Abstract
PURPOSE:To enhance the executing easiness in wiring the power supply line and eliminate troublesome settings and alteration by delivering a dimming control data from a main board in such a way as carried by a transmission signal containing synchronous signals, sensing the synchronous signals with a terminal unit, preparing a phase control pulse signal, delivering it, and dimmed lighting the load with a lighting fixture on the basis of the pulse signal. CONSTITUTION:A main board 1 uses the zero cross point of power waveform as reference and delivers a transmission signal containing synchronous signals before the zero cross point. A terminal unit 2 receives this signal through a transmission I/F 21 and senses the synchronous signals in the transmission signal with a synchronous signal sensing part 23. The address in the transmission signal is compared with own terminal unit address at an address judging part 22, and in case they are identical, the sent control signal is analyzed to obtain dimming control data. On the basis of this dimming control data, a by-systems dimming data preparing part 24 prepares a phase control pulse signal having a certain width classified by systems of lighting fixtures. This phase control pulse signal is delivered via output I/F 26 grouped by systems of lighting fixtures. Thereby the lighting fixture can be used by introducing the power without conciousness about the phase.
