Claim Text:
1. A light-emitting diode (LED) lighting control system, comprising: a central control device configured to transmit a lighting control signal, which includes a control data signal for being used in controlling one or more LED modules and a control instruction signal for controlling the LED modules in accordance with the control data signal, to a plurality of channels, the control instruction signal being based on one of a unidirectional communication protocol and a bidirectional communication protocol; a converter configured to be connected to one of the channels and determine whether the lighting control signal is based on the unidirectional communication protocol or the bidirectional communication protocol in response to the lighting control signal including channel information of the converter; and a driver configured to be connected to the converter and control the operation of a plurality of LED modules in accordance with a control data signal transmitted by the converter, wherein the converter is further configured to determine whether the driver is based on the unidirectional communication protocol or the bidirectional communication protocol and convert the communication protocol of the lighting control signal in response to the communication protocol of the driver being different from the communication protocol of the lighting control signal, wherein the plurality of LED modules are controlled by a current, the LED lighting control system further comprises a current-to-voltage converter configured to convert a current applied to a first LED module, which is one of the plurality of LED modules, into a voltage and a plurality of comparators configured to compare the voltage with a plurality of reference voltages, which are set in advance, and generate a plurality of digital values based on the results of the comparison, wherein the plurality of comparators are further configured to include a first comparator generating a first digital value by comparing the voltage with a first reference voltage, which is a voltage for driving one of the plurality of LED modules and a second comparator generating a second digital value by comparing the voltage with a second reference voltage, which is a voltage for driving two or more of the plurality of LED modules, and the converter is further configured to compare the plurality of digital values with control data included in the control data signal and detect any faulty LED modules from among the plurality of LED modules.
