Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a warning light that alerts the driver of a vehicle at sharp curve points on roads, railroad crossings, etc.

[Prior art and its problems]

Traditionally, warning lights have been installed at sharp road curves, railroad crossings, mountainous areas, etc. to alert vehicle drivers by rotating or flashing light sources (xenon discharge tubes, light bulbs, etc.). .

However, in order to turn on the above light source, it is necessary to supply relatively high voltage and stable power from a commercial power source, but depending on the location where the warning light is installed, it may be extremely difficult to connect the commercial power source and install it. be.

In addition, in areas such as riverbeds that are used as wide-area evacuation sites, commercial power cannot be drawn in, and they cannot serve as warning lights at all in the event of a power outage in the event of a disaster.

Furthermore, the lifespan of the xenon discharge tube used as the light source of the warning light is about one year, and the lifespan of the light bulb is also about half a year, so replacing and repairing the light source requires a great deal of cost and effort.

Therefore, in order to simplify the above-mentioned installation and repair work and maintain high reliability in the event of a disaster, the present applicant has developed a reflector cover with a vertical slit provided on the outer periphery of the main body, and a We proposed a warning device with a solar cell, which consists of a light source board on which light emitting diodes are fixed in a radial manner, and the light emitting diodes are made to blink using a solar cell (Utility Application No. 59-62858).

As shown in the installation example in FIG. 4, this device has a solar cell module 22 including a solar cell 2 fixed to the top of a support pole 9, and a warning light 1 mounted on a pedestal 91 integrated with the support pole 9. placed. Here, wiring connecting the solar cell module 22 and the warning light 1 is provided inside the support pole 9.

However, in the above device, it is extremely difficult to provide electrical wiring inside the support pole 9, and
It is even more difficult to carry out repair work on this electrical wiring. In order to solve this problem, it is conceivable to integrate the solar cell module 22 into the upper part of the cover of the warning light 1. In other words, in view of cost, there is a concept of manufacturing the solar cell module and warning light separately and integrating them in the final process.
For this reason, there is a risk that moisture may enter from the joint between the solar cell module 22 and the cover of the warning light 1, the portion where the lead wire led out from the solar cell 2 enters the cover of the warning light 1, etc., which is a problem.

[Purpose of invention]

The present invention was devised in view of the above-mentioned problems, and even if the warning light is installed in a place where commercial power is not available, it can perform its function satisfactorily, and it can also be used for a long period of time without being exposed to sunlight. To provide a long-life and highly reliable warning light by preventing dirt on a battery module and suppressing reduction in light transmittance.

[Means for solving problems]

In order to achieve the above object, the present invention provides a reflector equipped with a plurality of light emitting diodes on the side periphery of a substantially columnar base, and also provides a ridge-like curved thick part on the light-receiving surface side with a thickness of approximately 30 to 40 mm. The present invention is characterized in that a cap-shaped solar cell module equipped with a plurality of translucent covers formed at an inclination angle of 1.5 degrees is disposed above the base.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

As shown in FIGS. 1a and 1b, the warning light 1 fixes internal structures such as a solar cell module 22, a light emitting diode 4, and a diamond-cut reflector 5 covering a plurality of light emitting diodes 4 as a set. It consists of a base 6 and a translucent cover 7 that covers the entire internal structure.

Here, the solar cell module 22 is in the shape of a cap equipped with a translucent cover 3 having a plurality of ridge-like curved thick sections formed on the light-receiving surface side along an inclined surface, which will be described later. It is fixed in a removable manner.

The solar cell 2 is a power source for the light emitting diode 4, and is made of materials such as crystalline silicon, amorphous silicon, GaAs, and polymer semiconductors, and generates electricity when exposed to light of a certain level or higher.

The translucent cover 3 has a cylindrical shape with an inclined surface 31 of about 30 to 40 degrees to which the solar cell 2 is attached from the inside, and is made of transparent polycarbonate resin or the like. The solar cell 2 is wired so as to obtain predetermined power characteristics, and is tightly covered with an adhesive 32 such as silicone resin inside the inclined surface 31 of the transparent cover 3 .

On the front side of the inclined surface 31 of the translucent cover 3, four ridge-shaped curved thick portions extending in the inclined direction are formed. This ridge-like curved thick part has a surface radius of 35 mm in order to have a lens effect (increase the concentration of sunlight).
It is formed into a curved surface of ~55mm, and between the ridges,
The curved surface is formed to have a radius of curvature smaller than that of the curved wall thickness, for example, about 10 mm radius, for ease of processing, aesthetic beauty, and to allow dirt such as dust in the atmosphere to be easily washed away by rain.

In this way, if the translucent cover 3 is installed with the slope 31 facing south, the light will be highly concentrated not only at midday when the sun is near the center of the south, but also when the sun is at a low position such as in the morning or evening. The effect can be expected,
Further, dirt adhering to the slope 31 can be easily washed away by using the valleys during rain or the like.

The base 6 is provided with a polygonal column-shaped accommodating portion 61 that supports and accommodates internal structures. The housing portion 61 has an upper space 62 and a lower space 63.

Wiring is provided between terminals (not shown) that the electrodes of the solar cell 2 and the secondary battery 8 come into contact with, and a cover 7 that completely covers these internal structures is provided. The cover 7 is screwed onto the base 6 via an O-ring 71, which is a packing member, so as to firmly and airtightly join the base 6. This completely blocks moisture from entering the inside of the warning light due to rain, etc., and also completely blocks sea breeze at ports etc., and prevents corrosion of the terminals of the light emitting diode 4, the electric circuit board 6, the secondary battery 8, etc. There will be no malfunctions caused by this.

The cover 7 has at least a side surface corresponding to a portion of the reflector 5 formed by injection molding of transparent polycarbonate resin or the like. The peripheral edge of the solar cell module 22 fits into the upper part of the cover 7 and is fixed by screwing.

As shown in FIG. 2, insert nuts 73a and 73b that can be screwed onto the transparent cover 3 from the side of the transparent cover 3 are embedded in the thick curved portion of the upper surface 72 of the cover 7. Further, at the center of the upper surface 72 of the cover 7, the end of the injection molded resin remains as a protrusion 74.

The translucent cover 3 of the solar cell module 22 has fixing bolts 23a, 2 of the translucent cover 3 at positions corresponding to the insert nuts 73a, 73b.
Notches 24a, 2 are provided to facilitate screwing of screw 3b.

Thus, the translucent cover 3 is placed over the cover 7 of the warning light 1, and a part of the cover 7 is fitted with the skirt-like hem 25. Furthermore, the fixing bolts 23a, 23b are screwed into the notches 24a, 24b of the translucent cover 3 and the insert nuts 73a, 73b of the cover 7 via the translucent cover 3. As a result, the cover 7 of the warning light 1 and the translucent cover 3 are completely integrated.

Here, as a joining means, an insert nut 73a embedded in the curved thick part of the scene 2 of the cover 7,
73b and fixing bolts 23a, 23b are used, the protrusion 74 remaining at the center of the upper surface 72 of the cover 7 is cut at a predetermined height, for example along the Z-Z' line. Formed opening 7

If the opening 75 through which the lead wire passes is filled with an adhesive such as silicone resin, moisture will not enter through the opening 75.

As shown in FIG. 3, a support pole 9 is erected at a dangerous location where it is difficult to obtain commercial power or a location where the driver of a vehicle should be alerted, and a mount 91 is mounted on the top of the support pole 9 to attach a warning light 1. Installed via.

In this way, when the power generated by the solar cell 2 decreases, the blinking control circuit (not shown) of the electric circuit board 64 senses this and starts emitting light using the power of the secondary battery 8 charged with the electromotive force of the solar cell 2. Diode 4 flashes.

Alternatively, the warning light 1 may be constructed by leaving the protruding portion 74 as it is and connecting it to a built-in DC power source.
In this way, any power source can be used depending on the installation conditions.

[Effect of idea]

As described above, according to the warning light of the present invention, since the solar cell module is cap-shaped, even if dust etc. accumulates on the solar cell module, it is easily washed away by rain, etc., and cleanliness is always maintained. Since the surface side is ridged, the effect is large and the power generation efficiency of the solar cell module does not decrease.

In addition, the solar cell module is equipped with a translucent cover with multiple curved thick sections formed at an inclination angle of approximately 30 to 40 degrees on the light-receiving surface side of the solar cell module. It has an effective light-concentrating effect even in the morning, evening, and on cloudy days, and can improve the power generation efficiency of solar cells.

Furthermore, since the rigidity of the solar cell module is improved by the ridged curved thick portion, the solar cell can be sufficiently protected against external impacts.
