230V AC Mains supply limited by using Polyester Capacitor C1 ( 1µF/400V ) and Resistor R1. Limited Voltage and Current through these elements Rectified by using Bridge Rectifier. Here AC voltage converted into DC Supply, RV1 Varistor used to protect the following Circuit from High voltage surges.

DC Supply from Bridge Rectifier is filtered by C2 Capacitor and Regulated by Reverse biased Zenzer diode. 1W White LED or high bright warm 8mm white LED connected in series and then connected with output terminals that is across to the Zener diode. Depends on our requirement we can Increase or decrease the numbers of LED in array. Before connecting LEDs in an array make sure about the LEDs Anode and Cathode terminals.
