Abstract: A lighting control system comprises a smart device, at least one luminaire assembly, and a server. A user operates a client app installed on the smart device to communicatively with the server to further control the at least one luminaire assembly. The server comprises a database module, a brightness control module for implementing automatic brightness variations, a mode switching module for cooperating with at least sensor disposed in the at least one luminaire assembly to implement different ambient lighting controls, and a brightness compensation module for cooperating with a light sensor disposed on the smart device to implement ambient lighting control.
