[0015] (Embodiment) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0016] (First embodiment) 1 is a block diagram showing an illumination model processing device according to a first embodiment of the present invention. This embodiment acquires property information and lighting fixture information, and enables easy generation of materials related to lighting design, particularly 3D image models.

[0017] 1, the lighting model processing device 10 includes an information management unit 11, a lighting fixture information search unit 12, a display data generation unit 13, a display control unit 14, a lighting fixture selection unit 15, a specification setting information storage unit 15a, a model generation unit 16, and a lighting design information storage unit 16a. The information management unit 11, the lighting fixture information search unit 12, the display data generation unit 13, the display control unit 14, the lighting fixture selection unit 15, and the model generation unit 16 may be configured by a processor such as a CPU (Central Processing Unit) or an FPGA (Field Programmable Gate Array), and may operate according to a program stored in a memory (not shown) to control each unit, or may realize some or all of its functions by hardware electronic circuits.

[0018] The information management unit 11 reads out and manages the information stored in the property information database 20 and the lighting fixture information database 30.

[0019] The property information database 20 stores property information. The property information includes information about a facility or space (hereinafter referred to as a design space (or target facility)) where lighting fixtures for which a lighting model is to be created will be installed, such as its purpose, size, height, facility specifications, and facility drawings. The property information includes at least 3D modeling data about the facility, and may include, for example, a request for a design proposal, the facility concept (including abstract information such as the impression of the space), a delivery date, a budget, the purpose, size, and height of the space, an address, facility specifications, and facility drawings. That is, the property information may include information about a lighting design request from a client, information about the target facility for which the lighting design is to be performed, and information about the client's requests regarding the lighting for the target facility. The request information may also include a request for an estimate of the cost of installing lighting for the target facility. The information about the target facility includes any of the dimensions of the target facility, including the size and height of the target facility, the address of the target facility, the target facility specifications, the target facility drawings, and the purpose of the target facility. The target facility drawings may be, for example, a spatial drawing of the target facility obtained using a 3D scanner or the like. Examples of the information indicating the purpose of the target facility include information indicating whether the target facility is outdoors or indoors, etc. Furthermore, the information indicating the purpose of the target facility may be information indicating that the target facility is an elevator hall, information indicating that the target facility is an outdoor stadium, etc.

[0020] The property information may also include requests regarding lighting fixtures to be used in the target facility, which is information regarding the client's requests regarding lighting for the target facility. Requests regarding lighting fixtures include the client's requests regarding the light intensity, luminous flux, light color, position, number of units, irradiation direction, irradiation position, etc. of the lighting fixtures. Requests regarding lighting fixtures may also include the client's requests regarding the model number, manufacturer, power consumption, price, etc. of the lighting fixtures to be used. Information regarding the client's requests regarding lighting for the target facility may also include the client's requests regarding the budget, delivery date, etc.

[0021] The information regarding the client's requests regarding the lighting of the target facility includes the client's concept regarding the lighting of the target facility. The client's concept may include abstract information such as requests regarding the spatial atmosphere to be realized by lighting in the target facility. Note that if existing lighting fixtures are used in the target facility, the client's requests regarding the spatial atmosphere may be expressed in comparison with the spatial atmosphere realized by the existing lighting fixtures. In this case, the request information may include images or the like showing the spatial atmosphere realized by the existing lighting fixtures.

[0022] Furthermore, information about various lighting fixtures is stored in the lighting fixture information database 30. For example, the lighting fixture information is information about the specifications of the lighting fixture, such as type, illuminance distribution, luminance distribution, evaluation results specific to the lighting environment (such as spatial brightness, glare, color appearance, visibility, and the influence of biological rhythms), energy consumption, three-dimensional shape, size, installation method, material, etc.

[0023] Furthermore, the information on lighting fixtures may include a list of fixtures that can be used for lighting in the target facility. The information on available lighting fixtures may include, for example, catalog information, 3D modeling data, etc., for available lighting fixtures. The catalog information, etc., on available fixtures may include, for each available fixture, the model, model number, light intensity, luminous flux, light color, power consumption, etc.

[0024] The information management unit 11 acquires property information from the property information database 20 and also acquires lighting fixture information from the lighting fixture information database 30. Note that although one property information database 20 and one lighting fixture information database 30 are shown in Fig. 1, there may be multiple property information databases 20 and multiple lighting fixture information databases 30. In this case, the information management unit 11 acquires property information and lighting fixture information from the multiple property information databases 20 and multiple lighting fixture information databases 30.

[0025] For example, the property information database 20 and the lighting fixture information database 30 may exist on the cloud. In this case, the information management unit 11 may use, for example, a web scraping technique to collect information from multiple websites that store property information and multiple websites that store lighting fixture information.

[0026] In this way, the information management unit 11 can acquire three-dimensional lighting fixture data such as BIM (Building Information Modeling) related data and electrical equipment CAD (Computer Aided Design) data provided by various companies as lighting fixture information.

[0027] The lighting fixture information search unit 12 searches for lighting fixtures suitable for a design space, which is a facility or space where lighting fixtures for which a lighting model is to be created will be installed. The lighting fixture information search unit 12 reads property information about the design space (hereinafter referred to as target property information) and also reads lighting fixture information. The lighting fixture information search unit 12 acquires various information about the design space where lighting fixtures will be installed from the target property information. Based on the acquired information, the lighting fixture information search unit 12 calculates specifications such as type, size, and illuminance of lighting fixtures suitable for the design space, and searches for lighting fixtures that satisfy these specifications based on the lighting fixture information. The lighting fixture information search unit 12 outputs information identifying one or more lighting fixtures as a search result to the lighting fixture selection unit 15.

[0028] The lighting fixture selection unit 15 reads information stored in the specification setting information storage unit 15a. The specification setting information storage unit 15a stores specification setting information that defines the lighting design concept to be set in the design space and various specification settings that provide a lighting environment-specific evaluation of the lighting fixtures to be installed in accordance with this concept, based on the information about the client's requests regarding the lighting of the target facility.

[0029] In detail, the specification setting information includes at least lighting design information using 3D modeling data related to the facility, such as past property information, lighting fixture information (catalog information, 3D modeling data), past design and proposal materials, 3D facility data, and measured 3D facility data. The information related to past lighting designs includes information about facilities for which lighting designs were performed in the past, design results of past lighting designs, analysis results of lighting for facilities for which lighting designs were performed in the past, and materials presented to clients for past lighting designs. The past lighting designs may be performed by a second user, such as a predetermined lighting manufacturer, or may be performed by a designer other than the second user.

[0030] The lighting fixture selection unit 15 selects a lighting fixture that satisfies the specifications based on the specification setting information stored in the specification setting information storage unit 15a from among one or more lighting fixtures indicated by the search results of the lighting fixture information search unit 12, and outputs the selection information to the information management unit 11.

[0031] Although the above description is of an example in which the lighting fixture selection unit 15 automatically selects lighting fixtures based on the specification setting information stored in the specification setting information storage unit 15a, this selection may also be made by a user. For example, the specification setting information storage unit 15a of the lighting fixture selection unit 15 may store multiple pieces of specification setting information permissible for lighting fixtures to be installed. In this case, the user may use an input device (not shown) to select desired specification setting information from the multiple pieces of specification setting information, and the lighting fixture selection unit 15 may select lighting fixtures corresponding to the selected specification setting information.

[0032] Alternatively, the user may select a lighting fixture by checking the display of one or more lighting fixtures as search results by the lighting fixture information search unit 12. That is, the lighting fixture information search unit 12 outputs lighting fixture information for one or more lighting fixtures as search results to the display data generation unit 13. The display data generation unit 13 generates display data based on the input lighting fixture information and outputs it to the display control unit 14. The display control unit 14 converts the input display data into a format compatible with the display device 40, and then outputs it to the display device 40. The display device 40 displays an image based on the display data on a display screen.

[0033] In this way, information about one or more lighting fixtures as a result of the search by the lighting fixture information search unit 12 is displayed on the display screen of the display device 40. The user selects a lighting fixture that is suitable for the specification setting while viewing this display.

[0034] In this case, the lighting fixture selection unit 15 may provide information about lighting fixtures that match the specification settings to the lighting fixture information search unit 12, and the lighting fixture information search unit 12 may output only those lighting fixtures that match the specification settings from the search results to the display data generation unit 13, and display information about those lighting fixtures on the display screen of the display device 40. In this case, the user can relatively easily select lighting fixtures that match the specification settings.

[0035] Furthermore, lighting fixture information from various companies is provided to the lighting fixture information search unit 12, and users such as facility personnel and lighting personnel can select lighting fixtures that match their lighting design from a wide range of options, rather than lighting fixtures from a specific company.

[0036] The information management unit 11 includes a superimposition processing unit 11a. The superimposition processing unit 11a receives selection information for identifying a lighting fixture from the lighting fixture selection unit 15. The superimposition processing unit 11a superimposes the lighting fixture information of the lighting fixture specified by the selection information on the target property information, thereby updating the property information.

[0037] The information management unit 11 outputs the updated target object information including the lighting fixture information to the lighting fixture selection unit 15. The lighting fixture selection unit 15 outputs the updated target object information to the model generation unit 16.

[0038] The model generation unit 16 generates information related to the lighting design based on the updated target property information. The information related to the lighting design includes, for example, the number and model of lighting fixtures, illuminance distribution, luminance distribution, evaluation results specific to the lighting environment (spatial brightness, glare, color appearance, visibility, influence of biological rhythms, etc.), energy consumption calculation sheet, estimate (including delivery date), etc. The model generation unit 16 provides the generated information related to the lighting design to the lighting design information storage unit 16a for storage.

[0039] Furthermore, the model generation unit 16 generates a 3D image model of the design space including the lighting fixtures based on the updated target property information. The model generation unit 16 provides information about the generated 3D image model to the display control unit 14. The display control unit 14 stores the information about the 3D image model in the lighting design information storage unit 16a and provides it to the display device 40 to display the 3D image model.

[0040] This 3D image model not only shows the shape of the design space and the shapes of the installed lighting fixtures in 3D, but also expresses the lighting conditions in the design space. Therefore, the user can easily understand not only the shapes of the lighting fixtures in the design space but also the brightness and color rendering properties from the display on the display screen of the display device 40.

[0041] Next, the operation of the embodiment configured as above will be described with reference to Fig. 2. Fig. 2 is a flowchart for explaining the operation of the embodiment.

[0042] The information management unit 11 acquires property information (S1) and lighting fixture information (S2). The lighting fixture information search unit 12 reads out target property information related to the design space from the information management unit 11, and also reads out lighting fixture information. The lighting fixture information search unit 12 searches for lighting fixtures suitable for the design space based on the target property information (S3). The information management unit 11 holds lighting fixture information related to lighting fixtures commercialized by multiple companies, and the lighting fixture information search unit 12 obtains one or more search results from among the many lighting fixtures from the multiple companies. The lighting fixture information search unit 12 outputs the search results to the lighting fixture selection unit 15. The lighting fixture information search unit 12 may also provide the search results to the display data generation unit 13, which may display information about the lighting fixtures in the search results on the display screen of the display device 40.

[0043] The lighting fixture selection unit 15 automatically or in response to a user's input operation selects lighting fixtures from the search results that satisfy the specification settings based on the specification setting information stored in the specification setting information storage unit 15a (S4), and outputs the selection information to the information management unit 11.

[0044] The superimposition processing unit 11a superimposes the lighting fixture information of the lighting fixtures specified by the selection information onto the target property information, thereby updating the property information (S5). The updated property information is supplied to the model generation unit 16 via the lighting fixture selection unit 15. The model generation unit 16 generates information related to the lighting design based on the updated property information, and generates a 3D image model of the design space including the lighting fixtures as part of that information (S6). The model generation unit 16 stores the generated lighting design information in the lighting design information storage unit 16a, and provides the 3D image model to the display device 40 via the display control unit 14 to display it on the display screen.

[0045] In this way, a 3D image model of a lighting fixture selected from many lighting fixtures in accordance with the specification settings and placed in the design space is displayed on the display screen of the display device 40. By looking at this display, the user can easily gain visual insight into lighting design.

[0046] As described above, in this embodiment, lighting design can be easily performed using property information and lighting fixture information related to lighting fixtures from multiple companies. Using lighting fixture information related to lighting fixtures from multiple companies significantly increases design flexibility. Furthermore, a 3D image model of the design space including lighting fixtures can be generated and output for display as information related to the generated lighting design, providing users with extremely easy-to-understand lighting design materials. Furthermore, users other than lighting specialists, such as facility managers, can also perform lighting design themselves. Therefore, facility managers, facility owners, developers, general contractors, subcontractors, agencies, and other personnel can more quickly obtain visually understandable lighting space design results.

For example, the commands and specification setting information from the terminal device 50 can be sent to the cloud 60 using a web browser or the like running on the terminal device 50. The commands and specification setting information from the terminal device 50 are received by the interface unit 18 of the lighting model processing device 10A. The specification setting information is stored in the specification setting information storage unit 15a of the lighting model processing device 10A. The lighting fixture information search unit 12, lighting fixture selection unit 15, and model generation unit 16 operate according to instructions from the terminal device 50 to search for lighting fixtures, select lighting fixtures, and generate lighting design information.

[0051] The display data from the display data generation unit 13 is provided to the terminal device 50 from the data output unit 17 and the interface unit 18 via the cloud 60, and is displayed on the display screen of the terminal device 50. The three-dimensional image model from the model generation unit 16 is also provided to the terminal device 50 from the data output unit 17 and the interface unit 18 via the cloud 60. In this way, the three-dimensional image model is displayed on the display screen of the terminal device 50.

[0052] In this way, in this embodiment, the same effects as in the first embodiment can be obtained, and easy-to-understand materials for designing and proposing lighting spaces can be easily provided using a terminal device such as a PC that can connect to the cloud.
