Description

  The present invention relates to a disaster prevention lighting column that can reliably illuminate the surroundings even when a power failure occurs due to a disaster or the like.

  There have been over 100 earthquakes with seismic intensity of less than 5 in the past 10 years, including the Great Hanshin-Awaji Earthquake and the Chuetsu Earthquake in Niigata, and it is no wonder where large earthquakes occur anywhere in the Japanese archipelago. Nevertheless, the current situation is that there are almost no nationwide lighting lamps that can respond to power outages during disasters in and around evacuation areas. The Hanshin-Awaji earthquake caused 2.6 million power outages, and it took about one week (152 hours) to complete emergency power transmission. The night of a power outage at the time of a disaster is different from a normal night, and it becomes a darkness of jet black. In recent years, attention has been focused on disaster prevention nationwide, but there are few illuminating lamps that can respond to power outages, which should be very important, and there is no need to maintain independent illuminating lamps for condemnation and rescue activities. It is urgently required.

The following are mentioned as a prior art relevant to this invention.
-JP 2002-25314 A (conventional example 1)
-JP-A-6-162814 (conventional example 2)
In the conventional example 1, an illumination column including a solar cell and a wind power generator is described. In addition, it is described that the column portion of the illumination column can be divided in the vertical direction. However, the conventional example 1 does not describe the material of the column portion. In addition, use for disaster prevention is not described.
Conventional example 2 describes a street lighting support using aluminum as a prior art (paragraph [0004]). However, the specific configuration is not described. In addition, use for disaster prevention is not described. Furthermore, it does not describe the power generation device.

  An object of the present invention is to provide a light column for disaster prevention that is lightweight and compact and easy to install. Moreover, since it is used at the time of disaster prevention, it needs to be excellent in reliability, durability against aging deterioration, and excellent in earthquake resistance.

In order to solve the above-mentioned problems, a disaster prevention lighting column according to claim 1 of the present invention includes a column, a small wind power generator and a small solar cell provided on the uppermost part of the column, the small wind power generator and the small column. In a disaster prevention lighting column comprising a battery for storing electric energy from a solar cell and an LED lighting device provided on the top of the column, the column is made of aluminum, and the surface of the column is anodized. It is characterized by being.
The disaster prevention lighting column according to claim 2 of the present invention is characterized in that the column can be divided in the vertical direction.
The disaster prevention illumination pillar according to claim 3 of the present invention is characterized in that a switch is provided between the battery and the LED illumination device.
Moreover, the illumination pillar for disaster prevention of Claim 4 of this invention is characterized by the said LED illuminating device being covered with the cylindrical transparent plastic.

  Since the illumination column of the present invention is a hybrid power generation method using both wind power generation and solar cells, it can be reliably charged without being influenced by the weather and air volume, and can be reliably illuminated in the event of an emergency. High reliability for disaster prevention. A normal lighting column requires a sufficient amount of light emitted from the lighting device to ensure the brightness of the surroundings, but the lighting column of the present invention is limited to use for disaster prevention, so it provides the minimum necessary light in the event of a disaster. As long as it is possible, the amount of light emitted from the lighting device may be smaller than that of a normal lighting column. In general, a hybrid power generation type illumination column has a plurality of power generation devices, so that the upper part of the support column becomes heavy. However, the illumination column of the present invention includes an illumination device, a wind power generation device, a solar cell, and a battery. Smaller and lighter than that. This is because the amount of light emitted from the lighting device may be smaller than that of a normal lighting column, so that the amount of power generation can be reduced, the power generation device can be reduced in size, and the amount of stored electricity can be reduced, so that the battery can also be reduced in size. Ordinary lighting columns are made of iron or concrete to support larger lighting devices, wind power generators, solar cells, batteries, but the lighting columns of the present invention are for disaster prevention, As described above, the wind power generator, the solar battery, and the battery may be small and light, and can be supported even if the prop material is aluminum. By making the material of the column aluminum, the overall weight can be dramatically reduced, and the portability and installability are greatly improved.

In paragraph [0004] of Conventional Example 2 above,
“On the other hand, street lighting columns using aluminum molds are also known in the past. However, in this known street lighting column, since the columns are composed only of aluminum molds, it is attempted to make a large structure. As a result, the aluminum mold itself becomes a structure having a very large cross-sectional area.In general, it is difficult to manufacture a large aluminum mold, and moreover, the aluminum mold is highly technical for welding. After all, it is difficult and expensive to obtain a column with a large cross-sectional area using only an aluminum mold. "
It is described. As described above, although it is suggested that aluminum is used as the material of the lighting column in the above-described conventional example 2, it is actually described that it is difficult to configure the column with aluminum with a normal lighting column. Has been. Since the use of the lighting column of the present invention is limited to disaster prevention, the structure attached to the column is smaller and lighter than the normal column, and there are no cost or strength problems, and the column is made of aluminum. can do. Further, in the above-mentioned conventional example 2, there is no description or suggestion of a hybrid power generation system in which a wind power generator and a solar cell are attached to the upper part of a support.

  Furthermore, the illumination column of the present invention can enhance weather resistance and earthquake resistance by anodizing the surface of the aluminum column. Anodizing (anodizing) is a process that uses an electrolytic cell to form a layer of aluminum oxide (alumina) on the aluminum surface, and its weather resistance and strength are much higher than those of ordinary plating and coating. . Anodizing increases durability against aging and makes it maintenance-free.In addition, the surface strength is increased compared to normal aluminum, making it less prone to cracks and scratches. Is also excellent. Because it is for disaster prevention, it is meaningless if it falls down in the event of an earthquake, and earthquake resistance is an important factor. The fact that the struts are lightweight aluminum also improves earthquake resistance. Furthermore, although the surface color can be limited only by ordinary plating, the surface can be colored in an arbitrary color by adding a dye into the cavity formed in the aluminum oxide layer by anodizing. By coloring in a color according to the installation location, it can be installed without damaging the landscape. Anodizing can be performed only on aluminum, but the lighting column for disaster prevention of the present invention can be anodized because the column is made of aluminum. Although anodizing itself is known, it is usually used for protecting and coloring the aluminum surface, and is not used for increasing the strength of the entire support as in the present invention.

  In addition, the disaster prevention lighting column of the present invention uses an independent power source, and it is not necessary to draw in a power line from the outside, so that it is easier to install than a normal lighting column. By using the LED in the lighting device, the ball breakage is drastically reduced and the maintenance cost can be kept low. Furthermore, the portability can be further improved by making the support column separable. Further, by providing a switch between the battery and the LED lighting device, the lighting device can be turned on only when necessary, such as during an earthquake, and the power generation device and the battery can be further downsized. By covering the LED lighting device with a cylindrical transparent plastic, it is possible to further reduce the weight and to realize uniform illumination light at a low cost.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a disaster prevention illumination column of the present invention, and FIG. 2 is a side view of the disaster prevention illumination column of the present invention. A small wind power generator 2 and a small solar cell 3 are arranged at the top of the support column 1. The electric power generated by the small wind power generator 2 and the small solar cell 3 is stored in a battery in the control BOX 5. The LED illumination device 4 is turned on at night by the electric power stored in the battery. The height of the support column 1 is about 3.5 m, and the entire surface is made of aluminum that has been anodized. Any color can be colored at the time of anodizing (anodizing) processing, and the color can be adjusted to the surrounding landscape. The control BOX 5 can be provided with a lighting switch as necessary. The periphery of the LED lighting device 4 is covered with a cylindrical transparent plastic.

  FIG. 3 is a diagram of another embodiment. The basic configuration is the same as that of the disaster prevention lighting column in FIGS. 1 and 2, but it can be divided near the middle of the column 1. The dividing unit is provided with a wiring connector 6 that connects the upper power generation device or lighting device to the lower control BOX.

  Although not shown, the LED illumination device 4 can be swung and the illumination direction can be set to an arbitrary direction. Since the LED lighting device of the present invention is for disaster prevention, the amount of light emission is less than that of a normal lighting column lighting device. Therefore, by directing the illumination direction of the LED lighting device in an arbitrary direction, the amount of light emission can be reduced. It can cover and provide effective lighting in the event of a disaster.
