Description

本発明は、道路周辺に設置される道路用発光標示体に関するものである。 The present invention relates to a light-emitting sign for a road installed around a road.

道路を通行するドライバーに対して、発光体の発する光によって視線誘導や注意喚起を行うための発光道路標示体については、多くの発明が開示されている。 Many inventions have been disclosed for light-emitting road marking bodies for guiding a gaze and alerting a driver traveling on a road with light emitted from the light-emitting body.

例えば特許文献１には、四面ないし八面の再帰反射器部を有し、その個々の反射器の中心にＬＥＤ発光素子を埋込み設置し、上蓋頭頂部に太陽電池を埋込み設置した警告表示灯が開示されている。 For example, Patent Document 1 discloses a warning indicator lamp having a four- or eight-sided retroreflector section, in which an LED light emitting element is embedded and installed at the center of each reflector, and a solar cell is embedded in an upper lid top.

特許文献１に示す如き警告表示灯は、周囲に等しくＬＥＤ発光素子からの光を放射して多方面より視認可能に形成されているが、設置場所によっては道路などが無く発光標示が不要な方向へも光を放射させ、発光のための電力を無駄に消費するという問題点があった。 The warning indicator lamp as shown in Patent Document 1 is formed so that it can be seen from many directions by emitting light from the LED light emitting element equally around the periphery, but depending on the installation location, there is no road or the like and a light emitting sign is unnecessary. There is also a problem in that light is also emitted to waste power consumed for light emission.

そこで本発明は、発光標示が必要な方向へ光の方向を調整して放射可能な道路用発光標示体を提供するものである。 Accordingly, the present invention provides a light-emitting sign for roads that can emit light by adjusting the direction of light in a direction that requires a light-emitting sign.

上記目的を達成するため、本発明は以下のような構成としている。
すなわち本発明に係る道路用発光標示体は、発光体からの光を外方に放射させる第一の発光部及び第二の発光部が少なくとも設けられ、
前記第一の発光部及び第二の発光部は、光を発光させる発光体と、発光体からの光を集光させるレンズ部とがそれぞれ備えられると共に、
前記レンズ部は上下方向には肉厚を変化させて凸レンズとしての形態を備え、水平方向には肉厚が一定でレンズとしての形態を備えておらず、
前記第一の発光部及び第二の発光部がレンズ部ごとそれぞれ上下を軸方向として回転可能に支持され、
前記第一の発光部及び第二の発光部が放射させる光の水平方向における向きをそれぞれ調整して放射可能となされていることを特徴としている。 In order to achieve the above object, the present invention is configured as follows.
That is, the road light-emitting sign according to the present invention is provided with at least a first light-emitting portion and a second light-emitting portion that radiate light from the light-emitting body outwardly,
The first light emitting unit and the second light emitting unit each include a light emitting body that emits light and a lens unit that collects light from the light emitting body, respectively.
The lens part is provided with a form as a convex lens by changing the thickness in the vertical direction, and is not provided with a form as a lens with a constant thickness in the horizontal direction,
The first light-emitting part and the second light-emitting part are supported so as to be rotatable about the upper and lower axial directions together with the lens part ,
The first light emitting unit and the second light emitting unit can be radiated by adjusting the horizontal direction of light emitted by the first light emitting unit and the second light emitting unit, respectively.

本発明に係る道路用発光標示体によれば、第一の発光部及び第二の発光部がそれぞれ上下を軸方向として回転可能に支持され、第一の発光部及び第二の発光部の放射する光の水平方向の向きを調整して放射可能なので、発光標示を希望する車線や場所へ向けて、各発光部の向きを回転調整させてそれぞれの発する光を放射させることができ、様々な設置場所の状況や表示目的に応じた発光標示を無駄なく行うことができる。一例として、前記第一の発光部と第二の発光部が放射する光が反対方向に放射されるように回転調整させ、道路の進行車線とこの対向車線の両方の通行車両へ向けて発光標示を行うことができる。また他の例として、前記第一の発光部と第二の発光部が放射する光が同一方向に放射されるように回転調整させ、より強調させた発光標示を行うこともできる。また他の例として、本発明の道路用発光標示体を道路のカーブ地点に設置させ、前記第一の発光部と第二の発光部が放射する光をそれぞれカーブ地点へ向かう道路へ向けて回転調整させ、これらの道路を走行する車両へ向けてそれぞれ発光標示を行うこともできる。 According to the light-emitting sign for road according to the present invention, the first light-emitting part and the second light-emitting part are supported so as to be rotatable about the vertical direction, respectively, and the radiation of the first light-emitting part and the second light-emitting part Since the light can be emitted by adjusting the horizontal direction of the light to be emitted, the direction of each light emitting unit can be rotated to adjust the direction of each light emitting part to the desired lane or place, and various light can be emitted. It is possible to perform light emission marking according to the situation of the installation place and the display purpose without waste. As an example, rotation adjustment is performed so that the light emitted from the first light-emitting unit and the second light-emitting unit is emitted in opposite directions, and light emission indications are directed toward both vehicles traveling on the road and on the opposite lane. It can be performed. As another example, it is also possible to perform a light emission indication that is further adjusted by rotating and adjusting so that light emitted from the first light emitting unit and the second light emitting unit is emitted in the same direction. As another example, the road light emitting indicator of the present invention is installed at a curve point of the road, and the light emitted from the first light emitting unit and the second light emitting unit is rotated toward the road toward the curve point, respectively. It is also possible to adjust the light emission indicators to the vehicles traveling on these roads.

また、前記第一の発光部及び第二の発光部にそれぞれ備えた発光体が等しい高さに位置されれば、移動中の車両の運転手や歩行者などの標示対象者が本発明の道路用発光標示体を見たときに、第一の発光部の光が視界から外れた後、第二の発光部の光が視界に入る場合に、それぞれの光が一体的に視認され、発光標示に違和感を感じさせないので、好ましい。 In addition, if the light emitters provided in the first light emitting unit and the second light emitting unit are positioned at the same height, the target person such as a driver or a pedestrian of the moving vehicle can When the light emitted from the first light-emitting unit is out of view and the light from the second light-emitting unit enters the field of view, the respective light is visually recognized as a single unit, This is preferable because it does not make the user feel uncomfortable.

また、上下方向には肉厚を変化させて凸レンズとしての形態を備え、水平方向には肉厚が一定でレンズとしての形態を備えていないレンズ部を前記発光部に備えるので、発光体の発する上下方向の光を前記レンズ部で集光させて外部へ光線を放射させるので、外部へ放射される光がより明るいものとなされ、運転者や歩行者などの標示対象者からの視認性が向上する。また、前記のレンズ部は、水平方向には肉厚が一定でレンズとしての形態を備えていないので、道路用発光標示体から放射される光が水平方向へは広範囲に放射され、標示対象者が移動して道路に設置した道路用発光標示体の脇を通過しようとしたときでも、前記の光を視認可能な領域がより大きく形成され、道路用発光標示体の視認性が向上する。 Further, in the vertical direction by changing the wall thickness comprises the form of a convex lens, in the horizontal direction Runode includes a lens part thickness is not provided with the form as a lens constant to the light emitting portion, light emitter Since the light emitted in the vertical direction is condensed by the lens unit and radiated to the outside, the light radiated to the outside becomes brighter, and visibility from a target person such as a driver or a pedestrian is improved. improves. Further, since the lens portion has a constant thickness in the horizontal direction and does not have a lens shape, the light emitted from the light emitting indicator for road is radiated in a wide range in the horizontal direction, Even when the vehicle moves and tries to pass through the side of the light emitting sign for a road installed on the road, the area where the light can be visually recognized is formed larger, and the visibility of the light emitting sign for a road is improved.

また、本発明に係る道路用発光標示体は、発光体からの光を外方に放射させる第一の発光部及び第二の発光部及び第三の発光部が設けられ、
第一の発光部及び第二の発光部及び第三の発光部はそれぞれ上下を軸方向として回転可能に固定されるとともに、
第一の発光部及び第二の発光部及び第三の発光部はそれぞれ異なる軸で回転可能に固定され、
第一の発光部及び第二の発光部及び第三の発光部が放射させる光の水平方向における向きをそれぞれ調整して放射可能となされていることを特徴としている。 Further, the road illuminating sign according to the present invention is provided with a first light-emitting part, a second light-emitting part and a third light-emitting part that radiate light from the light-emitting body outwardly,
The first light emitting unit, the second light emitting unit, and the third light emitting unit are rotatably fixed with the upper and lower sides as axial directions,
The first light-emitting part, the second light-emitting part, and the third light-emitting part are fixed to be rotatable around different axes,
The first light emitting unit, the second light emitting unit, and the third light emitting unit are configured to be able to emit light by adjusting the direction in the horizontal direction of the light emitted.

また、第一の発光部及び第二の発光部及び第三の発光部がそれぞれ上下を軸方向として回転可能に固定され、第一の発光部及び第二の発光部及び第三の発光部の放射する光の水平方向の向きを調整して放射可能とすれば、３方向へ同時に発光標示を行うことができ、進行車線と対向車線へ向けての発光標示のみならず、三叉路や交差点などに設置してここへ向かう車両へそれぞれ発光標示を行うことができる。また、前記の第一の発光部及び第二の発光部及び第三の発光部をそれぞれ異なる軸で回転可能に固定させれば、第一〜第三の発光部からそれぞれ放射される光が、他の発光部に遮られることなく一方向へ向けて放射可能に回転調整できるので、特定方向にのみ向けて強調させた発光標示を行うことができる。 In addition, the first light emitting unit, the second light emitting unit, and the third light emitting unit are fixed to be rotatable about the vertical direction, respectively, and the first light emitting unit, the second light emitting unit, and the third light emitting unit By adjusting the horizontal direction of the emitted light and making it possible to emit light, it is possible to perform light emission signs in three directions at the same time, not only for light emission signs toward the traveling lane and the opposite lane, but also at three-way intersections and intersections, etc. It is possible to perform light emission markings on vehicles that are installed and heading here. In addition, if the first light emitting unit, the second light emitting unit, and the third light emitting unit are rotatably fixed on different axes, the light emitted from the first to third light emitting units, Since it can be rotated and adjusted so as to be able to radiate in one direction without being blocked by other light emitting units, it is possible to perform a light emission sign that is emphasized only in a specific direction.

In the drawings, reference numeral 1 denotes a road light emitting sign.
The road light emitting indicator 1 of the present embodiment includes two support pillars 6a and 6b formed in a box-like body at the upper part and the lower part, respectively, and three support pillars 2 spanned between these support parts 6a and 6b. The upper end and the lower end are respectively supported and fixed.
The three struts 2 are arranged side by side in a position corresponding to the front of the light emitting indicator 1 for the road 1 and two in the position behind the three, and the arrangement in the horizontal section forms three corners of the triangle. It is provided as follows.
The light-emitting sign body 1 for road supplies and stores the electric power generated by a separately formed solar cell (not shown) to the power storage unit 62 built in the support column support 6a. The electric power stored in the power storage unit 62 is supplied to the light emitting body 41 of the light emitting unit 4 attached to the support column 2 through the control unit 63 similarly installed in the support column support 6a, and causes it to emit light. The light emitters 41 of the light emitters 4 attached to the respective struts 2 are controlled to be turned on and off by the controller 63, and each light emitter 41 is turned on and off individually or simultaneously to emit light in various light emission patterns. It is possible. The light-emitting sign body 1 for roads is attached to a fixing pole (not shown) formed separately, and the height from the light-emitting parts 4 is adjusted to the height of the eyes of a main sign target person such as a pedestrian or a vehicle driver. It is fixed so that light is emitted, and is installed at the side of a road or at an intersection.

２は支柱である。支柱２はアルミニウム合金を押出成形によって成形されており、円柱状の側壁２２の前方に長手方向に切り欠くように形成された開口部２１を備えた略Ｃ字状の断面形状に形成している。
側壁２２の内側には開口部２２の各々の端縁に沿うように凹溝２３が形成されており、この両凹溝２３はそれぞれに開口方向を向けて対向するように設けられている。 2 is a support | pillar. The support column 2 is formed by extrusion molding of an aluminum alloy, and is formed in a substantially C-shaped cross-sectional shape having an opening 21 formed so as to be cut out in a longitudinal direction in front of a cylindrical side wall 22. .
A concave groove 23 is formed inside the side wall 22 along each edge of the opening 22, and both the concave grooves 23 are provided so as to face each other in the opening direction.

４は発光部である。本実施形態では、発光部４は、後面が開口した箱体の透光性の保護カバー部４２を前面に有し、保護カバー部４２の開口部分にはこれを塞ぐように背面板４７が取り付けられ、発光部４が箱形のユニット体に形成されている。
保護カバー部４２の両側の側面には、保護カバー部４２の上面から下面に亘るように突条部４８が形成されており、この突条部４８は保護カバー部４２の両側の側面において互いが反対方向を向くように形成されている。
また、保護カバー部４２の上面および下面はそれぞれ平面に形成されている。
保護カバー部４２の材質としては、透明なポリカーボネート樹脂を用いることができ、これに限らず透光性を有するものであれば何でも良く、アクリル樹脂やガラスなどを用いてもよい。本実施形態ではポリカーボネート樹脂を用いている。 Reference numeral 4 denotes a light emitting unit. In the present embodiment, the light emitting unit 4 has a box-shaped translucent protective cover portion 42 with an open rear surface on the front surface, and a back plate 47 is attached to the opening portion of the protective cover portion 42 so as to close it. The light emitting section 4 is formed in a box-shaped unit body.
On the side surfaces on both sides of the protective cover portion 42, ridge portions 48 are formed so as to extend from the upper surface to the lower surface of the protective cover portion 42. It is formed to face the opposite direction.
Moreover, the upper surface and lower surface of the protective cover part 42 are each formed in a plane.
As a material of the protective cover portion 42, a transparent polycarbonate resin can be used, and is not limited thereto, and any material having translucency may be used, and an acrylic resin, glass, or the like may be used. In this embodiment, a polycarbonate resin is used.

保護カバー部４２と背面板４７とに囲われた発光部４の内部には、発光体４１が内装されている。本実施形態では発光体４１にＬＥＤを用いており、発光体４１は発光させる光の向きを同じ方向に向けて配線基板４９上に横方向に３個一列に取り付けられ、これを上下方向に二列配置して合計６個ずつ取り付けられている。配線基板４９は、発光体４１から発する光が保護カバー部４２の前面に向けられるように、発光部４に内装されている。このとき、発光体４１の列の向きが、発光部４の上下方向に沿うように配置されており、発光部４の側壁に形成された突条部４８と同一方向としている。 Inside the light emitting part 4 surrounded by the protective cover part 42 and the back plate 47, a light emitting body 41 is housed. In the present embodiment, LEDs are used as the light emitters 41. The light emitters 41 are mounted on the wiring board 49 in a row in the same direction with the direction of light to be emitted in the same direction. A total of 6 pieces are attached in a row. The wiring board 49 is housed in the light emitting unit 4 so that light emitted from the light emitting body 41 is directed to the front surface of the protective cover unit 42. At this time, the direction of the row of the light emitters 41 is arranged along the vertical direction of the light emitting unit 4, and is in the same direction as the protrusion 48 formed on the side wall of the light emitting unit 4.

突条部４８の大きさと間隔は、支柱２に形成された凹溝２３の大きさと対向する各凹溝２３同士の間隔にそれぞれ対応するように形成されており、発光部４はその前面を支柱２の前方に向けて、前記凹溝２３に突条部４８を挿入して支柱２に固定されている。発光部４は、突条部４８を凹溝２３に挿入して固定されるので、発光部４は両側の側面で強固に固定され、方向などのずれを容易に起こさない。本実施形態では、支柱に設けた開口部２１と凹溝２３の長さを発光部４を複数段積みして設置できる大きさに形成しているので、凹溝２３に突条部４８を挿入するだけで各発光部４を容易に段積み可能としている。また、発光部４の発光体４１は突条部４８の方向に合わせて列状に配置しているので、複数の発光部４を同一の凹溝２３に段積みしたとき、各発光部４の発光体４１が自動的に同じ方向に沿った列として配置される。 The size and interval of the ridges 48 are formed so as to correspond to the size of the recesses 23 formed opposite to the size of the recesses 23 formed in the support column 2, respectively. The protrusions 48 are inserted into the concave grooves 23 toward the front of 2 and fixed to the support column 2. Since the light emitting portion 4 is fixed by inserting the protrusion 48 into the concave groove 23, the light emitting portion 4 is firmly fixed on the side surfaces on both sides and does not easily shift in direction or the like. In this embodiment, the length of the opening 21 and the groove 23 provided in the support column is formed to be large enough to be installed by stacking a plurality of light emitting sections 4, so that the protrusion 48 is inserted into the groove 23. Thus, the light emitting units 4 can be easily stacked. Further, since the light emitters 41 of the light emitting units 4 are arranged in a row in accordance with the direction of the protrusions 48, when a plurality of light emitting units 4 are stacked in the same concave groove 23, The light emitters 41 are automatically arranged as rows along the same direction.

本実施形態では、突条部４８に対応した凹溝２３に係合させて発光部４を段積み可能とできるので、突条部４８に対応した凹溝２３の長さを変更することで段積みする発光部４の個数を容易に変更できる。例えば支柱２の長さを変更して、それに応じた個数の発光部４を取り付けることが可能である。 In the present embodiment, the light emitting unit 4 can be stacked by engaging with the concave groove 23 corresponding to the ridge portion 48, so that the step can be performed by changing the length of the concave groove 23 corresponding to the ridge portion 48. The number of light emitting units 4 to be stacked can be easily changed. For example, it is possible to change the length of the column 2 and attach the number of light emitting units 4 corresponding to the length.

５は反射体である。
発光部４は１本の支柱２にそれぞれ６個ずつ取り付けられており、支柱２の上方と下方にそれぞれ３個づつ取り付けられ、これらの間に反射体５が取り付けられている。
反射体５は前面がアールを描いて前方に突出するかまぼこ形状の箱体に形成され、前面が光の再帰反射性を有するように構成されている。反射体５の左右の側面には、発光部４の突条部４８と同じ大きさと間隔の突条部５２がその上面から下面に至るように上下方向にそれぞれ形成されており、発光部４と同様に前記の突条部５２を支柱２の凹溝２３に挿入させて、支柱２に固定される。
反射体５を発光部４と上下方向に並設させて設けることで、発光部４の発する光と、反射体５によって再帰反射される光とが、それぞれ光の強さや色調を異ならせて視認されるので、視認される光が複雑でより誘目性を高めたものとなされ、道路用発光標示体１の視認性を高める。 Reference numeral 5 denotes a reflector.
Six light emitting units 4 are attached to each of the columns 2, and three light emitting units 4 are mounted above and below the columns 2, respectively, and reflectors 5 are mounted therebetween.
The reflector 5 is formed in a semi-cylindrical box shape with the front surface drawing a round shape and protruding forward, and the front surface is configured to have retroreflectivity of light. On the left and right side surfaces of the reflector 5, protrusions 52 having the same size and spacing as the protrusions 48 of the light emitting part 4 are formed in the vertical direction so as to reach from the upper surface to the lower surface. Similarly, the protrusion 52 is inserted into the groove 23 of the support 2 and fixed to the support 2.
By providing the reflector 5 in parallel with the light emitting unit 4 in the vertical direction, the light emitted from the light emitting unit 4 and the light retroreflected by the reflector 5 are visually recognized with different intensity and color tone. Therefore, the visually recognized light is complicated and more attractive, and the visibility of the road luminescent sign 1 is enhanced.

Each is abutted and prevented from being pulled out, and the column 2 is fixed so as to be sandwiched between the column supports 6a and 6b.
The column 2 is configured such that the cylindrical rotation support portion 33 is rotated in the circular cap insertion hole 61 so that the direction of the column 2 can be adjusted with respect to the column supports 6a and 6b.

支柱支持体６ａ、６ｂの側壁には、内側に雌ねじが形成された固定ねじ穴６５が形成され、ここに固定ねじ７が螺入されている。雄ねじ部分を支柱支持体６ａ、６ｂの内側に螺入させた固定ねじ７は、より深く螺入されることで、その先端を回転キャップ３の回転固定部３３の外周面に当接させ、これを押圧可能に形成されている。回転キャップ３は、回転固定部３３の外周面を固定ねじ７の先端で押圧されることで、キャップ挿入穴６１の開口縁に回転固定部３３が押し付けられてその回転が抑止され、支柱支持体６ａ、６ｂに架設された支柱２の回転が防止される。
本実施形態の道路用発光標示体１は、支柱支持体６ａ、６ｂに回転可能に支持された支柱２が意図しない状況で回転しないように、上記のような回転防止の機能を設けているが、これに限るものではなく、固定ねじ７などを設けずに常時回転可能に形成させてもよい。 On the side walls of the column supports 6a and 6b, there are formed fixing screw holes 65 having internal threads formed therein, and the fixing screws 7 are screwed therein. The fixing screw 7 in which the male screw portion is screwed into the inside of the support pillars 6a and 6b is deeply screwed to bring its tip into contact with the outer peripheral surface of the rotation fixing portion 33 of the rotation cap 3, Is formed so that it can be pressed. The rotation cap 3 is pressed against the opening edge of the cap insertion hole 61 by pressing the outer peripheral surface of the rotation fixing portion 33 with the tip of the fixing screw 7, and the rotation is suppressed, and the column support is supported. Rotation of the column 2 erected on 6a and 6b is prevented.
The road luminous indicator 1 of the present embodiment is provided with the above-described anti-rotation function so that the column 2 rotatably supported by the column supports 6a and 6b does not rotate in an unintended situation. However, the present invention is not limited to this, and it may be formed so as to be always rotatable without providing the fixing screw 7 or the like.

また、支柱支持体６ａ、６ｂに設けられたキャップ挿入穴６１は、その開口縁が各支柱支持体６の内側へ突出するように突出部６２が形成されている。突出部６２が設けられることで、キャップ挿入穴６１の端縁部分の強度が向上し、より強固に各支柱２を支持するとともに、各支柱２の回転による摩耗を抑制させている。また、前記の固定ねじ７による回転キャップ３の回転の抑止においても、突出部６２によるキャップ挿入穴６１の強度向上により、キャップ挿入穴６１の開口縁に回転固定部３１をより強く押し付けることができ、より確実に各支柱２の回転が防止できる。 Further, the cap insertion hole 61 provided in the support pillars 6 a and 6 b is formed with a protrusion 62 so that the opening edge protrudes inward of each support pillar 6. By providing the protruding portion 62, the strength of the edge portion of the cap insertion hole 61 is improved, and the struts 2 are supported more firmly, and wear due to rotation of the struts 2 is suppressed. Further, also in the suppression of the rotation of the rotating cap 3 by the fixing screw 7, the rotation fixing portion 31 can be pressed more strongly against the opening edge of the cap insertion hole 61 by improving the strength of the cap insertion hole 61 by the protruding portion 62. Thus, the rotation of each support column 2 can be prevented more reliably.

回転キャップ３の板部３１には、回転固定部３３を設けた面から他方の面に至る貫通穴３４が設けられている。これは、支柱支持体６ａに内装された蓄電部６２から支柱２に取り付けられた発光部４の発光体４１へ電力を供給する電線を挿通可能にするためのものである。 The plate portion 31 of the rotation cap 3 is provided with a through hole 34 from the surface on which the rotation fixing portion 33 is provided to the other surface. This is to enable insertion of an electric wire that supplies electric power from the power storage unit 62 built in the support column support 6 a to the light emitter 41 of the light emitting unit 4 attached to the support column 2.

回転キャップ３を介して回転可能に支持された支柱２は、開口部２１の後方の側壁２２が半円形に形成されており、支柱２の回転を行う際に、側壁２２の外側面が他の部材に当接することがなく、回転の障害とならないように形成されている。 The support column 2 that is rotatably supported via the rotation cap 3 has a side wall 22 at the back of the opening 21 formed in a semicircular shape. It is formed so as not to interfere with rotation without contacting the member.

３本の支柱２に取り付けられた各発光部４は、道路用発光標示体１の前方にあたる位置の支柱２ｃに取り付けられた発光部４が第三の発光部４ｃを構成し、その後方右側の位置に並設された支柱２ａに取り付けられた発光部４が第一の発光部４ａを構成し、後方左側の位置に並設された支柱２ｂに取り付けられた発光部４が第二の発光部４ｂをそれぞれ構成する。
前記第一〜第三の発光部４ａ、４ｂ、４ｃは、支柱支持体６ａ、６ｂに架設された各支柱２ａ、２ｂ、２ｃの回転によって、それぞれが放射する光の水平方向における向きを調整可能に構成されている。
各支柱２ａ〜２ｃに取り付けられた各発光部４ａ〜４ｃは、水平方向において、保護カバー部４２の向けられた方向へのみ光を放射させ、前記の方向以外へは光を放射しないように構成されている。 Each of the light emitting units 4 attached to the three support columns 2 is composed of the light emitting unit 4 attached to the support column 2c at a position in front of the road light emitting indicator 1 to form a third light emitting unit 4c. The light-emitting part 4 attached to the column 2a arranged in parallel at the position constitutes the first light-emitting part 4a, and the light-emitting part 4 attached to the column 2b arranged in parallel at the rear left position is the second light-emitting part. 4b is configured.
The first to third light emitting units 4a, 4b, 4c can adjust the horizontal direction of the light emitted by the rotation of the columns 2a, 2b, 2c installed on the column supports 6a, 6b. It is configured.
Each light-emitting part 4a-4c attached to each support | pillar 2a-2c is comprised so that light may be radiated only to the direction to which the protective cover part 42 was directed in the horizontal direction, and light is not radiated | emitted except the said direction. Has been.

図６は各発光部４から放射させる光の向きを調整させた状況を示す図１のＡ−Ａ断面図である。
支柱支持体６ａ、６ｂに回転可能に固定された各支柱２ａ、２ｂ、２ｃは、本実施形態において、それぞれ左右の周方向へ９０゜ずつ、合計１８０゜の回転が可能に固定されている。
上記のように各支柱２ａ、２ｂ、２ｃを構成することで、これらを回転調整させて、図２（イ）に示すように第一〜第三の各発光部４ａ、４ｂ、４ｃの光をそれぞれ９０゜間隔で異なる方向へむけて放射させることができ、交差点や三叉路において、各道路の方向へ向けて発光標示させることが可能である。
また、図６（イ）に示すように、第一〜第三の発光部４ａ、４ｂ、４ｃの光をそれぞれ４５゜間隔で前方へむけて放射させることができ、前方へ発光を集中させて強調させた発光標示を行うことも可能である。
また、図６（ロ）に示すように、第一及び第二の発光部４ａ、４ｂをそれぞれ後方へ向け、第三の発光部４ｃをこれと反対の前方に向けて、後方への発光標示をより強調させて１８０゜逆の方向へそれぞれ発光標示を行うこともできる。 6 is a cross-sectional view taken along the line AA of FIG. 1 showing a state in which the direction of light emitted from each light emitting unit 4 is adjusted.
In this embodiment, the columns 2a, 2b, and 2c that are rotatably fixed to the column supports 6a and 6b are fixed so that they can rotate by 90 ° in the left and right circumferential directions, respectively, for a total of 180 °.
By configuring each column 2a, 2b, and 2c as described above, these are rotated and adjusted, and the lights of the first to third light emitting units 4a, 4b, and 4c are emitted as shown in FIG. The light can be emitted toward different directions at intervals of 90 °, and the light emission can be indicated toward the direction of each road at an intersection or a three-way road.
In addition, as shown in FIG. 6 (a), the light of the first to third light emitting portions 4a, 4b, and 4c can be emitted toward the front at 45 ° intervals, and the light emission is concentrated forward. It is also possible to perform an emphasized luminescent sign.
Further, as shown in FIG. 6 (b), the first and second light emitting portions 4a and 4b are directed rearward and the third light emitting portion 4c is directed forward opposite to the first and second light emitting portions 4a and 4b. It is also possible to perform the luminescence indication in the opposite direction by 180 ° with more emphasis.

本実施形態の道路用発光標示体１は、３本の支柱２ａ〜２ｃを備え、これにそれぞれ第一〜第三の発光部４ａ、４ｂ、４ｃを取り付けられているが、これに限るものではなく、２本の支柱２ａ、２ｂのみを備えてこれにそれぞれ第一〜第二の発光部４ａ、４ｂを設けても良いし、４本以上の支柱２にそれぞれ発光部４を設けても良い。
図７は本発明に係る道路用発光標示体の実施の他の一形態を示す断面図である。
本実施形態の道路用発光標示体は、図１の実施形態より支柱２ｃと発光部４ｃを省き、２本の支柱２ａ、２ｂを並設させて、第一の発光部４ａを支柱２ａに、第二の発光部４ｂを支柱２ｂにそれぞれ設けている。また本実施形態においては、各支柱２ａ、２ｂの回転の角度を、それぞれ９０゜の範囲で回転可能に形成させている。このように各支柱２ａ、２ｂを形成させることで、第一の発光部４ａと第二の発光部４ｂとの光の放射する向きのなす角を０〜１８０゜の範囲で調整可能に構成でき、すなわち図７（イ）に示すように第一及び第二の発光部４ａ、４ｂの光の方向をそれぞれ同一方向へ放射させることも、図７（ロ）に示すように反対方向へ放射させることもできる。 The road light emitting indicator 1 of the present embodiment includes three support columns 2a to 2c, and the first to third light emitting portions 4a, 4b, and 4c are attached thereto, respectively. However, the present invention is not limited to this. Alternatively, only two support columns 2a and 2b may be provided, and the first to second light emitting units 4a and 4b may be provided on the two support columns 2a and 2b, respectively, or the light emitting units 4 may be provided on four or more support columns 2, respectively. .
FIG. 7 is a cross-sectional view showing another embodiment of the road luminous indicator according to the present invention.
The road luminous indicator of the present embodiment omits the support column 2c and the light emitting unit 4c from the embodiment of FIG. 1 and has two columns 2a and 2b arranged side by side, and the first light emitting unit 4a on the column 2a. The 2nd light emission part 4b is provided in the support | pillar 2b, respectively. In the present embodiment, the rotation angles of the columns 2a and 2b are formed so as to be rotatable within a range of 90 °. Thus, by forming each support | pillar 2a, 2b, it can comprise so that the angle which the direction which the light emission of the 1st light emission part 4a and the 2nd light emission part 4b radiates | emits can be adjusted in the range of 0-180 degree. That is, as shown in FIG. 7 (a), the light directions of the first and second light emitting sections 4a and 4b are radiated in the same direction, as shown in FIG. 7 (b). You can also.

また、図８は本発明に係る道路用発光標示体の実施の他の一形態を示す断面図であり、図７に示す道路用発光標示体の各支柱２ａ、２ｂの回転の角度を、それぞれ１８０゜の範囲で回転可能に形成させている点が、図７の実施形態と異なる。
各支柱２ａ、２ｂを上記のように形成することで、道路用発光標示体１に設置方向に係わらず任意の方向へ各発光部４からの光を放射させることができ、図８（イ）に示すように道路用発光標示体１の前方のみならず後方へ向けて、第一および第二の発光部４ａ、４ｂの光を放射させることができ、また図８（ロ）に示すように、第一及び第二の発光部４ａ、４ｂのそれぞれの光の方向を反対方向に向けて道路用発光標示体の斜め方向へ自由に放射させることができる。 FIG. 8 is a cross-sectional view showing another embodiment of the road illuminating sign according to the present invention. The rotation angle of each column 2a, 2b of the road luminescent sign shown in FIG. 7 is different from the embodiment of FIG. 7 in that it is formed to be rotatable within a range of 180 °.
By forming each column 2a, 2b as described above, the light emitting indicator 4 for road 1 can emit light from each light emitting portion 4 in any direction regardless of the installation direction. As shown in FIG. 8, the light emitted from the first and second light emitting portions 4a and 4b can be emitted not only in front of but also in the rear of the road light emitting indicator 1, and as shown in FIG. The first and second light-emitting portions 4a and 4b can be freely radiated in the oblique direction of the light-emitting sign for the road with the light directions directed in opposite directions.

前記のように各支柱２と各発光部４とを構成させることで、発光部４から放射させる光の向きを調整させて、発光標示を行う方向を、道路の一方向へ集中させて行うことも、直線状の道路に置いて通行車線と対向車線に同時に行うことも、カーブに向かうそれぞれの道路に向けて同時に行うこともでき、不要な方向への発光標示を行うことなく、設置場所の状況や目的に応じた発光標示を行うことができるため、道路用発光標示体１に備えた各発光部４の回転角度は９０゜以上の範囲で調整可能に形成するのが好ましく、１８０゜以上の範囲で調整可能に形成するのがより好ましい。 By configuring each support column 2 and each light emitting unit 4 as described above, the direction of the light emitted from the light emitting unit 4 is adjusted, and the direction in which the light emission indication is performed is concentrated in one direction of the road. However, it can be placed on a straight road in the traffic lane and the oncoming lane at the same time, or simultaneously on each road going to the curve. Since it is possible to perform a light emission sign according to the situation and purpose, it is preferable that the rotation angle of each light emitting unit 4 provided in the light emission indicator for road 1 is formed to be adjustable within a range of 90 ° or more, and 180 ° or more. It is more preferable to form it in an adjustable range.

また前記の実施形態において、異なる支柱２に取り付けられた発光部４は、それぞれの発光部４の備えた発光体の上下の位置が等しい高さにそれぞれ位置するように固定されている。
異なる支柱の各発光部４の発光体がそれぞれ等しい高さに位置するように設けられることで、各発光部４からそれぞれ放射される光が、一体的に視認されるようになされる。
例えば、図７（イ）に示すように、第一および第二の発光部４ａ、４ｂがともに道路用発光標示体１の前方に向けて光を放射させるように各支柱２ａ、２ｂを回転調整させた場合において、第一の発光部４ａと第二の発光部４ｂとにそれぞれ備えられた発光体が同じ高さに位置しているので、これを視認する標示対象者が発光標示に対する違和感を感じない。
また、図６（イ）に示すように、第一〜第三の発光部４ａ、４ｂ、４ｃが前方と斜め前方へ向けてそれぞれ光を放射させるように各支柱２ａ〜２ｃを回転調整させた場合において、これを視認する標示対象者が前方から道路用発光標示体の脇を通過してこの発光標示を見たときに、第三の発光部４ｃの光の視認可能領域から外れて第一の発光部４ａ又は第二の発光部４ｂの光の視認可能領域に入っても、それぞれの発光部４の発光体の高さがずれないので、これを視認する標示対象者が発光標示に対する違和感を感じない。
上記のように各発光部４から放射される光が標示対象者から違和感無く視認されるので、異なる発光部４の発光体の上下の位置はそれぞれ等しい高さに固定させるのが好ましい。
また、各発光部４がそれぞれ異なる支柱２に固定されて個別に回転可能に設けられれば、上記のように発光体の上下の位置をそれぞれ等しい高さに固定させた各発光部４を道路用発光標示体１に容易に設けることができる。
また、図１に示す実施形態のように、各発光部４ａ〜４ｃがそれぞれ異なる軸で回転する支柱２ａ〜２ｃに個別に設けられることで、各支柱２ａ〜２ｃの向きを調整させて、各発光部４ａ〜４ｃからの光をそれぞれ異なる方向へ向けて放射することができるとともに、各発光部４ａ〜４ｃを一方向へ集中的に放射させるように向きを調整させることもできる。 Moreover, in the said embodiment, the light emission part 4 attached to the different support | pillar 2 is being fixed so that the up-and-down position of the light-emitting body with which each light emission part 4 was each located in the same height.
By providing the light emitters of the light emitting units 4 of the different columns so as to be positioned at the same height, the light emitted from the light emitting units 4 can be visually recognized integrally.
For example, as shown in FIG. 7 (a), each column 2a, 2b is rotationally adjusted so that both the first and second light emitting portions 4a, 4b emit light toward the front of the road light emitting indicator 1. In this case, since the light emitters respectively provided in the first light emitting unit 4a and the second light emitting unit 4b are located at the same height, the target person visually recognizing this feels uncomfortable with the light emitting sign. do not feel.
Further, as shown in FIG. 6 (a), the support pillars 2a to 2c are rotationally adjusted so that the first to third light emitting units 4a, 4b, and 4c emit light forward and obliquely forward, respectively. In this case, when a signing person who visually recognizes the light passes through the side of the road light emitting sign from the front and sees the light emitting sign, the first object is removed from the light visible region of the third light emitting unit 4c. Even if the light emitting part 4a or the second light emitting part 4b enters the region where the light can be visually recognized, the height of the light emitters of the respective light emitting parts 4 does not deviate. I don't feel.
As described above, since the light emitted from each light emitting unit 4 is visually recognized by the person to be labeled without a sense of incongruity, the upper and lower positions of the light emitters of different light emitting units 4 are preferably fixed at the same height.
Further, if each light emitting unit 4 is fixed to a different support column 2 and can be individually rotated, each light emitting unit 4 in which the upper and lower positions of the light emitter are fixed at the same height as described above is used for roads. It can be easily provided on the luminescent indicator 1.
Further, as in the embodiment shown in FIG. 1, the light emitting units 4 a to 4 c are individually provided on the support columns 2 a to 2 c that rotate on different axes, respectively, so that the orientation of each support column 2 a to 2 c is adjusted, Light from the light emitting units 4a to 4c can be emitted in different directions, and the direction can be adjusted so that each of the light emitting units 4a to 4c is radiated intensively in one direction.

前記の実施形態に示す道路用発光標示体１では、発光部４の保護カバー部４２の前面は平面に形成されており、保護カバー部４２の前面には発光体４１の位置に対応する部分にレンズ部４３が設けられている。レンズ部４３は発光体４１から発せられる光を透過して発光部４の外部に出射する際に、光を集光するように形成されている。 In the road light emitting indicator 1 shown in the above embodiment, the front surface of the protective cover portion 42 of the light emitting portion 4 is formed flat, and the front surface of the protective cover portion 42 has a portion corresponding to the position of the light emitting body 41. A lens unit 43 is provided. The lens portion 43 is formed so as to collect light when transmitting the light emitted from the light emitting body 41 and emitting it to the outside of the light emitting portion 4.

レンズ部４３は、正面視からの形状が、横長の長方形の左右両辺をそれぞれ横方向に至るほどアールを描いて中央に集束する半円形とした形状に形成させている。
図９は図４の発光部４のレンズ部４３の断面を示す図であり、（イ）はＡ−Ａ断面図であり、（ロ）はＢ−Ｂ断面図である。
本実施形態において、保護カバー部４２に設けられたレンズ部４３は、保護カバー部４２の前面より前方に突出して形成される前方レンズ部４６Ａと、同様に保護カバー部４２の背面に形成される後方レンズ部４６Ｂとを備えている。 The lens portion 43 is formed in a semicircular shape in which the shape when viewed from the front is drawn in a round shape and converges to the center as the horizontal direction of the left and right sides of the horizontally long rectangle is increased.
FIG. 9 is a view showing a cross section of the lens portion 43 of the light emitting section 4 in FIG. 4, (A) is an AA cross section, and (B) is a BB cross section.
In the present embodiment, the lens portion 43 provided in the protective cover portion 42 is formed on the back surface of the protective cover portion 42 in the same manner as the front lens portion 46 </ b> A formed to protrude forward from the front surface of the protective cover portion 42. And a rear lens portion 46B.

図９（イ）に示すように、レンズ部４３の上下の断面において、前方レンズ部４６Ａは保護カバー部４２の前面より前方に突出する円弧状の断面を有するように形成されており、前方レンズ部４６Ａの前面の円弧状の形状が前部レンズ面４３ａとして機能する。
また後方レンズ部４６Ｂは、前方レンズ部４６Ａに対応する位置において、保護カバー部４２の背面が前方に向けてくぼむように形成され、このくぼみの形状が後部レンズ面４３ｂとして機能する。このとき、後部レンズ面４３ｂは前部レンズ面４３ａより小さな曲率を有する円弧形状に形成されている。前部レンズ面４３ａと後部レンズ面４３ｂとを上記のように形成させることで、レンズ部４３の上下断面形状は、レンズ面の中央が最も肉厚で、端部に至るほど肉薄となり、レンズ部４３が凸レンズとして機能するようになされている。 As shown in FIG. 9A, in the upper and lower cross sections of the lens portion 43, the front lens portion 46A is formed to have an arc-shaped cross section that protrudes forward from the front surface of the protective cover portion 42. The arcuate shape of the front surface of the portion 46A functions as the front lens surface 43a.
The rear lens portion 46B is formed such that the back surface of the protective cover portion 42 is recessed forward at a position corresponding to the front lens portion 46A, and the shape of this recess functions as the rear lens surface 43b. At this time, the rear lens surface 43b is formed in an arc shape having a smaller curvature than the front lens surface 43a. By forming the front lens surface 43a and the rear lens surface 43b as described above, the vertical cross-sectional shape of the lens portion 43 is the thickest at the center of the lens surface, and becomes thinner toward the end portion. 43 functions as a convex lens.

図１０は図９のレンズ部４３から上下方向に放射される光線の状況を示す図である。
図１０（イ）に示すように、発光体４１より放射状の光Ｎを発光させたときに、レンズ部４３を介さない場合には、光Ｎはそのまま光Ｎ１〜Ｎ２の範囲へ直進して放射されるが、レンズ部４３の上下の断面を上記のように形成させることで、後部レンズ面４３ｂと前部レンズ面４３ａとの曲率の大きさの差異によってレンズ部４３が凸レンズとして機能するようになされて発光体４１からの光Ｎが集光され、上下方向への放射範囲を狭められた光線Ｔ１〜Ｔ２として前部レンズ面４３ａから放射される。
光線Ｔ１〜Ｔ２は、レンズ部４３によって集光されることで、光Ｎよりも明るい光として視認されるので、道路用発光標示体１の視認性を向上させる。 FIG. 10 is a diagram showing the state of light rays emitted from the lens unit 43 in FIG. 9 in the vertical direction.
As shown in FIG. 10 (a), when the radial light N is emitted from the light emitter 41, the light N goes straight to the range of the light N1 to N2 and radiates without passing through the lens unit 43. However, by forming the upper and lower cross-sections of the lens portion 43 as described above, the lens portion 43 functions as a convex lens due to the difference in curvature between the rear lens surface 43b and the front lens surface 43a. The light N from the illuminant 41 is collected and emitted from the front lens surface 43a as light rays T1 to T2 whose emission range in the vertical direction is narrowed.
Since the light rays T1 to T2 are condensed by the lens unit 43 and are visually recognized as light brighter than the light N, the visibility of the road luminescent sign 1 is improved.

図９（ロ）に示すように、レンズ部４３の水平断面において、保護カバー部４２の前面より前方に突出する前方レンズ部４６Ａの表面に形成されている前部レンズ面４３ａは、その形状が水平方向へ向けて直線形状に形成されており、その両端では端に至るほど前方への突出大きさが小さくなるように円弧を描いて保護カバー部４２の側壁外面に至るように形成されている。
また、前記前方レンズ部４６Ａに対応する位置において、保護カバー部４２の背面が前方へ向けてくぼむように形成された後部レンズ面４３ｂは、前部レンズ面４３ａと同様に、その形状が水平方向に向けて直線形状に形成され、その両端において端に至るほど前方へくぼむ大きさが小さくなるように円弧を描いて保護カバー部４２の側壁内面に至るように形成されている。
前部レンズ面４３ａと後部レンズ面４３ｂとの水平方向の形状を直線形状とすることで、レンズ部４３の水平方向にレンズ厚さが均一な部分が形成され、これが後述する非集光部４３ｃとして機能する。
また、後部レンズ面４３ｂの両端部分の円弧の曲率の大きさは、前部レンズ面４３ａの両端部分の円弧よりも小さく形成されている。 As shown in FIG. 9B, the front lens surface 43a formed on the surface of the front lens portion 46A protruding forward from the front surface of the protective cover portion 42 in the horizontal cross section of the lens portion 43 has a shape. It is formed in a straight line shape in the horizontal direction, and is formed so as to reach the outer surface of the side wall of the protective cover portion 42 by drawing an arc so that the protruding size at the both ends is smaller toward the end. .
Further, the rear lens surface 43b formed so that the back surface of the protective cover portion 42 is recessed forward at a position corresponding to the front lens portion 46A has a horizontal shape similar to the front lens surface 43a. It is formed so as to reach the inner surface of the side wall of the protective cover portion 42 by drawing a circular arc so that the size of the recess is reduced toward the ends at both ends.
By making the horizontal shape of the front lens surface 43a and the rear lens surface 43b linear, a portion having a uniform lens thickness is formed in the horizontal direction of the lens portion 43, which is a non-light-collecting portion 43c described later. Function as.
Moreover, the magnitude | size of the curvature of the circular arc of the both ends of the rear lens surface 43b is formed smaller than the circular arc of the both ends of the front lens surface 43a.

レンズ部４３の水平断面を上記のように形成させることで、レンズ部４３の後方に配置した発光体４１より発した光が後部レンズ面４３ｂの両端の円弧部分に入光した場合は、図９（イ）に示す側面視におけるレンズ部４３と同様の集光効果を奏し、水平方向への放射範囲を狭められた光線として前部レンズ面４３ａより放射される。 When the horizontal section of the lens unit 43 is formed as described above, the light emitted from the light emitter 41 disposed behind the lens unit 43 enters the arc portions at both ends of the rear lens surface 43b. The light condensing effect similar to that of the lens unit 43 in the side view shown in (a) is obtained, and the light is emitted from the front lens surface 43a as a light beam whose radiation range in the horizontal direction is narrowed.

しかし、発光体４１からの光Ｎが前記の非集光部４３ｃに入光した場合、図１０（ロ）に示すように、レンズ部４３の厚みが均一に形成されているためレンズとして機能せず、入光した光が集光されることがなく、前部レンズ面４３ａから放射される光線Ｔ１〜Ｔ２は水平方向への放射範囲が狭められずに、レンズ部４３を介さずに放射される光Ｎ１〜Ｎ２と同一の放射範囲へ放射される。 However, when the light N from the light emitter 41 enters the non-condensing part 43c, as shown in FIG. 10 (b), the lens part 43 has a uniform thickness so that it functions as a lens. Therefore, the incident light is not collected, and the light rays T1 to T2 emitted from the front lens surface 43a are emitted without going through the lens unit 43 without narrowing the emission range in the horizontal direction. Are emitted to the same radiation range as the light beams N1 and N2.

前記のように、レンズ部４３を介して放射させる光線は、その上下方向への放射範囲を狭くするように集光されてその明るさを大きなものにされると共に、非集光部４３ｃを設けることで水平方向への集光を抑え、光の放射範囲の狭小化を抑制させている。
歩行者や車両の運転手などの標示対象者が通常の移動を行う場合、道路面に対する目の位置の高さが大きく変わることがないため、道路用発光標示体１から発する光線の上下方向の放射範囲を狭めても、その視認性を大きく損なうことがない。また、道路用発光標示体１の発光部４の位置を、標示対象者の目の高さに合わせて設ければ、発光部４からの光線が標示対象者により視認されやすくなり好ましい。
また、反対に標示対象者は道路を通行するとともに水平方向へ移動するので、道路用発光標示体１から発する光は、視認される場所がより大きくなされるように水平方向へ広範囲に放射されるのが好ましい。 As described above, the light rays emitted through the lens unit 43 are condensed so as to narrow the radiation range in the vertical direction to increase the brightness, and the non-condensing unit 43c is provided. This suppresses condensing in the horizontal direction and suppresses the narrowing of the light emission range.
When a target person such as a pedestrian or a vehicle driver moves normally, the height of the eye position relative to the road surface does not change greatly. Even if the radiation range is narrowed, the visibility is not greatly impaired. In addition, it is preferable that the position of the light emitting unit 4 of the light emitting indicator 1 for roads is provided in accordance with the eye level of the person to be marked because the light from the light emitting part 4 is easily recognized by the person to be marked.
On the other hand, since the person to be labeled passes along the road and moves in the horizontal direction, the light emitted from the light-emitting sign 1 for the road is radiated in a wide range in the horizontal direction so that a visible place is made larger. Is preferred.

上記の各実施形態において、発光部４はレンズ部４３を備えた保護カバー部４２内に発光体４１を内装させたユニット体に形成させているが、これに限るものではなく、レンズ部４３の形状が異なってもよく、レンズ部４３を設けない保護カバー部４２内に発光体４１を内装させたユニット体に形成させてもよい。
また、発光部４の内部には、発光体４１を横方向に３個一列に取り付け、これを上下方向に二列配置して合計６個ずつ取り付けているが、発光体４１の配置や取り付ける個数はこれに限るものではなく、横方向の個数や、上下方向の列の数や、合計の個数をそれぞれ変更してもよい。
また、発光部４をユニット体に形成させずに、発光体を直接支柱２に固定させて光を放射させるよう発光部４を設けても良い。
また上記の各実施形態において、支柱２の発光部４の間に反射体５を設けているが、発光部４のみを設けてもよい。 In each of the embodiments described above, the light emitting unit 4 is formed in a unit body in which the light emitting body 41 is housed in the protective cover unit 42 provided with the lens unit 43, but is not limited to this. The shape may be different, and the light emitting body 41 may be formed in a unit body in the protective cover portion 42 where the lens portion 43 is not provided.
In addition, inside the light emitting unit 4, three light emitters 41 are attached in a row in the horizontal direction, and these are arranged in two rows in the vertical direction, for a total of six. Is not limited to this, and the number in the horizontal direction, the number of columns in the vertical direction, and the total number may be changed.
In addition, the light emitting unit 4 may be provided so as to emit light by directly fixing the light emitting unit to the support column 2 without forming the light emitting unit 4 in the unit body.
Further, in each of the above embodiments, the reflector 5 is provided between the light emitting units 4 of the support column 2, but only the light emitting unit 4 may be provided.
