Melanopsin Stimulation Affects Discomfort Glare in Lighting Environment

説明

<p>It has been reported that both luminance and melanopsin stimulation affect the discomfort glare. However, in previous studies, visual stimuli were only presented to a part of the field of view. In this study, we examined the effect of melanopsin on discomfort glare in a lighting environment and attempted to formulate a discomfort glare, including its application in designing interior lighting. A white interior apparatus with a multispectral light-emitting diode light source placed on the ceiling was used, and ten participants evaluated the glare levels under several conditions. Glare perception was evaluated using nine categories corresponding to unified glare rating (UGR) values. Eight conditions were prepared by combining correlated color temperatures (2700, 5000, and 8000 K) and melanopsin stimulation. The luminance conditions of the luminous part were set to approximately 18,000 and 45,000 cd/m2. We found that glare perception was affected by melanopsin stimulation when the correlated color temperature and luminance conditions were constant, but not by differences in the correlated color temperature conditions. Furthermore, we analyzed the results and derived an evaluation equation for discomfort glare as a function of melanopsin and S-cone stimulation added to the UGR parameters. The proposed equation enables the precise evaluation of discomfort glare in lighting environments.</p>
