Furthermore, an operation panel 16 for inputting lean lighting, etc. is connected to the 6th/S via an interface 17, as well as a light sensor 1 and a terminal 3. ~3n are connected via interfaces /za and /9.

The terminals 31 to 3n controlled by the main controller/are configured as shown in FIG. 3, for example. Namely.

．． On the ~3n side, the transmission signal from the main controller is input to the microcomputer via the interface. When this microcomputer receives a start signal, it receives subsequent address signals and control signals. Here, since the address signal code of each terminal device 31, 3□ matches its own address code, the lighting equipment "II~4t+4+"21~t specified by each control signal

The lights are turned on at different dimming levels.

However, in conventional lighting control devices.

Although it is possible to control the adjustment level for each terminal device 3I to 3n, for example, the adjustment level for each terminal device 3I to 3n can be controlled. Lighting equipment connected to 3. Since it is not possible to change the dimming level between 4 and 4, it is not possible to perform finely dimmed lighting.

[Purpose of the invention]

The present invention has been made in close view of the above-mentioned conventional technology, and an object of the present invention is to provide a lighting control device that can easily and accurately perform dimming control at the '0' level within each zone. shall be.

[Summary of the Invention] In order to achieve the above object, the present invention provides a lighting control device in which a main operating device and several terminal devices are looked down as shown in FIG. Address numbers are assigned to each of the plurality of lighting fixtures, the lighting fixtures are divided into an initial number of zones according to their arrangement, and the dimming level of each lighting fixture in each zone is determined based on the address. The main controller is provided with means for storing the information and a selection switch for selecting the plurality of zones.

It is characterized in that a lighting command signal including dimming level data is transmitted from the main controller to each terminal device based on the selection signal of the selection switch.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 6 and 7. In the following drawings, the same elements as those in FIGS. 1 to 11 are designated by the same reference numerals.

FIG. 6 shows a schematic configuration of a lighting control device according to this embodiment, and this lighting control device differs from that shown in FIG. 1 in the following points.

That is, the circuit configuration of the main controller 1 is basically the same as that in FIG. ．． ≠! 1~”
14+..., address numbers are assigned to each of the lighting equipment G1. ~Hiroshi 14. . . . depending on the arrangement status, for example, as shown in Fig.
~Bn, and each lighting fixture in each zone B1~Bn. ~ri, 4. ... Create multiple lighting/ξ turns by setting the dimming level for each 9, and store this multiple V lighting ie turn in RAM using the operation panel 16 or card league.
The difference is that a reverse switch 100 for selecting the zone and illumination pattern of the above-mentioned rival is connected to the path 15 via an interface. Here, it is desirable to connect a selection switch/θl that is substantially similar to the selection switch 100 provided in the main controller/to the signal transmission line λ on the load side, so that the zone and lighting pattern can be selected from the load side as well. . The circuit configurations of the plurality of terminal devices 3° to 3n are basically the same as that in FIG. 3, but each terminal device 3. The difference is that a plurality of phase control circuits are provided in the driver 33 in order to change the p4 party level between the plurality of lighting fixtures connected to each of ~3n, 1□~2, 4... and turn them on. .

In the above configuration, for example, the zone Bl+ shown in FIG.

14 r When lighting up each of 22 to 24 at a dimming level of 90%, store this lighting pattern in the RAM/J in the main controller/, and use the selection switch/θ
Read by O or 10/. Then, the CPU // in the main controller / creates a signal format as shown in FIG. 7, for example. This signal format is composed of control signals including a start signal, an address signal indicating the address of the terminal device "3I to 3n," a reset signal, and a data signal indicating the dimming level for each address of the lighting equipment. Such a signal format is multiplex transmitted from the main controller l via the signal transmission line λ to each terminal device 3, to 3n in synchronization with the zero cross point of the alternating current supplied by the power line t.Terminal device On the 31 to 3n side, the terminal device 31+
Since the address signal and the own address code of 31 match, the specified lighting fixtures DA, 1- to G1, G2. ~
The driver 33 is operated to light the μ24 at a predetermined Wako level, and the lighting equipment≠11. ≠111+≠21

This makes it possible to carry out fine-grained training.

In addition, in the Hiro map of the fire example above, each zone B1 to B
n was selected separately for each terminal device 3, to 3n, but this zone could be selected using various methods, such as selecting zones C1 and C3 overlappingly in zones 01 to On as shown in Fig. 2. can be adopted. In addition, zone C as shown in Figure 2
1 and C7 overlap, and this zone C,,a
! If the dimming level of each lighting fixture is selected as a unit, and zone CI rOl is selected using the selection switch 100 or 10/, the overlapping lighting fixtures "H~≠24" are two types of lighting. Therefore, in order to avoid this, by prioritizing the selected π zone, for example 0., the lighting turn according to this zone C1 is given. [Effects of the Invention] As explained above, the present invention provides a light control system for each terminal device. Since the spotlights can be turned on for each of the plurality of connected lighting fixtures, there is an effect that detailed dimming lighting can be easily and accurately performed.
