Effects of LED lighting on office work performance
This experiment was carried out to study the impact that illuminance and CCT have on office work performance. The lighting system consists of ten LED light panels hung on the ceiling. There were 5 different lighting conditions including three CCTs and three illuminance levels (3501×6500K, 5501×6500K, 7501×6500K, 7501×4000K, 7501×80 00K). Fourteen participants took part in the experiment. Testing methods included visual acuity, attention, typing, reading, critical flicker frequency (CFF), ECG, emotion and lighting appearance questionnaire, and eye fatigue questionnaire. The results confirmed that 750 lux gave the highest task performance with less eye fatigue. At this level, the 6500K condition achieved the highest work efficiency. Hence the overall best work performance occurred at 6500K–7501×. On the other hand, 4000K condition was considered to be the most comfortable lighting since it caused the lowest visual acuity reduction and achieved the highest relaxation and comfortable score
