LED Office Lighting to Promote Performance and Well-Being

Abstract

This paper aims to introduce a research project to investigate and compare the effect of dynamic lighting on people for different light sources in an office setting. Basic differences of short term effects on human between static and dynamic lighting as well as light-emitting diodes (LED) and fluorescent lamps will be investigated in a laboratory study. Two identical rooms will be set up, with the light source LED and fluorescent lamp being the only difference. Four different dynamic sequences will be compared for each light source. Therefore eight lighting situations will be investigated. Long-term effects will be investigated within a field study of one year. To study the impact of dynamic lighting on performance and well-being different methods will be used as questionnaires, tests and the collection of physical data, especially heart rate variability.

Systematic review on the interaction between office light conditions and occupational health: Elucidating gaps and methodological issues

“…They recommended further research to focus on the nature of why some individuals prefer daylight and others do not, how the dose-response curves for alertness, performance and mood should be interpreted, and the effect of daylight on human health in the general population. Moeller et al 23 described a research plan for the investigation of differences in user experience and perception when exposed to different lighting situations. They also highlighted that until now, insufficient attention has been paid to potential OH effects in relation to lighting situations in the workplace.…”
