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.

(Prior art) Controlling the illuminance of lighting is necessary to ensure appropriate illuminance for the illuminated area, to reduce electricity costs for lighting as much as necessary, and to reduce power consumption. It is becoming popular for the purpose of saving labor by automatically performing operations such as blinking and dimming.

Conventional lighting systems that control illuminance include a centralized control method used in large-scale lighting systems for offices, stores, etc.
Create multiple groups, connect each group's lighting fixtures and the central control device with electrical wiring, and set a time schedule such as where each group's lighting fixtures will be used, what they are used for, and the time and day of the week. In consideration of the above, dimming control is performed centrally for each group through each electrical wiring using a central control device. In addition, in such a centralized control method, for example, a light sensor is installed near a window and connected to a central control device with electrical wiring, and the light sensor detects sunlight or other external light near the window and uses it as a control factor. There is also a system.

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.

(Problem to be Solved by the Invention) However, in the above-mentioned centralized control type lighting system, special wiring work is required to connect the central control device and each group of lighting equipment and optical sensors with electrical wiring. The system configuration, such as the breakdown of lighting equipment groups, the layout of each group, and the installation location of optical sensors, cannot be easily changed, and the system configuration is large-scale and requires wiring work. Due to the requirements, the system is expensive.

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 management is not possible for each location of use, and since it is not possible to truly manage the illuminance of the illuminated area, it is not possible to achieve the necessary and sufficient amount of electricity costs for lighting, that is, to save power.

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 management. It is troublesome to manually adjust the brightness every time the illuminance changes.

In addition, with lighting systems that perform automatic dimming as described above, it is not possible to confirm whether or not the dimming is actually being automatically adjusted to the target illuminance, and even with manual dimming, the dimming signal is not sent from the remote controller. You cannot confirm whether the lighting fixture is receiving the dimming signal until the dimming of the lighting fixture's light source changes.

The present invention was created in view of the above-mentioned problems, and by using a wireless medium for dimming commands and eliminating the need for wiring work, the system can be easily changed and the system configuration can be made small and inexpensive. Furthermore, by controlling the illuminance at the illuminated area, it is possible to obtain the optimum illuminance and save power, freeing people from the task of managing illuminance intuitively, and in addition, it is possible to achieve a state in which the illuminance changes to the target illuminance. An object of the present invention is to provide a lighting system capable of confirming the transmission or reception status and the state in which the illuminance changes to the target illuminance on the transmitting side or the receiving side of the wireless medium or both. The purpose is to provide a lighting system that can

Note that the wireless medium transmitted from the signal transmitter 24 includes infrared rays and radio waves, and a light emitting diode is shown in the drawing.

Further, the illuminance setting section 23 of the remote control section 12 has a setting means 26 for setting a target illuminance, and this setting means 26 is composed of, for example, a slide volume or a rotary volume, and the illuminance is set around the lever or knob of the volume. Set up a scale that displays the level.

Furthermore, the remote control unit 12 has a display unit 27 that displays the state in which the illuminance changes to the target illuminance.
For example, as shown in FIG. However, when it is determined that the target illuminance A and the detected illuminance B match (when the dimming command signal is not output from the illuminance comparison and determination section 22), the (-) lamp 1-1 is turned on. Displays a state that matches the target illuminance △, and on the other hand, when the detected illuminance B is determined to be lower or higher than the target illuminance A.

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. In the case of controlling separately, different addresses NQ 1 to 4 are set for each lighting fixture section 11 by the address setting section 17, and if there are a plurality of lighting fixture sections 11, some of the lighting fixture sections 11 When performing the dimming all at once, that is, when controlling a plurality of lighting fixtures 11 as one group, the lighting fixtures 11 of those groups are set to the same address number.

Next, the procedure for setting the dimming of each lighting device section 11 will be explained with reference to the flowchart of FIG. 4. In addition, as mentioned above, there are four or more lighting equipment units 11, and address numbers 1 to 4 are provided.
It is assumed that each of these is set.

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 Nα1 is set to turn on by specifying the on button 39,
Next, after specifying address No. 2, press the on button 40.
By specifying , the lighting fixture section 11 at address Na 2 is set to off, and then after setting address N03,
By specifying the automatic dimming button 41, the lighting fixture section 11 at address No. 3 is set to automatic dimming, and then, after setting address No. 4, by specifying the 50% dimming button 42. The lighting fixture section 11 at address No. 4 is set to 50% dimming. In addition, on button 39
, after specifying the on button 4o and the 50% dimming button 42, or by directly operating the brightness increasing side 44 or dimming button 45, it is possible to set the dimming value to an arbitrary dimming value such as 30% or 80%. Then, when setting is completed for mode Nα1 and you want to continue setting for other modes,
After specifying another mode, address is specified and dimming setting is performed in the same manner, and when all settings are completed, the setting end button 33 is specified to complete the setting. These dimming settings are stored in the memory 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 illumination 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 N stored in the memory of mode No.
Each of the dimming setting contents of a 1 to 4 is transmitted as a dimming command signal through the illumination comparison and determination section 22 from the signal transmitting section 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 Na 1 to 4, and each dimming command signal has addresses No. 1 to 1.
-4 are given respectively. At this point, the display section 27
Then, it may be displayed that the dimming command signal is being transmitted.

In each lighting equipment section 11, the signal receiving section 18 receives a dimming command signal transmitted from the remote control section 12 via a wireless medium, and
Send to P U 16. All the signals received by the signal receiving section 18 are transmitted to this CPU 16, but even if a dimming command signal with an address NO other than the address Nα 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 lighting equipment section 11 to which an on dimming command signal is input.
Then, the light source 13 is turned on, and the light source 13 is turned on in the lighting fixture section 11 to which the off dimming command signal is input. 'j! 1 and into which a dimming command signal of 50% dimming is input.
In step 1, the light source 13 is turned on with 50% dimming. In addition, C.P.
When the U16 receives the dimming command signal at the predetermined address Nα, the display unit 20 displays the reception state and the state in which the illuminance is being changed to the target illuminance.

In addition, if there is an address No. set to automatic dimming, the lighting fixture section 11 of that address No. is set to the remote control section 1.
Automatic dimming control is performed to the target illuminance set by the setting means 26 of the illuminance setting section 23 of No. 2. The control operation of this automatic light adjustment is shown in the flowchart of 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 dimming is increased (including turning on from the off state) or dimming (including turning off the light). ) outputs a dimming 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. In addition, when the illuminance due to outside light decreases in the evening, the detected illuminance value will be lower than the target illuminance value, so in order to increase the illuminance from the light source 13, a dimming command signal for increasing the brightness of automatic dimming is output. Output. When the illuminance comparison and determination section 22 determines that the illuminance is to be reduced or increased, the display section 27 displays that the illuminance is to be reduced or increased to the target illuminance.

Furthermore, if the illuminance comparison and determination section 22 determines that the illuminance is appropriate,
Although the dimming command signal is not output, a dimming command signal instructing to maintain the status quo may be output. At this point, the display unit 20 displays that the current illuminance matches the target illuminance.

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 section 11 set to automatic dimming, when the address numbers match and a dimming command signal for dimming or increasing the brightness of automatic dimming is received, the lighting equipment section 11 sets c p U based on the dimming command signal. 16 controls the dimming unit 14 to dim or increase the brightness of the light source 13. Further, at this time, the display unit 20 displays the reception state and the state in which the illuminance is being changed to the target illuminance.

In this way, the remote control unit 12 detects the illuminance, and transmits a dimming command signal for automatic dimming or increasing the brightness until the detected illuminance value reaches the target illuminance value, and the illuminance set for automatic dimming is In the fixture section 11, the light is adjusted based on the dimming command signal.
Perform 13 dimming. 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. Further, it is possible to confirm that the light is in the automatic dimming state using the display section 27 of the remote control section 12 and the display section 20 of the lighting fixture section 11.

Also, depending on the situation, the mode specifying section 34 of the remote control section 12
Select the mode from. 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 work, the atmosphere created, the worker's mood, physical condition, age, eye condition, preference, etc. Therefore, if you want to manually adjust the dimming of a certain lighting fixture section 11 individually, first specify the address number of the lighting fixture section 11 you want to adjust using the remote control section 12, and then specify the dimming state using the dimming specification section 38. Specify. For example, the lighting fixture section 11 of address No. 1 that is in a lit state
If you want to adjust the dimming of the manual dimming, specify the address Na 1 on the remote controller 12 and then operate the dimming box 45 to adjust the dimming command signal for manual dimming to the address N.
The light control unit 11 at the corresponding address Nα1 receives the dimming command signal and controls the dimming unit 14 to dim the light source 13. Also, at this time, the display section 2 of the upper controller section 12
7 displays the state in which the illuminance is changing to the target illuminance set manually, and the display unit 20 of the specified lighting fixture unit 11 displays the reception state and the state in which the illuminance is changing to the target illuminance. You can check the transmission status and reception status, and in particular, even if you do not know the address number of the lighting equipment section 11, you can increase the illuminance of other lighting equipment sections 11 by searching for the corresponding address Nα while watching the lighting of the display section 20. You don't have to go crazy.

Note that this manual adjustment can be set to turn on, turn off, brighten, dim, 50% brightness, and automatic brightness, and even if automatic brightness is set, manual operation is performed with priority. 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 this case, the display section 27 of the remote control section 12 and the display section 20 of the lighting fixture section 11 display a state in which the illuminance changes to the target illuminance.

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

If the mode is designated again using the mode designation section 34 of the remote control section 12, manual dimming or total light-off is canceled and dimming control corresponding to the designated mode is performed.

Furthermore, when performing group control on several lighting equipment sections 11 as one group, the same address Nα is set for each group, but when it is desired to change the configuration of the group, the address setting section of each lighting equipment section 11 17 to change the setting of address N0. This can be easily done with ().

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 operation as described above.

As described above, by connecting the lighting equipment section 11 and the remote control section 12 using a wireless medium, there is no need for special wiring work, and simply by switching the address Nα of the lighting equipment section 11, the dimming control group can be controlled. Since changes can be easily made and the remote control unit 12 having the illuminance detection unit 21 can be moved to any location, the system configuration can be small-scale and the system can be made inexpensive. 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 precisely controlled, it is possible to achieve the necessary and sufficient amount of electricity for lighting, that is, to save power. 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 display section 27 of the remote control section 12 and the lighting equipment section 1
Since the display unit 20 of 1 can display the state in which the illuminance changes to the target illuminance, it is confirmed that the light of the lighting equipment unit 11 [13] is dimmed so that the current illuminance matches the target illuminance. At the same time, the transmission status from the remote control unit 12 and the reception status at the lighting equipment unit 11 can be confirmed.

The display section 27 of the remote control section 12 may turn on a green lamp when the target illuminance is met, and turn on a red lamp when the illuminance does not match. The state in which no illuminance is performed may be a state in which the target illuminance is matched, and furthermore, when a liquid crystal display is used as a display means, the target illuminance and the detected illuminance may be displayed numerically or graphically.

Further, in the above embodiment, the remote control unit 12 and the lighting equipment unit 11
Although the display sections 27 and 20 are provided on both sides, it is also possible to install them on only one of them, or to connect the remote control section 12 and the lighting equipment section 11 with separate adapters. good.

Note that when performing group control on a plurality of lighting equipment sections 11, if it is assumed that the group will not be changed, the following applies to the plurality of lighting equipment sections 11 having only the light source 13 and the dimming unit 14. 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.
