以下、本発明の実施形態について説明する。   Hereinafter, embodiments of the present invention will be described.

[照明装置の外観]
図1は、本実施形態に係る照明装置の一例を示す概略外観図である。
[Appearance of lighting device]
FIG. 1 is a schematic external view showing an example of a lighting device according to the present embodiment.

図1に示す照明装置1は、太陽電池2、筐体3、蓄光板4、上面カバー5、制御用筐体6を有する外観構成である。この照明装置1は、不図示の支柱を介して地面に取付けられたり、電柱に取付けられたりする。   The illuminating device 1 shown in FIG. 1 is an external structure which has the solar cell 2, the housing | casing 3, the phosphorescent board 4, the upper surface cover 5, and the housing | casing 6 for control. This illuminating device 1 is attached to the ground via a not-illustrated support or attached to a utility pole.

太陽電池2は、光起電力効果を利用し、自然光(太陽光)を受光して光電変換により直接電力に変換する電力機器である。この太陽電池2は、約5度〜10度傾斜させた筐体3の天面に配設される。天面を傾斜させているのは、雨天時に太陽電池2の上面に付着した水滴が太陽電池2の上面からこぼれ落ちずに太陽電池2の起電効率が低下するのを抑制するためである。この太陽電池2の起電力は、制御用筐体6に収納される蓄電装置(不図示)に蓄えられる。   The solar cell 2 is a power device that uses the photovoltaic effect, receives natural light (sunlight), and converts it directly into electric power by photoelectric conversion. The solar cell 2 is disposed on the top surface of the housing 3 inclined at about 5 to 10 degrees. The reason why the top surface is inclined is to prevent water droplets adhering to the upper surface of the solar cell 2 from spilling from the upper surface of the solar cell 2 and preventing the electromotive efficiency of the solar cell 2 from decreasing when it rains. The electromotive force of the solar cell 2 is stored in a power storage device (not shown) housed in the control housing 6.

筐体3は、直方体状の筐体である。この筐体3の正面(又は、正面及び背面)には蓄光板4が嵌め込まれ、さらに蓄光板4の上面には上面カバー5が覆設される。この筐体3の内部には、発光体11、反射板12、遮光板13等が配設される。筐体3の内部構成については図2等を用いて詳細に後述する。   The housing 3 is a rectangular parallelepiped housing. A phosphorescent plate 4 is fitted on the front surface (or front and rear surfaces) of the housing 3, and an upper surface cover 5 is covered on the upper surface of the phosphorescent plate 4. Inside the housing 3, a light emitter 11, a reflecting plate 12, a light shielding plate 13, and the like are disposed. The internal configuration of the housing 3 will be described later in detail with reference to FIG.

蓄光板4は、自然光や発光体11から発せられた光が照射されてその光エネルギーを吸収し、吸収した光エネルギーを可視光に変換し、光エネルギーの供給が停止した後も一定時間光を放出することにより発光し続ける蓄光性材料を含む平板状の部材である。   The phosphorescent plate 4 is irradiated with natural light or light emitted from the light emitter 11, absorbs the light energy, converts the absorbed light energy into visible light, and emits light for a certain period of time after the supply of light energy stops. It is a flat member containing a phosphorescent material that continues to emit light when emitted.

この蓄光板4は、例えば蓄光材料から成る蓄光層と、蓄光層の上層に形成される透明保護層の2層構成で形成される。蓄光層はアルミン酸ストロンチウムを母結晶とし、これにケイ素、リン、カルシウム、セリウム、ユーロピウム、ディスプロシウム等を添加した材料等によって形成される。一方、透明保護層は、蓄光層の損傷や劣化を防止し、蓄光層からの発光を拡散させて輝度を向上させるべく、透過性の良い透明塗料や透明な紫外線不透過樹脂等によって形成される。   The phosphorescent plate 4 is formed with a two-layer configuration of, for example, a phosphorescent layer made of a phosphorescent material and a transparent protective layer formed on an upper layer of the phosphorescent layer. The phosphorescent layer is formed of a material in which strontium aluminate is used as a mother crystal and silicon, phosphorus, calcium, cerium, europium, dysprosium, or the like is added thereto. On the other hand, the transparent protective layer is formed of a transparent coating material or a transparent ultraviolet opaque resin, etc., in order to prevent damage or deterioration of the luminous layer and to diffuse light emitted from the luminous layer to improve luminance. .

上面カバー5は、蓄光板4の上面に覆設され、蓄光板4を保護するカバー部材である。この上面カバー5は合わせガラス等で形成される。ここでいう合わせガラスとは、複数の板ガラスの間に紫外線不透過性の樹脂等の中間膜を挟んで接着した例えば厚さ6mmの合わせガラスである。   The top cover 5 is a cover member that covers the top surface of the phosphorescent plate 4 and protects the phosphorescent plate 4. The top cover 5 is made of laminated glass or the like. The term “laminated glass” as used herein refers to laminated glass having a thickness of, for example, 6 mm, in which an interlayer film such as an ultraviolet opaque resin is sandwiched between a plurality of plate glasses.

制御用筐体6は、筐体3の下方に隣設される直方体状の筐体である。この制御用筐体6の内部には、太陽電池2の起電力を充電する鉛蓄電池、アルカリ蓄電池等の蓄電装置、蓄電装置による充放電及び発光体11の点灯を制御する制御回路(いずれも不図示)が収納される。   The control housing 6 is a rectangular parallelepiped housing that is provided adjacent to the lower portion of the housing 3. Inside the control housing 6 is a lead storage battery that charges the electromotive force of the solar battery 2, a power storage device such as an alkaline storage battery, a control circuit that controls charging / discharging by the power storage device and lighting of the light emitter 11. (Shown) is stored.

以上に示す構成により、本実施形態に係る照明装置1では、蓄光板4が、自然光や太陽電池2の起電力に基づいて夜間等に点灯するよう制御された発光体11の光を蓄光し、蓄光された光を放出することによって発光を行う。なお、図1及び後述する図2〜図5においては、各構成要素を接続する配線について図示を省略している。   By the structure shown above, in the illuminating device 1 which concerns on this embodiment, the phosphorescent plate 4 accumulates the light of the light-emitting body 11 controlled to light at night etc. based on the natural light or the electromotive force of the solar cell 2, Light is emitted by releasing the stored light. In FIG. 1 and FIGS. 2 to 5 to be described later, wirings for connecting the components are not shown.

[照明装置の内部構成]
図2は、本実施形態に係る照明装置の断面図の一例を示す図である。図2では、図1の断面AA’における筐体3の断面を下方から見た図を示している。
[Internal structure of lighting device]
FIG. 2 is a diagram illustrating an example of a cross-sectional view of the lighting device according to the present embodiment. 2, the figure which looked at the cross section of the housing | casing 3 in the cross section AA 'of FIG. 1 from the downward direction is shown.

図2に示すように、筐体3の内部には、発光体11、反射板12、遮光板13、反射板固定部21が設けられている。   As shown in FIG. 2, a light emitter 11, a reflecting plate 12, a light shielding plate 13, and a reflecting plate fixing portion 21 are provided inside the housing 3.

発光体11は、筐体3の内部側面(ここでは左側面)に配設され、筐体3の内部に向かって光を照射する装置である。この発光体11は、図1に示す制御用筐体6に収納された蓄電装置から放電される電力に基づいて点発光する装置、例えば紫外光を照射する紫外線LEDである。なお、前述の図1では、3個の発光体11を鉛直方向に並べて配置した形態を示しているが、中央の1個のみ設けても良いし、4個以上設けても良い。また、発光体11として紫外線LEDを使用する場合、蓄光板4が吸収する光エネルギーが大きくなるため、蓄光板4における蓄光を効率的に実施することができる。   The light emitter 11 is a device that is disposed on the inner side surface (here, the left side surface) of the housing 3 and emits light toward the inside of the housing 3. The light emitter 11 is a device that performs point emission based on electric power discharged from the power storage device housed in the control housing 6 shown in FIG. 1, for example, an ultraviolet LED that emits ultraviolet light. In FIG. 1, the three light emitters 11 are arranged in the vertical direction, but only one in the center may be provided, or four or more may be provided. Moreover, when using ultraviolet LED as the light-emitting body 11, since the light energy which the phosphorescent plate 4 absorbs becomes large, the phosphorescence in the phosphorescent plate 4 can be implemented efficiently.

反射板12は、筐体3の内部背面左端から内部正面右端に向かって斜めに配設され、発光体11から発せられた光を蓄光板4の裏面に照射させるための反射板である。この反射板12は、例えば片面(ここでは蓄光板4側の面)が鏡面仕上げされたステンレスやアルミニウム等で形成される。この反射板12は、発光体11から遠ざかるに従って蓄光板4との距離が近くなるよう構成されている。そのため、蓄光板4の各位置に到達する光の光路長の差を小さくすることができる。   The reflection plate 12 is a reflection plate that is disposed obliquely from the inner rear left end of the housing 3 toward the inner front right end, and irradiates the back surface of the phosphorescent plate 4 with light emitted from the light emitter 11. The reflecting plate 12 is formed of, for example, stainless steel or aluminum whose one surface (here, the surface on the phosphorescent plate 4 side) is mirror-finished. The reflector 12 is configured such that the distance from the phosphorescent plate 4 decreases as the distance from the light emitter 11 increases. Therefore, the difference in the optical path length of the light reaching each position of the phosphorescent plate 4 can be reduced.

遮光板13は、筐体3の内部において発光体11と蓄光板4の左側端4aとの間に配設され、発光体11から発せられた光を遮光するための部材である。この遮光板13が設けられる理由は、発光体11から発せられた光が蓄光板4の左側端側に直接照射されて、蓄光板4の左右で蓄光量のバラつきが発生するのを防ぐためである。この遮光板13は、反射板12と同様に、例えば鏡面仕上げされたステンレスやアルミニウム等で形成され、遮光機能とともに反射機能を有する。   The light shielding plate 13 is disposed between the light emitter 11 and the left end 4 a of the phosphorescent plate 4 inside the housing 3 and is a member for shielding light emitted from the light emitter 11. The reason why the light shielding plate 13 is provided is to prevent the light emitted from the light emitter 11 from being directly irradiated on the left end side of the phosphorescent plate 4 and causing the accumulated light amount to vary between the left and right sides of the phosphorescent plate 4. is there. The light shielding plate 13 is formed of, for example, mirror-finished stainless steel, aluminum, or the like, similar to the reflecting plate 12, and has a reflection function as well as a light shielding function.

反射板固定部21は、筐体3の内部において反射板12の両側端に配設され、反射板12を固定するための部材である。この反射板固定部21には、例えばステンレス等のネジによって固定される。また、反射板固定部21に対するネジの締め付け量により反射板12の角度を調整することができる。   The reflecting plate fixing portion 21 is a member for fixing the reflecting plate 12, which is disposed on both side ends of the reflecting plate 12 inside the housing 3. The reflector plate fixing portion 21 is fixed with a screw such as stainless steel. Further, the angle of the reflection plate 12 can be adjusted by the amount of tightening of the screw with respect to the reflection plate fixing portion 21.

以上に示すように、本実施形態に係る筐体3の内部には、発光体11と、発光体11から発せられた光を蓄光板4の裏面に照射させるための反射板12と、発光体11と蓄光板4の側端4aとの間に配設され、発光体11から発せられた光を遮光するための遮光板13とが配設される。このように、反射板12と遮光板13とを配設する簡易な構成により、発光体11から照射される光を、効率良く且つ蓄光板4の全面でバラつきが発生しないよう均一に照射させることができる。   As described above, inside the housing 3 according to this embodiment, the light emitter 11, the reflector 12 for irradiating the back surface of the phosphorescent plate 4 with the light emitted from the light emitter 11, and the light emitter 11 and a side edge 4a of the phosphorescent plate 4, and a light shielding plate 13 for shielding light emitted from the light emitter 11 is disposed. In this way, with the simple configuration in which the reflecting plate 12 and the light shielding plate 13 are disposed, the light emitted from the light emitter 11 can be efficiently irradiated uniformly so that no variation occurs on the entire surface of the phosphorescent plate 4. Can do.

また、発光体11が紫外線LEDである場合には、上面カバー5を紫外線不透過性の中間膜を挟んだ合わせガラスとすることにより、紫外線が照明装置1の外部に照射されることを防ぐことができる。   Further, when the light emitter 11 is an ultraviolet LED, the upper cover 5 is made of laminated glass with an ultraviolet-impermeable intermediate film interposed therebetween, thereby preventing ultraviolet rays from being irradiated outside the illumination device 1. Can do.

なお、図1や図2に示す反射板12は平板状に形成されているが、このような形状に限定されるものではない。例えば、この反射板12を、発光体11から遠ざかるに従って蓄光板4との距離が指数関数的に近くなる形状、すなわち反射板12の右端側に向かうほど指数関数的な変化特性を有する屈曲形状に調整しても良い。これにより、反射板11に入射した光が、蓄光板4の全面に均一な強度で導かれるように調整することができる。   In addition, although the reflecting plate 12 shown in FIG.1 and FIG.2 is formed in flat form, it is not limited to such a shape. For example, the reflecting plate 12 has a shape in which the distance from the phosphorescent plate 4 decreases exponentially as the distance from the light emitter 11 increases, that is, a bent shape having an exponential change characteristic toward the right end side of the reflecting plate 12. You may adjust it. Thereby, it can adjust so that the light which injected into the reflecting plate 11 may be guide | induced to the whole surface of the phosphorescent plate 4 with uniform intensity | strength.

また、図2に示す遮光板13は平板状に形成されているが、このような形状に限定されるものではない。例えば発光体11を囲うような円弧状の形状又は円弧状の形状を円の中心を軸に所定角度(例えば180度)回転させた形状に構成しても良い。さらに、遮光板13の傾きや配置する高さを調整することにより、蓄光板4の左右間で蓄光量のバラつきが発生しないようにすることが望ましい。例えば遮光板13の傾きについては、反射板12の反射状況による蓄光板4の明るさの位置の移動状況により調整し、遮光板13の配置する高さについては、遮光による影の状況に応じて遮光板13をカットすることによって適宜調整する。   Moreover, although the light shielding plate 13 shown in FIG. 2 is formed in a flat plate shape, it is not limited to such a shape. For example, an arc shape that surrounds the light emitter 11 or an arc shape that is rotated by a predetermined angle (for example, 180 degrees) about the center of the circle may be configured. Furthermore, it is desirable that the stored light amount does not vary between the left and right sides of the phosphorescent plate 4 by adjusting the inclination and the height of the light shielding plate 13. For example, the inclination of the light shielding plate 13 is adjusted according to the movement state of the brightness position of the phosphorescent plate 4 according to the reflection state of the reflecting plate 12, and the height at which the light shielding plate 13 is arranged depends on the shadow state due to the light shielding. The light shielding plate 13 is appropriately adjusted by cutting.

[第1変形例]
図3は、本実施形態に係る照明装置の第1変形例を示す図である。図3では、図1の断面AA’における筐体3の断面を下方から見た図を示している。
[First Modification]
FIG. 3 is a diagram illustrating a first modification of the lighting device according to the present embodiment. 3, the figure which looked at the cross section of the housing | casing 3 in the cross section AA 'of FIG. 1 from the downward direction is shown.

図3に示す第1変形例では、図2に示す場合と異なり、筐体3の正面及び背面の両方に蓄光板4、上面カバー5が設けられ、筐体3の内部の左右両側面に発光体11が配設されている。また、第1変形例に係る反射板22は、図2に示す反射板12と異なり、両面が鏡面仕上げされる。   In the first modification shown in FIG. 3, unlike the case shown in FIG. 2, a phosphorescent plate 4 and a top cover 5 are provided on both the front and back of the housing 3, and light is emitted on both the left and right sides inside the housing 3. A body 11 is disposed. Further, unlike the reflecting plate 12 shown in FIG. 2, the reflecting plate 22 according to the first modification is mirror-finished on both sides.

以上に示すように、第1変形例に係る筐体3の内部には、2組の発光体11と、発光体11から発せられた光を蓄光板4の裏面に照射させるための反射板22と、発光体11と蓄光板4の側端4aとの間に配設され、発光体11から発せられた光を遮光するための2組の遮光板13とが配設される。このように、反射板22と遮光板13とを配設する簡易な構成により、発光体11から照射される光を、効率良く且つ蓄光板4の全面でバラつきが発生しないよう均一に照射させることができる。   As described above, inside the housing 3 according to the first modification, two sets of the light emitters 11 and the reflection plate 22 for irradiating the back surface of the phosphorescent plate 4 with the light emitted from the light emitters 11. And two sets of light shielding plates 13 are disposed between the light emitter 11 and the side end 4a of the phosphorescent plate 4 and shield light emitted from the light emitter 11. In this way, with the simple configuration in which the reflecting plate 22 and the light shielding plate 13 are disposed, the light irradiated from the light emitter 11 is efficiently irradiated uniformly so that no variation occurs on the entire surface of the phosphorescent plate 4. Can do.

なお、図3に示す反射板22は一枚の平板によって構成されているが、このような構成に限定されるものではない。例えば二枚の反射板を配設し、各々の反射板を、発光体11から遠ざかるに従って蓄光板4との距離が指数関数的に近くなる形状に調整しても良い。これにより、反射板11に入射した光が、二枚の蓄光板4の全面に均一な強度で導かれるように調整することができる。   In addition, although the reflecting plate 22 shown in FIG. 3 is comprised by one flat plate, it is not limited to such a structure. For example, two reflecting plates may be provided, and each reflecting plate may be adjusted to a shape in which the distance from the phosphorescent plate 4 becomes exponentially closer as the distance from the light emitter 11 increases. Thereby, it can adjust so that the light which injected into the reflecting plate 11 may be guide | induced to the whole surface of the two phosphorescent plates 4 with uniform intensity | strength.

[第2変形例]
図4は、本実施形態に係る照明装置の第2変形例を示す図である。図4では、図1の断面AA’における筐体3の断面を下方から見た図を示している。
[Second Modification]
FIG. 4 is a diagram illustrating a second modification of the lighting device according to the present embodiment. 4, the figure which looked at the cross section of the housing | casing 3 in the cross section AA 'of FIG. 1 from the downward direction is shown.

図4に示す第2変形例では、図2に示す場合と異なり、筐体3の内部の左右両側面に発光体11が配設されている。また、第2変形例に係る反射板23は、図2に示す反射板12と異なり、中央に向かうほど蓄光板4との距離が近くなる凸形状に構成される。   In the second modification shown in FIG. 4, unlike the case shown in FIG. 2, the light emitters 11 are arranged on the left and right side surfaces inside the housing 3. Further, unlike the reflector 12 shown in FIG. 2, the reflector 23 according to the second modification is configured in a convex shape such that the distance from the phosphorescent plate 4 becomes closer toward the center.

以上に示すように、第2変形例に係る筐体3の内部には、1対の発光体11と、発光体11から発せられた光を蓄光板4の裏面に照射させるための反射板23と、発光体11と蓄光板4の側端4aとの間に配設され、発光体11から発せられた光を遮光するための1対の遮光板13とが配設される。このように、反射板23と遮光板13とを配設する簡易な構成により、発光体11から照射される光を、効率良く且つ蓄光板4の全面でバラつきが発生しないよう均一に照射させることができる。   As described above, inside the housing 3 according to the second modification, a pair of light emitters 11 and a reflector plate 23 for irradiating the back surface of the phosphorescent plate 4 with light emitted from the light emitters 11. And a pair of light shielding plates 13 disposed between the light emitter 11 and the side end 4a of the phosphorescent plate 4 for shielding the light emitted from the light emitter 11. In this way, with a simple configuration in which the reflecting plate 23 and the light shielding plate 13 are disposed, the light emitted from the light emitter 11 is efficiently irradiated uniformly so that no variation occurs on the entire surface of the phosphorescent plate 4. Can do.

なお、図4に示す反射板23は三角形状に形成されているが、このような形状に限定されるものではない。例えば、この反射板23を、両端の発光体11から遠ざかって筐体3の中央に向かうに従って蓄光板4との距離が指数関数的に近くなる形状に調整しても良い。これにより、反射板23に入射した光が、蓄光板4の全面に均一な強度で導かれるように調整することができる。   In addition, although the reflecting plate 23 shown in FIG. 4 is formed in the triangle shape, it is not limited to such a shape. For example, the reflecting plate 23 may be adjusted to a shape in which the distance from the phosphorescent plate 4 becomes exponentially closer toward the center of the housing 3 away from the light emitters 11 at both ends. Thereby, it can adjust so that the light which injected into the reflecting plate 23 may be guide | induced to the whole surface of the phosphorescent plate 4 with uniform intensity | strength.

図5は、本実施形態に係る照明装置の他の一例を示す図である。
[Another example of lighting device]
FIG. 5 is a diagram illustrating another example of the illumination device according to the present embodiment.

図5(a)及び図5(b)に示す照明装置51は、駐車場等に設置される車輪止め50に組み込まれるものである。図5(b)は、図5(a)の断面BB’における車輪止め50の断面を側方から見た図を示している。   The illuminating device 51 shown to Fig.5 (a) and FIG.5 (b) is integrated in the wheel stopper 50 installed in a parking lot etc. FIG. FIG. 5B shows a side view of the cross section of the wheel stopper 50 in the cross section BB ′ of FIG.

車輪止め50は、基本的にコンクリート、樹脂等の一定強度を確保できる材料によって形成されるが、図5(b)に示すように各種構成要素を内部に配設するための中空空間が形成される。   The wheel stopper 50 is basically formed of a material that can ensure a certain strength, such as concrete and resin, but as shown in FIG. 5B, a hollow space for arranging various components therein is formed. The

図5(a)及び図5(b)に示すように、照明装置51は、太陽電池52、天面カバー53、蓄光板54、上面カバー55、制御部56、蓄電部57、発光体58、反射板59及び遮光板60を有する構成である。   As shown in FIGS. 5A and 5B, the lighting device 51 includes a solar cell 52, a top cover 53, a phosphorescent plate 54, a top cover 55, a control unit 56, a power storage unit 57, a light emitter 58, In this configuration, the reflection plate 59 and the light shielding plate 60 are provided.

太陽電池52は、光起電力効果を利用し、自然光(太陽光)を受光して光電変換により直接電力に変換する電力機器である。この太陽電池52は、約5度〜10度傾斜させた車輪止め50の天面に配設される。天面を傾斜させているのは、雨天時に太陽電池52に覆設される天面カバー53の上面に付着した水滴が天面カバー53の上面からこぼれ落ちずに太陽電池52の起電効率が低下するのを抑制するためである。この太陽電池52の起電力は蓄電部57に蓄えられる。   The solar cell 52 is a power device that uses the photovoltaic effect, receives natural light (sunlight), and directly converts it into electric power by photoelectric conversion. The solar cell 52 is disposed on the top surface of the wheel stopper 50 inclined at about 5 to 10 degrees. The top surface is inclined because water droplets adhering to the top surface of the top surface cover 53 that covers the solar cell 52 in the rain do not spill from the top surface of the top surface cover 53 and the photovoltaic efficiency of the solar cell 52 is reduced. This is to suppress this. The electromotive force of the solar cell 52 is stored in the power storage unit 57.

天面カバー53は、太陽電池52の上面に覆設され、太陽電池52を保護するカバー部材である。この上面カバー5は合わせガラス等の強化ガラスで形成される。   The top cover 53 is a cover member that covers the top surface of the solar cell 52 and protects the solar cell 52. The upper surface cover 5 is formed of tempered glass such as laminated glass.

蓄光板54は、自然光や発光体58から発せられた光が照射されてその光エネルギーを吸収し、吸収した光エネルギーを可視光に変換し、光エネルギーの供給が停止した後も一定時間光を放出することにより発光し続ける蓄光性材料を含む平板状の部材である。蓄光板54の詳細については、図1の蓄光板4と同様であるためここでは説明を省略する。   The phosphorescent plate 54 is irradiated with natural light or light emitted from the light emitter 58 to absorb the light energy, converts the absorbed light energy into visible light, and emits light for a certain period of time after the supply of light energy stops. It is a flat member containing a phosphorescent material that continues to emit light when emitted. The details of the phosphorescent plate 54 are the same as those of the phosphorescent plate 4 of FIG.

上面カバー55は、蓄光板54の上面に覆設され、蓄光板54を保護するカバー部材である。この上面カバー55は合わせガラス等で形成される。ここでいう合わせガラスとは、複数の板ガラスの間に紫外線不透過性の樹脂等の中間膜を挟んで接着した例えば厚さ6mmの合わせガラスである。   The top cover 55 is a cover member that covers the top surface of the phosphorescent plate 54 and protects the phosphorescent plate 54. This upper surface cover 55 is formed of laminated glass or the like. The term “laminated glass” as used herein refers to laminated glass having a thickness of, for example, 6 mm, in which an interlayer film such as an ultraviolet opaque resin is sandwiched between a plurality of plate glasses.

制御部56は、車輪止め50の背面側の内部空間に形成され、プログラム可能なIC等の電子素子を搭載し、蓄電部57に収納される蓄電装置(不図示)の充放電や発光体58の点灯制御を行う制御回路が収納される。   The control unit 56 is formed in an internal space on the back side of the wheel stopper 50 and is equipped with an electronic element such as a programmable IC, and charging / discharging of a power storage device (not shown) housed in the power storage unit 57 and a light emitter 58. A control circuit for controlling the lighting is stored.

蓄電部57は、車輪止め50の背面側の内部空間に形成され、太陽電池52の起電力を充電する蓄電装置、例えばキャパシタやバッテリーが収納される。また、蓄電部57に収納された蓄電装置は、制御部56に収納された制御回路を介して電力を発光体58に供給する。   The power storage unit 57 is formed in the internal space on the back side of the wheel stopper 50, and stores a power storage device that charges the electromotive force of the solar cell 52, such as a capacitor or a battery. The power storage device housed in the power storage unit 57 supplies power to the light emitter 58 via the control circuit housed in the control unit 56.

発光体58は、車輪止め50に形成された内部空間70の背面側上端部に配設され、内部空間70に向かって光を照射する装置である。この発光体58は、蓄電部57に収納された蓄電装置から放電される電力に基づいて点発光する装置、例えば紫外光を照射する紫外線LEDである。この発光体58は、必要に応じて2個以上配設しても良い。なお、発光体58として紫外線LEDを使用する場合、蓄光板54が吸収する光エネルギーが大きくなるため、蓄光板54における蓄光を効率的に実施することができる。   The light emitter 58 is a device that is disposed at the upper end on the back side of the internal space 70 formed in the wheel stopper 50 and irradiates light toward the internal space 70. The light emitter 58 is a device that performs point emission based on electric power discharged from the power storage device housed in the power storage unit 57, for example, an ultraviolet LED that emits ultraviolet light. Two or more light emitters 58 may be provided as necessary. In addition, when using ultraviolet LED as the light-emitting body 58, since the light energy which the light storage board 54 absorbs becomes large, the light storage in the light storage board 54 can be implemented efficiently.

反射板59は、内部空間70の背面側上端部から正面側下端部に沿って配設され、発光体58から発せられた光を蓄光板54の裏面に照射させるための反射板である。この反射板59は、例えば蓄光板54側の面が鏡面仕上げされたステンレスやアルミニウム等で形成される。なお、この反射板59の形状を、図2に示す反射板12と同様に、発光体11から遠ざかるに従って蓄光板4との距離が指数関数的に近くなる屈曲形状に調整しても良い。   The reflection plate 59 is a reflection plate that is disposed along the front-side lower end portion from the rear-side upper end portion of the internal space 70 and that irradiates the back surface of the phosphorescent plate 54 with light emitted from the light emitter 58. The reflecting plate 59 is formed of, for example, stainless steel or aluminum whose surface on the phosphorescent plate 54 side is mirror-finished. The shape of the reflecting plate 59 may be adjusted to a bent shape in which the distance from the phosphorescent plate 4 decreases exponentially as the distance from the light emitter 11 increases, as with the reflecting plate 12 shown in FIG.

遮光板60は、内部空間70において発光体58と蓄光板54の側端54aとの間に配設され、発光体58から発せられた光を遮光するための部材である。この遮光板60が設けられる理由は、発光体58から発せられた光が蓄光板54の側端側(図5(b)では左上端側)に直接照射されて、蓄光板54の面方向で蓄光量のバラつきが発生するのを防ぐためである。この遮光板60は、反射板59と同様に、例えば鏡面仕上げされたステンレスやアルミニウム等で形成され、遮光機能とともに反射機能を有する。   The light shielding plate 60 is disposed between the light emitter 58 and the side end 54 a of the phosphorescent plate 54 in the internal space 70 and is a member for shielding light emitted from the light emitter 58. The reason why the light shielding plate 60 is provided is that light emitted from the light emitter 58 is directly irradiated on the side end side of the phosphorescent plate 54 (the upper left end side in FIG. 5B), and in the surface direction of the phosphorescent plate 54. This is to prevent the accumulated light quantity from varying. Similar to the reflection plate 59, the light shielding plate 60 is made of, for example, mirror-finished stainless steel or aluminum, and has a light shielding function and a reflection function.

以上に示す構成により、他の例に係る照明装置51が組み込まれた車輪止め50では、蓄光板54が、自然光や太陽電池52の起電力に基づいて夜間等に点灯するよう制御された発光体58の光を蓄光し、蓄光された光を放出することによって発光を行う。   With the structure shown above, in the wheel stopper 50 in which the lighting device 51 according to another example is incorporated, the phosphorescent plate 54 is controlled to be lit at night based on natural light or the electromotive force of the solar battery 52. Light is emitted by storing 58 light and emitting the stored light.

以上に示すように、本実施形態に係る照明装置51は、発光体58と、発光体58から発せられた光を蓄光板54の裏面に照射させるための反射板59と、発光体58と蓄光板54の側端54aとの間に配設され、発光体58から発せられた光を遮光するための遮光板60とが配設される。このように、反射板59と遮光板60とを配設する簡易な構成により、発光体58から照射される光を、効率良く且つ蓄光板54の全面でバラつきが発生しないよう均一に照射させることができる。   As described above, the illuminating device 51 according to the present embodiment includes the light emitter 58, the reflector 59 for irradiating the back surface of the phosphorescent plate 54 with the light emitted from the phosphor 58, the light emitter 58, and the phosphorescent. A light shielding plate 60 is disposed between the side end 54a of the plate 54 and shields the light emitted from the light emitter 58. In this way, with the simple configuration in which the reflection plate 59 and the light shielding plate 60 are disposed, the light emitted from the light emitter 58 can be efficiently and evenly irradiated so that no variation occurs on the entire surface of the phosphorescent plate 54. Can do.
