The story behind the Shenzhen lighting show is "the night is too beautiful".

In September 28th, the Shenzhen central lighting performance, with the theme of "brilliant new era", was officially launched. The main contents include four chapters: Shanhai City, reform window, innovation capital and harmonious environment. The performance finally showed "welcome to Shenzhen", showing that the city of Shenzhen is all inclusive and embodies the spirit and characteristics of Shenzhen's openness and tolerance.

The first show of the lighting show installed about 1500000 sets of lamps, and more than 90% were provided by local enterprises in Shenzhen. The four chapters of the lighting show adopted different ways of expression, such as Chinese classical style and pop art. Ping On Mansion uses the most powerful civilian laser. It is the largest laser in the world, developed by China's own technology.

Creative Secrets

Four chapters to show the spirit and core of Shenzhen

The lighting show in Shenzhen has aroused strong interest and concern among the public since its opening. Recently, a reporter in Nandu interviewed the main unit responsible for creative design and lighting installation to reveal the creativity and technology of a lighting show.

"The four chapters of the lighting show are determined by constant brainstorming. Designers, government departments, media personages and cultural circles have brainstorming for six or seven months in two months." Chen Haiyan, deputy director of the lighting Institute of TONGHENG Planning Institute and vice president of the Qingju residence photoelectricity Institute, introduces the four major chapters of the lighting performance, including the city of mountain and sea, the window of reform, the capital of innovation and the harmonious environment, to show the spirit and core of Shenzhen.

Using different methods of creative expression

In order to show four chapters, the lighting performance used different creative techniques. Chen Haiyan introduced the first chapter of the city of mountains and seas. From the ancient Shenzhen, Shenzhen's largest landform is mountain and sea. It reflects and reconstructs Shenzhen's mountains and sea with the painting style of "thousands of rivers and mountains". Then the city construction of Shenzhen was displayed, and the picture was finally cut back to the sea. This time is the modern sea, drawing on the pop art abroad, "from the ancient Chinese sea to the modern sea, it shows the vicissitudes of the sea."

In the last chapter of "harmony", the harmony between Shenzhen people and green is selected, and Shenzhen characteristic black faced egret is selected. "The picture is based on personification, and the expression is abstract." Chen Haiyan explained that the screen resolution of buildings is relatively low and is not suitable for concrete patterns.

Content will be updated indefinite.

Chen Haiyan introduced that every chapter has different colors, and will try to control it so that the saturation is not too high, so that the color of the upper wall and the color of the computer can be as close as possible. Previously, some netizens evaluated the large area of red, yellow, green and other colors in the lighting performance, which looked a little earth. "This job is more complicated, such as different monitors placed together, there will be color differences." Chen Haiyan explained that in debugging self-test, there is indeed a green switch to red, so that the large area of color brush past, impressions will have an impact. But that's just debugging. There's a big gap between the actual lighting and the performance. And in the photo and video, it will be different from the live watching. If you watch some video clips on the Internet, you will feel very distorted and the color is very leaping. Chen Haiyan said that some scenes require a larger contrast of color contrast. Some scenes require collision and impact of color, but try to avoid using special colors of saturation.

"The lighting show is also equivalent to a display system built in a city. Everyone will feel different about watching movies. Some people will like Hollywood blockbusters. Some prefer literature and art to refreshing, and everyone has different psychological expectations." Chen Haiyan revealed that this performance was made of four chapters, which was made for 40th anniversary of Shenzhen's reform and opening up. After that, the content will be updated frequently.

Technical disclosure

There are 43 buildings participating in the linkage show, and about 1500000 sets of lights are used.

The Shenzhen lighting show is centered on the central axis, Shennan Avenue and other important viewing angles in the central area of Shenzhen. It forms a night scene with the civic center as the core and Ping On Mansion as the landmark. There are 43 buildings in this joint show.

Responsible for the lighting installation is Shenzhen Kaiming electric lighting company. This is a national high-tech enterprise. It has installed lighting projects for important government departments such as civic center and Universiade center. Chen Zhiwen, chief engineer of kiming electric lighting technology, introduces about 800000 sets of lamps and lanterns in the whole project, 750 thousand sets in the square, about 1500000 sets of lamps in total, and 90% of them are produced by local enterprises in Shenzhen. There are also 6 glass box displays produced by Shenzhen enterprises.

"The main person in charge of the City Management Bureau went to the factory to stare at the production schedule. The quality of lamps in Shenzhen was good. Most of the lamps damaged by typhoons were blown away by the typhoon." When Chen Zhiwen analyzed the lighting technology, he said that the biggest highlight was the use of two lights, a small point light source and a large point light source. The small point light source 2 watts is provided by a lamp manufacturer in Shenzhen. The large point light source 15 watts is provided by an enterprise in Guangzhou.

"Design creativity is composed of large and small light sources. This is the first time in the country. The content is provided by Tsinghua, and then we realize the content of the picture in the light." Chen Zhiwen explained that the use of large point light source and the use of small point light source are very different. The big point is 6 meters, and the bigger point is the light and dark changes. For example, the brightness of the screen, the brightness of the large point light source is very high, and the effect of explosion is formed.

The small point light source is installed in the lamp slot of the aluminum profile when it is installed. The large point light source is installed in the aluminum profile, and the installation method of the aluminum profile is made according to the condition of the building. Curtain wall structure is different. Installation is different. For example, Ping On Mansion installed curtain walls, lighting installed two times, the original part of the interior, mainly using the lights of their own safety. Other buildings use hanging baskets, and spiders and other sling. Chen Zhiwen said that more than 1200 workers installed all lamps and lanterns for one month.

Video files are converted into upper wall animation.

How to realize the picture after loading the lamp? Chen Zhiwen explained that it is to realize the spot map of lamps and lanterns, the building is irregular shape now, every lamp has a point, and all the building's point map should be drawn into a blueprint. The company should convert the video files from Tsinghua to the upper wall animation, divide the Tsinghua pictures into the video files of each building, first realize the single performance effect of each building, then control the bitmap to make each building form a picture, and then turn the picture into a program that OSRAM control system can receive. Through the cloud platform of Unicom, the control platform of each floor control system is integrated into the control platform, and the terminal is issued to each building in the lighting center of the City Administration Bureau through the general control room, and the overall picture is formed while playing simultaneously.

"You must not directly play the file, you must convert it to the upper wall animation." Chen Zhiwen explained that the picture we saw was made by a small point light source. From the display screen, one of the pictures was composed of lights from one point to the light source. The density of pixels will form a pixel screen. Far from the building facade, it is a complete picture. In fact, all lamps and lanterns are installed on the building and form a picture through the luminaire itself. But it is necessary to transform the video source files into the animation program of the wall, then the system executes the program, the system controls each lamp, and brightens different colors at different times to form a picture.

There are also planes to facade, because the starting height and direction of the building are different. To view the same picture, we have to adjust the height and the direction. All the program commands are integrated and stored in the console of the master control room.

Chen Haiyan revealed that the technological innovation is embodied in the luminescence direction of lamps and lanterns. From a distance, these point light sources are very bright, but they are not dazzling in the vicinity. This is a special technology of light control. Ping On Mansion uses the most powerful civilian laser, the largest laser in the world, developed by China's own technology.

It is understood that in order to ensure the safety and orderly performance of the public, performances are arranged daily from September 28, 2018 to December 31, 2018. The specific arrangements are as follows: Friday, Saturday and national statutory holidays three times a night, the time is 19:30, 20:30, and; Sunday to Thursday two times per night, the time is "," (after the performance arrangement after January 1, 2019, the public will be invited to make a plan before it is announced).

In order to ensure the safety and order of the performance, police, traffic police and other departments will take control measures according to the situation of the crowd, hoping that the public and tourists will understand and cooperate with them. There is a shortage of parking spaces around the civic center square.

Nanshan "the most beautiful Shenzhen bay" light show, all lamps and lanterns were treated with soft light.

Reporters learned from the Nanshan District Municipal Administration Bureau that, in order to celebrate the reform and opening up 40th anniversary, the Nanshan District government organized the implementation of the main body as the "bright new era and the most beautiful Shenzhen bay" lighting show project construction. The project started debugging in August 26th. At present, the commissioning and optimization is coming to an end. Each lighting show is about 8 minutes, including The four chapters of "Chun Kai Nan Shan", "science and technology Nanshan", "ecological Nanshan" and "time Nanshan" will be officially unveiled before and after the National Day this year.

Du Jianxiang, Co ordinator of the Houhai center landscape lighting project, told reporters that the main venue of the lighting show was chosen in the central area of Houhai, and that the talent Park as the best viewing point was considered after many considerations. "Harmony and diversity" is an important concept at the beginning of the design of Nanshan light show. Compared with the lighting show at Futian Civic Center, the lighting performance in Nanshan is more revealing the development characteristics of Nanshan.

In order to create a comfortable, beautiful, safe and orderly lighting environment, the project design team starts with hardware facilities, lighting and color matching. It is reported that there are different themes in the four chapters of "Chun Kai Nan Shan", "science and technology Nanshan", "ecological Nanshan" and "times Nanshan".

Du Jianxiang told reporters that before talking about the lighting show, the citizens were mixed with different opinions. The beautiful lights reflected the light pollution problem of the city. He revealed that at the beginning of the project, the lamps and lanterns made for the selected lamps were required. All the lamps and lanterns of the lighting show were treated with soft light, so that the people could be seen in the light. While enjoying the beauty, life is not interfered. In addition, the design team also put forward requirements for the flickering frequency of the lights. Apart from the rhythm of some turning points, the rhythm of most of the lighting performances is slow and melodious. "This fusion is what we pursue. Since we started mixing colors, we are very concerned about it. The view of the citizens who exercise, walk and work around the talent park to see whether these lights have an impact on their lives and whether they receive complaints, but the results are satisfactory.
