I see that LED light is replacing nowadays every old style light. I open one LED bulb and found that had a little SMPS inside it. Those convert AC line voltage to DC to supply the LED.
Wondering we can design to connect LED's on directly on AC line . It will improve efficiency
As per attached circuit. If we can connect LED on Direct AC line
- Will it work?
- Will it be safe and reliable?
- Whether it needed any limiting resistor, since all AC line voltage will be drop on LED . (Vline = 230 V AC, Vp = 230 * 1.414 (+15% tol) = 360 V approx. Total no led is 120 (changed 76 to 120), each led has 3V forward drop).
- How much line fluctuation will effect on LED?
