The meeting will cover all aspects of solid state lighting ranging from new material development and device physics to the design of efficient luminaire optics. Within the next 25 years general lighting and illumination will undergo a revolution. Incandescent as well as gas discharge lamps will be gradually replaced by highly efficient organic and inorganic semiconductor devices. With both light sources, efficiencies of more than 100 lm/W for white light generation have recently been demonstrated. While inorganic LEDs are expected to be the dominating point light sources, organic devices (OLEDs) will play a major role as area light sources. The tremendous and ongoing progress relies on advances in material science, device packaging and light management
