It is characterized by including a function of dimming each luminaire based on each arrangement.

If the goods display shelves are placed in the target area of lighting, the lighting from the lighting fixtures near the person may be blocked by the goods display shelves, so the illuminance of the lighting near the person is simply illuminance. It is not possible to achieve lighting suitable for a person simply by raising it.
Therefore, by adding a function to dimm the lighting fixtures based on the arrangement of the goods display shelves to the dimming means, the lighting fixtures can be adjusted so that the illuminance suitable for the person can be obtained in consideration of the arrangement of the goods display shelves. Light can be realized and efficient power saving can be achieved.

Here, the dimming means can be configured by a dimming control device that controls the illuminance of each luminaire. The dimming control device divides the target area into a plurality of blocks, associates the article display shelves visible by the person detected in each block with each block, and associates the surroundings of the person with the said person.
