After the Winter Olympics,
The Gangneung Curling Centre, Reborn as a Year-Round Ice Sports Destination
- This project is a case study in which a total of 92 units of the SUFA-A 1.2kW product, featuring a 5700K color temperature and a high color rendering of 90 Ra, were installed. The SUFA-A product is a remote driver type, and the external converters were installed on the structure along with the product. To address the frequent maintenance of the metal halide products, the previous lighting was installed on 12 motorized lift structures, and with the replacement to the SUFA-A product, GigaTera lighting was installed on only 10 of those structures.
To efficiently install the SUFA-A product on the motorized lift structures, separate custom brackets were fabricated. Designed to be attached to the lower part of the installation structure, the bracket design made it easier to carry out the product installation and aiming work.
The lighting standard for an Olympic stadium is based on vertical illuminance. The standard required by OBS was a minimum of 2,000 lx for the SSM (Super Slow Motion) cameras. The GigaTera SUFA-A lighting not only met all of OBS's requirements, but the vertical illuminance within the arena is actually being measured at a value higher than the original design.
As part of a test event, the "2017 VoIP Defender World Junior Curling Championships" was held at this venue for 11 days starting from February 16th. At this championship, the Korean men's junior team achieved the splendid feat of winning the world championship for the first time in Korean curling history by defeating the U.S. team. The Gangneung Curling Centre became the first of the 2018 PyeongChang Winter Olympics venues to have its entire stadium lighting installed with LEDs. After the project's completion, the structural feature of the SUFA-A 1.2kW product, being composed of two 600W modules, was evaluated by the installation company as having served as various advantages in carrying out this project.
"The Olympic Broadcasting System (OBS), which oversees the broadcast, specifies a minimum illuminance of 2,000 lx in the arena for the super slow-motion cameras. However, to meet this illuminance with conventional metal halide lighting, the heat generation is immense. It affects the ice quality. That's why we replaced all the stadium lighting with LEDs." - From an interview with an official.
- Impact and Value
-
• Minimized heat generation with excellent thermal management technologyDownload Case Study
• Improved illuminance compared to previous lighting • Excellent energy saving rate
• No flicker during Super Slow Motion broadcasts • Enabled for UHD ultra-high-definition broadcasting
• Improved 90Ra Color Rendering Index provides colors closer to natural light for players, spectators, and viewers
• Instant on/off of the lighting (no warm-up time required)
• Over 20 times the product lifespan compared to traditional lighting
