LED bulb with AC 220v.

can any body help me???? I want to build a LED bulb with 220v AC. But the circuit should be very simple and short. I want to fix it in a dead Energy Saver (CFL). or can i use dead CFL's circuit with LEDS?

The cfl circuit boosts the 220 volts up to hundreds or thousands of volts (so that electrons literally jump through the low pressure gasses in the bulb).  That circuit is of practically no use to you. The housing and bulb socket are quite useful to you though.

Using leds with mains voltage is both possible and efficient if done properly:

(those two are run at mains voltage)

This one uses a cheap circuit to down the voltage from 110/220 to 4 volts for a luxeon led.

I don't need to warn you that ac220v is silly dangerous if not handled properly.

The second component in the second instructable is bridge rectifier, which can be used as a single component instead of connecting 4 discrete diodes.  Step 5 has explanation and picture about bridge rectifier.
