COB vs SMD for High-Power Airport Lighting
Which is Right for High-Power Airport Lighting?
A professional comparison on thermal performance, lumen maintenance, glare control and long-term reliability.
Helping designers and owners make clearer technical decisions for terminal and apron projects.
The comparison above focuses on high-power (especially above 100 W) airport lighting applications. Actual performance still depends on the complete optical, driver and thermal system design.
Why COB Technology Is Better Suited for Airport Lighting
High Power Demand
Terminal halls and aprons require high light output. COB makes it easier to achieve high power density in a single source, reducing the number of luminaires.
Long-term Reliability
Airport lighting demands extremely low lumen depreciation and failure rates. Low-junction-temperature COB design better supports decade-long stable operation.
Consistent Anti-Glare
A single light-emitting surface makes deep anti-glare optics easier to control precisely, delivering more stable UGR performance in large public spaces.
Advantages of KWCOB’s COB Technology
KWCOB does not merely use COB — we solve the core challenges of high-power COB from the source:
- Independently invented kilowatt-class COB packaging technology
- Transparent ceramic phosphor with low light decay at high temperature
- Phase-change heat dissipation + optical-electrical-thermal integration
- Publicly released LM-80 data for 120 W / 300 W / 600 W
- OPM project-level customisation with precisely matched optics and thermal management
These capabilities allow COB to deliver its full advantages of long-term reliability, low glare and low maintenance in airport applications.
