Therefore, a lighting fixture is capable of illuminating as far as an area away from the area around the root of the post 2 even while saving electric power consumption. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、屋外での夜間照明に用いられる照明装置に関する。   The present invention relates to an illumination device used for outdoor night illumination.

街路灯、庭園や構内の常夜灯などの照明装置は、適宜な照度を有する数十Wの直管蛍光燈やサークルライン等を光源とし、商用交流電源からの電力供給を受けて、3乃至4mの高さより照明するものである。従って、この種の照明装置は、極めて高い照度を有する水銀灯や低圧ナトリウム灯を光源として、5乃至10mの高さより照明する車道用のものとは用途が異なる。   Lighting devices such as street lamps, gardens and nightlights on the premises use a straight tube fluorescent lamp of several tens of watts with appropriate illuminance, a circle line, etc. as a light source, and are supplied with power from a commercial AC power source of 3 to 4 m. It illuminates from the height. Therefore, this type of illumination device has a different use from that for a roadway that illuminates from a height of 5 to 10 m using a mercury lamp or low-pressure sodium lamp having extremely high illuminance as a light source.

この種の照明装置では、3乃至4mの支柱の頂部に光源を取り付けて、その高さより斜め前方を照明し、また光源の照度を適宜に抑えることから、照明範囲が支柱の前方近傍に制約されて狭く、その上、支柱の根元付近も十分に照明することができず、足元が暗くなる傾向にあった。このため、弱視の人、子供、老人、自転車に乗っている人等は、支柱から離れた箇所や支柱の根元付近を視認し難く、路上の石、支柱、及び支柱のベース等に躓いたり衝突し易く、転倒することもあった。   In this type of lighting device, a light source is attached to the top of a 3 to 4 m post to illuminate the front obliquely from the height, and the illuminance of the light source is appropriately suppressed. Therefore, the illumination range is limited to the vicinity of the front of the post. In addition, the area around the base of the column could not be sufficiently illuminated, and the feet tended to be dark. For this reason, people with low vision, children, elderly people, people riding bicycles, etc., are difficult to see where they are away from the pillars and near the bases of the pillars. It was easy to do and sometimes fell.

そこで、例えば特許文献1には、街路灯の支柱下部に補助のランプを設け、このランプにより照明するという技術が提案されている。
特開平06−76613号公報
For this reason, for example, Patent Document 1 proposes a technique in which an auxiliary lamp is provided at the lower part of a street light column and the lamp is illuminated by this lamp.
Japanese Patent Laid-Open No. 06-76613

しかしながら、特許文献1では、支柱下部の補助のランプとして、360度方向を照明するものを用いているため、支柱付近で足元を照明するこができても、支柱から離れた箇所の照明はできなかった。また、支柱上部のランプや下部の補助のランプの照度を高くすれば、照明範囲を広げることができるものの、街路灯、庭園や構内の常夜灯などの照明装置としては、高過ぎる照度は好ましくなく、照明範囲を安易に広げることができなかった。   However, in Patent Document 1, an auxiliary lamp that illuminates in the 360-degree direction is used as an auxiliary lamp at the bottom of the support column. Therefore, even if the foot can be illuminated in the vicinity of the support column, it is possible to illuminate a place away from the support column. There wasn't. In addition, if the illuminance of the lamps at the upper part of the column and the auxiliary lamps at the lower part can be increased, the illumination range can be expanded, but as an illumination device such as a street light, a garden or a nightlight on the premises, too high illuminance is not preferable. The lighting range could not be easily expanded.

また、この種の照明装置では、商用交流電源ではなく、太陽電池と蓄電池を組み合わせた電源を用いることがある。この場合は、消費電力の節減が必須となり、照明範囲がより狭くなって、照度もより低下することになり、支柱から離れた箇所や支柱の根元付近の視認性向上が益々困難になった。   Moreover, in this kind of illuminating device, the power supply which combined the solar cell and the storage battery may be used instead of a commercial alternating current power supply. In this case, it is essential to reduce power consumption, the illumination range becomes narrower, and the illuminance also decreases, making it more difficult to improve the visibility away from the column and near the base of the column.

そこで、本発明は、上記従来の問題点に鑑みてなされたものであり、消費電力を節減しながらも、支柱の根元付近より離れた箇所までを照明することができる照明装置を提供することを目的とする。   Therefore, the present invention has been made in view of the above-described conventional problems, and provides an illuminating device that can illuminate a place far from the vicinity of the base of the column while reducing power consumption. Objective.

上記課題を解決するために、本発明の照明装置は、立設される支柱と、支柱の上部に設けられ、支柱の近辺を照明する主照明部と、支柱の下部に設けられ、照明方向に指向性を有する副照明部とを備え、指向性を有する副照明部の照明により、主照明部が照明し得ない照明範囲を照明している。   In order to solve the above-described problems, the illumination device of the present invention is provided with a support column that is erected, a main illumination unit that illuminates the vicinity of the support column, and a lower part of the support column. A sub-illumination unit having directivity, and the illumination range that cannot be illuminated by the main illumination unit is illuminated by the illumination of the sub-illumination unit having directivity.

また、本発明においては、副照明部の光源がLEDである。   Moreover, in this invention, the light source of a subillumination part is LED.

更に、本発明においては、主照明部及び副照明部の電力を生成する太陽電池を備えている。   Furthermore, in this invention, the solar cell which produces | generates the electric power of a main illumination part and a subillumination part is provided.

また、本発明においては、太陽電池は、支柱に取り付けられた枠により支持されている。   Moreover, in this invention, the solar cell is supported by the frame attached to the support | pillar.

更に、本発明においては、支柱の上部を折り曲げて、傾斜頭部及び垂直胴部を支柱に設け、主照明部を傾斜頭部及び垂直胴部に分けて配置している。   Furthermore, in the present invention, the upper part of the support is bent, the inclined head and the vertical trunk are provided on the support, and the main illumination part is divided into the inclined head and the vertical trunk.

また、本発明においては、副照明部の少なくとも一部を支柱の表面よりも突出させている。   Further, in the present invention, at least a part of the sub-illumination part is protruded from the surface of the support column.

更に、本発明においては、副照明部近傍で、支柱の表面を光反射面としている。   Furthermore, in the present invention, the surface of the support column is a light reflecting surface in the vicinity of the sub-illumination unit.

また、本発明においては、支柱は、ステンレス鋼からなる。   Moreover, in this invention, a support | pillar consists of stainless steel.

更に、本発明においては、支柱を中空構造とし、主照明部及び副照明部の電力を供給する蓄電池を支柱内に収容している。   Furthermore, in this invention, the support | pillar is made into a hollow structure and the storage battery which supplies the electric power of a main illumination part and a subillumination part is accommodated in the support | pillar.

また、本発明においては、蓄電池を主照明部と副照明部の間に配置している。   Moreover, in this invention, the storage battery is arrange | positioned between the main illumination part and the subillumination part.

更に、本発明においては、支柱の断面形状を多角形にしている。   Furthermore, in this invention, the cross-sectional shape of the support | pillar is made into the polygon.

本発明によれば、支柱上部の主照明部は、該支柱の近辺を照明しており、例えば支柱の前方近傍を照明することができる。また、支柱下部の副照明部は、主照明部が照明し得ない照明範囲を照明しており、その照明方向に指向性を有することから、例えば支柱の根元付近より離れた箇所までをも照明することができる。更に、照明方向に指向性を有することから、副照明部の照度を格別に高くしなくても、支柱の根元付近より離れた箇所までを効率的に照明して、この照明範囲の視認性を確保することができる。従って、本発明の照明装置は、街路灯、庭園や構内の常夜灯などとして好適であり、副照明部の照明を自転車や自動車を運転する人が眩しく感じることもない。また、副照明部の照明範囲を特定していることから、副照明部の消費電力を抑えることができる。従って、消費電力を節減しながらも、支柱の根元付近より離れた箇所までを照明することができる。   According to the present invention, the main illuminating unit at the top of the column illuminates the vicinity of the column, and can illuminate, for example, the vicinity of the front of the column. In addition, the sub-illumination unit at the bottom of the column illuminates the illumination range that the main illumination unit cannot illuminate, and because it has directivity in the illumination direction, for example, it illuminates even a part far from the base of the column can do. Furthermore, since it has directivity in the illumination direction, even if the illuminance of the sub-illumination part is not particularly high, it is possible to efficiently illuminate a place far from the vicinity of the base of the column, and to improve the visibility of this illumination range. Can be secured. Therefore, the lighting device of the present invention is suitable as a street light, a garden or a nightlight on the premises, etc., and a person driving a bicycle or a car does not feel dazzled by the illumination of the sub-lighting unit. Moreover, since the illumination range of the sub-illumination unit is specified, the power consumption of the sub-illumination unit can be suppressed. Therefore, it is possible to illuminate a portion far from the vicinity of the base of the column while reducing power consumption.

街路灯、庭園や構内の常夜灯などでは、主照明部の高さを3乃至4mとし、副照明部の高さを0.5乃至1.0m程度にするのが好ましい。   For street lights, gardens, night lights in the premises, etc., it is preferable that the height of the main illumination unit is 3 to 4 m and the height of the sub illumination unit is about 0.5 to 1.0 m.

仮に、副照明部の照明方向に指向性がなければ、支柱の根元付近より離れた箇所までを照明するには、副照明部の照度を極めて高くする必要があり、例えば高輝度のガス封止電球等を用いることになる。しかしながら、高輝度のガス封止電球等は、街路灯、庭園や構内の常夜灯などの副照明部として適格ではなく、副照明部として用いると、副照明部の照明を自転車や自動車を運転する人が眩しく感じてしまい、事故を誘発し易く、また消費電力も極めて増大する。   If there is no directivity in the illumination direction of the sub-illumination unit, it is necessary to increase the illuminance of the sub-illumination unit to illuminate the area far from the base of the column, for example, high-luminance gas sealing A light bulb or the like will be used. However, high-intensity gas-sealed light bulbs are not suitable as sub-lighting units for street lights, gardens, night lights, etc., and when used as sub-lighting units, the lighting of the sub-lighting unit is used by people who drive bicycles and cars. Feels dazzling, easily triggers an accident, and power consumption is extremely increased.

また、本発明によれば、副照明部の光源がLEDである。LEDは、例えば半値全幅が10度程度であり、照明方向の指向性が十分に狭く、その光が散乱せずに特定の照明範囲だけに照射される。このため、例えば雨天や霧の夜間でも、路面の状態を鮮やかに照明することができる。通常、LED1個当たりの照度が低いので、複数個(5乃至30個程度)のLEDを円や多角形のラインに沿って幾何学的に配列したものを副照明部として用いる。この場合でも、副照明部の消費電力が0.5乃至1.0W程度に過ぎない。これに対して一般の電球は、指向性を有していないので、照度を極めて高くしなければ、照明としての役目を果たせず、消費電力も極めて高くなる。   Moreover, according to this invention, the light source of a subillumination part is LED. The LED has a full width at half maximum of, for example, about 10 degrees, has a sufficiently narrow directivity in the illumination direction, and irradiates only a specific illumination range without scattering the light. For this reason, it is possible to illuminate the road surface vividly even in the rainy or foggy night. Usually, since the illuminance per LED is low, a plurality (about 5 to 30) of LEDs arranged geometrically along a circle or polygonal line is used as the sub-illumination unit. Even in this case, the power consumption of the sub-illumination unit is only about 0.5 to 1.0 W. On the other hand, since a general light bulb does not have directivity, unless the illuminance is extremely high, it cannot serve as illumination and the power consumption becomes extremely high.

更に、本発明によれば、主照明部及び副照明部の電力を生成する太陽電池を備えている。この場合は、太陽電池の発電電力を蓄電池に一旦充電して、夜間に蓄電池からの電力供給により主照明部及び副照明部を点灯させることになる。従って、商用交流電源からの電力供給を必用とせず、地震等の災害時に商用交流電源からの電力供給が停止しても、主照明部及び副照明部を点灯させることができ、非常灯としても役立てることができる。   Furthermore, according to this invention, the solar cell which produces | generates the electric power of a main illumination part and a subillumination part is provided. In this case, the power generated by the solar battery is once charged in the storage battery, and the main illumination unit and the sub-illumination unit are turned on by supplying power from the storage battery at night. Therefore, power supply from the commercial AC power supply is not required, and even if the power supply from the commercial AC power supply stops in the event of a disaster such as an earthquake, the main illumination unit and the sub-illumination unit can be turned on, and as an emergency light Can be useful.

しかも、主照明部及び副照明部を直流で駆動し、蛍光燈の様に交流駆動を必要としないので、各種の無線機、携帯電話機、心臓病のペースメーカ等に影響を与えることがない。   In addition, the main illumination unit and the sub-illumination unit are driven with a direct current, and no alternating current drive is required like a fluorescent lamp, so that it does not affect various radio devices, mobile phones, heart disease pacemakers, and the like.

また、本発明によれば、太陽電池を支柱に取り付けられた枠により支持しているので、太陽電池そのものを支持する枠と太陽電池を支柱に取り付けるための枠を共通化することができ、枠の小型化、構造の簡単化、外観の改善、部品点数の減少、コストの削減等を図ることができる。また、太陽電池並びに枠の受風面積を減らして、それらの必要強度を小さくすることができ、これに伴い枠の厚みや質量をより軽減することができ、支柱の厚みや質量も軽減することができる。   According to the present invention, since the solar cell is supported by the frame attached to the support column, the frame for supporting the solar cell itself and the frame for attaching the solar cell to the support column can be shared. Can be reduced, the structure can be simplified, the appearance can be improved, the number of parts can be reduced, and the cost can be reduced. In addition, the solar cell and the wind receiving area of the frame can be reduced to reduce their required strength, and accordingly the thickness and mass of the frame can be further reduced, and the thickness and mass of the column can also be reduced. Can do.

更に、本発明によれば、支柱の上部を折り曲げて、傾斜頭部及び垂直胴部を支柱に設け、主照明部を傾斜頭部及び垂直胴部に分けて配置している。これにより、主照明部を広い範囲に分散配置することができ、主照明部による照明範囲を多様に設定することが可能になり、しかも優れた外観を得ることができる。   Further, according to the present invention, the upper portion of the support is bent, the inclined head and the vertical trunk are provided on the support, and the main illumination unit is divided into the inclined head and the vertical trunk. As a result, the main illumination units can be distributed over a wide range, the illumination range of the main illumination unit can be set in various ways, and an excellent appearance can be obtained.

街路灯、庭園や構内の常夜灯などでは、傾斜頭部の傾斜角を水平に対して20乃至30度に設定し、主照明部の光を傾斜頭部の傾斜角に直交する方向に照射し、また主照明部の光を垂直胴部より斜め下方45度の方向に照射するのが好ましい。   For street lamps, night lights in gardens and premises, etc., the tilt angle of the tilted head is set to 20 to 30 degrees with respect to the horizontal, and the light of the main illumination unit is irradiated in a direction orthogonal to the tilt angle of the tilted head. Moreover, it is preferable to irradiate the light of a main illumination part in the direction of 45 degree | times diagonally downward from a vertical trunk | drum.

また、本発明によれば、副照明部の少なくとも一部を支柱の表面よりも突出させているので、副照明部からの僅かな散乱光が支柱の表面で反射して、足元が照明される。この場合は、副照明部近傍で、支柱の表面を光反射面とし、支柱の表面での光反射率を高めるのが好ましい。   Further, according to the present invention, since at least a part of the sub-illuminating unit protrudes from the surface of the support column, a slight amount of scattered light from the sub-illuminating unit is reflected by the surface of the support column and the foot is illuminated. . In this case, it is preferable to increase the light reflectivity on the surface of the support column in the vicinity of the sub-illumination unit by using the surface of the support column as a light reflection surface.

更に、支柱として、ステンレス鋼製のものを用いているので、支柱の表面全体の光反射率を高めることができ、副照明部からの僅かな散乱光だけではなく、主照明部からの僅かな散乱光をも支柱の表面で反射することができ、支柱そのものが照明され、支柱の視認性が向上し、外観が良くなる。また、支柱の耐久性が極めて高くなって、塗装が不用となり、噴水池や湿地帯での長期使用が可能になる。   Furthermore, because the support made of stainless steel is used, the light reflectivity of the entire surface of the support can be increased, and not only a slight amount of scattered light from the sub-illumination unit but also a slight amount from the main illumination unit. Scattered light can also be reflected from the surface of the column, and the column itself is illuminated, improving the visibility of the column and improving the appearance. In addition, the durability of the support becomes extremely high, so that painting is unnecessary, and long-term use in a fountain and a wetland is possible.

また、本発明によれば、支柱を中空構造とし、主照明部及び副照明部の電力を供給する蓄電池を支柱内に収容している。例えば、蓄電池を主照明部と副照明部の間に配置している。このため、複数の蓄電池を重ねて収容することができ、各蓄電池と太陽電池との組み合わせからなる電源により、日照時間が殆ど無くても、数日にわたって、主照明部及び副照明部を点灯させることが可能になる。このため、単なる照明としてだけではなく、案内灯、保安灯、地震等の災害時の非常灯などの役目も果たすことができる。   Moreover, according to this invention, the support | pillar is made into a hollow structure and the storage battery which supplies the electric power of a main illumination part and a subillumination part is accommodated in the support | pillar. For example, the storage battery is disposed between the main illumination unit and the sub illumination unit. For this reason, a plurality of storage batteries can be accommodated in a stacked manner, and the main illumination unit and the sub-illumination unit are turned on for several days with almost no sunshine hours by a power source composed of a combination of each storage battery and a solar cell. It becomes possible. For this reason, it can serve not only as illumination but also as a guide light, a security light, an emergency light in the event of a disaster such as an earthquake.

更に、支柱の断面形状を多角形にしている。この場合は、地面に穴を掘って、この穴に支柱を立て、コンクリートを流し込んで固めるだけで、支柱を回転させない状態で立設することができる。   Furthermore, the cross-sectional shape of the column is a polygon. In this case, the pillar can be erected in a state where the pillar is not rotated by simply digging a hole in the ground, standing a pillar in the hole, pouring concrete into the hole, and hardening the concrete.

The length of the vertical body 2b is set to 3.0 m for the base plate type and 4.0 m for the embedded type, and the length from the upper end of the vertical body 2b to the base plate 11 is 3 m. 0.0 m.

主照明部3は、ベースプレート11から略3m(地上略3m)の高さに設けられ、傾斜頭部2a側の6個のLEDランプ21と、垂直胴部2b側の2個のLEDランプ22とを備える。各LEDランプ21、22は、同一構造であり、図6に示す様に18個のLED23を基板24上で円や多角形のラインに沿って幾何学的に配列し、各LED23及び基板24を散光球体25により覆い、散光球体25の開口端25aに口金26を固定したものである。各LED23は、基板24の配線パターンにより相互に接続され、更に基板24を介して口金26に接続されている。散光球体25は、例えばガラス球体の表面に散光性粒子を塗布したものであり、各LED23からの光を散乱させる。各LED23は、例えば半値全幅が10度程度であり、照明方向の指向性が十分に狭いものの、それらの光が散光球体25により散乱される。このため、各LEDランプ21、22としての指向性は広くなる。   The main illumination unit 3 is provided at a height of approximately 3 m (approximately 3 m above the ground) from the base plate 11, and includes six LED lamps 21 on the inclined head 2 a side and two LED lamps 22 on the vertical trunk 2 b side. Is provided. Each of the LED lamps 21 and 22 has the same structure, and as shown in FIG. 6, 18 LEDs 23 are geometrically arranged on a substrate 24 along a circle or a polygonal line, and each LED 23 and the substrate 24 are arranged. It is covered with a light scattering sphere 25, and a base 26 is fixed to the opening end 25 a of the light scattering sphere 25. The LEDs 23 are connected to each other by the wiring pattern of the substrate 24 and further connected to the base 26 via the substrate 24. The light scattering sphere 25 is, for example, a surface of a glass sphere coated with light scattering particles, and scatters light from each LED 23. Each LED 23 has a full width at half maximum of, for example, about 10 degrees, and the directivity in the illumination direction is sufficiently narrow, but those lights are scattered by the diffuser sphere 25. For this reason, the directivity as each LED lamp 21 and 22 becomes wide.

支柱2の傾斜頭部2aの下側壁板2cに6つの円形の孔27を設け、各孔27の奥にそれぞれのソケット28を配列し固定している。各LEDランプ21を各孔27に通して、各LEDランプ21の口金26をそれぞれのソケット28に差し込んで接続し、各LEDランプ21の全てのLED23を各ソケット28に接続する。   Six circular holes 27 are provided in the lower side wall plate 2 c of the inclined head 2 a of the support column 2, and the sockets 28 are arranged and fixed behind the holes 27. Each LED lamp 21 is passed through each hole 27, and a base 26 of each LED lamp 21 is inserted and connected to each socket 28, and all LEDs 23 of each LED lamp 21 are connected to each socket 28.

この状態では、各LEDランプ21は、20乃至30度で傾斜している傾斜頭部2aに対して直交する方向に向き、支柱2の前方近傍に向く。また、各LEDランプ21の指向性は広い。このため、各LEDランプ21は、図4及び図5に示す様な支柱2の前方近傍の照明範囲Aを照明する。この照明範囲Aは、例えば直径2m程度である。   In this state, each LED lamp 21 is directed in a direction orthogonal to the inclined head 2 a inclined at 20 to 30 degrees, and is directed to the vicinity of the front of the column 2. Moreover, the directivity of each LED lamp 21 is wide. For this reason, each LED lamp 21 illuminates an illumination range A in the vicinity of the front side of the column 2 as shown in FIGS. 4 and 5. This illumination range A is about 2 m in diameter, for example.

また、垂直胴部2bの前側壁板2dの上側に1つの長円形の孔31を設け、孔31の奥に2つのソケット32を配置し固定している。各LEDランプ22を孔31に通して、各LEDランプ22の口金26をそれぞれのソケット32に差し込んで接続し、各LEDランプ22の全てのLED23を各ソケット32に接続する。   Further, one oval hole 31 is provided on the upper side of the front side wall plate 2d of the vertical body 2b, and two sockets 32 are arranged and fixed in the back of the hole 31. The LED lamps 22 are passed through the holes 31, and the caps 26 of the LED lamps 22 are inserted and connected to the sockets 32, and all the LEDs 23 of the LED lamps 22 are connected to the sockets 32.

この状態では、各LEDランプ22は、垂直胴部2bより斜め下方45度の方向に向き、支柱2の前方少し遠くに向く。また、各LEDランプ22の指向性は、各LED21と同様に広い。このため、各LEDランプ22は、図4及び図5に示す様な支柱2の前方少し離れた照明範囲Bを照明する。この照明範囲Bは、例えば長さ3m程度である。   In this state, each LED lamp 22 is directed in the direction of 45 degrees obliquely downward from the vertical body portion 2b, and slightly forward of the support column 2. Moreover, the directivity of each LED lamp 22 is as wide as that of each LED 21. For this reason, each LED lamp 22 illuminates an illumination range B slightly away from the front of the column 2 as shown in FIGS. 4 and 5. This illumination range B is about 3 m in length, for example.

従って、主照明部3は、その照明方向の指向性が広く、図4及び図5に示す支柱2の前方近傍の照明範囲A及び前方少し離れた照明範囲Bを照明する。   Therefore, the main illumination unit 3 has a wide directivity in the illumination direction, and illuminates the illumination range A in the vicinity of the front of the column 2 shown in FIGS. 4 and 5 and the illumination range B slightly away from the front.

副照明部4は、ベースプレート11より略0.5m(地上略0.5m)の垂直胴部2bの部位に設けられた2個のLEDランプ33を備える。各LEDランプ33は、各LEDランプ21、22と略同一構造であり、図7に示す様に9個のLED23を基板24上で円や多角形のラインに沿って幾何学的に配列し、各LED23及び基板24を透明球体29により覆い、透明球体29の開口端29aに口金26を固定したものである。各LED23は、基板24の配線パターンにより相互に接続され、更に基板24を介して口金26に接続されている。透明球体29は、各LEDランプ21、22の散光球体25とは異なり、例えば単なる透明なガラス球体であり、各LED23からの光をそのまま透過させる。従って、LEDランプ33の指向性は、各LED23の指向性に略一致し、例えば半値全幅が10度程度で十分に狭く、その照射範囲も狭くなる。   The sub-illumination unit 4 includes two LED lamps 33 provided at a portion of the vertical body portion 2 b that is approximately 0.5 m (approximately 0.5 m above the ground) from the base plate 11. Each LED lamp 33 has substantially the same structure as each LED lamp 21, 22, and as shown in FIG. 7, nine LEDs 23 are geometrically arranged on a substrate 24 along a circle or polygonal line, Each LED 23 and substrate 24 are covered with a transparent sphere 29, and a base 26 is fixed to an open end 29 a of the transparent sphere 29. The LEDs 23 are connected to each other by the wiring pattern of the substrate 24 and further connected to the base 26 via the substrate 24. The transparent sphere 29 is different from the diffuse sphere 25 of the LED lamps 21 and 22, for example, is simply a transparent glass sphere, and transmits light from the LEDs 23 as it is. Therefore, the directivity of the LED lamp 33 substantially matches the directivity of each LED 23, and for example, the full width at half maximum is about 10 degrees and is sufficiently narrow, and the irradiation range is also narrowed.

垂直胴部2bの前側壁板2dの下側に2つ長円形の孔34を設け、各孔34の奥にそれぞれのソケット35を配置し固定している。各LEDランプ33を各孔34に通して、各LEDランプ33の口金26をそれぞれのソケット35に差し込んで接続し、各LEDランプ33の全てのLED23を各ソケット35に接続する。   Two oblong holes 34 are provided on the lower side of the front side wall plate 2d of the vertical body 2b, and sockets 35 are arranged and fixed at the back of each hole 34, respectively. The LED lamps 33 are passed through the holes 34, and the caps 26 of the LED lamps 33 are inserted and connected to the sockets 35, and all the LEDs 23 of the LED lamps 33 are connected to the sockets 35.

この状態では、各LEDランプ33は、垂直胴部2bより斜め下方10度の方向に向き、支柱2の前方遠くに向く。また、各LEDランプ33の指向性は、狭い。このため、各LEDランプ33は、支柱2の前方遠くを照明する。   In this state, each LED lamp 33 is directed in the direction of 10 degrees obliquely downward from the vertical body portion 2 b and is directed farther forward of the column 2. Moreover, the directivity of each LED lamp 33 is narrow. For this reason, each LED lamp 33 illuminates the far front of the column 2.

更に、各LEDランプ33は、図8に示す様に垂直胴部2bの前側壁板2dの各孔34から僅かに突出している。このため、各LEDランプ33の透明球体29で反射されたり、更に前側壁板2dの表面で反射された僅かな散乱光が支柱2の根元近傍を照明する。   Furthermore, each LED lamp 33 slightly protrudes from each hole 34 of the front side wall plate 2d of the vertical body 2b as shown in FIG. For this reason, the slight scattered light reflected by the transparent sphere 29 of each LED lamp 33 and further reflected by the surface of the front side wall plate 2 d illuminates the vicinity of the base of the support column 2.

従って、各LEDランプ33により支柱2の前方遠くが直接照明され、各LEDランプ33の散乱光により支柱2の根元付近が間接照明される。すなわち、副照明部4は、図4及び図5に示す様な支柱2の根元付近から前方離れた箇所までの照明範囲Cを照明する。この照明範囲Cは、例えば最大幅2mで長さ10m程度である。   Accordingly, each LED lamp 33 directly illuminates the far front of the column 2, and the scattered light of each LED lamp 33 indirectly illuminates the vicinity of the base of the column 2. That is, the sub-illumination unit 4 illuminates the illumination range C from the vicinity of the base of the support column 2 to the location far from the front as shown in FIGS. 4 and 5. The illumination range C has a maximum width of 2 m and a length of about 10 m, for example.

尚、各LEDランプ33だけではなく、各LEDランプ21、22も支柱2の各孔27、31から僅かに突出しており、各LEDランプ21、22の僅かな散乱光が支柱2の表面で反射される。これにより、支柱2そのものが照明され、支柱2の視認性が向上し、外観が良くなる。   Not only the LED lamps 33 but also the LED lamps 21 and 22 slightly protrude from the holes 27 and 31 of the support column 2, and the slight scattered light of the LED lamps 21 and 22 is reflected by the surface of the support column 2. Is done. Thereby, the support | pillar 2 itself is illuminated, the visibility of the support | pillar 2 improves, and an external appearance improves.

また、副照明部4の各LEDランプ33の傾きをずらして、各LEDランプ33により図4及び図5に示す照明範囲Cを直接照明することもできる。   Moreover, the illumination range C shown in FIG.4 and FIG.5 can also be directly illuminated by each LED lamp 33, shifting the inclination of each LED lamp 33 of the sub illumination part 4. FIG.

この様に照明装置1では、主照明部3により図4及び図5に示す支柱2の前方近傍の照明範囲A及び前方少し離れた照明範囲Bを照明するだけではなく、副照明部4により図4及び図5に示す支柱2の根元付近から前方離れた箇所までの照明範囲Cを照明することができる。このため、例えば図9に示す様に照明装置1を庭園等に設置した場合は、照明装置1の支柱2の前方付近は勿論のこと、支柱2の根元付近より飛び石36からなる路に沿って照明をすることができる。あるいは、照明装置1を街路灯として設置した場合は、支柱2の根元付近より街路に沿って照明をすることができる。   Thus, in the illuminating device 1, the main illumination unit 3 not only illuminates the illumination range A in the vicinity of the front of the column 2 and the illumination range B slightly away from the front shown in FIG. 4 and FIG. 4 and the illumination range C from the vicinity of the base of the support 2 shown in FIG. For this reason, for example, as shown in FIG. 9, when the lighting device 1 is installed in a garden or the like, not only near the front of the column 2 of the lighting device 1, but also along the path made of the stepping stones 36 from the vicinity of the base of the column 2. Can be illuminated. Or when the illuminating device 1 is installed as a street light, it can illuminate along a street from the base vicinity of the support | pillar 2.

また、副照明部4が2個のLEDランプ33だけであり、各LEDランプ33の照度が格別に高くないものの、各LEDランプ33の照明方向に指向性を有することから、支柱2の根元付近より離れた箇所までを効率的に照明して、この照明範囲の視認性を確保することができる。従って、照明装置1は、街路灯、庭園や構内の常夜灯などとして好適であり、副照明部4の照明を自転車や自動車を運転する人が眩しく感じることもない。また、副照明部4の照明範囲を特定していることから、副照明部4の消費電力を抑えることができる。従って、消費電力を節減しながらも、支柱2の根元付近より離れた箇所までを照明することができる。   Moreover, although the sub illumination part 4 is only two LED lamps 33 and the illumination intensity of each LED lamp 33 is not especially high, since it has directivity in the illumination direction of each LED lamp 33, it is near the base of the support | pillar 2 It is possible to efficiently illuminate more distant places and ensure the visibility of this illumination range. Therefore, the illuminating device 1 is suitable as a street light, a night light in a garden or a premises, etc., and a person driving a bicycle or a car does not feel the illumination of the sub-illumination unit 4 dazzling. Moreover, since the illumination range of the sub illumination unit 4 is specified, the power consumption of the sub illumination unit 4 can be suppressed. Therefore, it is possible to illuminate a portion far from the vicinity of the base of the support column 2 while reducing power consumption.

仮に、副照明部4の照明方向に指向性がなければ、支柱2の根元付近より離れた箇所までを照明するには、副照明部4の照度を極めて高くする必要があり、例えば高輝度のガス封止電球等を用いることになる。しかしながら、高輝度のガス封止電球等は、街路灯、庭園や構内の常夜灯などの副照明部4として適格ではなく、副照明部4として用いると、副照明部4の照明を自転車や自動車を運転する人が眩しく感じてしまい、事故を誘発し易く、また消費電力も極めて増大する。   If there is no directivity in the illumination direction of the sub-illumination unit 4, in order to illuminate a place far from the vicinity of the base of the support column 2, the illuminance of the sub-illumination unit 4 needs to be extremely high. A gas sealed bulb or the like is used. However, a high-intensity gas-sealed light bulb is not suitable as the sub-illumination unit 4 such as a street light, a garden or a nightlight on the premises, and when used as the sub-illumination unit 4, the illumination of the sub-illumination unit 4 is used for a bicycle or a car. The driver feels dazzling, easily triggers an accident, and the power consumption is extremely increased.

更に、先に述べた様に主照明部3の各LEDランプ21、22が18個のLED23をそれぞれ備え、主照明部3の消費電力が数W程度であり、また副照明部4の各LEDランプ33が9個のLED23をそれぞれ備え、副照明部4の消費電力が0.5乃至1.0W程度であることから、消費電力を低減することができる。このため、各蓄電池6として、2乃至6個の12V長寿命蓄電池を適用すれば、太陽電池5と各蓄電池6との組み合わせからなる電源により、日照時間が殆ど無くても、5乃至10日にわたって、主照明部3及び副照明部4を点灯させることが可能になる。このため、照明装置1は、単なる照明としてだけではなく、案内灯、保安灯、地震等の災害時の非常灯などの役目も果たすことができる。   Further, as described above, the LED lamps 21 and 22 of the main illumination unit 3 are each provided with 18 LEDs 23, the power consumption of the main illumination unit 3 is about several W, and the LEDs of the sub illumination unit 4 Since the lamp 33 includes each of the nine LEDs 23 and the power consumption of the sub-illumination unit 4 is about 0.5 to 1.0 W, the power consumption can be reduced. For this reason, if 2 to 6 12V long-life storage batteries are applied as each storage battery 6, the power source composed of a combination of the solar battery 5 and each storage battery 6 can be used for 5 to 10 days even if there is almost no sunshine time. The main illumination unit 3 and the sub illumination unit 4 can be turned on. For this reason, the illuminating device 1 can serve not only as illumination but also as a guide light, a security light, an emergency light in the event of a disaster such as an earthquake.

また、各LEDランプ21、22、33においては、複数のLEDを幾何学的に配置しているので、各LEDの発光そのものがデザイン的に優れ、人に安らぎ感を与える。   Moreover, in each LED lamp 21, 22, 33, since several LED is geometrically arrange | positioned, the light emission itself of each LED is excellent in design, and gives a feeling of comfort to a person.

次に、太陽電池5、各蓄電池6、及び充放電ユニット7について述べる。   Next, the solar cell 5, each storage battery 6, and the charge / discharge unit 7 will be described.

太陽電池5は、支持枠41により支持されており、この支持枠41が支柱2の垂直胴部2b上端に突設されたシャフト42により回転自在に支持されている。図10は、太陽電池5、支持枠41、及びシャフト42等を示す断面図である。太陽電池5は、20乃至30年の耐用期間を持つものであり、例えば単結晶又は多結晶の太陽電池セルを太陽光透過率の高い強化ガラス裏面に実装支持し、耐候性白色フィルムを貼り合わせて、EVA(エチレン酢酸ビニル共重合体)やシリコーン樹脂等により補強し、更にコネクタボックス5aを取り付けたものである。支持枠41は、ステンレス鋼を板金加工して形成されたものであり、太陽電池5の縁を引っ掛けて支持している。また、支持枠41の中央部が下方に膨らんで中空となっており、太陽電池5並びに支持枠41の構造強度を増すと共に、デザイン的にも変化を設けている。ここに太陽電池5のコネクタボックス5aが収納されている。更に、支持枠41裏面には、太陽電池5の受光面に対して70度〜45度傾けて筒状のシャフト受け43を突設している。   The solar cell 5 is supported by a support frame 41, and the support frame 41 is rotatably supported by a shaft 42 that protrudes from the upper end of the vertical trunk portion 2 b of the column 2. FIG. 10 is a cross-sectional view showing the solar cell 5, the support frame 41, the shaft 42, and the like. The solar cell 5 has a lifetime of 20 to 30 years. For example, a single-crystal or polycrystalline solar cell is mounted and supported on the back side of a tempered glass having high sunlight transmittance, and a weather-resistant white film is bonded thereto. These are reinforced with EVA (ethylene vinyl acetate copolymer), silicone resin, or the like, and further attached with a connector box 5a. The support frame 41 is formed by sheet metal processing of stainless steel, and supports the edge of the solar cell 5 by hooking it. Further, the central portion of the support frame 41 bulges downward and becomes hollow, and the structural strength of the solar cell 5 and the support frame 41 is increased, and design changes are also provided. The connector box 5a of the solar cell 5 is accommodated here. Further, a cylindrical shaft receiver 43 is provided on the back surface of the support frame 41 so as to be inclined by 70 to 45 degrees with respect to the light receiving surface of the solar cell 5.

支持枠41は、その裏面のシャフト受け43を支柱2の垂直胴部2b上端のシャフト42に嵌め込むことにより回転自在に支持される。受光面に対して70度の状態では、太陽電池5の受光面が水平方向に対して20度傾く。この20度の傾きは、山影、至近の建物、構造物等により受光障害が多く発生するなど照明装置1の設置環境が悪く、太陽からの直接光が支柱2の上部の太陽電池5に殆ど入射しないときに、この直接光に代わって、空からの間接光を太陽電池5により多く入射させるために設定される。   The support frame 41 is rotatably supported by fitting the shaft receiver 43 on the back surface thereof to the shaft 42 at the upper end of the vertical trunk portion 2 b of the column 2. In a state of 70 degrees with respect to the light receiving surface, the light receiving surface of the solar cell 5 is inclined 20 degrees with respect to the horizontal direction. The inclination of 20 degrees is poor in the installation environment of the lighting device 1 such as a lot of light receiving obstacles caused by mountain shadows, nearby buildings, structures, etc., and direct light from the sun is almost incident on the solar cell 5 above the support column 2. When not, it is set so that more indirect light from the sky enters the solar cell 5 in place of the direct light.

また、照明装置1の設置環境が良く、太陽からの直接光が支柱2上部の太陽電池5に入射するときには、太陽電池5の受光面を水平方向に対して略35度傾けるのが良い。   Moreover, when the installation environment of the illuminating device 1 is good and the direct light from the sun is incident on the solar cell 5 above the support column 2, the light receiving surface of the solar cell 5 is preferably inclined approximately 35 degrees with respect to the horizontal direction.

冬季多少の積雪がある地域、及び年間を通して12月1月等の日射量が極端に少ない地域などでは、積雪の滑雪効果も増大する略45度傾けるのが良い。   In areas where there is a little snow in the winter season and areas where the amount of solar radiation is extremely low, such as December and throughout the year, it is better to tilt approximately 45 degrees to increase the snow sliding effect.

更に、支持枠41を回転させて、太陽電池5による発電電力が最も大きくなる様に太陽電池5を南の方向近辺に向ける。   Further, the support frame 41 is rotated so that the solar cell 5 is directed in the vicinity of the south direction so that the power generated by the solar cell 5 is maximized.

支柱2の背面側には、着脱自在の背面板2eをネジ止めしている。背面板2eの長さは、各蓄電池6及び充放電ユニット7の配置スペースの長さに略等しくされており、この背面板2eを取り外せば、各蓄電池6及び充放電ユニット7のメンテナンスを行なうことができる。   A detachable back plate 2 e is screwed to the back side of the column 2. The length of the back plate 2e is substantially equal to the length of the arrangement space of each storage battery 6 and the charging / discharging unit 7. If this back plate 2e is removed, the maintenance of each storage battery 6 and the charging / discharging unit 7 is performed. Can do.

また、支柱2の内壁の4隅と各蓄電池6及び充放電ユニット7との間には、隙間を設けている。この隙間は、夏期に支柱2内で温度上昇した空気や、各蓄電池6から発生したガスを上方に通して支柱2の各LEDランプの孔から放出するために、あるいは支柱2内に侵入した雨水や結露を下方に通して支柱2の水抜き孔(図示せず)から排水するために設けられたものである。   Further, gaps are provided between the four corners of the inner wall of the support column 2 and each of the storage batteries 6 and the charge / discharge unit 7. This gap is used to discharge air that has risen in the support column 2 in the summer and gas generated from each storage battery 6 through the LED lamp holes of the support column 2 or rainwater that has entered the support column 2. And is provided for draining water from a drain hole (not shown) of the support column 2 through the condensation downward.

ここで、太陽電池5の発電電力は、充放電ユニット7に供給される。充放電ユニット7は、太陽電池5の発電電力を各蓄電池6に充電する。また、日没後には、太陽電池5の発電電圧が低下することから、充放電ユニット7は、太陽電池5の発電電圧が一定値以下となる日没を感知し、各蓄電池6の電力を主照明部3及び副照明部4に供給して、主照明部3及び副照明部4を点灯させる。更に、充放電ユニット7は、主照明部3及び副照明部4の点灯時間を計時し、設定されたこの点灯時間が一定時間に達すると、主照明部3及び副照明部4を消灯する。これは、一般に、深夜になると照明を必要としないことから、節電のために行われる。ただし、照明装置1の保安灯や非常灯としての役目を重視する場合は、明け方近くまで、蓄電池5の残存電力が一定値を下回らない範囲で、主照明部3及び副照明部4の点灯を継続しても良い。   Here, the generated power of the solar cell 5 is supplied to the charge / discharge unit 7. The charge / discharge unit 7 charges each storage battery 6 with the generated power of the solar battery 5. Moreover, since the power generation voltage of the solar cell 5 decreases after sunset, the charging / discharging unit 7 senses sunset when the power generation voltage of the solar cell 5 becomes a certain value or less, and mainly uses the power of each storage battery 6. Supplying to the illumination unit 3 and the sub-illumination unit 4, the main illumination unit 3 and the sub-illumination unit 4 are turned on. Further, the charging / discharging unit 7 measures the lighting time of the main lighting unit 3 and the sub lighting unit 4 and turns off the main lighting unit 3 and the sub lighting unit 4 when the set lighting time reaches a certain time. This is generally done to save power because no lighting is required at midnight. However, when the role of the lighting device 1 as a safety light or emergency light is emphasized, the main lighting unit 3 and the sub-lighting unit 4 are turned on until the remaining power of the storage battery 5 does not fall below a certain value until dawn. You may continue.

この点灯時間は1〜10時間の任意の時間に設定でき、日没から日の出までと設定することもできる。   This lighting time can be set to any time from 1 to 10 hours, and can also be set from sunset to sunrise.

この様に照明装置1では、太陽電池5を支持枠41により直接支持しているので、太陽電池5そのものを支持する枠と太陽電池5を支柱2に取り付けるための枠を共通化することができ、支持枠41の小型化、構造の簡単化、外観の改善、部品点数の減少、コストの削減等を図ることができる。また、太陽電池5並びに支持枠41の受風面積を減らして、それらの必要強度を小さくすることができ、これに伴い支持枠41の厚みや質量をより軽減することができ、支柱2の厚みや質量も軽減することができる。   Thus, in the illuminating device 1, since the solar cell 5 is directly supported by the support frame 41, the frame for supporting the solar cell 5 itself and the frame for attaching the solar cell 5 to the support column 2 can be shared. The support frame 41 can be reduced in size, simplified in structure, improved in appearance, reduced in the number of parts, reduced in cost, and the like. Moreover, the wind receiving area of the solar cell 5 and the support frame 41 can be reduced to reduce the necessary strength thereof, and accordingly, the thickness and mass of the support frame 41 can be further reduced, and the thickness of the support column 2 can be reduced. And mass can be reduced.

通常、市販されている太陽電池には、厚み25乃至50mm程度のアルミ製の枠が取り付けられている。仮に、このアルミ製の枠を更に支柱2の支持枠41により支持するという二重構造を採用したならば、大型化、構造の複雑化、外観の劣悪化、部品点数の増大、コストの増大等を招く。また、太陽電池並びに枠の受風面積が増大するので、それらの強度や支柱の強度を増大させる必要がある。   Usually, a commercially available solar cell is provided with an aluminum frame having a thickness of about 25 to 50 mm. If a double structure in which this aluminum frame is further supported by the support frame 41 of the support column 2 is adopted, the size, the structure becomes complicated, the appearance deteriorates, the number of parts increases, the cost increases, etc. Invite. Moreover, since the wind receiving area of a solar cell and a frame increases, it is necessary to increase the intensity | strength of those and the intensity | strength of a support | pillar.

また、太陽電池5と各蓄電池6との組み合わせからなる電源を採用しているので、商用交流電源からの電力供給を必用とせず、地震等の災害時に商用交流電源からの電力供給が停止しても、主照明部及び副照明部を点灯させることができ、非常灯として役立てることができる。更に、商用交流電源と接続するための配線工事を必要とせず、太陽電池5の発電が可能であれば、如何なる場所にも設置することができる。   Moreover, since the power supply which consists of the combination of the solar cell 5 and each storage battery 6 is adopted, the power supply from a commercial AC power supply stops at the time of disasters, such as an earthquake, without requiring the power supply from a commercial AC power supply. In addition, the main illumination unit and the sub-illumination unit can be turned on, which can be used as an emergency light. Furthermore, the wiring work for connecting with a commercial AC power supply is not required, and the solar battery 5 can be installed in any place as long as the power generation is possible.

更に、四角柱状の中空の支柱2内で、主照明部3と副照明部4間に各蓄電池6及び充放電ユニット7を縦に並べて収容しているので、支柱2内のスペースを有効利用することができる。   Furthermore, since each storage battery 6 and the charge / discharge unit 7 are accommodated vertically between the main illumination unit 3 and the sub-illumination unit 4 in the rectangular column-shaped hollow column 2, the space in the column 2 is effectively used. be able to.

In this state, since the support column 2 is formed by sheet metal processing of a stainless steel plate having a thickness of 2 mm, the weight of the illuminating device 1 is about 60 Kg and can be easily carried in manually by about two workers. And installation becomes possible.

支柱2の前面板を着脱するものも製作し、同効果を確認しており、前面板のものも可能。   The thing which attaches and detaches the front plate of the support 2 is also manufactured, and the same effect has been confirmed.

また、照明装置1の設置箇所に、深さ1m余りの穴を掘り、穴の底面に割石や栗石等を敷設する。そして、支柱2を穴に入れ、補助のつっかい棒等を用いて、支柱2を立て、コンクリートを穴に流し込み、コンクリートの表面を支柱2のベースプレート11の位置と略同一高さになる様に均す。この状態で、コンクリートを固めてから、補助のつっかい棒等を除去する。   In addition, a hole with a depth of about 1 m is dug in the place where the lighting device 1 is installed, and quarry stone, chestnut stone, or the like is laid on the bottom surface of the hole. Then, the support column 2 is put in the hole, and the support column 2 is erected using an auxiliary stick or the like, and the concrete is poured into the hole so that the surface of the concrete becomes substantially the same height as the position of the base plate 11 of the support column 2. Equalize. In this state, after the concrete is hardened, the auxiliary sticks are removed.

更に、各蓄電池6及び充放電ユニット7を支柱2内に収容して、配線を接続し、背面板2eを支柱2の背面に取り付けてネジ止めする。   Furthermore, each storage battery 6 and the charging / discharging unit 7 are accommodated in the support | pillar 2, a wiring is connected, the back plate 2e is attached to the back surface of the support | pillar 2, and is screwed.

従って、クレーン車や掘削車等の建設重機を必用とせず、2名程度の作業者だけで、照明装置1を設置することができる。また、建設重機の侵入が不可能な道路の無い区域や急斜面の区域であっても、照明装置1の設置が可能である。更に、設置作業中の通行規制やガードマンの配置等が不用である。   Therefore, construction equipment such as a crane truck or excavator is not required, and the lighting device 1 can be installed by only about two workers. In addition, the lighting device 1 can be installed even in an area where there is no road or a steep slope where heavy construction equipment cannot enter. Furthermore, traffic restrictions during installation work, placement of guardmen, etc. are unnecessary.

また、支柱2が四角柱状であるから、固まったコンクリートにより支柱2の台風又は強風などによる回転が禁止される。このため、支柱2の回転を止めるための格別な構造を必用としない。   Moreover, since the support | pillar 2 is square pillar shape, the rotation by the typhoon or the strong wind etc. of the support | pillar 2 is prohibited by the solidified concrete. For this reason, the special structure for stopping rotation of the support | pillar 2 is not required.

尚、本発明は、上記実施例に限定されるものではなく、多様に変形することができる。例えば、各LEDランプの個数や配置、及びLEDランプの各LEDの個数や配置を適宜に変更しても良い。また、主照明部3及び副照明部4の照明方向を適宜に変更したり調節可能な構造を採用しても構わない。更に、主照明部3として、LEDランプの代わりに、多の種類の光源を採用しても良い。あるいは、副照明部4として、LEDランプの代わりに、他の種類の光源と反射板等の組み合わせを採用して、副照明部4に指向性を持たせても構わない。また、主照明部3及び副照明部4の照射光の色を相互に異ならせても良い。   In addition, this invention is not limited to the said Example, It can deform | transform variously. For example, the number and arrangement of the LED lamps and the number and arrangement of the LEDs of the LED lamp may be appropriately changed.
