What cool technologies are used in the behind-the-scenes lighting design of "2022 Spring Festival Gala"

"Behind the scenes design analysis

With the theme of "Happy and Happy New Year", the party focused on the Spring Festival song on the new journey, adhered to the warm and warm main tone, and deeply reflected the centenary of the founding of the Party, rural revitalization, ecological civilization, and the Winter Olympics with novel and unique literary and artistic works. , China's aerospace and other major themes, the art presentation has both the Chinese cultural heritage and the aesthetic pursuit of the times, focusing on the deep integration of technology and art, and presents a "laughing, beautiful, stunning, tearful" for Chinese at home and abroad in a beaming, joyful and auspicious manner. The Spring Festival Cultural Dinner.

This year's Spring Festival Gala is the first time to use LED screens to create a 720-degree dome space. The giant-screen dome design integrates the auditorium with the main stage. The 4,306-square-meter LED screen forms a highly malleable three-dimensional studio space, breaking through space limitations and traditional The performance relationship of the party.

This Spring Festival Gala was led by Cai Wei as the chief lighting designer, and Yang Shuhuai as the lighting designer and led the lighting team to complete the lighting design

The lighting design of the Spring Festival Gala needs to be designed according to the overall conception of the performance by the director team of the Spring Festival Gala, as well as to ensure the overall coordination of the stage beauty and lighting effects . According to the needs of various types of work scheduling and program effects, the lighting plan for 2022 has been designed
 

face light design

In terms of surface lighting, this time, according to the structural characteristics of Hall 1, the stage design designed the auditorium into a dome style, and the entire auditorium was surrounded by the dome. The lighting needs to be combined with the structural characteristics of the stage beauty, and three surface light openings were opened above the rear of the auditorium. , divided into three layers:

On the first floor, 32 cutting lights are used for surface light, 31 moving head lights are used for audience backlighting, and 5 PTZs are used for chasing light;

On the second floor, 30 cutting lights are used for surface light, 34 moving head lights are used for audience backlighting, and 5 PTZs are used for light;

On the third floor, 30 cutting lights are used for the surface light, and 36 moving head lights are used for the audience backlighting.

According to the stage structure, a pan-tilt chasing light is installed on the first and second layers of light, and lamps with cutting function are also used for the stage surface light. In effect, the surface light is kept clean and thorough. At the same time, because the surface light follows the structure of the dome, the light is arranged at an arc angle, which can also enrich the angle of the surface light, enhance the layered and three-dimensional sense of the stage lighting, and can also take care of multiple machines. bit lighting requirements. At the same time, some bee-eye moving head LED lights are interspersed and hung in the overall surface light structure, so as to create an atmosphere of the auditorium and enhance the level and volume of the auditorium
In addition, the surface light of the auditorium is suspended by a liftable CNC electric hoist, and 24 cutting and dyeing lamps are used, which increases the flexibility while ensuring the lighting. The surface light behind the auditorium is set on two 6-meter truss racks suspended by numerical control above the curved screen of the stage. Each beam is hung with 6 cutting computer lights, which mainly supplement the surface light in the rear area of ​​the stage.

main stage

The choreography in the main stage area consists of 5 circular arches. Lighting According to the design concept of stage beauty, lighting racks are added behind the arch to form an arc shape together with the stage beauty to enhance the modeling level and make the overall effect more perfect.

The light position of the main stage area is composed of the same arc light frame welded behind the curved screen and a numerical control lifting beam in front of the main screen.

The six lights on the stage use spot cutting lights as the stage backlight, and the angle of the light is more strictly controlled, which is convenient to control the stray light, capture various small lights in the picture and show them truthfully, so that the overall stage looks very clean, and achieves the use of light to create an atmosphere. the goal of. To better match the program, cooperate with matrix and dyeing lights to achieve the best lighting effect
The side light of the stage also adopts CNC electric hoist to lift and lower to match each program. The side light adopts 5 sets of customized lighting racks, and all the side light racks are CNC electric hoists. Bringing more flexible play that can move lights.

The lighting design is also more cautious in the selection of lamps. The selection of lamps pays attention to the unity of optical quality of lamps and the stability of lamps, which can meet the technical indicators of 4K recording and broadcasting of TV for the Spring Festival Gala in 2022, and take into account the viewing effect of the audience. .

AR design

In the 2022 Spring Festival Gala, the AR production team of the five packaging islands (CCTV digital) recorded by the Technical Bureau of the General Station successfully completed the AR creation and on-site implementation. The team continues to promote design and production in accordance with the goal of "integration and innovation of technology and content, technology and art". AR virtual vision technology breaks through the limitations of time and space, allowing the audience to experience the beauty of the fusion of technology and art.

The AR team formulated the general direction of "using AR skillfully" in the early creative stage of AR in the Spring Festival Gala this year. The dance program "Only Blue and Green" did not perform three-dimensional processing of "A Thousand Miles of Rivers and Mountains" in accordance with the traditional creative method and placed it in the foreground of the stage to become a large environment, but designed a slowly rippling water surface in the foreground. Using the technical art means of the "next-generation" engine, the entire space environment is dynamically reflected in real time, making the beautiful dance itself an AR content
The AR content is also integrated into the program. Although the overall picture is simple and clean, it is in harmony with nature and beauty. It was not until the last picture of the program that we added the vague "A Thousand Miles of Rivers and Mountains" in the foreground to let the dancers It seems to have entered the "A Thousand Miles of Rivers and Mountains" and become the person in the painting.

In the children's program "Dream of Stars", we built the performance site into an immersive virtual cosmic space. For this purpose, we designed cosmic elements such as stars, nebulae, galaxies, galaxies, and planets extending around the auditorium. Use them to cover the auditorium and all hollowed-out vistas on one level to enhance the spatial relationship effect produced by the movement of the rocker position. In addition to shaping the atmosphere of the environment, we also designed two AR elements that interact with the actors on the stage: Feather and Space Station. The feathers fall synchronously with the solo dance of the actors, and the space station cooperates with the actors to tell the synchronous flight, making AR elements truly an important part of the program content itself.

In addition to the above two key programs, we also used AR augmented reality technology in the opening programs "Love Together", "Spring Breeze Ten Thousand Miles", "Spring Bells", "Unforgettable Tonight", Magic and Zero Point. Breakthroughs in technical art and content innovation that break with tradition are the two highlights of AR at the Spring Festival Gala this year.
