    摘要: An accelerating circuit increases the speed of an LED (light-emitting diode) by controlling an LED driving circuit. The LED driving circuit includes two driving transistors. The accelerating circuit includes a pair of series-connected switch units and a pulse generator. The two switch units respectively connect to a first electronic source and a second electronic source. A node point where the two switch units connect together is coupled to a cathode of the LED. The pulse generator includes two input terminals to receive a pair of driving signals to control the switch units to be connected/disconnected in accordance with a pair of output pulse signals of different timing. When the switch units are connected, the two electronic sources can generate forward pulse current/reverse pulse current to deliver the forward pulse current/reverse pulse current to the LED to turn on/off the LED quickly.
