[0001]

[Industrial applications]

 The present invention relates to a light emitting device using a solar cell.

[0002]

[Prior art]

 A solar cell is installed on the surface of the box, and a storage battery that stores the electric power generated by the solar cell is stored in the box, and a light-emitting lamp that emits light by the power of the storage battery and emits light to the outside of the box. A solar cell light emitting device in which the box body is provided and only the solar cell surface is exposed and embedded in the ground is commercially available as Lumitile (trade name).

[0003]

[Problems to be solved by the device]

 However, since this Lumitile box has an airtightly sealed structure, it was greatly affected by operations in the ground and the temperature of the outside air, which was an obstacle to extending the service life.

Therefore, it is conceivable to stop the airtight sealing structure and provide a ventilation port on the side surface of the box body to allow ventilation, but rain or mud penetrates through the ventilation port and damages the internal structure. There was a new problem that caused it.

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a sectional view of a solar cell light emitting device according to the present invention. Reference numeral 1 denotes a box forming a solar cell light emitting device, which is a cube made of, for example, vinyl chloride or FRP and having a length of 20 cm, a width of 20 cm, and a thickness of 20 cm. Reference numeral 2 is a solar cell made of amorphous silicon that generates power when it is irradiated with light such as sunlight. The solar cell 2 is provided on the surface of the box 1 and only the surface of the solar cell 2 is exposed to the ground. As the solar cell 2, a semitransparent solar cell (product name: see-through-amolton) that can transmit light is used. A storage battery 3 such as a nickel-cadmium battery is installed at the bottom of the box body 1 and stores the electric power generated by the solar cell 2. Reference numeral 4 denotes a light emitting means composed of a light emitting diode (LED), which is lit by electric power from the storage battery 3 and is provided below the solar cell 2 of the box body 1. Light from the light emitting means 4 is provided. Is radiated to the outside of the box body 1 through the semitransparent solar cell 2. A ventilation unit 5 is provided on the side surface of the box body 1 and can prevent hot air and high humidity of the apparatus in the box body 1.

2 and 3 are an enlarged cross-sectional view of the ventilation part 5 and an enlarged perspective view showing parts of the ventilation part 5 of the solar cell light emitting device according to the present invention. A through hole is provided on the side surface of the resin plate of the box body 1, and a bolt 6 having a diameter slightly larger than the diameter of the through hole in which the knurling is engraved is fitted on the surface of the through hole. There is. This bolt 6 is a metal pipe made of iron with a head at one end and a thread at the other end, a hole 7 is opened in the head part, and a functional sheet 8 is provided in the pipe at the tip of the screw part. Cover and attach. This functional sheet 8 is a waterproof breathable material, and is a sheet that allows gas such as air, moisture, and gas to pass through, but does not allow water to pass within a water-resistant pressure. For example, the "polyolefin microporous functional sheet" is used. The product names are on sale with the trade names of "-Micropore NF Sheet" and "Polytetrafluoroethylene Porous Membrane Cyclotex".

Further, a nut 9 that fits into the screw at the other end of the bolt 6 is provided. The nut 9 is a lid body that is combined with the bolt 6 with a screw, and has a functional sheet 8. The pores 10 are provided in the contacting portion so that ventilation is performed.

As described above, in the attached box body 1, only the solar cells 2 are exposed to the ground and embedded in the ground. At the time of sunshine, the solar cell 2 is irradiated with sunlight. This solar cell 2 generates electricity with a high output, and the electric power is charged into the storage battery 3.

On the other hand, in the evening, when power generation by the solar cell 2 is stopped, electric power is supplied from the storage battery 3 to the light emitting means 4 and the light emitting means 4 is lit, and the light is translucent solar cell 2 Is radiated to the outside of the box body 1 through.

On the other hand, if the device installed in the box body 1 is always operated, the temperature inside the device is raised and the device is likely to be damaged by rust of the device due to rainwater or the like. Therefore, a ventilation sheet 5 attached to the box 1 enables ventilation in the box 1 by a functional sheet 8 in order to keep high temperature and high humidity air in the box 1 at low temperature and low humidity. be able to. This is because, for example, when the temperature becomes high due to the entire apparatus, hot air is passed through the pores 10, the functional sheet 8 that only passes the gas is passed, and further, the hot air is passed through the pores 7 of the bolt 6 for ventilation. It On the other hand, when there is a drop of water outside the box 1 due to rainwater or the like, the water passes through the pores 7, but the functional sheet 8 does not allow water to pass but only moisture or air. Only gas is passed through the pores 10 and taken into the box 1. As a result, the device is not hindered.

Next, FIG. 4 shows another embodiment of the solar cell light emitting device of the present invention. The same components as those shown in FIG. 2 are designated by the same reference numerals.

Reference numeral 11 denotes a second functional sheet provided in contact with the pore 7 on the inner surface of the head of the bolt 6, and the first functional sheet covered with the pipe at the tip of the threaded portion of the bolt 6. -The same material as the sheet 8 is used. Only moisture and air from the pores 7 are allowed to pass therethrough to prevent water from accumulating in the tube of the bolt 6 and, in cooperation with the functional sheet 8, Prevents water from entering the box without impairing the ventilation function inside the box. A cylindrical spacer 12 is provided for arranging the first and second functional sheets 8 and 11 at predetermined positions on both inner and outer surfaces of the bolt 6. Due to the presence of the spacer 12, the functional sheets 8 and 11 are held at predetermined positions and the ventilation function is secured, so that the device is not hindered.

In the figure, the functional sheet 8 may be omitted and only the functional sheet 11 may be provided.

FIG. 5 shows still another embodiment of the solar cell light emitting device of the present invention, in which a lid attached to the bolt 6 is provided with a ventilation hole so as to be parallel to the side surface of the box body, which is shown in FIG. Parts that are the same as those described above are given the same reference numerals. Reference numeral 13 is a nut that is fitted into the screw at the other end of the bolt 6, and this nut 13 is a lid body that is combined with the bolt 6 with a screw and is provided with a ventilation hole 14, and is in contact with the functional sheet 8. The nut 13 is installed so that the vent hole 14 thereof is parallel to the side plate of the box body and can be ventilated upward. With this arrangement, when there is a water drop outside the box body 1, the water passes through the pores 7, but the functional sheet 8 allows moisture and air to pass through instead of passing through the water. It is passed through the ventilation holes 14 and taken into the box body 1.

However, even if water should pass through the functional sheet 8 and enter the nut 13, the ventilation hole 14 is provided upward on the side surface of the box body, so that the water is stored in the box body 1. There is no danger of getting inside. As a result, it is possible to smoothly ventilate the inside of the box without any hindrance to the device.
