The influence of different lighting source positions on the visual comfort of refrigerator illumination

Abstract

By adopting the method of user experience, this research studies the influence of the layout of the lighting source for the visual comfort of refrigerator inner illumination. There are three kinds of layout, including the lighting source on the top, at the side wall and at the back of the refrigerator, which are conducted experiments under the environment of nighttime, kitchen, living room, common market and high-end store. The result shows that with the vacancy of the refrigerator, there is few influence of the different layout of light source on the visual comfort under the same environment of external illumination. There is a significant difference on the comfort illumination level on the top light and back light under the nighttime environment. But under other outer illumination environments, there is no significant difference among these three lighting source layout.
