A Comparative Analysis of Emotional Response from Dirrerent Age Groups to Changes to Color Temperatura and Illuminances in General Diffused Lighting in Study Rooms

다국어 초록 (Multilingual Abstract)

In a preliminary experiment designed to get the optimum photometric quantity for different acts in a study room, this study conducted a comparative analysis of emotional responses from different age groups to changes in color temperature and luminous intensity in the most basic condition of general diffused lighting. For those in their 20s and 30s, the color temperature was presented in the experimental space as seven stages of 3000 K, 3500 K, 4000 K, 4500 K, 5000 K, 5500 K, and 6000 K. For those in their 40s and 50s, the evaluation presented three ages of 4000 K, 4500 K, and 5000 K while pivoting on 4500 K, which was evaluated as the most preferred color temperature in the experiment for those in their 20s and 30s. The analysis showed that those in their 20s and 30s found 300 lx at 4500K most comfortable, appropriate for behavior, and preferred. In contrast, those in their 40s and 50s found 400~500 to lx at 4500 k the most comfortable, appropriate for behavior, and preferred. In a nutshell, compared to those in their 20s and 30s, those in their 40s and 50s found the higher luminous intensity the most comfortable, appropriate for behavior, and preferred. This is understood as the visual characteristic that appears to the aging eyes of the older groups. Also, the scope of luminous intensity acquired from the experiment has turned out to be minimum twice as bright as the maximum reference luminous intensity of ‘60-100-150 lx’, the scope of luminous intensity presented for my study room or study in the KS home.
