Although this efficiency benchmark had previously been achieved, until now the color values of OLEDs have not been within the acceptable band for color coordinates around the Planck curve, as defined by the led high bay light Standard. The color values of the new LED are within this band its light retains the white color at different levels of intensity.
By developing a white OLED with a high light yield, the two companies have completed a major step on the way toward commercial OLED lighting. In the development laboratories, highly efficient semiconductor materials from BASF Research were combined with standard materials and thereby new standards set with regard to color coordinates and efficiency. BASF and OSRAM are conducting research together within the framework of the OLEDs for Applications on the Lighting Marke (OPAL) project. The OPAL project is being sponsored as part of the OLED Initiative of the German Federal Ministry for Education and Research (BMBF). Within the framework of the OPAL project, the experts at BASF are dealing with the material side of the OLEDs and, are developing the optimum component structures in partnership with Philips and OSRAM.
The new OLEDs contain phosphorescent metal complexes as emitter materials and customized complementary materials, which ensure optimum constancy of the color temperatures. That means that, owing to the use of new materials, the diodes are very color-stable even when there are variations in luminous intensity. The challenge now is to optimize the life of these led high bay, especially by stabilizing the blue emitters.
Beyond luminous efficiency, OLEDs offer even more convincing advantages. The laboratory results show that the new OLEDs are five times as efficient as filament bulbs and up to 50 percent more efficient compared with standard low-energy lamps. OLEDs consume much less electricity than conventional sources of light, so consumers in the future will be able to cut their electricity costs with OLEDs.
