説明

The non-periodic fluctuation of artificial lighting in offices was investigated to clarify the threshold at which the fluctuation is perceived. The experiments showed that fluctuation ratio of 0.92-1.06, i.e. 7% of the fluctuation, is not perceived when the observers tried to be conscious of the fluctuation. On the other hand, under the condition of being unconscious of the fluctuation because of assigned visual tasks, the threshold has a broader range (0.8-1.3) and the value rises with the fluctuation period. It is important to dim artificial lighting without causing discomfort to office workers, and the results of this study can be used to better control, fluctuation in office lighting.
