Abstract

PURPOSE:To enlarge the control load capacity per channel of lighting fixture system for dim control of a terminal unit and making the system in small size by performing control through separated supply of power and dimming signal to lighting fixtures when dim control is made from a main operation board. CONSTITUTION:When dimming lightup of lighting fixtures 4 is command from switches on a main operation board 1, it sends a transmission signal over to a terminal unit 2 through the action of a processor. This transmission signal is received by the terminal unit 2 through a transmission signal line 3. The terminal unit 2 receives the signal and compares the address in the transmission signal with its own terminal unit address. In case the addresses are not identical, the signal is thrown. In case identical, the sent data in analyzed and a dimming data is obtained. On the basis of this dimming data, specified pulse signal is prepared classified by system lines of the lighting fixtures 4 and passed to a dimming signal line 6 with which appropriate lighting fixture system is connected. On the basis of this dimming signal, a dimming means 8 dimmed lights up the lighting load by the use of source voltage from the power line 5.
