Abstract

This research looks for appropriate colors of lighting depending on several kinds of feelings, covering not only colors which are on trajectory of a complete radiator but also other various colors, and aims to propose a control algorithm of lighting color of LED considering human's negative feelings. This research consists of three experiments. The first experiment aims to seek an appropriate color of lighting when we feel anger, sadness, happy and joy. The second experiment is to seek for reasons of results of the first experiment and to look for what kind of impression of lighting color leads to comfortable lighting environment. The third experiment aims to look for an applicable control of lighting colors when considering people's feelings. From these experiments, it was found that comfortable lighting color differ depending on feelings and the possibility of an effective use of colors which are not on the trajectory of a complete radiator was shown. Moreover, many elements which lead to comfortable lighting control were found, and as the controlling method which consider those elements was more preferred than the method which does not change colors at all, the usability of controlling lighting colors considering people's negative feelings was proved.
