How to connect a LED to 220 VAC

To find out how to connect a LED to the 220 VAC should follow two basic rules. The first thing you need to limit the current flowing through the LED. Second - you need to protect it from the effects of the reverse voltage at the halftime, when the LED is energized. To limit the current to an alternating voltage can be applied not only resistors, capacitors and inductors. To protect the LED from reverse voltage is enough to connect to it simultaneously in the opposite direction of normal diode or a LED. The video shows the calculation of current-limiting elements on the example of the two LEDs. The first type of AL307, the second LED 1 Watt.
