Driving three 12v 10 watt LED COB arrays
Apparently it requires WIDE Power traces and for the LED COB return to Mosfet Drain.

It's the best I could get AI tools to help me build. Used Kicad v9 for layout.

I think it's overly complex, not well thought-out, and not very safe for the LEDs.

What is the Comparitor supposed to do ?, with a Pot on the Input ???

And for that matter, what is the 4017 supposed to do ?

Have You already purchased any of the Components ?

Have You already purchased the Power-Supply ?, if so please describe it.

Please provide an EXTENSIVE and DETAILED explanation
regarding what this Circuit is supposed to do.

Please provide an EXTENSIVE and DETAILED explanation
regarding what will be TRIGGERING this Circuit.
( Preferably including a Schematic-Diagram if possible ).

If You have already chosen the LEDs, please provide a Spec-Sheet for them.

FYI AI is pretty hopeless for electronic design- because it cannot reason.
Be very wary of anything AI gives you

Did AI give you D2? it's backwards.

 

LQC makes perfect sense in post#2, with the valid questions!
AND the intended circuit operation is a bit hard to understand.
So an explanation of at least the intended operation will help others determine what the circuit shown is intended to do, which is not clear to me.
