In the figure, 1 is a centralized control device for centrally controlling the entire lighting of a building or the like, 2 is electrical wiring for centralized control, 3 is electrical wiring for special setting, and electrical wirings 2 and 3 are for each group. A plurality of lighting fixtures 4 such as a ceiling lamp are connected to each of the electric wirings 2 and 3. Further, a plurality of remote control units 5 are provided corresponding to each lighting fixture unit 4.
[0003]
The luminaire unit 4 includes a light source 6 such as a fluorescent lamp, a ballast unit or a switch for turning on the light source 6, and a light control unit 7 having a light control circuit or a volume for performing light control. 8 and a reception control unit 9 that receives the dimming command signal transmitted from the remote control unit 5 through a wireless medium and controls the dimming unit 7, and is configured as an adapter for the instrument body 8. The reception control unit 9 continuously modulates light from the bright light to the extinction.
[0004]
The remote control unit 5 compares the illuminance detection unit 10 with the illuminance comparison determination unit 11 that compares the detected illuminance value detected by the illuminance detection unit 10 with the target illuminance value, determines illuminance correction, and outputs a dimming command signal. An illuminance setting unit 12 having various setting buttons for setting illuminance and having a memory for storing illuminance setting contents, and a dimming command signal output from the illuminance comparison / determination unit 11 are transmitted to the luminaire unit 4 by a wireless medium. The signal transmitting unit 13 and the power source 14 are small, portable and can be installed on an illuminated part such as a desk surface.
[0005]
Next, the operation will be described.
The illuminance detection unit 10 of the remote control unit 5 receives light from the light source 6 and external light to detect illuminance, and sends the detected illuminance value to the illuminance comparison determination unit 11. The illuminance comparison / determination unit 11 compares the detected illuminance value with the target illuminance value set in advance by the illuminance setting unit 12, and if both values do not match and it is determined that illuminance correction is necessary, automatic adjustment is performed. Output light intensity or current dimming command signal. The signal transmission unit 13 transmits this dimming command signal to the luminaire unit 4. The reception control unit 9 of the luminaire unit 4 receives this dimming command signal, controls the dimming unit 7 based on this signal, and dims the light source.
[0006]
In this way, the illuminance is detected by the remote controller 5 and the dimming command signal for automatic dimming or dimming is transmitted until the detected illuminance value reaches the target illuminance value. The unit 4 performs dimming of the light source 6 based on the dimming command signal. For this reason, for example, an appropriate hand illuminance can always be obtained by setting the luminaire unit 4 installed above the desk surface where the work is performed to automatic light control and arranging the remote control unit 5 on the desk surface.
[0007]
[Problems to be solved by the invention]

[0014]

[0015]
Next, the operation will be described.
First, the setting operation to the automatic light control lighting device 22 by the setting device 21 will be described. After the automatic light control lighting device 22 is installed, the setting button 28 and the transmission button 29 of the setting device 21 are operated, and a light control output command is transmitted to the automatic light control lighting device 22 by the communication means 27. The automatic light control lighting device 22 receives a command by the communication means 25, and the lighting controller 23 outputs a light control signal to the lighting fixture 26 based on the command. For example, the luminaire 26 is turned on with a dimming output of 100%, 50%, and 20%. In each dimming output, the illuminance value detected by the illuminance detection unit 20 of the setting device 21 is transmitted to the automatic dimming illumination device 22 by the communication means 27.
[0016]
The illumination controller 23 of the automatic light control illumination device 22 stores the illuminance value received by the communication means 25 and the detected voltage of the illuminance sensor 24 at that time. Then, the relationship between the illuminance [lx] and the sensor voltage [V] shown in FIG. 2 is created and held by interpolating between the measurement points by linear approximation based on the data of these three lighting patterns. This relationship diagram may be in the form of an approximate expression.
[0017]
After that, when the illumination controller 23 receives a command from the outside such as the setting device 21 through the communication unit 25 and the illumination output is designated by the illuminance [lx], the designated illuminance [lx] is referred to the relationship diagram. The output of the dimming signal is adjusted so that the illuminance sensor voltage falls within the range, and the lighting fixture 26 is turned on with the specified illuminance.

[0018]
Embodiment 2. FIG.
In the first embodiment, the communication between the setting device 21 and the illumination controller 23 is only one-way communication from the setting device 21 to the illumination controller 23, but bidirectional communication may be performed.

The setting device 21 includes an illuminance detection unit 20 that detects illuminance, a transmission unit, and a reception unit, and starts setting to the communication controller 33 that performs bidirectional communication with the automatic light control illumination device 22 and the illumination controller 23. From a start button 34, a buzzer 35 for notifying setting completion, a transmission button 29 for transmitting an illuminance value and a dimming output value, a display means 30 comprising an LCD, an LED, etc., a microcomputer 31, and a power supply circuit 32 Composed.

The automatic light control illumination device 22 is configured in the same manner as in the first embodiment.
[0020]
Next, the operation will be described.
The setting operation to the automatic light control lighting device 22 by the setting device 21 will be described with reference to FIG. When the start button 34 of the setting device 21 is pressed, the setting device 21 transmits a command for turning on at a dimming output of 100% to the automatic dimming illumination device 22. The automatic light control lighting device 22 receives a command by the communication means 25, and based on this command, the lighting controller 23 outputs a dimming signal to the lighting fixture 36, and adjusts the lighting fixture 36 to the designated output (step S1). . After this adjustment is completed, an adjustment completion command is transmitted to the setting device 21 (step S2).
[0021]
Upon receiving the setting completion signal, the setting device 21 transmits the illuminance value detected by the illuminance detection unit 20 to the illumination controller 23 (step S3). The illumination controller 23 stores the received illuminance value and the detected voltage of the illuminance sensor 24 at that time (step S4). Next, the illuminance value and the detection voltage at the dimming output of 80% are stored in the above procedure.
[0022]
In this way, the dimming output is changed in the range of 0% to 100%, and the illuminance value and the detection voltage are stored a predetermined number of times. The illumination controller 23 determines the relationship between the illuminance [lx] and the sensor voltage [V] from the measured data. A figure is created and held in the lighting controller 23.
When the above procedure is completed, the setting device 21 notifies the end of the setting using the buzzer 35 and the display means 30 such as an LED (step S5).
[0023]
Thereafter, when the illumination controller 23 designates the illumination output via the communication means 25 as the illuminance [lx], the illumination controller 23 refers to the relationship diagram and adjusts the dimming signal so that the illuminance sensor voltage corresponds to the designated illuminance [lx]. And the lighting fixture 26 is lit at a specified illuminance.
Therefore, the setting operation can be performed more easily.
