【０００１】
【発明の属する技術分野】
本発明は、簡易にライン状ライトガイドを製造する方法に関する。
【０００２】
【従来の技術】
従来、光学ファイバーを用いたライン状ライトガイドの製造には、光学ファイバーをドラム等に隙間なく巻き付けてシート状とし、そのシートを長形の口金に挟み端面を研磨する、光学ファイバーを１本ずつ引き揃えて接着し、長形の口金に挟み端面を研磨する等の方法がある。
【０００３】
しかしながら、ドラム等に巻き付ける方法では、光学ファイバーの長さ、ライン長に制約があり、また任意のピッチにすることが困難であり、１本ずつ引き揃える方法では、光学ファイバーを所定間隔に接着する或いは必要なライン長を得るのに極めて手間がかかる等の問題がある。
【０００４】
【発明が解決しようとする課題】
本発明の目的は、光学ファイバーを用い、長さに制約がなく、任意のピッチに光学ファイバーを並べた所望のライン長のライン状ライトガイドを簡易に得ることにある。
【０００５】
【課題を解決するための手段】
本発明は、光ファイバーの直径に相当する円の半円形状の溝を複数並設した樹脂製の２個の固定板Ａ、Ｂを対向させて形成されるそれぞれ円形状の溝間に固定治具によって一定挟持幅に制御して光ファイバーを挟持し、固定板Ａ、Ｂを固定して固定ユニットを形成し、固定ユニットをライン状になるよう連結することを特徴とするライン状ライトガイドの製造方法にある。
【０００６】
【発明の実施の形態】
本発明は、光ファイバーの固定ユニットを形成してライン状ライトガイドを製造することにあり、さらに、このユニットを連結して任意の長さのライン状ライトガイドを製造することにある。
【０００７】
光ファイバーの固定ユニットは、光ファイバーの直径に相当する円の半円形状の溝を複数並設した２個の固定板Ａ、Ｂを用い、２個の固定板Ａ、Ｂの溝面を対向させて形成されるそれぞれ向かい合う溝間に光ファイバーを挿入し、溝間にて光ファイバーを挟持してネジ等で両固定板を固定する。また、固定板Ａ、Ｂの一方の溝面の半円形状の各溝に光ファイバーを挿入し、他方の固定板の溝面を対向する半円形状の溝を合わせ、光ファイバーを挟持してネジ等で両固定板を固定してもよい。
【０００８】
特に本発明においては、２個の固定板Ａ、Ｂを予め緩くその溝面をネジ等で固定し、２個の固定板Ａ、Ｂの溝面を合わせて対向して形成される向かい合う溝間がほぼ円形状となるようにしておき、それぞれの溝間に光ファイバーを挿入する方法が好ましく用いられる。
【０００９】
光ファイバーとしてプラスチック光ファイバーを用いるときは、固定板による挟持部分の光ファイバーの一部に予め溶融により太部を形成しておくならば、挿入、固定後の抜け落ちがなく、また容易に挿入作業を行い得る。
【００１０】
また、各溝間で光ファイバーを挟持し固定する際、両固定板は好ましくはネジで固定されるが、固定板の固定により必要以上に光ファイバーを圧縮し変形させないよう２個の固定板を一定間隔に維持する固定板間に内設する板状の幅固定治具、或いは２個の固定板が離反し光ファイバーが抜けないよう固定板間に跨設するかすがい状の幅固定治具によって光ファイバーの挟持幅を制御することが好ましい。これら幅固定治具は、任意の箇所に設置して装着し、そのまま光ファイバー固定ユニットに存在させておくことができる。
【００１１】
固定板としては、好ましくはＡＢＳ樹脂、ポリカーボネート樹脂、ポリプロピレン樹脂等から構成され、一方の面に光ファイバーの直径に相当する円の半円形状の溝が並設されている。固定板は、配列された光ファイバーの端面がライン状を呈することのできる長尺の固定板とし、幅、厚さは、光ファイバーを十分挟持し、強度的に確実に固定しうる範囲であれば特に制限はない。また、固定板は、光ファイバーを挟持し得る範囲であれば、ラインが曲線状となる曲面を有していてもよい。
【００１２】
光ファイバーの固定ユニットは、固定板の溝ピッチを任意に変更し得るので任意のピッチに光ファイバーを配列させることができる。また任意の配列長さのユニットとし得る。光ファイバーが挟持されて露出した光ファイバー端面は、必要により研磨し、光の出射部とし、光ファイバーの他方端は、適宜集束して光源に導かれる。
【００１３】
本発明においては、形成した光ファイバーの固定ユニットを、任意の数、配列ピッチの異なるものまたは配列長さの異なるものを組み合わせて用い、配列する光ファイバー端面が所望の長さのライン状になるよう連結する。光ファイバー固定ユニットの連結は、各ユニットを連結板によりユニットの側面で固定する。また、この光ファイバー固定ユニットは、固定板が樹脂で構成されることにより撓みを有し、連結を施工現場にて行ううえでの作業を容易にする。
【００１４】
本発明においては、かかる光ファイバーの固定ユニットの形成によりライン状ライトガイドを簡易に得ることができ、また固定ユニットの連結により、任意の長さのライン状ライトガイドを容易に得ることができる。得られたライン状ライトガイドは、公知の任意の方法により所定の場所、部位に取り付けることができる。
【００１５】

BACKGROUND OF THE INVENTION
The present invention relates to a method for easily manufacturing a line light guide.
[0002]
[Prior art]
Conventionally, in the production of a line-shaped light guide using an optical fiber, the optical fiber is wound around a drum or the like to form a sheet, the sheet is sandwiched between long bases, and the end face is polished one by one. There are methods such as polishing by aligning and adhering to a long base and polishing the end face.
[0003]
However, in the method of winding around a drum or the like, the length of the optical fiber and the line length are limited, and it is difficult to make an arbitrary pitch. In the method of aligning one by one, the optical fibers are bonded at a predetermined interval. Alternatively, there is a problem that it takes much time to obtain a necessary line length.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to easily obtain a line-shaped light guide having a desired line length in which optical fibers are used, the length is not limited, and optical fibers are arranged at an arbitrary pitch.
[0005]
[Means for Solving the Problems]
The present invention provides a fixing jig between two circular grooves formed by opposing two resin-made fixing plates A and B in which a plurality of circular semicircular grooves corresponding to the diameter of an optical fiber are arranged side by side. A method for manufacturing a line-shaped light guide, characterized in that an optical fiber is clamped by controlling to a certain clamping width , fixing plates A and B are fixed to form a fixing unit, and the fixing units are connected in a line shape. It is in.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
An object of the present invention is to form a linear light guide by forming a fixed unit of an optical fiber, and to manufacture a linear light guide having an arbitrary length by connecting the units.
[0007]
The optical fiber fixing unit uses two fixing plates A and B in which a plurality of circular semicircular grooves corresponding to the diameter of the optical fiber are arranged in parallel, with the groove surfaces of the two fixing plates A and B facing each other. An optical fiber is inserted between the formed grooves facing each other, the optical fiber is sandwiched between the grooves, and both fixing plates are fixed with screws or the like. Further, an optical fiber is inserted into each semicircular groove on one groove surface of the fixing plates A and B, a semicircular groove facing the groove surface of the other fixing plate is aligned, the optical fiber is sandwiched, and a screw or the like Both fixing plates may be fixed with.
[0008]
In particular, in the present invention, the two fixing plates A and B are loosened in advance and their groove surfaces are fixed with screws or the like, and the groove surfaces of the two fixing plates A and B are combined to face each other. A method of inserting an optical fiber between the grooves is preferably used.
[0009]
When using a plastic optical fiber as the optical fiber, if a thick part is formed in advance by melting a part of the optical fiber in the sandwiched portion by the fixing plate, there is no dropout after insertion and fixation, and the insertion operation can be performed easily. .
[0010]
In addition, when the optical fiber is sandwiched and fixed between the grooves, the two fixing plates are preferably fixed with screws, but the two fixing plates are spaced at regular intervals so as not to compress and deform the optical fiber more than necessary by fixing the fixing plate. The plate-shaped width fixing jig provided between the fixed plates to be maintained at the same position, or the narrow width fixing jig straddled between the fixed plates so that the two optical plates are separated and the optical fibers do not come off. It is preferable to control the clamping width. These width fixing jigs can be installed and installed at arbitrary locations, and can be left in the optical fiber fixing unit as they are.
[0011]
The fixing plate is preferably made of ABS resin, polycarbonate resin, polypropylene resin or the like, and a semicircular groove of a circle corresponding to the diameter of the optical fiber is arranged in parallel on one surface. The fixing plate is a long fixing plate in which the end faces of the arranged optical fibers can form a line shape, and the width and thickness are particularly within the range in which the optical fibers can be sufficiently clamped and securely fixed in strength. There is no limit. Further, the fixing plate may have a curved surface with a curved line as long as the optical fiber can be sandwiched.
[0012]
Since the optical fiber fixing unit can arbitrarily change the groove pitch of the fixing plate, the optical fibers can be arranged at an arbitrary pitch. Moreover, it can be set as the unit of arbitrary arrangement | sequence length. The end face of the optical fiber exposed by sandwiching the optical fiber is polished if necessary to form a light emitting portion, and the other end of the optical fiber is appropriately focused and guided to the light source.
[0013]
In the present invention, the optical fiber end units to be arranged are connected in a line shape of a desired length by using an arbitrary number of optical fiber fixing units formed in combination with different arrangement pitches or different arrangement lengths. To do. The optical fiber fixing unit is connected by fixing each unit on the side surface of the unit with a connecting plate. Moreover, this optical fiber fixing unit has a bending | flexion because a fixing plate is comprised with resin, and makes the operation | work in performing a connection in a construction site easy.
[0014]
In the present invention, it is possible to easily obtain a line-shaped light guide by forming such an optical fiber fixing unit, and it is possible to easily obtain a line-shaped light guide having an arbitrary length by connecting the fixing units. The obtained line light guide can be attached to a predetermined place and site by any known method.
[0015]
