LED high bay housing
A high bay housing is both the body of the luminaire and its heat sink. The fin field has to be complete and even for thermal performance, the board seat flat for good thermal contact, and the sealing face clean for the gasket.
We cast high bay housings on our larger HPDC machines and supply them as cast or coated through our finishing partner. The coated high bay housing in our gallery is one of these parts.
Process, alloys and indicative ranges
| Process | HPDC, larger machines in our 280 to 1,250 t range |
|---|---|
| Typical fin thickness | 1.5 to 3 mm at the tip, indicative |
| Alloys | ADC12, LM6 |
| Supplied | As cast, machined at seats and holes, or coated |
Ranges are indicative for this kind of part. We confirm process, machine, alloy and tolerances for your design at drawing review.
Critical features and how we check them
| Flatness of the LED board seat | Surface plate and feeler check in house; CMM through a partner when specified |
|---|---|
| Sealing face condition | Visual inspection in house, at every stage |
| Fin completeness | Visual inspection in house, at every stage |
| Coating adhesion and thickness | Reported by the coating partner with the batch |
Machining and finishing options
- Facing of the board seat where flatness requires it
- Drilling and tapping for drivers and brackets
- Powder coating through a partner
Questions that sharpen your quote
