[0011] Hereinafter, light source units and lighting fixtures according to embodiments will be described with reference to the drawings. The drawings referred to in the following embodiments are schematic diagrams, and the sizes and thicknesses of the components in the drawings do not necessarily reflect the actual dimensions, and the size and thickness ratios between the components do not necessarily reflect the actual dimensional ratios.

[0012] (Embodiment) (1) Overview First, an overview of a light source unit B1 and a lighting device A1 according to the embodiment will be described with reference to FIGS.

[0013] As shown in Fig. 1, the lighting fixture A1 according to this embodiment includes a light source unit B1 and a fixture body 6. The fixture body 6 supports the light source unit B1. The light source unit B1 is detachably attached to the fixture body 6, which is directly attached to a ceiling, for example. However, the fixture body 6 may also be embedded in the ceiling, directly attached to a wall, or embedded in the wall.

[0014] The light source unit B1 according to the embodiment includes a light source module 1, a power supply device 2, an attachment member 3, a cover 5, and a confirmation unit 7. The light source module 1 has a plurality of light-emitting elements 10 and a substrate 11 on which the plurality of light-emitting elements 10 are mounted. The power supply device 2 supplies lighting power to the plurality of light-emitting elements 10. The attachment member 3 has a first surface 301 (see FIG. 3) and a second surface 302 (see FIG. 3) opposite to the first surface 301. The substrate 11 is attached to the first surface 301, and the power supply device 2 is attached to the second surface 302. The cover 5 is translucent and is attached to the attachment member 3 so as to cover the substrate 11. The confirmation unit 7 can confirm that at least one of the light source module 1, the power supply device 2, and the cover 5 has been replaced.

[0015] The light source unit B1 according to the embodiment includes a confirmation unit 7 that can confirm that at least one of the light source module 1, the power supply device 2, and the cover 5 has been replaced. Therefore, it is possible to confirm that at least one of the light source module 1, the power supply device 2, and the cover 5 has been replaced simply by checking the confirmation unit 7. In other words, the light source unit B1 according to the embodiment makes it possible to easily confirm whether or not a part has been replaced.

[0016] (2)Details Next, each component of the lighting device A1 and the light source unit B1 according to this embodiment will be described with reference to FIGS.

[0017] In the following description, unless otherwise specified, the front-to-back, left-to-right, and up-to-down directions (vertical directions) indicated by arrows in Figures 1 to 3 are defined as the front-to-back, left-to-right, and up-to-down directions of the lighting fixture A1, light source unit B1, and their components, respectively. However, these directions are not intended to limit the directions of the lighting fixture A1, light source unit B1, and their components when in use. Furthermore, the arrows indicating "up," "down," "left," "right," "front," and "back" in Figures 1 to 3 are merely shown for the purpose of explanation and do not have any physical substance.

[0018] 1, the lighting fixture A1 according to this embodiment includes a light source unit B1 and a fixture body 6. The fixture body 6 supports the light source unit B1.

[0019] (2.1) Device body As shown in Fig. 1, the fixture body 6 has a storage section 60, a pair of reflecting plates 61, and a pair of end plates 62. The storage section 60 is formed in the shape of a rectangular box with an open bottom. The pair of reflecting plates 61 protrude obliquely upward from the opening edge on both sides along the longitudinal direction (left-right direction) of the storage section 60. The pair of end plates 62 are provided at both ends of the storage section 60 and the pair of reflecting plates 61 in the longitudinal direction.

[0020] The fixture main body 6 is installed on the ceiling by inserting suspension bolts (not shown) into at least two of a plurality of mounting holes 63 provided on the bottom surface of the housing portion 60 and tightening nuts (not shown) onto the suspension bolts. A power line is inserted into one of a plurality of power supply holes 64 provided on the bottom surface of the housing portion 60. The power line inserted into the power supply hole 64 is electrically connected to a terminal block 65 attached to the bottom surface of the housing portion 60. Three electric wires 66, each electrically connected to a male power connector 67 at its tip, are connected to the terminal block 65.

[0021] (2.2) Light source unit As shown in FIG. 1, the light source unit B1 includes a light source module 1, a power supply device 2, an attachment member 3, a cover 5, and a confirmation portion .

[0022] (2.2.1) Light source module The light source module 1 has a plurality of light-emitting elements 10 and a substrate 11. Each of the plurality of light-emitting elements 10 is, for example, an LED (Light Emitting Diode). More specifically, each light-emitting element 10 is, for example, a packaged white LED for illumination. Note that each light-emitting element 10 is not limited to an LED, and may be, for example, an organic electroluminescence element or a semiconductor laser element.

[0023] The substrate 11 is formed in a long rectangular shape. However, the substrate 11 may be configured by connecting multiple substrates in the longitudinal direction. The multiple light-emitting elements 10 are mounted in a single row at equal intervals along the longitudinal direction (left-right direction) of the substrate 11, at the center of the short side direction (front-rear direction) on the surface (lower surface) of the substrate 11. The multiple light-emitting elements 10 are electrically connected in series or series-parallel by printed wiring formed on the surface of the substrate 11. As described above, in the light source unit B1 according to the embodiment, the light source module 1 has the multiple light-emitting elements 10 and the substrate 11 on which the multiple light-emitting elements 10 are mounted.

[0024] (2.2.2) Power supply The power supply device 2 supplies lighting power to the plurality of light-emitting elements 10. As shown in Fig. 1, the power supply device 2 has a lighting circuit 20 and a power supply case 21 that houses the lighting circuit 20. The lighting circuit 20 is composed of a printed circuit on which various electronic components including integrated circuits and a female power connector 23 are mounted on a rectangular printed circuit board 22. The power connector 23 is electrically and mechanically connected to the power connector 67.

[0025] The power supply case 21 is made of a metal plate and is formed into a long rectangular box shape with one surface (bottom surface) open. The power supply case 21 houses the lighting circuit 20 and is fixed to the mounting member 3 via a pair of second holding claws 33 (described later) with the open surface facing the second surface 302 (see FIG. 3) of the main body 30 of the mounting member 3.

[0026] The power supply case 21 is electrically connected to the mounting member 3 when it is fixed to the mounting member 3. Furthermore, the mounting member 3 is electrically connected to the fixture body 6 when the light source unit B1 is attached to the fixture body 6. Therefore, the power supply case 21 of the power supply device 2 is electrically connected to the fixture body 6 via the mounting member 3.

[0027] The lighting circuit 20 is supplied with AC power from a commercial power system via a power connector 23. The lighting circuit 20 has a power conversion circuit, a constant current circuit, and a control circuit.

[0028] The power conversion circuit is configured to convert AC power supplied from a power grid into DC power, and includes, for example, a full-wave rectifier circuit, a power factor correction circuit (a step-up chopper circuit), and a buck converter (a step-down chopper circuit).

[0029] The constant current circuit is configured to make the DC current supplied from the power conversion circuit to the light source module 1 coincide with a target value.

[0030] The control circuit, which mainly includes a microcontroller, is configured to switch between operating and stopping the power conversion circuit and the constant current circuit, and to change the target value of the DC current (load current) in the constant current circuit.

[0031] (2.2.3) Mounting parts The mounting member 3 is formed, for example, from a metal plate in a long rectangular shape. As shown in Fig. 3, the mounting member 3 has a main body 30, a pair of hooking grooves 31, a pair of first holding claws 32, and a pair of second holding claws 33.

[0032] The main body 30 is formed in the shape of a long plate extending in the left-right direction. The main body 30 has a first surface 301 and a second surface 302. The first surface 301 and the second surface 302 face each other in the thickness direction (up-down direction) of the main body 30. That is, the mounting member 3 has the first surface 301 and the second surface 302 opposite to the first surface 301.

[0033] The pair of hooking grooves 31 are provided at both ends in the short-side direction (front-rear direction) of the main body 30. Each of the pair of hooking grooves 31 is formed in a U-shape or an inverted U-shape when viewed from above in the longitudinal direction (left-right direction) of the mounting member 3. Each hooking groove 31 is formed over the entire length of the mounting member 3. The cover 5 is attached to the mounting member 3 by hooking a pair of hooking portions 51 of the cover 5, which will be described later, into the pair of hooking grooves 31 (see FIG. 3).

[0034] The pair of first holding claws 32 are provided on the first surface (lower surface) 301 of the main body 30. Each of the pair of first holding claws 32 has a first piece 321 that protrudes downward from the first surface 301 of the main body 30, and a second piece 322 that protrudes inward from the tip of the first piece 321 so as to approach each other. Each first holding claw 32 is formed in an L-shape or an inverted L-shape when viewed from a plane in the longitudinal direction (left-right direction) of the main body 30. Furthermore, each first holding claw 32 is formed, for example, over the entire length of the main body 30.

[0035] The light source module 1 is attached to the main body 30 by sliding it in one direction (left and right direction) relative to the main body 30 of the mounting member 3. At this time, the light source module 1 is housed in a space S1 surrounded by the first surface 301 of the main body 30 and the pair of first holding claws 32. Note that although there is a gap between the substrate 11 of the light source module 1 and each of the first holding claws 32 in FIG. 3, in reality, the substrate 11 and each of the first holding claws 32 are in contact with each other.

[0036] The pair of second holding claws 33 are provided on the second surface (upper surface) 302 of the main body 30. Each of the pair of second holding claws 33 has a first piece 331 protruding upward from the second surface 302 of the main body 30, and a second piece 332 protruding inward from the tip of the first piece 331 so as to approach each other. Each second holding claw 33 is formed in an L-shape or an inverted L-shape when viewed from a plane in the longitudinal direction (left-right direction) of the main body 30. Furthermore, each second holding claw 33 is formed, for example, over the entire length of the main body 30.

[0037] The power supply device 2 is attached to the main body 30 by sliding it in one direction (left and right direction) relative to the main body 30 of the mounting member 3. At this time, the power supply device 2 is housed in a space S2 surrounded by the second surface 302 of the main body 30 and the pair of second holding claws 33. Note that although there is a gap between the power supply case 21 of the power supply device 2 and each of the second holding claws 33 in FIG. 3, in reality, the power supply case 21 and each of the second holding claws 33 are in contact with each other.

[0038] As described above, in the light source unit B1 according to this embodiment, the substrate 11 is attached to the first surface 301 of the attachment member 3, and the power supply device 2 is attached to the second surface 302 of the attachment member 3.

[0039] (2.2.4) Cover As shown in Fig. 3, the cover 5 has a cover body 50 and a pair of hook portions 51. The cover body 50 is formed in a long semi-cylindrical shape. The pair of hook portions 51 protrude inward along the longitudinal direction (left-right direction) of the cover body 50 from both ends in the short side direction (front-rear direction) of the cover body 50. The cover body 50 and the pair of hook portions 51 are integrally formed from a translucent synthetic resin such as acrylic resin or polycarbonate resin.

[0040] The cover 5 is attached to the mounting member 3 by sliding it in one direction (left-right direction) relative to the main body 30 of the mounting member 3. At this time, each of the pair of hooking portions 51 of the cover 5 is hooked into a corresponding one of the pair of hooking grooves 31 of the mounting member 3 (see FIG. 3). Then, the cover 5 covers the substrate 11 when attached to the mounting member 3 (see FIG. 3). That is, in the light source unit B1 according to this embodiment, the cover 5 is translucent and is attached to the mounting member 3 so as to cover the substrate 11.

[0041] (2.2.5) Confirmation section The confirmation unit 7 can confirm that at least one of the light source module 1, the power supply device 2, and the cover 5 has been replaced. Here, as described above, the light source module 1 has a plurality of light-emitting elements 10, and has a shorter product life than the power supply device 2 and the cover 5. Therefore, it is expected that the light source module 1 will be replaced most frequently. As an example, in this embodiment, as shown in FIGS. 1 and 2, the confirmation unit 7 can confirm that the light source module 1 has been replaced.

[0042] The confirmation unit 7 includes a security seal (an anti-tamper seal, a prohibition seal, an tamper-evident seal, a seal, or a tamper-evident seal) attached to the mounting member 3 or the cover 5. In the present embodiment, as an example, the confirmation unit 7 is attached to the mounting member 3 as shown in FIG. 2 . As described above, the substrate 11 of the light source module 1 is attached to the first surface 301 of the main body 30 of the mounting member 3. When the substrate 11 is removed from the mounting member 3, a portion of the security seal remains attached to the first surface 301 of the main body 30 of the mounting member 3. Therefore, an operator can confirm that the light source module 1 has been replaced by checking the portion of the security seal attached to the first surface 301 of the main body 30 of the mounting member 3. In the present embodiment, the security seal corresponds to a first security seal indicating that the light source module 1 has been removed from the mounting member 3. That is, the security seal includes a first security seal indicating that the light source module 1 has been removed from the mounting member 3.

[0043] Here, if the light source module 1 has been replaced multiple times, multiple security stickers will be affixed to the first surface 301 of the main body 30 of the mounting member 3. Therefore, it is possible to know the number of times the light source module 1 has been replaced from the number of security stickers affixed to the first surface 301 of the main body 30.

[0044] (3) Effects The light source unit B1 according to the embodiment includes a confirmation unit 7. In the present embodiment, the confirmation unit 7 includes a security seal (first security seal) that indicates that the light source module 1 (substrate 11) has been removed from the mounting member 3. Therefore, it is possible to confirm that the light source module 1 has been removed from the mounting member 3 simply by checking a portion of the security seal that remains on the mounting member 3. In other words, the light source unit B1 according to the embodiment makes it possible to easily confirm whether or not a part (in the present embodiment, the light source module 1) has been replaced.

[0045] (4) Variations The above-described embodiment is merely one of various embodiments of the present disclosure. The above-described embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved.

[0048] The mounting member 3 has a main body 30, a pair of first retaining claws 32, a pair of second retaining claws 33, and a pair of hooking claws 34. Each of the pair of hooking claws 34 has a first piece 341 that protrudes upward from the second surface 302 of the main body 30, and a second piece 342 that protrudes in directions away from each other (outward) from the tip of the first piece 341. Each of the hooking claws 34 is formed in an L-shape or an inverted L-shape when viewed in a plan view from the longitudinal direction (left-right direction) of the main body 30. Furthermore, each of the hooking claws 34 is formed, for example, over the entire length of the main body 30.

[0049] As shown in Fig. 4, a pair of hooking claws 34 are formed on the second surface 302 of the main body 30, thereby forming a pair of hooking grooves 35 between the main body 30 and the pair of hooking claws 34. The cover 5 is attached to the mounting member 3 by sliding the cover 5 in one direction (left-right direction) relative to the main body 30 of the mounting member 3. At this time, each of the pair of hooking portions 51 of the cover 5 is hooked into the corresponding one of the pair of hooking grooves 35 of the mounting member 3 (see Fig. 4).

[0050] In the light source module B1 according to the first modification, simply by checking the checking unit 7, it is possible to confirm that a part (for example, the light source module 1) has been replaced.
