Typical applications

Application Profile function Key design inputs

Application	Profile function	Key design inputs
Automated production-line lighting	Fixture body, mounting rail or protective channel	Fixture length, mounting interface, cable route
LED strip and linear lighting	LED channel, diffuser seat and heat-spreading body	PCB width, diffuser geometry, thermal load
Machine-vision illumination	Rigid housing and sensor-light alignment	Optical position, vibration, access for service
Cabinet and display lighting	Low-profile recessed or surface-mounted channel	Installation space, appearance, finish

Design around the complete lighting assembly

The extrusion should be reviewed together with the LED board, diffuser, end caps, wiring, fasteners and mounting method. Critical interfaces may include PCB grooves, lens seats, screw ports and locating faces. Adequate tool access helps simplify assembly and maintenance.

Thermal and mechanical considerations

Aluminum can spread heat from LED assemblies, but the required cross section depends on power, duty cycle, ambient temperature and airflow. Thermal performance should be confirmed by the buyer’s design analysis and product testing. For automated equipment, section stiffness, joint design and vibration should also be reviewed.

Extrusion, machining and finishing

After extrusion, profiles can be cut, drilled, tapped and CNC machined for connectors, sensors or mounting brackets. Anodizing provides a clean technical surface, while powder coating can match equipment or architectural color requirements. Cosmetic surfaces and protected areas should be identified on the drawing.

Frequently Asked Questions

Can one extrusion integrate mounting and cable features?

Yes, a custom cross section can include channels, locating faces and screw ports when the geometry is suitable for extrusion and the interfaces are defined in the drawing.

Which finish is suitable for lighting profiles?

Anodizing and powder coating are common options. The correct choice depends on appearance, environment, dimensional interfaces and the buyer’s performance requirements.

What should be sent for an engineering review?

Send the profile drawing, assembly interfaces, alloy, finish, tolerances, cut lengths, quantities and any machining details.

Send your lighting profile drawing for an engineering review and quotation.
