Use of tunable white luminaires for biodynamic lighting

Abstract

The paper deals with possibilities of applications of luminaires with tunable correlated color temperature (CCT) and their influence on the perception of light scenes and on biological functions of human body. The first part starts with a description of human visual system, physiological effects of optical radiation and principle of perception. The second part shows the analysis of photometric parameters of the sample of tunable white luminaire with variable CCT.
