Thanks Johnkey, I borrow your pic here… [image] The copper board works unexpectedly way better than predicted. From many tests performed in BLF, we knew the tighter the LED pitch the hotter it gets. Not only because the copper trace surface area needed to shed the heat from the LED base reduced, but also due to the “photon cross talk” as mentioned by Nichia in their application notes. The LED takes and recycle the photon from the neighboring LEDs and the stored photon, instead escaping as ligh…
