摘要: We report data for a pair of singlestack all-phosphorescent 15 × cm 2 organic light emitting-diode (OLED) panels with high efficacy, long lifetime, and very low operating temperature: Panel 1 has 62 lm∕W CRI ¼ 81 lifetime to LT70 18;000 h at 1000 cd∕m , while 58 82 30;000 . Operating higher luminance 3000 49 efficacy 4000 h. Excellent panel is enabled by stable blue phosphorescent materials system. temperatures are within 10°C ambient temperature was further used as building block demonstrate an OLED luminaire under-cabinet lighting applications. approximately theluminairedelivers570lmwith52 lm∕Wtotalsystemefficacy,CRI 86andCCT 2940 K.© 2012 Society Photo-Optical Instrumentation Engineers (SPIE).
