LED High Bay Skived Heat Sink
Circular skived heat sink with radial fins for COB light sources in high bay, flood and stage luminaires.
Tolerances and finish confirmed against drawing; production follows sample approval.
Specifications
| Alloy | 6063-T5 |
|---|---|

| Outer diameter | Custom to housing ID |
| Fin layout | Radial skived fins |
| Surface finish | Anodizing + sealing |
Luminaire heat sinks are usually round, with fins radiating from the centre. Inside the fixture this creates a chimney effect: hot air rises through the channels and natural convection removes most of the heat.
Design points
The centre pad needs enough thickness for the COB holder and lens. Fin height follows wattage and mounting angle. For outdoor fixtures we recommend anodizing plus sealing so damp air does not leave white marks.
Typical range
Most requests fall between 50 W and 200 W. Customers give us the inner diameter of the housing and we work back to fin count and outer diameter so the sink drops in without touching the shell.
Process notes
Round billet cutting, radial skiving, centre pad milling, drilling, deburring, anodizing, assembly dimension sampling.
Applications
LED high bay lights, floodlights, area lights, stage lighting, grow lights.
