This one-hour program introduces how OLEDs create new dimensions in lighting design for a multitude of lighting applications. This technology is not only highly efficient, but its thinness and noble character of light give it great flexibility in lighting design. This session will celebrate the design process and results achieved in real-world applications of OLED lighting. Discover the challenges, rewards, and breakthroughs in applying one of the most exciting technologies of today to invigorate the art and design of lighting. Examine the use of OLED technology through application examples, delve into the many considerations in the design and selection of luminaires, and explore how realized projects can impact human interactions with and perceived importance of light.
