Hello, I would like to extend the circuit of the attached picture x4. From a tiny LED that goes on/off at the top of the circuit I turn on/off a power LED. I would like to light on/off x4 POWER LEDS. Apart from changing my power supply with x4 more current, what other components have to be added 4 times?

I suspect the following?

4x Resistor 10k
4x Resistor 5W
4x MOSFET FU9024
4x POWER LEDs

Do I also need x4 PC 817 ?
Can someone advise or make a change on my circuit? Thanks a lot in advance.
 

There's no need to add 3 mosfets, that one will handle the current. Just add 3 leds and 3 Rs (or 1 higher power R)
 

thanks for the answer! Do I have to add only the 27R 5W resistor 3 times or also the 10k one?
thanks
 

The 10K is a pullup for the optoisolator, which (I assume) is an open-collector output, you only need the one resistor.
 

Thanks a lot for the answer. so, you think a schematic like the one attached will work?
