a plurality of lighting apparatuses installed above a plurality of products displayed inside a room; and
a management apparatus capable of communicating with the plurality of lighting apparatuses and a mobile terminal apparatus functioning as a search apparatus configured to allow a customer to search for and designate a target product of the plurality of products, wherein
the management apparatus changes an emission color of the lighting apparatus associated with the target product to a pre-specified emission color in a case where the management apparatus receives identification information of the target product that the customer designated from the mobile terminal apparatus,
the management apparatus calculates distances between the search apparatus and a plurality of wireless LAN access points installed in the room by using intensities of radio waves received from the plurality of wireless LAN access points via the mobile terminal apparatus,
the management apparatus identifies a location of the mobile terminal apparatus based on the calculated distances and already-known location information of the plurality of the wireless LAN access points,
the management apparatus determines whether the customer has arrived close to a location where the target product is displayed by determining whether the location of the mobile terminal apparatus is within a certain range of distance from the target product based on the identified location of the mobile terminal apparatus and location information of the target product,
the management apparatus returns the emission color of the lighting apparatus to an original color in a case where the management apparatus determines that the customer has arrived close to the location where the target product is displayed.
