Investigation of the Non Image Forming Effects of Existing Human Centric Lighting Systems

The paper presents an investigation of the potential for stimulation of the retinal photoreceptors and emergence of non-image forming effects of two different existing human centric lighting systems in an educational building. The radiant fluxes and the spectral power distributions of the letter are measured at different correlated color temperatures and the non-visual potentials of the lighting systems are estimated by means of CIE S 26
