[0009]

[Action]

 According to the present invention, a cylindrical light receiving window penetrating into and out of the adapter body is provided on the lower surface of the adapter body, and the inner surface of the cylindrical light receiving window is white. Insulation distance is secured, and when the optical wireless signal transmitted from the remote control transmitter passes through the light receiving window, the inner surface of the light receiving window is white, which improves the reflection efficiency, and therefore the optical wireless signal received by the light receiving section. The attenuation of the can be reduced, and the operable distance from the remote control transmitter can be extended.

[0010]

【Example】

 Hereinafter, the present invention will be described with reference to examples. As shown in FIG. 1, the adapter for remote control of lighting equipment of the present embodiment has an adapter body 1 formed of an upper case 1A and a lower case 1B. The upper case 1A has an upper surface on which a ceiling-side hooking sealing body is hooked. A point where a hook plug blade 2 to be connected is projected and an insertion hole 13 for inserting the hook plug blade of the hook ceiling provided on the tip of the power cord of the pendant type lighting fixture is provided on the lower surface of the lower case 1B and the lower case 1B. As shown in FIG. 2, the printed circuit board 4 on which the circuit elements of the remote control receiver are mounted is built in, and the light receiving part 10 composed of the light receiving element is provided on the lower surface of the printed circuit board 4 with the light receiving surface facing the lower surface of the lower case 1B. The configuration is basically the same as that of the conventional example in that it is implemented toward.

On the lower surface of the lower case 1B, a light emitting diode 12 for receiving and displaying is provided, and a switch SW _{1 for} turning on / off a voice for selecting whether to notify the reception by sound or manual illumination. Auxiliary switch SW ₂ for turning the device on and off, reset switch SW ₃ for resetting the initial state when the CPU that constitutes the control circuit of the remote control receiver runs out of control, etc. Each operation unit of the channel setting switch SW ₄ for switching and setting the channel is exposed. Further, a predetermined number of mounting holes 15 for mounting the lower cover 3 for covering the lower surface of the adapter body 1 shown in FIG.

Now, a hole 16 penetrating in and out is provided on the lower surface of the lower case 1B facing the light receiving surface of the light receiving unit 10. The hole 16 has a lower hole 16A having a circular cross section and a hole having a rectangular cross section. 16B and a two-stage hole, and a bushing 17 made of white-painted plastic, the lower part of which is a cylinder and the upper part of which is a prism, is inserted into this hole 16. The square tube portion of the bushing 17 thus inserted is accommodated in the hole 16B, and the light receiving surface of the light receiving module 10A of the light receiving section 10 is closely arranged and faces the opening of the upper surface of the square tube portion. The lower end of the cylindrical portion of the bushing 17 projects downward from the lower surface of the lower case 1B. FIG. 3 is a bottom view of the protruding portion of the bushing 17 as seen from below the lower case 1B.

Thus, the optical wireless signal such as infrared light transmitted from the remote control transmitter enters the inside of the light receiving window 18 formed by a small-diameter through hole in the bushing 17 from the lower end opening of the bushing 16. Then, the light is reflected by the white inner surface of the light receiving window 18 and received by the light receiving unit 10. In the conventional light receiving window having a black inner surface, the reflectance of infrared rays is 4%, whereas in the light receiving window having a white inner surface as in the present embodiment, the infrared ray reflectance is as high as 90% or more. Become a rate. Of course, this is the case when the materials used are the same.

In the case where the lower case 1B made of transparent plastic or milky white plastic having the light receiving window 18 and having a thickness of, for example, 2 mm is formed as described above, the former has a transmittance of 90% or more, and the latter has an infrared transmission of about 50%. However, in the former case, there is a problem that the inside of the adapter body 1 is completely visible and both parts are directly touched by the hands, so that there is a problem that the transmittance is reduced and the transmittance is reduced. By configuring the light receiving window 18 with a small-diameter hole 17, the inside of the adapter body 1 cannot be seen and the inner surface is not touched by a finger, so the reflectance does not decrease and the performance is stable.

The shape of the bushing 17 may be formed by a large diameter cylindrical portion and a small diameter cylindrical portion as shown in FIGS. 4 and 5, and in this case, the lower case 1B through which the bushing 17 is inserted. The corresponding holes are also formed so as to correspond to the bushing 17. Although the bushing 17 is used in the above embodiment, the same effect can be obtained by integrally forming a cylindrical light receiving window in the lower case 1B and applying white coating on the inner surface thereof.

[0016]

[Effect of the device]

 According to the present invention, a cylindrical light receiving window penetrating the inside and outside of the adapter body is provided on the lower surface of the adapter body, and the inner surface of the cylindrical light receiving window is white. When the optical wireless signal transmitted from the remote control transmitter passes through the light receiving window while ensuring the insulation distance, the reflection efficiency is improved because the inner surface of the light receiving window is white, and therefore the optical wireless signal received by the light receiving section. This has the effect of reducing the attenuation of the signal and increasing the operable distance from the remote control transmitter.
