Abstract: Disclosed are an apparatus and a system for managing circadian rhythm. The apparatus includes an illuminance measuring portion which measures a bio illuminance value of external light using a circadian lambda filter which passes the external light along according to a circadian rhythm sensitivity curve and a visual lambda filter which passes the external light along according to a visual sensitivity curve, a controller which outputs a control signal for reinforcing a user's circadian rhythm on the basis of the bio illuminance value, and a circadian rhythm reinforcing portion which emits light of a circadian wavelength band toward the user according to the control signal.
