Apparatus and method for transmitting foward/receiving dimming control signal and up/down encoding manner using a common user power line

摘要

An apparatus and a method for transmitting a dimming control signal in an up/down encoding manner. A dimming control value and a number of a desired electronic ballast group are set by the user and then encoded into binary data in the up/down manner. The encoded binary data is set as transmission data. A receiving stage receives the transmission data and performs a dimming control operation on the basis of dimming up/down information and electronic ballast group number up/down information of the received data.
