A lighting system includes a digital addressable lighting interface (DALI) master controller, a lighting driver, and a signal converter. The DALI master controller is connected to a management server. The lighting driver operates a lighting device including a light emitting diode (LED). The signal converter is connected to the DALI master controller by a DALI bus operating according to a DALI communication protocol, and is communicatively connected to the lighting driver via a wireless communication connection operating according to a wireless communication protocol. The signal converter inter-converts a signal transmitted and received from the DALI master controller according to the DALI communication protocol and a signal transmitted to and received from the lighting driver according to the wireless communication protocol so as to enable communication between the lighting driver and the DALI master controller.
