AC Power LED Lightning

The Schematic shown below works for a 120v 50Hz supply . The capacitor is used to limit the AC Current through the  LED’s. The LED’s are arranged in two rows each containing 14 LED’s. A metal oxide resistor(1k ohm ,1W)  is connected in series to the capacitor to act as a fuse an to limit the peak current. The capacitor value (0.47uF ) for a 120 V supply keeps the current limited to about 20ma. When the device is powered by 240 V supply a 0.22uf ,400 V capacitor must be  used.
