Description

【０００１】
【発明の属する技術分野】
この発明は、避難誘導表示用照明器具等の表示灯に関するものである。
【０００２】
【従来の技術】
従来、災害灯による停電時、住民に避難場所へ迅速に誘導するための表示灯として図１３に示すようなパトライトがある。このパトライトは、白熱灯光源５０を赤色グローブ５１で覆い、ミラー５２が回転する構成である。別の従来例として図１４に示すような交差点表示灯がある。この交差点表示灯は、光源としてＬＥＤ５３が用いられ、４方向に照射可能なように配置されている。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記従来の避難用表示灯では、パトライトの場合、消費電力が大きく、蓄電設備も過大なものとなる。また、バッテリ駆動時間も設備上あまり長くできず、長い間点灯できないので、安定した避難誘導には不向きであった。また、設備を大型化しても充電には多大なエネルギが必要になり、省資源上の問題がある。さらに、光源の寿命が短く、定期的なメンテナンスが必要であり、非常時での信頼性も低かった。なお、バッテリ充電を太陽電池で行うことを前提とすると、消費電力が大きいことでパネル面積が大きくなり、別途太陽電池の場所が必要になる。
【０００４】
また、交差点表示灯の場合、ＬＥＤは視野角が狭く照射方向が限定されるため、全方向で高い視認性を確保するのが困難であった。
【０００５】
したがって、この発明の目的は、設備を大型化せずに長時間にわたって安定した避難誘導を行うことができ、高い視認性を確保することができる表示灯を提供することである。
【０００６】
【課題を解決するための手段】
上記課題を解決するためにこの発明の請求項１記載の表示灯は、ポールの上部に低消費電力の光源として複数の高輝度ＬＥＤを有する灯具を設け、前記ポールの横の地面上に配置されたバッテリにより前記光源を点灯させる表示灯であって、前記灯具は、前記ポールの上部にポール軸周りに回動可能に被せられ側面に前記光源を照射するための開口部を有する筒状の本体と、前記本体の内部に固定された部品取付台と、前記部品取付台に上下方向に回動自在に取付けられ前記複数の高輝度ＬＥＤを配列した基板とを備え、前記複数の高輝度ＬＥＤを前記基板中央から両側へ移行するにつれて傾斜させることで、前記ポールの軸周りの照射方向の範囲を前記開口部の中心角に相当する角度以上にした。
【０００７】
このように、ポールの上部に高輝度で低消費電力の光源を備えた灯具を設け、光源をバッテリにより点灯させるので、非常時に周辺住民に避難場所を表示し知らせることができる。光源は低消費電力であるので、バッテリによる長時間点灯が可能であり、停電時にも安定した効果をもたらす。また、灯具をポール上部へ取付けることで、より高い位置より表示を行うことにより、広範囲の住民の避難誘導が可能となる。
【０００９】
また、複数の高輝度ＬＥＤを基板に配列するとともに基板中央から両側へ移行するにつれて傾斜させることで、ポールの軸周りの照射方向の範囲を開口部の中心角に相当する角度以上にしたので、広範囲での高い視認性を確保できるとともに、少ない台数で全方向の視認性を確保できる。例えば、照射方向の範囲を９０°以上とすれば、この表示灯を４台使用することにより全方向の視認性を確保できる。
【００１１】
請求項２記載の表示灯は、請求項１において、バッテリは太陽電池により充電される。このように、バッテリは太陽電池により充電されるので、省資源に寄与する。
【００１２】
請求項３記載の表示灯は、請求項１において、太陽電池はポール上部に設置される。このように、太陽電池はポール上部に設置されるので、他の部材に障害になることなく太陽電池の設置スペースを確保できる。
【００１３】
【発明の実施の形態】
この発明の第１の実施の形態の表示灯を図１ないし図５に基づいて説明する。図１はこの発明の第１の実施の形態の表示灯の断面側面図、図２は正面図、図３は断面平面図、図４（ａ）はこの発明の実施の形態の表示灯の全体構成を示す正面図、（ｂ）はＡ−Ａ断面図、図５はこの発明の実施の形態の表示灯の全体構成を示す側面図である。
【００１４】
図４および図５において、１はポール、２はベース板、３は灯具、４は太陽電池、５はバッテリ、６は照明器具、７は飾りである。この表示灯は、ポール１の上部に高輝度で低消費電力の光源を備えた灯具３を設け、光源をバッテリ５により点灯させる。この場合、ポール１は前側に２本、後側に１本の計３本がベース板２に立設されている。前側のポール１ａの上部には照明器具６と飾り７が取付けられ、上端に太陽電池４が設置されている。後側のポール１ｂの上端には灯具３が設けてある。バッテリ５は地面上のポール１の横に配置され、太陽電池４により充電される。
【００１５】
灯具３は、図１〜図３に示すように、後側のポール１ｂの上部に被せられる筒状の本体１０と、本体１０に固定した部品取付台１１と、部品取付台１１に取付けた光源ユニット１２とを備えている。本体１０はポール１ｂの上部に挿入し、ポール１の外周面に突設した支持片１３により支持された状態でボルト１４により固定される。ボルト１４の固定位置とこれに対向する位置において、ポール１ｂと本体１０の隙間にはゴムパッキン１５が配設してある。本体１０の下端には水抜き用切欠き１６が形成してある。また、光源を照射するための開口部１７が設けられ、外側は透明で内側がプリズムのアクリル等からなるパネル１８がねじ１９により取付けてある。開口部１７の中心角は９０°以上で、１２０°が望ましい。
【００１６】
部品取付台１１は、本体１０の天板により垂下した吊持材２０により支持された底板２１およびこれに立設した対向する取付部２２を有する。取付部２２の上部にはボルト挿通穴２２ａが設けられ、光源ユニット１２の基板２３がボルト挿通穴２２ａに挿通されるボルト２４により上下方向に回動自在に取付けられる。光源ユニット１２の光源２５は、複数の高輝度ＬＥＤを互いに照射方向を違わせて設けている。この場合、複数の光輝度ＬＥＤを基板２３に配列するとともに基板２３中央から両側へ移行するにつれて光輝度ＬＥＤを傾斜させることで、ポール１ｂの軸周りの照射方向の範囲を１２０°以上にした。また、基板２３は上記のとおり回動自在に取付けられ、その可動範囲は２０°としている。
【００１７】
次に表示灯の動作について説明する。上記構成の表示灯を避難場所となる防災公園に設置する。災害等による停電時、照明器具６は使用不可となり、太陽電池４により充電されたバッテリ５により夜間、灯具３の光源２５が点灯し避難場所を表示する。この際、光源２５の高輝度ＬＥＤの素子相互に角度を付けたので、視野角を広げ、広範囲の視認性を確保した。また、この表示灯を数台使用し、全方向（３６０°）での視認性を確保できる。すなわち、この表示灯は１台につき１２０°視認可能であるので、４台使用することで実現できる。また、灯具３は水平方向に３６０°回転可能で、基板２３は上下方向可動であるので、設置場所に応じた構成が可能である。
【００１８】
以上のようにこの実施の形態によれば、非常時に周辺住民に避難場所を表示し知らせることができる。光源２５は低消費電力であるので、バッテリ５による長時間点灯が可能であり、停電時にも安定した効果をもたらす。また、灯具３をポール１上部へ取付けることで、より高い位置より表示を行うことにより、広範囲の住民の避難誘導が可能となる。
【００１９】
なお、バッテリ充電は商用電源によってもかまわない。また、表示灯１台当たりの視認性、および使用台数は変えてもよい。
【００２０】
この発明の参考例１を図６に基づいて説明する。図６はこの発明の参考例１の表示灯の斜視図、図７はその光源ユニットの概略図である。図６に示すように、ポール１の上部に灯具３を組み込み、この灯具３を設けたポール１の上端に太陽電池４を設置している。また、図７に示すように、光源ユニット１２の基板２３の形状を円筒形とすることで光源２５を放射状に全周に配置している。基板２３は分割しているが一体の円筒でもよい。また、光源ユニット１２はアクリル等のパネルで覆われている。この参考例では、全方向の高い視認性が得られる。その他の構成効果は、第１の実施の形態と同様である。
【００２１】
また、ポール１の断面形状やデザインに応じて光源ユニットの構成を変えてもよい。すなわち、図８に示すように基板２３を三角形にしてもよく、図９に示すように基板２３を角形にしてもよい。各辺の光源２５は図８では９０°以上の範囲、図９では１２０°以上の範囲でそれぞれ視認できるように向きを変えて配列されている。
【００２２】
図１０はこの発明の参考例２の表示灯の斜視図である。図１０に示すように、ポール１の上端に太陽電池の代わりに風力発電装置３０を設け、これによりバッテリを充電し、灯具３の光源を点灯させる。灯具３は参考例１と同様の構成である。なお、風力発電装置３０は第１の実施の形態にも適用可能である。
【００２３】
図１１はこの発明の参考例３の表示灯の斜視図である。図１１に示すように、ポール１にスピーカ３１を取付けている。これにより、スピーカ３１の音響設備との組み合わせでさらに効果的な避難誘導が可能となる。灯具３は参考例１と同様の構成である。なお、スピーカ３１は第１の実施の形態にも適用可能である。
【００２４】
図１２はこの発明の参考例４の表示灯の要部断面側面図である。図１２に示すように、ポール１の上部に設けた開口部３６付近に灯具３２を設けている。この灯具３２は、開口部３６下側に設け上方に照射する低電力高輝度光源３３（ＨＬＢ：ヘッドライトブロック）と、開口部３６に沿って設けたアクリル等の筒状のパネル３４と、開口部３６の上部に設けた拡散反射板３５とを備えている。拡散反射板３５は表面に凹凸を付け、小型モータで回す構成である。これにより視覚効果が向上し、避難場所への迅速な誘導が可能となる。
【００２５】
【発明の効果】
この発明の請求項１記載の表示灯によれば、ポールの上部に高輝度で低消費電力の光源を備えた灯具を設け、光源をバッテリにより点灯させるので、非常時に周辺住民に避難場所を表示し知らせることができる。光源は低消費電力であるので、バッテリによる長時間点灯が可能であり、停電時にも安定した効果をもたらす。また、灯具をポール上部へ取付けることで、より高い位置より表示を行うことにより、広範囲の住民の避難誘導が可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to an indicator lamp such as an evacuation guidance display lighting fixture.
[0002]
[Prior art]
Conventionally, there is a patrol light as shown in FIG. 13 as an indicator light for promptly guiding residents to an evacuation site at the time of a power failure due to a disaster light. This patrol light is configured such that the incandescent lamp light source 50 is covered with a red globe 51 and the mirror 52 rotates. As another conventional example, there is an intersection indicator as shown in FIG. This intersection indicator lamp uses an LED 53 as a light source, and is arranged so that it can be irradiated in four directions.
[0003]
[Problems to be solved by the invention]
However, in the conventional evacuation indicator lamp, in the case of a patrol light, the power consumption is large and the power storage equipment is excessive. In addition, the battery drive time cannot be made too long due to the equipment and cannot be lit for a long time, so it is not suitable for stable evacuation guidance. Moreover, even if the equipment is enlarged, a large amount of energy is required for charging, which causes a problem in resource saving. Furthermore, the life of the light source was short, regular maintenance was required, and the reliability in an emergency was low. If it is assumed that the battery is charged by a solar cell, the panel area increases due to the large power consumption, and a separate solar cell location is required.
[0004]
Further, in the case of an intersection indicator lamp, since the viewing angle of the LED is narrow and the irradiation direction is limited, it is difficult to ensure high visibility in all directions.
[0005]
Accordingly, an object of the present invention is to provide an indicator lamp that can perform stable evacuation guidance over a long period of time without increasing the size of the facility and can ensure high visibility.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the indicator lamp according to claim 1 of the present invention is provided with a lamp having a plurality of high-intensity LEDs as a light source of low power consumption at the top of the pole, and is disposed on the ground next to the pole. An indicator lamp for turning on the light source by a battery , wherein the lamp has a cylindrical main body having an opening for irradiating the light source on a side surface of the lamp so as to be rotatable around a pole axis. A component mounting base fixed inside the main body, and a substrate on which the plurality of high brightness LEDs are arranged so as to be pivotable in the vertical direction on the component mounting base. By inclining as it moves from the center of the substrate to both sides, the range of the irradiation direction around the axis of the pole is made equal to or greater than the angle corresponding to the central angle of the opening.
[0007]
In this way, a lamp equipped with a light source with high brightness and low power consumption is provided on the top of the pole, and the light source is turned on by the battery. Since the light source has low power consumption, it can be lit for a long time by a battery, and a stable effect can be obtained even during a power failure. In addition, by attaching a lamp to the top of the pole and displaying from a higher position, evacuation guidance for a wide range of residents is possible.
[0009]
In addition, by the hand tilt oblique as the position shifts plurality of high intensity LED to both sides from the center of the substrate as well as arranged in the substrate, and the above angle corresponding to the range of the irradiation direction around the axis of the pole at the center angle of the opening Therefore, high visibility in a wide range can be secured , and visibility in all directions can be secured with a small number of units. For example, if the range of the irradiation direction is 90 ° or more, visibility in all directions can be ensured by using four of these indicator lamps.
[0011]
According to a second aspect of the present invention, in the first aspect , the battery is charged by a solar cell. Thus, since the battery is charged by the solar battery, it contributes to resource saving.
[0012]
According to a third aspect of the present invention, in the first aspect of the present invention, the solar cell is installed on the pole. Thus, since the solar cell is installed on the top of the pole, the installation space for the solar cell can be secured without obstructing other members.
[0013]

Unit 12. The main body 10 is inserted into the upper portion of the pole 1b, and is fixed by bolts 14 while being supported by a support piece 13 protruding from the outer peripheral surface of the pole 1. A rubber packing 15 is disposed in the gap between the pole 1b and the main body 10 at a position where the bolt 14 is fixed and a position facing the bolt 14. A drain notch 16 is formed at the lower end of the main body 10. Further, an opening 17 for irradiating a light source is provided, and a panel 18 made of acrylic or the like having a transparent outer side and a prism on the inner side is attached by a screw 19. The central angle of the opening 17 is 90 ° or more, preferably 120 °.
[0016]
The component mounting base 11 includes a bottom plate 21 supported by a suspension member 20 suspended from the top plate of the main body 10 and an opposing mounting portion 22 erected on the bottom plate 21. A bolt insertion hole 22a is provided in the upper portion of the attachment portion 22, and the substrate 23 of the light source unit 12 is attached so as to be rotatable in the vertical direction by a bolt 24 inserted into the bolt insertion hole 22a.
