PSYCHOLOGICAL EFFECTS OF LIGHTING COMPONENTS ON VARIOUS USAGES IN NIGHTTIME SHOPPING STREETS

摘要

This research focused on the psychological effects of lighting components in nighttime shopping streets on various usages. First, Interview investigation was conducted, and next, simulated images by which the luminance of the lighting elements were assumed to be variable were evaluated. As results of the experiment, conditions minimum needed for streets, such as safety and sense of security, were demanded also for each of three usages; shopping street, returning-home way, and residential street. However, neither the demand of lighting arrangement nor the demand of lighting element were necessarily corresponding. Psychological effects of the lighting elements such as light leaks from the inside of shops and signboard lights etc. were investigated and one example of the methodof panning the lighting environment which corresponded to the usage of the street was shown.
