With The help of this Simple AC LED Driver Circuit you can operate any LED on AC Votage 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)

Simple AC LED Driver Circuit Diagram

This is a Very Simple AC LED Driver Circuit for driving a 1 watt LED on 110, which may be understood with the following points.

The .47uf/400V capacitor at the input forms the heart of the circuit and functions as the main current limiter component of the circuit. You can use 1uf/400V capacitor for better performance. 

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 10-56 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.

CAUTION: THE CIRCUIT SHOWN IS NOT ISOLATED FROM THE AC MAINS, THEREFORE IS EXTREMELY DANGEROUS TO TOUCH IN POWERED POSITION

This circuit automatically turn on at night and turn off at day time. This is very effective, small and cheap circuit could be designed with ease. You can check also other circuit direct on 220 volt Continue Reading….
