| titleOfInvention | LED driving system high in safety factor |
| abstract | The invention discloses an LED driving system high in safety factor. The LED driving system is mainly composed of a bandpass filter circuit, a driving circuit and an amplifying circuit connected with the driving circuit. The LED driving system is characterized in that an overvoltage and overcurrent protection circuit is further arranged between the bandpass filter circuit and the driving circuit; the overvoltage and overcurrent protection circuit is composed of a protection chip U2, a triode VT1, a triode VT2, a triode VT3, a capacitor C3, a diode D2, a capacitor C4, a resistor R5 and the like, the anode of the capacitor C3 is connected with a CONT pin of the protection chip U2 while the cathode is connected with the bandpass filter circuit, the N-pole of the diode D2 is connected with the VCC pin of the protection chip U2 while the P-pole is connected with the TRI pin of the capacitor C3, and one end of the resistor R5 is connected with the OUT pin of the protection chip U2 while the other end is connected with the base of the triode VT3. The overvoltage and overcurrent protection circuit can make protective action automatically during current or voltage overload on an LED load, and the LED load and the driving system can be prevented from being damaged. |
