CX reduces high voltage AC from mains to a low voltage AC which is rectified by the diodes D1-D4. Capacitor C1 removes ripples from AC so that low voltage DC is available to power the LEDs.CX is the X rated AC capacitor that reduces AC voltage through capacitive rectance property. Resistor R1 is very important to remove the stored voltage from ...
