A purpose-built environment for immersive research and next-generation learning
Engineering an immersive lighting experience
The University of Adelaide’s Nexus AI/VR Hub was conceived as an immersive learning environment where virtual reality, artificial intelligence and digital visualisation converge. At the heart of the space sits a large-format LED display, but the challenge extended well beyond the video wall. The ceiling itself needed to become part of the experience.
The design brief called for two suspended illuminated grids that would appear as continuous lines of light floating above the VR environment. The system needed to integrate seamlessly with the suspended services grid while delivering dynamic RGBW lighting under DALI control, allowing the ceiling to respond to changing virtual environments and create a fully immersive space.
From an engineering perspective, the project was anything but conventional.
Turning a Concept into Reality
The original brief specified an illuminated grid closely matching the width of the supporting trunking, minimising profile depth and eliminating visible butt joints wherever the linear sections intersected. The lighting also needed to provide RGB and tuneable white capability, allowing both atmospheric coloured scenes and functional white light from the one installation.
While the visual outcome appeared simple, achieving it required Digilin to develop a completely bespoke solution.
Rather than assembling standard linear luminaires into a grid, Digilin engineered a purpose-built version of its Space 35 linear platform, incorporating custom fabricated L, T and X junctions that maintained perfectly continuous illuminated lines throughout the entire structure.
Solving the Intersection Challenge
The greatest technical challenge was the lighting intersections. Every crossover required the LEDs to continue uninterrupted in four directions while maintaining consistent brightness, colour mixing and optical performance. Simply joining separate luminaires would have created visible dark spots, inconsistent diffusion and complicated installation.
Digilin designed custom PCB layouts that allowed the RGBW circuitry to flow seamlessly through every intersection. This demands a high level of level of precision, with each junction individually assembled, soldered and tested to ensure colour consistency and uninterrupted illumination before the diffuser was installed. Equally important was the optical design. Careful calculations were undertaken to determine the ideal LED spacing and mounting depth so adjacent beams blended together before reaching the diffuser, producing continuous lines of light without visible segmentation.
Designing for Installation
While the finished installation appears effortless, considerable engineering was invested in making the system practical to manufacture, transport and install.
Rather than delivering a single oversized structure, each grid was factory-built as four fully wired assembly groups, complete with profiles, junctions and RGBW electronics. This approach dramatically simplified handling while maintaining factory quality control. Each module included dedicated wiring tails and independent control, allowing installers to assemble the completed grid onsite using concealed interlocking joiner plates.
To further reduce installation risk, Digilin produced detailed shop drawings covering grid geometry, electrical schematics, mounting layouts and control architecture, together with a dedicated unpacking and installation guide specific to the project. The documentation even specified laser alignment of mounting clips to ensure the finished grid remained perfectly square and that concealed joiners produced seamless transitions without light leaks.
This level of preparation transformed what could have been a highly complex onsite build into a structured installation process.
Intelligent Control
The complete lighting system operates on Digilin’s constant-voltage RGBW platform with DALI control, allowing the illuminated ceiling to synchronise with the immersive digital content throughout the AI/VR Hub.
Multiple power supplies and repeaters were strategically distributed across the assembly groups to simplify wiring while maintaining uniform performance across the entire installation. The architecture was also designed with future flexibility in mind, allowing migration to DMX control through a straightforward change of the primary control device should the University’s requirements evolve.
Hidden Complexity
Perhaps the greatest success of the Nexus AI/VR Hub is that none of this engineering is immediately visible. Visitors entering the space simply experience an elegant illuminated ceiling that complements the massive LED display and enhances the immersive environment. Behind that simplicity lies months of collaboration between designers, engineers and manufacturing specialists, solving challenges in electronics, optics, mechanics, installation and control. Every custom junction, concealed connector, factory-tested assembly and detailed installation procedure contributed to a lighting system that performs as one continuous architectural element.
The Nexus AI/VR Hub demonstrates what can be achieved when lighting is considered as an integral part of the architecture rather than an afterthought. By combining Australian design, precision manufacturing and innovative engineering, Digilin delivered a bespoke linear lighting solution that transforms a functional ceiling into an immersive architectural feature—one that supports learning, inspires creativity and becomes part of the digital experience itself.
