Pseudo-sunlight organic light-emitting diodes

摘要

Diurnally varying color and illuminance of the sunlight on earth play an important role on the circadian rhythm of living organisms. It is highly desirable if pseudo-natural lights with independently tunable color and illuminance capabilities are obtainable. We hence propose here an original approach of using natural light-style organic light-emitting diode (OLED) panels with different color temperatures to generate artificial sunlight mimicking dawn and dusk hues as well as daylights. Unlike those based on monochromes, these natural light-style panel based mixed lights always yield high quality lights with colors falling along the sunlight locus.
