On the top-floor observation deck of the Rockefeller Center in New York, a unique, interactive space has been created with the use of intelligent LED lighting supplied by Color Kinetics. Cameras track individual visitors as they move within the space, and signal the LED fixtures to create a series of individual colors and patterns.

Conceptualized by Electroland of Los Angeles, the Target Interactive Breezeway has intelligently controlled LED light fixtures on all its surfaces. Each pixel in the “intelligent skin” is composed of four iColor Cove MX units, tightly grouped. These groupings are located in all available wall and ceiling surfaces, behind translucent glass and backlit by white LED strips. Approximately 1,300 units are employed in total.

Data from four stereo video cameras is combined to locate and individually track up to 30 separate visitors as they enter and walk around the space. Upon entry each visitor is automatically assigned a “personality” by the 3-D tracking system and is in turn followed by individualized light colors and patterns.

Several prominent buildings in Korea have upgraded to LED lighting. The optimal green upgrade would have been to minimize the exterior lighting or eliminate it altogether (see Dark Skies). That said, LEDs do have the green advantages of energy efficiency, durability and the ability to control light intelligently. The GS Tower (seen here) has used an array of RGB LED elements from Color Kinetics to present various images for different seasons, climates and dates, and to provide information on weather, time and different events. The Led fixtures are positioned on the frames of windows on three sides of the building, on the upper floors.

In the 63 Square building, LEDs have been used behind opaque glass panels in the canopy above the store fronts. The canopy contains 1300 high-power RGB LED elements, linked by aluminum channel bars running behind the glass.

LIG Insurance has applied LED lighting to the whole of its headquarters building in the Gangnam area of Seoul. Linear LED bars are located above each window space, and these project light onto screens that are rolled down over the windows at night. A total of 375 1200-mm light bars and 15 600-mm fixtures were used. (See the more photos via the link below).
