The lighting circuit 54 may be formed by a plurality of circuit components arranged on a substrate separate from the substrate 25, and may be housed in a housing separate from the lighting device 10. Further, the lighting circuit 54 may use the wireless communication unit 35 to exchange control signals and the like with the terminal device. That is, the wireless communication unit 35 may be shared by the speaker device 30 and the light emitting unit 50.

In FIG. 5, the speaker driving circuit 34 and the lighting circuit 54 are illustrated separately. However, these circuits do not have to be completely separated, and these two circuits have functions of the two circuits. The lighting device 10 may be provided as a single control circuit.

In the present embodiment, the light guide plate 55 is an optical member formed of a material having relatively high translucency, such as resin or glass. In the present embodiment, the light guide plate 55 has such transparency that the speaker case 31 and the front panel 32 of the speaker device 30 are visible from the outside of the illumination device 10 via the light guide plate 55. The light guide plate 55 can also have light diffusibility, for example, by containing a light diffusing material or by surface treatment such as embossing.

The light guide plate 55 according to the present embodiment has a shape that follows the outer shape of the speaker device 30 when viewed from the front, as shown in FIG. That is, the light guide plate 55 has an annular shape along the outer shape of the circular speaker device 30. In addition, a plurality of light emitting elements 52 are disposed at positions facing the rear end face (end face on the Z-axis minus side) of the light guide plate 55, and the front end portion (end portion on the Z-axis plus side) of the light guide plate 55 is In the front-rear direction (Z-axis direction), it is located in front of the speaker device 30. That is, the light guide plate 55 can guide and emit light from the light source unit 51 located behind the front surface of the speaker device 30 (front surface of the front panel 32) to the front of the speaker device 30. .

In short, the end face 56 of the light guide plate 55 has a shape cut obliquely. Thereby, for example, light distribution control of light emitted from the light guide plate 55 is performed. In FIG. 5, only a part of the end surface 56 of the light guide plate 55 is inclined with respect to the front-rear direction, but the entire end surface 56 may be formed inclined with respect to the front-rear direction.

[2. Effect etc.]
As described above, the illuminating device 10 according to the present embodiment is an illuminating device 10 that emits illuminating light forward, and is detachably attached to an external socket 80 and receives power from the socket 80. Unit 21, speaker device 30 that is a functional unit that executes a predetermined operation using power supplied from power receiving unit 21, and light emitting unit 50. The light emitting unit 50 is disposed so as to surround the speaker device 30 along the outer shape of the speaker device 30 when viewed from the front, and emits illumination light using the power supplied from the power receiving unit 21. The front end portion of the light emitting unit 50 is located in front of the speaker device 30 in the front-rear direction.

According to this configuration, when the illuminating device 10 is viewed from the front, the speaker device 30 and the light emitting unit 50 are arranged at positions adjacent in the horizontal direction. Thereby, compared with the case where a light emission part and the speaker apparatus 30 are arranged in the front-back direction, the thickness of the illuminating device 10 can be made thin, for example. Further, when viewed from the front, even if the emission portion of the illumination light in the light emitting unit 50 and the speaker device 30 are side by side, the front end portion of the emission portion is located in front of the speaker device 30, The illumination light emitted from the light emitting unit 50 is not obstructed by the speaker device 30. Furthermore, since the light emitting unit 50 is disposed so as to surround the speaker device 30, for example, when the lighting device 10 attached to the ceiling is looked up, the possibility that the speaker device 30 having no light emitting function looks dark is reduced. Is done. That is, it is difficult to form a dark part in the illumination device 10 in appearance.

Thus, according to the illumination device 10 according to the present embodiment, the speaker device 30 as a functional unit that executes a predetermined operation is provided, and the size can be reduced.

Moreover, in the illumination device 10 according to the present embodiment, when viewed from the front, the speaker device 30 is circular, and the light emitting unit 50 is annular.

That is, the illuminating device 10 has a structure in which the circular speaker device 30 is provided at the center of the annular light emitting unit 50 when viewed from the emission direction of the illumination light. Therefore, for example, when the lighting device 10 is attached to the socket 80, the lighting device 10 can be attached without worrying about the rotational position around the Z axis. In other words, even when the illumination device 10 is rotated around the Z axis, the appearance of the illumination device 10 is substantially the same as the state before the rotation. Further, since the illumination light is emitted radially from the annular light emitting unit 50, the emission range of the illumination light is almost the same as the emission range before the rotation even when the illumination device 10 is rotated around the Z axis. Are the same. Therefore, for example, the lighting device 10 can be mounted without changing the illumination light emission range regardless of the rotational position of the pair of power supply holes 82 in the socket 80. That is, it can be said that the lighting apparatus 10 according to the present embodiment can be downsized and has a wide selection range of sockets to be attached.

Moreover, in the illuminating device 10 which concerns on this Embodiment, the light emission part 50 has the light guide plate 55 of the shape in alignment with the external shape of the speaker apparatus 30, and the some light emitting element arrange | positioned facing the back end surface of the light guide plate 55. 52.

As described above, in the present embodiment, the light from the plurality of light emitting elements 52 is guided forward from the speaker device 30 by the light guide plate 55. Thus, for example, by adjusting the length of the light guide plate 55 in the front-rear direction, the light emitting unit 50 that emits appropriate illumination light according to the thickness of the speaker device 30 (width in the Z-axis direction) is configured. be able to. Moreover, since the several light emitting element 52 will be arrange | positioned in the outer peripheral part in the illuminating device 10, the heat radiation of each of the several light emitting element 52 can be performed efficiently, for example. Therefore, a decrease in luminous efficiency due to heat when the LED element is employed as the light emitting element 52 as in the present embodiment is suppressed.

Further, in the illumination device 10 according to the present embodiment, at least a part of the end surface 56 at the front end portion of the light guide plate 55 that is the front end portion of the light emitting unit 50 is formed to be inclined with respect to the front-rear direction.

In this way, by inclining at least a part of the end face 56 closest to the irradiation target of the illumination light (that is, the foremost end face) 56 in the light guide plate 55, for example, the distribution of the illumination light emitted from the light guide plate 55. The light angle can be controlled efficiently. As a result, for example, the possibility that the front end portion of the light guide plate 55 looks dazzling is reduced.

In addition, the aspect of the light emission part and function part in the illuminating device 10 is not limited to the aspect demonstrated by the said embodiment. Therefore, hereinafter, modifications of the light emitting unit and the functional unit in the lighting device 10 will be described focusing on differences from the above embodiment.

(Modification 1)
FIG. 6 is a cross-sectional view illustrating a schematic configuration of an illuminating device 10a according to Modification 1 of the embodiment. The cross-sectional position in FIG. 6 conforms to the cross-sectional position of the illumination device 10 in FIG. 5 described above, and the lighting circuit 54 is not shown. These matters are the same in FIGS. 7 to 9 described later. In FIG. 6, the speaker device 30 is schematically represented by a hatched rectangle.

The illuminating device 10a shown in FIG. 6 includes a speaker device 30 as a functional unit and a light emitting unit 50. The light emitting unit 50 is disposed so as to surround the speaker device 30 when viewed from the front (Z-axis plus direction). In this regard, the lighting device 10a according to the present modification is common to the lighting device 10 according to the above-described embodiment.

In this modification, the light guide plate 55a included in the light emitting unit 50 is connected to the curved portion 55b that extends outward as it goes forward, and the front surface portion 55c that is connected to the curved portion 55b and forms a light emitting surface that extends in a direction intersecting the front-rear direction. And have. In this configuration, the illumination device 10a according to the present modification is different from the illumination device 10 according to the above embodiment. More specifically, the light guide plate 55a according to the present modification includes a front surface portion 55c that forms a light emitting surface extending in a direction orthogonal to the front-rear direction (a direction parallel to the XY plane).

According to this configuration, since the light emitting unit 50 can emit illumination light from a light emitting surface that is a relatively wide surface, the illumination device 10a is, for example, main illumination (for example, “ceiling light”) in a living room. Can be used as

For example, a fine uneven structure is formed on the front surface portion 55c of the light guide plate 55a on the surface opposite to the light emitting surface (Z-axis minus side) so that light is efficiently emitted from the light emitting surface. Alternatively, a reflection film that reflects light may be disposed.

(Modification 2)
FIG. 7: is sectional drawing which shows the structure outline | summary of the illuminating device 10b which concerns on the modification 2 of embodiment. The sensor device 60 and its constituent elements are schematically represented by dotted lines.

The illuminating device 10b shown in FIG. 7 includes a sensor device 60 as a functional unit that performs a predetermined operation using the electric power supplied from the power receiving unit 21, and in this respect, the illuminating device 10b according to the above-described embodiment and Different.

The sensor device 60 includes a sensor case 61, a sensor 62 that detects the surrounding situation, a sensor control unit 64 that controls the sensor 62, and a wireless communication unit 65. Examples of the sensor 62 include an infrared sensor, an image sensor, and a millimeter wave sensor that detect an object such as a person, and a temperature sensor, a humidity sensor, and an illuminance sensor that detect values related to the surrounding environment.

The sensor device 60 configured as described above performs, for example, the following operation. The wireless communication unit 65 receives a control signal transmitted from an external device such as a dedicated remote controller or a smartphone. The sensor control unit 64 controls the operation of the sensor 62 according to the control signal, and transmits the detection result by the sensor 62 to an external device via the wireless communication unit 65. Thereby, for example, an external device can acquire information such as the presence or absence of a person in the space where the lighting device 10b is arranged, or the temperature or brightness of the space.

Further, the light emitting unit 50 can perform a light emitting operation according to the detection result obtained by the sensor 62 acquired from the sensor control unit 64. For example, when the detection result by the sensor 62 that is an infrared sensor indicates that a person is present, the light emitting unit 50 causes the light source unit 51 to emit light. Thereafter, when the detection result by the sensor 62 indicates that no person is present, the light emitting unit 50 stops the light emission of the light source unit 51.

The lighting device 10b according to the present modification can thus notify the external device of the detection result of the sensor device 60. Further, the illumination device 10b can perform a light emitting operation according to the detection result by the sensor device 60.

Moreover, in the illuminating device 10b which concerns on this modification, since the front-end part of the light emission part 50 is located ahead of the sensor apparatus 60, the illumination light radiate | emitted from the light emission part 50 may be prevented by the sensor apparatus 60. FIG. Absent. Further, when viewed from the front, the sensor 62 is disposed in the central portion of the lighting device 10 b, so that, for example, the light emitting unit 50 (more specifically, the light guide plate 55) around the sensor device 60 is connected to the sensor 62. The influence on the detection range can be suppressed. Furthermore, since the light emitting unit 50 is disposed so as to surround the sensor device 60, for example, when looking up the lighting device 10 attached to the ceiling, the possibility that the sensor device 60 having no light emitting function looks dark is reduced. Is done.

(Modification 3)
FIG. 8 is a cross-sectional view illustrating a schematic configuration of a lighting apparatus 10c according to the third modification of the embodiment. The ion generator 70 and its components are schematically represented by dotted lines.

The illuminating device 10c shown in FIG. 8 includes an ion generator 70 as a functional unit that performs a predetermined operation using the power supplied from the power receiving unit 21, and in this respect, the illuminating device 10 according to the above embodiment. And different.

The ion generator 70 includes an ion generator case 71, an ion generation unit 72 that generates ions by applying a high voltage to moisture in the air, and a generation control unit 74 that controls the ion generation unit 72.

The ion generator 70 configured as described above performs, for example, the following operation. When power supply from the power receiving unit 21 is started, the generation control unit 74 starts generating ions by operating the ion generation unit 72. Ions generated by the ion generator 72 are released into the space where the illumination device 10c is arranged. The operation for generating and releasing ions by the ion generator 70 may be performed in synchronization with the light emission operation of the light emitting unit 50, or may be performed asynchronously with the light emission operation of the light emitting unit 50. Good. For example, the operation of the ion generator 70 may be controlled by a control signal transmitted from an external device such as a dedicated remote controller or a smartphone.

The illumination device 10c according to the present modification can thus emit ions generated in the ion generator 70 to the space in which the illumination device 10c is arranged, and thus, for example, air in the space The environment can be improved.

Moreover, in the illuminating device 10c which concerns on this modification, since the front-end part of the light emission part 50 is located ahead of the ion generator 70, the illumination light radiate | emitted from the light emission part 50 is obstructed by the ion generator 70. FIG. There is nothing. In addition, when viewed from the front, the ion emission position is arranged in the central portion of the illumination device 10c, so that, for example, the light emitting unit 50 (more specifically, the light guide plate 55) around the ion generator 70 is ionized. The influence on the release range of can be suppressed. Furthermore, since the light emitting unit 50 is disposed so as to surround the ion generator 70, for example, when looking up the illumination device 10c attached to the ceiling, the ion generator 70 having no light emitting function may appear dark. Is reduced.

(Modification 4)
FIG. 9 is a partial cross-sectional view illustrating a schematic configuration of an illumination device 10d according to Modification 4 of the embodiment. In FIG. 9, the main body 120 is illustrated in a cross-section only in a portion close to the speaker device 30 and the light emitting unit 150, and a portion close to the power receiving unit 121 is illustrated in a side view.

The illuminating device 10d shown in FIG. 9 includes a speaker device 30 as a functional unit and a light emitting unit 150. The light emitting unit 150 is disposed so as to surround the speaker device 30 when viewed from the front (Z-axis plus direction). In this regard, the lighting device 10d according to the present modification is common to the lighting device 10 according to the above-described embodiment.

In the present modification, the light emitting unit 150 includes a light source unit 51 including a plurality of light emitting elements 52 and a light source cover 155 that covers the light source unit 51. Specifically, the light emitting unit 150 includes a light source cover 155 having a shape that follows the outer shape of the speaker device 30 and a plurality of light emitting elements 52 covered by the light source cover 155. The light source cover 155 has a front surface portion 156 that forms the front end portion of the light emitting portion 150. The front surface portion 156 is disposed away from the plurality of light emitting elements 52 and transmits light from the plurality of light emitting elements 52.

As described above, in this modification, the light source cover 155 that forms a light passage space in front of the light emitting element 52 instead of the light guide plate is employed as a member that emits light from the light emitting element 52 as illumination light. . The light source cover 155 is, for example, a milky white translucent cover formed of a resin material in which light diffusion particles are dispersed, and can diffuse and emit light emitted from the light emitting element 52. More specifically, light that has been reflected at least once within the light source cover 155 is incident on the front surface portion 156 in addition to light that is directed directly from the light emitting element 52. The light incident on the front portion 156 is diffused and emitted from the front portion 156. Thereby, illumination light is emitted from the light emitting unit 150 toward the front. Even in this case, since the speaker device 30 and the light emitting unit 150 are arranged at positions adjacent to each other in the horizontal direction, the thickness of the illumination device 10d is larger than that in the case where the light emitting unit and the speaker device 30 are arranged in the front-rear direction. Can be made thinner. Further, since the illumination light emitted from the light emitting unit 150 is not hindered by the speaker device 30 and the light emitting unit 150 is disposed so as to surround the speaker device 30, the speaker device 30 having no light emitting function is provided. The possibility of looking dark is reduced. That is, it is difficult to form a dark part in the illumination device 10d in appearance. Thus, according to the illuminating device 10d which concerns on this modification, the speaker apparatus 30 as a function part which performs a predetermined | prescribed operation | movement is provided, and size reduction is possible.

Note that it is not essential that the light source cover 155 be formed of a resin material in which light diffusion particles are dispersed. For example, the light diffusion function may be realized by forming a milky white light diffusion film or minute unevenness on the inner surface or the outer surface of the light source cover 155. In addition, it is not essential that the light source cover 155 has a light diffusing function. For example, the light source cover 155 may be formed of glass or resin having visible light transmittance that is recognized as transparent in appearance.

In this modification, a screw base such as an E26 base is employed as the power receiving unit 121. Thereby, for example, the lighting device 10d can be attached to a power supply device (socket) provided in a table lamp or a table lamp, as well as a power supply device fixed to a ceiling or the like. Note that the lighting device 10d may include a power receiving unit having a pair of lamp pins, such as the power receiving unit 21 according to the embodiment, instead of the screw cap.

In the present modification, the light source cover 155 is a side wall portion 157 that forms a side wall opposite to the speaker device 30, and reflects at least part of the light from the plurality of light emitting elements 52 to the front surface portion 156. Side wall portion 157 leading to Specifically, in this modification, the side wall part 157 is a part provided integrally with the front surface part 156, and is formed of, for example, a resin material in which light diffusion particles are dispersed. Therefore, the side wall portion 157 can transmit at least part of the light from the plurality of light emitting elements 52.

Thereby, the light source cover 155 can efficiently emit the light from the plurality of light emitting elements 52 included in the light emitting unit 150 forward from the front surface portion 156 and also from the side wall portion 157 toward the side. Therefore, as described above, for example, when the lighting device 10d is attached to the socket of the desk lamp, the lighting device 10d can emit light toward the shade of the desk lamp. Thereby, it is possible to obtain a light effect by reflecting or transmitting light in the shade.

In addition, the light source cover 155 according to the present modification includes an inner wall portion 158 provided integrally with the front surface portion 156 and the side wall portion 157. The inner wall portion 158 is a portion that forms the side wall of the light source cover 155 on the speaker device 30 side. In the present modification, like the side wall portion 157, at least part of light from the plurality of light emitting elements 52 can be transmitted. In addition, at least part of the light from the plurality of light emitting elements 52 can be reflected and guided to the front surface portion 156. When it is not necessary to emit light from the inner wall portion 158 to the speaker device 30 side, for example, the inner surface of the inner wall portion 158 is white to increase the amount of light emitted from the front surface portion 156 and the side wall portion 157. It is also possible.

Further, in the light source cover 155, it is not essential that the front surface portion 156, the side wall portion 157, and the inner wall portion 158 are integrally provided, and the light source cover 155 may be formed by a combination of different members.

In the present modification, the illumination device 10d includes the speaker device 30 as a functional unit. However, the illumination device 10d may include other types of functional units such as the sensor device 60 and the ion generator 70. Good.

Further, the light emitting element 52 may be an LED chip itself, not an SMD type LED element. That is, the light emitting unit 50 has, for example, a COB (Chip On Board) structure in which a plurality of light emitting elements 52 (LED chips) directly mounted on the substrate 25 are sealed with a translucent resin material containing phosphor particles. You may have.

Further, the light emitting element 52 included in the light emitting unit 50 is not limited to an LED chip or an element using the LED chip.
