Lighting unit

The present invention relates to a lighting unit.

FIG. 4 of Patent Document 1 discloses an illumination unit including an illumination device and a speaker device.

JP 2008-35133 A

In FIG. 4 of Patent Document 1, the lighting device and the speaker device are separated. The reason why the lighting device and the speaker device are separated is due to circumstances such as the fact that the manufacturing locations or manufacturing companies of the two are different, and the desire to increase variations in combinations of the speaker device and the lighting device.

When the illumination unit shown in FIG. 4 of Patent Document 1 is attached to the ceiling, the speaker device is suspended from the ceiling, and the illumination device is suspended from the speaker device. For this reason, a load due to gravity is applied to a connection portion between the speaker device and the ceiling and a connection portion between the speaker device and the lighting device. Furthermore, the speaker device vibrates by outputting sound, and a load caused by the vibration is applied to each of the connection portions. In particular, a load due to the weight of the speaker device and the lighting device and a large load due to vibration of the speaker device are applied to the connection portion between the ceiling and the speaker device. If this state continues for a long period of time, the connection portion between the lighting unit and the ceiling may deteriorate, and the attachment of the lighting unit to the ceiling may become unstable. Such a problem also occurs when the lighting unit is attached to a portion other than the ceiling.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an illumination unit that includes a speaker device and an illumination device, and that can reduce a load caused by vibration of the speaker device applied to a connection portion with a ceiling or the like. To do.

In order to achieve the above object, a lighting unit according to the present invention comprises:
A lighting device;
A hanging part for hanging the lighting device;
A speaker device disposed on the lighting device and outputting sound;
With
A vibration absorbing member that absorbs vibration generated by sound output of the speaker device is interposed between the speaker device and the lighting device.
It is characterized by that.

According to the present invention, it is possible to provide an illumination unit that includes a speaker device and an illumination device, and can reduce a load caused by vibration of the speaker device applied to a connection portion with a ceiling or the like.

It is a figure which shows the cross section etc. of the illumination unit which concerns on one embodiment of this invention. It is a disassembled perspective view about a part of illumination unit of FIG. It is the figure which looked at a part of inner surface of the speaker apparatus of FIG. 1 from the center side. It is the figure which looked at the other part of the inner surface of the speaker apparatus of FIG. 1 from the center side. It is the figure which looked at the speaker apparatus etc. of FIG. 1 from upper direction. It is a schematic sectional drawing of the speaker apparatus which shows the relationship between the housing | casing and speaker of the speaker apparatus of FIG. It is an internal block diagram of the speaker apparatus of FIG.

As shown in FIG. 1, the lighting unit 1 includes a lighting device 10, a suspension unit 20, and a speaker device 30. The lighting unit 1 is used by being attached to a power supply unit 3a installed on the ceiling 3 of the room. The power supply unit 3a is configured by a hooking ceiling, a hooking rosette, and the like, and the lighting unit 1 is suspended by engaging a hook metal fitting of the power supply connecting unit 21 described later. The power supply unit 3a receives supply of commercial power from the outside and supplies power to the lighting unit 1 via a hook. In addition, in FIG. 1, the power supply part 3a and the ceiling 3 were drawn as schematic sectional drawing, and the internal structure was abbreviate | omitted. A speaker device 30 is attached to the lighting device 10. The lighting device 10 is suspended from the ceiling 3 by the suspension unit 20.

The illumination device 10 includes an illumination top plate 11, a cover 12, a light emitting unit 13, and a control unit 14. In FIG. 1, the light emitting unit 13 and the control unit 14 are drawn as schematic cross-sectional views, and hatching and internal structures representing cross sections are omitted.

The lighting top plate 11 is made of metal or the like. The illumination top plate 11 has a disc shape (a donut plate shape) having a through hole in the center (see FIGS. 2 and 4). A light emitting unit 13 and a control unit 14 are attached to the illumination top plate 11 (see FIG. 1). The control unit 14 and the light emitting unit 13 are connected via a wiring (not shown). Further, the illumination top plate 11 is provided with a through hole 11a through which a signal line L3 described later passes (see FIGS. 1 and 2).

The light emitting unit 13 is composed of an LED (Light Emitting Diode) and its driving device. The light emitting unit 13 emits light when power is supplied.

The control unit 14 includes a reception unit, a drive circuit, and the like. Power is supplied to the control unit 14 from the power supply unit 3a via a power supply connection unit 21 described later (details will be described later), and the reception unit, the drive circuit, and the like are controlled using the supplied power. Based on the user's remote control operation, the remote control device of the lighting device 10 converts the operation signal into an infrared signal using a photoelectric conversion element, and transmits the infrared signal. The receiving unit includes a photoelectric conversion element that receives an infrared signal. A receiving part receives the infrared signal transmitted from the remote control apparatus of the illuminating device 10, and converts the received infrared signal into an electrical signal with a photoelectric conversion element. And a receiving part transmits an electric signal to a drive circuit. The drive circuit turns on the light emitting unit 13 by supplying the power supplied from the power supply unit 3 a to the light emitting unit 13 according to the electrical signal received from the receiving unit, and does not supply this power to the light emitting unit 13. The light emitting unit 13 is turned off. In addition, the drive circuit performs dimming to adjust the brightness (light emission amount) of the light emitting unit 13 by adjusting the amount of power supplied to the light emitting unit 13 in accordance with the electrical signal received from the receiving unit. Specifically, the drive circuit adjusts the current flowing through the light emitting unit 13 in accordance with the electrical signal received from the receiving unit. In this way, the control unit 14 controls lighting, extinction, dimming, and the like of the light emitting unit 13 based on the operation by the user's remote controller.

The cover 12 is a member made of synthetic resin or the like, and covers the light emitting unit 13 and the control unit 14 from the lower side. The cover 12 is fixed to the illumination top plate 11 by an appropriate method such as hooking or screwing. The cover 12 scatters and emits light from the light emitting unit 13.

With the above configuration, power is supplied to the lighting device 10 from the power supply unit 3a via the power supply connection unit 21 described later. And the light emission part 13 light-emits under control of the control part 14 with this electric power. Further, the light from the light emitting unit 13 is scattered by the cover 12 and emitted to the outside of the illumination device 10. Thereby, the room in which the ceiling 3 is provided is illuminated.

The hanging part 20 is a member that extends upward (in the direction toward the ceiling 3) from the lighting device 10 (see FIG. 1). The suspending unit 20 suspends the lighting device 10 from the power supply unit 3a. As shown in FIG. 1, the suspension part 20 includes a power supply connection part 21, a first cylindrical member 22, and a second cylindrical member 23. In FIG. 1, the power supply connection portion 21 is drawn as a schematic cross-sectional view, and the internal structure is omitted.

The power supply connection part 21 is a member that attaches the lighting unit 1 to the ceiling 3 by being attached to the power supply part 3a, and supplies power supplied from the power supply part 3a to the lighting device 10. As shown in FIG. 1, the power supply connection part 21 is provided with the substantially cylindrical power supply connection part main body 21a and the two nail | claws 21b.

The power supply connection part main body 21a is provided with a hook metal fitting, and accommodates an adapter etc. inside. The user inserts the hook metal into the insertion hole of the power supply unit 3a and rotates the power supply connection unit 21 to attach the power supply connection unit 21 to the power supply unit 3a. When the hook is engaged with the power supply unit 3a, the power supply connection unit 21 is prevented from dropping and dropping. The adapter in the power supply connection unit 21 converts AC power supplied from the power supply unit 3a into DC power.
One end portions of the wires L1 and L2 are connected to the adapter in the power supply connecting portion main body 21a via respective connectors. The other end of the wiring L1 is connected to the speaker device 30 via a connector. The other end of the wiring L2 is connected to the lighting device 10 via a connector. AC power (commercial power) is supplied from the power supply unit 3a to the adapter of the power supply connection unit main body 21a. The adapter includes a rectifier, a smoothing circuit, and the like, converts the supplied AC power into DC power for the speaker device 30, and supplies the DC power to the speaker device 30 via the wiring L1. Further, the adapter converts the supplied AC power into DC power for the lighting device 10 and supplies it to the lighting device 10 via the wiring L2.
As described above, the power supply connection unit main body 21a has a role of supplying the power supplied from the power supply unit 3a to the speaker device 30 and the lighting device 10. The wiring L1 and the wiring L2 are connected in parallel to the power supply connecting portion main body 21a. Thereby, the power from the power supply unit 3a is individually supplied from the power supply connection unit main body 21a to the speaker device 30 and the lighting device 10.

Two through holes are formed in the outer peripheral surface of the casing of the power supply connection main body 21a. And the claw 21b protrudes from each of these two through holes. Note that the number of claws 21b may be three or more. The claws 21b are each urged toward the outside of the power supply connection portion main body 21a by an elastic member such as a spring inside the power supply connection portion main body 21a. The claw 21b is formed in a wedge shape so that the tip is thin. For this reason, when a pressing force is applied to the lower surface of the tip of the claw 21b, the claw 21b is retracted into the power supply connecting portion main body 21a.

The first cylindrical member 22 is a substantially cylindrical member formed of a metal plate or the like. As shown in FIG. 1, the 1st cylindrical member 22 is provided with the cylindrical part 22a, the upper end flange 22b, and the lower end flange 22c. The cylindrical portion 22a is a portion having a cylindrical shape. The upper end flange 22b protrudes from the upper end (end on the ceiling 3 side) of the cylindrical portion 22a toward the inside in the radial direction (horizontal direction) of the cylindrical portion 22a. The horizontal direction is the in-plane direction of the ceiling 3. The lower end flange 22c protrudes from the lower end (end opposite to the ceiling 3) of the cylindrical portion 22a toward the outside in the radial direction (horizontal direction) of the cylindrical portion 22a (see FIG. 2). The upper end flange 22b and the lower end flange 22c have a donut shape when viewed from above.

The second cylindrical member 23 is a substantially cylindrical member made of synthetic resin. As shown in FIG. 1, the second cylindrical member 23 includes a cylindrical portion 23a, an upper flange 23b, and a lower end flange 23c. The cylindrical portion 23a is a portion having a cylindrical shape. The upper flange 23b protrudes inward in the radial direction (horizontal direction) of the cylindrical portion 23a from the vicinity of the upper end that is a predetermined distance away from the upper end of the cylindrical portion 23a. The lower end flange 23c protrudes from the lower end of the cylindrical portion 23a toward the outside in the radial direction (horizontal direction) of the cylindrical portion 23a. When viewed from above, the upper flange 23b and the lower end flange 23c have a donut shape (see FIG. 2).

The inner peripheral surface of the cylindrical portion 22a of the first cylindrical member 22 and the outer peripheral surface of the cylindrical portion 23a of the second cylindrical member 23 have substantially the same diameter. The first cylindrical member 22 and the second cylindrical member 23 are combined to form one cylindrical member 24 so that the first cylindrical member 22 covers the second cylindrical member 23 from above. At this time, the lower end flange 22c and the lower end flange 23c are combined to form one flange. Furthermore, the upper end flange 22b and the upper flange 23b are spaced apart from each other in the vertical direction (see FIG. 1).

A plurality of through holes are provided in a flange (a flange of the cylindrical member 24) in which the lower end flange 22c and the lower end flange 23c are combined. Each of the plurality of through holes is a communication between a through hole provided in the lower end flange 22c and a through hole provided in the lower end flange 23c. Hereinafter, these through holes are referred to as communication holes. A screw 9b passes through these communication holes. The illumination top plate 11 is formed with a plurality of screw holes that are screwed into the screws 9b in correspondence with these communication holes (see FIG. 1). Each screw 9b is screwed into each screw hole of the illumination top plate 11 through each communication hole. Thereby, the cylindrical member 24 (the 1st cylindrical member 22 and the 2nd cylindrical member 23) is attached to the center of the upper surface of the illumination top plate 11 (illuminating device 10) so that rotation is impossible.

In this embodiment, since both the first cylindrical member 22 and the second cylindrical member 23 are overlapped and fixed to the lighting top plate 11 by the screw 9b, both of them are not fixed to each other. Good. In addition, both may be fixed to each other by bonding or the like. Moreover, the cylindrical member 24 may be integrally formed by integrally molding the first cylindrical member 22 and the second cylindrical member 23 by insert molding or the like.

Further, the cylindrical portion, which is a portion where the cylindrical portion 22a and the cylindrical portion 23a of the cylindrical member 24 are combined, includes a rectangular through hole 24a and a through hole 24b (see FIG. 1). The through hole 24a and the through hole 24b are different in the circumferential dimension and the vertical dimension of the cylindrical portion. A wiring L1 that connects the power supply connection portion 21 and the speaker device 30 passes through the through hole 24b. The dimension of the through hole 24b (particularly the dimension along the vertical direction) is larger than the dimension of the through hole 24a. The width of the through hole 24a (the dimension along the circumferential direction) is substantially the same as the width of the claw 33aa of the elastic portion 33a. The width | variety of the collar through-hole 24b is substantially the same as the width | variety of the nail | claw 33ba of the elastic part 33b. Here, the width of the claw 33ba of the elastic portion 33b is different from the width of the claw 33aa of the elastic portion 33a. A claw 33aa (see FIG. 3A, which will be described later in detail) enters into the through hole 24a. Similarly, a claw 33ba (see FIG. 3B, which will be described in detail later) having substantially the same width enters the through hole 24b. Since the width of the through hole 24a is smaller than the width of the claw 33ba, the claw 33ba does not enter the through hole 24a. Therefore, when the tubular member 24 and the speaker device 30 are combined, the positional relationship between the tubular member 24 and the speaker device 30 (the rotation angle of the speaker device 30 with respect to the tubular member 24 when viewed from above) is unique. It is decided.

The claw 21b of the power supply connecting portion 21 is caught on the lower surface of the upper flange 23b (see FIG. 1). Thus, the cylindrical member 24 is attached to the power supply connection portion 21 so as not to drop off from the power supply connection portion 21. The lighting device 10 is attached to the tubular member 24, and the speaker device 30 is attached to the lighting device 10. For this reason, the weights of the speaker device 30 and the lighting device 10 are substantially loaded on the upper flange 23b. For this reason, it is desirable that the upper flange 23b is reinforced by a reinforcing rib or the like so as not to be damaged or deformed. For example, the reinforcing rib may be formed integrally with the upper flange 23b.

The upper end flange 22b is located closer to the ceiling 3 than the upper flange 23b (see FIG. 1). Further, the upper flange 23b and the upper end flange 22b are separated by a distance that allows the claw 21b to enter between them. Further, the claw 21b of the power supply connecting portion 21 is hooked on the lower surface of the upper end flange 22b in the same manner as the upper flange 23b. For this reason, when the tab 21b is hooked on the lower surface of the upper flange 23b, even if the tubular member 24 to which the lighting device 10 is attached may fall off from the power connection portion 21, the tab 21b It catches on the upper end flange 22b. Thereby, possibility that the illuminating device 10 etc. will drop can be reduced. Furthermore, since the upper end flange 22b is made of metal, it is stronger than the upper flange 23b. Therefore, the upper end flange 22b can more reliably prevent the dropout.

Further, both the upper flange 23b and the upper end flange 22b are configured such that the claws 21b are hooked. As a result, the attachment position of the cylindrical member 24 can be close to or far from the ceiling 3. Thus, the user can adjust the mounting position of the lighting unit 1. Further, when the power supply unit 3a is short, the claw 21b may be hooked on the upper end flange 22b, so that the lighting unit 1 can be attached according to the length of the power supply unit 3a. In addition, the attachment method to the power supply connection part 21 of the cylindrical member 24 is not restricted above, and may be performed by an appropriate method. Moreover, the cylindrical member 24 and the power supply connection part 21 may be integrated.

The power supply connection part 21 is attached to the power supply part 3a, and the cylindrical member 24 is attached to the power supply connection part 21, whereby the upper part of the hanging part 20 is attached to the power supply part 3a. On the other hand, the lighting device 10 is fixed to the lower part of the hanging part 20. With such a configuration, the suspension unit 20 suspends the lighting device 10 (and the speaker device 30) so as not to drop off from the power supply unit 3a.

The speaker device 30 is a device that includes at least speakers 38a, 38b, and 38c (see FIGS. 2 and 4). Hereinafter, the speakers 38a, 38b, and 38c may be collectively referred to as the speaker 38. The speaker device 30 outputs sound from the speaker 38. Here, “sound” refers to all things composed of sounds and voices, and includes music including songs, music not including songs, sound effects, and the like. In this embodiment, the speaker device 30 includes a receiving unit 36 and a control unit 37 in addition to the speaker 38 (see FIG. 6). The receiving unit 36, the control unit 37, and the like operate with electric power supplied from the power supply unit 3a via the power supply connection unit 21 and the wiring L1. In FIG. 1, the speaker device 30 is drawn as a schematic cross-sectional view, and the internal structure is omitted.

The receiving unit 36 is composed of a communication module or the like, and is controlled by a control unit 37 described later. The receiving unit 36 receives an audio signal transmitted in accordance with a DLNA (Digital Living Network Alliance) standard from a sound source device such as a digital media server (DMS: Digital Media Server). For example, DMS includes a personal computer, a set top box, a digital camera, a video camera, a multifunctional portable terminal, and the like. The receiving unit 36 receives audio signals transmitted in accordance with a predetermined standard such as Bluetooth (registered trademark) from various sound source devices such as various audio devices, personal computers, and multifunctional portable terminals. Further, the receiving unit 36 receives a command signal such as a signal indicating the size of the volume transmitted from the various sound source devices or the remote control device attached to the lighting unit 1 and transmits the command signal to the control unit 37. (See FIG. 6).

The control unit 37 includes a microcomputer and an amplifier. The control unit 37 performs D / A (Digital-to-Analogue) conversion on the audio signal input from the reception unit 36, and amplifies the converted signal by an amplifier controlled by a microcomputer. Then, the control unit 37 outputs the amplified signal to the speaker 38 (see FIG. 6). The speaker 38 outputs sound according to the signal output from the amplifier. As a result, sound is output from the speaker 38. In addition, the control unit 37 (microcomputer) changes the amplification level of the signal level of the amplifier in accordance with the command signal received by the receiving unit 36, and changes the volume (volume) of the sound flowing from the speaker 38.

The speaker device 30 in this embodiment includes an insertion hole. The hanging part 20 is inserted into the insertion hole (see FIG. 1). The external shape of the speaker device 30 is a housing made of a synthetic resin having a substantially donut shape surrounding the hanging portion 20. Further, the speaker device 30 includes a flange 31 projecting outward at the lower end portion of the outer peripheral surface thereof. The flange 31 is provided with a step in the vertical direction according to the shape of the illumination top plate 11. A plurality of (here, four) flanges 31 are provided (see FIG. 4). Each flange 31 has a through hole through which the screw 9a passes (see FIG. 2). The illumination top plate 11 is formed with a plurality of screw holes that are screwed with the screws 9a passing through the through holes. Each screw 9 a passes through each through hole and is screwed into a screw hole of the illumination top plate 11, whereby each flange 31 is fastened and fixed to the illumination device 10 by each screw 9 a. Thus, the speaker device 30 is attached to the upper surface of the illumination top plate 11 (illumination device 10) in a non-rotatable manner.

When the screw 9a passing through the through hole of each flange 31 is screwed into the screw hole of the illumination top plate 11 (when fastened and fixed), the vibration absorbing member 43a and the vibration absorbing member 43b are sandwiched as washers (washers). . Each of the vibration absorbing member 43a and the vibration absorbing member 43b has a donut shape having a through hole in the center through which the screw 9a passes (see FIG. 2). The vibration absorbing member 43a is sandwiched between the head of the screw 9a and the flange 31. The vibration absorbing member 43b is sandwiched between the flange 31 and the illumination top plate 11 (the upper surface of the illumination device 10) (see FIG. 1).

The vibration absorbing member 43a and the vibration absorbing member 43b are formed of an appropriate material such as a synthetic resin such as PBT (PolyButylene Terephthalate), natural rubber, or the like. Thus, the vibration absorbing member 43a and the vibration absorbing member 43b have elasticity and absorb vibration. In this embodiment, the vibration absorbing member 43a and the vibration absorbing member 43b are for absorbing vibration caused by the sound output of the speaker device 30. The vibration absorbing member 43a makes it difficult to transmit the vibration of the speaker device 30 to the screw 9a. Further, the vibration absorbing member 43a makes it difficult to loosen the screw 9a. The vibration absorbing member 43 b makes it difficult to transmit the vibration of the speaker device 30 to the lighting device 10. Furthermore, the vibration absorbing member 43b makes it difficult to apply an extra load caused by vibration to a fixed portion such as a flange portion of the cylindrical member 24 between the lighting device 10 and the hanging portion 20.

The vibration absorbing member 42 is formed of an appropriate material such as a synthetic resin such as PBT or natural rubber. The vibration absorbing member 42 has elasticity and absorbs vibration. In addition, a vibration absorbing member 42 is disposed between the lower surface of the speaker device 30 and the upper surface of the illumination top plate 11 of the illumination device 10 (see FIG. 1). The vibration absorbing member 42 is sandwiched between the speaker device 30 and the lighting device 10.

In this embodiment, the vibration absorbing member 43b and the vibration absorbing member 42 are interposed between the speaker device 30 and the lighting device 10 (see FIG. 1). For this reason, the speaker apparatus 30 and the illuminating device 10 do not contact directly (especially surface contact). By virtue of the vibration absorbing member 43 b and the vibration absorbing member 42, the vibration of the speaker device 30 is not easily transmitted to the lighting device 10. Further, since the vibration absorbing member 43b and the vibration absorbing member 42 are located between the lighting device 10 and the hanging portion 20, an extra load caused by vibration is applied to a fixed portion such as a flange portion of the cylindrical member 24. Make it harder.

On the inner surface of the speaker device 30, concave portions 32a and 32b are formed at two opposing positions (see FIG. 4).

The elastic portion 33a is a plate-like member, and extends toward the cylindrical member 24 and then downwards from an opposing surface of the inner surface of the concave portion 32a facing the cylindrical portion of the cylindrical member 24 (FIG. 3A). reference). A claw 33aa is provided at the lower end of the elastic portion 33a. The claw 33aa protrudes toward the cylindrical member 24 and enters the through hole 24a provided in the cylindrical member 24. Since the elastic portion 33a is a plate-like member, the elastic portion 33a can be elastically deformed so that the claw 33aa moves toward the facing surface.

The elastic portion 33b is a plate-like member, and extends from the opposite surface of the inner surface of the recess 32b facing the cylindrical portion of the cylindrical member 24 toward the cylindrical member 24 and then downwards (FIG. 3B). reference). A claw 33ba is provided at the lower end of the elastic portion 33b. The claw 33ba protrudes toward the tubular member 24 and enters the through hole 24b provided in the tubular member 24. Since the elastic portion 33b is a plate-like member, it can be elastically deformed so that the claw 33ba moves toward the opposing surface.

The claw 33aa enters the through hole 24a, and the claw 33ba enters the through hole 24b, whereby the speaker device 30 is positioned. The claw 33aa and the claw 33ba are mainly used for positioning the speaker device 30 (see FIGS. 3A and 3B).

The vibration absorbing member 44 is disposed in the vicinity of the recesses 32a and 32b on the inner surface of the speaker device 30 (see FIGS. 3A and 3B). The vibration absorbing member 44 is formed of an appropriate material such as a synthetic resin such as PBT or natural rubber. The vibration absorbing member 44 has elasticity and absorbs vibration. The vibration absorbing member 44 is sandwiched between the speaker device 30 and the cylindrical member 24 (see FIG. 1). The inner surface of the speaker device 30 is separated from the outer surface of the tubular member 24. As described above, the vibration absorbing member 44 is interposed between the speaker device 30 and the cylindrical member 24, and the speaker device 30 and the cylindrical member 24 are not in direct contact (particularly surface contact). In addition, you may contact about parts which cannot transmit vibration substantially, such as a nail | claw 33aa and a nail | claw 33ba. By virtue of the vibration absorbing member 44, vibration due to the sound output of the speaker device 30 is not easily transmitted to the tubular member 24 (hanging portion 20). Furthermore, the vibration absorbing member 44 makes it difficult to apply an extra load caused by vibration to a fixed portion between the lighting device 10 and the hanging portion 20 and a location where the hanging portion 20 is attached to the power supply unit 3a. Here, specifically, the fixed portion is a flange portion of the cylindrical member 24. The attachment location is specifically a connection portion between the power supply connection portion 21 and the power supply portion 3a.

The upper surface of the speaker device 30 is provided with inclined surfaces 39a and 39b inclined with respect to the horizontal direction (see FIGS. 2 and 5). In this embodiment, the inclined surfaces 39a and 39b are formed by curved surfaces. Note that the inclined surfaces 39a and 39b may be configured by flat surfaces. The inclined surfaces 39a and 39b are provided with exposure holes. Through these exposure holes, the sound emitting surfaces (surfaces on which sound is output) of the speakers 38 a and 38 b are exposed in an inclined state with respect to the ceiling 3. Further, the upper surface of the speaker device 30 is provided with a depression lowered by one step. An exposure hole for exposing the sound emitting surface of the speaker 38c is provided in this recess. Here, the speaker 38c extends in the vertical direction and is arranged in a direction toward the ceiling 3. In this way, the sound emission directions of the speakers 38a, 38b, and 38c are different. Thereby, sound can be effectively diffused. Further, the sound may be diffused by covering the sound emitting surface of the speaker 38 with a cover member drawn by a dotted line in FIG. The sound output from the speaker 38 is diffused by the ceiling 3 or a predetermined member, and efficiently reaches a user (sound listener) in the room.

The lighting unit 1 further includes a rotation suppressing member 41. The rotation suppressing member 41 is fixed to a predetermined position on the upper surface of the speaker device 30 with an adhesive, a double-sided tape, or the like. The rotation suppression member 41 is sandwiched between the upper surface of the speaker device 30 and the ceiling 3 (see FIG. 1). As shown in FIG. 1, the rotation suppressing member 41 includes a first member 41a and a second member 41b. The 1st member 41a is a member comprised from sponge, rubber | gum, etc., and is a member with a big friction coefficient. The second member 41b is formed of a synthetic resin, natural rubber, or the like and has elasticity. The second member 41b is more flexible than the first member 41a, and is a member that mainly absorbs vibration of the speaker device 30. The first member 41a and the second member 41b are fixed to each other by an adhesive, a double-sided tape, or the like. The rotation suppressing member 41 may be a single member. The rotation suppressing member 41 has an appropriate shape such as a rectangular parallelepiped shape. The rotation suppression member 41 makes it difficult for the speaker device 30 to rotate with respect to the ceiling 3 due to friction generated between the ceiling 3 and the first member 41 a in contact with the ceiling 3. Further, the rotation suppressing member 41 makes it difficult to transmit the vibration of the speaker device 30 to the ceiling 3 by the first member 41a and the second member 41b. If the rotation suppression member 41 is not provided and the speaker device 30 is in direct contact with the ceiling 3, the speaker device 30 rotates due to a reaction from the ceiling 3 due to vibration of the speaker device 30. There is a risk of it. In this embodiment, the rotation suppressing member 41 is interposed between the ceiling 3 and the speaker device 30. For this reason, the rotation suppression member 41 makes it difficult to transmit the vibration of the speaker device 30 to the ceiling 3. Thereby, the rotation suppression member 41 prevents the speaker device 30 from rotating due to a reaction from the ceiling 3 or the like.

The lighting device 10 and the speaker device 30 are connected via a signal line L3 (see FIG. 1). Specifically, the control unit 14 of the lighting device 10 and the control unit 37 of the speaker device 30 are connected via a signal line L3 that passes through a through hole 11a provided in the lighting top plate 11. Then, the control unit 14 and the control unit 37 exchange control signals and the like via the signal line L3 (see FIG. 6). The exchange of signals between the control unit 14 and the control unit 37 may be one-way. Accordingly, the lighting device 10 and the speaker device 30 can exchange information or operate in cooperation with each other.

The control unit 37 supplies a control signal designating the light emission amount according to the volume of the sound output from the speaker 38 to the control unit 14 via the signal line L3 (see FIG. 6). The control unit 37 stores in advance a correspondence table in which the sound volume and the light emission amount are associated with each other. For example, the volume and the light emission amount may be defined by, for example, the power supply amount. The control unit 37 refers to the correspondence table and acquires the light emission amount corresponding to the volume of the sound output from the speaker 38. Then, the control unit 37 supplies the control unit 14 with a control signal that specifies the acquired light emission amount. The control unit 14 performs dimming by adjusting the amount of power supplied to the light emitting unit 13 based on the light emission amount specified by the supplied control signal. Thereby, the illumination device 10 and the speaker device 30 can perform a coordinated operation.

The control unit 14 supplies a control signal designating a sound volume corresponding to the light emission amount to the control unit 37 via the signal line L3. The control unit 14 stores in advance a correspondence table in which the light emission amount and the sound volume are associated with each other. In this correspondence table, the sound volume and the amount of light emission are defined by the amount of power supply. The control unit 14 refers to the correspondence table and acquires a volume corresponding to the light emission amount of the light emitting unit 13. Then, the control unit 14 supplies the control unit 37 with a control signal designating the acquired volume. The control unit 37 performs adjustment so that the supplied control signal has a specified volume. Thereby, the illumination device 10 and the speaker device 30 can perform a coordinated operation.

The outline of the assembly method of the lighting unit 1 will be described.

The power supply connection part 21 to which the wiring L1 and the wiring L2 are connected is attached to the power supply part 3a. The cylindrical member 24 is attached to the illumination top plate 11 to which the light emitting unit 13, the control unit 14, and the vibration absorbing member 42 are attached by screws 9b. The vibration absorbing member 42 is attached to the upper surface of the illumination top plate 11 with a double-sided tape, an adhesive, or the like. Let the illumination top plate 11 to which the cylindrical member 24 is attached be a member A.

Also, the vibration absorbing member 44 is attached to the inner surface of the speaker device 30 with double-sided tape, adhesive, or the like. Further, the rotation suppressing member 41 is attached to the upper surface of the speaker device 30. Thereafter, the speaker device 30 is attached to the member A so that the cylindrical member 24 passes from the top to the center. At this time, the claw 33aa of the elastic portion 33a is inserted into the through hole 24a. Further, the claw 33ba of the elastic portion 33b is inserted into the through hole 24b. In this way, the speaker device 30 is aligned. When the speaker device 30 is moved from the upper side to the lower side, the claws 33aa and 33ba are pushed by the outer surface of the tubular member 24, and the claws 33aa and 33ba are moved away from the tubular member 24. 33b is elastically deformed. When the claws 33aa and 33ba reach the through holes 24a and 24b, the claws 33aa and 33ba enter the through holes 24a and 24b, and the elastic portions 33a and 33b return to the original state. Further, when the speaker device 30 is moved from the upper side to the lower side, the vibration absorbing member 44 slides on the outer surface of the cylindrical member 24. Further, the vibration absorbing members 43a and 43b are sandwiched, and the speaker device 30 is fixed to the member A with screws 9a. At this time, the signal line L3 is connected to the control unit 14 and connected to the speaker device 30. The member assembled in this way is referred to as member B.

Then, the member B is lifted from the lower side toward the ceiling 3, and the power supply connection portion 21 is passed through the cylindrical member 24. At this time, the upper end flange 22b of the first cylindrical member 22 pushes the claw 21b, and the claw 21b is retracted into the power supply connecting portion main body 21a. Thereafter, when the claw 21b passes through the upper end flange 22b, the claw 21b protrudes from the power supply connecting portion main body 21a and enters a space provided between the upper end flange 22b and the upper flange 23b of the second tubular member 23. As a result, the claw 21b is hooked on the upper end flange 22b, so that the member B is suspended from the power supply connecting portion 21 at the first position. Further, when the member A is lifted toward the ceiling 3, the upper flange 23b pushes the claw 21b, and the claw 21b is retracted into the power supply connecting portion main body 21a. Thereafter, when the claw 21b passes through the upper flange 23b, the claw 21b protrudes from the power supply connecting portion main body 21a and enters the space below the upper flange 23b of the second cylindrical member 23. As a result, the claw 21b is hooked on the upper flange 23b, so that the member B is suspended from the power supply connecting portion 21 at the second position closer to the ceiling 3 than the first position. Note that the rotation suppression member 41 is sandwiched between the ceiling 3 and the speaker device 30 regardless of whether the member B is suspended at the first position or the member B is suspended at the second position. However, when the member B is suspended at the second position, the rotation suppressing member 41 is further deformed and is sandwiched between the ceiling 3 and the speaker device 30.

Then, the wiring L1 and the wiring L2 are connected to the speaker device 30 and the control unit 14, respectively. Then, the cover 12 is attached to the lighting top plate 11. Thereby, the lighting unit 1 is attached to the power supply unit 3 a of the ceiling 3.

In this embodiment, with the above-described configuration, the lighting unit 1 suspends the lighting device 10 from a predetermined portion of the ceiling 3 in a state of being separated from the ceiling 3 and the lighting device 10 is suspended from the predetermined portion. The speaker device 30 is disposed between the lighting device 10 and the ceiling 3 and outputs sound (see FIG. 1). The hanging part 20 extends from the lighting device 10 toward the ceiling 3 (upward). Here, the predetermined position of the ceiling 3 is the power supply unit 3a. A vibration absorbing member 43 b and a vibration absorbing member 42 that absorb vibration of the speaker device 30 are interposed between the speaker device 30 and the lighting device 10. For this reason, the vibration of the speaker device 30 is absorbed by the vibration absorbing member 43 b and the vibration absorbing member 42. Thereby, the vibration of the speaker device 30 is not easily transmitted to the lighting device 10. Here, the fact that the vibration of the speaker device 30 is not transmitted at all to the lighting device 10 also means that the vibration is not easily transmitted to the lighting device 10. And it becomes difficult to apply an extra load caused by vibration of the speaker device 30 to a fixed portion (for example, a flange portion of the cylindrical member 24) between the lighting device 10 and the hanging portion 20 or the like. Here, the fact that no extra load is applied to the fixed portion means that the extra load is hardly applied to the fixed portion. If an extra load is applied, there is a high possibility that the lighting device 1, particularly the lighting device 10, will drop off due to damage to the fixed portion. However, according to the configuration of the present embodiment in which it is difficult to apply an extra load, the lighting device 10 can be stably suspended from the power supply unit 3 a of the ceiling 3.

In this embodiment, the vibration absorbing member 43b and the vibration absorbing member 42 are interposed between the speaker device 30 and the lighting device 10 by the above-described configuration (see FIG. 1). For this reason, the speaker apparatus 30 and the illuminating device 10 do not contact directly (especially surface contact). As a result, vibration is less likely to be transmitted. And the illuminating device 10 can be stably suspended from the power supply part 3a of the ceiling 3. FIG. Even if there is a portion where the speaker device 30 and the lighting device 10 are in direct contact, the vibration absorbing member 43b and the vibration absorbing member 42 can absorb a certain amount of vibration. Thereby, the illuminating device 10 can be stably suspended from the power supply part 3a of the ceiling 3. FIG. Moreover, even if either the vibration absorbing member 43b or the vibration absorbing member 42 is omitted, the lighting device 10 can be stably suspended from the power supply unit 3a of the ceiling 3 in the same manner. In addition, it is preferable that the part which the speaker apparatus 30 and the illuminating device 10 contact directly is a part with few areas so that the vibration of the speaker apparatus 30 is not substantially transmitted to the illuminating apparatus 10. FIG.

In this embodiment, the speaker device 30 is fixed to the lighting device 10 with the screw 9a by the above configuration (see FIG. 1). The vibration absorbing member 43b is a washer that is inserted between the speaker device 30 and the lighting device 10 through which the screw 9a is inserted. The predetermined portion (here, the flange 31) that is fastened and fixed by the screw 9a in the speaker device 30 is pressed against the lighting device 10 with a stronger force than the simple contact by tightening the screw 9a. Thereby, the vibration of the speaker device 30 is also easily transmitted by the lighting device 10. Therefore, since the vibration absorbing member 43b is sandwiched between the speaker device 30 and the lighting device 10, the vibration of the speaker device 30 is absorbed by the vibration absorbing member 43b. It is difficult for an extra load generated by vibration to be applied to a fixed portion (for example, a flange portion of the cylindrical member 24) between the lighting device 10 and the hanging portion 20 or the like. According to this configuration in which an extra load caused by vibration is less likely to be applied, the lighting device 10 can be more stably suspended from the power supply unit 3a of the ceiling 3.

Further, in this embodiment, with the above configuration, the vibration absorbing member 43a is provided, through which the screw 9a is inserted and sandwiched between the head of the screw 9a and the speaker device 30 (here, the flange 31) (see FIG. 1). The vibration absorbing member 43 a absorbs the vibration of the speaker device 30. For this reason, the vibration absorbing member 43a makes it difficult for the vibration of the speaker device 30 to be transmitted to the screw 9a. The vibration absorbing member 43a makes the screw 9a difficult to loosen. Furthermore, the screw 9 a is screwed into the screw hole of the lighting device 10. For this reason, if the vibration absorbing member 43a is not provided, the vibration of the speaker device 30 may be transmitted to the screw 9a and further to the illumination device 10. However, in this embodiment, since the vibration absorbing member 43a is provided, the vibration of the speaker device 30 is not easily transmitted to the lighting device 10 via the screw 9a. And it is hard to apply the extra load which arises by vibration to the fixed part (for example, flange part of the cylindrical member 24), etc. of the illuminating device 10 and the suspension part 20. Thereby, the illuminating device 10 can be suspended more stably from the power supply part 3a of the ceiling 3.

Further, in this embodiment, the speaker device 30 has a shape surrounding the hanging portion 20 by the above configuration (see FIG. 1). A vibration absorbing member 44 that absorbs vibrations of the speaker device 30 is interposed between the outer surface of the suspension unit 20 facing the speaker device 30 and the inner surface of the speaker device 30 facing the suspension unit 20. For this reason, the vibration of the speaker device 30 is absorbed by the vibration absorbing member 44. Further, vibration due to the sound output of the speaker device 30 is difficult to be transmitted to the cylindrical member 24 (hanging portion 20). And the fixing | fixed part (For example, the flange part of the cylindrical member 24) of the illuminating device 10 and the suspension part 20, and the attachment location (specifically, the power supply connection part 21 and a power supply) of the suspension part 20 to the power supply part 3a. It is difficult to apply an extra load caused by vibration on the connection portion with the portion 3a. If an extra load caused by vibration is applied, there is an increased possibility that the lighting device 10 and the speaker device 30 and the like are dropped from the power supply unit 3a due to damage to the fixed portion and the mounting location. However, according to the configuration of the present embodiment in which an extra load caused by vibration is difficult to be applied, the lighting device 10 can be stably suspended from the power supply unit 3 a of the ceiling 3.

In particular, in this embodiment, the vibration absorbing member 44 is interposed between the speaker device 30 and the cylindrical member 24 by the above-described configuration, so that vibration is hardly transmitted. For this reason, the illuminating device 10 can be stably suspended from the power supply part 3a of a ceiling. Even if there is a portion where the speaker device 30 and the hanging portion 20 are in direct contact with each other, the vibration absorbing member 44 can absorb a certain amount of vibration. Thereby, the illuminating device 10 can be stably suspended from the power supply part 3a of a ceiling. Note that the direct contact portion is preferably a portion with a small area such that the vibration of the speaker device 30 is not substantially transmitted to the lighting device 10, such as the claw 32 aa and the claw 33 ba.

Moreover, in this embodiment, the suspension part 20 has the attachment member attached to the power supply part 3a of the ceiling 3, and the suspension part main body suspended by the attachment member by the said structure (refer FIG. 1). . Here, the attachment member is the power supply connection portion 21. The hanging part main body is a tubular member 24. The hanging part main body is hollow. Then, on the inner surface that forms the hollow, a first hook portion on which a predetermined portion (here, claw 21b) of the attachment member is hooked and a second hook portion that is higher in rigidity than the first hook portion are suspended. Are arranged side by side along the extending direction (here, upward, ie, the normal direction of the ceiling 3). Here, the first hook portion is the upper flange 23 b of the second cylindrical member 23. The second hook is the upper end flange 22 b of the first tubular member 22. Since the upper end flange 22b is made of metal, the strength is high. And the 2nd hook part is located in the ceiling side rather than the 1st hook part. With such a configuration, even if the cylindrical member 24 to which the lighting device 10 or the like is attached may fall off, the claw 21b is caught by the upper end flange 22b, so that the lighting device 10 or the like does not fall off. Since the upper end flange 22b has higher rigidity than the upper flange 23b, the upper end flange 22b can more reliably prevent the upper end flange 22b from dropping off.

Further, in this embodiment, both the first hook portion and the second hook portion are configured such that a predetermined portion of the mounting member is hooked by the above configuration. Thereby, the attachment position of the hanging part 20 can be close to the ceiling 3 or can be set far away. By doing in this way, the user can adjust the attachment position of the lighting unit 1. In addition, when the length of the power supply unit 3a is short, the illumination unit 1 may be configured to hook the predetermined portion of the attachment member on the second hooking portion. Installation according to length) becomes possible. The upper end flange 22b and the upper flange 23b may be changed as appropriate.

Further, as in the above-described embodiment, the illumination device 10 is suspended by the suspension unit 20 extending upward from the illumination device 10 (see FIG. 1). The speaker device 30 surrounds the hanging portion 20 and is attached to the hanging portion 20, so that the speaker device 30 is positioned between the ceiling 3 and the lighting device 10. For this reason, the speaker apparatus 30 and the illuminating device 10 can be arrange | positioned as a separate body on a ceiling. And the illuminating device 10 can be suspended from the power supply part 3a, without interposing the speaker apparatus 30. FIG. For this reason, it becomes difficult to apply the extra load which arises by a vibration to the connection part of the power supply part 3a and the suspension part 20, and the connection part of the suspension part 20 and the illuminating device 10. FIG. Thereby, the illuminating device 10 can be stably suspended from the power supply part 3a of the ceiling 3. FIG.

Moreover, in the said embodiment, the suspension part 20 is extended upwards from the center of the illuminating device 10, and suspends the illuminating device 10 in the center of the illuminating device 10 (refer FIG. 1). For this reason, the illuminating device 10 can be suspended with good balance. Furthermore, the speaker device 30 has a shape surrounding the hanging portion 20 extending upward from the center of the lighting device 10. For this reason, the speaker device 30 is attached to the suspension unit 20 with a good balance. Furthermore, it becomes difficult to apply an extra load due to the bias of the speaker device 30 to each connection portion. Thereby, the illuminating device 10 can be stably suspended from the power supply part 3a of the ceiling 3. FIG. In addition, the speaker device 30 surrounds the hanging portion 20 so that the speaker device 30 accommodates at least a part of the hanging portion 20 inside (inside the through hole). Here, depending on the shape of the hanging part 20, the speaker device 30 may accommodate the entire hanging part 20 therein. As a result, the illumination unit 1 becomes compact in the vertical direction (the horizontal direction in FIG. 1).

If the speaker device 30 and the lighting device 10 are rotatable with respect to the suspension unit 20, if a force for rotating the speaker device 30 or the lighting device 10 for some reason is applied, the suspension unit 20 also rotates. try to. Furthermore, the suspension unit 20 also tries to rotate due to the vibration of the speaker device 30. In such a case, an extra load is applied to the connection part between the hanging part 20 and the power supply part 3a. For example, when the power supply unit 3a is a hooking ceiling and the power supply connection part 21 of the hanging part 20 is rotated and attached to the power supply part 3a, the hanging part 20 may rotate in a direction away from the power supply part 3a. There is also. For example, when the cylindrical member 24 rotates and the power connection portion 21 also rotates together by frictional force, the hanging portion 20 may rotate in a direction away from the power supply portion 3a. And there exists a possibility that the suspension part 20 (illuminating device 10) may drop | omit. In this embodiment, the speaker device 30 and the lighting device 10 are not rotatable with respect to the hanging portion 20 (particularly the cylindrical member 24). For this reason, the speaker device 30, the lighting device 10, and the hanging part 20 (particularly the cylindrical member 24) rotate integrally. Furthermore, since the rotation suppressing member 41 is provided, the speaker device 30 is difficult to rotate with respect to the ceiling 3. For this reason, even if a rotational force is applied to any one of the lighting device 10, the hanging unit 20, and the speaker device 30, the lighting device 10, the hanging unit 20, and the speaker device 30 as a whole have a ceiling 3. Hard to rotate against. As a result, the suspension part 20 is difficult to rotate or does not rotate with respect to the ceiling 3, so the possibility that the suspension part 20 will drop off is low. Further, the rotation suppression member 41 absorbs vibration of the speaker device 30 and makes it difficult to transmit to the ceiling 3. If the rotation suppression member 41 is not provided and the speaker device 30 is in contact with the ceiling 3, the speaker device 30 may rotate due to a reaction from the ceiling 3 due to this vibration. is there. In this embodiment, since the rotation suppressing member 41 is provided, the possibility that the speaker device 30 rotates is reduced. Furthermore, vibration can be efficiently absorbed by disposing the rotation suppression member 41 between two adjacent speakers 38 (see FIG. 2). Here, the two adjacent speakers 38 are, for example, speakers 38a and 38c, speakers 38b and 38c, and the like.

When supplying power from the power supply unit 3a to both the lighting device 10 and the speaker device 30 via the power supply connection unit 21, the following structure is conceivable in addition to the structure shown in this embodiment. First, a structure is conceivable in which power is first supplied from the power supply connection unit 21 to the lighting device 10 via wiring, and power is supplied from the lighting device 10 to the speaker device 30 via wiring. In addition, a structure in which power is first supplied from the power supply connection unit 21 to the speaker device 30 via wiring, and power is supplied from the speaker device 30 to the lighting device 10 via wiring is also conceivable. However, in these structures, in order to facilitate the handling of the power wiring connecting the lighting device 10 and the speaker device 30 and the signal line L3, the above power wiring and the signal line L3 are provided. , They are collectively passed through the through hole 11b. Therefore, the power wiring and the signal line L3 are arranged close to each other. However, if the power wiring and the signal line L3 are arranged close to each other, there is a possibility that noise generated due to a current flowing through the power wiring or the like is placed on the signal line L3. .

In the present embodiment, a wiring L1 for supplying power from the power supply unit 3a to the lighting device 10 and a wiring L2 for supplying power from the power supply unit 3a to the speaker device 30 are provided by the above configuration. (See FIG. 1). For this reason, the power supply between the illuminating device 10 and the speaker device 30 becomes unnecessary. In addition, it is not necessary to provide the power wiring (wiring L1 and wiring L2) and the signal line L3 close to each other. By doing in this way, the malfunction by noise can be prevented or made difficult to occur. As shown in FIG. 1, the wiring L1 and the wiring L2 for supplying power pass through the suspension unit 20 and are connected to the lighting device 10 and the speaker device 30, respectively, and the signal line L3 is suspended. It does not pass through the part 20. By doing in this way, the above-mentioned problems are solved.

The present invention is not limited to the above embodiment, and various modifications can be made to the above embodiment. Examples thereof are shown below, but at least a part of each of the following modifications can be combined as appropriate.

(Modification 1)
The lighting unit 1 may be attached to another part in addition to the power supply unit 3 a of the ceiling 3. The attachment target of the illumination unit 1 may be, for example, a predetermined portion at an upper position that is above the illumination unit 1. Note that the lighting unit 1 is usually attached to a power source unit of a commercial power source in order to supply power to the lighting device 10.

(Modification 2)
The method of supplying power by the power supply connection unit 21 is not limited to the above. For example, the power supply connection unit 21 supplies power to the speaker device 30 and the lighting device 10 as they are without converting the power supplied from the power supply unit 3a. There may be. The wiring L1, the wiring L2, and the signal line L3 may also have appropriate shapes and configurations.

(Modification 3)
The shape and configuration of the illumination device 10 are not limited to the above, and an appropriate shape and configuration may be adopted. For example, in the above embodiment, the illumination device 10 is circular when viewed from below, but may be rectangular or the like. The light emitting unit 13 may be a fluorescent tube, organic EL lighting, or the like.

(Modification 4)
The shape and configuration of the hanging part 20 are not limited to the above, and an appropriate shape and configuration may be adopted. For example, the hanging unit 20 may suspend the lighting device 10 so that the speaker device 30 can be positioned on the lighting device 10. The hanging part 20 may have a configuration in which, for example, the power connection part 21 and the first tubular member 22 are integrated. Further, at least a part of the hanging portion 20 (for example, the cylindrical member 24) may be formed integrally with the lighting device 10 (the lighting top plate 11). The hanging part 20 may have a configuration that extends upward (in the direction toward the ceiling 3) from the upper surface of the lighting device 10 as in the above embodiment. In addition, the illuminating device 10 may have a configuration that extends upward from the inside of the illuminating device 10, for example, through a central through hole of the illumination top plate 11.

(Modification 5)
The shape and configuration of the speaker device 30 is not limited to the above, and an appropriate shape and configuration may be adopted. The speaker device 30 may be operated by an internal power source such as a battery. Further, for example, the speaker device 30 may include a storage unit that stores sound source data. The speaker device 30 may output sound by reproducing sound source data stored in the storage unit in response to a signal from a remote controller, for example.

(Modification 6)
The shape of the speaker device 30 may be, for example, a shape surrounding the hanging portion 20 and is not limited to a substantially cylindrical shape. For example, the cross section when cut in the horizontal direction may be a polygonal shape such as a triangular shape or a quadrangular shape and a cylindrical shape having a predetermined thickness. Further, the speaker device 30 has, for example, a shape surrounding the hanging portion 20, and a portion surrounding the hanging portion 20 with a gap, for example, in addition to a shape surrounding the hanging portion 20 continuously 360 degrees. It may be a thing. The gap in this case is preferably set to a width that prevents the hanging portion 20 from coming out of the gap when the speaker device 30 moves in the horizontal direction. The hanging part 20 may not have a shape surrounding the hanging part 20 as long as it is arranged between the ceiling 3 and the lighting device 10.

(Modification 7)
The shape, attachment position, and the like of the vibration absorbing members 42, 43a, 43b, 44 and the rotation suppressing member 41 may be changed as appropriate. For example, the vibration absorbing member 42 may have an arc shape or an annular shape. Moreover, the vibration absorption member 43a should just be pinched | interposed between the flange 31 and the head of the screw 9a, and does not need to be a donut shape like a washer. For example, the vibration absorbing member 43a may have a C shape, a rectangular parallelepiped shape, or a semi-annular shape, and may be disposed around a portion other than the head of the screw 9a. The vibration absorbing member 43b may be any member as long as it is sandwiched between the flange 31 and the lighting device 10 so that the flange 31 does not substantially contact the lighting device 10, and does not have a donut shape such as a washer. Good. Here, substantially not contacting means not making contact that transmits vibration. The vibration absorbing member 43a has, for example, a C shape, a rectangular parallelepiped shape, or a semi-annular shape, and may be disposed around a portion other than the head of the screw 9a. The position of the vibration absorbing member 44 may be arranged at a position away from the recesses 32a and 32b. In the above embodiment, the diameter of the inner surface of the speaker device 30 is longer than the diameter of the cylindrical member 24. For this reason, even if the vibration absorbing member 44 is not provided, the inner surface of the speaker device 30 and the tubular member 24 do not contact each other. For this reason, the vibration absorbing member 44 is not an essential configuration. The shape of the rotation suppressing member 41 may also be an arc shape, an annular shape, or the like. Further, the first member 41a and the second member 41b may not have the same shape.

(Modification 8)
The speaker device 30 may be fixed to the lighting device 10 via a vibration absorbing member that absorbs vibration generated by sound output, for example. For example, the vibration absorbing member 42 and the speaker device 30, and the vibration absorbing member 42 and the lighting device 10 are fixed to each other with a double-sided tape, an adhesive (including an adhesive), or the like, so that the speaker device 30 is attached to the lighting device 10. It may be fixed. In this case, the flange 31, the screw 9a, and the vibration absorbing members 43a and 43b may be omitted. Further, the flange 31 may be fixed by other fixing means for tightening the lighting device 10. Here, the other fixing means is, for example, a nail. The screw also includes a bolt used with a nut. In this way, fastening and fastening (tightening and fixing) means fixing by a force applied along at least one of the vertical directions (such as the thickness direction of the flange 31 and the like). The speaker device 30 should just be arrange | positioned on the illuminating device 10 (ceiling side). For example, the speaker device 30 is merely placed on the lighting device 10 via a vibration absorbing member that absorbs vibration generated by sound output, and may not be fixed. Further, the portion to be tightened may be a predetermined portion of the speaker device 30, and may not be a flange like the flange 31. For example, a concave portion may be provided on the outer surface of the speaker device 30, and a plate-like member into which a screw 9a or the like is inserted may be provided at the lower portion, and fastening and fixing may be performed at this portion. Further, any one of the vibration absorbing members 42, 43a, 43b may be omitted.

(Modification 9)
The power supply connection part 21 should just be an attachment member attached to the attachment object of the illumination unit 1, and another thing may be sufficient as it. Moreover, the cylindrical member 24 should just be a suspending part main body suspended by the attachment member. The first hook part and the second hook part are provided on the inner surfaces of the first cylindrical member 22 and the second cylindrical member 23 (or the cylindrical member 24), in addition to those constituted by flanges. It may be a recess or the like. In such a case, in order to prevent the cylindrical member 24 from rotating with respect to the power supply connection portion 21, the shape of the concave portion is set at a portion hooked to the first hook portion and the second hook portion in the attachment member such as the claw 21b. You may make it match | combine with the shape of a certain predetermined part.

(Modification 10)
In said embodiment, the 1st cylindrical member 22 has one flange (upper end flange 22b). The second cylindrical member 23 also has one flange (upper flange 23b). Without being limited thereto, the first tubular member 22 may have a plurality of flanges along the normal direction of the ceiling 3. The second cylindrical member 23 may also have a plurality of flanges along the normal direction of the ceiling 3. By doing in this way, the cylindrical member 24 can be attached to the suspension part 20 at three or more different positions along the normal direction of the ceiling 3. Further, it is assumed that the claw 21b is caught on the lower surface of the flange, which is farthest from the ceiling 3. At this time, it is assumed that the cylindrical member 24 is further dropped when the cylindrical member 24 is dropped and the claw 21b is caught by another flange. In this case, the claw 21b is caught on another flange. As a result, the cylindrical member 24 can be more reliably prevented from falling off. Moreover, since the user can attach the cylindrical member 24 in three or more different positions, the attachment position of the illumination unit 1 can be adjusted more precisely.
