Ever after the LED knocked the market, it has become more popular to our life as one of the main lighting alternatives. Studies over years put emphasis on whether fluorescent lights can affect one’s working concentration, while few of which discussed if LED lights exist the same effects.
The purpose of this study is to test how color temperature and illuminance of LED affect a staff’s working concentration, emotion and satisfaction. We made a 3 by 3 experiment, including 3 kinds of color temperature and 3 kinds of illuminance. We recruited 315 participants volunteered as subjects during several weeks of period. An ANOVA analysis was produced after the experiment to distinguish if people performed differently when exposed in one of the nine lighting context.
The consequences showed that illuminance had no influence on working concentration, while color temperature did impacts the level of concentration significantly. The subjects performed best under 6500K and 3000K of color temperature. For emotion, lighting condition showed no difference between groups. And illuminance could affect one’s tiredness, it showed that people have less tiredness in 700lx lights. Color temperature also influenced subject’s feel of pleasant and relaxation. People felt least pleasant and relax when exposed in 6500K of color temperature.
Thus, we can conclude that color temperature impacts working concentration can satisfaction. Illuminance impacts one’s working satisfaction. The most suitable condition of lights is the combination of 6500K of color temperature and 500lx of illuminance. People apparently perform best in this light condition.
