Lighting control device, lighting control system, and lighting control method

A lighting control system comprising:

• a lighting device using a plurality of light sources;
• and
• a lighting control device that controls illumination of the lighting device,
• wherein the lighting control device
• acquires direction designation information for designating an illumination direction to which the lighting device illuminates,
• acquires light source information indicating a plurality of light source irradiation directions that are irradiation directions of the plurality of light sources, and
• based on (i) a designated illumination direction that is the illumination direction designated by the direction designation information and (ii) the plurality of light source irradiation directions, causes part of the plurality of light sources to illuminate.

A lighting control method that controls illumination by a lighting device using a plurality of light sources, the lighting control method comprising:

• acquiring direction designation information for designating an illumination direction to which the lighting device illuminates;
• acquiring light source information indicating a plurality of light source irradiation directions that are irradiation directions of the plurality of light sources;
• and
• based on (i) a designated illumination direction that is the illumination direction designated by the direction designation information and (ii) the plurality of light source irradiation directions, causing part of the plurality of light sources to illuminate.
