Design of LED Lighting System Based on Power line Communication

This paper will demonstrate the design technique for LED lighting control using the Power Line Communication (PLC) technology based on the research. LEDs today are the most preferred lighting source due to their low power, high-efficiency and smaller size. Power lines used universally and are a generally accessible communication medium for PLC technology. In this paper, a master and slave architecture are presented which makes use of the half duplex communication where the master unit generates the data pulses and slave receives these pulses at a rate of 1 Kb/s to control the LEDs connected through the driver unit. This device is having ability to control more than one slave using the single master controller. The results have been added to show the successful communication established between the master and slave units. The proposed method is less expensive due to least circuitry and a simple design using half duplex communication. No complex protocols like ethernet employed in this design method.
