Behind the water cube "The brightness dazzles the eyes." grandar decryption

The opening of the Beijing Olympic Games, the venue of the swimming pool water cube with its unpredictable, dazzling image to win the attention of the world. We can not only see the flickering blue tiles, full of bubbles can see the color of the fish leisurely swimming in the water, and even see a water wave in a circle ripples. When the opening of the Olympic Games, the water cube will simulate the burning flame, colorful fireworks, the dragon symbol of the Chinese nation, the people of the world to welcome wELcome"...... In this special day, high online journalists have an exclusive interview with the Shanghai grandar lighting art landscape engineering company, they are finished water cube final lighting decoration, they lit their perfect water cube, water cube.

As we all know, the Olympic stadium lighting requirements high standards, most of the projects have been occupied by PHILPS, GE and other large foreign companies. Why grandar company can beat PHILPS, GE and other large foreign companies, with the landscape lighting project under the water cube? Shanghai guangmaoda lighting landscape lighting engineering company manager Mr. Li Yingyuan was very calm, with six words: good design, good technology.

In terms of design, foreign aesthetic tend to static and dynamic landscape design grandar accord with people's aesthetic habits. The dynamic landscape in the control system is still a difficult, PHILPS and other companies are still using the traditional stage lighting control system, and grandar have begun to use the advanced Ethernet control system. Grandar company is another service robot, dual academic background master professional manager Li Yingyuan himself is Shandong University semiconductor undergraduate and information science and engineering background, in technology, has the advantages of There is nothing comparable to this grandar.

Li Yingyuan said, the water cube is a square box, a lot of water molecules and bubbles, architectural design itself is the performance of the water quality, the quiet, delicate, peaceful and restrained, and the bird's Nest stadium masculine echoes. The design of the light is through the change of light and color, showing the form of water, texture and change, so that the image of water and art. Secondly, the water cube is one of the main venues of the Olympic Games, in the light of the design needs to reflect the Olympic Games "one world, one dream" spirit, such as the opening of the dragon and the fireworks, fireworks and other concrete landscape effect.

The idea of artistic design is just the beginning, due to the large-scale construction of water cube using ETFE materials, its trendy "bubble" for landscape lighting engineering has also brought a lot of technical problems. The use of ETFT materials is the first time in China, the shape and size of the bubble is completely irregular, how the light is projected on this material, what will be the mechanism, there is no experience. Manager Li Yingyuan said a little helpless: ETFE need light, but not too transparent! Therefore, the outer membrane of the ETFE has been used to make the point of uneven density. These plating points in the shield directly into the Museum of daylight, but also on the installation of the interior landscape lights to block. Grandar company to do a lot of experiments, and produced a special patent lamps can be three-dimensional regulation.

In the choice of light source, the project first thought of the LED light source, only the LED light source to meet the desired effect. But the traditional light source with heat and light radiation, will burn ETFE, long-term will shorten the life of materials was ETFE. And only LED light source does not emit infrared and ultraviolet light, is a green light source. LED rich in color, easy to control the distribution of light, suitable for the performance of a variety of images. The LED light source is more energy efficient than the energy saving lamp, which is more in line with the theme of "Green Olympics".

Of course, at the beginning of the landscape architect budget is not much. After he took out the program, more than the architect's budget for landscape lighting. Because the LED light source in the country is still a new light source, the price is still relatively high, LED energy saving than ordinary lamps 60%, in the long run is very cost-effective. Later, after a demonstration and persuasion, the party was gradually tempted. The LED semiconductor landscape lighting program was later selected as an important research topic of the National 863 program.

The light of the water cube is a strict requirement, the day to basically see the lights, and does not affect the facade of the building, while the night does not affect the room. Finally, the engineers decided to use the "inside" way to light the lamp: LED lamps arranged below the membrane, and then up to illuminate the film. The direction of light and the line of sight of people, people can only see the uniform distribution of light, can not see the light source.

The installation also allows engineers and construction crews grandar went to great lengths: the lamp is installed in the gas under the pillow frame, while the frame is fixed on the steel frame structure. The beginning of the construction of the basic did not consider the light, air pillow has been completed, the building has no scaffolding, scaffolding can not be built, and this ETFE material without dirty, afraid of sharp objects. The installation of the light is the way through the rock climbing, the difficulty can be imagined.

Finally, Li Yingyuan manager proudly said: Water Cube this project can be said to be the world's first LED art lighting landscape engineering, if the opportunity is really worth a visit!
