JP 2006-79897 A

しかしながら、特許文献１のような照明装置では、消灯時である昼間等に装置自体が目立ち過ぎるため、当該装置の存在により景観が損なわれる可能性がある。   However, in the lighting device as in Patent Document 1, since the device itself is too conspicuous in the daytime when the light is turned off, the scenery may be damaged due to the presence of the device.

本発明は、上記のような課題を解決するためになされたものであり、消灯時に目立たず、その存在により景観が損なわれることのない演出用照明装置を提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an effect lighting device that does not stand out when the lights are turned off and does not impair the scenery due to its presence.

請求項１の発明は、光を照射可能な発光部と、この発光部の上方に設けられ、発光部からの光を上方へと導く導光部と、この導光部の上端に設けられ、導光部によって導かれた光を側方に反射する反射部とを備え、前記発光部は、歩行面より下方に設けられ、前記導光部は、透光性材料により構成されていることを特徴とするものである。   The invention of claim 1 is provided at a light emitting portion capable of irradiating light, a light guide portion provided above the light emitting portion, guiding light from the light emitting portion upward, and an upper end of the light guide portion, A light reflection part that reflects light guided by the light guide part to the side, the light emitting part is provided below the walking surface, and the light guide part is made of a translucent material. It is a feature.

請求項２の発明は、請求項１に記載の演出用照明装置において、前記反射部は、水平面に対して外向きに傾斜する反射面を有することを特徴とするものである。   According to a second aspect of the present invention, in the effect lighting device according to the first aspect, the reflecting portion has a reflecting surface inclined outward with respect to a horizontal plane.

請求項３の発明は、請求項１または２に記載の演出用照明装置において、前記導光部は、上下方向に延びる角柱状に形成されていることを特徴とするものである。   According to a third aspect of the present invention, in the lighting device for production according to the first or second aspect, the light guide portion is formed in a prismatic shape extending in the vertical direction.

請求項４の発明は、請求項１〜３のいずれか一項に記載の演出用照明装置において、前記発光部は、ＬＥＤ発光素子と、このＬＥＤ発光素子を収納する筐体とを有することを特徴とするものである。   Invention of Claim 4 is the illumination device for production | presentation as described in any one of Claims 1-3. WHEREIN: The said light emission part has an LED light emitting element and the housing | casing which accommodates this LED light emitting element. It is a feature.

請求項１の発明によれば、発光部を歩行面より下方に設けたので、歩行者からは発光部が直接見えず、歩行面から導光部が直に立ち上がっているように見える。そして、さらに、導光部を透光性材料で構成したので、消灯状態である昼間には、導光部を通して背景を視認することができ、当該導光部の存在を希薄にすることができる。これらのことから、消灯状態の照明装置を十分目立ちにくくすることができるので、その存在により景観が損なわれるのを防ぐことができる。   According to the first aspect of the present invention, since the light emitting portion is provided below the walking surface, the light emitting portion cannot be directly seen by a pedestrian, and the light guide portion appears to rise up directly from the walking surface. In addition, since the light guide is made of a light-transmitting material, the background can be visually recognized through the light guide during the daytime when the light is off, and the presence of the light guide can be made thin. . From these things, since the lighting apparatus of a light extinction state can be made inconspicuous enough, it can prevent that a landscape is impaired by the presence.

また、上記構成によれば、歩行者が発光部を視認しようと照明装置に近寄って覗き込んだ場合に、歩行者と発光部との間に導光部が配されるため、発光部を視認しにくくなっている。これによっても、照明装置の存在による景観阻害を抑えることができる。   In addition, according to the above configuration, when the pedestrian approaches the lighting device and looks into the light emitting unit so as to visually recognize the light emitting unit, the light guide unit is arranged between the pedestrian and the light emitting unit. It is difficult to do. Also by this, landscape obstruction due to the presence of the lighting device can be suppressed.

請求項２の発明によれば、導光部によって導かれた光を反射面で照明装置の側方に効率良く反射することができるので、点灯時に周辺を明るく照らすことができるようになる。また、この場合、照明装置の点灯時の印象と消灯時の印象とを大きく異ならせることができるようになるので、より演出性を向上させることができるようになる。   According to the second aspect of the present invention, the light guided by the light guide unit can be efficiently reflected to the side of the illuminating device by the reflecting surface, so that the surroundings can be illuminated brightly during lighting. Further, in this case, the impression when the lighting device is turned on and the impression when the lighting device is turned off can be greatly different, so that the performance can be further improved.

請求項３の発明によれば、例えば円柱のように側面が丸みを帯びた形状の導光部の場合と比べて、導光部を通しての背景に歪みが発生しにくくなるので、照明装置をより目立ちにくくすることができるようになる。   According to the third aspect of the present invention, the background through the light guide is less likely to be distorted than in the case of a light guide having a rounded side surface such as a cylinder. You can make it less noticeable.

請求項４の発明によれば、ＬＥＤ発光素子を用いたので、照明装置を小型化することができる。また、この場合、筐体内部に防水用のシリコーン樹脂等を充填することが可能になるので、例えば発光部を地中に埋設する場合に、筐体内の結露を懸念する必要がなくなる。   According to the invention of claim 4, since the LED light emitting element is used, the lighting device can be miniaturized. Further, in this case, since the waterproof silicone resin or the like can be filled in the housing, for example, when the light emitting unit is embedded in the ground, there is no need to worry about dew condensation in the housing.

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明の一実施形態による演出用照明装置の全体構成を示した斜視図であり、図２は、図１に示した演出用照明装置の正面断面図である。   FIG. 1 is a perspective view showing the overall configuration of an effect lighting device according to an embodiment of the present invention, and FIG. 2 is a front sectional view of the effect lighting device shown in FIG.

本実施形態の演出用照明装置１００は、屋外に設置可能なように構成されており、夜間に点灯して周囲を照らすことで演出効果を得るものである。そして、当該照明装置１００は、昼間は消灯状態となっている。   The lighting device for performance 100 according to the present embodiment is configured so as to be installed outdoors, and obtains a performance effect by lighting it at night and illuminating the surroundings. And the said illuminating device 100 is a light extinction state in the daytime.

この演出用照明装置１００は、図１に示すように、地面（歩行面）１０１より下方に位置するように地中に埋設される発光部１と、発光部１の上方に設けられる導光部２と、導光部２の上端に設けられる反射部３とを備えている。   As shown in FIG. 1, the lighting device for effect 100 includes a light emitting unit 1 embedded in the ground so as to be positioned below the ground (walking surface) 101, and a light guide unit provided above the light emitting unit 1. 2 and a reflection part 3 provided at the upper end of the light guide part 2.

発光部１は、上方に向けて光を照射可能なように構成されており、図２に示すように、光源としてのＬＥＤ発光素子１１と、このＬＥＤ発光素子１１を収納する筐体１２とを有している。   The light emitting unit 1 is configured to be able to irradiate light upward. As shown in FIG. 2, an LED light emitting element 11 as a light source and a housing 12 that houses the LED light emitting element 11 are provided. Have.

筐体１２の上面には、ＬＥＤ発光素子１１の光を通過させるための開口１２ａが設けられており、この開口１２ａを覆うように導光部２が配設されている。なお、上記開口１２ａにガラス板等の透光性の板材を嵌め込んで筐体１２の上面を塞ぐとともに、この板材の上面と導光部２の下端面とを接着剤により固定するようにしてもよい。この場合、アクリル樹脂等の透光性に影響を与えにくい樹脂性接着剤を用いるのが好ましい。   An opening 12a for allowing light from the LED light emitting element 11 to pass therethrough is provided on the upper surface of the housing 12, and the light guide portion 2 is disposed so as to cover the opening 12a. A transparent plate material such as a glass plate is fitted into the opening 12a to close the upper surface of the housing 12, and the upper surface of the plate material and the lower end surface of the light guide portion 2 are fixed with an adhesive. Also good. In this case, it is preferable to use a resinous adhesive such as an acrylic resin that hardly affects the translucency.

また、光源としては、上記ＬＥＤ発光素子１１以外の例えば蛍光灯等を用いることもできる。   Further, as the light source, for example, a fluorescent lamp or the like other than the LED light emitting element 11 can be used.

また、図示しないが、筐体１２内には、コネクタ等の給電部品や、この給電部品に電力を供給する電源回路等が収納されており、筐体１２を貫通する配線によって前記電源回路に電力が供給されるようになっている。   Although not shown in the figure, a power supply component such as a connector, a power supply circuit that supplies power to the power supply component, and the like are housed in the housing 12, and power is supplied to the power supply circuit by wiring that penetrates the housing 12. Is to be supplied.

導光部２は、発光部１からの光を上方の反射部３へと導くためのものである。この導光部２は、上下方向に延びる中実な四角柱状に形成されており、その下部が地中に埋没する態様となっている。このため、歩行者からは、導光部２が地面１０１から直に立ち上がっているように見える。   The light guide unit 2 is for guiding the light from the light emitting unit 1 to the upper reflection unit 3. The light guide portion 2 is formed in a solid quadrangular prism shape extending in the vertical direction, and a lower portion thereof is buried in the ground. For this reason, it appears to the pedestrian that the light guide unit 2 stands up directly from the ground 101.

また、本実施形態の導光部２は、透光性材料、例えばガラス等の無機材料や、アクリル樹脂、ポリカーボネート樹脂等の有機材料により構成されている。このように導光部２を透光性材料で構成することによって、当該照明装置１００の消灯状態で、導光部２を通して背景を視認することができ、当該導光部２の存在を希薄にすることができる。   Moreover, the light guide part 2 of this embodiment is comprised by translucent materials, for example, inorganic materials, such as glass, and organic materials, such as an acrylic resin and a polycarbonate resin. By configuring the light guide unit 2 with a light-transmitting material in this way, the background can be visually recognized through the light guide unit 2 when the lighting device 100 is turned off, and the presence of the light guide unit 2 is diluted. can do.

また、導光部２は、発光部１に連結されるその下端が水平な切断面となっているとともに、反射部３に連結されるその上端が反射部３の下面（後述する一対の反射面３１）と密接するように正面視で略Ｖ字の切断面となっている。   The light guide unit 2 has a horizontal cut surface at the lower end connected to the light emitting unit 1, and the lower end of the reflection unit 3 connected to the reflection unit 3 (a pair of reflection surfaces described later). 31) and a substantially V-shaped cut surface in front view.

なお、導光部２は、上記の四角柱状以外に、例えば三角柱状等の多角柱状、円柱状、半円柱状、さらには球状等、任意の形状のものを選択可能であるが、円柱状のように側面が丸みを帯びた形状の場合には、導光部２を通しての背景が歪むことから、景観保護の観点では、丸みのない角柱状であることがより好ましい。ただし、意図的に背景に歪みを演出する場合には、丸みを帯びた形状の導光部であってもよい。   In addition to the above-described rectangular column shape, the light guide unit 2 may be of any shape such as a polygonal column shape such as a triangular column shape, a cylindrical shape, a semi-cylindrical shape, and a spherical shape. In the case where the side surface is rounded as described above, the background through the light guide unit 2 is distorted. Therefore, from the viewpoint of landscape protection, it is more preferable that the prismatic shape is not round. However, when the distortion is intentionally produced in the background, the light guide unit having a rounded shape may be used.

また、導光部２は、中実構造のみならず、中空構造のいわゆる角筒状や円筒状等であってもよい。   Further, the light guide unit 2 may be not only a solid structure but also a so-called rectangular tube shape or a cylindrical shape having a hollow structure.

また、導光部２の外周面や、導光部２が中空構造の場合にはその内周面に、配光制御のための塗装、凹凸処理、それらを施した光学制御シートの貼付等を行ってもよい。このように構成すれば、発光部１からの光をグラデーションさせたり、その輝度の濃淡をランダマイズさせたり、より演出性に富んだ照明環境を提供することができるようになる。   In addition, when the light guide unit 2 has a hollow structure, the outer peripheral surface of the light guide unit 2 is coated with a coating for light distribution control, an uneven surface treatment, and an optical control sheet applied thereto, etc. You may go. If comprised in this way, it will become possible to gradation of the light from the light emission part 1, or to randomize the intensity | strength of the brightness | luminance, and to provide the lighting environment more rich in performance.

反射部３は、正面視で略Ｖ字状に形成されており、導光部２によって導かれた光を側方に反射するものである。この反射部３は、水平面に対して互いに反対側にかつ外向きに傾斜する一対の反射面３１を有しており、これらの反射面３１によって当該照明装置１００の両側方を重点的に照らすことができるようになっている。   The reflection part 3 is formed in a substantially V shape when viewed from the front, and reflects the light guided by the light guide part 2 to the side. The reflecting portion 3 has a pair of reflecting surfaces 31 that are inclined to the opposite sides and outward with respect to the horizontal plane, and the reflecting surfaces 31 illuminate both sides of the lighting device 100 with priority. Can be done.

このような反射部３は、樹脂基板にアルミニウムを蒸着させた汎用のものを用いることができる。   As such a reflection portion 3, a general-purpose one in which aluminum is vapor-deposited on a resin substrate can be used.

また、反射部３は、導光部２の略Ｖ字の上端面に、透光性に影響を与えにくいアクリル樹脂等の樹脂性接着剤により接着されている。   In addition, the reflecting portion 3 is bonded to the substantially V-shaped upper end surface of the light guide portion 2 with a resinous adhesive such as an acrylic resin that hardly affects the translucency.

次に、上記構成の演出用照明装置１００の点灯時および消灯時の各態様について説明する。   Next, each aspect at the time of lighting and extinguishing of the lighting device 100 having the above configuration will be described.

点灯時には、発光部１からの光は、導光部２を通って反射部３に到達し、反射部３の一対の反射面３１によって当該照明装置１００の両側方へと反射される。   At the time of lighting, light from the light emitting unit 1 reaches the reflecting unit 3 through the light guide unit 2 and is reflected by the pair of reflecting surfaces 31 of the reflecting unit 3 to both sides of the lighting device 100.

具体的には、図２に示すように、ＬＥＤ発光素子１１から略真上に発射された光ａは、導光部２内を真っ直ぐ上方に進み、反射部３の一対の反射面３１によって照明装置１００の両側方（図２では左右側方）へと反射される。また、ＬＥＤ発光素子１１から斜め上方に発射された光ｂは、導光部２内を、導光部２の周面（大気との境界面）でほぼ全反射されながら進み、反射部３の一対の反射面３１によって照明装置１００の両側方へと反射される。なお、図示しないが、上記光ｂのうちのごく一部が、導光部２の周面から外部へと進行することによって、導光部２がぼんやりと発光するようになる。   Specifically, as shown in FIG. 2, the light a emitted from the LED light emitting element 11 almost directly travels straight up in the light guide unit 2 and is illuminated by the pair of reflection surfaces 31 of the reflection unit 3. Reflected to both sides of the device 100 (left and right sides in FIG. 2). In addition, the light b emitted obliquely upward from the LED light emitting element 11 travels in the light guide unit 2 while being substantially totally reflected by the peripheral surface of the light guide unit 2 (boundary surface with the atmosphere). The pair of reflecting surfaces 31 are reflected to both sides of the lighting device 100. Although not shown in the drawing, only a part of the light b travels from the peripheral surface of the light guide unit 2 to the outside, so that the light guide unit 2 emits light gently.

一方、消灯時には、透光性材料からなる導光部２を通して背景を容易に視認することができ、当該導光部２の存在が希薄になることから、照明装置１００が十分目立たなくなっている。   On the other hand, when the light is turned off, the background can be easily visually recognized through the light guide portion 2 made of a translucent material, and the presence of the light guide portion 2 becomes dilute, so that the lighting device 100 is not sufficiently conspicuous.

また、歩行者が発光部１を視認しようと照明装置１００に近寄って発光部１に視線を向けた場合、歩行者と発光部１との間に導光部２が配されているため、歩行者が発光部１を視認しにくくなっている。   In addition, when the pedestrian approaches the lighting device 100 and looks at the light emitting unit 1 to visually recognize the light emitting unit 1, the light guide unit 2 is disposed between the pedestrian and the light emitting unit 1. It is difficult for a person to visually recognize the light emitting unit 1.

本実施形態では、上記のように、発光部１を地面１０１より下方に設けたので、歩行者からは発光部１が直接見えず、地面１０１から導光部２が直に立ち上がっているように見える。そして、さらに、導光部２を透光性材料で構成したので、消灯状態である昼間には、導光部２を通して背景を視認することができ、当該導光部２の存在を希薄にすることができる。これらのことから、消灯状態の照明装置１００を十分目立ちにくくすることができるので、その存在により景観が損なわれるのを防ぐことができる。   In the present embodiment, as described above, since the light emitting unit 1 is provided below the ground 101, the light emitting unit 1 is not directly visible to pedestrians, and the light guide unit 2 stands up directly from the ground 101. appear. Further, since the light guide unit 2 is made of a light-transmitting material, the background can be visually recognized through the light guide unit 2 during the daytime when the light is off, and the presence of the light guide unit 2 is diluted. be able to. From these things, since it can make the lighting apparatus 100 of a light extinction state inconspicuous enough, it can prevent that a landscape is impaired by the presence.

また、上記構成の照明装置１００では、歩行者が発光部１を視認しようと照明装置１００に近寄って覗き込んだ場合に、歩行者と発光部１との間に導光部２が配されるため、発光部１を視認しにくくなっている。これによっても、照明装置１００の存在による景観阻害を抑えることができる。   Further, in the lighting device 100 having the above configuration, when the pedestrian approaches the lighting device 100 and looks into the light emitting unit 1 in order to visually recognize the light emitting unit 1, the light guide unit 2 is disposed between the pedestrian and the light emitting unit 1. Therefore, it is difficult to visually recognize the light emitting unit 1. Also by this, landscape obstruction due to the presence of the lighting device 100 can be suppressed.

なお、上記構成の照明装置１００では、導光部２の透光性が十分に高い場合には、反射部３が宙に浮いたように錯覚して見えることも考えられ、これを利用すれば、当該照明装置１００の意匠性を向上することが可能になる。   In addition, in the illumination device 100 having the above-described configuration, when the light guide unit 2 has sufficiently high translucency, it is possible that the reflection unit 3 appears to be floating in the air. It becomes possible to improve the designability of the lighting device 100.

また、本実施形態では、上記のように、水平面に対して外向きに傾斜する反射面３１を有する反射部３を導光部２の上端に設けることによって、導光部２によって導かれた光を反射面３１で照明装置１００の側方に効率良く反射することができるので、点灯時に照明装置１００周辺を明るく照らすことができるようになる。また、この場合、照明装置１００の点灯時の印象と消灯時の印象とを大きく異ならせることができるようになるので、より演出性を向上させることができるようになる。   In the present embodiment, as described above, the light guided by the light guide unit 2 is provided by providing the reflection unit 3 having the reflection surface 31 inclined outward with respect to the horizontal plane at the upper end of the light guide unit 2. Can be efficiently reflected to the side of the illuminating device 100 by the reflecting surface 31, so that the periphery of the illuminating device 100 can be illuminated brightly at the time of lighting. Further, in this case, since the impression when the lighting device 100 is turned on and the impression when the lighting device 100 is turned off can be greatly different, it is possible to further improve the performance.

また、本実施形態では、上記のように、導光部２を上下方向に延びる角柱状に形成することによって、例えば円柱のように側面が丸みを帯びた形状の導光部２の場合と比べて、導光部２を通しての背景に歪みが発生しにくくなるので、照明装置１００をより目立ちにくくすることができるようになる。   Further, in the present embodiment, as described above, the light guide 2 is formed in a prismatic shape extending in the vertical direction, so that, for example, as compared with the case of the light guide 2 having a rounded side surface such as a cylinder. As a result, the background through the light guide 2 is less likely to be distorted, so that the lighting device 100 can be made less noticeable.

また、本実施形態では、上記のように、光源としてＬＥＤ発光素子１１を用いたので、照明装置１００を小型化することができる。また、この場合、筐体１２内部に防水用のシリコーン樹脂等を充填することが可能になるので、筐体１２内の結露を懸念する必要がなくなる。   Moreover, in this embodiment, since the LED light emitting element 11 was used as a light source as mentioned above, the illuminating device 100 can be reduced in size. Further, in this case, since it becomes possible to fill the housing 12 with a waterproof silicone resin or the like, there is no need to worry about dew condensation in the housing 12.

なお、上記実施形態では、演出用照明装置１００を屋外に設置した場合について説明したが、これに限らず、当該照明装置１００を屋内に設置することも可能である。この場合、発光部は歩行面である床面の下方に設けられ、歩行者からは導光部が床面から直に立ち上がっているように見える。   In addition, although the case where the lighting apparatus 100 for production was installed outdoors was demonstrated in the said embodiment, not only this but the said lighting apparatus 100 can also be installed indoors. In this case, the light emitting unit is provided below the floor surface, which is a walking surface, and it appears to the pedestrian that the light guide unit stands up directly from the floor surface.

また、上記実施形態では、正面視で略Ｖ字状の反射部３を設ける例について示したが、これに限らず、図３に示すように、逆四角錐状の反射部４を設けてもよい。この場合、導光部２によって導かれた光を、反射部４の外向きに傾斜する４つの反射面４１で４方に効率良く反射させることができるようになる。   In the above-described embodiment, the example in which the substantially V-shaped reflecting portion 3 is provided in the front view has been described. However, the present invention is not limited thereto, and as illustrated in FIG. Good. In this case, the light guided by the light guide unit 2 can be efficiently reflected in four directions by the four reflection surfaces 41 inclined outward from the reflection unit 4.

また、図４に示すように、逆円錐状の反射部５であってもよい。この場合、導光部２によって導かれた光を、反射部５の外向きに傾斜する反射面５１で周囲に一様に反射させることができるようになる。   Moreover, as shown in FIG. 4, the reflection part 5 of an inverted cone shape may be sufficient. In this case, the light guided by the light guide unit 2 can be uniformly reflected to the periphery by the reflection surface 51 inclined outward from the reflection unit 5.

また、図５に示すように、略平板状の反射部６であってもよい。この場合、導光部２によって導かれた光を、反射部６の下面６１で乱反射させることで周囲を一様に淡く照らすことができるようになる。   Moreover, as shown in FIG. 5, the substantially flat reflection part 6 may be sufficient. In this case, the light guided by the light guide unit 2 is diffusely reflected by the lower surface 61 of the reflection unit 6 so that the surroundings can be uniformly and lightly illuminated.
