Abstract

The report addresses the action factors of the general lamps calculated by means of the quantification methods for circadian rhythm. The general lamps were the store-bought 46 LED and 12 fluorescent lamps. The ranges of the correlated color temperatures and the illuminances of lamps were about 2700-7300K and 100-500 lx. The quantification methods were DIN V5031-100 model, Rea's proposal model, Takahashi's proposal model and Enezi's proposal model. As a result, it was found that the correlated color temperatures and the illuminances from the lamps have influence on the action factors compared with kinds of lamps. This result suggested the action factors between the general LED lamps and the existed lamps were approximately-same as long as the correlated color temperatures and the illuminances between the lamps were similar.
