150 W High Bay Luminaire Heat Sink
Circular skived heat sink sized from the housing inner diameter, with radial fins for a 150 W COB.
Requirement
The fixture housing inner diameter is fixed. The previous sink was oversized and scraped the shell after assembly, and temperatures near the light source ran high. They needed a sink for a 150 W COB within the same envelope, concentric with the housing.
Our approach
Outer diameter and fin count were derived from the inner diameter, with radial fins and a thickened centre pad for the COB holder. The mounting face is concentricity-controlled to avoid scraping. Anodizing plus sealing suits damp outdoor conditions.
Delivery and inspection
Five samples for housing fit-up, then production with outer diameter and concentricity checked piece by piece.
Project summary
Fit-up is clean and light source temperatures meet the customer test plan. The section is now standard, with only fin height changed for other wattages.
