How to control the projection of 100,000 lamps

The "Xue Ruyi" of the National Ski Jumping Center is exquisite in shape and majestic, and has become a landmark project in the Zhangjiakou Division of the Beijing Winter Olympics. In the area of ​​lighting, the National Ski Jumping Center also has several innovations
Zhongshan enjoy LED Co., Ltd. introduced that through the application of Internet of Things technology, "Xue Ruyi" lighting can provide a multi-scene intelligent lighting mode for events, which not only meets the high requirements of international sports events broadcast on the light environment, but also avoids Light pollution, effectively reducing energy consumption. "At present, the equipment has been debugged, and the company's technicians have been incorporated into the Winter Olympics support team, and will soon cooperate with the competition for venue lighting." 

The National Ski Jumping Center has adopted nearly 100,000 lamps and projection equipment such as waterproof beam lights, dyeing lights, wall washers, and flood lights. All lamps use energy-saving and environmentally friendly LED lamps. The shape of the lamps will not affect the integrity of buildings and landscapes during the day, and will not cause ultraviolet damage to green plants and the night sky at night
Each LED light has three reference colors of red, green and blue. Ordinary lights generally only show one or a few colors. The "Xue Ruyi" lighting project team uses high technology to make these three colors have 256 grayscales and mix them arbitrarily, which can generate more than 10 million colors. Colorful dynamic changing effects
How can so many colors be adjusted? It is understood that Zhangjiakou Olympic Sports Co., Ltd. innovatively adopts the combination of Internet of Things technology and multi-professional to form a number of smart lighting technologies, and installs a "smart brain" for "Xue Ruyi" lighting
The Summit area with the overall lighting effect of "Xue Ruyi". The Summit Club adopts the LED point light method to realize the presentation . High-power beam lights will also be distributed on the top of the building to form a three-dimensional intertwined dancing light with the effect of performing aerial performances
In response to the diverse needs of light environments in different scenarios such as competitions, opening and closing ceremonies, and post-match operations, the team studied the key technologies for the deep integration of IoT technology and multi-professional lighting systems, intelligent control technology for 3D lighting interpretation, and multi-lighting systems based on The key technology to realize four-dimensional linkage control on the same time axis realizes the perfect connection between night scene lighting and stage lighting, and solves the technical difficulties of professional sports lighting, lighting interpretation, intelligent control mode and TV broadcast effect for snow sports in international events
The project combines artistic rendering with media production and performance control, and uses a performance playback and playback system that integrates edge fusion, special-shape correction, real-time media editing, 3D interactive applications, and stage art equipment control, and realizes the requirements of different scenarios. Various control modes such as "Opening Ceremony Mode", "Event Mode", "Post-match Operation Weekday Mode", "Post-match Operation Festival Mode", "Post-match Operation Major Festival Mode", etc. The technological innovation of this project has reached the international leading level, and it is the first case of its application in major international sports events in China
The Science and Technology Winter Olympics are reflected in many aspects of the construction and operation of “Xue Ruyi”
In addition to the smart lighting technology, in terms of smart display, the "complex surface full-color laser display technology" developed by the "Science and Technology Winter Olympics" key project "Intelligent Presentation and Advanced Display Technology R&D and Application Demonstration in Snow Venues" led by Zhangjiakou Olympic Sports Company Enter the National Ski Jumping Center. Through the integration of high-efficiency laser light source module technology and technology, a large-scale mountain projection has been realized. The bottom stand area of ​​"Xue Ruyi" can realize a large screen display with a projection area of ​​1,000 square meters
In addition, the side of "Xue Ruyi" is also equipped with a variable-angle inclined elevator whose running angle changes with the mountain situation. This inclined elevator is specially designed and produced for the special shape and competition use of "Xue Ruyi". It is currently the fastest variable-slope elevator in the world, with a total length of 259 meters and a speed of 2.5 meters per second, which is five times the speed of the current common variable-slope elevator.
