For example, for ranging component a (i.e., ranging component 140 identified as "a"), the detection information obtained by controller 150 from ranging component a includes identification "a" of ranging component a and the distance between the user detected by ranging component a and the shelf on which ranging component a is located. The controller 150 reads the distance detected by the distance measuring assembly 140 from the detection information, compares the distance with a preset distance threshold, and when the distance is smaller than the preset distance threshold, the controller 150 controls the lighting device 110 with the same identifier as the distance measuring assembly 140 to be turned on so that the lighting device 110 sends a commodity information acquisition request to the server 120, assuming that the user is currently in front of the shelf where the distance measuring assembly 140 is located.
For example, assuming that the user is currently located in front of a certain shelf, the identifiers of the ranging assembly 140 and the lighting device 110 that are set on the shelf are both "a" (denoted as ranging assembly a and lighting device a), the controller 150 controls the lighting device a to be turned on if the distance between the user and the shelf detected by the ranging assembly a is smaller than a preset distance threshold value from the detection information acquired by the ranging assembly a, and after the lighting device a is turned on, sends a merchandise information acquisition request carrying its own identifier (denoted as "a") to the server 120 to acquire the display information of the merchandise on the shelf from the server 120.
Through setting up the range finding subassembly on the goods shelves, when the distance between user that the range finding subassembly detected and the goods shelves is less than preset distance threshold value, the controller just controls and opens with the same lighting device of range finding subassembly sign, can avoid the unanimous electric energy waste that is in the on-state and leads to of lighting device.

And then, the LiFi chip in the second LiFi communication module decodes the data received by the LiFi receiver to acquire the display information.
In the embodiment of the present application, each of the lighting devices 110 includes a plurality of LED units, wherein some of the LED units are LiFi emitters of the first LiFi communication module, and other parts of the LED units are used for lighting. Therefore, the LiFi emitter and the LED are separated, when interaction is needed through optical communication but illumination is not needed (such as in the daytime), only the part of the LED units corresponding to the LiFi emitter are turned on, and waste of electric energy caused by the fact that all the LED units are turned on can be avoided.
