Reactive Lighting Walls and Pixel Mapping: The Basics of Addressable LED Installations

A Wall Made of Light

Addressable LEDs let every light in a strip, tile or panel be controlled individually. Arranged on a wall, ceiling or sculpture, they can show patterns, text or movement, and respond to sound, touch or people.

How It Works

Under the surface, an addressable installation has a few moving parts that we handle on lighting installations.

  • LED pixels — strips, tiles or modules, each with its own address
  • Controller — converts a computer feed into signals for the lights
  • Network protocols — Art-Net or sACN carrying lighting data over Ethernet
  • Pixel mapping — telling the software where each pixel physically sits
  • Power distribution — supplying enough current along the whole run

Power and Data Limits

Long strips lose brightness and colour accuracy if powered from one end, so power is usually injected at several points. Data lines have limits as well, and big installations are split into zones with separate controllers.

Heat is the other limit. Bright white across a large area draws a lot of power and needs proper ventilation.

Plan the Content With the Hardware

The resolution of the wall decides what content can look good, so design for the real pixel count. Agencies can brief us through our partnership service with the creative idea, and we will confirm what the hardware can honestly deliver.
