To evaluate the change of light perception in interior space, the experiment was conducted in the darkroom controlled at Munsell blackness. By using the method of semantic differential, a total of 16 trials consisted of two types of fruits, two levels of color temperature, color rendering index and illumination, respectively, was set. The data obtained were analyzed by ANOVA (Anlysis of Variance) with SPSS software. The changes in phycological condition of consumers as affected by various illumination conditions of LED lights were found as following:
1. The highest transactional value of purchase for fruits under various illumination conditions was obtained when color temperature, illumination and color rendering index of LED light were 4000°K, 70 CRI and 1500 Lux, respectively.
2. The highest transactional value of purchase for guavas was obtained when color temperature, illumination and color rendering index of LED light were 4000°K, 70 CRI and 750 Lux, respectively.
3. The highest transactional value of purchase for apples was obtained when color temperature, illumination and color rendering index of LED light were 4000°K, 70 CRI and 1500 Lux, respectively.
The results showed a significant difference in appearance of fruits under various light sources. It was worthy to further investigate the transactional value of purchase for various colors of fruits under various types of light conditions. The results obtained in the present work will provide the information for illumination designers and fruits suppliers to improve the illumination conditions with higher transactional value of purchase.
