“…In addition, lighting companies have released LED light sources with a CRI higher than 95 to realize a spectrum like natural light [19]. However, natural light shows a correlated color temperature (CCT) value of about 2900 K at sunset and about 6000 K or more at noon on a clear day [20]. Natural light provides high CRI light under different light and color conditions every moment.…”

Natural light continuously changes its correlated color temperature (CCT) from sunrise to sunset, providing the best color reproducibility and healthy light. In the lighting field, efforts have been made to improve the Color Rendering Index (CRI) to provide light quality at the same level as natural light. A unique light source technology that mixes and controls multiple LED light sources with different spectral or CCT characteristics or provides a high color rendering index has been introduced. However, the characteristics of natural light, which provide high CRI light while changing color temperature every moment, could not be reproduced as they were. Therefore, in this paper, we propose a CRI-based smart lighting system that reproduces natural light characteristics, provides light with high color reproducibility, and maintains homeostasis even under the changing environment of natural light CCT. After extracting the CCT for each day from the characteristics of measured natural light, the light with the highest CRI under the CCT condition for each hour was provided through a CRI-based CCT matching algorithm. Performance evaluation was conducted for four-channel LED experimental lighting. For each clear and cloudy day, daily natural light was reproduced with a light quality higher than average CRI 98 within the MAE range of CCT 6.78 K.

Color as a Key Factor in Creating Sustainable Living Spaces for Seniors

Color as a feature of interior spaces is a fundamental component of human interaction with the built environment. Therefore, planning the design concept of an interior space with attention to color choices is extremely important, especially when the users of a given space include individuals who require additional support and care, such as the elderly. The colors used in architecture and interiors play a crucial role in the well-being of older adults, influencing their spatial perception, behavior, and activity. With age, color perception changes due to the effects of the aging process on vision. Visual deficits lead to shifts in sensory perception, which can, in turn, affect the sense of well-being, often creating a heightened sense of uncertainty. These changes in color perception due to aging may impact the color preferences of older people within their living environments. To create supportive environments for seniors, it is necessary to investigate which colors are most easily recognized, which colors are easiest to distinguish, and which colors are preferred by older adults. Based on a review of the literature and research findings on age-related changes in chromatic and spatial perception, design recommendations and guidelines have been developed. To supplement this knowledge, a survey was conducted among seniors to gather insights on their color preferences. Observations and analyzes of the survey results point to strategies for color use and underscore the importance of color in designing sustainable living spaces for seniors.
