When it comes to digital pixel lighting, the controller is the heart of the system. The right pixel controller ensures reliable data delivery, smooth animations, accurate colour control, and scalability — whether you’re installing a small feature or a large architectural display.
At PixNet Control, pixel control is our speciality. We offer a wide range of professional pixel controllers and control solutions, designed to support everything from simple SPI-driven installations to complex networked systems using Art-Net, sACN, and DMX.
This guide explores the different types of pixel controllers we offer, and how they fit into real-world lighting applications.
What Is a Pixel Controller?
A pixel controller is a device that converts control data — such as DMX, Art-Net, sACN, or internal sequences — into the digital signals required to drive individually addressable LED pixels. These signals are typically SPI-based protocols used by popular pixel chipsets found in LED tape, modules, nodes, bars, and Neon Flex.
Choosing the right controller depends on:
-
Project size
-
Control protocol
-
Pixel type and quantity
-
Required reliability and scalability
Networked Pixel Controllers (Art-Net & sACN)
For medium to large installations, networked pixel controllers provide maximum flexibility and scalability.
These controllers receive Art-Net or sACN over Ethernet and output pixel data across multiple ports, allowing thousands of pixels to be controlled from lighting desks, media servers, or show control systems.
Typical applications include:
-
Architectural façades
-
Stage and theatre lighting
-
Clubs and venues
-
Festivals and outdoor events
-
Pixel-mapped video effects
Networked controllers are ideal where real-time control, synchronisation, and expansion are required.
SPI Pixel Controllers
SPI pixel controllers are commonly used for installations where pixel data is generated internally or triggered via simple commands rather than live DMX control.
These controllers are well suited to:
-
Static or looping effects
-
Trigger-based lighting
-
Embedded or interactive installations
-
Architectural features with predefined animations
SPI controllers provide direct, reliable control over addressable LED pixels and are often used where simplicity, stability, and low latency are key.
DMX-Based Pixel Control Solutions
In environments where DMX is the preferred control protocol, pixel control solutions allow DMX data to be translated into pixel-level control.
This approach is commonly used in:
-
Theatres
-
Touring productions
-
Permanent venue installations
-
Hybrid systems combining traditional fixtures and pixel lighting
DMX-based pixel control bridges the gap between conventional lighting systems and modern addressable pixel products.
Standalone & Embedded Pixel Controllers
For smaller projects or self-contained installations, standalone pixel controllers offer a compact and efficient solution.
These controllers can run pre-programmed effects without external control, making them ideal for:
-
Retail displays
-
Signage
-
Feature lighting
-
Permanent architectural accents
Standalone controllers reduce system complexity while maintaining professional results.
Supporting Pixel Control Accessories
In addition to controllers, we offer supporting signal and system accessories designed to improve performance and reliability, including:
-
Signal buffers and extenders
-
Data splitters
-
Protocol converters
-
Power and data management solutions
These components are essential in larger systems where cable lengths, pixel counts, or environmental conditions could otherwise affect performance.
Choosing the Right Pixel Control Solution
Every project is different, which is why we focus on offering solutions rather than just products. Whether you’re controlling a short run of LED pixel tape or a multi-universe architectural installation, selecting the right controller ensures:
-
Stable data transmission
-
Accurate colour reproduction
-
Smooth animations
-
Long-term system reliability
Our team is always available to help match the right controller to your pixel products, control system, and installation environment.
Pixel Control Is Our Speciality
With a comprehensive range of pixel controllers, protocols, and accessories, PixNet Control supports digital lighting projects of all sizes — from simple installations to complex, large-scale systems.
If you’re planning a pixel lighting project and need guidance on controller selection, integration, or system design, our team is ready to help.
