[Effects of the Invention]

[0012] According to the present disclosure, it is possible to simulate in advance the effects that can be expected when a lighting fixture capable of implementing affordance lighting is introduced. [Brief explanation of the drawings]

[0013] [Figure 1] FIG. 1 is a block diagram showing a lighting simulation system according to an embodiment. [Figure 2] FIG. 2 is a diagram showing various data. [Figure 3] FIG. 3 is a diagram showing the results of the simulation. [Figure 4] FIG. 4 is a flowchart showing an example of the operation of the lighting control simulator according to the embodiment. [Figure 5] FIG. 5 is a block diagram showing a lighting simulation system according to a modified example of the embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0014] The embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component placement and connection configurations, steps, and step order shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Furthermore, among the components in the following embodiments, components not described in independent claims are described as optional components.

[0015] In addition, each drawing is a schematic diagram and is not necessarily an exact illustration. In addition, the same components are denoted by the same reference numerals in each drawing.

[0016] Hereinafter, the embodiments will be specifically described with reference to the drawings.

[0017] (Embodiment) <Summary> For example, by implementing affordance lighting by placing multiple lighting fixtures in a passageway, plaza, facility, etc. and adjusting the lighting mode of the light emitted from the lighting fixtures, it is possible to expect the following effects: guiding pedestrians in a predetermined direction, gathering guided pedestrians in a predetermined area, or guiding pedestrians gathered in a predetermined area to disperse. For example, the savanna effect is known, which states that pedestrians are guided to areas with brighter vertical illuminance than areas with darker vertical illuminance. Since affordance lighting mainly illuminates the ground, it is strictly different from the savanna effect, which is related to vertical illuminance. However, by changing the control state of a predetermined illumination pattern of light in order to achieve an effect similar to the savanna effect and influencing pedestrians' emotions through the savanna effect, it is possible to guide pedestrians.

[0018] Here, the illumination pattern refers to a scene in which affordance lighting is implemented, which is different from a scene in which the lighting is simply always on. An illumination pattern in which affordance lighting is implemented is realized, for example, by a dynamic control signal that repeatedly increases and decreases the light output. Changing the control state of the illumination pattern refers to executing affordance lighting from a scene in which the lighting is simply always on or off, executing a different affordance lighting from affordance lighting, or returning to a scene in which the lighting is simply always on or off. Increasing or decreasing the light output includes increasing or decreasing the luminous intensity and illuminance of light emitted by lighting fixtures, increasing or decreasing the luminous intensity and illuminance of light irradiated onto an irradiated surface, changing the color temperature or chromaticity of light emitted by lighting fixtures, and changing the color temperature or chromaticity of light irradiated onto an irradiated surface. An example of affordance lighting is lighting in which multiple lighting fixtures are arranged along a corridor, and the illuminance and chromaticity of the light irradiated onto an irradiated surface (light-irradiated area) gradually change from one side of the corridor to the other or from the other side to one side of the corridor.

[0019] <Configuration and Functions> A lighting simulation system 1 having a lighting control simulator 10 according to the following embodiment will be described with reference to FIGS. 1 to 3. FIG.

[0020] Fig. 1 is a block diagram showing a lighting simulation system 1 according to an embodiment. Fig. 2 is a diagram showing various data. Fig. 3 is a diagram showing the results of a simulation. In Fig. 3, pedestrians are indicated by black or white circles, and pedestrian flow is indicated by dashed or dashed lines.

[0021] As shown in Fig. 1, the lighting simulation system 1 of this embodiment is a system that simulates how the flow of pedestrians changes by virtually providing affordance lighting that can guide pedestrians (people) by adjusting the lighting mode of light emitted from lighting fixtures. The lighting simulation system 1 is, for example, a PC (Personal Computer) equipped with a display unit 20 such as a liquid crystal display and an input unit 5 such as a keyboard, or a dedicated tablet terminal.

[0022] Such a lighting simulation system 1 executes a simulation of a location where it is desired to guide people, such as a store, a park, an amusement park, a station, or a large-scale facility.

[0023] The lighting simulation system 1 includes an input unit 5, a lighting control simulator 10, and a display unit 20.

[0024] [Input section 5] The input unit 5 is an input interface such as a keyboard or a pointing device that can input various data to the lighting control simulator 10. The various data include at least road map data shown in Fig. 1, and pedestrian data, lighting fixture specification data, and lighting irradiation pattern data as shown in Fig. 2(a) to (e). Furthermore, the various data may include pedestrian traffic frequency data and vehicle traffic frequency data.

[0025] The road map data represents the planned installation locations of lighting fixtures and the surrounding areas of the planned installation locations. Virtual lighting fixtures can be placed in the road map data and superimposed on the road map data. Since the road map data indicates location information such as latitude and longitude, when virtual lighting fixtures are placed on the road map data, the placed location information can be linked to the virtual lighting fixtures.

[0026] The pedestrian data represents the attributes of the pedestrian. The pedestrian attributes include the pedestrian's gender, age, occupation, etc. For example, the pedestrian attributes may be a student going to or from school, an office worker commuting to work, shopping, taking a walk, a delivery person, a police officer on patrol, etc.

[0027] In addition to pedestrian data, the various data may include moving vehicle attribute data. The moving vehicle attribute data represents attributes of a moving vehicle. The moving vehicle attributes include the vehicle type, vehicle form, etc. For example, the moving vehicle attributes include bus, private car, taxi, commercial delivery vehicle, ambulance, police car, fire engine, etc.

[0028] The lighting fixture specification data indicates specifications related to the illumination of the lighting fixture to be installed at the planned installation location, including the color temperature, installation position, product number, etc. of the lighting fixture.

[0029] The lighting irradiation pattern data represents multiple irradiation patterns for emitting light from a lighting fixture. The irradiation pattern is composed of a combination of settings for the illuminance of the irradiation point when the lighting fixture shines light on the illuminated surface, whether the light emitted by the lighting fixture blinks, the time interval for blinking, the light color of the lighting fixture, whether the irradiation point is fixed or moving, and if the irradiation point is moving, whether the irradiation position range and movement speed are fixed or variable. In addition, the lighting fixture to be used can be specified when setting the irradiation pattern. Therefore, the lighting irradiation pattern data also includes the lighting fixture to be used.

[0030] The pedestrian traffic frequency data indicates time periods when the pedestrian traffic frequency (traffic volume) is higher than a reference value. For example, the pedestrian traffic frequency data indicates the pedestrian traffic frequency for each time period when the traffic frequency at a specified point is higher than a reference value, and may include only time periods with a traffic frequency equal to or higher than the reference value. The reference value is a preset value and can be changed as desired.

[0031] The vehicle traffic frequency data represents time periods when the frequency of vehicle traffic (traffic volume) other than pedestrians is higher than a reference value. For example, the vehicle traffic frequency data represents the frequency of vehicle traffic for each time period when the traffic frequency at a specified point is higher than a reference value, and may include only time periods with a traffic frequency equal to or higher than the reference value. The reference value is a preset value and can be changed as desired.

[0032] It should be noted that pedestrian traffic frequency data and vehicle traffic frequency data may or may not be input to the input unit 5.

[0033] As shown in FIG. 1, the input unit 5 outputs various input data to the lighting control simulator 10.

[0034] [Lighting control simulator 10] The lighting control simulator 10 acquires various data from the input unit 5. The lighting control simulator 10 stores the acquired various data in the corresponding first to sixth storage units 11a to 11f.

[0035] The lighting control simulator 10 simulates the effect of a lighting fixture on pedestrians according to the planned installation location of the lighting fixture and the situation (various data) of the surrounding area of ​​the planned installation location. For example, the lighting control simulator 10 simulates the effect of a lighting fixture on pedestrians by placing a virtual lighting fixture capable of performing affordance lighting at the planned installation location on road map data, or by inputting various data such as the planned installation location and the situation of the surrounding area of ​​the planned installation location.

[0036] Specifically, the lighting control simulator 10 includes a first storage unit 11a to a sixth storage unit 11f, and a processing unit 12.

[0037] 1 and 2, the first storage unit 11a stores road map data. When new road map data is acquired, the first storage unit 11a can update and store the road map data.

[0038] The second storage unit 11b stores pedestrian data for each of a plurality of pedestrians. When new pedestrian data is acquired, the second storage unit 11b can update and store the pedestrian data.

[0039] The third storage unit 11c stores the lighting fixture specification data for each of the lighting fixtures. When the lighting fixture specification data is acquired, the third storage unit 11c can update the lighting fixture specification data.

[0040] The fourth storage unit 11d stores illumination irradiation pattern data. When illumination irradiation pattern data is acquired, the fourth storage unit 11d can update and store the illumination irradiation pattern data.

[0041] The fifth storage unit 11e stores pedestrian traffic frequency pattern data. When the pedestrian traffic frequency pattern data is acquired, the fifth storage unit 11e can update and store the pedestrian traffic frequency pattern data.

[0042] The sixth storage unit 11f stores vehicle traffic frequency pattern data. When the vehicle traffic frequency pattern data is acquired, the sixth storage unit 11f can update and store the vehicle traffic frequency pattern data.

[0043] The first storage unit 11a to the sixth storage unit 11f may be integrated into one storage unit.

[0044] Furthermore, various data in first memory unit 11a to sixth memory unit 11f are updated by input from input unit 5. At least road map data, pedestrian data, lighting device specification data, and lighting irradiation pattern data can be updated by periodically or temporarily (manually) downloading them from a predetermined external device 9. Furthermore, various data in fifth memory unit 11e and sixth memory unit 11f can be updated by periodically or temporarily downloading them from a predetermined external device 9.

[0045] The processing unit 12 can acquire the results of a simulation that predicts how the flow of pedestrians will change in the planned installation location and the surrounding area.

[0046] Specifically, the processing unit 12 virtually sets where on the road map data the lighting fixtures will be installed based on the various data input to the input unit 5. After virtually setting where on the road map data the lighting fixtures will be installed, the processing unit 12 uses at least the lighting fixture specification data and / or the lighting irradiation pattern data to obtain the results of a simulation that predicts how the flow of pedestrians will change at the planned installation location and in the surrounding area.

[0047] For example, after virtually setting the locations on road map data for installing lighting fixtures, the processing unit 12 executes a simulation using an artificial intelligence simulation algorithm based on at least the position information of the virtually installed lighting fixtures, lighting fixture specification data, and / or lighting irradiation pattern data to predict how pedestrian flow will change at the planned installation location and the surrounding area, and obtains the simulation results. The artificial intelligence simulation algorithm may be a learning model obtained by machine learning of past sample data. The past sample data may be training data that has learned changes in pedestrian flow based on at least the virtual installation locations of the lighting fixtures and the lighting fixture specification data and / or lighting irradiation pattern data. The artificial intelligence simulation algorithm may be trained using one or more known statistical classification techniques. Furthermore, the processing unit 12 may update the simulation algorithm by receiving feedback from the simulation results.

[0048] Furthermore, when pedestrian traffic frequency data and vehicle traffic frequency data are further input as various data from the input unit 5, the processing unit 12 may acquire the results of a simulation that predicts how pedestrian flow will change at the planned installation location and the surrounding area. In this case, once the processing unit 12 has virtually set where on the road map data to install the lighting fixture, it may use an artificial intelligence simulation algorithm to execute a simulation that predicts how pedestrian flow will change at the planned installation location and the surrounding area based on the lighting fixture specification data and / or lighting irradiation pattern data, the pedestrian traffic frequency data, and the vehicle traffic frequency data, and acquire the results of the simulation.

[0049] Then, the processing unit 12 outputs the acquired simulation results to the display unit 20.

[0050] The processing unit 12 also acquires a simulation result of what proportion of a plurality of pedestrians can be guided when the irradiation pattern is executed, compared to the movement of pedestrians when the irradiation pattern is not executed. That is, the processing unit 12 acquires both the result of a simulation predicting how the flow of pedestrians will change (hereinafter referred to as a first simulation result) and the result of a simulation of what proportion of a plurality of pedestrians can be guided (hereinafter referred to as a second simulation result). The processing unit 12 outputs these two simulation results to the display unit 20.

[0051] Furthermore, the processing unit 12 may cause the display unit 20 to display an image that graphs the number of customers in a store before and after the introduction of a lighting device capable of implementing affordance lighting, as shown in Fig. 3. Furthermore, the processing unit 12 may cause the display unit 20 to display, as a result of the simulation, the change in the flow of pedestrians before the introduction of affordance lighting and the change in the flow of pedestrians after the introduction of affordance lighting.

[0052] [Display section 20] 1 and 3, the display unit 20 is a display such as a liquid crystal display or an organic EL (Electro Luminescence) display. The display unit 20 acquires the results of the simulation from the processing unit 12. When the display unit 20 acquires a first simulation result, it displays the first simulation result. When the display unit 20 acquires a second simulation result, it displays the second simulation result. When the display unit 20 acquires both the first simulation result and the second simulation result, it may display the first simulation result and the second simulation result in combination.

[0053] <Processing operation> The processing operations of the lighting control simulating device 10 and the lighting control simulating method according to this embodiment will be described.

[0054] (Example of operation) This operation example will be described with reference to Fig. 4. Fig. 4 is a flowchart showing an operation example of the lighting control simulator 10 according to the embodiment.

[0055] 4, first, the lighting simulation system 1 is started up and a simulation program of the lighting simulation system 1 is executed, whereby a user interface that allows various data to be input is displayed on the display unit 20.

[0056] Various data are input to the input unit 5 (S11). That is, the input unit 5 receives at least road map data, pedestrian data, lighting fixture specification data, and lighting irradiation pattern data as the various data. The input unit 5 may further receive pedestrian traffic frequency data and vehicle traffic frequency data as the various data. The input unit 5 outputs the input various data to the lighting control simulator 10.

[0057] Next, the worker uses the input unit 5 to virtually place the lighting fixtures on the road map data displayed on the display unit 20. As a result, the processing unit 12 virtually sets where on the road map data the lighting fixtures should be installed, based on the various data input to the input unit 5 and the virtual placement of the lighting fixtures on the road map data (S12).

[0058] Next, after virtually setting where on the road map data the lighting fixtures will be installed, the processing unit 12 uses at least the lighting fixture specification data and / or the lighting irradiation pattern data to obtain a simulation result predicting how the flow of pedestrians will change at the planned installation location and the surrounding area (S13). For example, the processing unit 12 uses an artificial intelligence simulation algorithm based on the position information of the lighting fixtures virtually installed on the road map data and the lighting fixture specification data and / or the lighting irradiation pattern data to execute a simulation predicting how the flow of pedestrians will change at the planned installation location and the surrounding area, and obtains the simulation result (first simulation result).

[0059] The processing unit 12 may also acquire a result (second simulation result) of a simulation of what proportion of multiple pedestrians can be guided when the irradiation pattern is executed, compared to when the irradiation pattern is not executed. That is, the processing unit 12 may acquire both the first simulation result and the second simulation result. The processing unit 12 may output the results of these two simulations to the display unit 20.

[0060] Next, the processing unit 12 outputs the results of the simulation to the display unit 20 (S14). As shown in FIG. 3, when the display unit 20 acquires the results of the simulation from the processing unit 12, it displays the acquired results of the simulation. When only the first simulation result is acquired, the display unit 20 displays only the first simulation result. When the display unit 20 further acquires the second simulation result, the display unit 20 may display the first simulation result and the second simulation result in combination. Furthermore, when only the second simulation result is acquired, the display unit 20 may display only the second simulation result.

[0061] Then, the lighting simulation system 1 ends the processing operation of the flowchart shown in FIG.

[0062] <Action and effect> Next, the effects of the lighting control simulator 10 and the lighting control simulating method according to this embodiment will be described.

[0063] As described above, the lighting control simulator 10 according to this embodiment is a lighting control simulator 10 that simulates the effect of lighting fixtures on pedestrians depending on the conditions of the planned installation locations of the lighting fixtures and the surrounding areas of the planned installation locations, and is equipped with a processing unit 12 that receives as input road map data representing the planned installation locations of the lighting fixtures and the surrounding areas, pedestrian data representing pedestrian attributes, lighting fixture specification data representing specifications related to the illumination of the lighting fixtures to be installed at the planned installation locations, and lighting illumination pattern data representing multiple illumination patterns for emitting light from the lighting fixtures, and virtually sets where on the road map data the lighting fixtures will be installed, and obtains simulation results that predict how the flow of pedestrians will change at the planned installation locations and in the surrounding areas by using the lighting fixture specification data and / or the lighting illumination pattern data.

[0064] This allows for the input of the planned installation location, the surrounding area of ​​the planned installation location, pedestrian data, lighting fixture specification data, and lighting irradiation pattern data, etc., to simulate the flow of pedestrians when lighting fixtures capable of implementing affordance lighting are introduced.

[0065] Therefore, the lighting control simulator 10 can simulate in advance the effects that can be expected when a lighting fixture capable of implementing affordance lighting is installed.

[0066] Furthermore, the lighting control simulating method according to this embodiment is a lighting control simulating method that simulates the effect that lighting fixtures have on pedestrians depending on the conditions of the planned installation locations of the lighting fixtures and the surrounding areas of the planned installation locations, and includes inputting road map data that represent the planned installation locations of the lighting fixtures and the surrounding areas, pedestrian data that represent pedestrian attributes, lighting fixture specification data that represent specifications related to the illumination of the lighting fixtures that are planned to be installed at the planned installation locations, and lighting illumination pattern data that represent multiple illumination patterns for emitting light from the lighting fixtures, virtually setting where on the road map data the lighting fixtures will be installed, and obtaining simulation results that predict how the flow of pedestrians will change at the planned installation locations and the surrounding areas by using the lighting fixture specification data and / or the lighting illumination pattern data.

[0067] This provides the same effects as those described above in the lighting control simulation method.

[0068] Furthermore, in the lighting control simulator 10 according to this embodiment, the processing unit 12 also acquires simulation results as to what percentage of the multiple pedestrians can be guided when the irradiation pattern is executed, compared to the movement of the multiple pedestrians when the irradiation pattern is not executed.

[0069] This allows users to know the expected effects of affordance lighting on guiding pedestrian flow as a basis for making decisions before installing lighting fixtures. If the expected effects are lower than expected, users can carefully consider the placement of lighting fixtures and the selection of illumination patterns that will meet their expectations before installing the lighting fixtures.

[0070] Furthermore, the lighting control simulator 10 of this embodiment acquires simulation results that predict how pedestrian traffic will change at the planned installation location and in the surrounding area by further inputting pedestrian traffic frequency data that indicates time periods when the pedestrian traffic frequency is higher than a reference value and vehicle traffic frequency data that indicates time periods when the traffic frequency of vehicles other than pedestrians is higher than a reference value.

[0071] For example, if a simulation is performed for all time periods, the processing load on the lighting control simulator 10 increases, and it may take a long time to obtain the results of the simulation.

[0072] However, according to this embodiment, for example, by narrowing down the simulation to dangerous time periods when traffic volume is heavy and traffic accidents are likely to occur, it becomes possible to perform a simulation in a shorter time.

[0073] In particular, in the case of a system that relies on the calculations of a remote external device 9 such as a cloud server for the simulation, limiting the calculations to only the most important ones makes it possible to suppress overloads on calculations and communications.

[0074] In addition, in the lighting control simulator 10 according to this embodiment, the irradiation pattern is configured by combining settings for the illuminance of the irradiation point, whether to blink or not, the time interval for blinking, the light color, and, if the irradiation point moves, settings for the irradiation position range and the moving speed, which are fixed or variable. The lighting fixture to be used can be specified when setting the irradiation pattern.

[0075] This allows various illumination patterns to be generated by changing the settings. Therefore, even if pedestrians have diverse preferences, illumination patterns tailored to each pedestrian can be provided. As a result, pedestrian data can be enriched, making it possible to obtain more accurate simulation results.

[0076] Furthermore, the lighting control simulator 10 according to this embodiment can periodically or ad hoc download and update at least the road map data, pedestrian data, lighting fixture specification data, and lighting irradiation pattern data from a predetermined external device 9.

[0077] This allows the latest data to be automatically or temporarily updated, thereby preventing a decrease in the accuracy of the simulation results and making the results more realistic.

[0078] (Modification of the embodiment) The lighting control simulator 10a and lighting control simulating method of this modification differ from the lighting control simulator and lighting control simulating method of the embodiment in that a communication unit 12a is used instead of a processing unit. The configurations and functions of the lighting control simulator 10a and lighting control simulating method of this modification that are the same as those of the lighting control simulator 10 and lighting control simulating method of the embodiment are designated by the same reference numerals, and detailed descriptions of the configurations and functions will be omitted.

[0079] <Configuration and Functions> A lighting control simulator 10a and a lighting control simulation method according to this modification will be described with reference to FIG.

[0080] FIG. 5 is a block diagram showing a lighting control simulator 10a according to a modified example of the embodiment.

[0081] In this modification, the lighting control simulator 10a includes a communication unit 12a in addition to the first to sixth storage units 11a to 11f.

[0082] The communication unit 12a transmits the various data input to the input unit 5 to an external device 9 such as a cloud server. That is, the communication unit 12a requests the external device 9 to perform a simulation to predict how pedestrian flow will change at the planned installation location and the surrounding area, based on the various data input to the input unit 5 and the virtual installation position (position information) of the lighting fixture on the road map data input to the input unit 5. The external device 9 executes a simulation to predict how pedestrian flow will change at the planned installation location and the surrounding area, and transmits the results of the executed simulation to the communication unit 12a. In this way, the communication unit 12a receives (acquires) the results of the simulation from the external device 9. The communication unit 12a outputs the acquired results of the simulation to the display unit 20.

[0083] <Action and effect> Next, the effects of the lighting control simulator 10a and the lighting control simulating method according to this modification will be described.

[0084] As described above, in the lighting control simulator 10a according to this modification, the processing unit is the communication unit 12a that can communicate with the external device 9. Then, a request is made to the external device 9 for a simulation that predicts how the flow of pedestrians will change at the planned installation location and in the surrounding area, and the results of the requested simulation are obtained from the external device 9.

[0085] According to this, by having the external device 9 analyze the effect of the irradiation pattern on pedestrians, it is possible to suppress an increase in the processing load on the lighting control simulator 10a.

[0086] (Other variations, etc.) The present disclosure has been described above based on the embodiments and modified examples of the embodiments, but the present disclosure is not limited to these embodiments and modified examples of the embodiments.

[0087] For example, the lighting control simulating device and the lighting control simulating method according to the present embodiment and the modified examples of the embodiment may be realized by a program that causes a computer to execute the lighting control simulating method. This program may be stored in a storage unit provided in the lighting control simulating device.
