Abstract: PURPOSE: A lighting control device and a method based on DMX(Digital Multiplex) are provided to automatically set the channels of LED(Light Emitting Diode) lighting devices connected with a DMX512 network and to provide corresponding information to a control console, thereby transmitting a required channel information signal without an extra manipulation of the control console, completely being compatible with an existing DMX protocol, and automatically setting the channel and identifying channel information. CONSTITUTION: A lighting control method based on DMX includes the following steps: a step of receiving a detection signal based on a DMX frame from a DMX control console; a step of determining whether or not a channel is required to be set based on the start code of the DMX frame; a step of extracting channel information from the DMX frame when the channel is determined to be set; a step of determining whether or not the channel information is a predetermined value which is impossible to be set; a step of setting the channel, updating the channel information, and generating updated channel information when the channel information is not the predetermined value; and a step of generating a transmission DMX frame having the updated channel information, and then transmitting the transmission DMX frame to a next lighting device. [Reference numerals] (AA) Start; (BB,DD) Yes; (CC,EE) No; (FF) End; (S410) Receive a DMX frame; (S420) Is a start code zero?; (S430) Extract the last value of the DMX frame; (S44) Set up a starting channel of a lighting device through the extracted value; (S450) Add the starting channel to a usage channel of the lighting device; (S460) Process a DMX signal; (S470) Light a lamp; (S480) Is the sum greater than 512?; (S490) Add the sum to the last of the DMX frame; (S491) Add zero to the last of the DMX frame; (S492) Transmit the DMX frame
