Highly efficient lighting based on OLEDs
Incandescent and fluorescent lamps are light sources with sophisticated production technology and functionality, which dominate the today’s general lighting technology. During the last decade the LEDs based on semiconductors have reached a development status, which is beyond its original functionality and application areas (indicator/status/signal lights and display technology). Compared to LEDs lighting based on organic light-emitting diodes is still in the development phase, but shows already a big potential for the light source of the future and will complement the LEDs as second important solid light source: an enormous growth market. Flexible or transparent OLEDs enables completely new lighting solutions. Inside the European project OLLA new highly efficient large area lighting modules for general lighting has been developed. The Fraunhofer IPMS will exhibit the latest results of OLLA: a white flat large area light source for direct illumination.
