Hi, this might be a really stupid or easy question for u all out there.
The thing is, I have very little idea about all this. I have made four boards with 72 white LEDs connected in series in each of them. The AC supply in my place is about 220v. Now, if I connect any of these boards to my AC source, they light up but flicker(obviously). So, I guess I need to use a rectifier? Is it necessary to use a capacitor and filter the output? I want to use one rectifier and connect two boards in parallel with it. That is, total of four LED boards with 72 white LEDs each in them and two rectifiers.
So, from the power supply circuit, I guess I will be needing output of 40mA. Would be really great if you can help out and guide me with the power supply circuit design.
I am planning to install the LED circuits in a place where it will be really difficult to replace them. Hence, I need such a solution which ensures that the life of the LEDs is maximum. The rectifier circuit will however be placed away from the LED circuit so that the rectifier can be changed easily.
Thanks.
