Product Overview

LED Tube Covers Overview

LED tube covers replace the glass tube of a traditional fluorescent fitting and carry the optical and protective function of the fixture. We extrude round and oval tubes, including two-colour tubes where part of the circumference is opaque to hide the light engine or act as a reflector. Wall thickness and diffusion are set to balance transmission with the appearance you want when the fitting is off.

Manufacturing Process

From drawing to packed profile

1

Drawing

2D drawing, 3D file, sketch or an existing sample.

2

Material

PC or PMMA, single-colour or two-colour, selected for optics, impact and UV stability.

3

Tooling

In-house die design and die manufacturing.

4

Extrusion

Trial run and parameter setting on a matched extrusion line.

5

Cutting

Cut to length, mitring, notching, drilling and CNC machining.

6

Inspection

Dimensional, appearance and optical checks against the approved sample.

7

Packaging

Protective film, sleeving, cartons and pallets to your requirement.

Quality Control

How the profile is checked

Every profile is produced against an approved sample or drawing. We check incoming resin, approve the first piece, measure the profile during the run, and carry out a final appearance and dimensional inspection before packing. Optical grades are verified for transmission and diffusion consistency.
  • Incoming resin inspection and batch traceability
  • First-piece approval against the approved sample or drawing
  • In-process dimensional checks on profile width, height and wall thickness
  • Light transmission and haze measurement on optical grades
  • Appearance inspection under standard lighting conditions
  • Final random inspection before packing and palletising

FAQ

Frequently Asked Questions

Yes. Two-colour co-extrusion can make part of the circumference opaque to hide components or act as a reflector.
Diameters follow your drawing. Send the target outer diameter, wall thickness and length and we will confirm producibility.
End caps are not part of the extrusion. We can cut, drill and notch the tube to suit your assembly.
