Hereinafter, embodiments of the floating visual recognition device according to the present invention will be described with reference to the drawings.
A floating visual recognition device 1 shown in FIG. 1 is formed in a hollow shape and includes a floating body 2, a solar cell device 20 attached to the floating body 2, and an optical medium that emits light from the solar cell device 20. With.

  The floating body 2 has a spherical shape like a general-purpose buoy, and is made of a resin, hard plastic (FRP), or the like having corrosion resistance, weather resistance, and strength. Moreover, although the said floating body 2 is connected so that isolation | separation is possible from the approximate center part in the figure, you may shape | mold integrally without limiting to this.

  In particular, the floating body 2 is formed to be translucent or semi-translucent so that light emitted from the internal light emitter 10 can be illuminated to the outside. Thereby, the floating visual recognition device 1 can be brightly illuminated at night or in the dark.

  The solar cell device 20 is formed by a solar panel 21 and a battery device 22 in which a charger and an optical sensor are integrated. The solar panel 21 converts solar energy into electric energy. In addition, a rechargeable battery (not shown) that stores electric power generated by the solar panel is accommodated in the charger. The light sensor has a function of sensing a change in the amount of light when the surroundings become dark and causing the light emitter 10 to emit light by the power of the charger, and automatically stopping the power transmission when the surroundings become bright. Needless to say, the structures of the solar panel 21 and the battery device 22 are not limited to those described above, and the solar panel 21 and the battery device 22 may be connected by a cord or may be moved in arrangement.

  The solar panel 21 and the battery device 22 are accommodated on the upper surface of a support 23 that is erected at equal intervals. The light emitter 10 is installed in the battery device 22 so as to illuminate the lower part. A reflecting mirror 24 that reflects light emitted from the light emitter 10 is provided below the light emitter 10. By providing the reflecting mirror 24, it is possible to irradiate light emitted from the light emitter 10 over a wide range. Further, a weight 25 is fixed inside the reflecting mirror 24 to keep the floating state of the floating body 2 constant.

  As another preferred example, a reflector 3 that diffusely reflects the light of the light emitter 10 is installed inside the floating body 2. The reflecting material 3 is made of a small piece of aluminum foil or the like, and a plurality of the reflecting materials 3 are installed inside the floating body 2. As a result, the light emitted from the light emitter 10 can be diffused efficiently and the light emission luminance of the floating body 2 can be increased.
