A Kansei Engineering Study of Emotional Lighting Design: A Dual-scale Approach

抄録

New lighting applications aspire to provide more benefits than simply allowing vision by improving mood, sleep quality, and daily performance. Based on the admission that luminaries appear differently when lit and non-lit, the study employed a dual-scale Kansei approach for the evaluation of wall sconces for creating of an intended lighting atmosphere in the dark while having a specific, invisible appeal at daylight. The study determined: (a) the relationship between the appeal of non-physical (emitted light pattern) and physical (shape and size) design attributes on the lit space when the sconce is switched on; (b) the effect of sconce shape and size on different interior impressions when lit and the sought out invisible impression when non-lit; and, (c) the personal lighting profile of one participant by the use of the selected set of sconces as a catalog. Factor analysis and partial least squares were applied for the statistical analysis.
