Product Performance and Technical Features
Specifically developed by Griven for this installation, the GRAPH-i-PIX RGBW custom LED modules are fitted with a bespoke semi-opaline diffusing front screen: "Gri-dex". This diffuser—made of fire-resistant, UV-stable, and anti-yellowing polycarbonate—was engineered exclusively for Griven to ensure exceptionally smooth colour transitions and uniform visual output. Bespoke beam angles and a special finishing enhance light reflection across the anodised aluminium cylindrical elements separating each LED bar, reinforcing the façade’s architectural rhythm.
With an IP66 protection rating and integrated thermal protection, these modules are fully resin-encapsulated to ensure maximum resistance to weathering while providing effective heat dissipation. They deliver stable output in terms of both colour consistency and saturation, enabling the luminous intensity of the multimedia façade to be modulated in response to natural light conditions throughout the day and night.
In line with the essential and rational design principles defined by the project’s architectural studio, all power and control cabling is fully concealed, and each LED bar is equipped with a quick-connect system to ensure maximum protection and ease of replacement. The ultra-slim black (RAL 9005 textured) profile integrates discreetly within the façade, delivering a versatile direct-view lighting solution capable of producing complex pixel-mapped content and high-impact abstract visual compositions.
Available in configurations with either seven or eight individually addressable pixels, the RGB+W 4000K version ensures high-quality white light output and flicker-free operation at any dimming level. The bespoke engineering of the modules enables clear daytime legibility while maintaining a refined visual presence at night, meeting both aesthetic and energy-performance requirements without compromising colour richness or operational flexibility.
We are extremely proud to have contributed to this challenging project through the development of a groundbreaking illumination system. We would like to express our sincere gratitude to all the people, organisations, and companies whose expertise, commitment, and collaboration made the successful completion of this extraordinary architectural achievement possible. Particular thanks go to our commercial and technical teams, whose skills, dedication, and professional excellence were instrumental in bringing this ambitious vision to life.
