Description
【０００１】[0001]
本考案は例えばスポットライト等の舞台照明器具や手術室用の無影灯等に用い られる照明装置に関するものである。 The present invention relates to a lighting device used for stage lighting equipment such as a spotlight or an operating room surgical light.
【０００２】[0002]
従来この種の照明装置としては、例えば、白熱電球、ハロゲン電球等の光源体 から発せられた照明光線を平凸レンズやフレネルレンズからなる透過部材に透過 させ、平凸レンズ、フレネルレンズ等のレンズ作用及び反射鏡により照射光を集 中して或る局部範囲を照明するようにした構造のものが知られている。 Conventionally, as an illumination device of this type, for example, an illumination light beam emitted from a light source body such as an incandescent light bulb or a halogen light bulb is transmitted to a transmissive member including a plano-convex lens and a Fresnel lens, and a lens action such as a plano-convex lens and a Fresnel lens is provided. There is known a structure in which irradiation light is collected by a reflecting mirror to illuminate a certain local area.
【０００３】 そして用途や投光距離により電球の個数、ワット数、レンズの焦点距離などを 選択して使用し、用途、目的に合った効果的な照明が得られるようにしている。The number of light bulbs, the wattage, the focal length of the lens, etc. are selected and used according to the application and the projection distance so that effective illumination suitable for the application and purpose can be obtained.
【０００４】[0004]
しかしながら、上記従来の照明装置は、平凸レンズやフレネルレンズにより集 光作用を得ているため、例えば舞台照明のように遠距離用に平凸レンズを採用し た場合色収差による投光面の着色が生じ易く、またフレネルレンズを採用すると 投光面の周辺部がソフトに拡散し、ハレーションも大きく、不適当であることが あり、また病院の手術室に用いられる無影灯のように比較的短距離用に上記レン ズを採用すると集光作用に伴って集熱作用が生じ、複数の電球を用いて一個当た りの放熱量を小さくしたり、赤外線フィルタをつけたりしているが、長時間の照 明時に温度上昇が生じて好ましくないという不都合を有している。 However, since the above-described conventional lighting device has a plano-convex lens or Fresnel lens for collecting light, when a plano-convex lens is used for a long distance such as stage lighting, the projection surface is colored due to chromatic aberration. It is easy to use, and if a Fresnel lens is used, the periphery of the projection surface will be softly diffused, and halation will be large, which may be inappropriate, and a relatively short distance like the surgical light used in hospital operating rooms. When the above lens is used for light collection, a heat collecting effect occurs due to the light collecting effect, and the heat radiation amount per one is reduced by using multiple light bulbs, and an infrared filter is attached, but it takes a long time. It has the disadvantage that the temperature rises during illumination, which is not desirable.
【０００５】[0005]
本考案はこれらの不都合を解決することを目的とするもので、その要旨は、光 源体から発せられた照明光線を透過させる透過部材を備えてなり、上記透過部材 として光が伝搬する複数個のコア部分とその周辺を覆うクラッド部分からなる光 ファイバ材が用いられていることを特徴とする照明装置にある。 The present invention is intended to solve these inconveniences, and the gist thereof is to include a transmissive member that transmits an illumination light beam emitted from a light source, and a plurality of light transmissive members through which the light propagates. An illuminating device is characterized by using an optical fiber material composed of a core part and a clad part covering the periphery thereof.
【０００６】[0006]
上記の構成により、光源体から発せられた照明光線は透過部材を透過して照射 され、透過部材は光が伝搬する複数個のコア部分とその周辺を覆うクラッド部分 からなる光ファイバ材から構成されているため、照明光線は複数個のコア部分内 で反射を繰り返しつつクラッド部分で閉じ込められた状態で伝搬され照射される ことになる。 With the above configuration, the illumination light beam emitted from the light source body is transmitted through the transmissive member and is irradiated, and the transmissive member is composed of an optical fiber material composed of a plurality of core portions through which light propagates and a clad portion covering the periphery thereof. Therefore, the illumination light beam is propagated and irradiated while being confined in the clad part while being repeatedly reflected in a plurality of core parts.

A light source body 2 made of a halogen bulb is provided in an illuminator body 1 suspended above the stage. Also, the reflector 3 is disposed, and the illumination light L emitted from the light source 2 is transmitted through the transmissive member 4 to locally illuminate it.

Due to the difference in the refractive index of the covering clad portion 4b, the illuminating light beam L is confined by the clad 4b and propagates while being repeatedly reflected in each of the plurality of cores 4a. Therefore, the illumination light emitted from the light source body 2 is emitted. The light rays L are emitted in the form of a bundle of light that has been aligned with each other, and the diffusion of the light is suppressed, so that even local illumination is possible and proper light distribution is also possible. Combined with the dimmer, it is possible to produce effective stage lighting suitable for the scale and purpose.

In this case, the optical fiber material of the first embodiment is constructed by bundling and bonding a plurality of linear optical fibers. However, in the case of the second embodiment, at the time of injection molding, a plurality of members to be the core portions 4a are arranged in parallel in the resin to be the cladding portion 4b, and they are formed by insert molding. is there.
【００１２】 この第二実施例の透過部材４によっても上記第一実施例と同様な作用効果を得 るものである。The transmitting member 4 of the second embodiment also obtains the same effect as that of the first embodiment.
【００１３】 図７の第三実施例は、照明すべき部屋と隣の部屋との境の壁５に上記図４、５ 又は図６の状態の光ファイバ材からなる長尺状の透過部材４を貫通配置し、隣の 部屋に照明器体１を配置するとともに照明器体１の前面に透過部材４の一方端部 を直結配置し、透過部材３の外周面に遮光被覆６を形成し、透過部材４の他方端 部に周縁リング７を配設して構成したものである。In the third embodiment of FIG. 7, a long transparent member 4 made of an optical fiber material in the state of FIG. 4, 5 or 6 is provided on a wall 5 between the room to be illuminated and the adjacent room. And the illuminator body 1 is placed in the adjacent room and one end of the transparent member 4 is directly connected to the front surface of the illuminator body 1, and the light-shielding coating 6 is formed on the outer peripheral surface of the transparent member 3. A peripheral ring 7 is arranged at the other end of the transparent member 4.

Can be increased.
【００１５】 図８の第四実施例は本考案を病院の手術室に用いられる無影灯に適用したもの で、天井から吊り下げられる照明器体１にハロゲン電球、クリプトン電球等から なる複数個の光源体２を配置し、この各々の光源体２の前方に光源体２から発せ られた照明光線Ｌが透過する透過部材４を配置し、この透過部材４を上記図４、 ５又は図６の状態の光ファイバ材により形成して構成されている。A fourth embodiment of FIG. 8 is an application of the present invention to a surgical light used in an operating room of a hospital, in which a plurality of halogen bulbs, krypton bulbs and the like are provided in the illuminator body 1 suspended from the ceiling. The light source bodies 2 are arranged, and a transmissive member 4 through which the illumination light beam L emitted from the light source body 2 passes is disposed in front of each of the light source bodies 2. It is formed by the optical fiber material in the above state.
