Summary:The utility model discloses a novel LED driving topological circuit, comprising a DC power supply, a transformer, an LED control chip, an internal voltage stabilized power supply, a first capacitor, a second capacitor, a resistor, a field effect transistor, a first diode, a second diode, a first light emitting diode, and a second light emitting diode. When the circuit is started, input power passes through a tap of a primary first coil of the transformer, and then passes through the second diode, and charges the first capacitor by the internal voltage stabilized power supply in the LED control chip. When voltage of the first capacitor reaches a normal voltage value, the LED control chip is driven to start operation. The LED driving topological circuit is improved on an existing LED driving topological circuit, thereby effectively improving working efficiency and reducing power consumption of the circuit, and slowing down aging of the LED device. The LED driving topological circuit plays a role of protecting t
