In order to identify the effect of the daylight duct system on the visual environment, a performance measurement, investigation of customer behavior and a subjective experiment were carried out in a fast food restaurant. It was shown that luminous flux obtained from 1 klx of global illuminance was 200 lm approximately. The SPD of light from the light-emitting surface shows the duct systems decrease the short-wavelength-light and the long-wavelength-light. No obvious effect of light duct systems on customer behavior was found. The subjects at the tables illuminated by the duct system feel space more comfortable and preferable.
