In addition, an information management unit 90 is mounted on the power supply board 81.

FIG. 2 is a diagram illustrating the part information of the lighting device 1 of the embodiment.

As shown in FIG. 1A and FIG. 2, the information management unit 90 has a memory element for storing information of various parts. The information management unit 90 is, for example, an IC (Integrated Circuit) tag (also referred to as an RF (Radio Frequency, radio frequency) tag or electronic tag). The information management unit 90 includes at least one component among the above-mentioned plural components. The part information includes information indicating the date and time of manufacturing the part, information indicating the factory where the part was manufactured, and information indicating the batch number, that is, information that can trace the production process. Also, at least the lot number can be included in the part information. The part information may also include information indicating the part number, information indicating the part name, etc. In addition, the information management section 90 also stores information indicating the part number of each part corresponding to each part information, information indicating the material constituting the part, and the like. The part number is an example of a specific part number.

As shown in Figure 2, the part information contains, for example, manufacturing time "20XX year XX month XX day XX hour XX minute", manufacturing plant "A factory" and batch number corresponding to the part number "H0001" of the part name "apparatus body". "R0001". In this embodiment, the information management unit 90 stores the part information table shown in FIG. 2, but it may also store a pattern that expresses the part information in a two-dimensional bar code.

Moreover, in the above, for example, the light-emitting module 50, the power supply box 80, etc. are set as one of a plurality of parts, and the light-emitting module 50, the power supply box 80, etc. further include a plurality of parts. Therefore, the information management unit 90 also stores information indicating a plurality of parts constituting the light-emitting module 50, the power supply box 80, and the like. Taking the power supply box 80 as an example for specific description, the information management unit 90 stores the parts in units of a group consisting of a plurality of parts constituting the power supply box 80, namely, resistors, capacitors, power substrate 81, and metal casing 83. Information.

In addition, the information management unit 90 is housed in the metal casing 83 and held on the surface of the power supply board 81 (the surface on the side of the building material). In addition, the information management unit 90 only needs to be capable of wireless communication with the communication terminal 3, and it is not an essential requirement to be held on the power supply board 81. It can be arranged on the outer side surface of the metal casing 83 of the power box 80, and can also be arranged on other parts. The metal shell 83 is included in at least one of the above-mentioned plural parts.

3 is a front view illustrating the through hole 83a formed in the metal casing 83 of the lighting device 1 of the embodiment. As shown in FIG. 3, a through hole 83a is formed in the metal casing 83, and the through hole is used for the passage of radio waves for wireless communication between the information management unit 90 and the communication terminal 3. The through hole 83 a is formed at a position opposite to the information management unit 90 housed in the metal casing 83. In other words, when the through hole 83a and the information management part 90 are viewed from the front, the through hole 83a is formed at a position overlapping the information management part 90. The communication terminal 3 is, for example, a dedicated terminal, a smart phone, etc. that can read parts information from the information management unit 90.

The above-mentioned plural parts are provided with media 5 that encodes part information. More specifically, the medium 5 is attached or printed on each part. This medium 5 is a two-dimensional bar code.

[action] Next, a method of manufacturing the lighting device 1 will be described.

FIG. 4 is a flowchart illustrating the manufacturing method of the lighting device 1 of the embodiment.

As shown in FIG. 4, first, the worker prepares (for example, manufactures) the parts constituting the lighting device 1 for assembling the lighting device 1 (S11). For example, an operator manufactures the instrument body 10, the lampshade portion 20, the frame body 30, a plurality of leaf springs 40, the light-emitting module 50, the reflective member 60, the optical member 70, the power supply box 80, and the like. In addition, for the light-emitting module 50, the power supply box 80, and the like, the operator manufactures a plurality of parts constituting them. Assign a part number to each of these parts.

Next, the information indicating the part number of each part is stored in the information management section 90 (S12). When assembling the lighting device 1, in order to prevent the confusion of parts with different part numbers, in other words, to prevent incorrect assembly, information indicating the part numbers of each part is stored in the information management unit 90.

Next, the operator assigns a medium 5 for encoding the part information to each part (S13). Specifically, the medium 5 is attached or printed on each part. For example, three-dimensional printers are used to print parts. The part information includes: information indicating the name of the part, information indicating the date and time of manufacturing the part, information indicating the factory where the part was manufactured, and information indicating the batch number, etc. In addition, the part information corresponds to the information indicating the part number.

Furthermore, when the operator assigns the medium 5 to each part, he can also pay attention to the assigned position. Taking the leaf spring 40 as an example for description, when the lighting device 1 is mounted on a building material, the leaf spring 40 may rub against the mounting hole of the building material. Therefore, as shown in FIG. 1B, the operator can also apply the medium 5 to the position where the leaf spring 40 does not contact the mounting hole of the building material, that is, the surface of the leaf spring 40 on the appliance body 10 side (the surface opposite to the building material side) Of the face).

Furthermore, in the power supply board 81 of the power supply box 80 of the configuration information management unit 90, the medium 5 for encoding the part information of the power supply board 81 can also be omitted. The reason is that the part information of the power substrate 81 is stored in the information management unit 90, so the medium 5 for encoding the part information of the power substrate 81 can be omitted. That is, it is not limited to the power supply board 81, and when the information management unit 90 is arranged in other parts, the medium 5 for encoding the part information of the arranged parts may be omitted.

In addition, when the operator assembles each part, the part information of each part is stored in the information management section 90 (S14). For example, the operator uses a dedicated reading device to read the medium 5 assigned to each part, thereby storing the part information of each part in the information management unit 90.

Furthermore, it is not limited to the order of this embodiment, and step S14 may be performed after step S13 is performed. That is, it is sufficient to perform step S13 and step S14 during the period from the manufacture of the part to the assembly. Moreover, step S12 and step S14 may be performed simultaneously. Therefore, step S12 and step S14 may not be performed in different steps. Furthermore, after performing step S13 and step S14 for each part, it may proceed to step S15, or after performing step S13 for all parts, step S14 may be performed for all parts.

Next, the worker starts the assembling operation using the plural parts given to the medium 5 (S15). Thus, the lighting device 1 is manufactured.

[Confirm whether there are specific parts to be recalled] After the manufactured lighting device 1 is embedded in the building material, the operator can perform wireless communication with the information management unit 90 of the lighting device 1 by operating the communication terminal 3. When the radio wave is received from the communication terminal 3, the information management unit 90 transmits parts information to the communication terminal 3. When the communication terminal 3 receives the parts information from the information management part 90, the part information is displayed on the display part of the communication terminal 3. Therefore, the worker can easily check whether the lighting device 1 is equipped with the specific parts subject to the recall.

[Effect] Next, the effects of the lighting device 1 and the method of manufacturing the lighting device 1 in this embodiment will be described.

As described above, the lighting device 1 of the present embodiment is an embedded type and includes a plurality of parts. In addition, the plural parts include the information management unit 90. In addition, part information related to each part is stored in the information management unit 90.

Previously, for example, when specific parts constituting a lighting device are subject to recall, in order to confirm whether the recalled parts are included, it is necessary to remove the embedded lighting device from the building materials that contains the recalled parts. In addition, even if the lighting device and the recalled product are the same product, it may not be possible to determine whether or not the recalled parts are installed without disassembling the lighting device. Therefore, even if the product is not originally the object of the recall, if there is a possibility that the component that is the object of the recall may be installed, it is necessary to disassemble the lighting device after removal, and there is a concern that the workload will increase.

Therefore, according to the lighting device 1, the part information of each part constituting the lighting device 1 is stored in the information management unit 90. Therefore, the lighting device 1 can easily trace back various parts. As a result, the worker does not need to disassemble the lighting device 1, and can easily check whether the lighting device 1 is equipped with a specific part to be recalled, and therefore, it is possible to suppress an increase in workload.

In addition, the manufacturing method of the lighting device 1 of the present embodiment is the manufacturing method of the embedded lighting device 1, and includes: storing the part numbers of a plurality of parts to be assembled in the information management section 90; and storing information related to each part The part information is attached or printed on each part; and when assembling each part, the part information corresponding to the part number of each part is stored in the information management section 90.

The manufacturing method of the lighting device 1 also plays the same role as described above.

In addition, in the manufacturing method of the lighting device 1, by storing the part numbers of a plurality of parts to be assembled in the information management section 90, it is possible to suppress incorrect assembly.

In addition, in the lighting device 1 of this embodiment, a medium 5 for encoding the part information is attached or printed on each part.

Thereby, the coded medium 5 can be easily provided to each part.

In addition, in the lighting device 1 of this embodiment, the medium 5 is a two-dimensional barcode.

In this way, coded part information can be assigned to each part.

Furthermore, in the lighting device 1 of this embodiment, the information management unit 90 is an IC tag. In addition, the plurality of parts includes a metal casing 83 that houses the information management unit 90. In addition, a through hole 83 a is formed in the metal case 83, and the through hole 83 a is used for the passage of radio waves for wireless communication between the information management unit 90 and the communication terminal 3.

Thereby, the information management unit 90 mounted on the metal casing 83 and the communication terminal 3 can communicate reliably.

Furthermore, in the lighting device 1 of this embodiment, the through hole 83a is formed at a position facing the information management unit 90.

Thereby, the information management unit 90 mounted on the metal casing 83 and the communication terminal 3 can communicate more reliably.

In addition, in the lighting device 1 of this embodiment, the part information includes information indicating the date and time of manufacturing the part, information indicating the factory where the part was manufactured, and information indicating the lot number.

Thereby, if the part information can be read from the information management unit 90, the operator can know in detail the information related to the parts constituting the lighting device 1, so it can be specified whether the lighting device 1 is equipped with the recalled parts. Therefore, if the parts subject to the recall are included, the operator only needs to replace the parts subject to the recall on the spot, and it is no longer necessary to collect and investigate the lighting device 1 itself. Therefore, the corresponding burden on the operator can be reduced.
