Abstract
Design concepts of light can be divided into two respects, visual plastic and metaphysical meaning. The current research focuses on the second respect. The meaning of light is abstract characteristics(for example, divinity, spirituality, or image) ultimately expressed by visual plastic. Because it makes architectural space abundant, it have been expressed frequently in architectural space until now. The purpose of this paper is to conceptualize and explain and arrange the meanings of light in the category that have been expressed in architectural space from ancient to current. The method of this study is content analysis and case study, and this is supplement by theoretical consideration on the meaning of light(relationship between perception and meaning, elements to form meaning etc.). This study consists of three steps. Firstly, through the content analysis of existing literature and documents, 17 meanings of light are confirmed. Secondly, these 17 meanings are defined and explained in 3 categories(symbolic, esthetic, and experiential character). Thirdly, they are additionally explained and articulated by case study. In the result, various meanings of light that have been fragmentarily expressed in architectural space until now is clearly arranged at a glance. Those suggested design concepts will be basic conferential material, available to the interior designers and students who want to utilize the organised study concepts.
