October 22, 2007 -A three-dimensional matrix of 624 globes, each fitted with 24 LEDs, provides a compelling lighting scenario in the atrium of law firm Allen & Overy’s office building in Bishops Square, which was designed by Foster and Partners. The concept and design of the “Pixel Cloud” was developed and produced by the Jason Bruges Studio in London and Ledon.

LED globes consisting of 12 surfaces and 24 LED - 624 LED globes stretch across eight floors and open up an immense colour spectrum of 16 million colours at the headquarter of Allen & Overy

The LED light sculpture is suspended from the ceiling of the 10-storey atrium in the office building of the prestigious law firm like an oversized chandelier, its intermittently controlled dynamic changes in colour and light invoking the international reach of Allen & Overy’s world-wide network. The Pixel Cloud extends over eight floors and, with its impressive design, conjures up a striking lighting scene. 624 milky-white polycarbonate globes, each with a diameter of 120 mm, combine to form a three-dimensional network. Each of eight parallel high-gloss polished stainless steel sections supports three arms which each carry 26 globes. The globes are fitted with 24 LEDs and are individually controllable. Inside the globe, a dodecahedron-shaped flexible circuit board ensures each globe is uniformly illuminated. 8-bit resolution in the primary colours red, green and blue opens up an immense colour spectrum of 16 million colours.

The spectacular lighting solution with its diverse range of lighting moods and appearances

Every globe is individually controllable thanks to specially developed software. Real-time colour and light updates perpetually change the three-dimensional LED lighting installation’s appearance, which lends it an amazingly live effect. The server generates an extremely wide variety of modes. A sky-watching camera installed on the roof is used to transfer images of passing clouds onto the Pixel Cloud. This diverse, ever-changing LED application includes films or sequences of prepared individual images and even supports interactive involvement of web communities. Colourful animations and playback of local weather phenomena provide constantly evolving spectacular simulations in the atrium space. Jason Bruges Studio has adjusted the spacing of the Ledon globe matrix so that it matches the grid of the façade designed by Foster and Partners. The internal glass façade is transformed by changes in colour and light. One bar at a time lights up, bringing the outdoor lighting mood indoors, from top to bottom, sharing it with those working in the offices.
