Extrusion creates a continuous profile with a repeated cross section. That makes it well suited to linear machine lights, workstation fixtures, enclosed LED bars, and other products that share the same geometry along much of their length.
Cross-Section Design
Integrating Multiple Functions Into One Profile
The cross section can include rails for LED boards, slots for lenses or diffusers, external fins, mounting channels, screw bosses, internal cavities, cable passages, and attachment features.
Aluminum extrusions are used throughout industrial manufacturing where a consistent profile is required over long lengths.
Heat-Sink Geometry
Building Thermal Surface Area Into the Profile
Fins can be incorporated directly into an extrusion so the housing also serves as a heat sink for LED boards and electronics.
Fin spacing, orientation, wall thickness, housing mass, board contact, and installation environment all influence thermal performance.
Tubular Profiles
Enclosed Extruded Sections
Aluminum extruded tubing represents one category of closed or partially enclosed extruded geometry used across industrial products.
Lighting-specific profiles can be more specialized, incorporating dedicated LED, optical, and mounting features.
Structural Shapes
Angles and Mounting Features
Extruded profiles can also form brackets, frames, rails, and mounting structures. Industrial aluminum angles are a simple example of structural extruded geometry.
Secondary Machining
Cutting the Continuous Profile Into Finished Housings
Extruded stock normally requires additional operations such as cutting to length, drilling, milling, threading, slotting, deburring, and connector machining before it becomes a finished lighting housing.
CNC-Machined Lighting Components →Surface Finish
Anodizing Extruded Lighting Profiles
Aluminum profiles can receive anodized finishes after machining where anodizing suits the product requirements.
Aluminum anodizing is one established surface-treatment category for aluminum industrial components.
