Lighting at Work : Environmental Study of Direct Effects of Lighting Level and Spectrum on Psychophysiological Variables
09 / 2004 - 10 / 2008
Background: Considering the importance of lighting for daily activity, rhythm, health and well being, demonstrated in different human and animal studies, current study will focus on relation of lighting conditions during daytime work-shift and health and productivity features. There is elaborate knowledge about the human visual needs and there are international lighting norms for working (indoor) environment. However, the norms are based on the knowledge of visual functions. When taking into account, that lighting has more functions besides forming the base (external base) for visual sensation and perception, the other psychobiological functions should be considered when designing the optimal indoor lighting conditions. In this study the attempt will be made to elucidate the lighting demands in work conditions. Methodology: The study of lighting in the built environment has an experimental character, including measuring the effect of light on persons. The final effect of the study expects to be a design of lighting model that optimises the health and productivity conditions in a work environment. A model will be derived from lighting characteristics that are 'positively' correlated with subjective, psychophysiological and performance findings from the studied population.
