The above picture shows the silicon controlled capacitance step-down LED drive circuit.In this circuit, silicon controlled SCR and R3 constitute protection circuit, when the current flows through the LED more than the setting , SCR conducts certain Angle and the circuit's current are divided and it makes the LED work in stable condtion,which keep the LEDaway from high voltage damage.
