I have a couple of 9W LED bulbs(1) at home with blown drivers. I got some replacement boards(3) with driver circuit and LEDs on the board itself. Now that the old LEDs(2) along with the aluminum PCBs are no longer required, I want to make a high power LED lamp which works on 230V AC. The LEDs are connected in series. With a working voltage of 3V each, I may require around ~76 LEDs (please correct me if I am wrong).
- Will a simple bridge rectifier and a filter capacitor do the job to light these LEDs?
- If yes, which values would you suggest for diodes and capacitor?
Another problem I may face is voltage fluctuation(not frequent) which may range from 200V to 250V. Am I wrong if I assume that this voltage fluctuation is not strong enough to damage the LEDs?
Any advice highly appreciated.
