Although the light has become a critical design element for products, the lighting design process remains largely unexplored in the product design. Given this background, this dissertation aims to develop a lighting prototyping tool for designers to support exploration of lighting design in early design stage as well as in refinement to optimize the lighting attributes. In particular, this study tries to figure out the role of lighting prototyping tool desired by designers and to discover the practical value of the tool. To achieve the research goals, literature study on lighting properties were conveyed, and existing lighting design methods were reviewed. The physical and perceptual features of lighting were classified into tangible and intangible aspects, and then the design brief of the lighting prototyping tool was identified. Named as c.light, the tool was comprised of physical component—lighting emitting modules, control module with Bluetooth connection, shape fixation modules, and lighting diffuser parts—and the android based mobile application. C.light enables users to create and manipulate lighting in terms of luminosity, chromaticity, and temporality. To investigate the user experience of the c.light, two sessions of creativity workshop were carried out with domestic and international designers. The participants in both workshops explored the value and effect of lighting as a form factor of a product. The workshop unfolded three major findings: First, the tool supported fabrication of the lighting properties. It reduced the gap between design intention and the actual outcome through explorative and inverted design procedures; Second, simultaneous manipulations of tangible and intangible lighting properties occurred iteratively; Last, the tool easily led the workshop into a collaborative atmosphere. Also, participants benefited from the c.light in learning of lighting as well. In addition, in order to figure out the distinctive characteristics in contrast with conventional ideation method, c.light was compared with sketching. In spite of noticeable advantages of c.light, it showed limitations in expression of diverse forms and in archiving of selected lighting settings. The advancements in physical components and mobile application were implemented in a customized manner along a series of cases studies in industry-academia projects. The tool supported the shaping of lighting by using diverse forms of diffuser. An LED with a structured cover, optical fibers, and LED mounted diffuser panel generated a point light with pattern projection, flexible line lighting, and luminous surface, respectively. In mobile application, buttons were added to retrieve previous lighting selection. When an detailed control over the lighting choice was anticipated, discrete adjustments of R,G,B, or W channels were offered. The cases studies dealt with passenger cars, heavy vehicle(bus), residential space, refrigerator, and clothing care system. According to the stage of lighting design, the case studies are grouped into two—lighting exploration and lighting refinement. Each case study resulted reflections and insights, and the design requirements were finally derived. Based on attempts of making tools and lessons from case studies, this study provides method and evidence to be facilitated by product designers to explore and elaborate the design of product lighting.
