OREANDA-NEWS. Merck, a leading science and technology company, announced today that it will exhibit OLED, LED and OPV installations in Frankfurt, Germany, at Light + Building, the world's leading trade fair for lighting and building services technology. The installations and the stand concept of Austrian artist Siegrun Appelt and Darmstadt-based architect Michel Muller will stage the special aspects of the respective light modules and link them with modern building concepts. The center of attention will be an OLED installation.

"We're delighted to have the opportunity to present our high-quality materials in such a special setting," says Udo Heider, head of the OLED business field at Merck. "We can demonstrate the lighting solutions we are able to develop with our partners and the great future potential that OLED lighting has in our view."

The range of OLED and LED lighting applications is very broad. "The two light sources combined are ideal because they complement each other perfectly," Appelt summarizes. "OLEDs are thin and can be used as area light sources for room design, while LED lighting gives a room definition. I'm very much in favor of refining the two light sources together."

OLED materials can be used to build thin, filigree, lightweight light panels that provide great freedom of design. The installation exhibited at the trade fair will take advantage of this aspect. A unique lighting experience with a natural appearing spectrum awaits the visitors. The panels used for this were provided by Merck's development partners, Konica Minolta, OLEDWorks and Osram. With its livilux product group, Merck offers its customers both vapor-deposition materials and printable inks - highly pure and extremely stable.

The isiphor brand stands for energy-efficient, high-quality phosphors in LED lighting applications. At the trade fair, Merck will be presenting an installation that compares the latest generation of phosphors featuring a color-rendering index (CRI) of 98 with a traditional LED having a CRI of 80. The latest phosphors from Merck are used to achieve this high CRI. They create an LED generation that allows rooms to be bathed in light coming very close to daylight with a CRI of 100.

The architectural installation exhibited at the trade fair will use semi-transparent modules including a lisicon formulation from Merck. These modules were developed in cooperation with Belectric OPV. The OPV technology offers many advantages, especially with respect to building-integrated photovoltaics. OPV modules do not show the performance drop usually observed with traditional inorganic photovoltaics in diffuse lighting conditions and under elevated temperatures - typical conditions found in facades. In addition, the semi-transparent modules are available in various colors and offer architects much freedom of design.
