Impact of LED-technology on comfort and emotion in long haul-flights – Psychophysiological analysis of the use of activating light in the aircraft-cabin

Author: Achim Leder, Jarek Krajewski, Sebastian Schnieder

The experience of comfort and positive emotions during a long haul-flight depends on many factors. In addition to seats, cabin climate, vibrations, turbulences and external influences on the flight, light in the aircraft cabin plays another important role. Chronobiologically improved cabin lighting concepts by new LED-(Light Emitting Diode)-luminaires might enhance passengers comfort on long-haul flights by higher in-flight relaxation and higher activation levels at the destination. This study compares currently used cabin lighting with new technology based on LED. In the context of three simulated long-haul flights (within-subject-design: 21:00 – 06:00 h; N=32) comfort and emotion are measured by saliva-melatonin & -cortisol, self-reports, observer ratings and webcam based automatic facial expression analysis. The results show higher comfort and positive valence in the warm white LED condition.
