    • The invention is provided with an LED driving device and the control method. The driving device includes power converter, microprocessor and LED circuit. Wherein the power converter includes impulse transformer and switch control circuit. Primary winding at input side of the impulse transformer connects with rectifier filter circuit by the switch control circuit. Secondary winding at output side and auxiliary winding connect with power end of the microprocessor by constant voltage control switch. Output end of the microprocessor connects with LED circuit. The LED driving device and the control method provided by this invention collects on/off signal of mechanical lamp by using switch control circuit. Light is adjusted by LED circuit driven by the microprocessor, and thus heat elimination effect is improved, power consumption is lowered and brightness is enhanced.
