It adopts an aluminum substrate to boost heat dissipation and mechanical strength. And the copper layer is isolated via the insulated layer, to ensure the LED current is well distributed. The structure supports high lumen density, meanwhile, keeps junction temperature low, ensuring the long-term stability of the brightness and colors. <\/p>\n\n\n\n<p>In comparison with <a href=\"https:\/\/www.bestpcbs.com\/products\/HDI-board.htm\">traditional FR4<\/a>, the aluminum substrate conducts heat faster, which allows LEDs to be placed in high density for a compact space. Besides, the metal base improves rigidity and vibration tolerance.

A thin thermal pad bridged the back to the cast housing. Junction temperature dropped by 16\u201322 \u00b0C in the worst case. <\/p>\n\n\n\n<p>It has the key wins that it has less heat at the LED. Cleaner color over life. Higher yield at <a href=\"https:\/\/youtu.be\/7CqV1RhM4to?si=sLRa5MGpbXhDmRnA\">SMT<\/a>. And no tooling changes.
