Peru's stadium facade lighting responds to football fever

Peru's National Stadium's interactive LED lighting system captures the audio levels of the stadium crowd and depicts it visually on a dynamic facade.

Cinimod Studio, a London, UK-based architecture and lighting design firm, has delivered the interactive lighting control system for Peru National Stadium in Lima.

The system gathers the crowd’s noise levels in real-time and translates the audible signal into a visual map that is depicted on the facade’s lighting display.

Cinimod Studio worked as part of an international design and delivery team including lighting designer CAM and software designer ArquiLEDS, both of Lima, Peru, e:cue lighting control company of Paderborn, Germany, and Traxon Technologies, a lighting designer based in Hong Kong.

The facade lighting begins with a network of customized microphones deployed along the stadium’s roof line. This data is then processed by Cinimod’s custom processing hardware and software located in the stadium’s main communications room.

The audible data is analyzed using mathematic calculations and self-calibrating algorithms. The software then communicates a 'mood state' to the e:cue lighting controller, which transmits the relevant DMX control signal to the lighting fixtures on the building’s facade.

The external lighting scheme is designed to integrate seamlessly within the architectural framework of the building. The majority of the lights are laid out as fans of flames that wrap upwards around the form of the structure. The facade’s patterns vary in color, speed, brightness and scale.

The software runs perpetually, constantly evaluating the mood, which varies between celebration at one end of the spectrum to disappointed at the other.

The main mood states include boring, a neutral mood; dxcitement, accompanying a surge in crowd noise and pitch; celebration, typically triggered by a goal and followed by a further rise in noise level; and disappointed, triggered by an excited state followed by a rapid decline in noise level.

The scale of the stadium facade necessitated a very large array of color- and pixel-addressable fittings. The lighting controller provides 62 universes of DMX lighting control output.

  1. While Lima's modern and chic districts of Miraflores, Barranco, and San Isidro usually steal the spotlight, there should be some words of love shared for Jesus Maria, arguably the fourth most fashionable area of the sprawling metropolis. While it is largely a middle-class residential area, it is also home to the most parks of any other community in Peru's capital, perfect for the city dweller or traveler looking for a breath of fresh air and new options in their Lima travel itinerary. A number of attractive, older architectures have been replaced with newer condominiums and private spaces, but a few are now protected by the government so that their influence may live on.
