The L’Illa Diagonal shopping center in Barcelona has taken a significant step toward innovation in lighting design with the installation of a 1,100 sqm immersive ceiling. This project, created by Lumalia Studio, transforms the space into a living surface of light, offering visitors a unique sensory experience. Digital lighting has been seamlessly integrated into the mall’s architecture, acting as an architectural system capable of evoking emotions, interacting with visitors, and creating unique experiences along the journey. This integration not only enhances the aesthetics of the space but also improves energy efficiency, contributing to the sustainability of the environment.

Stretched fabric with LED backlighting

Behind the stretch ceiling lies a digital LED lighting system that transforms the surface into a uniform light diffuser. The stretch membranes, made of PVC or coated polyester, create smooth, durable, and customizable surfaces suitable for ceilings, walls, or suspended elements. Each light point can be individually controlled, enabling dynamic scenes such as gradients, moving effects, color transitions, starry skies, or even visual projections. The translucent fabric distributes light evenly without visible hotspots, while LEDs ensure low energy consumption, long lifespan, and fully adjustable colors. All of this is managed through software and controllers that can be synchronized with music or environmental settings, delivering immersive and contemporary experiences.

Interactive Lighting at L’Illa Diagonal: A Ceiling That Responds to Every Movement

The immersive ceiling innovation reaches a new dimension thanks to the application designed and developed by Lumalia Studio, which transforms the ceiling into a real-time interactive canvas. Visitors can take control of the content, moving sections of the ceiling as if it were a vast canvas and “painting” shapes and patterns as they explore the space.

The application allows users to adjust speed, size, intensity, and color, offering a direct, tactile experience. Visitors can create hearts, flowers, upward and downward movements, as well as more abstract and personalized compositions. In addition, the app’s control platform includes specially designed visual content, such as fish, aurora borealis, immersive skies, abstract patterns, and custom-made compositions that allow visitors to explore light and color in a playful and emotional way.

Each creation unfolds instantly across the ceiling, turning it into a living element of architectural expression and emotion, where light is no longer passive but becomes a medium for participation and creativity for visitors of all ages.

The system transforms lighting into an active element of the space, capable of interacting with visitors and generating memorable experiences. Every user action translates into visible lighting effects, making the ceiling a dynamic canvas. Additional content such as fish, abstract patterns, and personalized compositions reinforces the playful and emotional character of the experience.

Digital lighting not only redefines the way we inhabit retail spaces, but also sets a new benchmark for future installations in the fields of lighting design and immersive experiences, showcasing the innovation and creativity that Lumalia Studio has delivered through this interactive application.
