Several biological benefits of the low color temperature light-emitting diodes based normal indoor lighting source.


ABSTRACT: Currently, light pollution has become a nonnegligible issue in our daily life. Artificial light sources with high color temperature were deem to be the major pollution source, which could induce several adverse effects on human's health. In our previous research, we have firstly developed an artificial indoor light with low color temperature (1900?K). However, the biological effects of this artificial light on human's health are unclear. Here, four artificial lights (1900?K, 3000?K, 4000?K and 6600?K) were used to evaluate some biological changes in both human (in total 152 person-times) and murine models. Compared with other three high color temperature artificial lights, our lights (1900?K) presented a positive effect on promoting the secreting of melatonin and glutamate, protecting human's eyes, accelerating would healing and hair regeneration. These systematical studies indicated that the proposed low color temperature (1900?K) light could provide several significant benefits in human's daily life.
