Led driver with dim function, Electrical Engineering

Assignment Help:

I´m looking for some help to identify some electronic parts, i have this led driver with preset dim levels that i can reach with switching the power on and off. The driver worked really well but it failed due to water damage, i''m reconstructing it now, but i need to identify a few parts and looking for help with this. I have a circuit diagram with almost all parts identified.
