US 12,588,126 B2 · Illumination system

Abstract

The present inventive concept relates to an illumination system and a method for controlling an illumination system configured to illuminate a zone, the illumination system being further configured to serve a plurality of individuals. The method comprising: identifying one or more individuals of the plurality of individuals present in the zone; for each individual present in the zone, obtaining a respective target light profile, each target light profile comprising time-resolved information about circadian stimuli and color temperatures of light that the respective individual is to be exposed to; assigning a priority to each individual of the plurality of individuals present in the zone based on the respective target light profile; determining a proportion of the plurality of individuals present in the zone; and upon the proportion of the plurality of individuals present in the zone is equal to or above a threshold: controlling the illumination system such that a circadian stimulus of light illuminating the zone is higher than a circadian stimulus of the target light profile associated with the individual having a highest assigned priority.

A method for controlling an illumination system configured to illuminate a zone, the illumination system being further configured to serve a plurality of individuals, the method comprising:

identifying one or more individuals of the plurality of individuals present in the zone;
for each individual present in the zone, obtaining a respective target light profile, each target light profile comprising time-resolved information about circadian stimuli and color temperatures of light that the respective individual is to be exposed to;
assigning a priority to each individual of the plurality of individuals present in the zone based on the respective target light profile;
determining a proportion of the plurality of individuals present in the zone;
and
upon the proportion of the plurality of individuals present in the zone is equal to or above a threshold:
controlling the illumination system such that a circadian stimulus of light illuminating the zone is higher than a circadian stimulus of the target light profile associated with the individual having a highest assigned priority.

An illumination system configured to serve a plurality of individuals, the illumination system comprising:

a light source configured to illuminate a zone;
and
circuitry configured to execute:
an identification function configured to identify one or more individuals of the plurality of individuals present in the zone,
a target light profile function configured to, for each individual present in the zone, obtain a respective target light profile, each target light profile comprising time-resolved information about circadian stimuli and color temperatures of light that the respective individual is to be exposed to,
a priority function configured to assign a priority to each individual of the plurality of individuals present in the zone based on the respective target light profile,
a proportion function configured to determine a proportion of the plurality of individuals present in the zone, and
a control function configured to, upon the proportion of the plurality of individuals present in the zone is equal to or above a threshold, control the light source such that a circadian stimulus of light emitted by the light source and illuminating the zone is higher than a circadian stimulus of the target light profile associated with the individual having a highest assigned priority.
