Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a lighting system that actively promotes control of the illuminance of an illuminated area such as a person's hand.

(Conventional technology) Illuminance control in lighting involves ensuring appropriate illuminance for the area to be illuminated, achieving necessary and sufficient lighting electricity costs (ie, power saving), blinking lights, dimming, etc. It is becoming popular for the purpose of saving labor by automatically performing operations.

Conventional lighting systems that control illuminance include a centralized control method used in large-scale lighting systems for offices, stores, etc.
The lighting equipment of each group is connected to the central control device by electrical wiring, and the lighting equipment of each group is connected to the lighting equipment of each group to determine the usage location, purpose, time, day of the week, etc. Intensive III considering schedule etc.
The dimming control is performed centrally for each group through each electrical wiring using the M device. In addition, in such a centralized control method, for example, an optical sensor 9 is installed near a window and connected to a centralized i+11'am device using electrical wiring, and the optical sensor detects external light such as sunlight near the window and inputs it into the control factor. There is also a lighting system.

Since the light sensor is connected to the light sensor using electrical wiring, special wiring work is required, and the system configuration such as the installation location of the light sensor cannot be easily changed. Since the installation location of the optical sensor 9, which is installed in a place where the illuminance can be detected, and the installation location of the lighting equipment do not necessarily correspond, management that truly corresponds to the illuminance of the illuminated area, which is important in practice, cannot be performed. Furthermore, since it is not possible to manage illuminance that truly corresponds to each place of use, it is not possible to precisely manage the illuminance of d3 and the illuminated area, so it is difficult to realize the necessary and sufficient amount of power consumption for lighting. undivided.

On the other hand, in small-scale lighting systems such as those for residential use, the necessary illuminance is determined at hand using human senses and dimming is commanded manually, making it difficult to obtain appropriate illuminance control. It is troublesome to manually adjust the brightness every time the illuminance changes.

The present invention was developed in view of the above-mentioned problems, and in addition to the advantages of centralized control, wireless control is performed using a wireless medium in response to dimming commands from the illuminance detection unit, thereby eliminating the need for wiring work and improving system performance. Changes can be made easily, and by controlling the illuminance at the illuminated area, optimal illuminance can be obtained, making it possible to save energy on the cane, and freeing people from the task of controlling illuminance intuitively. The purpose is to provide a lighting system.

In this case, each lighting device section 14 can be controlled by the same address N.

, or perform group control by setting a different address NQ for each lighting fixture section 14 separately.

Next, a method for setting the dimming state of each lighting device section 14 in the memory of the remote control section 15 will be explained with reference to the flowchart shown in FIG. Note that one remote control section 15 can handle, for example, 4
Assuming a case where the lighting fixture sections 14 of the stand are controlled separately, addresses NQ 1 to NQ 4 are respectively set for each lighting fixture section 14.

By operating , it is possible to set an arbitrary dimming value such as 30% or 80%, for example. When the settings for mode Nα1 are completed and you want to continue setting for other modes, after specifying the other mode, specify the address and perform the dimming setting in the same procedure, and then the setting is completed. When all is completed, specify the setting end button 53 to complete the setting. These dimming settings are stored in the memory of the illuminance setting section 43 of the remote control section 15 for each mode.

Next, the control operation of the lighting system of this embodiment will be explained.

First, in the centralized control, the central control device 11 sends information to each electrical wiring 12 through each electrical wiring 12 based on the usage location, purpose, and time schedule such as the time and day of the week of the lighting equipment unit 14 group connected to each electrical wiring 12. A dimming command signal with an appropriate dimming level is output for each of the 14 groups of lighting equipment units.

In each lighting device section 14, the signal reading section 31 receives a dimming command signal for centralized control that is input to the CPU 25 of the reception control unit 24 through the electrical wiring 12 (there is no input from the signal reception section 27, and the clear circuit 33 is not set), CP LJ based on the dimming command signal.
A dimming 111m signal is outputted from the output circuit 32 of 25 to the dimming unit 22 of the appliance main body 23, and the dimming unit 22 is caused to dim the light source 21.

With such centralized control, illuminance can be managed according to the time zone of daily life, such as work start time, break time, work end time, etc., using a time schedule, for example, and power saving can be achieved.

On the other hand, if you want to set the illuminance of the lighting fixture section 14 using an operation mode stored in the remote control section 15 separately from the centralized control 1I11, if you specify, for example, mode Nα1 on the remote control section 15, the mode will be stored in the memory of mode Nα1. The dimming setting contents of each address No. 1 to 4 are transmitted through the illuminance comparison and determination section 42 as a dimming command signal from the signal transmitting section 44 via a wireless medium such as infrared rays or radio waves. Regarding the transmission of this dimming command signal, for example, address No. 1 to
4, and each address No. 1 to No. 4 can be heard in each dimming command signal.

In each lighting fixture section 14, the signal receiving section 27 receives a dimming command signal transmitted from the remote control section 15 via a wireless medium, and
Send to PU25. All the signals received by the signal receiving part 27 are transmitted to the signal reading part 31 of this CP Ll 25, but the dimming command signal of an address number other than the address Nα set in the address setting part 26'c is input. The dimming command signal is not accepted even if the address No. set in the address setting section 26 is input, and the dimming command signal is accepted and input. At this time, the dimming command signal from the concentrated 1111 [1 device 11 that is input to the signal reading unit 31 through the electric wiring 12 is not accepted. Then, the signal receiving section 27 (remote control section 15) received by the signal reading section 31
Based on the dimming command signal from the output circuit 32 of the CP LJ 25, a dimming control signal is output to the dimming unit 22 of the appliance main body 23, and the dimming unit 22 is caused to dim the light source 21. For example, the light source 21 is turned on in the fixture body 23 to which an ON dimming command signal is input, and the light source 21 is turned off in the fixture body 23 to which an OFF dimming command signal is input, and a dimming command for 50% dimming is issued. Instrument main body 23 into which the signal is input
Now, the light source 21 is turned on with 50% dimming.

Further, if there is an address Nα set to automatic dimming, the lighting fixture section 14 of that address No. is subjected to intransitive light control. This automatic light control fiIIwJ! The 11 works are shown in the flowchart in Figure 5.

The illuminance detection section 41 of the remote control section 15 detects the illuminance by receiving light from the light source 21 and external light (sunlight, light from nearby lighting, etc.), and sends the detected illuminance value to the illuminance comparison and determination section 42. The illuminance comparison and determination section 42 compares the detected illuminance value with the illuminance setting section 4.
3, and if it is determined that illuminance correction is necessary, the automatic brightness increase (i
T! Outputs a dimming command signal for turning on the light (including turning it on from the j lamp state) or dimming (including turning it off). For example, when the illuminance due to outside light is high in the daytime, the illuminance value detected by the illuminance detection unit 41 will be higher than the target illuminance value, so in order to lower the illumination intensity from the light source 21, dimming of the automatic dimming is performed. In addition, when the illuminance due to outside light decreases in the evening, the detected illuminance value becomes lower than the target illuminance value, so in order to increase the illuminance of the light source 21, a dimming command signal for increasing the brightness of automatic dimming is output. Output. Note that if it is determined that the illuminance is appropriate, the dimming command signal will not be output, but a dimming command signal that instructs the current status to be maintained may be output.

The dimming command signal for dimming or increasing the automatic dimming output from the illuminance comparison/judgment section 42 is transmitted from the signal transmitting section 44 via a wireless medium.

Then, in the lighting equipment section 14 set to automatic dimming, when the address numbers match and a dimming command signal for automatic dimming or brightness increase is received, the CPU 25 controls the dimming command signal based on the dimming command signal. controls the dimming 1 nit 22, and the light source 2
1 to dim or increase its brightness.

In this way, the remote control unit 15 detects the illuminance, and when the detected illuminance value reaches the target illuminance value, it transmits a dimming command signal for automatic dimming or brightening, and the automatic dimming is set. The lighting equipment section 14 controls the light source 21 based on the dimming command signal.
Performs dimming. Therefore, for example, by setting the lighting device section 14 above the desk surface where the user works to automatic dimming and placing the spider section 15 on the desk surface, appropriate illuminance at hand can always be obtained.

Also, depending on the situation, the mode specifying section 54 of the remote control section 15
Select the mode from. That is, for example, if a certain lighting fixture section 14 no longer needs to be lit, the lighting fixture section 1
By selecting each preset mode, such as selecting mode Nα in which lights are turned off in No. 4 using the remote controller 15, lighting can be performed to suit the situation.

On the other hand, when each lighting equipment section 14 is in a dimming state set in a certain mode, changes in the usage environment, the density of work, the atmosphere created, the worker's mood, physical condition, age, eye condition, preference, etc. Therefore, if you want to manually set the dimming of a certain lighting fixture section 14 individually, first specify the address number of the lighting fixture section 14 you want to adjust using the remote control section 15, and then set the dimming state using the dimming specifying section 58. Specify. For example, if you want to adjust the dimming of the lighting fixture section 14 at the address Nα1 that is in the lighting state, the address No. of the remote control section 15
, 1, and then operate the dimming control 65 to set the manual mode dimming command signal to address N.
o, 1 from the remote control unit 15, and the CPU 2 of the lighting fixture unit 14 of the corresponding address No. 1
At step 5, the dimming command signal is accepted, and the dimming unit 22 is controlled to dim the light source 210. This manual setting takes priority even if automatic dimming is set by specifying the mode number on the remote controller 15, and can be set to turn on, turn off, increase brightness, dim, 50% brightness, and automatic brightness. Each can be set. In this case, the illuminance can be adjusted while checking it from the user's location.

Furthermore, by adjusting the target illuminance value with the illuminance setting section 43 of the remote control section 15, the illuminance at hand can be adjusted by dimming or increasing the light 'm21 of the lighting fixture section 14 which is set to automatic dimming. can.

In addition, by operating the all-off button 63 of the remote control unit 15, all the lighting equipment units 14 at addresses No. 1 to 4 can be turned off.
is turned off.

Furthermore, if the mode is designated again using the mode designation section 54 of the remote control section 15, the manual setting or all lights-out is canceled, and dimming control corresponding to the designated mode is performed.

In addition, when performing group υ control on several lighting equipment sections 14 as one group, the same address Na is set for each group, but when it is desired to change the group configuration, the address setting section 26 of each lighting equipment section 14 This can be easily done by simply changing the address number setting.

In addition, when you want to change the illuminated area to obtain the optimum illuminance by changing your seat, etc., you can bring the remote control unit 15 containing the illuminance detection unit 41 to the changed location of the illuminated area.
: The changed optimal illuminance of the illuminated area is shown. Note that if the lighting fixture section 14 corresponding to the changed illuminated section is controlled by central control and the illuminance is not the desired illuminance, the desired illuminance is set by manual setting as described above.

Further, when a gas leak, fire, earthquake, etc. is detected by a detector, a special mode signal is output from the central control device 11 to each lighting device 14 through the electrical wiring 13.

This signal is input to the clear circuit 33 of the CPU 25 of the lighting equipment section 14 to clear the operating state of the CP tJ 25, that is, the operating mode controlling the dimming unit 22, and at the same time, the signal ] - input as a control signal to the unit 22 to turn on the light source 21 in a special mode such as blinking.

As described above, by using both the centralized control method and the wireless control method, in addition to the advantages of the centralized control method that allows special settings such as time schedule control and emergency settings, remote control section 15 having 41;
There is no need for special wiring work to connect the illuminance detection section 41, the remote control section 15 that detects the illuminance detection section 41 can be moved to any location, and the illuminance can be managed separately for the lighting equipment section 14, making it possible to change the system. In addition, the installation location of the remote control unit 15 having the illuminance detection unit 41 and the lighting equipment unit 1 can be easily adjusted.
Since the installation locations in 4 correspond to each other, it is possible to precisely control the illuminance of the illuminated area, which is actually important.Furthermore, since the illuminance of the illuminated area can be precisely controlled, the electricity bill for lighting can be reduced to the necessary and sufficient level. Achievement of power saving is fully achieved. Moreover, since the illuminance can be adjusted automatically in response to sudden changes in the use environment and conditions such as external light, humans are freed from the task of managing illuminance intuitively.

In addition, the lighting equipment section 14 is controlled by the remote control section 15 rather than centrally controlled.
By prioritizing commands from the remote controller 15, illuminance can be set at will, and by prioritizing special settings over commands from the remote control unit 15, illuminance can be set reliably in emergencies.

〔Effect of the invention〕

According to the present invention, by using both a centralized control method for the lighting equipment section and a wireless control method in which the lighting equipment section and the remote control section having the illuminance detection section are connected via a wireless medium, the lighting equipment section and the illuminance detection section are provided. There is no need for special wiring work to connect to the remote control section, and system changes such as changing the location of the remote control section, changing from centralized control of the lighting equipment section to individual control using the controller section, and vice versa are possible. Changes can be made easily, and by placing the remote control unit on the illuminated area where you want to obtain the appropriate illuminance, such as the desk surface where you work, you can match the illuminance detection unit of the remote control unit with the illuminated area. This makes it possible to perform illuminance management that truly corresponds to the illuminance of the illuminated area, which is actually important, and obtain the optimum illuminance.Furthermore, since the illuminance of the illuminated area can be managed in detail, it is possible to achieve sufficient power savings. Moreover, since the illuminance can be adjusted automatically in response to sudden changes in the usage environment and conditions, such as changes in external light, humans can be freed from the task of managing illuminance intuitively.
