China has once again ignited the flame of passion and dreams, and the world's eagerly awaited Beijing Winter Olympics will open on February 4, 2022 (tonight).
"Water Cube" transformed into "Ice Cube", "100 meters, minute level" accurate weather forecast, the national speed skating hall in the world's largest span of single-layer two-way orthogonal saddle-shaped cable net roof, 5G signal coverage of all venues, 8K competition screen real-time transmission... The Winter Olympics of Science and Technology is the main feature of the Beijing 2022 Winter Olympic and Paralympic Winter Games, a stage that reflects the comprehensive national strength of the mainland, and a stage for achieving high-level scientific and technological self-reliance and self-improvement.
Dunhuang flew in the sky, and the ribbons fluttered. When night falls, under the illumination of the "light" of science and technology, the Shougang Ski Jump at the Beijing 2022 Winter Olympics is like a flying streamer, gently, fluttering, soaring...
Beijing Winter Olympics, this ice and snow sports event is about to kick off. Whether it is to ensure the smooth progress of the event, or to present high-definition broadcast to the world, or to ensure the safety and performance of athletes, as well as the visual effects of the audience, it is inseparable from scientific and technological lighting. The lighting needs of outdoor snow projects and indoor ice projects are different in the application of science and technology.
Dream Light Shaping "Snow Flying"
On the evening of January 6, 2022, as one of the venues of the Beijing 2022 Winter Olympic and Paralympic Winter Games, the Shougang Ski Jumping Platform "Snow Flying Sky" is undergoing lighting effect debugging. As the music slowly sounds, the effects of lighting, mood lights, spotlights and neon lights are on display. From the front of the big jump platform, the changing lights and shadows that move with the sound, the dazzling Olympic rings, the bright pillars of light shooting into the sky, and the flickering and jumping light spots are like stepping into the mysterious world of the Na'vi in the movie "Avatar".
Qunming Lake Center to see the Shougang Ski Jump
"Traditional lighting design mainly focuses on the carrier, that is, the object being photographed, and we pay more attention to people." As the person in charge of the lighting design of the Shougang Competition area of the Winter Olympic Games, Zhang Xin, director of the China Lighting Society and long-term associate professor of the School of Architecture of Tsinghua University, also shoulders the work of lighting design and chongli lighting coordination in Yanqing.
In his view, unlike ordinary lighting design, the lighting design of the Beijing Winter Olympic Games area fully considers the post-game utilization and urban development, and pays more attention to the sustainable design requirements.
The shape design of the ski jump "Snow Flying Sky" comes from Dunhuang's Flying Streamer. In order to make the "streamer" truly present a flowing and flexible feeling, Zhang Xin has made careful planning in lighting planning and design.
"In terms of lighting planning, the landscape lighting of the ski jump should be dominant, it is the 'emitter' of light, and the surrounding oxygen plants and cooling towers play the 'receiver' of light by reducing the brightness to the distance and strictly controlling the light color (4500K). In terms of design, the three-layer streamer increases the brightness layer by layer from bottom to top, showing the upward momentum, metaphorically the existence of a moon-like natural light source at high altitude. Zhang Xin said.
Since the audience is looking up when watching the ski jump, this requires that the lights of the "streamers" must not only be facing upwards, but also eliminate glare. To this end, Zhang Xin's team decided to "hide" the lamp into the "streamer".
However, it is not enough to "hide" it. "Because the width, tilt angle and height of the 'streamer' are continuously variable, it is necessary not only to ensure that the entire light does not interfere with the athletes' competition, but also to meet the multi-perspective viewing needs of broadcasters, referees and live audiences." Zhang Xin said.
For him, the lighting design of the "streamer" is "a hammer deal", "the most important thing about lighting is to adjust the lamp, because once the light is loaded into the 'streamer', there is no chance to adjust it, we must adjust the lamp to the most reasonable angle on the ground."
In order to ensure the success of one time, Zhang Xin's team not only conducted in-depth research on the installation position, method, angle, color temperature, power, and depth of the shading cylinder of the lamp, but also specially produced two "streamer" foot gauge models. After repeated experiments, they finally determined the final parameters. Standing at the foot of the "streamer" and watching the "exquisitely crafted" lamps and lanterns slowly rise and return to their positions after more than a year, Zhang Xin felt very pleased.
The Light of Wisdom Presents "Snow Ruyi"
Dai Baolin, executive director of the China Lighting Society and chairman of Halsey Technology Group, who participated in the lighting design of the "Xue Ruyi" lighting of the National Ski Jumping Center, said, "We have integrated the latest technology into the construction of the Beijing Winter Olympics project and created a new lighting mode for the 'Smart Winter Olympics' series of projects. ”
National Ski Jumping Center "Snow Ruyi"
In the early stage of the implementation of the "Xue Ruyi" project, Halsey specially set up a design, technical support and implementation team to conduct a detailed survey of the site. The team found that the overall length of "Snow Ruyi" was only 136.2 meters, but the height difference reached 135 meters, the maximum slope angle exceeded 60 degrees, and the temperature difference between day and night in the site was very large.
"This presents unprecedented challenges to design capabilities, luminaire quality and construction capabilities." Dai Baolin said, "In order to ensure the perfect display of the ski jumping project and ensure the later operation, the designers all adopt customized waterproof and temperature-resistant products in the arena, and through multi-type and multi-functional lamp installation, the 'Snow Ruyi' is perfectly presented to the public at multiple levels and angles." ”
"Snow Ruyi" overall lighting to respect the building, light color is appropriate, light intensity moderate, green economy, continuous operation as the principle, in the brightness relationship processing, so that the overall light color, the top and the slide two wings of the lighting effect complement each other; in the lighting performance method, the peak façade uses indoor lighting and a small number of projectors to present the Olympic symbol on the glass, the two wings of the use of white light gradient, slow flow of expression, like the halo flowing on top of the "Snow Ruyi"; in the contour image design, Through the combination of projection and façade contour, the "Snow Ruyi" contour display effect is strengthened, further highlighting its overall shape.
"The final perfect presentation of the 'Xue Ruyi' project represents a very high level of innovative technology for lighting applications in China." Dai Baolin said that Halsay has been engaged in the lighting industry for more than 20 years and has undertaken many large-scale conferences in smart lighting projects. In the construction of the Beijing Winter Olympics series of projects, Halsey also fully demonstrated the "light of wisdom innovation", with its self-developed algorithms and virtual simulation technology, to achieve wide color gamut, full color temperature, multi-channel intelligent adjustment, so that the lighting effect of each venue successfully passed the OBS (Olympic Broadcasting Service Company), IBSF (International Snowmobile Association), FIL (International Bobsleigh Association) site certification.
LEDs light up the biathlon field
"The lighting system of the National Biathlon Center is currently the world's largest competition field that uses all LED lighting, and it is also a difficult lighting project to implement." Yao Mengming, specially invited vice president of the China Lighting Society, director of the Expert Working Committee of the China Lighting Society, and general manager of the lighting design and application department of Signify Greater China, introduced, "The snow project requires a uniform lighting arrangement and meets the illumination requirements of the project, and the lighting cannot change the surface form of the slope, and the terrain and nearby obstacles should be clearly displayed for the athletes." At the same time, it is also necessary to solve the problem of strobe of ultra-high-speed cameras during 4K HDTV broadcasting, and the reflective image generated by wet ice on the field. ”
In Yao Mengming's view, "the lighting system of the stadium should be integrated with natural conditions such as mountains and trees, and fully consider the height, slope, turning and other characteristics of the competition venue." Therefore, the position of the lamp should comprehensively consider the relationship with the shape of the track and the position of the camera, while the lighting control system needs to solve a series of problems such as long-distance signal transmission, system synchronization, and anti-interference. ”
Lighting effects for biathlon centers
The core area of the National Biathlon Center is large, and all high-power lamp poles are used and illuminated with high-power lamps; while the track area is mostly used for medium-height poles with medium- and high-power lamps due to irregular shapes and limited widths.
The light of technology shows the snow in the forest
These advanced lighting concepts are also vividly reflected in the design of the street lighting system in Yanqing Division.
Zhang Xin believes that in the Yanqing Competition Area, lighting planning should be based on the principle of "protecting ecology, practicality is beauty", taking the solution of functional lighting as the primary task, controlling the excessive visualization of the night scene of the building, using functional lighting to present the grand scene of the mountain forest venue, and "weakly intervening" in the natural ecology.
In order to uphold the "weak intervention" of the venue to the natural environment, the team designed the mountain "arbor" street lamp family in the competition end area and the race end area of Yanqing Division, inspired by the vegetation characteristics of haituo mountain area, and the standardized modules of various functions can be flexibly combined according to the actual needs of the venue.
In addition, in order to take into account the lighting and landscape effects, they also specially made a garden light system in Yanqing Winter Olympic Village. The lower part of the lamp adopts a custom imitation paper glass lampshade to ensure the functional illumination and environmental lighting of the road with soft diffuse light; the upper part of the lamp uses a flood light, which can flexibly adjust the brightness and illumination direction, provide vertical illumination for the public activity area centered on trees, illuminate trees and building corners, and provide visual positioning for athletes.
For the night lighting in the core area of the Chongli Winter Olympics, Zhang Xin believes that the principle of "functional lighting, attaching importance to sustainability, paying attention to overall control, and advocating ecological night scenes" should be used to show the overall night scenery of "Winter Olympic Town, Ski Resort".
Yanqing division is a metaphor for the custom lighting system of cold land trees
On January 17, President Xi Jinping pointed out in his speech at the 2022 World Economic Forum video conference that China is confident of dedicating a simple, safe and wonderful Olympic event to the world. Zhang Xin said, "General Secretary Xi Jinping's speech is inspiring. The lighting technology of the Winter Olympic and Paralympic Winter Games fully reflects the concept of low-carbon, ecological and sustainable development. As a member of the China Lighting Society, Dai Baolin said, "We will show the green Winter Olympics and the Winter Olympics of science and technology to the world through the way of 'light + culture + technology', pass on the concept of low-carbon, ecological and sustainable development to everyone, use the 'wisdom brain' to serve the national construction, and work with the Winter Olympics to the future and the motherland to 'bright'." ”
Landscape lighting appreciation of the City of The Two Olympics
According to the relevant person in charge of the office of the urban operation and environmental protection group, the landscape layout adheres to frugality, the landscape sketches and lighting use LED energy-saving light sources, and the use of green environmental protection materials such as colored organic coverings enrich the winter colors of the city, so that the garden waste can glow with the charm of art.
Tiananmen Square "Wonderful Winter Olympics" theme flower beds
Tiananmen Square arranged the "Wonderful Winter Olympics" theme flower beds. The flower bed is 17 meters high, with a Chinese knot as the main scene, combined with the emblem of the Winter Olympic Games and ice and snow elements, to convey good wishes for the Beijing Winter Olympic Games. It is reported that during the Winter Paralympic Games, the emblem of the Beijing Winter Olympic Games in the Flower Bed Center will be replaced by the emblem of the Beijing Winter Paralympic Games.
