Re: I Don't Understand
Is it really pulsing? What is the ON time and OFF time of the pulse being applied to the LED's?
And are you using that constant current source circuit as you have shown to drive the LED's?
What did you use to limit the current to the LED's? Just remember that LED is current device, you have to manage the current flowing through it, you do not hook them up to constant Voltage source and hoping it will not blow up, you use constant current source to drive LED.
That power supply board looks like capacitive dropper type.
Are there any parts on the bottom side of the board.
