(Embodiment 1)
<Configuration and functions>
A lighting system 1 according to the following embodiment will be explained using FIGS. 1 to 5.

FIG. 1 is a block diagram showing a lighting system 1 according to the first embodiment. FIG. 2 is a schematic diagram showing a case where each of the plurality of illumination devices 10 irradiates light onto an irradiated surface. FIG. 3 is a diagram showing luminous intensity, control signals, and horizontal illuminance. FIG. 4A is a diagram showing a case where the light irradiated onto the irradiated surface changes linearly when each of the plurality of illumination devices 10 irradiates the irradiated surface with light. FIG. 5 is a diagram showing a case where the light irradiated onto the irradiated surface changes in a planar manner when each of the plurality of illumination devices 10 irradiates the irradiated surface with light.

As shown in FIG. 1, the lighting system 1 is an affordance lighting system that can guide people by adjusting the illumination mode of light emitted from the lighting device 10. For example, the lighting system 1 of the present embodiment can guide people in a predetermined direction, gather guided people in a predetermined area, or disperse people gathered in a predetermined area by adjusting the lighting mode. You can be induced to do so. For example, the savannah effect is known, in which people are guided to areas with bright vertical illuminance rather than areas with dark vertical illuminance. For this reason, since lighting system 1 illuminates the ground, it is strictly different from the savannah effect that is related to vertical illuminance, but it aims to achieve an effect similar to the savannah effect by transitioning the brightness and darkness of the light. This effect can be used to guide people by influencing their emotions.

Such a lighting system 1 is used in places where it is necessary to guide many people, such as parks, amusement parks, stations, large-scale facilities, and the like.

As shown in FIGS. 1 and 2, the lighting system 1 includes a plurality of lighting devices 10, a lighting control device 2, and a power supply section 30.

[Lighting device 10]
Each of the plurality of lighting devices 10 is, for example, an outdoor lighting device 10 such as a street light, a facility lighting device 10 installed within a facility, or the like. Each of the plurality of lighting devices 10 of this embodiment is arranged along a passage. In FIG. 2, five lighting devices 10 are illustrated as the plurality of lighting devices 10. Note that the number of lighting devices 10 is just an example, and is not limited to five lighting devices 10. For example, the number of lighting devices 10 may be two or more, preferably three or more. Further, the lighting device 10 is an example of a first light source section and a second light source section.

Each of the plurality of lighting devices 10 includes a light source 11, a light emission control circuit (not shown), and the like. The light source 11 is a light emitting module in which a plurality of LED (Light Emitting Diode) elements are mounted. Each of the plurality of LED elements includes a red LED chip, a blue LED chip, a green LED chip, a white LED chip, and a yellow LED chip. Further, the light source 11 may be configured to emit white light by combining a blue LED and a yellow phosphor. Furthermore, the light source 11 may emit various light colors by selectively combining two or more of these LED elements. Note that the present invention is not limited to these, and a commonly used configuration may be used. The light emission control circuit independently controls each LED chip, so that each of the plurality of lighting devices 10 emits light to the irradiated surface and irradiates the irradiated surface with light. Further, the light source 11 may be an example of a first light source section and a second light source section.

When the lighting device 10 receives a control signal from the lighting control device 2, it lights up in a lighting mode according to the control signal. The lighting device 10 has a dimming function and a color adjusting function.

For example, as a dimming function, the lighting device 10 can darken or brighten the brightness of the light emitted by adjusting the brightness of the light emitted by the light source 11 to a plurality of levels. In other words, the lighting device 10 can periodically vary the brightness and darkness of the emitted light. Here, periodic may be the same period or different periods.

Moreover, the lighting device 10 can emit white light with a color temperature ranging from a low color temperature such as a light bulb color to a high color temperature such as warm white, neutral white, or daylight color as a color adjusting function. In other words, the lighting device 10 can periodically fluctuate the hue of the emitted light. For example, in lighting effects, the lighting device 10 periodically changes the color temperature so as to repeat increasing and decreasing the redness of the emitted light.

Note that the lighting device 10 may change the color of the emitted light by changing the wavelength of the emitted light as a lighting effect.

The first lighting device 10, the second lighting device 10, the third lighting device 10, the fourth lighting device 10, and the fifth lighting device from the other side of the plurality of lighting devices 10 in FIG. The relationship between the lighting device 10 and the first light irradiation area, the second light irradiation area, the third light irradiation area, the fourth light irradiation area, and the fifth light irradiation area will be described.

The first lighting device 10 irradiates the emitted light onto a first light irradiation area on the irradiation target surface of the passage. The second lighting device 10 irradiates the emitted light onto a second light irradiation area on the irradiation target surface. The third illumination device 10 irradiates the third light irradiation area on the irradiation target surface with the emitted light. The fourth lighting device 10 irradiates the emitted light onto a fourth light irradiation area on the irradiation target surface. The fifth illumination device 10 irradiates the fifth light irradiation area on the irradiation target surface with the emitted light.

The first irradiated surface, the second irradiated surface, the third irradiated surface, the fourth irradiated surface, and the fifth irradiated surface are different locations on the irradiated surface of the passage. In FIG. 2, a first lighting device 10, a second lighting device 10, a third lighting device 10, a fourth lighting device 10, and a fifth lighting device 10 are arranged in this order. Therefore, the first light irradiation area, the second light irradiation area, the third light irradiation area, the fourth light irradiation area, and the fifth light irradiation area are also formed in line in this order. In the first light irradiation area, the second light irradiation area, the third light irradiation area, the fourth light irradiation area, and the fifth light irradiation area, two adjacent light irradiation areas may partially overlap.

[Lighting control device 2]
The lighting control device 2 can control the plurality of lighting devices 10 individually or collectively. In other words, the lighting control device 2 outputs a control signal for lighting each of the plurality of lighting devices 10 with a predetermined effect to each of the plurality of lighting devices 10, thereby controlling the plurality of lighting devices according to the control signal. 10 can be illuminated with a predetermined effect. That is, the lighting control device 2 controls each of the plurality of lighting devices 10 to illuminate with a predetermined effect indicated by the control signal.

The lighting control device 2 includes a control section 20.

The control unit 20 transmits a control signal capable of controlling each of the plurality of illumination devices 10 that emit light so that the light is irradiated to two or more places in the passage (two or more illuminated surfaces). Output to each of the devices 10. The control signal indicates whether the luminous intensity of the light emitted by each of the first lighting device 10a and the second lighting device 10b or the illuminance of the light emitted by each of the first lighting device 10a and the second lighting device 10b increases or decreases over time. It is a dynamic signal that repeats. For this reason, each of the plurality of lighting devices 10 emits light such that the luminous intensity or illuminance dynamically repeatedly increases and decreases depending on the control signal.

As shown in FIG. 3, the control signal per cycle may be a dynamic output signal consisting of a waveform signal that increases only once and a waveform signal that decreases only once. . Further, the control signal per cycle may be a dynamic output signal consisting of a signal with a waveform that increases twice or more and a signal with a waveform that decreases twice or more. Therefore, the illuminance of the light emitted by each of the first lighting device 10a and the second lighting device 10b per cycle is dynamic, consisting of light whose illuminance increases only once and light whose illuminance decreases only once. It is a light. Furthermore, the illuminance of the light per cycle emitted by each of the first lighting device 10a and the second lighting device 10b is dynamic, consisting of light whose illuminance increases twice or more and light whose illuminance decreases twice or more. It may be light. Note that the control signal may also include one for turning off or turning on the output of the lighting device 10.

Note that the control signal shown in FIG. 3 is just an example, and the control signal is not limited to that shown in FIG. 3.

In addition, since the first lighting device 10a and the second lighting device 10b included in the plurality of lighting devices 10 are arranged side by side in this order from the other side to the one side of the passage, the first lighting device 10a Different control signals are output to the second lighting device 10b. Specifically, the control unit 20 selects between the first lighting device 10a and the control signal that has a difference of 3% or more when comparing at least one of the following four comparisons (1) to (4). It outputs to each of the second lighting devices 10b. (1) is a comparison between the maximum value Pa of the luminous intensity of the light emitted by the first lighting device 10a and the maximum value Pb of the luminous intensity of the light emitted by the second lighting device 10b. (2) is the average value of the maximum value Ra immediately after the minimum value Qa in the luminous intensity of the light emitted by the first lighting device 10a and the minimum value Qa, and the luminous intensity of the light emitted by the second lighting device 10b. This is a comparison between the maximum value Rb immediately after the minimum value Qb over time and the average value of the minimum value Qb. (3) is the maximum value of the horizontal illuminance of the illuminated surface irradiated with the light emitted by the first illuminating device 10a, and the maximum value of the horizontal illuminance of the illuminated surface irradiated with the light emitted by the second illuminating device 10b. This is a comparison. (4) is the average value of the horizontal illuminance of the illuminated surface irradiated with the light emitted by the first illuminating device 10a, and the average value of the horizontal illuminance of the illuminated surface irradiated with the light emitted by the second illuminating device 10b. This is a comparison.

This 3% is a value set so that people can recognize differences in brightness. Therefore, humans can recognize a difference in brightness if the difference is 3% or more.

Here, the difference of 3% or more may be, for example, a case where there is a difference of 3% between the maximum value Pb of the second lighting device 10b and the maximum value Pa of the first lighting device 10a. The maximum value Pa of the first lighting device 10a may differ by 3% from the maximum value Pb of the device 10b. Either one may be selectively set as a reference.

Note that the horizontal illuminance of the irradiated surface is measured with different illuminance values depending on the orientation of the illuminance meter. Specifically, even if the illuminance meter is placed in the same location, the light incident on the irradiated surface will be measured differently depending on whether it is oriented toward the light source or when it is placed horizontally. Therefore, in this embodiment, the horizontal illuminance of the irradiated surface is defined as the illuminance when the illuminance meter is placed horizontally, that is, when the light receiving surface faces vertically upward.

Further, in a case where the first lighting device 10a and the second lighting device 10b included in the plurality of lighting devices 10 are arranged in this order from the other side to the one side of the passage, the control unit 20 The first lighting device 10a and the second lighting device are arranged such that the first lighting device 10a is higher than the second lighting device 10b when at least one of the four comparisons (1) to (4) is made. A control signal for controlling each of the devices 10b is output. That is, as shown in FIG. 2, the control unit 20 generates and outputs a control signal that increases the output of the light emitted by the first lighting device 10a disposed on the other side, The first lighting device 10a located closer to the person can have higher luminous intensity or the horizontal illuminance of the irradiated surface than the second lighting device 10b located closer to the person.

In this case, for example, the maximum value of the output value in the control signal output to the first lighting device 10a is set to P1. Further, the maximum value of the output value in the control signal output to the second illumination device 10b, which is after the maximum value P1 over time, is assumed to be P2. Further, in the control signal output to the first lighting device 10a, the maximum value immediately after the maximum value P1 over time is set as P3. Further, the maximum value of the horizontal illuminance of the irradiated surface irradiated with the light emitted by the first illumination device 10a is set as S1 so as to correspond to the maximum value. Further, the maximum value of the horizontal illuminance of the irradiated surface irradiated with the light emitted by the second lighting device 10b is set as S2 so as to correspond to the maximum value P2. Further, the maximum value of the horizontal illuminance of the irradiated surface irradiated with the light emitted by the first lighting device 10a is set as S3 so as to correspond to the maximum value. Further, the time difference between the time of the maximum value P1 and the time of the maximum value P2 is assumed to be t1. Further, the time difference between the time of the maximum value P2 and the time of the maximum value P3 is assumed to be t2. Further, the time difference between the time of the maximum value S1 and the time of the maximum value S2 is assumed to be t3. Further, the time difference between the time of the maximum value S2 and the time of the maximum value S3 is assumed to be t4. At this time, when t2>t1 or t4>t3, at least one of the four comparisons is larger in the first lighting device 10a than in the second lighting device 10b. In this way, since the output value of the control signal of the first illuminating device 10a is larger than that of the second illuminating device 10b, the light irradiation area of the illuminated surface irradiated with the light emitted by the first illuminating device 10a is However, the area is brighter than the light irradiation area of the irradiated surface that is irradiated with the light emitted by the second illumination device 10b.

Further, in each of the first lighting device 10a and the second lighting device 10b, there is a difference of 27% or more between the maximum value and the minimum value of the luminous intensity, and the maximum value and the minimum value of the horizontal surface illuminance irradiated to the irradiated surface. There is a difference of more than 27%. Specifically, there is a difference of 27% or more between the maximum value Pa and the minimum value Qa of the luminous intensity of the light emitted by the first lighting device 10a. Further, there is a difference of 27% or more between the maximum value Pb and the minimum value Qb of the luminous intensity of the light emitted by the second lighting device 10b. Further, there is a difference of 27% or more between the maximum value and the minimum value of the horizontal plane illuminance of the irradiated surface irradiated with the light emitted by the first illumination device 10a. Further, there is a difference of 27% or more between the maximum value and the minimum value of the horizontal plane illuminance of the irradiated surface irradiated with the light emitted by the second illumination device 10b. For example, in each illumination device 10 that irradiates light irradiation areas A1 to A7 in FIG. 4A, there is a difference of 27% or more between the maximum and minimum luminous intensity, and A control signal for controlling each of the first lighting device 10a and the second lighting device 10b is output so that the maximum value and the minimum value of the horizontal illuminance have a difference of 27% or more.

Here, the difference of 27% or more may be a case where there is a difference of 27% between the minimum value of the control signal and the maximum value of the control signal. The maximum value may differ by 27%. Either one may be selectively set as a reference. The same applies to other values.

Further, in each of the first lighting device 10a and the second lighting device 10b, there is a difference of 31% or more between the maximum value and the minimum value of the luminous intensity, and the maximum value and the minimum value of the horizontal surface illuminance irradiated onto the irradiated surface. There may be a difference of 31% or more. Furthermore, in each of the first lighting device 10a and the second lighting device 10b, there is a difference of 47% or more between the maximum value and the minimum value of the luminous intensity, and the maximum value and the minimum value of the horizontal surface illuminance irradiated to the irradiated surface. There may be a difference of 47% or more.

Further, the phases of the respective control signals output to the first lighting device 10a and the second lighting device 10b among the plurality of lighting devices 10 are different. Specifically, the control unit 20 transmits control signals having different phases to each of the first lighting device 10a and the second lighting device 10b. That is, the control unit 20 transmits control signals having different phases as shown by the solid line and the broken line in FIG. 3 to each of the first lighting device 10a and the second lighting device 10b. As a result, as shown in FIG. 3, the output waveform of the light emitted by the first lighting device 10a and the output waveform of the light emitted by the second lighting device 10b are different in phase.

Moreover, the cycles of the respective control signals output to the first lighting device 10a and the second lighting device 10b may be the same. In other words, the control signal may be outputted to each of the first lighting device 10a and the second lighting device 10b with different phases.

Furthermore, the periods of the respective control signals output to the first lighting device 10a and the second lighting device 10b may be different. That is, the control signal may be output to each of the first lighting device 10a and the second lighting device 10b at different cycles.

Further, when the light emitted from each of the first lighting device 10a and the second lighting device 10b is irradiated onto the irradiated surface, the light irradiated onto the irradiated surface may be linear, curved, sawtooth, or planar. The transition may be in a shape, an L shape, or a diagonal shape. In other words, in the lighting system 1, each of the first lighting device 10a and the second lighting device 10b emits light, so that the light irradiated onto the irradiated surface can be linear, curved, sawtooth, planar, or L-shaped. Create a continuous movement in a diagonal or diagonal pattern.

Here, the linear transition of the light irradiated onto the irradiated surface will be explained using FIG. 4A. FIG. 4A illustrates a case where seven lighting devices 10 are used as the plurality of lighting devices 10 in the lighting system 1.

The first lighting device 10 from one side illuminates the light irradiation area A1. Moreover, the second lighting device 10 from one side illuminates the light irradiation area A2. Moreover, the third lighting device 10 from one side illuminates the light irradiation area A3. Moreover, the fourth lighting device 10 from one side illuminates the light irradiation area A4. Further, the fifth lighting device 10 from one side illuminates the light irradiation area A5. Further, the sixth lighting device 10 from one side illuminates the light irradiation area A6. Moreover, the seventh lighting device 10 from one side illuminates the light irradiation area A7. As described above, the light irradiation areas A1 to A7 are arranged in this order from one side to the other side.

For example, in the first stage of FIG. 4A, the light irradiation areas A1 and A7 are the fifth brightest at the first illuminance, the light irradiation area A2 is the fourth brightest at the second illuminance, and the light irradiation area A3 is the third brightest at the third illuminance. , the light irradiation areas A4 and A6 have a fourth illuminance, which is the second brightest, and the light irradiation area A5 has a fifth illuminance, which is the first brightest.

Next, in the second stage, the light irradiation areas A1 and A4 are set to a third illuminance, which is the third brightest, the light irradiation area A2 is the fifth brightest, and the second illuminance is the fourth brightest. The irradiation areas A5 and A7 have a fourth illuminance, which is the second brightest, and the light irradiation area A6 has a fifth illuminance, which is the brightest.

Next, in the third stage, the light irradiation areas A1 and A7 are at the fifth brightness, the light irradiation areas A2 and A5 are the third brightest, and the light irradiation area A3 is the fifth brightest at the first illuminance. , the light irradiation area A4 has the fourth brightest second illuminance, and the light irradiation area A6 has the second brightest fourth illuminance.

In this way, for example, for a person on one side, the light at the brightest fifth illuminance illuminated on the irradiated surface makes the back of the passage appear brighter, and the light flows in a straight line from one side to the other. Looks like it's transitioning. Further, the speed at which the light changes linearly may be similar to the speed at which a person walks (a speed of about several kilometers per hour).

The same applies to the case where the light irradiated onto the irradiated surface changes in a curved shape, a sawtooth shape, an L-shape, or a diagonal shape. This embodiment can be applied to a passage having a curved shape, sawtooth shape, L-shape, or diagonal shape.

Further, the manner in which the light irradiated onto the irradiated surface changes in a planar manner will be explained using FIG. 4B.

For example, in FIG. 4B, the light irradiation areas A1 to A7 are arranged in this order from one side to the other. The same applies to the other light irradiation areas B1 to B7 and C1 to C7. Further, the first light irradiation areas A1, B1, and C1 are arranged in this order in the vertical direction. The same applies to the other light irradiation areas A2 to A7, B2 to B7, and C2 to C7.

The first lighting device 10 from one side illuminates the light irradiation areas A1, B1, and C1. The same applies to the second and subsequent lighting devices 10. In this case, each lighting device 10 includes a plurality of light sources 11.

For example, in FIG. 4B, light irradiation areas A1 to A7 are the third brightest, light irradiation areas B1 to B7 are the second brightest, and light irradiation areas C1 to C7 are the first brightest.

Even when the light irradiated on the irradiated surface transitions in a planar manner, the light irradiated on the irradiated surface transitions from one side to the other orthogonally (vertical direction) as shown in FIG. 4A. is omitted. Note that when the light irradiated onto the irradiated surface transitions in a planar manner, the light irradiated onto the irradiated surface may transition laterally.

Note that the transition is not limited to the example shown in FIG. 4B, and for example, the transition may be made radially from the illumination system 1 with the illumination system 1 at the center, or may be transitioned so as to converge toward the illumination system 1. Further, the light irradiated onto the irradiated surface is not limited to these examples, and may change freely.

In this way, for example, the light of the brightest fifth illuminance irradiated onto the illuminated surface transitions from the foot side of the illumination system 1 in a straight line, a curve, a sawtooth, a planar, an L-shape, or a diagonal line. Looks like it does. Further, the speed at which the light changes may be similar to the speed at which a person walks.

[Power supply section 30]
As shown in FIG. 1, the power supply section 30 has a function of supplying power to the plurality of lighting devices 10 and the lighting control device 2. The power supply unit 30 is, for example, a power supply circuit in which a plurality of electronic components are mounted on a printed circuit board. The power supply unit 30 generates, for example, driving power for causing each of the plurality of light sources 11 to emit light. Specifically, the power supply section 30 generates driving power for causing the light sources 11 to emit light, and supplies this driving power to each light source 11. In other words, the power supply unit 30 converts commercial AC power into DC power, supplies this DC power to each light source 11 as driving power to cause the light source 11 to emit light, and lights the light emitting element of the light source 11 in FIG. Make it emit light.

[Evaluation results]
First, the reason for the above-mentioned 3% or more will be explained using FIG. 5A. FIG. 5A is a diagram showing the relationship between the difference between the illumination intensity of the illumination device 10 of Embodiment 1 and the reference illuminance of the reference illumination device, and whether or not a subject can be identified.

First, two lighting devices 10 were arranged outdoors at 1 m intervals, and the two lighting devices 10 were turned on at night. At this time, a plurality of subjects evaluated which was brighter: the two lighting devices 10 of the present embodiment or the reference illuminance of the two reference lighting devices.

As shown in FIG. 5A, the illuminance of one of the multiple lighting devices as a reference is fixed (reference illuminance), and the illuminance value of the other two lighting devices 10 is changed from 10% lower than the reference illuminance to 7. , 6, 5, 4, 3, and 2%, and had multiple subjects evaluate each.

Therefore, by creating a lighting effect that causes light to flow from one point to another, it is possible to guide people from one point to another. For example, by changing the light in a straight line, curve, sawtooth, planar, L-shape, or diagonal shape, people gathered in a certain area can be dispersed or people can be gathered in a certain area. You can also do that.

In addition, in the lighting system 1 of the present embodiment, by combining changes in illuminance and/or color temperature and transitions of light, a lighting effect is created in which light flows from one point to another. It can enhance the effect of guiding people.

<Effect>
Next, the effects of the lighting control device 2, lighting device 10, and lighting control method in this embodiment will be explained.

As described above, the lighting control device 2 of this embodiment includes the control unit 20 that outputs a control signal to control each of the first lighting device 10a and the second lighting device 10b included in the plurality of lighting devices 10. . Further, the control signal is configured such that the luminous intensity of the light emitted by each of the first lighting device 10a and the second lighting device 10b, or the illuminance of the light emitted by each of the first lighting device 10a and the second lighting device 10b, repeats increases and decreases. is a dynamic signal. The control unit 20 then compares the maximum value Pa of the luminous intensity of the light emitted by the first lighting device 10a with the maximum value Pb of the luminous intensity of the light emitted by the second lighting device 10b, and compares the maximum value Pa of the luminous intensity of the light emitted by the first lighting device 10a. The average value of the maximum value Ra immediately after the minimum value Qa in the luminous intensity and the minimum value Qa, and the maximum value Rb immediately after the minimum value Qb in the luminous intensity of the light emitted by the second lighting device 10b. and the average value of the minimum value Qb, the maximum value of the horizontal illuminance of the illuminated surface irradiated with the light emitted by the first illuminating device 10a, and the irradiated target surface irradiated with the light emitted by the second illuminating device 10b.

A control signal having a difference of 3% or more when compared with the average value of horizontal illuminance in at least one of four comparisons is output to each of the first lighting device 10a and the second lighting device 10b. .

According to this, each of the first illuminating device 10a and the second illuminating device 10b emits dynamic light such that the luminous intensity or illuminance changes and periodically increases and decreases based on the control signal. For this reason, by irradiating the irradiated surface with light whose brightness increases and decreases periodically, the brightness of the passage can become uneven, so people pay attention to bright light. It becomes like this.

In addition, since at least one of the above four comparisons has a difference of 3% or more, the control signals sent to each of the first lighting device 10a and the second lighting device 10b are irradiated onto the irradiated surface. The brightness and irradiation range of the emitted light change. As a result, people become conscious of moving in response to these changes.

Therefore, according to this lighting control device 2, it is possible to increase the visibility and guidance to people by the light. As a result, this lighting control device 2 can realize affordance lighting.

In particular, according to this lighting system 1, by providing each of the first lighting device 10a and the second lighting device 10b, it is necessary to mount a drive mechanism on the lighting device 10 that changes the direction of light emitted by the lighting device 10 itself. Nor. Therefore, it is possible to suppress an increase in the manufacturing cost of the lighting system 1. Furthermore, since no drive mechanism is provided, there is no need to supply power to the drive mechanism. Furthermore, since there is no need to provide a drive mechanism, it is also possible to suppress an increase in the frequency of maintenance of the lighting system 1. As a result, in the lighting system 1, it is possible to suppress an increase in manufacturing costs.

Further, the lighting control method of the present embodiment includes outputting a control signal for controlling each of the first lighting device 10a and the second lighting device 10b included in the plurality of lighting devices 10, and the first lighting device 10a Comparison of the maximum value Pa of the luminous intensity of the emitted light and the maximum value Pb of the luminous intensity of the light emitted by the second lighting device 10b, and the comparison of the maximum value Pa of the luminous intensity of the light emitted by the second lighting device 10b, and the comparison of the maximum value Pa of the luminous intensity of the light emitted by the first lighting device 10a. 2. The average value of the maximum value R and the minimum value Qa, and the average value of the second maximum value R and the minimum value Qb immediately after the minimum value Qb in the luminous intensity of the light emitted by the second lighting device 10b. The maximum value of the horizontal illuminance of the illuminated surface illuminated with the light emitted by the first illumination device 10a and the maximum value of the horizontal illuminance of the illuminated surface illuminated with the light emitted by the second illumination device 10b. Comparison is a comparison between the average value of the horizontal illuminance of the illuminated surface illuminated with the light emitted by the first illuminating device 10a and the average value of the horizontal illuminance of the illuminated surface illuminated with the light emitted by the second illuminating device 10b. , outputting a control signal with a difference of 3% or more when comparing at least one of the four comparisons to each of the first lighting device 10a and the second lighting device 10b, the control signal is: A dynamic signal so that the luminous intensity of the light emitted by each of the first lighting device 10a and the second lighting device 10b or the illuminance of the light emitted by each of the first lighting device 10a and the second lighting device 10b repeats increase and decrease. be.

A control signal for controlling each of the lighting device 10a and the second lighting device 10b is output.

According to this, it is possible to brightly illuminate the irradiated surface on the other side of the passage, and gradually increase the brightness of the irradiated surface as it approaches from one side to the other side. For this reason, people who are on one side are drawn to the other side and have a tendency to move toward the brighter side, so light can guide people.

For example, when entering from the entrance of a park, amusement park, station, large-scale facility, etc., the back of the passageway extending from the entrance looks bright and stands out, so people are drawn to the bright side.

Further, in the lighting device 10 of the present embodiment, the maximum value of the output value in the control signal output to the first lighting device 10a is set as P1, which is later than the maximum value P1 over time, and the output value is transferred to the second lighting device 10b. The maximum value of the output value in the outputted control signal is set as P2, and in the control signal outputted to the first lighting device 10a, the maximum value immediately after the maximum value P1 is set as P3, and the maximum value is set as P3, which corresponds to the maximum value P1. Let S1 be the maximum value of the horizontal illuminance of the illuminated surface irradiated with the light emitted by the first illumination device 10a, and let S1 be the maximum value of the horizontal illuminance of the irradiated surface irradiated with the light emitted by the second illumination device 10b, corresponding to the maximum value P2. The maximum value of the horizontal illuminance is S2, and the maximum value of the horizontal illuminance of the irradiated surface irradiated with the light emitted by the first lighting device 10a is S3 so as to correspond to the maximum value, and the time of the maximum value P1 and the maximum value P2 The time difference between the maximum value S1 and the maximum value S2 is t1, the time difference between the maximum value P2 and the maximum value P3 is t2, the time difference between the maximum value S1 and the maximum value S2 is t3, and the maximum value S2 is the time difference. Assuming that the time difference between the maximum value S3 and the maximum value S3 is t4, if t2>t1 or t4>t3, the first lighting device 10a is better than the second lighting device 10b in at least one of the four comparisons. becomes larger.
