RGB Programmable LED Channel Letters

Project Challenge

The Problem On The Table

The sign had to sit on one brand colour during trading hours and run a colour sequence in the evening, from a single installation and a single power feed.

Customer Pain Points

  • Clear acrylic shows the individual LED points, white acrylic mutes the colour
  • A colour sequence has to be decided before the controller is loaded
  • RGB draws differently from a fixed-colour LED, so the transformer has to match
Our Solution

How It Was Built

Channel letters are built with either translucent clear or white acrylic on the face, with waterproof RGB LED mounted on a PVC, stainless or aluminium back plate. A programme controller is supplied, either pre-loaded or carrying a colour change sequence specified at the time of order.

Manufacturing Process

Four Stages On The Floor

Face choice

Clear acrylic for saturated colour with visible points, white for an even face with muted colour.

LED mounting

Waterproof RGB LED fixed to the back plate so the whole face is covered evenly.

Controller

Supplied with the letters, pre-loaded or programmed to the customer's sequence.

Power

Transformer supplied; the mains feed to it is planned by the installer.

Supply Chain And Quality Control

What Happens Before It Ships

Joints are dressed before finishing, illuminated builds are wired and lit before the back closes, and polished and acrylic faces keep their protective film for the whole journey. Formal QC documentation is TBC and is not claimed here.
