Method for reporting brightness-adjusting data, lighting device, and gateway

A lighting device, comprising a light source, a power supply component, a communication module, and a control module, wherein:

• the power supply component provides power for the light source, the communication module, and the control module;
• the communication module receives a brightness-adjusting command from a terminal device, the brightness-adjusting command containing brightness-adjusting data having a desired brightness value;
• the control module adjusts a brightness value of the lighting device to the desired brightness value;
• and
• the communication module reports the brightness-adjusting data and a serial number corresponding to the brightness-adjusting data to a gateway after the control module completes adjusting the brightness value of the lighting device, wherein:
• the gateway includes a processor and a communication module,
• the serial number increases in accordance with a sequence the brightness-adjusting data are reported to the gateway,
• the processor of the gateway determines whether the serial number is greater than a latest serial number stored in the gateway,
• when the serial number is greater than the latest serial number, the communication module of the gateway reports the brightness-adjusting data to a server, the server updates a brightness-adjusting result according to the brightness-adjusting data, and the processor of the gateway updates the latest serial number with the serial number, and
• when the serial number is smaller than the latest serial number, the processor of the gateway discards the brightness-adjusting data so as to maintain previous brightness-adjusting data in the server.

A gateway, comprising:

• a communication module, and a processor, wherein:
• the communication receives brightness-adjusting data and a serial number contained in the brightness-adjusting data sent by a lighting device, wherein:
• a brightness value of the lighting device is adjusted to a desired brightness value of the brightness-adjusting data;
• the processor determines whether the serial number is greater than a latest serial number stored in the gateway;
• when the serial number is greater than the latest serial number, the communication module reports the brightness-adjusting data to a server such that the server updates a brightness-adjusting result according to the brightness-adjusting data, and the processor updates the latest serial number with the serial number;
• and
• when the serial number is smaller than the latest serial number, the processor discards the brightness-adjusting data so as to maintain previous brightness-adjusting data in the server.
