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?
