Overcurrent Protection for COB Leds wired in parallel powered by Const Voltage Mean Well Driver
First off, the Mean Well driver you named is a constant current driver. 

You shouldn't be driving LEDs in parallel from a constant current source.

You should have LEDs in series to reach the voltage range of the current source.  Since your COBs already have LEDs in series to make up 36V, you need one driver for each COB.

The named driver is overkill for a single COB, and driving the COBs in parallel is asking for trouble.  You've already discovered the problems, hence your question.

The correct thing to do would be to use a driver for each COB, and each driver matched to the current needed for each COB.  Doing otherwise is just looking for problems, and it will probably be  more expensive and still not do an adequate job if one of the COBs dies (or just loses contact for a moment.)
