LED landscape lighting dress thirteen "Water Cube" in the design test

The night light landscape of large stadiums is a major aspect of the 2008 Beijing Olympic games. The film structure of the "world's largest water cube" is particularly eye-catching. After nightfall, it is like a square crystal palace quietly nestled in the "bird's nest" next to the whole body exudes a deep blue charm. The achievement of this beautiful "Water Cube", it is LED (light-emitting diode) landscape lighting engineering.

"LED landscape lighting is the last step of the whole water system engineering. It's like building a house, building a house, and decorating. The last step is to light up the lights, we study is the work! CLP technology group, thirteen senior engineer Zhu Xiaodong told reporters, as a member of the lighting engineering research team, participated in the design and testing, they feel very proud.

Water cube"

LED is a new kind of semiconductor lighting source, which has the advantages of energy saving and environmental protection. In the case of similar color effects, LED lighting and fluorescent lamps, energy saving at least 60%, and no mercury, no waste, no uv.

"Water Cube" is the only one in the landscape lighting LED lighting of the Olympic venues. In order to fully reflect the "Humanistic Olympics, hi tech Olympics, Green Olympics" concept, to show the world China in the field of technical level, in August 2006, the Ministry of science and technology has sent 4 experts, inspects our country all Olympic venues, see one of the most suitable for the use of LED lighting. Zhu Xiaodong is one of them.

When standing in front of the water in the steel frame, with professional vision and years of practical experience, Zhu Xiaodong and 3 other experts look at the water cube. "It is the most suitable for the performance of the performance of the LED lighting carrier. "Because it has the world's largest membrane structure building -- the structure of the most special, in design and modeling is one of the world, need very special artistic expression, in order to achieve the dream and exquisitely carved artistic effect.

LED itself is a high-tech, is still in large-scale experiments, there is not enough experience can learn from. Zhu Xiaodong said: very few foreign countries to build such a large volume of membrane construction, and even the world's largest stadium are not dare to get involved in large-scale application of LED landscape lighting. "

In this project, the state issued a 863 plan major research project "semiconductor lighting system large-scale national swimming center integrated technology research", thirteen as group deputy leader, chair of the LED light source and the lamp, the reliability study of two subjects participated in the study, the landscape lighting technology, lighting control system of the two sub topics.

After repeated demonstration program, overcome a technical problem of architecture landscape lighting field, milepost of high power LED applications and LED distributed control field, the research group decided to adopt the way of lighting light in the cavity, between each bubble water cube are mounted on the LED lamp, through the development of customized one and two times optical lens, without affecting the whole lamp luminous flux under the condition of light re distribution, sorting.

With the occasion of different celebration events, seasonal conversion and on-site interaction requirements, "Water Cube" can show a different "expression" - different brightness, different colors. Dynamic water waves can also be changed from the sea blue theme into other colors, as the sea in different periods of time can reflect the different colors of the sky. In the evening, the blue color of the water molecules will be the construction of the eastern side of the "masculine" National Stadium "bird's nest" echoes. Zhu Xiaodong said, you can also show a goldfish playing in the water screen.

"The use of LED landscape lighting for membrane structures is a challenging task. This unprecedented architectural lighting engineering practice, the achievements of the world's largest single semiconductor lighting landscape lighting engineering. Zhu Xiaodong said, LED with its unique performance for the water cube lighting provides a strong technical basis, so that the artistic expression of lighting into a new stage, but also for its own development has opened up a vast space.

For the water cube landscape strict quality control

Thirteen, is the first domestic semiconductor lighting research institutes, in September last year, relying on the establishment of "National Semiconductor Devices Quality Supervision and inspection center, quality assurance for the water cube landscape lighting. According to the person in charge of the center, the top surface of the water cube elevation, a total of millions of light-emitting tubes. In order to reduce the cost of the project, to ensure the completion of high quality on time, the center began to intervene in the production stage of the light emitting diode, strict production process.

About the water cube project center has also prepared "display LED inspection standards", "1W power LED inspection standards", "National Stadium landscape lighting engineering technology and quality inspection standards", "LED display program", "the use of accelerated 1W power LED accelerated life test plan". At present, the accelerated life test is coming to an end, the overall quality of the water cube landscape lighting to meet the requirements of the indicators.
