SV18W-6S6P-2323

This is a KiCad PCB repository for a led arranged aluminium pcb.

Overview

This PCB is for a led lamp needing constant current of 1A and variable voltage around 14V to 21V.

Like its title suggest it consists of leds mounted in a 6 series times 6 parallel configuration.

I made this PCB, because on the net I did not find a applicable off the shelf replacement pcb, after one of these elements broke in my lamp.

This PCB and its components are not a exact replacement for the original since most informations about it were estimated/guessed.
