220 volts AC mains voltage and low current LEDs can operate with a simple circuit
CAUTION Be careful is working with high voltage capacitor circuit connections Beware + – If you connect the high voltage polarity may be large explosions before running the insured Power Line circuit, protective goggles.
low material cost quite a simple circuit :) 1 1N4007 diode least two pieces in 33k resistor and a second power SMD LEDs in a tiny circuit is made with materials that would
Did an experiment using the following calculation on page 5 pcs white LEDs were used for the material is not considered a good example of a somewhat rough circuit again direct 220 volt mains voltage diode bridge 400v 4.7uF capacitor to filter I’ve added straightened with
Each section = 5 = 3 LEDs Voltage (volts) LED Current (mA) = 25 = 310 input voltage (volts DC)
