Abstract:
1. A circuit device for an LED's driving and stabilizing system, comprising: an AC/DC controllable driving voltage source for externally connecting to an AC voltage source of a public power supply and converting the public AC voltage source into a DC voltage source for supplying to LEDs and other associated circuit elements in the LED driving and stabilizing system; an LED modulation driving controller controllable voltage source for further supplying the LEDs and other associated circuit elements in the LED driving and stabilizing system with an active and stable power source having conditions set through overall selectivity when the AC/DC controllable driving voltage source has converted the public AC voltage source into a DC voltage source; a feedback driving controller being actuated to start operating when the AC/DC controllable driving voltage source has been connected to the public AC voltage source, so as to provide short-circuit protection and polarity reversal protection to the circuit device; and the feedback driving controller having an internal control circuit capable of automatically detecting, comparing, and determining a circuit state of an LED modular device having conditions set through overall selectivity; an external regulator connected to an outer side of the circuit device for externally inputting a control signal source (I/O) to the circuit device; and an LED modular device for illuminating purpose connected to the circuit device.
