The study found: office lighting can let the staff sleep 26 minutes

Holland Technische Universiteit Eindhoven (Eindhoven University of Technology) a study showed that installed in the office of personalized, adjustable lighting, can let the staff average sleep time 26 minutes.

In the study, the more cold brighter lighting, and the light intensity and color temperature can realize the control of the environment, the staff report said the duration of sleep improvement.

The office staff at first in the lighting environment randomly selected for 3 weeks, then stay in the new experimental environment in the next few weeks. The control group is the standard office staff to accept the average illuminance of 500 lux, neutral white light illumination, and the test group employees accept is the dynamic lighting with different color temperature and intensity. These lamps are depending on the age of the subjects of custom.

The researchers measured close to the eye light, personalized group employees exhibit higher levels of illumination in the morning, near the desktop and eye color level is higher.

According to reports, in the individual group, prolong the average sleep time is 26 minutes.

In order to verify the results, the researchers will conduct further detailed analysis, in order to control the potential variables, such as light sensitivity, general sleep quality and evaluation period and the optical recorder measured actual illumination.

The present study results for reference only, because there is no conclusion. However, this shows the importance of personalized.

Another finding is of light intensity and temperature varied views. The report said, "the survey results clearly indicate the need for personal control".

"We understand that, even if the individual control just happen, users will love setting lighting scene function."

In the study, only a handful of participants will realize that light has influence on the sensitivity, health and productivity. If you can control it, most of the participants will be transferred to the comfortable degree of light. (compiled: LED James)
