As a result, it is possible to transmit light information, sound information, and the like held by the lighting device 10 to other adjacent lighting devices. Conversely, it becomes possible to receive light information, sound information, and the like transmitted from other adjacent lighting devices. As a result, when there are a plurality of lighting devices 10 in a certain space, they can be adjusted to have the same color and the same music, or they can emit light in different colors to adjust the overall color balance. , volume, amount of light, type of sound, different colors, etc. can be adjusted. The adjustment of sound and light based on the sound information and light information of the plurality of lighting devices 10 is preferably performed by the controller 15 of each lighting device 10, for example.

Note that the plurality of lighting devices may include a first lighting device and a second lighting device. At this time, the first lighting device receives at least one of the fourth light information and the fourth sound information of the second lighting device from the second lighting device. The control unit of the first lighting device interlocks the dimmer and the sound adjuster of the first lighting device based on at least one of the fourth light information and the fourth sound information of the second lighting device. may be controlled.

The plurality of lighting devices may further have a third lighting device. At this time, the first lighting device transmits at least one of the fourth light information and the fourth sound information of the second lighting device to the third lighting device. Then, the first lighting device may transmit at least one of the dimming state of the dimmer of the first lighting device and the articulation state of the articulator of the first lighting device to the third lighting device. .

Note that, in the present disclosure, the light information may include information indicating the light itself and dimming information. For example, it is the ON/OFF state of light, the illuminance of light, color temperature, spectrum information, and the like. The dimming information is information about light for adjusting the light emitting device 1, and even if it is information indicating the light itself that should be emitted from the light emitting device 1, the light emitting device 1 is currently emitting light. It may be change instruction information for light. For example, it may be the ON/OFF state of the light, the illuminance of the light, the color temperature, the spectrum information itself, or the information indicating the increase/decrease of the illuminance of the light or the color temperature.

Furthermore, in the present disclosure, the sound information may include information indicating the sound itself and articulatory information. For example, it is information indicating volume and type of music. The articulatory information is information about the sound for adjusting the speaker 13, and even if it is information indicating the sound itself that should be emitted from the speaker 13, it is change instruction information for the sound that the speaker 13 is currently emitting. There may be. For example, information indicating the volume or the type of music itself, or information indicating the increase/decrease of the volume may be used.

Note that the present disclosure is not limited to the examples of the embodiments described above, and various modifications such as numerical values are possible. Various combinations of features in this embodiment are not limited to the examples of the embodiments described above.
