Patent Document 1: Japanese Patent Application Publication No. 2015-115287

However, in this type of lighting device, the antenna pattern extends in a direction perpendicular to the substrate. Therefore, for example, in the case of assembling various parts to manufacture a lighting device, when transporting a member in a state where the antenna pattern and the substrate are integrated and assembled, the antenna pattern protrudes vertically with respect to the substrate. The line pattern may be damaged by contact with an object. Therefore, it is necessary to protect the antenna pattern with a protective member or the like so that the antenna pattern will not be damaged during transportation. Therefore, as a result, unnecessary costs are increased in the assembly of parts.

Therefore, the purpose of this disclosure is to provide a lighting device that can suppress the increase in manufacturing costs for assembling the lighting device.

In order to achieve the above object, an aspect of the lighting device of the present invention includes: a second substrate, which is supported in a state of being erected relative to the first substrate; and a mounting plate, which holds the first substrate and is freely detachable The second substrate is held in a manner; and the mounting board has: a receiving and supporting portion with a receiving space for inserting the second substrate; and the receiving and supporting portion has: an engaging recess that is engaged with the second substrate The second substrate is supported in a predetermined posture.

According to the disclosure of this case, the high manufacturing cost of assembling the lighting device can be suppressed.

〔Lighting Department〕

The illuminating unit 20 has a long rectangular shape in the Y-axis direction. That is, the longitudinal direction of the illuminating unit 20 becomes the Y-axis direction. The illuminating part 20 has a circular-shaped first opening 20a in the central part. The first opening 20a is an opening for installation, and the illuminating unit 20 is installed to the suspended ceiling 11 via the first opening 20a. Thereby, the illuminating part 20 is electrically connected to the suspended ceiling piece 11. In addition, the lighting unit 20 includes a pair of light-emitting modules 21; a housing 25; a first circuit board 260; a second circuit board 270 for the audio unit 40; and a third circuit board 280.

〔Light emitting module〕

As shown in FIG. 2, the pair of light-emitting modules 21 are fixed to the receiving body 25 by fastening members 19 such as screws. Specifically, the pair of light emitting modules 21 are respectively arranged on the Y-axis positive direction side and the Y-axis negative direction side with respect to the first opening 20a so as to sandwich the first opening 20a. In addition, in this embodiment, two light-emitting modules 21 are used, but one light-emitting module 21 may also be used.

FIG. 4 is a partial cross-sectional view of the illuminating device 1 when the cross section including the IV-IV line segment of FIG. 1 is observed.

As shown in FIGS. 2 and 4, the light-emitting module 21 has: a substrate 120; a plurality of first light sources 121; a plurality of second light sources 122; and a plurality of wiring members 120a.

The substrate 120 has a rectangular plate shape that is long in the Y-axis direction. A plurality of first light sources 121 and a plurality of second light sources 122 are mounted on the substrate 120. The substrate 120 is installed in the housing 25 of the illuminating unit 20 so as to be substantially parallel to the X-Y plane. The substrate 120 is fixed with a wiring member 120a, which supplies power to a plurality of first light sources 121 and a plurality of second light sources 122. The substrate 120 is electrically connected to the lighting control unit 13 and the lighting power supply unit 15 via a cable (not shown) connected to the wiring member 120a. In this embodiment, the wiring member 120a is arranged between the first light source 121 and the second light source 122.

The substrate 120 may also be thermally connected with a heat dissipating portion (not shown) to dissipate the heat emitted by the first light source 121 and the second light source 122. The heat sink may also be connected to the outer cover 12 thermally, and the outer cover 12 may function as a heat sink.

Most of the first light sources 121 are arranged on the substrate 120 in a matrix with the Y-axis direction as the length. A part of the plurality of second light sources 122 is arranged along the Y-axis direction on the X-axis positive direction side with respect to the plurality of first light sources 121. On the other hand, the other majority of the second light sources 122 are relative to the majority of the first light sources 121 They are arranged along the Y-axis direction on the negative side of the X-axis. In other words, with respect to the majority of first light sources 121, the majority of second light sources 122 arranged on the positive side of the X-axis and the majority of second light sources 122 aligned on the side of the negative X-axis to sandwich the majority of first The light sources 121 are arranged on the substrate 120 in a manner.

Since the light emission direction of the first light source 121 and the second light source 122 faces the negative direction of the Z axis, light is emitted in the negative direction of the Z axis in the past. The light emission direction, that is, the optical axis J of each of the first light source 121 and the second light source 122, is approximately parallel to the Z axis direction.

The first light guide plate 3 is arranged on the light emitting direction side of the plurality of second light sources 122 arranged on the positive direction side of the X-axis. In addition, the second light guide plate 4 is arranged on the light emission direction side of the plurality of second light sources 122 arranged on the negative direction side of the X-axis. The second light source 122 on the positive X-axis direction irradiates light to the incident surface of the first light guide plate 3. In addition, the second light source 122 on the negative X-axis direction irradiates light to the incident surface of the second light guide plate 4. The second light sources 122 are arranged on the substrate 120 in such a manner that the light emission direction faces the negative direction of the Z-axis. Specifically, the second light source 122 on the positive direction of the X-axis has an optical axis J that is substantially orthogonal to the incident surface of the first light guide plate 3 and is arranged to face the incident surface. In addition, the second light source 122 on the negative X-axis direction has an optical axis J substantially orthogonal to the incident surface of the second light guide plate 4 and is arranged to face the incident surface. That is, the second light source 122 is in a relationship substantially perpendicular to the incident surface of each of the first light guide plate 3 and the second light guide plate 4.

In addition, there is a gap between the second light source 122 and the first light guide plate 3 and the second light guide plate 4 so that the second light source 122 does not contact the first light guide plate 3 and the second light guide plate 4.

The first light source 121 and the second light source 122 are so-called SMD (Surface Mount Device) type LED elements. The SMD type LED element is specifically an LED chip (light-emitting element) mounted in a cavity formed by resin molding, and a encapsulated LED element containing phosphor resin is enclosed in the cavity. For example, as the first light source 121 and the second light source 122, a surface-mounted LED element that emits white light by a combination of a blue LED chip and a yellow light-containing phosphor resin is used.

The first light source 121 and the second light source 122 are controlled by the lighting control unit 13 to be turned on and off. In addition, the first light source 121 and the second light source 122 are controlled by the lighting control unit 13 to perform dimming and color adjustment.

In addition, the first light source 121 and the second light source 122 are not limited to this configuration, and a COB (Chip On Board) type module in which LED chips are directly mounted on the substrate 120 can also be used. In addition, the light-emitting elements included in the first light source 121 and the second light source 122 are not limited to LEDs, and may be semiconductor light-emitting elements such as semiconductor lasers, organic EL (Electro Luminescence), and inorganic EL. Components and other solid-state light-emitting components.

In addition, the light-emitting module 21 on the other side also has the same structure, so its description is omitted.

〔Lens cover〕

As shown in FIGS. 2 and 3, a pair of lens covers 23 are arranged on the Y-axis positive direction side and the Y-axis negative direction side with respect to the first opening 20a so as to sandwich the first opening 20a. . The lens cover 23 is fixed by the substrate 120 and the first light shielding member 5 and the second light shielding member 6. The lens cover 23 has a rectangular plate shape that is long in the Y-axis direction, and is formed of a transparent resin material such as acrylic or polycarbonate having light transmittance.

The lens cover 23 is a lens that controls the light distribution of most of the light emitted by the first light source 121, and has a plurality of lenses. The lens cover 23 is disposed on the light-emitting module 21 in a manner of covering most of the first light sources 121. Specifically, when the lens cover 23 and the plurality of first light sources 121 are viewed from above, each lens formed on the lens cover 23 corresponds to each first light source 121 in a one-to-one manner. Each lens of the lens cover 23 When the light emitted by each corresponding first light source 121 penetrates, the light distribution angle of the transmitted light is controlled.

In addition, a notch 231 is provided at the outer end of each of the pair of lens covers 23. Specifically, the lens cover 23 on the positive direction of the Y-axis is provided with a notch 231 at the end on the positive direction of the Y-axis. The lens cover 23 on the negative side of the Y-axis is provided with a notch 231 at the end on the negative side of the Y-axis. The notch 231 is formed in, for example, a trapezoidal shape in plan view with a small width on the side of the first opening 20a and a large width on the opposite side.

The pair of lens covers 23 control the light distribution of most of the first light sources 121 to emit light. Thereby, the pair of lens covers 23 become the light-emitting area of the illuminating unit 20. The pair of lens covers 23 are respectively long in the Y-axis direction, and the light-emitting area is also set long in the Y-axis direction. As described above, since the pair of speakers 41 and the pair of covers 42 are arranged to sandwich the illuminating portion 20 in the Y-axis direction, the pair of speakers 41 and the light-emitting area do not overlap when the light-emitting area is viewed from above.

[Container]

As shown in FIG. 2, the accommodating body 25 includes a first accommodating portion 251 and a second accommodating portion 252. The first accommodating portion 251 is a frame body that accommodates: a pair of light-emitting modules 21; a pair of lens covers 23; a first wireless module 46; and a second wireless module 47.

An opening 257a is formed in the center of the second accommodating portion 252, which becomes a part of the first opening 20a. In addition, the second accommodating portion 252 is fixed to the first accommodating portion 251 by a fastening member not shown.

The mounting board 262 is formed by a first mounting board 263 and a second mounting board 264.

The first mounting board 263 is mounted with the first circuit board 260 for the lighting unit 20. The first mounting plate 263 is formed in a substantially rectangular shape in plan view with the Y-axis direction being long. In addition, the first mounting plate 263 is provided with a cylindrical portion 272 which becomes a part of the first opening 20a. The cylindrical portion 272 is arranged at a position deviated from the positive direction side of the Y-axis in the first mounting plate 263. Therefore, the area of the first mounting plate 263 in the positive direction of the Y axis is larger than that of the cylindrical portion 272. In other words, the area on the negative side of the Y-axis is smaller than the cylindrical portion 272. When the cylindrical portion 272 is fixed to the first mounting plate 263, it communicates with the opening 257a of the second accommodating portion 252.

The second mounting board 264 mounts the second circuit board 270 for the audio unit 40 and the third circuit board 280. The second mounting plate 264 is formed in a substantially square shape in plan view, and ribs 264a are provided throughout the entire circumference. In addition, a large number of openings are formed at the bottom of the second mounting plate 264. The second mounting plate 264 is an example of the mounting plate. In addition, the first mounting plate 263 and the second mounting plate 264 may also be integrated. The first mounting plate 263 may also be an example of the mounting plate.

In addition, the second mounting plate 264 has a receiving support part 265 to support the second wireless module 47 in a predetermined posture. The accommodating support part 265 is a support platform for holding the second circuit board 270 and holding the second wireless module 47 in a freely detachable manner. The receiving support part 265 is formed integrally with the rib 264a, and is arranged at the end edge of the second mounting plate 264 on the negative side of the Y-axis. The housing support part 265 has a housing space 265a into which the second wireless module 47 is inserted. The accommodating support part 265 accommodating the second wireless module 47 inside refers to accommodating at least a part of the second wireless module 47 inside.

The storage support portion 265 has a storage portion main body 266, a pair of support portions 267, and a locking protrusion 268.

Compared with the rib 264a, the receiving portion body 266 is a square column-shaped pedestal that stands up in the negative direction of the Z-axis and supports the second wireless module 47. The accommodating portion main body 266 is long in the X-axis direction. A cavity is formed inside the receiving portion body 266, and the second wireless module 47 can be disposed. This cavity constitutes a part of the containing space 265a.

FIG. 6 is a plan view showing the housing support part 265 of the lighting device 1 of the embodiment.

As shown in FIGS. 5 and 6, a slit 266b for inserting the second wireless module 47 is formed between the pair of engagement recesses 269 on the end surface of the accommodating portion main body 266 on the negative direction side of the Z axis. That is, the slit 266b is an insertion hole connecting from the space between the pair of supporting parts 267 to the cavity of the receiving part body 266. The slit 266b is long in the X-axis direction. The slit 266b also constitutes a part of the receiving space 265a. The slit 266b is formed with a cutout portion 266c, and when the second wireless module 47 described later is housed in the housing support portion 265 in an upside-down state, it does not contact the second terminal 148b of the second wireless module 47.

The pair of support portions 267 protrude in the negative Z-axis direction from the end surface on the negative Z-axis direction side of the accommodating portion main body 266. The pair of support parts 267 are arranged in the longitudinal direction of the slit 266b, and sandwich the slit 266b from both sides. A space capable of accommodating a part of the second wireless module 47 is formed between the pair of supporting parts 267. This space constitutes a part of the storage space 265a.

Each of the pair of supporting parts 267 has an engaging recess 269 that is engaged with the second wireless module 47 to support the second wireless module 47 in a predetermined posture. The engaging recess 269 is a groove substantially parallel to the X-Z plane, and the engaging recess 269 can insert the second wireless module 47 described later from the negative direction of the Z axis toward the positive direction of the Z axis. That is, the width of the engaging recess 269 in the X-axis direction is slightly larger than the thickness of the substrate constituting the second wireless module 47 due to the dimensional tolerance. The length (width) L1 from one engagement recess 269 to the other engagement recess 269 is longer than the length (width) L2 in the X-axis direction of the slit 266b. The pair of engaging recesses 269 and the slit 266b are arranged on the same straight line, that is, in the X-axis direction. That is, the engaging recess 269 is formed in the positive direction of the Z-axis with a bottom surface that abuts against a pair of extension portions 147b of the second wireless module 47 described later. Thereby, the pair of supporting portions 267 can be respectively inserted into the pair of engaging recesses 269 to abut against the bottom surface of the pair of extension portions 147b, so that the second wireless module 47 can be held in a predetermined posture. That is, the pair of engaging recesses 269 are hooked to the second wireless module 47, which means that they engage with the second wireless module 47. The second wireless module 47 is supported in a predetermined posture. In this way, the second wireless module 47 is fixed to the accommodating support part 265.

The locking protrusion 268 is a protrusion formed between a pair of supporting parts 267. The locking protrusion 268 restricts the movement of the first terminal 148a so that the first terminal 148a connected to the second terminal 148b does not leave the second terminal 148b. The locking protrusion 268 is formed on the positive direction side of the Y-axis of the slit 266b when the supporting portion 265 is housed in a plan view.
