Match that: A new innovative lighting scheme to be introduced

30 November 2011 -

Total lighting magazine discovers how the city of Lima confirmed the renovation of the Peru National Stadium among the wants was for an innovative lighting scheme to be introduced.

As such a prominent build, the foremost wish was for it to be an iconic structure with a recognisable design in keeping with the mood and passion present at any football match. The creative team consisted of Claudia Paz of CAM; Cinimod Studio; and David Castañeda of Traxon. These masterminds each brought a fundamental element to the concept of the building’s interactive frontage.

Drawing on inspiration from the fast-paced changes in mood ever-present at a game, the team brought together pioneering technologies and lighting layouts to lace the facade with a mix of dancing LEDs. The scheme acts as a mirror, reflecting the mood of the audience as the fans collectively flow through emotions of excitement, boredom, disappointment and celebration; to mesmerise passersby.

Paz and Castañeda constructed onsite mock-ups, having undertaken a series of design studies, which were used to prove the merit of the system to the client. Once the system was agreed, the team was given 100 days to complete the implementation, in order to meet the Presidential inauguration of the stadium. The tight time constraints meant that all hands  were needed on deck with Traxon producing customised fixtures, and E:Cue developing the mapping and content. Meanwhile Cinimod tested hardware solutions and software algorithms as they were made.

The main obstacle for Cinimod during the project was developing a bespoke, reliable solution to deliver the ambitious scheme effortlessly. This blockade was broken down by the utilisation of a transfer of technologies from related industries, which enabled the company to create a cutting-edge mood analysis system for the stadium project.

Incorporated within the scheme is a network of customised sound level meters, which are placed along the roof line of the stadium to create a dynamic map of the crowd’s noise levels. This data is processed by Cinimod’s hardware and software located in the main communications room of the stadium.

Also developed specifically for the project was the company’s mood analysis software, used to process the sound level data in real-time, performing a series of comparative mathematical calculations and analysis by self-calibrating algorithms. The output from the software is a ‘mood state’ that summarises the collective mood of the crowd.  This ingenious software runs perpetually, constantly evaluating the mood.  It communicates the determined mood state to the E:Cue lighting controller, which then sends the relevant DMX control signal to the light fixtures…
