The switch device 300 performs communication settings for the wireless communication device 400 based on the operation of the setting switch 3034. Thereby, the wireless communication setting can be performed at any timing such as when the switch device 300 and the wireless communication device 400 are installed or after the installation.

  Note that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

  In the above-described embodiment, the number of lighting devices that are existing loads is four, but it may be more or less than this.

  Although the power source of the above-described embodiment is the system power source 100, it may be a power source supplied from solar power generation or wind power generation.

  The lighting devices 200 to 230 of the above-described embodiments may be the same type of lighting device or may be different.

  Various buttons and switches such as a push button, a toggle switch, a slide switch, and a rotary switch can be used as the switch 3031, the buttons 3032 and 3033, and the setting switch 3034 of the operation unit 303 according to the above-described embodiment.

  The antenna 401 in the above-described embodiment is not limited to a dipole antenna, and may be a pattern antenna mounted on a substrate.

  The mounting portion 405 of the above-described embodiment is not limited to a notch, and may be a screw hole, a locking portion, a latching portion, or the like.

  The wireless communication system in the above-described embodiment is a Wi-Fi system, but a wireless LAN other than Wi-Fi, Bluetooth (registered trademark) or ZigBee (registered trademark), which is one of short-range wireless communication standards, and the like This method may be used.

  In the embodiment described above, the switch device 300 includes the setting switch 3034 in the operation unit 303, but may be included in the wireless communication device 400. Further, the information collection device 500 includes the WPS push button 501, but may be included in the switch device 300 or the wireless communication device 400.

  The display unit 304 according to the above-described embodiment may display the state of the lighting devices 200 and 210 by using a blinking pattern of LEDs.

  In the embodiment described above, the display unit 530 of the information collection device 500 displays the surface of the switch box 700 where the radio wave intensity from the wireless communication device 400 is the strongest, but is displayed on the display unit 304 of the switch device 300. You may make it do. For example, instead of the second display unit 3042, a third display unit 3043 which is a 7-segment LED shown in FIG. When measuring the radio field intensity, the third display unit 3043 displays “U” (indicating the top surface) and “0” (indicating the bottom surface) close to “D” for the surface of the switch box 700 where the radio field intensity is strongest. ), “L” (indicating the left side), “R” (indicating the right side), “8” (indicating the back side) close to “B”, and the like. Note that the third display unit 3043 displays a number indicating the degree of dimming in conjunction with the operation of the buttons 3032 and 3033.

  According to this configuration, a display indicating the surface of the switch box 700 having the highest radio field intensity is displayed on the display unit 304 of the switch device 300. Therefore, it is not necessary to go to the display unit 530 of the information collection device 500, and the mounting workability of the wireless communication device 400 is excellent.

  In the above-described embodiment, the received radio wave intensity is measured when the wireless communication device 400 is attached to all surfaces of the switch box 700, but it is attached to some surfaces (for example, the left side surface and the right side surface). The best side of some of the surfaces may be determined as the mounting surface from the received radio wave intensity.

  In addition, the determination unit 520 of the information collection device 500 determines that the received radio wave intensity exceeds a predetermined threshold value (reference value), and displays a good display on the display unit 530. It may be displayed on the display unit 304 of the switch device 300. In this case, it may be determined that the first measurement is good, and it is not necessary to measure all surfaces of the switch box 700.

  In the embodiment described above, the switch box 700 is removable from the wall surface WL, but it may be fixed to a pillar or the like and cannot be removed. In this case, the switch device 300 may be positioned inside the switch box 700 after the wireless communication device 400 is attached to the outside of the switch box 700 through the opening 710.

  In the embodiment described above, the wireless communication device 400 can be attached to the plurality of attached portions 730 of the switch box 700. However, as shown in FIG. It may be attachable to (upper surface, lower surface, left side surface, right side surface, and back surface position). The wireless communication device 400 can change the arrangement position through the opening 310 formed in the main body 320. For example, when the switch box 700 is formed of a non-metallic material (for example, a resin molding material) or when the switch box 700 is not used, the wireless communication device 400 is connected to the plurality of attached portions 330 of the main body 320. There is an advantage of disposing.

  In the above-described embodiment, the wireless communication setting is performed by the WPS at the timing of step S102. However, the communication setting may be performed after fixing the switch device 300 or the like.
