After only two years of development, OSRAM has achieved record values in the laboratory for organic light emitting diodes in warm white. With an efficiency of 46 lm/W the organic light emitting diodes for lighting applications (OLED Lighting) have a brightness of 1000 cd/m² and last more than 5000 hours. For the first time it has been possible to improve two crucial OLED characteristics simultaneously as up to now these have generally changed in inverse proportion to one another. Higher efficiency used to mean shorter life, and vice versa. #break# Dr. Karsten Heuser, Director of OLED Lighting Technology at OSRAM Opto Semiconductors is pleased with the excellent intermediate results. “Our development team has reached a real milestone for warm white OLEDs with an efficiency of 46 lm/W (CIE of 0.46/0.42 measured in the integrating sphere) and a life of more than 5000 hours. With this significant increase in efficiency and life, OLED flat light sources are approaching the values of conventional lighting solutions and are therefore becoming attractive for a wide variety of applications.”
