The decorative board 42 covers the one or more acoustic sections 50 and the second support 12 and is supported by the one or more acoustic sections 50 and the second support 12 .

According to this, since the main cover 41 has translucency, the light emitted by the light emitting module 20 can be emitted. Moreover, since one or more acoustic parts 50 can be arranged between the decorative board 42 and the second support body 12, it is possible to suppress the lighting device 1 from increasing in size. Further, the appearance of the lighting device 1 can be improved by the main cover 41 through which light is emitted and the decorative plate 42 arranged around the main cover 41.

Further, in the lighting device 1 according to the present embodiment, one or more acoustic parts 50 are supported by the decorative board 42 or the second support body 12.

According to this, since one or more acoustic parts 50 can be supported in a desired posture, it is possible to suppress misalignment of one or more acoustic parts 50 with respect to the decorative board 42.

Further, for example, when one or more acoustic sections 50 are supported by the decorative board 42, the one or more acoustic sections 50 can be brought close to the plurality of sound holes 43a. Therefore, deterioration of the sound quality and sound pressure of the sound output from the lighting device 1 can be suppressed.

Therefore, since shadows are less likely to be reflected in the light emitted from the diffusion cover 40, the illumination device 1 can emit more uniform light.

Moreover, since the communication unit can wirelessly communicate with the external device 90 through the opening, it is possible to ensure the radio field strength with the external device 90 and to improve the wireless reach.

Furthermore, in the lighting device 1 according to the present embodiment, a plurality of light emitting modules 20 are provided. The communication unit is arranged between two adjacent light emitting modules 20.

Therefore, increasing the diameter of the lighting device 1 can be suppressed.

Further, communication performance can be ensured better than when the light emitting module 20 is placed at a corner of the lighting device 1, and the light emitted from the light emitting module 20 can be made less likely to be blocked. That is, in this lighting device 1, it is possible to ensure the communication performance of the lighting device 1 and to suppress uneven brightness of the light emitted from the diffusion cover 40.

Therefore, the acoustic communication section 71 and the lighting communication section 72 can suppress the influence of the magnetic field caused by the pair of acoustic sections 50, so that communication performance can be ensured.

Furthermore, if the acoustic communication section 71 and the lighting communication section 72 are placed as far apart as possible, the acoustic wireless signal received by the acoustic communication section 71 and the lighting wireless signal received by the lighting communication section 72 can be separated. Since interference can be suppressed, the acoustic communication section 71 and the lighting communication section 72 and the external device 90 can communicate more reliably.

Furthermore, in the lighting device 1 according to the present embodiment, the housing 10 is provided with a pair of acoustic sections 50. Further, the lighting device 1 includes an acoustic power supply unit 61 that supplies power to drive the pair of acoustic units 50, and a lighting power supply unit 62 that supplies power to light the light emitting module 20.
