Next, the control circuit 705 determines whether or not the switch of the lamp 602 is OFF based on the ON / OFF input of the turn-off instruction input from the power line 310 via the communication control circuit 702 (step S816). If it is determined in step S813 that the audio output switch is not ON (step S813: No), the process proceeds to step S816.

  If it is determined that the switch of the lamp 602 is not OFF (step S816: No), the process proceeds to step S812, and the processes of steps S812 to S816 are repeated. When it is determined that the switch of the lamp 602 is OFF (step S816: Yes), the control circuit 705 operates the relay SW 708 or the switch 711 to turn off the lamp 602 (step S817).

  Then, the control circuit 705 determines whether the voice output switch is OFF based on the ON / OFF input of the voice output stop instruction input from the power line 310 via the communication control circuit 702 (step S818). . If it is determined in step S811 that the switch of the lamp 602 is not ON (step S811: No), the process proceeds to step S818.

  If it is determined that the sound output switch is not OFF (step S818: No), the process proceeds to step S814, and the processes of steps S814 to S818 are repeated. If it is determined that the audio output switch is OFF (step S818: Yes), the control circuit 705 controls the power supply circuit 706 or operates the switch 712 to stop the power supply to the signal processing circuit 704, for example. At the same time, the audio output from the speaker 601 is stopped (step S819), and the process returns to the determination process of step S811 to loop the operation process.

It is determined whether or not the voice output switch is OFF (step S1220). In step S1213, when it is determined that the switch of the lamp 602 of the lighting apparatus 100 is not ON (step S1213: No), the process proceeds to step S1220.

  When it is determined that the sound output switch of the lighting apparatus 100 is not OFF (step S1220: No), the process proceeds to step S1216, and the processes of steps S1216 to S1220 are repeated. When it is determined that the sound output switch of the lighting apparatus 100 is OFF (step S1220: Yes), the control circuit 705 of the lighting apparatus 100 supplies power to the signal processing circuit 704 by the power supply circuit 706 (or switch 712). The supply is stopped and the sound output from the speaker 601 is stopped (step S1221), and the process returns to the determination process of step S1213 to loop the operation process.

  In the lighting system described above, a sound signal output by the lighting device 100 is transmitted from the sound supply device 1000 to the lighting device 100 by PLC, wireless communication, or the like. However, the sound signal is stored in the card slot 505a. Those recorded on an external recording medium or the like may be used. In the lighting system described above, the audio supply device 1000 can transmit an audio signal and control the operation of the illumination device 100. However, the illumination device 100 is controlled by another electronic device by wireless communication or the like. It is also possible.

  Here, another usage method that can be configured in the above-described illumination system will be briefly described. FIG. 13: is a flowchart which shows an example of the other operation | movement process sequence of the illumination system concerning Example 2 of this invention. FIG. 14 is a flowchart showing another example of another operation processing procedure of the illumination system according to Embodiment 2 of the present invention. 13 shows a case where an illumination system having a plurality of illumination devices 100 is used as an interphone, and a process shown in FIG. 14 shows a case where the illumination system is used as a monitoring system using a PLC.

  In the flowchart of FIG. 13, first, for example, in one of a plurality of lighting devices 100 installed on the first and second floors of a building, the control circuit 705 is based on operation information input via a remote controller or a switch. To determine whether the intercom mode is ON (step S1301).

  When it is determined that the intercom mode is ON (step S1301: Yes), for example, a control signal instructing power ON is transmitted to all the lighting devices 100 provided in the lighting system via the power line 310. The control circuit 705 in each lighting device 100 controls the power supply circuit 706 and the like to supply power to the lighting device 100 (step S1302).

  Then, in the lighting device 100 that is the call source, for example, by making a sound toward the microphone 507 while designating the call place, the call place is designated and voice input is performed (step S1303). The input voice is signal-processed by the signal processing circuit 704 and transmitted to the lighting device 100 at the call destination by the control circuit 705.

  The lighting device 100 at the call destination performs signal processing by the signal processing circuit 704 based on the sound signal transmitted from the caller, and outputs the sound at the designated call place by outputting the sound through the speaker 601 ( Step S1304). In these lighting devices 100, the control circuit 705 determines whether or not the intercom mode is OFF based on the operation information input via the remote controller or the switch (step S1305).

  When it is determined that the intercom mode is not OFF (step S1305: No), the process proceeds to step S1303, and the processes of steps S1303 to S1305 are repeated. If it is determined that the intercom mode is OFF (step S1305: Yes), the power supply circuit 706 and the like are controlled by the control circuit 705 of all the lighting devices 100 to stop the power supply to the lighting device 100. The process ends.

  On the other hand, in the flowchart of FIG. 14, for example, a control signal related to ON / OFF for starting the camera 506 is transmitted from the mobile phone or the like to the lighting device 100 installed in the house, and the control circuit 705 of the lighting device 100 Based on this control signal, it is determined whether or not the camera mode is ON (step S1401).

  When it is determined that the camera mode is ON (step S1401: Yes), the control circuit 705 controls the power supply circuit 706 and the like to supply power to the illumination device 100 (step S1402), and the camera 506 performs illumination. An image around the place where the apparatus 100 is installed is captured (step S1403), and image signal processing is performed to convert the image captured by the signal processing circuit 704 into an image format that can be viewed on a mobile phone (step S1404).

  Then, the control circuit 705 controls the communication control circuit 702 to output an image signal-processed via the communication I / F 701 by the power line 310 or wireless communication (step S1405), and a control transmitted from a mobile phone or the like. Based on the signal, it is determined whether or not the camera mode is OFF (step S1406).

  When it is determined that the camera mode is not OFF (step S1406: No), the process proceeds to step S1403, and the processes of steps S1403 to S1406 are repeated. When it is determined that the camera mode is OFF (step S1406: Yes), the control circuit 705 of the lighting apparatus 100 controls the power supply circuit 706 and the like, stops the power supply, and ends the process.

  Thus, according to the illumination system according to Example 2 of the present invention, power supply can be obtained by connecting the illumination device to the existing electric light equipment, and light emission (lighting) and sound output can be performed. Audio output can be performed based on the audio signal from the audio supply device. Further, light emission (lighting) and sound output can be controlled centrally or individually by a sound supply device or the like.

  In addition, there is no need for construction work for installing lighting devices and audio supply devices, and it is possible to install lighting systems in various locations, improving the degree of freedom of installation at a low cost and providing lighting and audio functions. An illumination system that can be used can be realized.

  As described above, according to the lighting device and the lighting system according to the present invention, it is possible to improve the degree of freedom of installation without using a new construction or the like by using the existing electric light equipment. Further, according to the lighting device and the lighting system according to the present invention, it is possible to simultaneously and selectively use the lighting function and the audio function easily and inexpensively.

  In the first and second embodiments, it has been mainly described that the lighting device or the lighting system is turned on / off or the sound output is turned on / off. It is also possible to construct an in-home communication network by using the lighting device and perform data communication, or to construct a more advanced monitoring system by mounting a human body detection sensor, an event change sensor, or the like on each lighting device 100. is there. If it does in this way, it becomes possible to further expand the application range of an illuminating device or an illumination system.

  In the first embodiment and the second embodiment, it has been mainly described that an audio signal for audio output by the lighting device is input by the PLC or by wireless communication or a recording medium. A / FM tuner, a TV tuner, or the like may be installed, and the sound input by these tuners may be output. In this way, it is possible to further simplify the configuration relating to the transmission and reception of audio signals, and to realize an illumination device and an illumination system that can output audio at low cost.

  Moreover, although Example 1 and Example 2 demonstrated on the assumption that it connected to the existing electric light installation and operate | moves by the electric power supply from this electric light installation, portable electric power sources, such as a battery, are employ | adopted as an electric light installation, for example Alternatively, a structure may be employed in which a non-contact type rechargeable battery is mounted on the lighting device, and the electric power from the lamp facility is stored and supplied by electromagnetic induction.

  Furthermore, the lighting device of the first embodiment is installed at, for example, a front door, and a voice signal for outputting a voice such as “Return” is stored in advance in a memory or the like, and the detection signal is detected by a human body detection sensor or the like. Based on this, the lighting device may be configured to automatically output sound.

  Further, in the lighting system of the second embodiment, for example, by providing the audio supply device with an emergency broadcast reception function, it is possible to perform emergency broadcast such as when a disaster occurs by the lighting device. Since this lighting system can use existing electric lighting equipment, it can be applied not only to buildings but also outdoors.

  Further, according to the lighting device and the lighting system according to the present invention, the lighting device can be operated by a remotely operable device such as a remote controller. For example, when a plurality of lighting devices are arranged in one room such as a building, a plurality of speakers 601 are arranged in one room. Therefore, switching by a remote controller is performed based on an ID assigned to each lighting device. If it performs, audio | voice can be output from a desired position.

  In addition, such a remote controller can be used to comprehensively operate the audio supply device 1000, or when the audio supply device 1000 can output audio signals of a plurality of channels, an arbitrary channel can be selected. You can also. In addition, for example, the volume of sound output from the speaker 601 of the lighting device can be adjusted.

  For example, when the audio supply apparatus 1000 has a media playback function such as a DVD, it is possible to operate all the controls related to the media playback function with a remote controller. In this case, first, the audio supply device 1000 may be initially set to enable the media playback function.

  The initial setting may be started by, for example, authenticating a plurality of lighting devices. Specifically, as an authentication procedure of the lighting device, first, a LAN is constructed through the power line 310 between the plurality of lighting devices 100 and the voice supply device 1000 that are arranged, and each lighting device 100 is connected to the voice supply device 1000. ID is notified to.

  Then, the voice supply device 1000 receives the ID notified from each lighting device 100, stores these IDs in a storage means such as a memory, and sends a reception notification with the ID of the voice feeding device 1000 itself to each lighting. It transmits with respect to ID of the apparatus 100. FIG. Each lighting device 100 receives the transmitted reception notification, stores the ID of the sound supply device 1000 in a storage unit such as a memory, and performs authentication.

  Once authentication is performed, communication can be performed between each lighting device 100 and the sound supply device 1000 based on each other's ID. For example, when reproducing 5.1-channel, 6.1-channel, or 7.1-channel audio of a DVD as a media reproduction function, the audio supply device 1000 can set the function of each lighting device 100. Become.

  In other words, as an example of the function setting, the sound supply device 1000 causes the lighting device 100 disposed at which position to be used for the sound of which channel (center) in the sound reproduction such as the 5.1, 6.1, and 7.1 channels. Audio, front LR audio, rear LR audio, woofer audio, etc.) can be set. These settings can also be made with a remote controller. In addition, when the lighting device 100 is equipped with a camera, the position of the human ear is automatically determined based on the video obtained from the camera 506, and based on the determination result, which channel is connected to the plurality of surrounding lighting devices 100. You may make it set automatically whether to output an audio | voice.

  Further, according to the lighting device and the lighting system according to the present invention, for example, a human sensor is mounted on each lighting device 100, and the lamp 602 and the speaker 601 are turned ON / OFF depending on whether or not a human body is detected. May be. In this case, first, the human sensor mode in each lighting device 100 is turned ON by, for example, control from the sound supply device 1000 or operation by a remote controller.

  Then, the control circuit 705 of each lighting device 100 determines whether or not a human body is sensed by a human sensor. If not sensed, the lamp 602 and the speaker 601 are turned off, and if sensed, the lamp 602 is detected. Or the speaker 601 is turned on to turn on the illumination or output sound.

  If the lamp 602 and the speaker 601 are turned on / off in this manner until the human sensor mode is turned off, each lighting device 100 automatically turns on the illumination or outputs sound when a human body is detected. It becomes possible to improve convenience. In other words, even if a person moves to another room or the like, the user can enjoy the music output from the lighting device 100 in the room without any troublesome operations via the lighting device 100 in another room. It becomes possible.
