OLED Lighting Finds Longer Life

For several years organic light-emitting diode (OLED) lighting has been slowly gaining acceptance in the private jet industry, but the relatively short lifespan of the successor to the current LED (light-emitting diode) system has been holding back the technology. Osram Opto Semiconductors of Regensburg, Germany, believes it has a solution. Until now, according to Dr. Karsten Heuser, extending OLED life has meant compromising efficiency and vice-versa. The Osram development team, said Heuser, has reached “a real milestone” for warm white OLEDs with an efficiency of 46Im/W and a 5,000-hour lifetime, at a brightness of 1,000 cd/m2. “With these significant increases,” he said, “flat OLED light sources are approaching the values of conventional lighting solutions and are therefore becoming attractive for a wide variety of applications.” For additional information, contact Kate Cleveland at Osram, www.osram-os.com, or phone (248) 277-8018.
