While shifting from modern society to post-industrial society, social structure is changing from the period which pursues material affluence to that which pursues psychological abundance. Formation of various values along with pursuit of psychological abundance has made the illusion of standardization, massification, and popularization meaningless. Different from functionality oriented approach in the past, today's design requires diversified, multiple and integrated thinking and way in fast-changing social phenomena and stream, and lets human loose from the restriction of time and space thanks to technological development. It appears as new and various attempts along with paradigm shift of the wholle society, however the existing physical and actual things gradually transit to non-physical and non-actual things. Tendency of dematerialization has spread as far as esthetic and environmental genre on the basis of social and philosophical base along with change of consumption culture, and has displayed complex and de-genre aspect. Paradigm shift has expanded the range of communication by changing to user's independent awareness and sensitive concept, among them, light displays various changes of space by taking the role of new medium. Particularly, the light as the media expression beyond the phenomenon of light of traditional concept acts as an essential element to stimulate sensitivity and for experience as an immaterial element which shows this change of space most dramatically. This research aimed at recognizing space in complex dimension, exploring the relation between the light and space through media expression displayed in the realization of immateriality, expanding the meaning of light, and recognizing it as the possibility of creative and future-oriented light space creation which responds to technological development and social change.
