Ensuring the stable operation of products in a sub-zero temperature environment becomes a test
From the countdown to the 24 solar terms to the water of the Yellow River, from the ice cube gradually breaking to the crystal clear ice and snow five rings "breaking the ice"... On the evening of February 4, the futuristic and Chinese charm of creative visual effects shocked the opening ceremony of the Beijing Winter Olympics. Throughout the opening ceremony of the Beijing Winter Olympic Games, the characteristics of "few people but not empty, ethereal and romantic" are extremely expressed. Lighting has become an important "helper" to achieve this effect.
According to reports, according to the characteristics of the structure of the bird's nest, the main lighting of the opening ceremony adopts multi-level circular lighting, the upper floor of the venue has the light that outlines the building body, and the lower floor has the light of the performance area. Lighting design makes extensive use of internal and external light translucency techniques to realize the shaping of light and shade relationships, perspective relationships, spatial relationships, etc., and form a three-dimensional multi-dimensional lighting environment.
Guangzhou Pearl River Lighting Technology Co., Ltd., a local pearl national brand enterprise from Guangzhou Panyu, escorted the on-site technical support of the Winter Olympics. At the opening ceremony of the Winter Olympics, more than 500 head-shaking cutting pattern lamps and more than 600 head-shaking dyeing lamps surrounded the top of the bird's nest to create a layered artistic light and shadow effect for the entire venue, and more than 300 480 three-in-one shaking head computer lights also created a warm effect atmosphere for the stage.

Behind the cool stage effects, the performing arts equipment needs to maintain stability in harsh environments. Hardiness is the primary problem faced by performing arts equipment during the Winter Olympics. According to the data, in 2020, the Genting Ski Park in the Zhangjiakou Racing Area measured temperatures below -40 °C. Taking ordinary lighting products as an example, the minimum temperature that only the chip can tolerate is about minus 10 ° C. Below this temperature, the lighting equipment may not function properly. In this regard, some related companies frankly said, "How to maintain the stable operation of products in a sub-zero temperature environment has become a test." ”
20 years ago, the main solution was to light the lamp and ensure the normal operation of the lighting and audio products with the heat of the bulb. This year, Pearl River Lighting has repeatedly tested and improved the cold resistance and stability of the product under extreme cold conditions in advance to ensure the provision of highly explicit, high-saturation and more stable lamp products. During the opening ceremony, on the west side of the auditorium, Guangzhou Huahui Audio Consulting Co., Ltd. provided 8 sets of L-Acoustics K2 equipment to meet the needs of sound pressure levels. The sound team has set up a thermal insulation shed at 16 power amplifier points, and adopts Internet of Things technology to monitor the temperature and humidity in the shed in real time, and monitors the status of all power amplifiers in real time through professional software.

"The acceptance standards for our products at this year's Winter Olympics are very high, especially the requirements for waterproof performance, which are completely different from the standards when we participated in the Olympic Games in 2008." Talking about the products provided by the company for the Winter Olympics this year, He Shoufeng, the relevant person in charge of Guangzhou New Stage Lighting Equipment Co., Ltd., could not help but sigh. The dimming control system for the opening ceremony of the Winter Olympic Games is provided by the new stage lights. According to He Shoufeng, at present, in addition to waterlogging, whether it is heavy rain, hail or blizzard weather, the products of new stage lighting are guaranteed to operate normally.
As one of the suppliers of outdoor waterproof performing arts lighting for the Winter Olympics, Guangzhou Gaolang Electronic Technology Co., Ltd. produced outdoor cultural tourism performing arts Leishen series LED cutting moving head lights and other products in Zhangjiakou Awards Plaza, its waterproof level reached IP 66.

"The colors seen on TV should be the same as those seen on the spot"
More refinement is another high standard for lighting and sound products. According to He Shoufeng, the projection deviation standard for stage lighting at the opening ceremony of the Winter Olympic Games is stricter than that of international standards. At the same time, the light illuminated must maintain a uniform color within the illumination range, that is, the light in part of the range cannot be dark in color and the light on the other side is light. Such a requirement is not easy to achieve in the Bird's Nest, a 258,000-square-meter mega-venue.
To this end, Guangzhou Yifeng Electric Appliance Industrial Co., Ltd. provided 1500 AECO 20 units to the opening ceremony of the Winter Olympic Games. The equipment is a high-power 1400 watt LED, set beam, pattern, dyeing and cutting as one of the four-in-one lamp, the equipment uses an innovative high color light source system, can release a high and uniform beam, showing a real and natural HIGH-definition texture, mainly to solve the opening ceremony of different scenes switch the stage of the surface light needs. The rich pattern plate and color plate are arranged according to the situational style with a variety of prisms, creating a colorful dynamic effect, giving the stage more vivid vitality, and perfectly presenting the ethereal and aesthetic texture in front of the eyes.
On the evening of February 4, the opening ceremony of the Beijing Winter Olympics was held on the night, and the National Centre for the Performing Arts, together with Beijing Radio and Television, combined with 8K ultra-high-definition technology, broadcast the opening ceremony of the Beijing 2022 Winter Olympics in 8K at the Opera House. Recently, Han Qiang, deputy director of the Media Operation Department of the Beijing Winter Olympics Organizing Committee, publicly introduced that the 2022 Beijing Winter Olympics will all use 4K ultra-high-definition signal production, fully realize UHD+ KDR production in all projects, and provide 8K public signals to rights holders for the first time, and carry out 8K production or live broadcast of opening and closing ceremonies, figure skating, short track speed skating, ski jumping, etc.
From 2K to 4K, and then to 8K, the finerness of the screen picture is getting higher and higher, and the requirements for on-site reproduction are also higher. Su Jian, the relevant person in charge of Yifeng Industry, told Nandu reporter that 8K almost requires that "the colors we see on TV and the colors we see on the scene are consistent", which requires stage lighting products to have excellent high display performance.
As one of the main suppliers of lighting equipment for the Winter Olympic Games, Guangdong Yiri Lighting Technology Co., Ltd. has a total of nearly 10,000 lighting products appearing on the opening stage of the Winter Olympic Games and on a number of events, of which there are more than 2,000 at the opening ceremony. The company's EK COLLIDER BAR IP LED full-color strobe bar and COLLIDER FC LED full-color strobe light are bright for a long time, and the pixel strobe greatly enriches the lens picture. In particular, the COLOR RANGER Q48E dyed lamp is soft in color and full, presenting a beautiful picture in front of the national audience, the entire Bird's Nest stage is ethereal, beautiful, like a fairyland, showing the Chinese introverted and implicit high-level artistic aesthetic, making people shout: "Every second is wallpaper!" ”
In the open outdoor arena, the fine embodiment of audio products is evenly distributed in sound and "no dead ends". Take the National Ski Jumping Center in Zhangjiakou As an example, the center is the first ski jumping venue in mainland China that meets international standards, and is the competition venue with the largest amount of engineering volume and the highest technical difficulty in the construction of the Winter Olympic venues in Zhangjiakou Area. Guangzhou Baolun Electronics Co., Ltd. produced professional sound reinforcement, central control equipment to help its audio system construction throughout the process.
According to reports, Polyn Electronics transmits audio through the network in the arena to achieve zero delay in audio transmission, effectively ensure the synchronization of audio transmission, and ensure that athletes can clearly and timely hear the start command of the game said by the host. At the same time, according to the needs of different venues, a number of professional waterproof line arrays and waterproof speakers are designed in the competition area and the audience area to cover the dead corners of the sound source better, make the sound field more uniform, and create a good atmosphere on the field.

The luminaires used in the opening ceremony are 100% made in China
Among the Guangdong performing arts equipment enterprises participating in the Beijing Winter Olympics this time, many of them are already "veterans of strength" who have been "experienced in the battlefield". For example, the LAX sound reinforcement system developed and manufactured by Guangzhou Ruifeng Audio Technology Co., Ltd. has lived in the "Bird's Nest" for 14 years. After the 2008 Beijing Olympic Games, the 2015 World Athletics Championships and other large and small events and events, the parameters have remained outstanding. In December last year, Ruifeng Technology sent technical backbone personnel to form a support team to settle in Beijing and Zhangjiakou. The National Stadium "Bird's Nest", the National Speed Skating Hall "Ice Ribbon", the National Alpine Ski Center "Snow Flying Swallow", the Shougang Ice Hockey Hall, the Beijing Ice Project Training Base and other competition training venues. In addition, the team also undertook the special lighting projects for sports display in five major venues, such as the National Speed Skating Hall, the National Aquatics Center, the Wukesong Gymnasium, the National Ski Jumping Center, and the Genting Ski Park.
In 2008, Dispu undertook the construction of the public broadcasting system project of 10 important projects of the Beijing Olympic Games "six halls, two districts, one tower", which made positive contributions to the success of the Olympic Games. This year, with the advantages of excellent performance products, reliable services, and more than 30 years of old brands, Dispu has once again been recognized by the Olympic Organizing Committee, providing 4K visual distributed integrated management platform, conference system, professional sound reinforcement system and other supporting facilities for the 2022 Beijing Winter Olympics.
The stage lighting control equipment provided by New Stage Lighting has been applied to major events such as the 2008 Beijing Olympic Games and the 2016 Hangzhou G20 Summit. According to He Shoufeng, Guangdong lighting enterprises have been greatly trained in large-scale activities such as the 2008 Beijing Olympic Games and the Asian Games and national celebrations in recent years, and the industry has made great progress, gradually occupying the whole country and even the global market.
According to reports, during the 2008 Beijing Olympic Games, about 50% of the lamps used in the bird's nest were imported equipment. At the opening ceremony of the 2022 Beijing Winter Olympics, 100% of all the lamps and lanterns used in the whole venue were made in China. At the same time, at present, "China's performing arts equipment products have occupied more than 80% of the world's market share, of which Guangdong enterprises account for 80%!" Liang Zhiyuan said, "Guangdong has a large number of products such as lighting, audio and other products have been exported to developed countries such as Europe, america and Japan, and have become one of the high-quality representative industries of "Made in China".
He Shoufeng predicted that after the Beijing Winter Olympics, the performing arts equipment industry market will once again usher in a breakthrough development. "The opening ceremony of the Winter Olympics is no longer just the traditional use of lighting and sound products, but the integration of various high-tech means into the stage. This will lead the transformation of the domestic performing arts entertainment industry to a certain extent. ”
