With the trend of light emission diode in architectural lighting system, existing practices for commercial and residential buildings’ electrical wiring / design to provide illumination, control, protection, and energy monitoring needs to be changed. The proposed “two ends Fed direct current (DC) ring distributor power flow” in this work has very high functionality. Several functions can be identified and implemented as a single entity, providing access to predict total energy consumption including an estimation of energy loss in the transmission, while influencing significant cost savings as compared with the conventional practices. This paper describes the merits of DC Power Flow Integration in architectural lighting system. The design is made possible through the application of fundamental theorems, rules, and principles as related in electrical engineering.



Keywords: LED integration, DC distribution, Design and Applications, and Architectural lighting system.
