Description

Embodiments of the present invention relate to an illumination model processing device, an illumination model processing method, and an illumination model processing system.

Traditionally, architectural design has sometimes been carried out using three-dimensional information about buildings and other structures (hereinafter referred to as property information). Using this property information makes it possible to centrally manage information related to planning, design, construction, and maintenance. This property information can also be used for lighting design. Lighting designers use information about various lighting fixtures and other fixtures in conjunction with the property information to create lighting designs that are appropriate for the design space.

Such lighting designs are carried out by designated personnel, and the results of the lighting designs are provided to the various personnel in charge of the facility, including facility managers, facility owners, developers, general contractors, subcontractors, and agencies.

As a result, the time required to obtain lighting design results is highly dependent on the lighting designer, and there is the issue that it can take an extremely long time for the lighting design results to be provided to each of these designers.

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

(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.

In FIG. 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 FPGA (Field Programmable Gate Array), and may operate according to a program stored in memory (not shown) to control each unit, or may realize some or all of its functions using hardware electronic circuits.

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

The property information database 20 stores property information. The property information includes information about the facility or space (hereinafter referred to as the design space (or target facility)) where the lighting fixtures for which the 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), delivery date, budget, the purpose, size, and height of the space, address, facility specifications, and facility drawings. In other words, 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 a cost estimate for the installation of lighting for the target facility. 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, 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 information indicating the purpose of the target facility include information indicating whether the target facility is indoors or outdoors. Information indicating the purpose of the target facility may also be information indicating that the target facility is an elevator hall, or information indicating that the target facility is an outdoor stadium, etc.

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, illumination direction, illumination 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 budget, delivery date, etc.

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, requests regarding the spatial atmosphere may be indicated by comparing it with the spatial atmosphere realized by the existing lighting fixtures. In this case, images or the like showing the spatial atmosphere realized by the existing lighting fixtures may be included in the request information.

The lighting fixture information database 30 also stores information about various lighting fixtures. For example, lighting fixture information includes information about lighting fixture specifications, such as type, illuminance distribution, luminance distribution, evaluation results specific to the lighting environment (spatial brightness, glare, color appearance, visibility, effects of biological rhythms, etc.), energy consumption, three-dimensional shape, size, installation method, material, etc.

Information about lighting fixtures may also include a list of fixtures that can be used to light the target facility. Information about available lighting fixtures may include, for example, catalog information, 3D modeling data, etc., for available lighting fixtures. Catalog information about available fixtures may include the model, model number, light intensity, luminous flux, light color, and power consumption for each available fixture.

The information management unit 11 acquires property information from the property information database 20 and lighting fixture information from the lighting fixture information database 30. Note that while Figure 1 shows one property information database 20 and one lighting fixture information database 30, 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.

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

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.

The lighting fixture information search unit 12 searches for lighting fixtures suitable for the design space, which is the facility or space in which the lighting fixtures for which a lighting model is to be created will be installed. The lighting fixture information search unit 12 reads property information related to 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 related to the design space in which the 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 the 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 the search results to the lighting fixture selection unit 15.

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 information about the client's requests regarding the lighting of the target facility described above.

In detail, the specification setting information includes lighting design information using at least 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. Information related to past lighting designs includes information about facilities for which lighting designs have been performed in the past, the design results of past lighting designs, the analysis results of lighting for facilities for which lighting designs have been performed in the past, and materials presented to clients for past lighting designs. The past lighting designs may have been performed by a second user, such as a specified lighting manufacturer, or by a designer other than the second user.

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

In the above example, 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. However, this selection may also be made by the 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 that are acceptable for the lighting fixture to be installed. In this case, the user can use an input device (not shown) to select the desired specification setting information from the multiple pieces of specification setting information, and the lighting fixture selection unit 15 can select the lighting fixture that corresponds to the selected specification setting information.

The user may also be configured to select a lighting fixture by checking the display of one or more lighting fixtures that are 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 that are 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 its display screen.

In this way, information about one or more lighting fixtures based on the search results of the lighting fixture information search unit 12 is displayed on the display screen of the display device 40. The user can view this display and select lighting fixtures that are suitable for the specification settings.

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, causing information about those lighting fixtures to be displayed 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.

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

The information management unit 11 includes a superimposition processing unit 11a. The superimposition processing unit 11a receives selection information 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 onto the target property information, thereby updating the property information.

The information management unit 11 outputs the updated target property information, including the lighting fixture information, to the lighting fixture selection unit 15. The lighting fixture selection unit 15 outputs the updated target property information to the model generation unit 16.

The model generation unit 16 generates information related to the lighting design based on the updated target property information. 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, effects of biological rhythms, etc.), energy consumption calculation sheets, estimates (including delivery dates), 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.

The model generation unit 16 also generates a three-dimensional 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 three-dimensional image model to the display control unit 14. The display control unit 14 stores the information about the three-dimensional image model in the lighting design information storage unit 16a and provides it to the display device 40 to display the three-dimensional image model.

This three-dimensional image model not only represents the shape of the design space and the shape of the installed lighting fixtures in three dimensions, but also expresses the lighting conditions in the design space. Therefore, the user can easily understand not only the shape of the lighting fixtures in the design space, but also the impression of brightness, color rendering, etc., from the display on the display screen of the display device 40.

Next, the operation of the embodiment configured in this manner will be described with reference to Figure 2. Figure 2 is a flowchart illustrating the operation of the embodiment.

The information management unit 11 acquires property information (S1) and lighting fixture information (S2). The lighting fixture information search unit 12 reads target property information related to the design space from the information management unit 11, and also reads 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 stores 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 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.

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.

The superimposition processing unit 11a superimposes the lighting fixture information of the lighting fixtures specified by the selection information onto the target property information, 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 that includes 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.

In this way, the display screen of the display device 40 displays a three-dimensional image model of the lighting fixture selected from a large number of lighting fixtures in accordance with the specification settings, as it would appear when placed in the design space. By viewing this display, the user can easily gain visual insight into the lighting design.

In this way, in this embodiment, lighting design can be easily carried out 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 the degree of freedom in design. 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 design lighting themselves. Therefore, facility managers, facility owners, developers, general contractors, subcontractors, agencies, and other personnel can more quickly obtain visually understandable lighting space design results.
