Hi All,
I have a large LED array encased in resin, it might generate a lot of heat.. What if I had the negative go via a large block of exposed copper at the bottom of the board to which I attach a heatsink to. Is this electrically safe.. will have like 6V, 4A going through it...... Perhaps I have a non-electrically conductive, but heat conductive paste between heatsink and copper...
Just wondering how to dissipate heat if I have lots of LEDs in a matrix ( greater than 100 in one block with 5mm between each LED. The resin covers the board and a tiny bit of the LED casing.
