Abstract
We have developed a new type of lighting called “Kansei Lighting” that is distinct from existing lighting
equipment by fusing art and optical technology. The combination of lighting system that produces parallel
light and glass art objects made with a unique manufacturing method mimics nature and reproduces
natural caustics. We also built a prototype and conducted a large-scale evaluation of the effects of this
lighting on humans. This paper describes the concept, features, and psychological evaluation results of
“Kansei Lighting”.
