A Light Emitting Diode (LED) driving circuit includes a power supply circuit, an LED circuit, and a switch control circuit. The power supply circuit includes an energy storage device and a switch component connected to the energy storage device. The energy storage device stores electric power when the switch component is switched on. The LED circuit is connected to the energy storage device. The switch control circuit is connected to the switch component, and is adapted to control the on/off states of the switch component, thereby adjusting a current flowing through the LED circuit. |
