Transformer less 6v smd led driver circuit?
Hi, I have buy a 6V smd led board which have12leds. Now I what to make a cheap transformer less power supply that light it in 220v ac mains. I try with a 474k capacitor with 100k resistor parallel and 4 dioads and a 1k resistor connect to the positive dc output . It works but the light of led is too low. I want a circuit like in led bulbs to drive them. Thank you.
