how can i light or join together 10 or more led lamps to 220 volt current , like the led lamp bulb?
Cluster LEDs are quite common. If you connect LEDs in series, allow about 1V drop for each and then use a resistor to limit the current to about 10milliamps.
So, 10 LEDs in series requires a resistor thus:
(220 - 10) / 0.01 = 21000 ohms @ 3Watts
