Description
本発明は、照明装置に関する。 The present invention relates to a lighting device.
行灯などの古来の照明装置のような雰囲気のある照明を実現するために、意図的に光量を変化させることで光のゆらぎを表現した照明装置が提案されている。例えば、特許文献１および特許文献２では、周囲の空気の流れに応じて光量の調節をおこなう照明装置が開示されている。
上述した照明装置においては、装置周囲の光量を変化させるために、光源自体の調光によって光量の調節をおこなっている。その場合、光源に入力する電圧（または電流）などを時間的に変化させる必要があり、光源に負荷がかかることになる。そのため、光源の寿命が短くなることにつながってしまう。また、光量が下がってしまっている状態が続くと、実使用時には危険となる可能性も生じる。一方で、例えば蛍光ランプのように、光量を変化させることが困難な光源には適用できないという点が問題となっていた。 In the illumination device described above, the amount of light is adjusted by dimming the light source itself in order to change the amount of light around the device. In that case, it is necessary to temporally change the voltage (or current) input to the light source, and a load is applied to the light source. As a result, the life of the light source is shortened. In addition, if the state in which the amount of light has been reduced continues, there is a possibility of danger during actual use. On the other hand, there has been a problem that it cannot be applied to a light source in which it is difficult to change the amount of light, such as a fluorescent lamp.
そこで、本発明は、光源自体の光量を変化させることなく、周囲の光量を変化させて光のゆらぎを表現する照明装置を提供することを目的とする。 Therefore, an object of the present invention is to provide an illuminating device that expresses light fluctuation by changing the amount of ambient light without changing the amount of light of the light source itself.
上述した目的を達成するために、本発明の照明装置は、光源と、透光性の材料で形成された筒形状を有し、前記光源を覆うように回転可能に設けられ、少なくとも周方向で屈折率が異なるカバーと、前記カバーを回転させる駆動部と、周囲空間の空気の流れを検出する風量センサと、前記風量センサで検出した風量に応じて前記カバーの回転数を変化させる制御部と、を備えている。 In order to achieve the above-described object, an illumination device of the present invention has a cylindrical shape formed of a light source and a light-transmitting material, is rotatably provided so as to cover the light source, and at least in the circumferential direction. A cover having a different refractive index, a drive unit that rotates the cover, an air volume sensor that detects an air flow in the surrounding space, and a control unit that changes the rotation speed of the cover according to the air volume detected by the air volume sensor; It is equipped with.
以上、本発明によれば、光源自体の光量を変化させることなく、周囲の光量を変化させて光のゆらぎを表現する照明装置を提供することができる。 As described above, according to the present invention, it is possible to provide an illuminating device that expresses light fluctuation by changing the amount of ambient light without changing the amount of light of the light source itself.
以下に、図１を参照しながら、本発明の照明装置の実施形態について説明する。 Hereinafter, an embodiment of the illumination device of the present invention will be described with reference to FIG.
図１（ａ）は、本発明の実施形態における照明装置の模式的な側面図であり、図１（ｂ）は、カバーおよび光源のみを模式的に示した平面図である。 Fig.1 (a) is a typical side view of the illuminating device in embodiment of this invention, FIG.1 (b) is the top view which showed typically the cover and the light source only.
本発明の照明装置１は、筐体１０の内部に、光源２と、透光性の材料で形成された筒形状を有するカバー３とを備えている。光源２は、筐体１０下部に設置した電源７上に設けられており、その電源７は、後述するような種々の光源２に合わせて変更可能である。カバー３は、光源２を覆うように、筒形状の中心軸を回転軸として回転可能に設けられ、その回転は、カバー３上方に設けられた駆動部４によっておこなわれる（図中の矢印Ｘ参照）。
The illuminating device 1 of the present invention includes a light source 2 and a cover 3 having a cylindrical shape made of a light-transmitting material inside a
カバー３は、屈折率が異なる複数のカバー部材３ａ−３ｆを周方向に連接して設けることで、筒形状を成している。カバー３の材料としては、例えば透明プラスチック材料を用いることができ、それぞれのカバー部材３ａ−３ｆにエポキシ樹脂やシリコン樹脂、高屈折率アクリル樹脂などを用いることで、屈折率を変化させることが可能となる。 The cover 3 has a cylindrical shape by providing a plurality of cover members 3a-3f having different refractive indexes connected in the circumferential direction. As the material of the cover 3, for example, a transparent plastic material can be used, and the refractive index can be changed by using an epoxy resin, a silicon resin, a high refractive index acrylic resin, or the like for each cover member 3a-3f. It becomes.
カバー部材３ａ−３ｆはそれぞれ屈折率が異なっているため、カバー３を透過してきた光源２からの光の光量は周方向で空間的に変化することになる。その様子を、図１（ｂ）に模式的に示す。図中の矢印Ａの数で、カバー部材３ａ−３ｆから透過する光の光量の大きさを表している。 Since the cover members 3a to 3f have different refractive indexes, the amount of light from the light source 2 that has passed through the cover 3 varies spatially in the circumferential direction. This is schematically shown in FIG. The number of arrows A in the figure represents the amount of light transmitted through the cover members 3a-3f.
こうして、光源２からの透過光を空間的に変化させるカバー３が回転することで、装置周囲の所定の方向で受ける光の光量は時間的にも変化することになる。これにより、光源自体を調光することなく照明装置の周囲の光量を変化させ、光のゆらぎを表現することが可能となる。また、このことは、光量の変化が電気的にではなく、機械的に実現されているため、照明装置の安定的な使用にもつながることになる。 Thus, when the cover 3 that spatially changes the transmitted light from the light source 2 rotates, the amount of light received in a predetermined direction around the apparatus also changes with time. As a result, it is possible to change the amount of light around the illumination device without dimming the light source itself, thereby expressing light fluctuation. This also leads to stable use of the lighting device because the change in the amount of light is realized mechanically rather than electrically.
ここで、屈折率の異なる複数の扇状のカバー部材を、カバー３上部を閉塞するように設けて、ほぼ全方位で透過光の光量を変化させるようにするとより効果的である。また、カバー３からの透過光の光量が、周方向だけでなく軸方向にも変化するように、それぞれのカバー部材３ａ−３ｆの屈折率が軸方向にも異なるように形成されていてもよい。それにより、周囲の光量をより不規則に変化させて、さらに自然な光のゆらぎを表現することが可能となる。 Here, it is more effective to provide a plurality of fan-shaped cover members having different refractive indexes so as to close the upper portion of the cover 3 and change the amount of transmitted light in almost all directions. Further, the cover members 3a to 3f may be formed so that the refractive indexes of the cover members 3a to 3f are different in the axial direction so that the amount of transmitted light from the cover 3 changes not only in the circumferential direction but also in the axial direction. . As a result, it becomes possible to change the amount of ambient light more irregularly and express more natural light fluctuations.
さらに、本発明の照明装置１においては、筐体１０の上部に、周囲空間の空気の流れを検出するための風量センサ５が設けられている。風量センサ５としては、熱線式フローセンサなどの市販の気体流量計が使用可能である。
Furthermore, in the illuminating device 1 of this invention, the air quantity sensor 5 for detecting the flow of the air of surrounding space is provided in the upper part of the housing |
風量センサ５で検出した風量の情報は、電圧などの出力信号として、駆動部４の制御をおこなう制御部６へと送られる。制御部６は、その出力信号に応じてカバー３の回転数を変化させるための制御信号を生成して、その制御信号により駆動部４の駆動制御がおこなわれる。具体的には、カバー３は無風状態では一定の回転数で回転しているが、風量センサ５で空気の流れが検出されると、その強弱によって、カバー３の回転数が上下するような制御がおこなわれる。 Information on the air volume detected by the air volume sensor 5 is sent as an output signal such as a voltage to the control unit 6 that controls the drive unit 4. The control unit 6 generates a control signal for changing the rotation speed of the cover 3 according to the output signal, and drive control of the drive unit 4 is performed by the control signal. Specifically, the cover 3 rotates at a constant rotational speed in the absence of wind, but when the air flow is detected by the air volume sensor 5, the control is performed so that the rotational speed of the cover 3 increases or decreases depending on the strength. Is done.
このようにして、周囲の空気の流れに呼応してカバー３の回転数が変化することで、装置周囲の光量が時間的にも不規則に変化し、より自然な光のゆらぎに近づけることが可能となる。 In this way, the rotational speed of the cover 3 changes in response to the flow of ambient air, so that the amount of light around the device changes irregularly in time, and can approach a more natural light fluctuation. It becomes possible.
本発明の照明装置１の光源２としては、ＬＥＤデバイスや複数のＬＥＤデバイスを有するＬＥＤモジュールを用いることができる。また、光源自体の調光制御の必要がないため、光量を調節することが困難な蛍光ランプを使用できることは有利である。もちろん、白熱電球やハロゲンランプなど、その他の様々なタイプの照明用光源を使用することも可能である。 As the light source 2 of the illumination device 1 of the present invention, an LED device or an LED module having a plurality of LED devices can be used. In addition, since it is not necessary to control the dimming of the light source itself, it is advantageous to be able to use a fluorescent lamp in which it is difficult to adjust the amount of light. Of course, various other types of illumination light sources such as incandescent bulbs and halogen lamps can also be used.
本実施形態のカバー３は６つのカバー部材３ａ−３ｆで構成されているが、より多数のカバー部材から構成されていてもよい。さらには、カバー３が円筒形状を有し、屈折率が滑らかに変化するように形成されているとより効果的である。その場合、所望のカバー３は、異なる屈折率を有する複数のプラスチック材料を、金型などを用いて円筒形状に成形することで得ることができる。また、より変化のある照明を実現するために、カバー３に自然石のような凹凸が形成されていてもよい。 The cover 3 of the present embodiment is composed of six cover members 3a-3f, but may be composed of a larger number of cover members. Furthermore, it is more effective if the cover 3 has a cylindrical shape and is formed so that the refractive index changes smoothly. In this case, the desired cover 3 can be obtained by molding a plurality of plastic materials having different refractive indexes into a cylindrical shape using a mold or the like. Moreover, in order to implement | achieve illumination with a change more, the unevenness | corrugation like a natural stone may be formed in the cover 3. FIG.
本発明の照明装置１では、カバー３を交換可能とすることで、前述のような多様な構成のカバー３を用いて様々なパターンの光のゆらぎを簡単に表現でき、それにより、様々なシチュエーションに応じた演出照明が可能となる。また、本発明の照明装置１は、ろうそくや菜種油の代わりとして、例えば提灯や行灯だけでなく、シャンデリアなどの光源としても用いることができ、それにより、電球単体では出すことができない雰囲気を作り出すことが可能となる。 In the lighting device 1 of the present invention, by making the cover 3 replaceable, it is possible to easily express light fluctuations of various patterns by using the cover 3 having various configurations as described above, and thereby various situations. Produce lighting according to The lighting device 1 of the present invention can be used not only as a candle or rapeseed oil, but also as a light source such as a lantern or a lantern, for example, to create an atmosphere that cannot be emitted by a single light bulb. Is possible.
