次に、本発明の実施形態に係る照明具１について、図を参照して説明する。
図１及び図２に示されるように、本実施形態に係る照明具１は発光体１１と台座１２かなる。
発光体１１は、発光素子１１２を透明な球体形状の被覆体１１１に内蔵しており、互いに直交する三次元の軸周りの回転方向及び回転量に応じて、発光素子１１２の発光方向、発光量、色味のいずれか又は複数を変化させる。 Next, the lighting fixture 1 according to the embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the lighting fixture 1 according to the present embodiment includes a light emitter 11 and a pedestal 12.
The luminous body 11 has the luminous element 112 incorporated in a transparent spherical cover 111, and the luminous direction and luminous amount of the luminous element 112 according to the rotation direction and the amount of rotation about a three-dimensional axis orthogonal to each other. , Change one or more of the colors.

また、この発光体１１は図３に示されるように、外部に光を放出する発光素子１１２、発光体１１の回転方向や回転量を検出するための検出機構１１４、発光体１１の回転方向や回転量に応じて発光素子１１２を制御する制御部１１３、電力の検出機構１１４、制御部１１３、及び発光素子１１２に供給する電力供給機構１１５を有している。   Further, as shown in FIG. 3, the light emitting body 11 includes a light emitting element 112 that emits light to the outside, a detection mechanism 114 for detecting a rotation direction and a rotation amount of the light emitting body 11, a rotation direction of the light emitting body 11, It has a control unit 113 that controls the light emitting element 112 according to the rotation amount, a power detection mechanism 114, a control unit 113, and a power supply mechanism 115 that supplies the light to the light emitting element 112.

発光素子１１２は、発光体１１の内部の中心に備えられており、例えばチップ型のＬＥＤ等によって構成される。
この発光素子１１２は、透明な樹脂からなる被覆体１１１で覆われているが、被覆体１１１が透明であることから、放出する光によって外部を照射することができる。
なお、発光素子１１２は一つに限ることはなく、複数、設けてもよい。発光素子１１２を指向性を有するＬＥＤで構成し、一つのみ設ける場合には、一の方向のみを照らす照明となり、複数設けると共に、全方位に照射方向を向ければ、全体を照らす照明となる。
また、発光素子１１２は、ＬＥＤに限らず、蛍光灯や電球によって構成することもできる。 The light-emitting element 112 is provided at the center inside the light-emitting body 11, and is configured by, for example, a chip-type LED or the like.
The light emitting element 112 is covered with a cover 111 made of a transparent resin. However, since the cover 111 is transparent, the outside can be irradiated with emitted light.
Note that the number of the light emitting elements 112 is not limited to one, and a plurality of light emitting elements may be provided. When the light-emitting element 112 is formed of an LED having directivity and only one light-emitting element is provided, the light is illuminated in only one direction.
Further, the light emitting element 112 is not limited to the LED, and may be configured by a fluorescent lamp or a light bulb.

検出機構１１４は、発光体１１について、互いに直交する三次元の軸周りの回転方向及び回転量を検出する。
この検出機構１１４は例えば、加速度センサや地磁気センサ等、傾きや移動あるいは方角を検出可能な各種のセンサを単独又は組み合わせて実現され、特に限定されない。 The detection mechanism 114 detects a rotation direction and a rotation amount of the light-emitting body 11 about a three-dimensional axis orthogonal to each other.

この制御部１１３は、各種の素子や回路によって実現され、検出機構１１４によって検出された発光体１１の回転方向や回転量に応じた発光素子１１２の発光方向や発光量の設定情報を記憶する設定情報記憶手段や、設定情報に基づいて発光素子１１２に制御信号を送信する制御信号送信手段を構成する。 The control unit 113 is a functional unit that turns on and off the light emitting element 112 and controls the light emitting direction and the light emitting amount of the light emitting element 112 according to the rotation direction and the rotation amount of the light emitting body 11 detected by the detection mechanism 114.
The control unit 113 is implemented by various elements and circuits, and stores setting information of the light emitting direction and the light emitting amount of the light emitting element 112 according to the rotation direction and the rotation amount of the light emitting body 11 detected by the detection mechanism 114. The information storage means and the control signal transmission means for transmitting a control signal to the light emitting element 112 based on the setting information are configured.

ここで、発光体１１の回転方向や回転量に応じた発光素子１１２の制御は例えば、ｘ、ｙ、ｚの三次元の軸方向について、ｘ軸周りに回転させたときは回転量に応じて光量を変え、ｙ軸周りに回転させたときは色味を変え、ｚ軸周りに回転させたときは点灯・消灯を切り替える。
また、発光方向の制御は例えば、三次元の軸方向ごとにプラス方向とマイナス方向を照射する発光素子１１２を設けておき、設定に応じた発光素子１１２を点灯させることで可能となる。また、複数の発光素子１１２を設けて機械的に制御せずとも、指向性を有し、一方向のみを照射する発光素子１１２を用いることで、回転方向に応じて所定の方向を照射するようにすることもできる。 Here, the control of the light-emitting element 112 according to the rotation direction and the rotation amount of the light-emitting body 11 is performed, for example, in the three-dimensional axial direction of x, y, and z according to the rotation amount when rotated around the x-axis. The light amount is changed, the color is changed when rotated around the y-axis, and the light is switched on / off when rotated around the z-axis.
The light emitting direction can be controlled by, for example, providing a light emitting element 112 that emits light in the plus direction and the minus direction for each three-dimensional axial direction and lighting the light emitting element 112 according to the setting. Further, even if a plurality of light emitting elements 112 are provided and the light emitting elements 112 having directivity and irradiating in only one direction are used, the light is emitted in a predetermined direction according to the rotation direction without mechanical control.

なお、電力の供給は、電磁誘導に限らず、磁気共鳴など、他のワイヤレス給電の方式によって構成することができる。
ワイヤレス給電にすることにより、回転方向や回転量が制限されることなく、発光体１１を回転させることができる。 The power supply mechanism 115 is a functional unit that receives power from the power source supply mechanism 121 of the pedestal 12 and supplies power to the detection mechanism 114, the control unit 113, and the light emitting element 112.
Here, the power source supply mechanism 121 of the pedestal 12 and the power supply mechanism 115 of the illuminant 11 are, for example, mechanisms for performing so-called wireless power supply using electromagnetic induction. The power supply mechanism 115 of the body 11 forms a power receiving coil.

被覆体１１１は、発光素子１１２と共に、検出機構１１４、制御部１１３、及び電力供給機構１１５を内部に埋設させた状態に被覆する部材である。
本実施形態において、この被覆体１１１は球状に成形された透明な合成樹脂からなり、内部に埋設させた発光素子１１２の光を外部に放出させることができる。 The cover 111 is a member that covers the light emitting element 112, the detection mechanism 114, the control unit 113, and the power supply mechanism 115 in a state of being embedded therein.
In the present embodiment, the cover 111 is made of a transparent synthetic resin formed into a spherical shape, and can emit light of the light emitting element 112 embedded therein to the outside.

なお、本実施形態では、被覆体１１１は透明であるものとしたが、これに限らず、発光素子１１２が発する光を外部に放出可能であれば、透明でも半透明でもよく、透光性又は光透過性を有する限り、色味を有していてもよい。
また、本実施形態では、被覆体１１１の材料は合成樹脂としたが、これに限らず、一定の形状を維持することができると共に、発光素子１１２が発する光を外部に放出可能とさせられる材質であれば、ガラスや紙などによって構成することもできる。 In the present embodiment, the cover 111 is transparent. However, the present invention is not limited to this, and the cover 111 may be transparent or translucent as long as light emitted from the light emitting element 112 can be emitted to the outside. As long as it has light transmittance, it may have a color.
In the present embodiment, the material of the covering body 111 is a synthetic resin. However, the material is not limited to this, and a material capable of maintaining a constant shape and emitting light emitted from the light emitting element 112 to the outside can be used. If so, it may be made of glass or paper.

台座１２は、発光体１１を載置可能であって、発光体１１に対して電力源を供給する電力源供給機構１２１を有する。
この台座１２には、球状の発光体１１を載置するための載置部１２aが発光体１１側に設けられている。載置部１２aは、内側に向かって凹んだ断面弧状の凹部として構成されており、載置部１２aに発光体１１を載置すると、載置部１２aの表面と球状の発光体１１の一部が略隙間なく当接し、発光体１１を台座１２上に固定的に載置しておくことができる。なお、載置部１２aに発光体１１を載置させた状態において、発光体１１は載置部１２a上を摺動させながら三次元の軸周りに自由に回転させることができる。 The pedestal 12 has a power source supply mechanism 121 on which the light emitter 11 can be placed and which supplies a power source to the light emitter 11.
On the pedestal 12, a mounting portion 12 a for mounting the spherical light emitting body 11 is provided on the light emitting body 11 side. The mounting portion 12a is configured as a concave portion having an arcuate cross section that is recessed inward, and when the light emitting body 11 is mounted on the mounting portion 12a, the surface of the mounting portion 12a and a part of the spherical light emitting body 11 are formed. Can contact with almost no gap, and the luminous body 11 can be fixedly placed on the pedestal 12. In a state where the light emitting body 11 is mounted on the mounting portion 12a, the light emitting body 11 can be freely rotated around a three-dimensional axis while sliding on the mounting portion 12a.

電力源供給機構１２１は、発光体１１を動作させるための動力源を供給する機構であり、外部電源と接続している。
上述の通り、台座１２の電力源供給機構１２１と発光体１１の電力供給機構１１５は例えば、電磁誘導を利用した所謂ワイヤレス給電を行う機構であり、台座１２の電力源供給機構１２１が外部電源と接続する送電コイル、発光体１１の電力供給機構１１５が受電コイルを構成し、これにより誘導電流を生じさせて発光体１１を動作可能とする。 The power source supply mechanism 121 is a mechanism that supplies a power source for operating the light emitting body 11, and is connected to an external power supply.
As described above, the power source supply mechanism 121 of the pedestal 12 and the power supply mechanism 115 of the illuminant 11 are, for example, mechanisms for performing so-called wireless power supply using electromagnetic induction. The power transmission coil to be connected and the power supply mechanism 115 of the light emitting body 11 constitute a power receiving coil, thereby generating an induced current to enable the light emitting body 11 to operate.

以上の構成からなる照明具１の使用について説明する。
ユーザは、台座１２に適宜に設けられている電源スイッチを入れるなどして、外部電源から台座１２へ電力を供給する。
これに応じて、台座１２の電力源供給機構１２１から発光体１１の電力供給機構１１５に電力源が供給されると、電力供給機構１１５は電力源を電力に変換して発光素子１１２、制御部１１３、及び検出機構１１４に電力を供給する。 The use of the lighting fixture 1 having the above configuration will be described.
The user supplies power to the pedestal 12 from an external power supply by turning on a power switch appropriately provided on the pedestal 12 or the like.
In response to this, when a power source is supplied from the power source supply mechanism 121 of the pedestal 12 to the power supply mechanism 115 of the light emitting body 11, the power supply mechanism 115 converts the power source into electric power, and converts the power source into electric power. 113 and the detection mechanism 114.

発光体１１は電力供給開始時の設定に応じて、発光素子１１２を点灯させたり、消灯のままにさせたりする。
ここで、ユーザが発光体１１を三次元の軸周りに回転させると、検出機構１１４は回転方向と回転量を検出し、検出値を制御部１１３に送る。これに応じて制御部１１３は、設定情報を参照して、回転方向と回転量に応じた発光状態に発光素子１１２を制御する。 The light emitter 11 turns on or off the light emitting element 112 according to the setting at the start of power supply.
Here, when the user rotates the light emitting body 11 around the three-dimensional axis, the detection mechanism 114 detects the rotation direction and the rotation amount, and sends the detected value to the control unit 113. In response, the control unit 113 controls the light emitting element 112 to emit light according to the rotation direction and the rotation amount with reference to the setting information.

このような本実施形態に係る照明具１によれば、互いに直交する三次元の軸周りの直感的な回転操作により、回転方向及び回転量に応じて異なる発光状態を得ることができる。   According to the luminaire 1 according to the present embodiment, it is possible to obtain different light emission states according to the rotation direction and the rotation amount by intuitive rotation operations around three-dimensional axes orthogonal to each other.

なお、以上の本実施形態においては、発光体１１の検出機構１１４は加速度センサによるものとしたが、他の例によることもできる。例えば、台座１２側に磁性体を設けると共に、発光体１１内にコイルを設けておき、磁束の定量的な変化から発光体１１の回転方向や回転量を検出し、検出した回転方向や回転量に応じた制御を行うようにすることもできる。   In the above-described embodiment, the detection mechanism 114 of the light emitting body 11 is based on the acceleration sensor. However, another example may be used. For example, a magnetic body is provided on the pedestal 12 side, and a coil is provided in the luminous body 11 to detect a rotation direction and a rotation amount of the luminous body 11 from a quantitative change of a magnetic flux. May be controlled according to the conditions.

この場合、発光体１１の受電用アンテナを設けると共に、台座１２に送電用アンテナを設けてワイヤレス給電を可能にし、発光体１１の傾きに応じて発光体に流れる電圧や電流を変化させて発光体１１の明るさを調整することができる。また、合わせて、電圧や電流の変化に応じて色を変えたり発光方向を変える回路を組み込むことで、明るさのみならず、色味や発光方向を変えることも可能である。   In this case, a power receiving antenna for the light emitting body 11 is provided, and a power transmitting antenna is provided on the base 12 to enable wireless power supply. 11 can be adjusted. In addition, by incorporating a circuit that changes a color or a light emitting direction according to a change in voltage or current, it is possible to change not only brightness but also color or light emitting direction.

また、以上の本実施形態において、発光体１１は台座１２から浮かせるようにしてもよい。
この場合には例えば、図４に示すように、発光体１１と載置部１２内に夫々、互いに反発する極性をもった磁力体１１６、１２２を内蔵させる。発光体１１は、磁力体の反発力によって載置部１２上に浮遊し、下方を照らすこともできる。
なお、磁力体１１６、１２２は永久磁石でも電磁石でもよいが、少なくとも磁力体１２２を電磁石とすることで、台座１２に電力源が供給されることによって磁力体１２２が磁性を帯び、発光体１１が台座１２から浮き上がるといった演出が可能である。 Further, in the above embodiment, the light emitting body 11 may be floated from the pedestal 12.
In this case, for example, as shown in FIG. 4, magnetic bodies 116 and 122 having polarities repelling each other are built in the light emitting body 11 and the mounting section 12, respectively. The luminous body 11 can float on the mounting section 12 by the repulsive force of the magnetic body, and illuminate the lower side.
The magnetic bodies 116 and 122 may be permanent magnets or electromagnets. However, by using at least the magnetic body 122 as an electromagnet, the power source is supplied to the pedestal 12 so that the magnetic body 122 becomes magnetic and the light emitting body 11 becomes An effect such as floating from the pedestal 12 is possible.

また、以上の本実施形態では、照明具１の発光体１１は球状に構成したが、これに限らず、他の形状に構成することもできる。
例えば、図５に示す照明具２の発光体２１のように立方体にしたり、図６に示す照明具３の発光体３１のように正多面体（図６の例では正十二面体）にしたりすることができる。少なくとも、点対称な立体形状であれば、三軸方向ごとに操作感を異ならせることがない。なお、点対称な立体ではないが、正四面体も、三軸方向ごとに操作感を異ならせることがなく、本発明が適用可能な形状となり得る。 Further, in the above-described embodiment, the light-emitting body 11 of the lighting fixture 1 is formed in a spherical shape, but is not limited thereto, and may be formed in another shape.
For example, a cubic shape is formed as the luminous body 21 of the lighting fixture 2 shown in FIG. be able to. At least, as long as it is a point-symmetric three-dimensional shape, the operational feeling does not differ for each of the three axial directions. Although not a point-symmetric solid, a regular tetrahedron can also have a shape to which the present invention can be applied without changing the operational feeling for each of the three axial directions.

なお、発光体２１、３１のように平らな面がある場合には、台座１２のように凹状の載置部１２ａを設ける必要はなく、台座２２、３２の発光体２１、３１載置面を平らにしておいてよいし、台座１２の凹部の形状を、発光体２１、３１の外観形状の一部を象った形状にし、凹部に固定的に載置可能にしてもよい。   In the case where there is a flat surface like the light emitters 21 and 31, it is not necessary to provide the concave mounting portion 12a as the pedestal 12, and the mounting surfaces of the light emitters 21 and 31 of the pedestals 22 and 32 need not be provided. It may be flat, or the shape of the concave portion of the pedestal 12 may be a shape imitating a part of the external shape of the light-emitting bodies 21 and 31 so that the light-emitting body 21 and 31 can be fixedly placed in the concave portion.

以上の本発明については、照明として用いるほか、発光体１１、２１、３１の被覆体１１１、２１１、３１１の表面に発光素子１１２、２１２、３１２から放出される光を部分的に遮る化粧模様を施し、光が壁等に模様を創出するようにしてもよい。例えば、化粧模様として星座模様を施して簡易なプラネタリウムのようにすることもできる。   In the present invention described above, in addition to being used as lighting, a decorative pattern that partially blocks light emitted from the light emitting elements 112, 212, 312 is provided on the surfaces of the coverings 111, 211, 311 of the light emitting bodies 11, 21, 31. The light may create a pattern on a wall or the like. For example, a constellation pattern can be applied as a makeup pattern to make it a simple planetarium.
