected to the motion-actuated switch and the lead set of each of the N light-emitting devices, the controller selectively driving each of the N light-emitting devices based on one of the plurality of lighting sequences when receiving the control signal; a power source, for supplying said circuit device with electrical power; a water-proof and dust-proof enclosure, for sealing the motion-actuated switch, the controller, the power source, and a first end of the lead set of each light-emitting device; and a regulating switch electrically connected to the controller for, based on the strength of a physical parameter, selecting the one of the plurality of lighting sequences stored in the controller for the controller to drive each of the N light-emitting devices.
