Abstract

LED is regarded as one of the best potential light sources for next-generation lighting. In LED applications, Power Line Communication (PLC) is one of the popular communication techniques, which is used to control the complex lighting system. In this paper, a general LED lighting system based on a novel PLC technology, which is named as P-BUS, is presented. It is made up of four main parts: the master controller, the slave controller which controls the LED module, the DC-DC module and ancillary devices. The communication mode, protocol architecture, circuit structure and frame definition of P-BUS technique are covered and discussed. The control method of the system is introduced. Compared with other communication methods, the proposed P-BUS has many advantages such as fewer communication wires and components, simpler circuit topology and strong interference rejection. A prototype is given to show the advantages of the proposed solution and global system performance is also analyzed.
