LED 방송 조명의 색온도 차이에 따른 감성 선호도 연구 = A Study on Sensitivity Preference According to Difference in Color Temperature of LED Broadcasting Lighting

다국어 초록 (Multilingual Abstract)

This study evaluates a human being``s preference for sensitivity vocabulary and quantifies this through statistically empirical analysis by using Semantic Differential as for a change in sensitivity preference according to difference in color temperature of LED lighting that is being used in broadcasting, and aims to suggest evaluation model of sensitivity vocabulary preference for difference in color temperature of LED lighting based on the outcome. For this, experiment was conducted targeting totally 80 people based on 5 pairs of sensitivity vocabulary related to experimental image and lighting in 3 kinds of 3200K, 4300K and 5600K, which differentiated color temperature of LED lighting. 78 copies were used without error in the final analysis. As a result of research, first, the difference according color temperature was statistically verified only in totally 3 pairs of sensitivity vocabulary in warm-cold, natural-awkward, soft-rough. In case of the remaining sensitivity vocabularies in clear-cloudy and colorful-conservative, the statistically significant difference wasn``t shown. Second, as a result of carrying out specific post-analysis on sensitivity vocabularies that were shown significant difference, it was indicated to be felt most coldly in 3200K of sensitivity vocabulary in warm-cold and most warmly in 5600K. Also, in case of sensitivity vocabulary in natural-awkward, the most awkward sensitivity vocabulary preference was indicated in 3200K. Finally, the sensitivity vocabulary in soft-rough showed the rougher sensitivity vocabulary preference in 3200K than 4300K, 5600K. Based on these results, it suggested a model of sensitivity vocabulary preference that an appreciator feels depending on difference in color temperature of LED lighting.
