THE CONCEPT OF THE WAY OF PLC IN LIGHTING SYSTEM AND THE CONCEPT OF THE WAY OF DECREASING OF BPS

摘要

PURPOSE: A concept using plc in a lighting system and a method for lowering control signal communication speed for using plc are provided to integrate an AC power line with a communication line with the AC power line by PLC, thereby improving convenience in installing the lighting system. CONSTITUTION: An AC(Alternating Current) power line and a communication line are integrated by PLC(Power Line Communication). The rate of a transmission signal of a DMX console is 250K BPS(Bit Per Second). The signal is compressed at 9600BPS to lower the transmission rate of PLC. Therefore, rising of costs of a lighting system is suppressed. And, noise is prevented. When a lighting device is installed in high density, both the PLC and an existing method are used.
