Development of Structural Diagrams of Energy-Efficient Led Lighting Systems with Command Transmission Via a Single-Phase Power Supply Line

It is shown that the increase in lighting energy efficiency is achieved as a result of switching to LED lighting devices, which have the ability to dim and have significant advantages over other light sources. The General structure of automated lighting control systems (ALCS), consisting of three levels: the control center, the lighting control board and lighting devices, is considered. The purpose of each level is describe; their functions and relationships are listen. It is note that such systems include hardware and corresponding software. The parameters and capabilities of the ALCS largely depend on the communication channel between the lighting control board and lighting devices show. Various variants of communication channels between these levels are consider wire, radio networks and varieties of PLC technology. Their advantages and disadvantages are noted. It is show that for long lighting lines and to eliminate radio interference and high-frequency interference in the power supply network, it is advisable to use low-frequency PLC technology. The complexity of implementing two-way information transmission in this technology is note, which makes it difficult to automatically locate faulty lighting devices. The existing variants of structural schemes of ALCS are considered. The structures of automated control systems for extended lighting lines are propose, which allow detecting abnormal situations and establishing two-way communication for locating faulty lamps and obtaining information from them.
