Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a portable lighting device that uses a solar cell as a power source to light a fluorescent lamp.

[Prior art and its problems]

Portable lighting lamps with built-in dry batteries or chargers that turn on lighting means such as lamps have been used for a long time, but in recent years, solar cells have been attracting attention as a power source, and the light irradiation to these solar cells during the day has increased. Storing the resulting power in a rechargeable battery and using it for nighttime lighting has become popular in street lights and the like.

However, if we consider the characteristics of solar cells,
It is possible to use solar cells regardless of the installation location as long as there is sunlight irradiation, and therefore solar cells are the most suitable power source for portable lighting devices that require portability as emergency lighting devices. At present, it has not yet been fully put into practical use.

The reason for this is that the characteristics of the solar cell and the characteristics of the portable lighting device are not taken into consideration when using the device.

SUMMARY OF THE INVENTION In view of these problems, an object of the present invention is to provide a practical portable lighting device by easily and rationally combining a solar cell as a power source with lighting means.

[Means for solving problems]

In order to solve the above problems, the present invention provides a partition wall in a transparent hollow cylindrical case, arranges a plurality of solar cells on one side of the partition wall, fills it with transparent resin, and in addition A fluorescent lamp is arranged on the direction side, and a battery and a fluorescent lamp lighting circuit are housed at or adjacent to the end of the hollow cylindrical case, so that the fluorescent lamp can be lit by the power of the solar cell. A portable lighting device was constructed.

[Effect]

By configuring as described above, the solar cells arranged on one side of the partition wall can receive sunlight through the transparent cylindrical case and the transparent resin, so the lens effect due to the outer surface of the cylindrical case and the resin In addition to being able to efficiently receive light and generate electricity,
Since the fluorescent lamp is placed on the other side of the cylindrical case, the overall size can be reduced.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a portable lighting device of the present invention, and FIG. 2 is a sectional view taken along the line A--A in FIG. 1 showing the internal structure.

In the figure, reference numeral 1 denotes a transparent hollow cylindrical case, and a similarly cylindrical case 2 is integrated and connected to the end face of the transparent hollow cylindrical case 1. 3
is a partition wall installed in a transparent hollow cylindrical body, and both ends of the partition wall 3 are fixed by a lid 4 provided at the other end of the hollow cylindrical body 1 and a case 2. On one side of the partition wall 3, a plurality of solar cells 5 are arranged in series in a straight line in the longitudinal direction.
One side of the partition wall 3 where the solar cells 5 are arranged is filled with transparent resin 6, so that the solar cells 5 appear to be floating in the space formed by the partition wall 3 and the hollow cylindrical body 1. is supported by On the other hand, a fluorescent lamp 7 is attached to the other side of the partition wall 3. One surface of the partition wall 3 is provided with electrical wiring for supporting and lighting the fluorescent lamp 7, and the other surface is provided with electrical wiring for guiding the power from the solar cell 5 to a lighting means to be described later through a lead wire 8. ing.

Inside the case 2, a battery 9 for charging the power generated by the solar cell 5 and a lighting means 10 for controlling the lighting of the fluorescent lamp, which is composed of electric parts such as transistors and capacitors, are arranged. .
Reference numeral 11 denotes a lighting switch that partially protrudes from the outer surface of the case 2. A rotating plate 12 having substantially the same shape is attached to the end of the case 2 so as to be rotatable with respect to the end surface of the case 2. Reference numeral 13 denotes a locking member that slides and projects from the outer surface of the rotary plate 12, and is provided for fixing the case 2. A scale 14 is displayed on the outer peripheral surface of the end of the case 2 that is in contact with the rotary plate 12, and a locking member 13 that rotates together with the rotary plate 12 is displayed.
The predetermined positions of the locking member 13 and the case 2 can be switched arbitrarily by aligning the moving position with the predetermined position of the scale 14.

That is, the inclination angle of the solar cell 5 fixed in the hollow cylindrical body 1 is determined by the scale of the locking member 13 which can fix the hollow cylindrical body 1 and the case 2 by protruding as shown in FIG. It can be set to protrude in accordance with 14 predetermined positions.

In other words, if the latitude angle is displayed on the scale 14, the solar cell 5 can be installed at an inclination according to the latitude angle of the land by operating the rotary plate 12 and the locking member 13. Efficiency can be improved.

In the above embodiment, the latitude scale is displayed on the case 2 side, but it is displayed on the rotating body 12 itself, and the rotational position of the case 2 is determined according to the reference position on the case 2 side, and the inclination angle of the solar cell 5 is determined. It may be changed.

Furthermore, the locking member 13 and the scale position are not limited to the above embodiment side, but may be provided on the lid 4 side, or may be provided on both sides.

Alternatively, the case 2 or the lid 4 may have a polygonal shape, and the installation angle of the solar cell 5 may be changed by rotating the cylindrical body 1 at a predetermined angle depending on the external shape.

[Effect of idea]

As explained above, in this invention, a transparent hollow cylinder is divided into two by a partition wall, a solar cell is placed on one side, and the space is filled with transparent resin, which increases the power generation efficiency of the solar cell. In addition, since the fluorescent lamps are placed on the other side, the storage space for these lamps can be reduced. Furthermore, since a latitude scale and a locking means are provided, the power generation efficiency can be improved and the fluorescent lamp used as the lighting device can be fixed, making it practical as a portable lighting device.
