After the lighting control device 21 is installed, the daylight level for setting the dimming level is set.

At this time, the position of the lighting unit 2 in the illumination space 1,
Since the daylight utilization rate varies depending on the direction and size, it is preferable to measure the daylight utilization rate for each construction site before setting the daylight level. In the measurement of the daylight utilization rate, the amount of daylight detected by the optical sensor 23 is read from the display unit 25 at regular intervals, and at the same time, the illuminance near the daylighting unit 2 of the illumination space 1 by daylight is measured by an illuminometer. .

The main operation panel 11 controls the blinking of the lighting equipment 3 of each blinking control block 4 by time schedule control. In this time schedule control, lighting control is performed at the start of working hours,
Turn off the lights at the end of working hours. Then, it is assumed that all the lighting fixtures 3 are turned off before the start of working hours, and in this state, even if the optical sensor controller 22 of the lighting control device 21 is powered on and is in an operating state. The lighting fixtures 3a for dimming control are kept in the off state without being dimmed.

At the start of working hours, a transmission signal including address data and lighting control data of each control terminal 13 is transmitted to the transmission line 12 of the main operation panel 11. Each control terminal device 13 receives the lighting control data of its own address transmitted to the transmission line 12, and turns on the power of all the lighting fixtures 3 in the corresponding blinking control block 4. As a result, among the lighting fixtures 3, all the blinking control lighting fixtures 3b are turned on, and the dimming control lighting fixture 3a performs control based on the dimming signal from the optical sensor controller 22.

A dimming level corresponding to the amount of daylight entering the illumination space 1 from the lighting unit 2 detected by the optical sensor 23 is calculated. That is, if the daylight amount is lower than the lower limit daylight level L2, the dimming level is set to 100%, and if the daylight amount is in the range between the lower limit daylight level L2 and the upper limit daylight level L1, the dimming level corresponding to the daylight amount is adjusted. The light level is calculated, and if the amount of daylight is higher than the upper limit daylight level L1, the dimming level is set to x%.

Corresponding dimming signals (PWM signals) are formed, and these dimming signals are output from the output buffers 29 to the dimming control lighting units of the dimming control lighting fixtures 3a of the dimming control blocks 5, respectively. It

As a result, in the dimming control lighting unit of each dimming control lighting device 3a, the lighting state of the lamp is dimmed at the dimming level based on the dimming signal input from the optical sensor controller 22.

Power can be achieved.

Further, at the end of working hours, a transmission signal including address data and extinguishing control data of each control terminal 13 is transmitted to the transmission line 12 of the main operation panel 11. Each control terminal device 13 receives the lighting control data of its own address transmitted to the transmission line 12, and turns off the power of all the lighting fixtures 3 in the corresponding blinking control block 4. As a result, all of the dimming control lighting device 3a and the blinking control lighting device 3b of the lighting device 3 are turned off.

It is necessary to perform the measurement, but by providing the storage unit 31, it can be performed by one setter.

When measuring the daylight utilization rate, first, the configurator goes to the installation location of the optical sensor controller 22 and operates the memory start switch, and then the configurator goes to the illumination space 1

As a result, the photosensor controller 22 samples and stores the amount of daylight detected by the photosensor 23, for example, every 10 minutes, and the setter measures the illuminance approximately at the time when the amount of daylight is stored.

After the measurement is completed, the setter goes to the place where the optical sensor controller 22 is installed, operates the read start switch, and causes the display unit 25 to sequentially display the daylight amount stored in the storage unit 31.

Since a system is provided and the dimming level corresponding to each output system is obtained by the dimming level calculation unit, dimming control can be finely performed at each place in the illumination space where the amount of daylight is different.

According to the illumination control device of the fifth aspect, in addition to the effect of the illumination control device of the first aspect, the dimming signal output from the dimming signal output section is input. By providing a lighting fixture that performs dimming, a lighting environment can be dimmed so that a comfortable lighting environment can be obtained and power can be saved.

According to the illumination control system of claim 6, the illumination control device according to any one of claims 1 to 4 can be easily incorporated into the system for controlling the blinking of the luminaire by the main operation panel. The dimming of the lighting fixture can be controlled.

According to the illumination control system of claim 7, in addition to the effect of the illumination control system of claim 6,
Even in a system that controls blinking of a lighting fixture through a control terminal connected to a transmission line of the main operation panel, the lighting control device can be easily incorporated to control dimming of the lighting fixture.

According to the lighting control system of claim 8, in addition to the effect of the lighting control system of claim 6 or 7, it has a plurality of lighting fixtures installed in the lighting space,
Among these lighting devices, the lighting control device controls the lighting device installed on the side of the daylighting part where daylight is illuminated in the lighting space, so that an efficient and comfortable lighting environment can be obtained and power saving can be achieved.

According to the illumination control system of claim 9, in addition to the effect of the illumination control system of claim 8,
Since a plurality of lighting devices are divided into a plurality of blinking control blocks and controlled by the main operation panel, and at least one lighting device in at least one blinking control block is controlled by the lighting control device, dimming is required. Dimming control is possible only for lighting equipment.

According to the lighting control system of the tenth aspect, in addition to the effect of the lighting control system of the eighth or ninth aspect, the dimming control lighting fixture is used only for the lighting fixture controlled by the lighting control device. Since the lighting fixtures for blinking control are used in addition to the lighting fixtures for dimming control, the system can be constructed at low cost.
