Abstract: This study has been conducted on preference of LED lighting as a basic research to calculate systematic and emotional LED color sensibility optimization for optimizing emotions for sapphire LED display. For the research, collection of various emotional vocabulary used in purchasing sapphire jewelry was preceded. Methods/Statistical analysis: The LED color and the emotional vocabulary to be evaluated are preceded in the consideration of the LED lighting, and the subjective reaction to the color appearance of the LED lighting was evaluated and analyzed. In this study, individual questionnaire survey has been conducted on the LED lighting model for the purpose of the study in a laboratory without a window. The scope of the research was limited that experimental LED lighting color was a mixture of Cool White and LED Blue Color. Findings: As a result, C-Blue 25% 0.89 and C-Blue 50% turn out to have the highest preference of 0.68 and C-Blue 100% sms -1.08, respectively. In addition, preference of C-Blue 25% and C-Blue 50% was higher than that of Cool White at p <.001, and preference of C-Blue 75% and C-Blue 100% was significantly lower at p<.001 appears. Therefore, Sapphire indicated the highest preference of C-Blue25% and C-Blue50% in blue illumination, the lowest preference of C-Blue75% and C-Blue100%, and the preference of Cool White was moderate. Improvements/Applications: As a result, the preference for sapphire in the cool_white and blue illumination used for general display was generally high. In case of sapphire, preference in C-Blue 25% 0.89 and C-Blue 50% 0.68 turned out to be the highest in mixed light. It is expected that follow-up studies shall be done among the general public by further subdividing between C-Blue 25% and C-Blue 50%. When these studies are conducted, systematic planning of LED lighting value for emotion optimization can be made.
