摘要： An LED control circuit for controlling an LED illuminating device is disclosed. The LED illuminating device includes at least serially connected load group, and the LED control circuit includes: a conversion module configured to convert an input voltage to an output voltage, and to output a working current as a sample current; a reference voltage generating module configured to generate a reference voltage; a control module configured to compare a sample voltage corresponding to the sample current with the reference voltage, and to output a control signal to the conversion module according to a comparison result; and a load short circuit module including a plurality of switches each connected in parallel with respective load group for performing a short circuit control on respective load group in response to a switching signal. A controlling method of such LED control circuit is also disclosed.
