Thermal engineering
Why COB LED Heat Sinks Require Specialized Engineering
COB LEDs concentrate significant heat in a small footprint. Effective cooling depends on the relationship between base thickness, fin density, airflow path, and mounting interface.
Our engineering team evaluates heat load, ambient conditions, and available space to recommend the right cooling architecture for your application.
Heat load analysis
Review the thermal load and operating environment before selecting the cooling structure.
Geometry selection
Balance base thickness, fin density, aspect ratio, and airflow for the available space.
Interface design
Account for mounting requirements and the thermal interface between the COB module and sink.
Production fit
Choose a process that supports thermal targets, required volumes, and cost objectives.
Manufacturing options
The right process for your COB LED cooling requirement
We select the optimal process based on thermal performance targets, volume, and cost. Each route is designed to support practical OEM production requirements.
| Process | Best suited for | Key capability |
|---|---|---|
| Cold forged heat sinks | LED applications requiring high-density pin fins | Aspect ratios up to 35:1 with no draft angle |
| Skived fin heat sinks | High-power COB modules with demanding surface-area requirements | Maximum surface area where extrusion fin density is insufficient |
| Extruded aluminum heat sinks | Medium-to-high volume programs | Cost-effective production with CNC machining, drilling, and anodizing |
| Heat pipe and bonded fin assemblies | Applications where air cooling alone is limited | Spreads concentrated heat across a larger cooling area |
Available materials include aluminum 6061/6063 and copper C1100.
Surface finishes: anodizing, nickel plating, and passivation.
