Method and apparatus for automatically controlling illumination based on illuminance contribution

An illumination control method of any one of automatic illumination control apparatuses each including a lighting apparatus, an illuminance calculator, an illumination information transceiver, a contribution calculator, a luminance calculator, and a luminance controller, the illumination control method comprising:

• calculating, by the illuminance calculator, an illuminance of the lighting apparatus on at least one flat target surface on the basis of information regarding the lighting apparatus stored in a database and flat target surface information received from a user;
• transmitting, by the illumination information transceiver, information regarding the calculated illuminance of the lighting apparatus to at least another one of the illumination control apparatuses, and receiving, by the illumination information transceiver, information regarding an illuminance of the at least other lighting apparatus from the at least other illumination control apparatus;
• calculating, by the contribution calculator, an illuminance contribution of each of the lighting apparatuses on the at least one flat target surface on the basis of information regarding the illuminance of the lighting apparatus and the illuminance of the at least other lighting apparatus for on the at least one flat target surface;
• and
• calculating, by the luminance calculator, a luminance value of the lighting apparatus on the basis of a target illuminance received from the user and the illuminance contribution of each of the lighting apparatuses, and controlling, by the luminance controller, a luminance of the lighting apparatus.

An automatic illumination control apparatus comprising:

• a processor, and
• a memory configured to store units comprising commands executed by the processor,
• wherein the units comprise:
• an illuminance calculator which calculates illuminances of a plurality of lighting apparatuses on at least one flat target surface on the basis of information regarding the lighting apparatuses stored in a database and flat target surface information received from a user;
• a contribution calculator which calculates an illuminance contribution of each of the lighting apparatuses on the at least one flat target surface on the basis of the illuminances of the lighting apparatuses on the at least one flat target surface;
• and
• a luminance calculator which calculates a luminance value of each of the lighting apparatuses on the basis of a target illuminance received from the user and the illuminance contribution of each of the lighting apparatuses to control a luminance of each of the lighting apparatuses for luminance of the lighting apparatuses.
