OLEDs are flat sources of light. The light they emanate is characteristically diffuse but at the same time bright, with good colour reproduction, and along with the LED they are seen, in view of their energy efficiency, as being the luminaires of the future. Under the auspices of a KTI-sponsored research project, the OLED Design Lab has been investigating the design and technical potential of this new technology which is now approaching its market launch, using the OLED modules currently available (Philipps Lumiblade) as a basis. The goal was the prototype development of consumer lamps and lighting systems which are consistently geared to the special features and advantages of the OLED. This resulted in trailblazing solutions, suggested on the one hand by the thinness and lightness of the OLED units, and on the other by the possibility of digital controls and their system-forming potential. Interactive light installations and lamps illustrate what kinds of role may soon be open to OLEDs, in the field of scenography or interior lighting.
