LED on PCB with exposed copper introduce
A variant of LED on PCB has new performance
This is an optimized variant of MCPCBs where the metal of the metal plate partially protrudes through the insulation layer (Exposed Cu).
The housing is partly directly connected to the metallic carrier here for bridging the dielectric.
The theory of variant LED on PCB design
Here heat can be dissipated without requiring any insulation between the thermal pad, the metal layer and the heat sink.
This permits the LEDs to be operated at higher currents or higher power levels for example.
