Therefore, in order to prevent the antenna pattern from being damaged during transportation, the antenna pattern must be protected by a protective member or the like. This results in an increase in unnecessary costs when assembling the parts.

  For this reason, this indication aims at providing a lighting installation which can control a rise of manufacturing cost concerning attachment of a lighting installation.

  In order to achieve the above object, one aspect of a lighting device according to the present invention holds a second substrate supported in a standing state with respect to a first substrate, and holds the first substrate, and And a mounting support portion having a storage space into which the second substrate is inserted, wherein the storage support portion is associated with the second substrate. By fitting, it has an engagement recess which supports the second substrate in a predetermined posture.

  According to the present disclosure, it is possible to suppress the increase in manufacturing cost for assembling the lighting device.

[Operation]
The lighting device 1 executes lighting and sound output desired by the user based on the wireless signal for the lighting unit 20 and the wireless signal for the acoustic unit 40 transmitted from the operation terminal. At the time of reception, the wireless signal for the illumination unit 20 and the wireless signal for the acoustic unit 40 may interfere with each other. However, as described above, since the first wireless module 46 and the second wireless module 47 are disposed as far apart as possible in the first accommodation unit 251, the wireless signal for the illumination unit 20 and the acoustic unit 40 are provided. In the case of simultaneously receiving a wireless signal for communication, mutual wireless signals are less likely to interfere with each other.

  Next, the operation at the time of lighting in the lighting device 1 will be described.

  The illumination control unit 13 controls the first light source 121 and the second light source 122 based on the wireless signal for the illumination unit 20 received by the first wireless module 46. Light emitted from the plurality of first light sources 121 is subjected to light distribution control by the lens of the lens cover 23, passes through the light transmission cover 7, and travels in the Z-axis direction of the illumination device 1. In addition, light emitted from the plurality of second light sources 122 in the Y-axis positive direction side and the Y-axis negative direction side is incident on the incident surface of each of the first light guide plate 3 and the second light guide plate 4 to be curved portion 31 and The flat plate portion 35 is guided. In the curved portion 31, the light reflected by the first light blocking member 5 and the second light blocking member 6 enters even if the light is reflected by the outer surface of the curved portion 31 or emitted from the outer surface. A part of the light guided through the flat plate portion 35 is reflected by the prism surface 35 a, travels to the emission surface 35 b, and is emitted from the emission surface 35 b. Thus, in the lighting device 1, the surrounding can be illuminated by emitting illumination light from each of the light transmitting cover 7, the first light guide plate 3 and the second light guide plate 4.

  Next, the operation at the time of sound output in the lighting device 1 will be described.

  The sound control unit 16 controls the speaker 41 based on the wireless signal for the sound unit 40 received by the second wireless module 47. A sound based on sound data is output from the pair of speakers 41. At the time of output of sound, the vibration caused by the sound is generated from the pair of speakers 41. This vibration is also transmitted to the illumination unit 20. For example, when the vibration from the pair of speakers 41 is transmitted in a biased manner with respect to the illumination unit 20, the illumination unit 20 also largely vibrates, and the illumination light also largely shakes. However, in the present embodiment, since the center of gravity of the pair of speakers 41 is disposed in the first opening 20 a when the first opening 20 a is viewed in plan, illumination from each of the pair of speakers 41 is The vibration is transmitted to the portion 20 substantially uniformly. As a result, the illumination unit 20 is relatively hard to swing, and illumination light with small swing can be obtained. In particular, in the present embodiment, the center of gravity of the entire lighting apparatus 1 is disposed in the first opening 20a when the first opening 20a is viewed in plan, so the entire lighting apparatus 1 can be made of a construction material in a well-balanced manner. It is installed and has a support structure that resists shaking. For this reason, the vibration caused by the sound from the speaker 41 is less likely to be affected by the illumination unit 20.

Further, the second mounting plate 264 has a housing support portion 265 having a housing space 265a into which the second wireless module 47 is inserted. And the accommodation support part 265 has the engagement recessed part 269 which supports the 2nd radio | wireless module 47 in a predetermined | prescribed attitude | position by engaging with the 2nd radio | wireless module 47. As shown in FIG.

  Thus, the second attachment plate 264 holds the second circuit board 270 and holds the second wireless module 47 detachably. The second mounting plate 264 has a housing support portion 265 having a housing space 265 a into which the second wireless module 47 is inserted. The housing support portion 265 is formed with an engagement recess 269 engaged with the second wireless module 47, and supports the second wireless module 47 in a predetermined posture.
