Description

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

(Conventional technology) Controlling the illuminance of lighting is necessary to ensure appropriate illuminance for the area to be illuminated, to reduce electricity costs for lighting as much as necessary, to save electricity, to turn lights on and off, etc. It is becoming popular for the purpose of saving labor by automatically performing operations such as dimming.

Conventional lighting systems that control illuminance include centralized control methods used in large-scale lighting systems such as offices and stores, which control several lighting fixtures at once.
The lighting equipment of each group is connected to the central control device by each electrical wiring, and the lighting equipment of each group is connected to the location, purpose, time, day of the week, etc. In consideration of schedule calls, etc., dimming control is performed centrally for each group through each electrical wiring using a central control device. In addition, in such a centralized control system, for example, a light lens is installed near a window and connected to the central control device by electrical wiring, and the light sensor detects external light such as sunlight near the window and uses it as a control factor. There is also a lighting system built into the interior.

On the other hand, some small-scale lighting systems, such as those for residential use, are configured to allow dimming of lighting equipment to be controlled remotely from a remote controller.

Moreover, the installation location of the light sensor, which is usually installed in a place where the illuminance of sunlight can be detected, such as near a window, does not necessarily correspond to the installation location of the lighting equipment, so it is difficult to accurately match the illuminance of the illuminated area, which is actually important. It is not possible to manage the individual lighting fixtures within the group, and since it is collectively managed for each group, it is not possible to manage individual lighting fixtures within the group.

Furthermore, since detailed control is not possible for each location of use, and since it is not possible to truly control the illuminance of the illuminated area, it is not possible to sufficiently realize the necessary amount of electricity costs for lighting, that is, power savings. .

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 commands are issued by hand + operation, making it difficult to obtain appropriate illuminance control. For example, it is troublesome to manually adjust the brightness each time the illuminance due to outside light changes.

In addition, in a lighting system using Teru GTNZA, basic settings for the illuminance level are made at the time of system configuration, but it is desirable to be able to manually set it depending on the usage situation, and furthermore, it is possible to make special settings in case of an emergency. or desirable.

The present invention was made in view of the above-mentioned problems, and by using a wireless medium for dimming commands and eliminating the need for wiring, the system can be easily changed and the system configuration can be made small and inexpensive. In addition, by controlling the illuminance at the illuminated area, it is possible to obtain the optimal illuminance and save power, freeing people from the task of controlling illuminance intuitively.Furthermore, basic settings of the illuminance level and manual The object of the present invention is to provide a lighting system that allows settings and special settings, and the invention of claim 2 also aims to provide a lighting system that allows basic settings, manual settings, and special settings to be set at a location suitable for the purpose of use.

Bright lights in section 11 (100% lighting)
A basic mode of light and light off, or a basic mode of bright light, dimming, and light off is set, and a basic mode of continuously variable illuminance is set for the lighting equipment section 11 in a place that requires advanced illuminance management. The manual mode and special mode, which will be described later, are controlled in priority order over the basic mode. Therefore, this CPU 16 includes a receiver 1i+control unit 1.
5 address Na, for example, an address setting section 17 for setting one from address No. 1 to 4, a signal receiving section 18 for receiving a dimming command signal transmitted via a wireless medium, a power supply section 19, etc. For example, a monitor 20 is connected to display two lamps, one for increasing the brightness and one for decreasing the brightness, on the outside of the device and displaying that the brightness is being adjusted to increase or decrease the brightness toward a target dimming value. The address setting section 17 is composed of, for example, a switch, and the selector of the switch is made to face the surface of the lighting equipment section 11 so that the address number can be easily selected and set. Infrared rays and radio waves are used as wireless media, and the drawing shows a photodiode that receives infrared rays.

On the other hand, the remote control unit 12 is small enough to be portable and not get in the way even when placed on an illuminated area such as a desk surface, and has a photoelectric conversion element such as a CCD that can detect illuminance. an illuminance detection section 21 that compares the detected illuminance value detected by the illuminance detection section 21 with a target illuminance value, determines illuminance correction, and outputs a dimming command signal.
, an illuminance setting section 23 as a manual setting section having various setting buttons for illuminance setting, a signal transmitting section 24 that transmits a dimming command signal outputted from the illuminance comparison and determination section 22 via a wireless medium, etc. It is equipped with a power source 25 such as a solar battery or connected to a commercial power source via an AC adapter. Note that the wireless medium transmitted by the signal transmitter 24 includes infrared rays and radio waves, and a light emitting diode is shown in the drawing.

[, Fig. 2 shows the illuminance setting section 23 of the remote control section 12.
- In the example shown, 31 is a setting specifying section, which includes a setting button 32 for specifying the start of illuminance setting and a setting end button 33 for specifying the end of illuminance setting. Also, 3
Reference numeral 4 denotes a mode specifying section, which includes mode numbers 1 to 5 buttons 35a to 35e for specifying the dimming state of the lighting fixture section 11. Furthermore, 36 is an address designation section, which includes buttons 37a to 37d of address numbers 1 to 4 for designating the lighting fixture section 11 to which the address number has been set. Further, numeral 38 denotes a dimming designation section, which includes an on button 39, an on button 40, a 41.50% dimming button 42 for automatic dimming, a dimming button 43, a brightness increase 44, and a dimming 45, respectively.

It has a monitor that displays that the brightness is being adjusted to increase or decrease the brightness.

Further, as shown in FIG. 1, the lighting equipment section 11 is connected to a special setting section 51 by electric wiring 52, and this special setting section 51 uses a detector to detect emergency situations such as gas leaks, fires, and earthquakes. Then, a special mode signal is output to the C lighting fixture section 11 through the electric wiring 52. Then, in the lighting equipment section 11, the special mode signal is input to the clear circuit 16a of the CPU 16 to clear the operating state of the CPU 16, and at the same time, the special mode signal is input to the dimming unit 14 as a control signal to 13 is turned on in a special mode such as blinking. In addition, when there are a plurality of lighting equipment parts 11, the electric wiring 52 may be connected only to the necessary lighting equipment parts 11 to perform the special mode.

In addition, in this lighting system, it is possible to control the dimming of a plurality of lighting fixtures 11 with one remote control unit 12. For example, if there are four lighting fixtures 11, the dimming of each of the lighting fixtures 11 can be controlled. When controlling separately, a different address No. 1 to /I is set in the address setting section 17 for each lighting device section 11.
In addition, when there are multiple lighting equipment sections 11 and the dimming of some of the lighting equipment sections 11 is performed at once, that is, when the plurality of lighting equipment sections 11 are group controlled as one group. , the lighting equipment section 11 of those groups
to the same address number.

Next, a method for setting the dimming of each lighting device section 11 will be explained with reference to the flowchart of FIG. 3. In addition, as mentioned above, it is assumed that there are four or more lighting equipment units 11, and addresses Nos. 1 to 4 are set respectively.

Press the setting button 32 of the illuminance setting section 23 of the remote control section 12,
The mode specifying section 34 selects and specifies the mode number, and the address specifying section 36 selects and specifies the address N of the lighting equipment section 11.
o is selected and specified, and the dimming state is specified using the dimming specifying section 38. For example, in the specified state of mode Nα1, after specifying address No. 1, the lighting fixture section 11 of address No. 1 is set to turn on by specifying the A button 39, and then address No. 2 is set to turn on. After specifying, the lighting fixture section 11 of address No. 2 is set to off by specifying the off button 40, and then the address No. 2 is set to off.

After setting 3, by specifying the automatic dimming box 41, the lighting fixture section 11 at address No. 3 is set to automatic dimming,
Continuously, after setting the address No./I, the lighting device section 11 at address No. 4 is set to 50% dimming by specifying the 50% dimming button 42. In addition, after specifying the A button 39, the off button 40, and the 50% dimming button 42, or directly, press the brightness increase button 44 or the dimming button 4.
By operating 5, an arbitrary dimming value such as 30% or 80% can be set. And mode N.

After completing the settings for 1, continue with 4 for other modes.
When making settings, after specifying other modes,
Specify the address, perform the dimming setting in the same manner, press ``I'', and when all settings are completed, specify the setting end button 33 to complete the setting. These dimming settings are stored in a memory to the right of the illuminance setting section 23 of the remote control section 12 for each mode.

Next, a description will be given of the illuminance control operation performed by the lighting system in which the dimming setting has been performed as described above.

For example, when mode Nα1 is designated with the remote controller 12, each address Nα stored in the memory of mode No. 1 is
Each of the dimming settings α1 to α4 is transmitted as a dimming command signal through the illuminance comparison and determination unit 22 from the signal transmitting unit 24 via a wireless medium such as infrared rays or radio waves. The transmission of this dimming command signal is performed, for example, in the order of addresses Nα1 to Nα4, and each of the dimming command signals includes each address No. 1 to 4.
are each proclaimed.

In each lighting fixture section 11, the signal receiving section 18 receives a dimming command signal transmitted from the remote control section 12 via a wireless medium, and c
Send to p U 16. All signals received by the signal receiving section 18 are transmitted to the CPU I6, but even if a dimming command signal with an address number other than the address number set in the address setting section 17 is input, it will not be accepted. Only when the address No. set in the address setting section 17 is input, the dimming command signal is accepted and input.

Then, the CPU 16 controls the light control unit 14 in accordance with the light control command signal to perform light control of the light source 13. For example, the light source 13 is turned on in the lighting fixture section 11 to which the ON dimming command signal is input, and the light source 13 is turned off in the lighting fixture section 11 to which the A-f dimming command signal is input, and the light is dimmed by 50%. In the lighting equipment section 11 to which the dimming command signal is input, the light source 1
Turn on 3 with 50% dimming.

Further, if there is an address No. set to automatic dimming, the lighting fixture section 11 of that address No. is automatically dimmed. This automatic light control control operation is shown in FIG.

The illuminance detection section 21 of the remote control section 12 detects the illuminance by receiving light from the light source 13 and external light (sunlight, light from nearby lighting, etc.), and sends the detected illuminance value to the illuminance comparison and determination section 22. The illuminance comparison and determination section 22 compares the detected illuminance value with the illuminance setting section 2.
3, and if it is determined that illuminance correction is necessary, the automatic brightness will be increased (including turning on from off) or dimming (including turning off). Emit a light command signal. For example, when the illuminance due to outside light is high in the daytime, the illuminance value detected by the illuminance detection unit 21 will be higher than the target illuminance value, so in order to lower the illumination intensity from the light source 13, the automatic dimming is adjusted. outputs a command signal,
Furthermore, when the illuminance due to external light decreases in the evening, the detected illuminance value becomes lower than the target illuminance value, so a dimming command signal for increasing the brightness of automatic dimming is output in order to increase the illuminance of the light source 13. 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 22 is transmitted from the signal transmitting section 24 via a wireless medium.

Then, in the lighting equipment unit 11 set to automatic dimming, when the address numbers match and a dimming command signal for automatic dimming or brightness increase is received, the CPU 16 controls the lighting equipment based on the dimming command signal. controls the light control units 1 to 14 and dims or increases the brightness of the light source 13.

In this way, the remote control unit 12 detects the illuminance, and transmits a dimming command signal for dimming or increasing the intransitive light until the detected illuminance value reaches the target illuminance value, and the illuminance set to automatic dimming is transmitted. In the fixture section 11, the light source 13 is dimmed based on the dimming command signal. Therefore, for example, by setting the lighting device section 11 above the desk where the worker works to automatic dimming and placing the remote control section 12 on the desk surface, appropriate illuminance at hand can always be obtained.

Also, depending on the situation, the mode specifying section 34 of the remote control section 12
Select the mode from. That is, for example, if a certain lighting fixture section 11 no longer needs to be lit, the lighting fixture section 1
By selecting each preset mode, such as selecting mode No. 1 in which the lights are turned off using the remote controller 12, lighting can be performed to suit the situation.

On the other hand, when each lighting equipment section 11 is in a dimming state set in a certain mode, changes in the usage environment, the density of the work, the atmosphere created, the worker's mood, physical condition, age, eye condition, etc. If you want to manually set the dimming of a certain lighting fixture section 11 individually based on your preference, first specify the atres Nα of the lighting fixture section 11 you want to adjust using the remote control section 12, and then set it using the dimming specifying section 38. Specify the dimming state. For example, the lighting fixture section 1 of address No. 1 which is in the lighting state
If you want to adjust the dimming of 1, specify the address No. 1 on the remote controller 12 and then operate the dimming control 45, so that the dimming command signal for manual mode dimming is the same as the address No. 1. is transmitted from the remote control unit 12 to
CP of the lighting fixture section 11 of the corresponding address No. 1
The dimming command signal is accepted by U 16, and the dimming unit 1
4 to dim the light source 13. This manual setting can be performed with priority even if the basic mode of automatic dimming is set by specifying mode N0 on the remote control unit 12, and can be set to turn on, turn off, increase brightness, dim, 50% dimming, and automatic dimming. 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 23 of the remote control section 12, the illuminance at hand can be adjusted by dimming or increasing the light source 13 of the lighting equipment section 11 which is set to automatic dimming. .

In addition, by operating the all-off button 43 of the remote control section 12, all the lighting equipment sections 11 are turned off.

Furthermore, if the mode is designated again using the mode designation section 34 of the remote control section 12, the manual setting or all lights-out is canceled and the dimming a1 control corresponding to the designated mode is performed.

In addition, when performing group control on several lighting equipment sections 11 as one group, the same address N0 is set for each group, but when it is desired to change the configuration of the group, each lighting equipment section 1
The address setting section 17 of No. 1 can be used to easily change the setting of the address number.

In addition, when you want to change the illuminated area to obtain the optimum illuminance due to changing your seat, etc., you can change the illuminated area by taking the remote control unit 12 containing the illuminance detection unit 21 to the changed location of the illuminated area. The optimum illuminance of the illuminated area can be obtained. Note that if the lighting fixture section 11 corresponding to the changed illuminated section is not set to automatic dimming, it is set to automatic dimming by manual setting as described above.

Further, when a gas leak, fire, earthquake, etc. is detected by the detector, a special mode signal is output from the special setting section 51, and the CP Ll of the lighting equipment section 11 to which the electric wiring 52 is connected is output.
The clear circuit 16a of the CPU 16 clears the operating state of the CPU 16, that is, the basic mode or manual mode that controls the light control unit 14, and at the same time clears the operating state of the CPU 16, such as the basic mode or manual mode that controls the light control unit 14. Lights up in mode.

As described above, by connecting the lighting device section 11 and the remote control section 12 using a wireless medium, there is no need for special wiring work, and the address N of the lighting device section 11 can be changed.

The dimming control group can be easily changed by simply switching the dimmer control group, and the remote control section 12 containing the illuminance detection section 21 can be moved to any location. Can be done cheaply. Furthermore, since the installation location of the remote control section 12 having the illuminance detection section 21 corresponds to the installation location of the lighting equipment section 11, management can be performed that truly corresponds to the illuminance of the illuminated area, which is of practical importance. ,
It is also possible to manage each individual lighting fixture section 11 within the group. Furthermore, since the illuminance of the illuminated area can be controlled in detail, the cost of electricity for lighting, that is, power saving, can be sufficiently achieved on the order of -1 minute. 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 based on their senses.

By the way, when designing lighting equipment, designing room lighting, and configuring the lighting system for the lighting equipment section (= J time, etc.), it is important to consider or try out the purpose of lighting, the density of work, the atmosphere to be created, the preferences of workers, etc. By configuring the basic settings of the lighting fixture section 11, for example, the lighting fixture section 11 in places where rough illuminance management is fine can be set to the basic mode of bright light (100% lighting) and lights off, or the basic mode of bright light, dimming, and lights out. By setting the basic mode of continuously variable illuminance in the lighting equipment section 11 of the place that requires advanced illuminance management, the basic mode of bright light and light off, or bright light, dimming, and light off can be set to The circuit configuration of the reception control unit 150 of the fixture section 11 is simple, the dimming circuit and dimming volume of the dimming unit 14 can be simply switches, and the circuit configuration of the remote control section 12 is also simple, making it possible to simplify the configuration of the lighting system. It is simple and inexpensive, and the basic mode of continuously variable illuminance allows fine-grained illuminance management, ensuring eye health, improving work efficiency, and saving power.

In addition, by giving priority to the manual mode over the basic mode of illuminance level set in the lighting equipment section 11, the illuminance can be set arbitrarily, and by giving priority to the special mode over the basic mode and manual mode, it is possible to set the illuminance in an emergency, etc. You can reliably set the illuminance.

In addition, the basic setting of the illuminance level, which does not change frequently, is set in the lighting fixture section 11 when configuring the system, and the manual setting section for manually setting the illuminance level is installed in the remote control section 12 at hand. Setting section 5
1 is connected to the lighting equipment section 11 (or the remote control section 12), so that it can be installed at a location suitable for setting each illuminance level, simplifying the system configuration, facilitating manual settings, and ensuring reliability in the event of an emergency. can get.

In addition, in the above embodiment, the special setting section 51 and the lighting equipment section 11
However, the special setting section 51 and the remote control section 12
When the special mode signal is generated, the remote control section 12
The lighting fixture section 11 may be set to a special mode through the above.

The remote controller 12 also displays changes in the situation (for example, door opening/closing, sound, presence/absence, visitor, push button, etc.).
A situation setting unit that sets the illuminance level (manual setting) based on the information may be connected.

In addition, when performing group control on a plurality of lighting equipment sections 11, if it is assumed that the group will not be changed, only the light source 13 and the dimming unit 14 can be controlled for the plurality of lighting equipment sections 11 on the right. one reception control unit 15
may be shared.

Further, on a large floor such as an office or a store, a plurality of remote control units 12 may be used together, and each remote control unit 12 may control a plurality of lighting equipment units 11 for each predetermined location.

〔Effect of the invention〕

The system configuration can be small-scale and inexpensive. Also,
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, making it practically unnecessary. Illuminance management that truly corresponds to the illuminance of the illuminated area can be performed, and optimal illuminance can be obtained.

Furthermore, since the illuminance of the illuminated area can be precisely controlled,
Power saving is fully achieved. Moreover, the use environment and situation such as changes in external light are urgent! ! Since the illuminance can be adjusted automatically in response to changes in t'J, humans are freed from the task of controlling illuminance based on their senses.
