LED LIGHTING CONTROL SYSTEM

摘要

Provided is a light-emitting diode (LED) lighting control system, and more particularly, an LED lighting control system capable of controlling not only a lighting module supporting unidirectional communication, but also a lighting module supporting bidirectional communication, notifying a central control device of any fault or failure in the unidirectional communication protocol-based lighting module, and removing any delays in lighting control that may be caused by limited communication lines. The LED lighting system includes: a central control device configured to transmit a lighting control signal, which is based on a unidirectional or bidirectional communication protocol, to a plurality of channels; 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.

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.
