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) Controlling the illuminance of lighting is necessary to ensure appropriate illuminance for the illuminated area, to achieve the necessary and sufficient amount of electricity for lighting, that is, to save power, and to control the lighting by blinking and adjusting it. It is becoming popular for the purpose of saving labor by automatically operating lights, etc.

Conventional lighting systems that control illuminance include a centralized control method used in large-scale lighting systems for offices, stores, etc.
The lighting fixtures of each group are connected to the central control device by electrical wiring, and the lighting fixtures of each group are connected to each other by electrical wiring. Taking into account time schedules, 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 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. Also, the installation location of the optical sensor, which is usually installed in a place where the illumination of sunlight can be detected such as near a window, and the installation location of the lighting equipment do not necessarily correspond to each other, so it is difficult to adjust the illuminance of the illuminated area depending on the practical arrangement. It is not possible to manage the animals in a truly appropriate way, and because they are managed collectively for each group,
Individual lighting fixtures within a group cannot be managed. Furthermore, since detailed management is not possible for each location of use, and the illuminance of the illuminated area cannot be truly controlled, it is not possible to achieve the necessary and sufficient amount of electricity costs for lighting, that is, to save power. Furthermore, the optical sensor detects noise from the outside (for example, the sun's obscuring clouds, blinds and curtains swinging due to the wind, etc.).
If the device is covered, the detected illuminance value may suddenly change or become distorted. As a result, sudden changes or fluctuations occur in the dimming state of the light source in the lighting equipment, making it difficult to consistently obtain an appropriate illuminance and causing discomfort.

On the other hand, in small-scale lighting systems such as those for residential use, the necessary illuminance is judged 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 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. In addition, by controlling the illuminance at the illuminated area, it is possible to obtain the optimum illuminance and save power.Furthermore, it is possible to suppress the influence of changes in illuminance due to noise light, and moreover, it is possible to The object of the present invention is to provide a lighting system that can free the FL business from managing illuminance intuitively.

It includes a signal transmitter 25 that transmits signals via a wireless medium, and a power source 26 that is connected to a commercial power source via a storage battery, a solar battery, or an AC adapter. 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.

The illuminance detection section 21 also includes a series circuit of a photodiode 27 and a capacitor 28, which detect the illuminance by receiving light from the light source 13 or external light (sunlight, light from nearby lighting, etc.). Be prepared.

Further, the noise light control circuit 22 includes a filter circuit 29
and a time constant circuit 30. This filter circuit 2

Further, the time constant circuit 30 sets a constant time constant using a resistor 32, a capacitor 33, etc.
Illuminance detection signals that cannot be eliminated, for example, signals of illuminance detection values that instantaneously change with a large width, are not transmitted to the illuminance comparison and judgment section 23, and the illuminance detection signals are used for illuminance comparison and judgment using slow changing speeds. I will inform the department 23.

FIG. 2 also shows the illuminance setting section 24 of the remote control section 12.
For example, reference numeral 41 indicates a setting designation section, which includes a setting button 42 for designating the start of illuminance setting and a setting end button 43 for designating the end of illuminance setting. Also, 44

Although not shown, the illuminance setting unit 24 has a slide switch and a rotary switch for adjusting the illuminance target value, and also has two lamps for brightness increase and dimming, for example, to adjust the illuminance toward the target dimming value. It has a monitor that displays that the brightness is being adjusted to increase or decrease the brightness.

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, each lighting equipment section 11 (
These different address numbers 1 to 4 are set in the address setting section 17.
When there are multiple lighting equipment sections 11 and the dimming of some of them is performed at once, that is, when controlling the plurality of lighting equipment sections 11 as one group, is the lighting fixture part 1 of those groups.
1 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 in FIG. 3. In addition, as mentioned above, there are four or more lighting equipment units 11, and the addresses No. 1 to /
It is assumed that I is set respectively.

Press the setting button 42 of the illuminance setting section 24 of the remote control section 12,
The mode specifying section 44 selects and specifies the mode number, and the address specifying section 46 selects and specifies the address N of the lighting equipment section 11.
O is selected and specified, and the dimming state is specified in the dimming specifying section 48. For example, in the specified state of mode No. 1,
After specifying address No. 1, specify the on button 49 to set the lighting fixture section 11 of address No. 1 to turn on, then after specifying address No. 2, specify the on button 50. This sets the lighting fixture section 11 at address No. 2 to OFF, and continues (J, address N.

After setting 3, the lighting fixture section 11 at address No. 3 is set to automatic dimming by specifying the automatic dimming button 51.
Next, after setting the address No. 4, the lighting device section 11 of the address No. 4 is set to 50% dimming by specifying the 50% dimming button 52.

In addition, the on button 49, the on button 50, and the 50% dimming button 52
After specifying , or by directly operating the brightness increasing 54 or dimming 55, it is possible to set an arbitrary dimming value such as 30% or 80%, for example. Then, when setting is completed for mode No. 1 and you want to continue setting for other modes, after specifying the other mode, specify the address and perform the dimming installation 6 setting in the same procedure, and, When all settings are completed, the setting end button 43 is designated to complete the setting. These dimming settings are determined by the illuminance setting section 2 of the remote control section 12 for each mode.
It is stored in the memory of 4.

Next, the operation of controlling the illuminance m+ by the illumination system in which the dimming setting has been performed as described above will be explained.

For example, when mode Na 1 is specified on the remote controller 12,
Each address No. 1 to 4 dimming setting contents stored in the memory of mode No. 1 are determined by the illuminance comparison and determination section 23.
The signal is transmitted as a dimming command signal from the signal transmitter 25 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 dimming command signal includes each address No.
1 to 4 are marked "A" respectively.

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 signals received by the signal receiving section 18 are transmitted to the CPU 16, but even if a dimming command signal with an address number other than the address specified by the address setting section 17 is input, it will not accept it. Only when the address N0 set in the address setting section 17 is input, the dimming command signal is accepted and input. Then, the c p U 16 controls the dimming unit 14 in accordance with the dimming command signal to dim the light source 13 .

For example, the lighting equipment section 1 to which an on dimming command signal is input.
1, the light source 13 is turned on, and the light source 13 is turned off in the lighting equipment section 11 to which the off dimming command signal is input, and the light source 13 is turned on, and the light source 13 is turned off at 50%.
In the lighting equipment section 11 to which the dimming command signal for dimming is input, the light source 13 is turned on at 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. 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 23. This illuminance comparison/judgment section 23 compares the detected illuminance value with the illuminance setting section 2.
4, and if it is determined that illuminance correction is necessary, increase the brightness of the automatic dimming (including turning on from continuous lighting) or dimming (including turning off the lights). Outputs a dimming command signal. For example, when the illuminance due to outside light is high in the daytime, the illuminance detection value of the illuminance detection unit 21 will be higher than the illuminance target value, so the light source 13 Outputs a dimming command signal,
Furthermore, when the illuminance due to external light decreases in the evening, the illuminance detection value becomes lower than the illuminance target value, so a dimming command signal for increasing the brightness of the 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 23 is transmitted from the signal transmitting section 25 via a wireless medium.

In the lighting equipment section 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 performs dimming based on the dimming command signal. The light unit 14 is controlled to dim or increase the light source 13.

In this way, the remote control unit 12 detects the illuminance, and transmits a dimming command signal for automatically dimming or increasing the brightness until the detected illuminance value reaches the illuminance target value, and the illuminance set for automatic dimming is In the fixture section 11, the light source 13 is dimmed based on the dimming command signal. Therefore, for example, by setting the lighting fixtures 11 on either side of the desk where you work to automatic dimming and placing the remote controller 12 on the desk, you can always obtain appropriate illuminance at your hand.

The illuminance detection unit 21 of the remote control unit 12 also detects, for example, when the sun is obscured by clouds, when blinds or curtains are swayed by wind,
Noisy light may be received due to the effects of vehicle lights, light blocking or reflection from pedestrian traffic, fluctuations in the power supply shared with other electrical equipment, etc. In this case, as shown in FIG.
The capacitor 31 of the time constant circuit 30 or the resistor 32 of the time constant circuit 30 and the capacitor 33 are used to eliminate the illuminance detection signal S2, which is not transmitted to the illuminance comparison/judgment section 23 and changes rapidly. The rising portion is eliminated based on a constant time constant set by the capacitor 33, and a signal of the detected illuminance value that has been changed moderately is transmitted to the illuminance comparison and determination section 23. Therefore, the light source 1 of the lighting equipment section 11
No fluctuations or sudden changes occur in the dimming state of No. 3, and a constant and appropriate illuminance can be obtained. Note that the slowly changing illuminance detection signal S3 from the illuminance detection section 21 is transmitted to the illuminance comparison and determination section 23 at a rate of change of - between roads.

Also, depending on the situation, the mode specifying section 44 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 of the -[- modes set in advance, such as selecting mode N0 in which the light is 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 press the Specify the light state. For example, the lighting fixture section 1 of address No. 1 is in the lighting state.
1, specify the address Nα1 on the remote controller 12 and then operate the dimming button 55 to adjust the dimming command signal for manual dimming to the address Nα1.
o, 1 is transmitted from the remote control unit 12 together with the dimming command signal, and the lighting fixture unit 11 at the corresponding address Na 1 accepts the dimming command signal, controls the dimming units 1 to 14, and dims the light source 13. . This manual adjustment can be set to on, off, brightness increase, dimming, 50% dimming, and automatic dimming.
Furthermore, even if automatic dimming is set, manual dimming is given priority. In this case, from the user's location,
You can adjust the brightness while checking it.

Furthermore, by adjusting the illuminance target value with the illuminance setting section 24 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. .

Furthermore, by operating the all-lights-off button 53 of the screen controller section 12, all the lighting equipment sections 11 are turned off.

In addition, the mode can be set to m using the mode specifying section 44 of the remote control section 12.
If the number of lights is sufficient, manual dimming or total extinguishment is canceled and dimming control corresponding to the designated mode is performed.

In addition, when controlling several lighting equipment units 11 as one group, the same address No. is set for each group.
- However, if you want to change the composition of the group, each illuminator
The address setting section 17 of the section 11 allows the setting of the address number to be easily changed by simply changing the setting.

In addition, if you want to change the illuminated area to obtain the optimum illuminance by changing your seat, etc., the illuminance detection section 21 is provided.
By changing the 11th part 12 and moving it to the location of the lJ illuminated part, the optimum illuminance of the changed illuminated part becomes 1!7.
It will be done. 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.

By connecting the lighting fixture section 11 and the remote control section 12 using a wireless medium, as shown in "-", there is no need for special wiring work, and the address N of the lighting fixture 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 desired location. can be done inexpensively. Furthermore, since the installation location of the remote control unit 12 having the illuminance detection unit 21 corresponds to the installation location of the lighting equipment unit 11, it is possible to perform management that truly corresponds to the illuminance of the illuminated area, which is actually important. , 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,
The necessary and sufficient lighting electricity bill, that is, 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.

Furthermore, even if the remote control section 12 receives noise-like light, the filter circuit section of the chord-like light control circuit 22 suppresses the influence of the noise-like light on the illuminance detection signal transmitted from the illuminance detection section 21 to the illuminance comparison and determination section 23. 29 and the time constant circuit 30, there is no fluctuation or sudden change in the dimming state of the light source 13 of the lighting fixture section 11, and a constant and appropriate illuminance can be obtained.

In the above embodiment, the filter circuit section 29 and the time constant circuit section 30 are combined into two branches as the noise light control circuit 22, but they may be provided separately.

Further, the noise-like light control circuit 22 may include a configuration in which the illuminance comparison and determination section 23 and the signal transmission section 25 of the remote control section 12 are configured to eliminate signals affected by noise-like light. , may be provided in the lighting fixture section 11.

In addition, when performing group control on a plurality of lighting equipment sections 11, if it is assumed that the groups will not be changed, it is possible to perform group control on a plurality of lighting equipment sections 11 in which only the light source 13 and the dimming unit 14 are shifted to the right. One receiving control unit 1 for
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, and each remote control unit 12 may control a plurality of lighting equipment units 11 for each predetermined location.
