2. Description of the Related Art Conventional dimming control device (dimming control terminal device)
An example of the B and dimming control system is shown in FIG. This conventional system is an on / off control terminal device for turning on / off the power supply from a commercial power source (not shown) to a plurality of lighting loads (lighting fixtures) L1 to L4 to control blinking (lighting or extinguishing). A, a dimming control terminal device (dimming control device) B that outputs a dimming signal for changing the light output of each of the lighting fixtures L1 to L4, and a blinking switch for turning on / off the lighting fixtures L1 to L4. A monitoring terminal device (not shown) that monitors the operation state and outputs a monitoring signal when the blinking switch is operated, and the dimming ratio of the lighting fixtures L1 to L4 (when the light output at the time of full lighting is 100%). A monitor terminal (not shown) or the like that monitors the operating state of the operation switch for setting the ratio) and outputs a monitoring signal when the operation switch is operated is connected to the parent device M via the signal line Ls. Consists of

The master unit M identifies each terminal unit by the unique address assigned to each terminal unit, and the address correspondence between the monitoring terminal unit and the ON / OFF control terminal unit A and the dimming control terminal unit B. When the supervisory signal is stored in advance and the supervisory signal is received via the signal line Ls, the control terminal device (on / off control terminal device A or A command according to the monitoring signal to the dimming control terminal device B), for example, a lighting command to turn on the lighting fixtures L1, ...
Alternatively, a dimming rate command for instructing the dimming rate of the luminaire L1 and an address (load address) for designating the luminaire L1, ... Which is to be controlled are connected to the on / off control terminal A and the dimming control terminal via the signal line Ls. Output to the light control terminal B.

On the other hand, the on / off control terminal A is connected to the respective lighting fixtures L1 to L4 via feeder lines T1 to T4, and the respective lighting fixtures L1 to L4 are supplied from a commercial power source via the feeder lines T1 to T4. Is provided with a plurality of relays for opening and closing power supply paths for supplying power to the device, and drives the relays in accordance with a lighting command or a lighting command received from the parent device M via the signal line Ls, and lighting specified by a load address. The lighting fixtures L1, ... To be controlled are turned on or off by opening / closing the power supply path to the fixtures L1 ,.

In the dimming control terminal B, each of the lighting fixtures L1 to L4 is sent and wired by the dimming signal line K consisting of a pair of electric wires, and according to the dimming rate command received from the master unit M. The dimming signal (a signal for changing the light output of the luminaire L1, ... To a level according to the dimming rate) is output to each of the luminaires L1 to L4 via the dimming signal line K.

The lighting fixtures L1 to L4 are provided with a light source such as a fluorescent lamp and a dimmer for converting AC power supplied from a commercial power source to the light source and supplying the light to the light source. By varying the output from the dimmer to the light source according to the received dimming signal, the light output of the light source is made to match the specified dimming rate.

The operation of the conventional example configured as described above will be briefly summarized. For example, when the blinking switch of the monitoring terminal device in which the correspondence between the lighting device L1 and the address is set is pressed while the lighting device L1 is off, a monitoring signal is sent from this monitoring terminal device via the signal line Ls. It is transmitted to the master M. The master unit M that has received the supervisory signal recognizes the supervisory terminal device that is the source of the supervisory signal from the address included in the supervisory signal, and the address of the on / off control terminal device A that has a corresponding relationship with this address. A lighting command is transmitted to. It should be noted that the above-mentioned address is a plurality of lighting fixtures L1 to be controlled, which are addresses for specifying the on / off control terminal A.
It is a combination of load addresses that specify L4. Then, in the on / off control terminal device A that has received the lighting command from the master unit M via the signal line Ls, the lighting fixture L designated by the load address by driving the relay as described above.
By closing the power supply path to No. 1, power is supplied from the commercial power source to turn on the lighting fixture L1 to be controlled.

On the other hand, when the operation switch of the monitoring terminal device in which the correspondence between the lighting device L1 and the address is set is operated while the lighting device L1 is on, the monitoring terminal device operates via the signal line Ls. The monitoring signal is transmitted to the master device M.
Upon receiving this monitor signal, the master unit M recognizes the monitor terminal device, which is the sender of the monitor signal, from the address included in the monitor signal, and sets it to the address of the dimming control terminal device B, which has a corresponding relationship with this address. A dimming rate command for instructing a dimming rate according to the operation of the operation switch is transmitted. Then, in the dimming control terminal device B that has received the lighting command from the master unit M via the signal line Ls, the dimming signal according to the dimming rate command received from the master unit M as described above is used. By outputting to the line K, the dimming rate of the lighting fixture L1 in the lighting state is matched with the designated dimming rate.

[0009]

However, in the above-mentioned conventional system, the on / off control terminal A and the dimming control terminal B for the blinking control and the dimming control of the lighting fixtures L1, ...
Since the two types of terminal devices are separately used, the wiring work of the signal line Ls for connection with the master device M becomes complicated, and there is a problem that a great deal of labor is required for construction. On the other hand, when the dimming rate is specified as 0%, the lighting fixture of the type that stops the power supply from the commercial power source to the dimmer and turns it off (hereinafter, this type of lighting fixture is referred to as "dimming cut-type lighting fixture"). However, the conventional system and the dimming control terminal device B have not been able to deal with such a dimming type lighting fixture.
