[Lighting Department]
The lighting section 20 has a long rectangular shape in the Y-axis direction. In other words, the longitudinal direction of the lighting unit 20 becomes the Y-axis direction. The illuminating unit 20 has a circular first opening 20a in a central portion. The first opening portion 20a is an opening portion for mounting, and the lighting portion 20 is attached to the ceiling member 11 via the first opening portion 20a. As a result, the lighting unit 20 is electrically connected to the suspended ceiling member 11. The lighting unit 20 includes a pair of light emitting modules 21 and a housing 25.

[Light-emitting module]
As shown in FIG. 2, the pair of light emitting modules 21 are fixed to the housing 25 by a fastening member 19 such as a screw. Specifically, the pair of light emitting modules 21 are arranged on the Y-axis positive direction side and the Y-axis negative direction side with respect to the first opening portion 20a so as to sandwich the first opening portion 20a. Although two light emitting modules 21 are used in this embodiment, one light emitting module 21 may be used.

As shown in FIGS. 2 and 3, the light emitting module 21 includes a substrate 120, a plurality of first light sources 121, a plurality of second light sources 122, and a plurality of wiring members 120 a.

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

The substrate 120 can also be thermally connected to a heat-radiating portion (not shown) in a manner to dissipate heat generated by the first light source 121 and the second light source 122. The heat radiating portion may be thermally connected to the exterior cover 12 so that the exterior cover 12 functions as a heat sink.

Most of the first light sources 121 are arranged on the substrate 120 in a long matrix shape in the Y-axis direction. A part of the plurality of second light sources 122 is aligned along the Y-axis direction on the X-axis forward direction side with respect to the plurality of first light sources 121. On the other hand, the plurality of second light sources 122 are aligned along the Y-axis direction on the negative X-axis direction side with respect to the plurality of first light sources 121. In other words, for the majority of the first light sources 121, the majority of the second light sources 122 arranged on the X-axis positive direction side and the majority of the second light sources 122 arranged on the X-axis negative direction side are sandwiched by the majority The light source 121 is arranged on the substrate 120.

Since the first light source 121 and the second light source 122 are directed toward the negative direction of the Z axis, the conventional light source is directed to the negative direction of the Z axis. The light emission direction, that is, each optical axis of the first light source 121 and the second light source 122 is substantially parallel to the Z-axis direction.

The first light guide plate 3 is arranged on the light emission direction side of the plurality of second light sources 122 arranged on the X-axis forward direction side. Further, a second light guide plate 4 is disposed on the light emitting direction side of the plurality of second light sources 122 arranged on the X-axis negative direction side. The second light source 122 on the X-axis positive direction side irradiates light onto the incident surface of the first light guide plate 3. The second light source 122 on the X-axis negative direction side irradiates light onto the incident surface of the second light guide plate 4. The second light sources 122 are arranged on the substrate 120 such that the light emission direction is directed toward the negative Z-axis direction. Specifically, the second light source 122 on the X-axis forward direction side is disposed such that the optical axis is substantially orthogonal to the incident surface of the first light guide plate 3 and faces the incident surface. The second light source 122 on the X-axis negative direction side is arranged such that the optical axis is substantially orthogonal to the incident surface of the second light guide plate 4 and faces the incident surface. That is, the second light source 122 is in a relationship substantially perpendicular to each incident surface of the first light guide plate 3 and the second light guide plate 4.

In addition, a gap is left 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. Specifically, the SMD type LED element is a packaged LED element in which an LED chip (light emitting element) is mounted in a cavity formed by a resin, and a phosphor-containing resin is sealed in the cavity. For example, a surface-mounted LED element that emits white light by using a combination of a blue LED chip and a yellow-containing phosphor resin is used as the first light source 121 and the second light source 122.

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. 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 such a structure, and a COB (Chip On Board) type module in which an LED chip is directly mounted on the substrate 120 may be used. 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, or organic ELs (Electro Luminescence) and ELs such as inorganic ELs. And other solid-state light-emitting elements.

In addition, since the light emitting module 21 on the other side has the same structure, the description thereof is omitted.

[Lens cover]

Toward the side. The lens cover 23 is fixed by the substrate 120, the first light shielding member 5, and the second light shielding member 6. The lens cover 23 has a long rectangular plate shape in the Y-axis direction, and is formed of a transparent resin material such as acrylic or polycarbonate having translucency.

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

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

These pair of lens covers 23 emit light by controlling light distribution from a plurality of first light sources 121. Thereby, the pair of lens covers 23 become a light emitting area of the illumination section 20. Since the pair of lens covers 23 are respectively long in the Y-axis direction, the light emitting area is also set to be 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 lighting portion 20 in the Y-axis direction, the pair of speakers 41 and the light emitting region do not overlap when viewed in plan.

[First wireless module, second wireless module]
As shown in FIG. 5, the first wireless module 46 is disposed in the notch 231 of the lens cover 23 on the Y-axis forward direction side. The first wireless module 46 is a wireless module that receives a wireless signal for the lighting unit 20. The first wireless module 46 is electrically connected to the first circuit board 260 for the lighting unit 20 through wiring (not shown). Thereby, the wireless signal received by the first wireless module 46 is transmitted to the lighting control section 13 located on the first circuit substrate 260.

The second wireless module 47 is disposed in the notch 231 of the lens cover 23 on the negative side of the Y-axis. The second wireless module 47 is a wireless module that receives a wireless signal for the audio unit 40. The second wireless module 47 is electrically connected to the second circuit board 270 for the acoustic unit 40 through wiring (not shown). Thereby, the wireless signal received by the second wireless module 47 is transmitted to the acoustic control unit 16 located on the second circuit board 270.

The wireless communication adopted by the first wireless module 46 and the second wireless module 47 is communication using electric waves (that is, visible light and infrared rays are excluded). The first wireless module 46 and the second wireless module 47 perform wireless communication according to wireless communication standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), BLE, or ZigBee (registered trademark).

The first wireless module 46 includes a capsule-shaped housing 461 and a wireless receiving unit (not shown), and is housed in the housing 461. The wireless receiving unit of the first wireless module 46 receives a wireless signal transmitted from an operation terminal for operating the lighting device 1 and outputs the wireless signal to the lighting control unit 13.

The second wireless module 47 includes a capsule-shaped housing 471 and a wireless receiving unit (not shown), and is housed in the housing 471. The wireless receiving unit of the second wireless module 47 receives a wireless signal transmitted from the operation terminal and outputs the wireless signal to the sound control unit 16.

Here, as long as the operation terminal is a device capable of wireless communication, for example, a mobile terminal such as a smart phone, a wireless remote control, etc. may be mentioned. The operation terminal outputs a wireless signal for the lighting section 20. The wireless signal for the lighting unit 20 is a signal for controlling the lighting unit 20. The wireless signal for the lighting unit 20 includes, for example, the following: a lighting instruction for lighting the first light source 121 and the second light source 122; an extinguishing instruction for lighting the first light source 121 and the second light source 122; or a selection Instruction, select a dimming ratio or a color temperature (light color) of the first light source 121 and the second light source 122.

The operation terminal outputs a wireless signal for the acoustic unit 40. The wireless signal for the acoustic section 40 is a signal for controlling the acoustic section 40. The wireless signal for the audio unit 40 includes, for example, the following: a start instruction to start the speaker 41; a stop instruction to stop the speaker 41; a volume instruction to adjust the volume; and sound data output by the speaker 41.

FIG. 8 is a side view showing the positional relationship between the first wireless module 46 and the lens cover 23 according to the embodiment. As shown in FIG. 8, the first wireless module 46 protrudes from the lens cover 23 toward the Z-axis negative direction side. In other words, the first wireless module 46 protrudes in a light emission direction from the light emitting area relative to the light emitting area. Specifically, the frame 461 of the first wireless module 46 protrudes from the lens cover 23 toward the Z-axis negative direction side. Because of this positional relationship, it is possible to suppress the situation where the lens cover 23 shields the wireless communication of the first wireless module 46. Moreover, in the housing 471, when the wireless receiving section of the first wireless module 46 is disposed on the Z-axis negative direction side than the lens cover 23, more stable wireless communication can be performed. The positional relationship between the second wireless module 47 and the lens cover 23 in the side view is the same as the positional relationship between the first wireless module 46 and the lens cover 23, and therefore description thereof is omitted.

As shown in FIG. 5, when the lens cover 23 is viewed from the top, the first wireless module 46 and the second wireless module 47 are arranged in a region surrounded by the wall portion 254 of the first receiving portion 251. Specifically, the first wireless module 46 is disposed in the notch 231 of the lens cover 23 on the Y-axis forward direction side, and is close to the wall portion on the Y-axis forward direction side. On the other hand, the second wireless module 47 is disposed in the notch 231 of the lens cover 23 on the negative Y-axis direction side, and is close to the wall portion on the negative Y-axis direction side. In this way, the first wireless module 46 and the second wireless module 47 are disposed at positions facing each other in the Y-axis direction with the pair of lens covers 23 forming a light-emitting area. Thereby, the light emitted from the light emitting area is blocked by the first wireless module 46 and the second wireless module 47. In addition, since the first wireless module 46 and the second wireless module 47 are arranged as far apart as possible within the first receiving section 251, the wireless signal for the lighting section 20 received by the first wireless module 46 is the same as that of the first wireless module 20. The wireless signals used by the acoustic unit 40 received by the two wireless modules 47 are less likely to cause interference.

[Lighting control section]
The lighting control unit 13 is electrically connected to the first light source 121, the second light source 122, and the first wireless module 46. The lighting control unit 13 controls, for example, a lighting circuit unit of the first light source 121 and the second light source 122, so that light emitted from the first light source 121 and the second light source 122 can be dimmed and toned. The lighting control unit 13 controls the first light source 121 and the second light source 122 based on a wireless signal for the lighting unit 20 received by the first wireless module 46. For example, the lighting control unit 13 may be controlled based on the wireless signal used by the lighting unit 20: only the majority of the first light sources 121 on the positive side of the Y axis are turned on; Lighting of the light source 121; only lighting of all the first light sources 121; lighting of only the majority of the second light sources 122 arranged on the X-axis positive direction side; Lighting of the second light source 122; or lighting of these combinations.

In other words, the translucent cover 7 may not be a transparent cover, but may be a diffusion cover having translucency and light diffusivity. In this case, the light-transmitting cover 7 may be a milky-white diffusion plate in which a light diffusion material is dispersed. Such a diffusion cover can be produced by resin-molding a light-transmitting resin material mixed with a light-diffusing material into a predetermined shape. As the light diffusing material, light reflective fine particles such as silicon dioxide particles can be used.

Specifically, the entire center of gravity of the lighting device 1 falls into the first opening portion 20 a by adjusting the weight balance of the constituent members forming the lighting device 1. Here, the center of gravity of the pair of speakers 41 is determined to be arranged in the first opening portion 20a in a plan view of the first opening portion 20a. For example, the weight of each of the pair of speakers 41 may be made equal, and the intervals from the first opening portion 20a to the pair of speakers 41 may be made equal.

In addition, the center of gravity that combines the first circuit substrate 260 and the second circuit substrate 270 is also arranged in the first opening portion 20a in a plan view of the first opening portion 20a. Here, if the first circuit board for the lighting section 20 is made as a single body, it is easy to become larger and heavier than the second circuit board 270 for the acoustic section 40. Therefore, in the present embodiment, the first circuit substrate 260 is divided into a main substrate 260a and a sub substrate 260b smaller in size than the main substrate 260a.

[action]
The lighting device 1 performs lighting and sound output desired by the user based on a wireless signal for the lighting section 20 and a wireless signal for the acoustic section 40 transmitted from the operation terminal. During reception, there may be interference between the wireless signal for the lighting unit 20 and the wireless signal for the audio unit 40. However, as described above, since the first wireless module 46 and the second wireless module 47 are arranged as far apart as possible in the first receiving section 251, the wireless signal for the lighting section 20 and the wireless signal for the acoustic section 40 are received at the same time. In this case, it is difficult for the wireless signals of each other to interfere.

Next, an operation during lighting in the lighting device 1 will be described.

The lighting control unit 13 controls the first light source 121 and the second light source 122 based on a wireless signal for the lighting unit 20 received by the first wireless module 46. The light emitted from the plurality of first light sources 121 is controlled by the light distribution of the lens of the lens cover 23 and penetrates the light-transmitting cover 7 and advances in the Z-axis direction of the lighting device 1.

A sound based on audio data is output from the pair of speakers 41. At the time of sound output, the vibration caused by the sound is generated from the pair of speakers 41. This vibration is also transmitted to the lighting section 20. For example, when the vibration from the pair of speakers 41 is not evenly transmitted to the lighting unit 20, the lighting unit 20 vibrates greatly, and the illumination light is greatly shaken. However, in this embodiment, since the center of gravity of the pair of speakers 41 is arranged in the first opening portion 20a in a plan view of the first opening portion 20a, each of the pair of speakers 41 becomes substantially equal. The vibration is transmitted to the lighting unit 20. Thereby, the illuminating part 20 is relatively difficult to shake, and can be used as illumination light with less shaking. In particular, in this embodiment, since the center of gravity of the entire lighting device 1 is arranged in the first opening portion 20a in a plan view of the first opening portion 20a, the entire lighting device 1 is installed on the building material in a well-balanced manner, making it difficult Shaky support structure.

Here, the lighting device 1 is supported by the building material through the first opening 20a. However, since the entire center of gravity of the at least one speaker 41 is disposed in the first opening 20a, vibration is transmitted from the at least one speaker 41 approximately equally To the lighting section 20. Thereby, the lighting part 20 becomes relatively hard to shake, and can be used as the illumination light with less shaking. Therefore, it is possible to suppress the situation where the vibration caused by the sound from the speaker 41 affects the lighting unit 20.

In addition, the device body 2 is long and includes a first opening portion 20 a at a central portion. A pair of speakers 41 are provided, and a pair of speakers 41 are provided at both ends in the longitudinal direction of the device body 2.

The main substrate 260 a is disposed on one side in the longitudinal direction with reference to the first opening 20 a in the device body 2. A sub substrate 260b and a second circuit substrate 270 are disposed on the other side.

Accordingly, since the first circuit substrate 260 includes the main substrate 260a and the sub substrate 260b, the center of gravity of the combination of the first circuit substrate 260 and the second circuit substrate 270 can easily fall within the first opening portion 20a.

In addition, the device body 2 includes an exterior cover 12 that houses the lighting section 20 and the acoustic section 40, and a cushioning material 43 is provided between the speaker 41 and the exterior cover 12.

Accordingly, since the cushioning material 43 is provided between the speaker 41 and the exterior cover 12, vibration generated by the sound output from the speaker 41 is absorbed by the cushioning material 43. Therefore, it is possible to suppress the vibration caused by the speaker 41 from being transmitted to the exterior cover 12 and the lighting unit 20 and the like housed in the exterior cover 12. Therefore, the situation where the vibration caused by the sound from the speaker 41 affects the lighting unit 20 is further suppressed.

In addition, the lighting device 1 includes a light guide plate (first light guide plate 3 and second light guide plate 4) so as to extend toward the outside of the exterior cover 12 and is attached to the exterior cover 12; and a light source (second light source 122) , The light is incident on the light guide plate.

Thereby, even if it is the illuminating device 1 provided with the light guide plate, it can suppress that the vibration caused by the sound from the speaker 41 affects the lighting part 20 and a light guide plate.

The light guide plates are provided in a pair so as to face each other.

With this, even if the lighting device 1 includes a pair of light guide plates facing each other, it is possible to suppress the situation where the vibration caused by the sound from the speaker 41 affects the lighting unit 20 and the pair of light guide plates.

The center of gravity of the lighting device 1 is disposed in the first opening portion 20a in the case of the first opening portion 20a in a plan view.

Because of this, the center of gravity of the lighting device 1 is arranged in the first opening portion 20a in a plan view of the first opening portion 20a. Therefore, the entire lighting device 1 is installed on the building material in a well-balanced manner, and becomes a support structure that is not easily shaken. Therefore, the vibration caused by the sound from the speaker 41 is not easily affected by the lighting unit 20.

In addition, if the center of gravity of the entire lighting device 1 is disposed in the first opening portion 20a in a plan view, the center of gravity of the pair of speakers 41 may not be disposed in the first opening portion 20a. The center of gravity combined by the circuit substrate 260 and the second circuit substrate 270 may not be disposed in the first opening portion 20a.
