The night lights of large stadiums will surely be a highlight of the 2008 Beijing Olympics. In the middle, the world's largest membrane structure project “Water Cube” is particularly eye-catching. Like the opening ceremony “Bird's Nest”, the National Swimming Center's 41.18 million yuan LED (Light Emitting Diode) landscape lighting project is undoubtedly the Olympic venue landscape lighting project. The main event.

Under the gentle night, how will the “Water Cube” exude its deep blue water charm?

The "Water Cube" construction period is coming to an end. The reporter visited Shanghai Guangmaoda Lighting Landscape Engineering Co., Ltd. At the end of July this year, the company-led consortium won the bid for the "Water Cube" LED landscape lighting project, and is fully responsible for this. The complicated light and shadow project.

"LED landscape lighting is the last process of the 'Water Cube' system project, just like decorating the house, and finally lighting up the lights, we are doing this work!" Fu Xiguang just returned from Shanghai to the night before, this lighting landscape total The conductor was slightly tired, but when he talked about the meaning of the project, his expression flew up.

Beautiful water cube

Through the creation of 36,000 sets of special landscape lamps, the “Water Cube” at night will show its exquisite and translucent features to the greatest extent, and it will complement the “Bird's Nest” in the east.

Designers get inspiration from the water of nature, the holy Shangri-La, the colorful Yaochi, the light lotus dew, the pure Tianshan ice crystal, through the dynamic lighting effect of the light to simulate the various temperament of "water", explore the refraction of light in the water , transmission and reflection, and finally achieve the effect of water and light.

The concept of art design is only a start. Due to the large-scale adoption of ETFE (polyvinyl fluoride) membrane material on the periphery of the “Water Cube” building, its trendy “bubble pack” brings many technical problems for landscape lighting.

To this end, light efficiency engineer Wang Delin led the "Water Cube" task force to the site for more than 10 light efficiency experiments. "The film is completely different from the ordinary wall lighting method. It is bulged in the middle. Some are divided into two layers, some are divided into three layers and four layers. The degree of bumping in the middle is different. How to use a fixed light Way to show it?"

The uniformity of light projection has always been the most difficult to overcome in the light effect experiment. "The film is very strange. A small number of lamps can make the whole film bright and uniform. You can order a lot of xenon lamps, but the middle place. It’s always a dead end, it’s not bright, you’re affected by the outside, and the width of the film is even 9 to 10 meters. It’s a very challenging problem to penetrate the inner membrane and hit the outer membrane. At present, we are still improving."

Beijing and Shanghai ran back and forth, Fu Xiguang was quite worried about the progress of the project: "The top surface plus the facade, the basic shape of the film is 24 kinds, according to its position, angle (such as the flat and side of the hexagon), probably derived More than 240 kinds of shapes come out, every place is changing! Make a screw, it would have no problem on the drawings, go to the scene, finish, can't fit! The film is not to be ventilated, next to it is a trachea on the Other side! 1578 membranes, how to use this pipe to send one by one? How to avoid this kind of bridge? How can we avoid this? We can't see it on the drawings, you can design it at home, it may not be loaded on the scene, the time is very short, feel It’s calculated in hours every day!”
