This paper is in the system as a DC distribution DCPLC and communication protocal arrangement with respect to system design using RS232c. A separate wire to form the cable network shall be installed. Howere, in situation, DC distribution DCPLC necessary as ㅁ separate front requiring communication standards. Internal networks to organize and verification on that of interior Space formed LED for lighting control systems. The results of this study, LED IoT using designs will be available lighting systems.

This study proposes a new approach to LED lighting has been a commonplace. Current LED light are used to connect directly to an AC power source for lighting. This is disadvantageous in the name of energy efficiency, but the ease of use. There, we propose a LED lighting using a DC in a manner that effectively achieve the energy saving for. Also want to take advantage of the hardware and CAN communication standard DCPLC for the effective use of DC lighting.

That"s the reason why LED lighting has to employ AC power inlet. However, LED is a kind of diode, semiconductor, it"s driven by DC power. With whis reason all of LED lighting should have AC/DC converter in its systems. This converter causes energy loss, it"s the target for lesson the energy loss. To reduce this energy loss, DC power distribution structure can be used. LED lighting system using LVDC is a kind of DC power distribution structure, but LVDC has severe voltage drop which makes non-uniform brightness in lighting system. In this paper, we suggest a novel structure for the uniform brightness in LVDC LED lighting system using IoT based network system. The constructed test-bed system of suggested structure shows this structure can con control the brightness with uniformity.
