[Related Art] In recent years, a wireless switch system that wirelessly controls the operation of a load has been developed in order to eliminate the wiring between a load such as a lighting fixture and a switch for controlling the operation of the load and to facilitate the installation. In this wireless switch system, a wireless transmitter transmits a control signal for controlling the operation of a load from a wireless transmitter, a wireless receiver provided on the load side receives the control signal, and loads the control signal in accordance with the control signal. Operation control.

[Problems to be Solved by the Invention] However, in the above-described wireless switch system, a power source is also required on the wireless transmitter side, and in particular, when carrying is possible, the wireless transmitter needs to include a battery. For this reason, it is necessary to replace the battery, and there is a problem that the transmitter becomes large in size because the battery is built-in.

The present invention has been made in view of the above points, and an object of the present invention is to provide a wireless switch system that does not require a power supply on an operation device side that sends a control signal for controlling the operation of a load. is there.

Means for Solving the Problems In order to achieve the above object, the present invention provides a control device connected to a load for controlling the operation of the load, and an operation of sending a control signal for controlling the operation of the load to the control device. Device
The operating device modulates the light projected from the control device, reflects the light, and sends a control signal to the control device.

As the modulation means for modulating the light projected from the control device in the operation device, for example, the reflection of light to the control device is intermittently performed in accordance with the operation of an operation unit such as a switch to perform optical modulation. What to apply may be used.

[Operation] According to the present invention, the operating device modulates the light projected from the control device and transmits the control signal to the control device by reflecting the modulated light. No electrical circuit such as a transmission circuit for transmitting an optical signal is required, and no power supply is required on the operation device side.

[Embodiment] FIGS. 1 to 6 show an embodiment of the present invention. In this embodiment, as shown in FIG. 1, a lighting system that performs lighting control of a lighting device as a load is illustrated as an example of a wireless switch system, and a lighting device 3 is connected to a signal line (or a power supply line). A control device 1 connected via l ₁ for controlling the lighting of the luminaire 3;
An operation device 2 for sending a control signal for controlling the lighting of the luminaire 3 to the control device 1. The operation device 2 modulates the light projected from the control device 1 and reflects the modulated light.
To send a control signal. Here, in this lighting system, the control device 1 is arranged on the ceiling together with the lighting fixture 3, and the operation device 2 is arranged on the wall surface. Incidentally, as shown by an operation device 2 'in FIG. 1, it may be movable.

As shown in FIG. 2, the control device 1 includes a light projecting unit 11 for projecting light, and a light receiving unit 12 for receiving reflected light from the operating device 2.
A filter unit 14 that discriminates a control signal that is a modulation component from a received light output, an amplification unit 15 that amplifies the discriminated control signal, and a control unit 16 that performs lighting control of the lighting apparatus 3 according to the control signal. A half mirror 13a that transmits light from the light projecting unit 11 downward and reflects reflected light from the operating device 2 so as to be incident on the light receiving unit 12, and a condensing lens 13b.
And a diffusion optical system 13c for diffusing the light of the lens 13b.

Further, as shown in FIG. 3, the operating device 2 includes a reflecting plate 21 that reflects the light projected from the control device 1 through an optical system 24 that transmits light, and a lighting device 3 for lighting the lighting device 3. The control unit includes an operation unit 22 such as a switch that is operated at the time of control, and a modulation unit 23 that modulates light emitted from the control device 1 in accordance with the operation of the operation unit 22. Here, as the reflecting plate 21, a recursive type that reflects the reflected light on the same path as the light projected from the control device 1 is used, and a push button switch is provided as the operation unit 22.

Here, a specific example of the modulating unit 23 is shown in FIG. 4 and FIG. As shown in FIG. 5 (a), the modulator 23 of this embodiment is a disk-shaped rotary plate 2 having a plurality of square holes 24a formed concentrically.
4, a fixed plate 25 having a square hole 25a formed at a position corresponding to the square hole 24a of the rotary plate 24 as shown in FIG.
The fourth is for transmitting the operation state of the operation unit 22 to the gear unit 24b of the
The belt 26 shown in FIG. Here, the rotating plate 24
The fixing plate 25 is arranged at right angles to the light traveling direction. In the case of this embodiment, the square hole 25a of the fixing plate 25 is one.
Although there are a plurality of pieces, a plurality may be used.

The light projecting unit 11 of the control device 1 of the present embodiment emits light at all times or at regular intervals. Now, assuming that the operating section 22 composed of a push button switch is pressed, the belt 26 slides as shown by the arrow in FIG. 6 in accordance with the pressing operation of the push button switch, and at this time, the leading end moves upward. The gear 2 is formed by the convex teeth meshing with the gear portion 24b of the rotating plate 24.
The rotating plate 24 is rotated through 4b. Therefore, when the position of the square hole 24a coincides with the position of the square hole 25a of the fixed plate 25 in accordance with the rotation of the rotating plate 24 at this time, the light emitted from the control device 1 as shown by the arrow in FIG. Is reflected by the reflection unit 21 to the control device 1. That is, the reflection of light is intermittently performed in accordance with the position where the square hole 24a of the rotating plate 24 is formed, and is transmitted to the control device 1 as an arbitrary pulse signal. Therefore, the control device 1 can receive a control signal for controlling the lighting of the luminaire 3 by detecting the modulation component of the light returned from the operation device 2, and according to the control signal, the control device 1 Controls the operation of the lighting apparatus 3. As described above, in the present embodiment, the operation position 2 reflects the light from the control device 1 and sends a control signal, and the modulation unit 23 of the operation device 2 reflects the reflected light by the mechanical movement of the operation unit 22. Therefore, an electric circuit for transmitting a control signal is not required, and therefore, a power source is not required on the operation device 2 side. Therefore, there is an advantage that it is not necessary to replace the battery as in the case where the battery is used as a power source, the size can be reduced, and the operating device 2 can be formed into an arbitrary shape. Although the case of the push button switch has been described as the unit 22, other operation types such as a slide type and a lever type may be used, and a transmission mechanism from the operation unit 22 to the rotating plate 24 is limited to the belt 26. not.

[Effects of the Invention] As described above, the present invention includes a control device connected to a load to control the operation of the load, and an operation device that sends a control signal for controlling the operation of the load to the control device. Since the device modulates the light projected from the control device and reflects it to send a control signal to the control device, an electric circuit such as a transmission circuit for transmitting an optical signal is provided on the operation device side. It is possible to eliminate the need for a power source on the operation device side.
