It is composed of a control device 30 and a terminal device 40. In the present embodiment, an example of efficiently performing eye-catching effect lighting for a person passing in the direction of the arrow shown in FIGS. 1 and 2 in front of the store (common area) will be described. To do. A frontage a is provided in front of the store, and a person passing in front of the store can see the inside of the store through the frontage a.

The lighting device 10 is a collection of lighting fixtures provided on the ceiling, wall, floor, etc. of a store and irradiates the lighting space 7 with light. In the present embodiment, the lighting device 10 is composed of a base lighting device 11 and a directing lighting device 12. (In FIG. 2, the illustration of the base lighting device 11 is omitted). The base lighting device 11 is composed of lighting fixtures 11a to 11i that perform steady lighting. The directing lighting device 12 is dynamic lighting for the purpose of catching an eye on a person passing outside the store, that is, directing lighting that repeats gradually changing at least one of the color temperature and brightness of the emitted light. It is composed of lighting fixtures 12a to 12f for performing the above. The lighting fixtures 12a to 12f constituting the effect lighting device 12 illuminate each area obtained by horizontally dividing the wall in the store, which is easy for a person passing in front of the store to see from the frontage a of the store. , They are arranged in a predetermined arrangement (here, horizontal arrangement) on the ceiling of the store. The base lighting device 11 is, for example, a downlight, a universal downlight, or the like that illuminates the lighting space 7 by direct lighting. On the other hand, the directing lighting device 12 incorporates, for example, a lighting fixture that illuminates the lighting space 7 by indirect lighting that uses reflected light from a wall or the like, an elongated lighting fixture called a light bar, or a light source incorporated into a ceiling, a wall, or the like. It is a lighting fixture called Architectural Lighting that is integrated with the building structure.

The speed detection unit 20 is a device that detects the speed of a person passing outside the illumination space 7. In the present embodiment, the speed detection unit 20 is an infrared ranging radar for detecting the walking speed of a person in the walking speed detection area sandwiched between the predetermined points A and B (see FIG. 2). , Outputs information indicating the position of the detected person (distance from the speed detection unit 20). The speed detection unit 20 is not only a device that directly detects the speed of a person, but also an event (for example, a position of a person, a moving distance) used for detecting the speed of a person, such as an infrared ranging radar. Detecting sensors are also included. That is, the speed detection unit 20 is a sensor that detects an event used to detect the speed of a person, and a calculation unit that calculates the speed of a person based on the information obtained from the sensor (control in the present embodiment). It may be a combination with the device 30).

The control device 30 is a device that causes the lighting device 10 (here, the effect lighting device 12) to perform the effect lighting when the speed detected by the speed detection unit 20 is smaller than the first threshold value. Here, the first threshold value is a value preset by the terminal device 40, for example, a value of 0.65 m / sec or more and 0.90 m / sec or less. FIG. 3 is a diagram showing experimental data useful for determining a preferred range for the first threshold, showing the speed distribution of people passing through an actual commercial facility. The horizontal axis is the walking speed (m / sec), and the vertical axis is the number of people (relative value). By associating this experimental data with the observation result of whether a person is buying around or passing through, the average speed of the person buying around is 0.65 m / sec, and the person is passing. The average speed of a person was found to be 0.90 m / sec. Therefore, by setting the first threshold value to a value of 0.65 m / sec or more and 0.90 m / sec or less, it is possible to perform directing lighting only when there is a high possibility that there are passers-by who are buying around. It will be possible. For example, by setting the first threshold value to 0.90 m / sec, the effect lighting is performed when a person passing by at the speed surrounded by the solid line in FIG. 3 is detected.

The terminal device 40 is an operation device that sends an instruction received from the user to the control device 30, and is, for example, a tablet terminal, a smartphone, or the like. For example, the user uses the terminal device 40 to perform an effect lighting mode (color temperature, brightness, repetition cycle when changing the color temperature or brightness, fade time in the change of lighting in each lighting fixture, etc.). Can be set.

FIG. 4 is a block diagram showing the configurations of the control device 30 and the lighting devices 10 (lighting fixtures 11a to 11i and 12a to 12f) constituting the lighting system 5 shown in FIG.

The control device 30 includes a lighting I / F (interface) 31, a detection I / F 32, a terminal I / F 33, and a control unit 34.

The lighting I / F31, the detection I / F32, and the terminal I / F33 are communication interfaces that communicate with the lighting fixtures 11a to 11i and 12a to 12f, the speed detection unit 20, and the terminal device 40, respectively. .. These are, for example, interfaces for wireless communication such as Wi-Fi and Bluetooth (registered trademark), or wired communication such as a serial transmission interface, and may be independent or the same one that is also used. It may be.

The control unit 34 communicates with the lighting fixtures 11a to 11i and 12a to 12f, the speed detection unit 20, and the terminal device 40, respectively, via the lighting I / F31, the detection I / F32, and the terminal I / F33. It is a controller that controls the lighting device 10. The control unit 34 is composed of, for example, a ROM in which the control program is stored, a RAM, a timer, a CPU that executes the control program, and the like.

The luminaires 11a to 11i and 12a to 12f all have the same configuration, that is, the light source 15, the lighting I / F 16, and the control unit 17.

The light source 15 is a light source capable of toning and dimming light that emits light into the illumination space 7. For example, a plurality of LEDs that emit light of three colors of RGB and currents are independently applied to each of the LEDs. It is composed of a power supply circuit and the like.

The lighting I / F 16 is a communication interface that communicates with the control device 30, and is, for example, an interface for wireless communication such as Wi-Fi and Bluetooth (registered trademark), or a wired communication such as a serial transmission interface.

The control unit 17 is a circuit that controls the light source 15 according to a control command received from the control device 30 via the lighting I / F 16. For example, a ROM in which the control program is stored, a RAM, a CPU that executes the control program, and the like. Consists of.

Next, the operation of the lighting system 5 according to the present embodiment configured as described above will be described.

FIG. 5 is a flowchart showing a basic operation (effect lighting control) of the lighting system 5 according to the embodiment. Here, a control method of the lighting device 10 is shown.

By monitoring the information sent from the speed detection unit 20, the control device 30 monitors a person who has passed the point A (see FIG. 2) from a distance in the common area in front of the store (that is, approaches the store). It is determined whether or not there is a person who comes (S10). In the present embodiment, the speed detection unit 20 is an infrared ranging radar and outputs information indicating the position of the detected person, so that the control device 30 uses the position registered in advance as the point A as a reference value. By doing so, it is determined whether or not there is a person who has passed the point A from a distance.

As a result, when the person passing through the point A is not detected (No in S10), the control device 30 determines that the effect lighting is not necessary, and causes the effect lighting device 12 to perform normal lighting (No). S14). Specifically, the control unit 34 of the control device 30 sends a control command to the effect lighting devices 12 (lighting fixtures 12a to 12f) via the lighting I / F 31, and the color temperature and brightness of the light to be illuminated. Is fixed at a predetermined value to perform normal lighting.

On the other hand, when a person who has passed the point A is detected (Yes in S10), the control device 30 uses the information sent from the speed detection unit 20 to determine the speed (walking speed) of the detected person. Calculate (S11). In the present embodiment, the speed detection unit 20 is an infrared ranging radar, and outputs information indicating the position of the detected person. Therefore, the control device 30 indicates that the person who has passed the point A has passed the point B. Is detected, and the speed is calculated from the distance and time between them.

Next, the control device 30 determines whether or not the calculated speed is smaller than the first threshold value (S12). For example, the control device 30 determines whether or not the calculated speed is smaller than 0.90 m / sec set as the first threshold value.

As a result, when the calculated speed is not smaller than the first threshold value (No in S12), the control device 30 determines that the effect lighting is not necessary, and normally illuminates the effect lighting device 12. Let (S14).

On the other hand, when the calculated speed is smaller than the first threshold value (Yes in S12), the control device 30 determines that there is a high possibility that a person who is buying around is approaching, and that person is in the store. Direct lighting is performed until the frontage a is passed (S13). Specifically, the control unit 34 of the control device 30 calculates the elapsed time predicted that the person finishes passing through the frontage a of the store by using the calculated speed. Then, by sending a control command to the effect lighting device 12 (lighting fixtures 12a to 12f) via the lighting I / F 31, at least one of the color temperature and the brightness of the emitted light is gradually adjusted for the calculated elapsed time. The production lighting that repeats the change is performed. As a result, at least while the person is passing through the frontage a of the store, that is, while the person can see the effect lighting device 12 through the frontage a of the store, the effect lighting for eye catching is performed. ..

In the production lighting, in accordance with the control command from the control device 30, the lighting fixtures 12a to 12f, for example, set the position of the light emitting a predetermined color temperature or brightness from one end to the other end in the arrangement of the lighting fixtures 12a to 12f. It emits light in an irradiation pattern that repeats moving toward it. Alternatively, the luminaires 12a to 12f emit light in an irradiation pattern in which at least one of the color temperature and the brightness of the light is repeatedly changed at the same value and at the same timing. The specific mode of the effect lighting is set in advance from the terminal device 40 (color temperature, brightness, repetition cycle when changing the color temperature or brightness, fade time in the change of lighting in each lighting fixture, etc.). It depends on.

Here, the repetition period in the effect lighting is set to, for example, the time (s) obtained by the length (m) /0.9 (m / sec) of the frontage a. As a result, while a person passing by at an average speed passes through the frontage a, one cycle of directing lighting is in the eyes of the person, and efficient eye catching can be performed.

After completing the above processes (S10 to S14), the control device 30 repeats the same processes (S10 to S14) again. Therefore, for example, if the person who is buying around continues to enter the walking speed detection area sandwiched between the points A and B from a distance one after another, all of them. The effect lighting by the effect lighting device 12 is continued until the person finishes passing through the frontage a of the store.

As described above, the lighting system 5 according to the present embodiment includes a lighting device 10 that irradiates the lighting space 7 with light, a speed detection unit 20 that detects the speed of a person passing outside the lighting space 7, and the like. A control device 30 for controlling the above is provided. When the speed detected by the speed detection unit 20 is smaller than the first threshold value, the control device 30 determines the color temperature and brightness of the light to be applied to the lighting device 10 (here, the effect lighting device 12). Control is performed to perform directing lighting that repeats changing at least one of them gradually. That is, when the speed detected by the speed detection unit 20 is not smaller than the first threshold value, the control device 30 stops the control of the effect lighting on the lighting device 10 (here, the effect lighting device 12).

As a result, when the speed of a person passing outside the lighting space 7 of the store or the like is smaller than the first threshold value, the directing lighting is performed, so that there is a possibility that there is a passerby who is buying around near the store. It is possible to perform directing lighting only at the timing when eye catching is desired, such as when it is high. Therefore, since the directing lighting is performed only at the required timing, there is a risk that the luxury of the store may be impaired or the person in the store may feel sick compared to the case where the directing lighting is always performed. Will be low. Therefore, the width and the rate of change of the color temperature in the effect lighting can be set large, and the eye-catching effect can be enhanced to improve the store entry rate.

The first threshold value is 0.65 m / sec or more and 0.90 m / sec or less.

As a result, the walking speed of the purchase around obtained from the observation of the actual passerby is used as the speed that becomes the judgment standard of the production lighting, so that there are passersby who are buying around more accurately near the store. Directed lighting is performed only when there is a high possibility.

Further, the lighting device 10 is composed of a plurality of lighting fixtures 12a to 12f arranged in a predetermined arrangement. Then, the plurality of lighting fixtures 12a to 12f emit light in an irradiation pattern in which the positions of the lights emitting a predetermined color temperature or brightness are repeatedly moved from one end to the other end in a predetermined arrangement in the effect lighting.

As a result, in the effect lighting, a plurality of lighting fixtures 12a to 12f arranged in a predetermined arrangement dynamically move the position of the light emitting a predetermined color temperature or brightness from one end to the other end in the predetermined arrangement. Illuminate. Therefore, it is possible to catch the eyes of people passing outside the lighting space 7 such as a store with a high eye-catching effect.

Alternatively, in the effect lighting, the plurality of lighting fixtures 12a to 12f emit light in an irradiation pattern in which at least one of the color temperature and the brightness of the light is repeatedly changed at the same value and at the same timing.

As a result, in the effect lighting, a plurality of lighting fixtures 12a to 12f arranged in a predetermined arrangement are dynamically illuminated with the same value and gradually changing at the same timing for at least one of the color temperature and the brightness of the light. I do. Therefore, it is possible to catch the eyes of people passing outside the lighting space 7 such as a store with a high eye-catching effect.

Further, the control method of the lighting device 10 according to the present embodiment is a control method of the lighting device 10 that irradiates the lighting space 7 with light, and includes the following steps. One is a step of acquiring information indicating the speed of a person passing outside the illumination space 7 (S11 in FIG. 5). The other is a step of controlling the lighting device 10 (effect lighting device 12) to perform effect lighting when the speed indicated by the acquired information is smaller than the first threshold value (S12 to FIG. 5). S13).

As a result, when the speed of a person passing outside the lighting space 7 of the store or the like is smaller than the first threshold value, the directing lighting is performed, so that there is a possibility that there is a passerby who is buying around near the store. It is possible to perform directing lighting only at the timing when eye catching is desired, such as when it is high. Therefore, since the directing lighting is performed only at the required timing, there is a risk that the luxury of the store may be impaired or the person in the store may feel sick compared to the case where the directing lighting is always performed. Will be low. Therefore, the width and the rate of change of the color temperature in the effect lighting can be set large, and the eye-catching effect can be enhanced to improve the store entry rate.

In the above embodiment, an example of a lighting system for directing lighting for a person passing in one direction shown in FIGS. 1 and 2 in front of the store (common area) is shown. Directed lighting may be applied to people who pass in front of them in both directions.

FIG. 6 is a layout diagram of the lighting system 5a according to the first modification of the embodiment in which directing lighting is performed for people passing in front of the store in both directions (however, in this figure, the base lighting device 11). Is omitted). The basic configuration of the lighting system 5a is the same as that of the embodiment, the same components are designated by the same reference numerals, and the description thereof will be omitted. Hereinafter, the points different from those of the embodiment will be mainly described (the same applies to the modified examples of the other embodiments).

In this modification, as shown in FIG. 6, the lighting device is composed of the first effect lighting device 13a and the second effect lighting device 13b. The first directing lighting device 13a is a lighting device that performs directing lighting for a person who passes in front of the store in the first direction, and is at a position where such a person can easily see (entering the store from the frontage a and left). Illuminates the wall located in). On the other hand, the second effect lighting device 13b is a lighting device that performs effect lighting for a person passing in the second direction opposite to the first direction in front of the store, and is a position easily noticed by such a person. Illuminate (the wall located on the right when entering the store from the frontage a).

Further, the speed detection unit is also composed of a first speed detection unit 20a and a second speed detection unit 20b. The first speed detection unit 20a is a device for detecting the walking speed of a person in the first walking speed detection area sandwiched between points A and B for a person passing in front of the store in the first direction. Yes, for example, it is arranged at the right end of the frontage a when viewed from the outside of the store. On the other hand, the second speed detection unit 20b is for detecting the walking speed of a person in the second walking speed detection area sandwiched between the points C and D for the person passing in the second direction in front of the store. It is a device, and is arranged at the left end of the frontage a when viewed from the outside of the store, for example.

According to the lighting system 5a according to the present modification having such a configuration, the control device 30 is the first effect lighting device 13a when the speed detected by the first speed detection unit 20a is smaller than the first threshold value. On the other hand, the same effect lighting as in the above embodiment is performed. At the same time, when the speed detected by the second speed detection unit 20b is smaller than the first threshold value, the control device 30 gives the second effect lighting device 13b the same effect illumination as in the above embodiment. To do.

As a result, for people who pass in front of the store in both directions, directing lighting is performed only at the timing when eye catching is desired, such as when there is a high possibility that there are passersby who are buying around near the store. ..

Further, in the above-described embodiment and the first modification, the effect lighting control shown in FIG. 5 is repeated, but the effect lighting control does not necessarily have to be repeated, and when a situation occurs in which the effect lighting control is desired to be suppressed. May stop the effect lighting control. Hereinafter, a lighting system according to a modified example (second modified example to fourth modified example) of the above-described embodiment to which a control for stopping the effect lighting control is added will be described.

FIG. 7 is a flowchart showing the operation of the lighting system according to the second modification of the embodiment. In this modified example, when there is no person walking at low speed in front of the store, the effect lighting control shown in FIG. 5 is stopped. Therefore, in parallel with (or in addition to) the effect lighting control shown in FIG. 5, the following control shown in FIG. 7 is executed.

The control device 30 determines whether or not there is a person passing in front of the store at a speed equal to or higher than the first threshold and lower than the second threshold (S20). For example, the control device 30 determines whether or not there is a person passing by at a speed of 1.5 m / sec or less in the walking speed detection area based on the information from the speed detection unit 20.

As a result, if it is determined that there is (Yes in S20), the control device 30 performs the effect lighting controls S10 to S14 shown in FIG. 5 (S21). That is, the control device 30 controls the lighting device 10 (here, the effect lighting device 12) to perform the effect lighting only when the speed detected by the speed detection unit 20 is smaller than the first threshold value. To do.

On the other hand, if it is determined that there is not (No in S20), the control device 30 stops the effect lighting controls S10 to S14 shown in FIG. 5 (S22). That is, the control device 30 performs normal illumination corresponding to step S14 in FIG.

The control device 30 repeats the above processes S20 to S22 (for example, it is executed once every 10 minutes).

As described above, in the present modification, when the speed detection unit 20 does not detect a person passing by at a speed equal to or higher than the first threshold value and lower than the second threshold value, the control device 30 causes the lighting device 10 to perform effect lighting. Stop control.

As a result, when there is no person walking at low speed in front of the store, that is, when there is almost no possibility that there is a person who is buying around, the control of the effect lighting is stopped. Therefore, more reliably, the directing lighting is performed only at the timing when eye catching is desired, such as when there is a high possibility that there is a passerby who is buying around near the store.

FIG. 8 is a layout diagram of the lighting system 5b according to the third modification of the embodiment (however, in this figure, the illustration of the base lighting device 11 is omitted). A first person detection unit 22 for detecting the number of people in the lighting space 7 (here, in the store) is added to the configuration of the above embodiment. In this modification, the first person detection unit 22 is, for example, a camera installed in the center of the ceiling of the store to detect the number of people in the store, and controls an image of the people in the store. Output to device 30. The first number detection unit 22 includes not only a device that directly detects the number of people, but also a sensor that acquires an event (for example, an image) used for detecting the number of people, such as a camera. .. That is, the first number detection unit 22 is a sensor that acquires an event used to detect the number of people, and a calculation unit that calculates the number of people based on the information obtained from the sensor (in the present embodiment). , And the control device 30) may be combined.

FIG. 9 is a flowchart showing the operation of the lighting system 5b according to this modification. In this modified example, when there are many people in the store, the effect lighting control shown in FIG. 5 is stopped. Therefore, in parallel with (or in addition to) the effect lighting control shown in FIG. 5, the following control shown in FIG. 9 is executed.

The control device 30 determines whether or not the number of people in the store (that is, the number of people detected by the first person detection unit 22) is larger than the third threshold value (S30). For example, the control device 30 detects the number of people in the store by performing a person extraction process or the like from the image sent from the first person detection unit 22, and the number of detected people is a third threshold value (for example,). Judge whether it is larger than 5 people).

As a result, when it is determined that the number of people in the store is larger than the third threshold value (Yes in S30), the control device 30 stops the effect lighting controls S10 to S14 shown in FIG. 5 (S31). That is, the control device 30 performs normal illumination corresponding to step S14 in FIG.

On the other hand, when it is determined that the number of people in the store is not larger than the third threshold value (No in S30), the control device 30 performs the effect lighting controls S10 to S14 shown in FIG. 5 (S32). That is, the control device 30 controls the lighting device 10 (here, the effect lighting device 12) to perform the effect lighting only when the speed detected by the speed detection unit 20 is smaller than the first threshold value. To do.

The control device 30 repeats the above processes S30 to S32 (for example, it is executed once every 10 minutes).

As described above, in this modification, the first person detection unit 22 for detecting the number of people in the lighting space 7 is provided, and the control device 30 has the number of people detected by the first person detection unit 22. When it is larger than the three threshold values, the control for causing the lighting device 10 to perform the effect lighting is stopped.

As a result, when the number of people in the lighting space 7 of the store or the like is large, the control of the directing lighting is stopped, so that the people in the store are sickened by changing the lighting for a long time. Is suppressed.

FIG. 10 is a layout diagram of the lighting system 5c according to the fourth modification of the embodiment (however, in this figure, the illustration of the base lighting device 11 is omitted). A second person detection unit 24 for detecting the number of people within a predetermined distance from the lighting device 10 (here, the effect lighting device 12) is added to the configuration of the above embodiment. In this modification, the second person detection unit 24 is, for example, a camera installed near the effect lighting device 12 in order to detect the number of people near the effect lighting device 12, and is derived from the effect lighting device 12. An image of a person within a predetermined distance (2 m or the like) is output to the control device 30. The second number detection unit 24 includes not only a device that directly detects the number of people, but also a sensor that acquires an event (for example, an image) used for detecting the number of people, such as a camera. .. That is, the second number detection unit 24 is a sensor that acquires an event used to detect the number of people, and a calculation unit that calculates the number of people based on the information obtained from the sensor (in the present embodiment). , And the control device 30) may be combined.

FIG. 11 is a flowchart showing the operation of the lighting system 5c according to this modification. In this modification, when there are many people within a predetermined distance from the lighting device 10 (here, the effect lighting device 12), the effect lighting control shown in FIG. 5 is stopped. Therefore, in parallel with (or in addition to) the effect lighting control shown in FIG. 5, the following control shown in FIG. 11 is executed.

The control device 30 determines whether or not the number of people within a predetermined distance range from the effect lighting device 12 (that is, the number of people detected by the second person detection unit 24) is larger than the fourth threshold value. (S40). For example, the control device 30 detects and detects the number of people within a predetermined distance from the effect lighting device 12 by performing a person extraction process or the like from the image sent from the second person detection unit 24. It is determined whether or not the number of people who have done so is larger than the fourth threshold value (for example, 3 people).

As a result, when it is determined that the number of people within a predetermined distance range from the effect lighting device 12 is larger than the fourth threshold value (Yes in S40), the control device 30 controls the effect lighting shown in FIG. Controls S10 to S14 are stopped (S41). That is, the control device 30 performs normal illumination corresponding to step S14 in FIG.

On the other hand, when it is determined that the number of people within a predetermined distance range from the effect lighting device 12 is not larger than the fourth threshold value (No in S40), the control device 30 uses the effect lighting shown in FIG. Controls S10 to S14 are performed (S42). That is, the control device 30 controls the effect lighting device 12 to perform the effect lighting only when the speed detected by the speed detection unit 20 is smaller than the first threshold value.

The control device 30 repeats the above processes S40 to S42 (for example, it is executed once every 10 minutes).

As described above, in this modification, the second person detection unit 24 for detecting the number of people within a predetermined distance from the lighting device 10 is provided. The control device 30 stops the control for causing the effect lighting device 12 to perform the effect lighting when the number of people detected by the second person detection unit 24 is larger than the fourth threshold value.

As a result, the control of the effect lighting is stopped when there is a person near the effect lighting device 12, so that the person in the store is more surely sickened by performing the changing lighting for a long time. It is suppressed that it is stored.

The control method of the lighting system and the lighting device according to the present invention has been described above based on the embodiments and modifications, but the present invention is not limited to these embodiments and modifications. As long as the gist of the present invention is not deviated, various modifications that can be conceived by those skilled in the art are applied to the present embodiment and the modified examples, and other embodiments constructed by combining some components in the embodiments and the modified examples. Is also included within the scope of the present invention.

For example, the present invention also includes a form in which all the functions of the first modification, the second modification, the third modification, and the fourth modification are added to the above embodiment.

In addition, if the store is a store that targets women such as apparel and general stores, a camera that takes pictures of people passing by in front of the store is installed, and depending on the attributes of the passersby (female or male), The control of the effect lighting may be executed / stopped. That is, when the passerby is a woman, the effect lighting control shown in FIG. 5 may be executed, and when the passerby is a man, the effect lighting control shown in FIG. 5 may be stopped.

As a result, especially in the case of stores targeting women, which are adjacent to transportation facilities such as stations, since a relatively large number of men are included in the passersby who use the station, control that takes into account such attributes. This enables highly accurate control narrowed down to the intended target. When determining the attributes of a passerby using a camera or the like, it is possible to consider the privacy of the person by discarding the image after making the determination.

In addition, using the control device 30 or the server device connected to the control device 30, the relationship between various conditions (time zone of the day, mode of the effect lighting) and the increase / decrease in the store entry rate due to the execution of the effect lighting The data shown may be accumulated and analyzed. Then, the directing lighting may be executed only when the conditions that are likely to increase the store entry rate are met. This makes it possible to perform directing lighting only at the timing when eye catching is desired with high efficiency.

Further, in the above-described embodiment and modification, the space inside the store is exemplified as the lighting space 7, but the lighting space 7 is not limited to this. As long as it is a lighting space for the purpose of catching the eyes of passers-by, it may be a space in various facilities such as an exhibition room, a sports gym, and a classroom.

Further, in the above-described embodiment and modification, the base lighting device 11 is a downlight or the like that illuminates the lighting space 7 by direct lighting, and the directing lighting device 12 is a downlight or the like that illuminates the lighting space 7 by indirect lighting. , Not limited to these lighting modes and appliances. Both the base lighting device 11 and the effect lighting device 12 may be either direct lighting or indirect lighting, or may be other lighting modes and appliances such as a base light.

Further, in the above-described embodiment and modified example, in determining whether or not the speed of the passerby is smaller than the first threshold value, the control device 30 detects that the person who has passed the point A has passed the point B. , The speed calculated from the distance and time between them and the first threshold value were compared, but the present invention is not limited to this. For example, if the point B is not reached even after a predetermined time has passed after passing the point A, it may be determined that the speed of the passerby is smaller than the first threshold value. In the present invention, "when the speed of a person is detected and the speed of the detected person is smaller than the first threshold value" means that the speed is smaller than the first threshold value without directly detecting the speed. The case of detecting that is also included. By such a detection method, it is not necessary to measure the speed of all passersby, so that the processing load on the control device 30 is reduced.

Further, in the above-described embodiment and modified example, the points B and D indicating the end points of the walking speed detection area are located at a position separated by a predetermined distance upstream from the frontage a of the store in the traffic direction. Not limited. It may be the end on the upstream side in the traffic direction at the frontage a of the store.

Further, in the above-described embodiment and modified example, when it is determined that the walking speed of the person in the walking speed detection area is smaller than the first threshold value, the effect lighting is started, but the start timing of the effect lighting is set to this. Not limited. A sensor for detecting a person may be provided at the upstream end of the frontage a of the store in the traffic direction, and when the sensor detects a person, the effect lighting may be started. As a result, when a person passing in front of the store reaches the frontage a, the directing lighting is surely started.

Further, in the above-described embodiment and modification, the speed detection unit 20 is an infrared ranging radar that outputs information indicating the position of the detected person, but the speed detection unit 20 is not limited to this. Other sensors such as a camera and an ultrasonic sensor may be used as long as they are sensors that acquire information (speed, position, moving distance, etc.) necessary for identifying the speed of a person. Similarly, the first person detection unit 22 and the second person detection unit 24 are cameras that output images taken to detect the number of people, but are not limited thereto. As long as it is a sensor that acquires information necessary for identifying the number of people, it may be another sensor such as a motion sensor.

Further, in the above-described embodiment and modification, the control device 30 and the terminal device 40 are separate devices, but they may be integrated as in a lycon (light control device).

Further, in the above-described embodiment and modified example, as directing lighting, the position of light such as a predetermined color temperature may be moved or a plurality of times with a period of time during which a person passing by at an average speed passes through the frontage a. The lighting equipment was gradually changed at the same color temperature and at the same timing. However, the mode of directing lighting is not limited to such a cycle of lighting and a variation mode. Since the appearance of the illumination light differs depending on the ambient brightness and the color temperature, the illumination cycle may be appropriately determined depending on the surrounding conditions. In addition, the mode of change such as the change width of the color temperature may be appropriately determined depending on the characteristics of the store and the like.

Further, in the above-described embodiment and modification, the lighting fixtures 11a to 11i and 12a to 12f all have the same configuration, but are not limited thereto. For example, the lighting fixtures 11a to 11i constituting the base lighting device 11 may include a light source having a fixed color temperature, unlike the effect lighting device 12.
