| Abstract |
The purpose of this study is to conduct comparison and evaluation tests of brightness and color rendering of fluorescent lamps and LED lighting based on features of color temperature, and secure sensibility data of LED lighting by implementing tests to examine preference and sensible images of each luminous source. This study was conducted in three steps. First, test points and measurement/evaluation methods were determined, and light cabinet was set up to simultaneously compare the conventional light of fluorescent lamps and LED lighting. Second, physical features of the selected luminous sources were measured and analyzed. Third, test points of the two luminous sources were measured and analyzed. The result of the study showed that LED lighting in the same color temperature range is felt more brightly than the conventional lighting under the same illuminance. The result of relative color rendering tests showed that LED lighting in 4100K of color temperature range is more natural but LED lighting in the color temperature range of 2900K and 6500K has some problems. The result of preference tests showed that fluorescent lamps are more preferred than LED in all range of color temperature. Test subjects the most preferred a light source in the color temperature range of 4100K regardless of the type of luminous sources. The results of sensibility evaluation were analyzed by factors. The analysis classified evaluation factors into "activity", "capacity" and "evaluation". Among the tree factors, "activity" was found the most influential factor in sensible image evaluation. |
