COB LEDs look simple. But they quietly changed how luminaires are built. Instead of assembling dozens of discrete LEDs first, COB mounts multiple chips directly onto the MCPCB.
The result: • Lower thermal resistance • Higher power density • Fewer assembly steps • Better system-level consistency
This is why many high-power luminaires are moving toward:
COB module → luminaire
instead of
SMD LEDs → MCPCB → luminaire
What’s interesting is this: COB doesn’t always win on unit price. But it often wins on system cost, yield, and long-term reliability.
And that’s where many sourcing discussions get uncomfortable.
So here’s the real question: When choosing between COB and SMD, what actually drives your decision, BOM cost, optical control, thermal margin, or production yield?
