The client 101 may be an APP, a web application or an applet or the like that is onboard the mobile device.
A controller 102, configured to send a second instruction to the first communication interface a of the first light emitting panel 103a according to the first instruction; when a first link table returned by the first communication interface a of the first lighting panel 103a is received, a query result is returned to the client 101 according to the first link table; the controller comprises a first voltage conversion circuit, a first processor and a wireless communication module, wherein the first processor comprises a plurality of communication interfaces. The first voltage conversion circuit converts the power supply into the working voltage of the first processor, and the processor is communicated with the light-emitting panel through the communication interface and the client through the wireless communication module.
The first to tenth light-emitting panels are used for taking the communication interface which receives the second instruction as an upper computer communication interface, taking other communication interfaces except the upper computer communication interface as lower computer communication interfaces when receiving the second instruction, returning the first link list to the upper computer communication interfaces, and forwarding the second instruction to each lower computer communication interface; when the lower computer communication interface receives the second link list returned by the other light-emitting panels, a third link list is obtained according to the interface number of the upper computer communication interface, the interface number of the lower computer communication interface which receives the second link list and the second link list, and the third link list is returned to the upper computer communication interface. The light emitting panel includes a second processor, a light source driving circuit, and a second voltage converting circuit. The second voltage conversion circuit is used for converting the voltage into the working voltage of the second processor, and the light source driving circuit is used for driving the light source to emit light according to the control signal of the second processor.

Wherein the first link table, the second link table and the third link table are only three types with respect to a certain light emitting panel. In this embodiment, the function and structure of each light emitting panel is the same except that the light emitting panels are located in different positions in the tree topology.
In this embodiment, after the controller 102 sends the second instruction to the first communication interface a of the first light emitting panel 103a, the first light emitting panel 103a uses the first communication interface a thereof as an upper computer communication interface, uses the second communication interface B, the third communication interface C and the fourth communication interface D thereof as a lower computer communication interface, the first light emitting panel 103a returns the first link table to the controller 102 through the first communication interface a thereof, and then the first light emitting panel 103a forwards the second instruction through the second communication interface B, the third communication interface C and the fourth communication interface D thereof.

The second light emitting panel 103B then transmits the second link table to the second communication interface B of the first light emitting panel 103a through its first communication interface a.
