You can operate any LED on 220 volt AC or 110 volt AC with this circuit You can use any capacitor according to your need I mention all capacitor voltage and current in this table , this circuit is working on 220 volt ac please don’t touch when it is on (Shock Hazard)
Circuit Diagram for LED on 220 Volt AC Supply
The C1 capacitor at the input forms the heart of the circuit and functions as the main current limiter component of the circuit. The current limiting function makes sure that the voltage applied to the LED never exceeds the required safe level.
However high voltage capacitors have one serious issue, these do not restrict or are not able to inhibit the initial switch ON mains power in rush, which can be fatal for any electronic circuit LEDs are no exceptions.
Adding a 10 To 56 Ohm resistor at the input helps to introduce some damage control measures, but still it alone cannot do the complete safeguarding of the involved electronics.
This is very simple to make and you can operate LED on 220 Volt ac with this circuit diagram
