Architectural lighting, art and color-changing LEDs
A number of new projects illustrate the range of applications of LEDs.
New-media artist James Clar is using LED technology in a number of high-profile projects. Clar's award-winning 3D Display Cube, a freestanding matrix of 1,000 individually controllable LEDs, can create a low-resolution, three-dimensional television.
Fully interactive, it can connect to a camera or soundboard for live video and audio, and allow designers to create 3D animations instantaneously without needing to write a computer program.
His most ambitious work will be built in Barcelona, Spain in 2008 with the construction of the Habitat Hotel, designed by Enric Ruiz of Cloud 9 Architecture.
Clar designed the "energy mesh" that will wrap around the building. Made of 500 tri-color LEDs, during the day the individual nodes will collect energy from sunlight.
At night, the mesh will glow in specific color schemes and brightness determined by imbedded photosensors that gauge the amount of sunlight amplitude collected, which will change the building's glow according to seasons and weather.

For this project, 305 m of 24V, 5 x 8mm white-colored LED Light Strip was used. The key feature of the entrance (see photo) is the barrel vaulted roof, simply constructed of "triplewall" polycarbonate sheet with the LED Light Strip inserted within the cavities of the sheets.
This means that the lights are perfectly aligned with the curvature of the roof and are flush with the surface, creating a starry sky effect. The spacing between the LEDs was 100 mm.
White LED text in World Trade Center skyscraper
An LED-based art installation will memorialize the events of September 11, 2001 in the lobby of 7 World Trade Center, a new skyscraper which is the first to have been built at ground zero in Lower Manhattan, New York.

Thousands of moving words of text have been programmed by the artist, Jenny Holzer, to evoke the history of New York. The $700 million building is not scheduled to open until mid-May, although the artwork is already being tweaked.
