Abstract: In this study, it aims to analyze the emotional response of consumers in the LED lighting environment considering the preference of users according to the types of products, and by presenting guidance on LED lighting for emotion optimized display according to the result, I want to help you with your activities. Methods/Statistical analysis:As for a survey method, literature survey on LED lighting was conducted followed by emotional vocabulary extraction to evaluate emotional evaluation of LED color and product to be tested and subjective reaction to the color display of LED lighting was evaluated and analyzed. In this study,emotional responses of consumers were analyzed in the lighting environment using LEDs for amethyst and sapphire of jewelry. Based on the results, we measured the color balance of Cool White, Red and Blue which are widely used in commercial space. We have studied emotional optimization using LED lighting classified as step. Findings:As a result of examining the difference of preference according to the kinds of jewels in LED lighting, there was no significant difference between the types of jewels in Cool White (p = .126> .05).As for 25%, amethyst was 1.28, (P <.01). As for 50%, the amethyst was 1.11, that was higher than sapphire’s -.68 (p <.01). As for 75%, amethyst was 0.76 higher than -0.25 of sapphire (p <.001). As for 100%, amethyst was -0.69, which was higher than sapphire’s -1.08 Improvements/Applications: The objective of this study is to design the LED lighting system using LED CoolWhite, Red, and Blue LEDs for the experiment and to conduct a limited experiment and questionnaire through design experts and experts. Therefore, extraction of emotional vocabulary used in the questionnaire and general factors from them seem to be more emotionally approaching compared to ordinary people. In the future, it seems to be necessary to further refine the stage of mixed lighting and conduct various studies for the general public.
