Project Guerrilla Lighting
The concept of Guerrilla Lighting was created by Martin Lupton, director of BDP Lighting, for the purpose of raising awareness of the power of lighting. Under the guidance of a team leader, each member will take part in creating transient lighting designs by using high powered torches, battery powered LED projectors, luminous dot lights and an array of gels and filters. Instructed to be in a specific position and at a given distance from their target, the teams will simultaneously light up various aspects of the Pool of London’s architecture on cue at the sound of an air horn, creating a dramatic spectacle. The installation will photographed, the lighting turned off and then the team move on to the next site.
The teams will be made up of local lighting designers, architects, interior designers and manufacturers, all of whom are keen to draw attention to the possibilities, and importance of, lighting in the urban environment.

RGB LED Facade at Brand New National Lbrary in Belarus
In 2006, Minsk received a new architectural symbol – a brand new building to house the National Library of Belarus. The twenty-three storey library is designed in the form of a rhombicuboctahedron (diamond) and symbolizes the enormous value of knowledge that mankind has stored in books.
“The authors suggested hiding the light sources behind the glass to create an illusion of a giant color display,” continues Kramarenko. “A total of 4646 color-changing LED fixtures were installed all around the building, effectively creating a monitor with 25×25 meter sides and 62 meters in diameter.
“As a result, spectators are able to observe a fantastic show with incredible dynamic plots from hundreds of meters away. It is an extraordinary creative venue for lighting designers.”

Light up the city with Dexia !
LAb[au] is happy to announce you its new urban interactive installation Touch on the Dexia Tower and Place Rogier in Brussels, Belgium. The project takes as a starting point Brussels 145 m high Dexia Tower, from which 4200 windows can be individually colour-enlightened by RGB-led bars, turning the faade into an immense display.
Instead of considering this infrastructure as a flat screen (surface) displaying pre-rendered video loops, the project is working on the architectural characteristics of the tower and its urban context. The characteristics of the building; orientation, volume, scale… are used as parameters to set up a spatial, temporal and luminous concept, which moreover allows people to directly interact with the tower.
On Place Rogier, at the bottom of the tower, a station is mounted where people can interact either individually or collectively with the tower through a multi touch screen. Both static (touch) as dynamic input (gesture) is recognized to generate an elementary graphical language of points, lines and surfaces combined with physical behaviours (growth, weight, …) taking a monochromatic colour palette (background) combined with black and white (graphical elements).
Once a composition is created, it can be sent as an electronic postcard with a snapshot from the tower, taken from a distant location. It is also uploaded on the specific project website ( www.dexia-tower.com ) where people can retrieve their postcard, as electronic and printable format, with Christmas and New Years wishes from Brussels.

Seven Screens - Artifical City Light
Artificial light changes how we see cities, both in functional and, increasingly, in aesthetic terms. Its fascination for artists, designers and architects derives from the fundamental role played by light in human perception. Light can create spaces that exist independently of architectural constructions. Without light, images could not be generated, perceived or reproduced, in films, videos or anywhere else. The latest LED technology even permits images to be made from light. This approach has been adopted now in Munich by realizing the new OSRAM light platform SEVEN SCREENS which combines arts with cutting-edge technologies presented in the public space. In future, and up to twice a year, artists will be invited by OSRAM to develop works referring to the specific context.
Reprojected by Media artists Mader and Stublic, and architect Wiermann, based in Berlin / Karlsruhe, engages in a site-specific and medium-specific way with visual perception. The artists have created a virtual space around the seven light steles. Light apparently coming from elsewhere seems to strike the steles like a spotlight. For the viewer, real space and virtual space appear to co-exist, the two realms intersecting at the masts. Computer-generated figures appear in front of the light and are reproduced as silhouettes on the masts, before disappearing into the surrounding darkness.

LED lighting conserving dark skies
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).

Night Writer
One more great “How To” is comming from The Graffiti Research Lab. The Graffiti Research Lab is dedicated to outfitting graffiti writers, artist and protestors with open source technologies for urban communication.
The night writer extends the functionality of LED throwies by allowing a writer to catch a tag in lights. It’s cheap, easy to make and writes 12-inch glowing letters 25-feet in the air on any iron or steel surface…if you stand on a turned over garbage can.
Graffiti Research Lab could introduce you in multimedia street art, animation on walls, larger projections etc, but the night writer could show you a way and tools to create your own wall animation.

Galleria Fashion Store - Seoul
The Building of Galleria West Shopping Centre in Seoul, Korea, is designed by Dutch architects UN Studio, has become the latest, intriguing style icon in the city and a world first for electronic facade technology. Ben van Berkel of UN Studio in association with Arup Lighting in Amsterdam have transformed the Galleria into a perpetually changing, light-reactive and computer-programmable radiant surface.
4330 discs, each 850mm in diameter, make up the entire facade of the mall. They can be programmed to generate up to 16M colours, showing astounding displays in every imaginable shade. At other times the building can even become a giant billboard, its pixels feeding text or images around the entire external structure.
Each disk houses its own LED luminaire. Together with Xilver Lighting, Gronsveld, the Netherlands, a system was created that is capable of producing 16 million different colors for each disk. At night, the individually lit disks respond to a computer program. “Each disk acts as a big pixel on a giant screen,” van der Heide points out. Mounted on brackets, all fixtures are lamped with four LEDs: two green, one blue and one red. Each emits a single watt. “The double green LEDs product a crisp and cool natural hue,” he says. “Typically, color-changing LEDs have a pinkish-magenta cast. The fixtures at the Galleria have an asymmetric throw that places the hot spots off-center. The disks appear to be glowing spheres,” he observes.
Cost of fabricating and constructing the steel structure was approximately $200 per square foot. This amount also includes the exterior steel supporting beams that span from one column to another to support the aluminum frame, the glass disks, LEDs and wiring. Each luminaire cost $55. The custom design and installation of the control system was $40,000.
