The AC power supply line 63 and the transmission signal line 6
4, a plurality of lighting devices 69 and corresponding operation switch devices 70 are connected in a set, and different unique addresses are set to the respective lighting devices 69 and operation switch devices 70. ing. The lighting control device having the above-described configuration is provided with the wall switch 6 that is an operation switch.
Of the 8a, 68b, and 68c, for example, the wall switch 68a
When the up button is operated, the address signal indicating the unique address of the wall switch 68a and the up command signal are transmitted from the wall switch 68a to the main operation panel 62 through the transmission signal line 64.

As a result, the main operation panel 62 is controlled by the dimming terminal device 6.
Of the 5a, 65b, and 65c, for example, the dimming terminal device 65a
The address signal and the up command signal corresponding to the peculiar address are sent to the transmission signal line 64. At this time, since the address signal on the transmission signal line 64 coincides with its own unique address, the dimming terminal device 65a receives the up command signal on the transmission signal line 64 and continuously changes the light amount of the lighting load 67a.

Since b stores different toning data in the memory, the data supplied to the toning control signal output units 24a and 24b are different. That is, lighting load 1 of 2 systems
7a, 17b, 17c and lighting loads 17d, 17e, 17
Toning is performed with toning data different from f. Other configurations and operations are similar to those of the color matching terminal device 15 of FIG.

In the color matching operation in the lighting control device of this embodiment, the lighting load group to be color-matched is such that each color-matching terminal device 15 or 1.
8 is different from the first embodiment in that two systems are provided, but the toning control operation itself is the same as that in the first embodiment. The toning terminal device 15 in this embodiment controls the lighting load groups of a plurality of systems with the same toning data, and therefore corresponds to a multi-lamp load.

Further, the toning terminal 18 controls the lighting load groups of a plurality of systems by different toning data. Therefore, the toning terminal device 18 corresponds to a multi-lamp load as described above, and particularly each system. When the specifications of the illumination load are different and the luminous flux ratio of the illumination load of each color is different depending on the system, it is possible to cope with the case where the light colors need to be matched in each system. For example, the lighting loads 20a, 20b, 20c are 3 of R, G, B.
It is a discharge lamp fixture having a primary color FLR40 type fluorescent lamp, and lighting loads 20d, 20e, 20f are R, G,
In the case of a discharge lamp device having a fluorescent lamp of FPL36 type of three primary colors of B, since the fluorescent lamp of FLR40 type and the fluorescent lamp of FPL36 type do not have the same luminous flux ratio of the three primary colors of R, G, and B. By controlling the same color adjustment data for both types of fluorescent lamps, the color temperatures of the mixed light colors of the FLR40 type fluorescent lamp and the FPL36 type fluorescent lamp are different.

However, if the toning data can be set differently for each type, both types of fluorescent lamps commonly controlled by one toning terminal 18 can be toned at the same color temperature. Becomes On the contrary, for example, when two types of fluorescent lamps of the same type (combination, wattage, etc. are the same) are used for toning, it is possible to use different toning data for each system. It is possible to control different color temperatures by interlocking the mixed light colors of the two illumination loads, which are commonly controlled by the color matching terminal device 18, with each other. For example, lighting loads 20a, 20b,
20c mixed light color is 5000K, lighting load 20d,
It is possible to set the mixed light color of 20e and 20f to 3000K.

In this embodiment, the lighting loads 20 of a plurality of systems are used.
Even when the lamp type (combination of lamps, wattage, etc.) is different in each system when performing color matching control a to 20f, the color temperature is the same in both systems, and the lamp type (lamp Even if the combination, wattage, etc.) are the same, the color temperature can be different for both systems.
The degree of freedom in toning control can be increased.

The other effects are similar to those of the first embodiment. In each of the embodiments described above, the fluorescent lamps of three primary colors of R, G, and B are used as the discharge lamps as the lighting load to be adjusted. However, the present invention is not limited to this. 5000K, 3000K combination, etc.) or a white fluorescent lamp with R,
The light source colors may be different by adding G and B filters. Needless to say, incandescent loads may be combined.

The toning control signal output may be any output as long as each lighting load can be continuously changed, and a DC signal, a decoding signal or the like can be considered. In the lighting device, this signal is further converted into a frequency signal or the like and controlled by frequency dimming or the like. In addition, not only the color temperature change (change on the black body locus indicated by the curve X ₁ in the CIE chromaticity diagram of FIG. 8) but also the amount of light whose illuminance increases and decreases at the same color temperature Change, R → G →
Select the most suitable specifications according to the lighting application, such as the color change locus of primary colors such as B → R (change of R → G → B → R shown by the curve X ₂ in the CIE chromaticity diagram of FIG. 8). Is possible, and the toning in the claims includes various changes as described above.

In addition, a data built-in ROM in the color matching terminal
Also, store multiple types of color change patterns as above,
A desired pattern may be selected with a DIP switch or the like. The wall switch may be wireless. Further, the change of the toning data is not necessarily changed continuously, and as shown in FIG. 10, for example, the color is discontinuous in four steps depending on the length of the operation time of the up button SW ₁ of the wall switch 13a. The temperature changes,
The color temperature may continuously change in each section.

In such a case, by making the seasons correspond to the seasons, the desired color temperature can be adjusted according to the season by a simple operation of the wall switch 13a.

[0062]

According to the lighting control device of the present invention, the color matching terminal receives the color matching control signal transmitted from the master unit and stores one of a plurality of types of color matching data stored in the memory. Since the toning data is read out and a plurality of lighting loads with different light source colors are controlled at the same time according to the read toning data, each of the plurality of lighting loads from the master unit to the toning terminal is controlled. It is not necessary to send the dimming amount data, and only the data for selecting the toning data needs to be transmitted one by one, and the structure of the transmission data for toning is simple.

Further, as the color matching operation, only the operation of changing the selection of the color matching data is necessary, and the color matching operation is easy. Furthermore, since the light adjustment of a plurality of illumination loads is performed at the same time, it is possible to prevent the fluctuation of the light color in the middle of the color adjustment.
