Lu Ming secret water cube eyes"

"Water Cube" is the National Aquatics Center is one of the important venues for the Olympic Games in Beijing, known as the "water cube eye" of the "mantle state LED display project" was built by Dalian Ming group. The project is by the organizing committee, the SASAC experts repeatedly inspected the demonstration, in the more than and 20 well-known enterprises at home and abroad in a bid to win the title, creating the 7 world breakthrough, completely independent research and development of Lu Ming Lu Mei chip reached 6 million 600 thousand, known as the "world first screen display state of the mantle". Yesterday, the relevant person in charge of the Ming Road group accepted an interview with reporters, secret water cube LED display of the construction of the state of the miracle.

LED uses 6 million 600 thousand chips

"Mantle Luming state LED 104 meters long, 20 meters high, the main area of 2080 square meters, before the world do not have such engineering precedent, Dalian Lu Ming Group technical personnel from 20 square meters to 60 square meters to 100 square meters and then continue to test, finally obtained the unprecedented size.

Lu Ming Group Chairman Xiao Zhiguo introduction, Lu Ming mantle state LED in the development of the beginning, specially for "steel structure water cube complex tailored display screen with high brightness display chip 6 million 600 thousand Lu Ming self-developed, woven into the curtain curtain shape shape LED full color display. The mantle state LED is composed of 11 thousand banded LED display units, woven into a 2080 square meter curtain display. It does not destroy the original construction of the United States during the day, the evening can change a variety of colors and images.

Olympic games out of the water cube"

Lu Ming Group in the water cube south facade made a 2080 square meters of LED giant mantle display. After installing the end of construction, "mantle Luming state LED" will be held in the water cube with the sports events live broadcast, replay, and support a variety of video and graphic broadcast, broadcast high fidelity closed-circuit television and satellite television programs, compatible with the field around the area of other areas play sound. Through the realization of the LED display of the state of the screen, the indoor game will be displayed in front of the audience.

The world's mantle state LED display the first screen

Lu Ming state of the LED, is the Ming Group in the 2008 Olympic Games in Beijing, a world-class outdoor special display project, known as the world's first display of the LED screen, is applying for the Guinness book of world records.

Xiao Zhiguo said that the birth of mantle state LED breakthrough has seven of the world's first: the world's first "invisible" big screen; outdoor video source technology innovation and application of virtual world; imaging technology is the world's first; outdoor large screen picture in picture function world innovation application; world breakthrough running ultra high temperature environment; ultra long distance imaging of the world's leading world states to show the largest mantle.

Xiao Zhiguo said that in terms of engineering and technology, "stealth" is the "road clear LED" an important feature. Because of its "mantle state", "Lu Ming LED" permeability is very good. During the day the sun, the human eye is difficult to find the internal membrane water cube body has a more than 2000 square meters of the big screen, and the night can through the outer membrane body sends out colorful, 5 kilometers away in the video images are clearly visible.

The success of the birth of invisible screen but also to maintain the integrity of the building design, to ensure the building body of the original, so that people can feel the beauty of the static building itself during the day, you can also enjoy the video screen invisible beauty at night, daytime "invisible, bright night".

Water cube structure is special, only 1 to 2 meters between the different spacing between the two membranes. In this narrow space, there are intricate, criss cross, irregularly shaped steel beams similar to the bird's nest. How to make the display "cut" beams, Lu Ming adopted curtain structure, through the image surround technology has eliminated 568 produce 568 beams to approximate the size of a basketball "black hole", to achieve the image clear and complete display.

Hundreds of times to solve the problem of high temperature resistance

In the stadium moved out of the process, there are problems and challenges. It is well known that the unique membrane structure of the water cube creates a greenhouse effect. Because of the two LED layer of water bubbles in the water cube, the greenhouse effect during the day makes it as high as 71 degrees Celsius during the day.

Lu Ming technical staff Liu Yueming introduction, the general operating environment of electronic products at room temperature should not exceed 50 degrees Celsius, between 50 - 70 degrees Celsius, the distance between the water temperature of the becomes another key test LED. How to make components stable work, Lu Ming quickly organized materials experts, chip manufacturers and technical experts to discuss common design, after more than 2 months to nearly a hundred times the test finally solved the problem of high temperature.

Lu Ming mantle state LED display the construction of environmental engineering is small, only half a meter tall steel frame, basic construction and technical personnel work in the prostrate state, the narrowest place is less than half a meter, in the space of action requires extraordinary patience and perseverance, the staff jokingly referred to himself as "holding the egg rock climbing athletes". Dozens of tons of steel bars are artificially lifted, and a total of 3 sets of steel grids, and no traction can not be fixed. Installation technicians had to climb a tree like a monkey, once carrying a mantle of lights to climb up and down, and then swing in the swing of twenty or thirty meters high fixed. Once again, up and down, "mantle state big screen water cube" on the 6 million 600 thousand high brightness light-emitting chip, this means they must be repeated at least 400 thousand times up and down.

Xiao Zhiguo said, "Water Cube" is the world's first application of "Lu Ming LED" households
