摘要：An LED control circuit for controlling an LED illuminating device is disclosed. TheLED illuminating device includes at least serially connected load group, and the LEDcontrol 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 voltagegenerating module configured to generate a reference voltage; a control moduleconfigured to compare a sample voltage corresponding to the sample current with thereference voltage, and to output a control signal to the conversion module according toa comparison result; and a load short circuit module including a plurality of switches eachconnected in parallel with respective load group for performing a short circuit control onrespective load group in response to a switching signal. A controlling method of such LEDcontrol circuit is also disclosed.
