Turning the stadium into an entertainment space by controlling 354 floodlights and displaying images

The new stadium has two stories below and six stories above ground, with one of the world's largest retractable roofs (approximately 166 meters across) and a capacity of around 35,000 spectators. The number of seats used by visiting fans on the side of the field next to third base has been reduced, and TOWER 11, a five-story complex with a hotel and hot springs, has been built above the left outfield seating. The south side of the stadium is a huge glass wall, which at its highest point rises to around 70 meters. As well as guaranteeing sunlight, this functions to link the inside of the stadium with the external space. 226 2 kW-equivalent and 128 1 kW-equivalent LED floodlights are installed at the top of this glass wall and on fixed sections of the roof. To prevent these floodlights from adversely affecting play and dazzling the players on the field, they feature restricted light distribution that narrows the beam of light being emitted from the light source, and by dispersing the floodlights’ directionality, there is less overlap and reduced glare for players and spectators when they look up. In response to the action during a game, be it a home run or a victory for one of the teams, DMX control combines brightness adjustment (0–100% dimming) and instantaneous strobing effects to realize a show that is a fusion of light, video, and sound. What makes this possible are Panasonic’s “KAIROS” IT/IP platform and integrated management system “S-CMS”. “KAIROS” processes multiple video signals, while “S-CMS” provides integrated control of lighting, video, and audio to deliver content from any viewing angle and at any resolution, on large-scale screens and on approximately 600 digital signage displays installed around the stadium.

A distinctive feature of the new stadium is its diversity of spectating environments. One of these is the “Panasonic CLUB LOUNGE”, which is located opposite third base near the dugout. Here, visitors can experience Panasonic products and services while enjoying gourmet cuisine. Spectating from the same viewpoint as the players also gives visitors a sense of being directly involved in the game. In a relaxing space with wooden design features and low lighting, Panasonic’s downlight projector “BioSHADOW” recreates the spectacle of sunlight filtering through the trees, while the spotlight-type nanoe™ X Generator and the “Ziaino” sodium hypochlorite air disinfector and deodorizer create an environment with comfortable air quality. The lounge provides an unprecedented spectating experience, with theatrical lighting and the latest beauty, health, and AV products.
