Circuit Diagram for AC LED Light
Resistor=240v -( Number of LEDs *3.3)/0.015 A =240 - (41*3.3)/0.015 A =7000 Ohms
Either use 6.8k or 7.1 K with power rating of 7-10 watt or 4*2.1 k 2watt
Suggested Layout for AC LED Light
- Take any old CFL lamp and cut open it. Remove the circuit out and use it as a back case.
- Make holes for the led as shown in the suggested layout. Fit the led’s in it and solder it in series.
- Solder the bridge and resistor as shown above in the ac led light circuit.
- You can use any plastic or wooden plate used in electrical wiring readily available in electrical shops.
Note: If input AC voltage is 120, adjusted the resistor value using the formula given above.
