Custom LED Profiles

Extruded profiles for LED linear, strip and modular luminaires – diffusers, housings and covers designed around your LED board and optics.

What we supply

An LED profile has to satisfy three things at once: it must diffuse or shape the light, it must hold the LED board and optics in position, and it must survive the heat the board produces. Getting all three right is a section design problem, which is why LED profiles are almost always custom.

We work from your LED layout – pitch, board width, drive current and target beam – to design the section, choose between PC and PMMA, and set wall thickness and surface finish so the finished luminaire looks and measures the way you specified.

AssemblyClip, slide-in or screw-fix features extruded into the section

Options we build into the profile

  • Diffuser and housing combined in one co-extruded profile
  • Opal diffusion that hides LED pitch at a defined transmittance
  • Prismatic inner surface for controlled beam spread
  • Clip geometry for tool-free assembly
  • Flame-retardant and UV-stabilised grades on request
  • Length cutting, drilling and end-cap preparation

Frequently Asked Questions

By combining the right diffusion surface – frosted, opal or prismatic – with the right transmittance and the right distance between the LED board and the diffuser wall. We set all three together, then confirm on a prototype.
Yes. Co-extrusion lets us run an opaque housing zone and a clear or diffusing zone in the same profile, which removes an assembly step.
It helps. Board width, LED pitch and drive current tell us the heat load and the diffusion distance, which drives material choice and wall thickness.
