Single LED on 230V

Hello,

A interesting montage is driving a led with main supply 240V.

Be careful because the LED powered at main supply 230V/50Hz

Here is a simplest LED AC mains Circuit

Schematic has few pieces:

we will use only 4 components:

1. 100nf Capacitor

2. 1K ohm Resistor

3. LED's * 2

4. 1N4004 diode.
