An LED(Light Emitting Diode) lighting device using a network is provided to display full colors by forming each LCU(Local Control Unit) with a DMX-512 interface module for device compatibility. An LED lighting device includes a remote control unit(10), an NLCU(Network Local Control Unit)(20), an LCU(Local Control Unit), a switching block(50), and an LED lighting unit(40). The remote control unit remotely controls the LED lighting unit. The NLCU transmits a signal of the remote control unit through the network. The LCU is connected by a cascade communication method and composed of blocks(30a-30n) to output signals for controlling LEDs of the LED lighting unit. The switching block has switching units(50a-50n) to output switching signals for turning on the LEDs according to the signals of the LCU. The LED lighting unit controls the LEDs to display a screen according to the signals of the switching block. |
