Thanks to the new OLED technology, designers and planners now have a light source at their disposal with which they are actually able to shape light. The OLEDs, which Philips distributes under the brand name Lumiblade, are only 1.8mm thick and can therefore be integrated into almost any material. Due to their size, they are virtually invisible when turned off.
This advanced light source is particularly easy to use if it is integrated into special modules. These OLED modules have a frame made from either aluminum or high-quality transparent plastic. Their main advantage is that all necessary electronics are also located inside that frame, thus allowing fascinating lighting applications to be implemented quickly and simply.
A modified version of these modules, which incorporates four Lumiblade OLEDs into a single frame, was used to create the world’s largest OLED luminaire in a Berlin office building. This breathtaking installation contains 384 Lumiblade OLEDs―equivalent to over 2.4m² of the new lighting technology. It is the only one of its kind in the world.
The luminaire measures around seven meters from floor to ceiling. 24 square frames, each made up of four type CN4 Lumiblade modules with four OLEDs, hang on fine steel cables and are distributed equally across the entire length of the installation. The frames themselves do not only emit light upwards, but their undersides also reflect the light of the underlying OLEDs. In the center of the lighting frames, a dichroic glass panel runs along at the same height as the luminaire. This glass (known as color effect glass) changes color depending on ambient light or the angle from which it is viewed. It therefore offers a unique spectrum of colors, depending on which direction the luminaire is viewed from.
“We see the LED as the future of spotlights and the OLED as the future of surface lighting. With Philips we have found a supplier that already has a tried and tested production process for OLEDs in place. Moreover, as the single source supplier for the luminaire, Philips enabled us to simplify our planning process”, says Professor Volker von Kardorff, whose planning office designed this modern and unique OLED chandelier.
The decision to use OLEDs was based on their ability to light up entire surfaces and on their pleasant and tasteful light, which can be continuously dimmed. In close cooperation with the lighting planners, the experts at Philips delivered both the actual OLEDs and the requisite technology tailored to the dimensions of the installation.
About Kardorff Ingenieure Lichtplanung
Kardorff Ingenieure Lichtplanung is one of Germany’s leading lighting design companies. Light influences the appearance of every room and every surface, and therefore also impacts the atmospheres and moods of daily life. “First understand, then illuminate” is the philosophy that characterizes the company’s work and that engenders an intense relationship with the surroundings, the architecture and the use. Founded in 1997, the company is managed by Gabriele and Professor Volker von Kardorff. The experienced team is based in Berlin and comprises 16 architects and engineers with varying specialist areas and originating from four continents. As an independent planning office, it works on projects from the concept development stage right through to completion.
