Claim of US Patent No. 10,252,022

1. A lighting control device comprising:a processor configured to select, on the basis of a predetermined criterion, a particular group among a plurality of groups of color of light, said color of light having been categorized into groups on the basis of dominant wavelength, where each group of colors is arranged to influence a vertebrate's thermoregulation in a particular manner,
and said processor further configured to generate a control signal for controlling the dominant wavelength of light emitted from a plurality of light sources in accordance with the selected group of colors;
a transmitter configured to transmit the generated control signal to said plurality of light sources for said plurality of light sources to emit light of the selected group of colors, thereby influencing the thermoregulation of the vertebrate being exposed to the light of the selected group of colors emitted by said plurality of light sources on the basis of said predetermined criterion;
the transmitter configured to transmit the control signal to a climate control device configured to control a climate control system, the control signal indicating whether to lower or increase the output temperature of the climate control system depending on the selected group of colors and to influence the thermoregulation of the vertebrate;
wherein the output temperature of the climate control system is lowered when the predetermined criterion is to lower heating energy consumption of the climate control system, for which criterion a group of colors having a dominant wavelength in the range of about 576-700 nm is selected; or the output temperature of the climate control system is increased when the predetermined criterion is to lower cooling energy consumption in the climate control system for which criterion a group of colors having a dominant wavelength in the range of about 460-520 nm is selected; and
wherein the processor is further configured to form a basis for the categorization of color of light into groups based on properties not defined by the CIE1931 chromaticity diagram.
