Product Overview

LED Light Covers Overview

An LED light cover is the visible outer element of a fixture — it protects the light engine, sets the appearance and, in most designs, does the optical work as well. We extrude covers in polycarbonate and PMMA to the geometry of your housing, including snap-in edges, end details and co-extruded opaque trims. Covers can be purely protective, purely optical, or both.

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

A cover protects and finishes the fixture; a diffuser is chosen for its optical behaviour. Many covers do both jobs at once.
Yes. Two-colour extrusion produces a clear or opal body with an opaque edge or reflector in one profile.
Protective film is standard on gloss and clear surfaces, and packing can be specified to your requirement.
