Description

本発明は、ＬＥＤ照明体、詳しくはＬＥＤを配設した光源体を並べて配置することにより構成されるＬＥＤ照明体に関するものである。   The present invention relates to an LED illuminating body, and more particularly to an LED illuminating body configured by arranging light source bodies on which LEDs are arranged.

従来、既存の蛍光灯に代えてＬＥＤを光源として構成された照明器具が提案されている（例えば、特許文献１）。この照明器具は、細長い板状の基板の一方の面に多数のＬＥＤを配置したもので、既存の蛍光灯照明器具に対応できるようにしたものである。
実用新案登録第３１４２６５２号公報 2. Description of the Related Art Conventionally, there has been proposed a lighting fixture configured using an LED as a light source in place of an existing fluorescent lamp (for example, Patent Document 1). This luminaire has a large number of LEDs arranged on one surface of an elongated plate-like substrate, and can be adapted to existing fluorescent lamp luminaires.
Utility Model Registration No. 3142652

本発明が解決しようとする問題点は、上述の照明器具は、ＬＥＤの外側を透明又は半透明なカバーで覆ってあるもので、ＬＥＤ個々の発光状態が照明器具の外方から視認されるため光る点の集合体のようになり、機械的な照明器具の印象が拭えず癒される照明器具とはかけ離れたものになる恐れがあり、カバーの透明度を落とせばＬＥＤ個々の発光は視認できにくくすることはできるが明るさも低下する問題があった。   The problem to be solved by the present invention is that the above-described lighting fixture is such that the outside of the LED is covered with a transparent or translucent cover, and the light emission state of each LED is visually recognized from the outside of the lighting fixture. It becomes like a collection of shining spots, and the impression of mechanical lighting fixtures may be far away from the lighting fixtures that can be healed without being wiped, and if the transparency of the cover is lowered, the light emission of each LED becomes difficult to see There was a problem that the brightness was reduced.

本発明は、上記問題点を解決し、従来の蛍光灯と同様に面全体で発光しているような自然の発光状態を表示することができるとともに、発光面の大きさを自由に設定できる新しい発想のＬＥＤ照明体を提供することを課題とする。   The present invention solves the above-mentioned problems and can display a natural light emitting state that emits light over the entire surface as in the case of a conventional fluorescent lamp, and a new light emitting surface size that can be freely set. It is an object to provide an idea LED lighting body.

前記課題を解決するために本発明に係るＬＥＤ照明体は、多数の光源体で構成されるＬＥＤ照明体であって、以下の要件を備えることを特徴とする。
（イ）上記光源体の発光面の形状は上記ＬＥＤ照明体の発光面を細分化した発光面と同一形状であること
（ロ）上記光源体の発光面に直交する面にはＬＥＤを配設すること
（ハ）上記光源体には上記ＬＥＤの発光を上記発光面から放射させる反射膜を形成したこと In order to solve the above-mentioned problems, an LED illuminating body according to the present invention is an LED illuminating body composed of a large number of light source bodies, and has the following requirements.
(B) The shape of the light emitting surface of the light source body is the same as the light emitting surface obtained by subdividing the light emitting surface of the LED illuminating body. (B) LEDs are arranged on the surface orthogonal to the light emitting surface of the light source body. (C) The light source body is provided with a reflective film for emitting light emitted from the LED from the light emitting surface.

なお、前記反射膜は任意の色で構成し、光源体の表面から放射される放射光が反射膜の色又はＬＥＤの色を補正する補正色で放射されるようにすることが好ましい。   In addition, it is preferable that the reflective film is formed of an arbitrary color so that radiated light emitted from the surface of the light source body is radiated with a correction color that corrects the color of the reflective film or the color of the LED.

請求項１の発明によれば、発光面に直交する面に配設したＬＥＤの光を光源体の内部で反射させ発光面から発光させるのでＬＥＤの光を小さいながらも面の光に変換し、小さな面の光を連結させることにより大きな発光面を構成することができる。しかもＬＥＤのスポット状の光は面の光に変換されているので、斑のない均一の光を発光するＬＥＤ照明体を実現することができる。   According to the invention of claim 1, since the light of the LED disposed on the surface orthogonal to the light emitting surface is reflected inside the light source body and emitted from the light emitting surface, the light of the LED is converted to light of the surface while being small, A large light emitting surface can be formed by connecting light of a small surface. Moreover, since the spot-like light of the LED is converted into surface light, an LED illuminator that emits uniform light without spots can be realized.

請求項２の発明によれば、反射膜を構成する塗料の色を任意に選択すれば、自由にＬＥＤ照明体の発光する色を設定することができる。また、カラーＬＥＤとの組合せで反射膜を補正色用として選択することによりＬＥＤの色を補正して発光するＬＥＤ照明体を実現することができる。   According to invention of Claim 2, if the color of the coating material which comprises a reflecting film is arbitrarily selected, the color which LED illumination body emits can be set freely. Further, by selecting a reflective film for the correction color in combination with a color LED, it is possible to realize an LED illuminator that emits light by correcting the color of the LED.

図１は本発明に係るＬＥＤ照明体Ａを適用した照明装置Ｂの一例を示し、この照明装置Ｂは多数の光源体１を直線状に並接して構成したＬＥＤ照明体Ａを内装し、光源体１を発光させることによりＬＥＤ照明体Ａが長板状に発光するようにしたもので、照明装置Ｂの上面が透明な筒状の筐体Ｃの内部に収容し、従来の蛍光灯と同様に使用できるようにしたものである。   FIG. 1 shows an example of an illuminating device B to which an LED illuminating body A according to the present invention is applied. The illuminating device B includes an LED illuminating body A constituted by arranging a large number of light source bodies 1 in a straight line, and a light source. The LED illuminating body A emits light in the form of a long plate by causing the body 1 to emit light, and the upper surface of the illuminating device B is accommodated in a transparent cylindrical casing C, which is similar to a conventional fluorescent lamp. It can be used for.

上記光源体１は透明な導光性を有する素材（例えば、アクリル樹脂）を、図２（ａ）に示すように、表面１ａを平面状、背面側１ｂを曲面状にして略カマボコ状に形成したもので、表面１ａに直交する両端面１ｃにはＬＥＤ２（好ましくは、平面実装型のＬＥＤ）を発光面が光源体１の端面１ｃに密着するように接着剤などの適宜手段で固定し、背面側１ｂは塗料を塗布または印刷して反射膜３を構成し、ＬＥＤ２の光を反射膜３で表面側１ａに反射させるようにしたものである（図２（ｂ）参照）。   As shown in FIG. 2A, the light source body 1 is formed of a transparent light-guiding material (for example, an acrylic resin) with a surface 1a having a flat surface and a back surface 1b having a curved surface. Thus, the LED 2 (preferably a planar mounting type LED) is fixed to both end surfaces 1c orthogonal to the surface 1a by an appropriate means such as an adhesive so that the light emitting surface is in close contact with the end surface 1c of the light source body 1, The back side 1b is formed by applying or printing paint to form the reflective film 3, and the light of the LED 2 is reflected by the reflective film 3 to the front side 1a (see FIG. 2B).

なお、この反射膜３を構成する塗料は、光源体１（ＬＥＤ照明体Ａ）をどのような色で発光させるかで決めればよく、白色で発光させたければ白色の塗料を、青色で発光させたければ青色の塗料を塗布すればよく、塗布する塗料の色を選択することにより、発光させたい色を自由に設定することができるようにしてある。さらに、ＬＥＤをカラーＬＥＤにし、反射膜の色を補正色用として選択することによりＬＥＤの色を補正することができる。   The coating material constituting the reflective film 3 may be determined by what color the light source body 1 (LED illuminating body A) emits light. If white light is to be emitted, white paint is emitted in blue. If desired, a blue paint may be applied. By selecting the color of the paint to be applied, the color to be emitted can be freely set. Furthermore, the color of the LED can be corrected by selecting the color LED and selecting the color of the reflective film as the correction color.

この光源体１でＬＥＤ照明体Ａを形成するためには、図３（ａ）（ｂ）に示すように、側面同士を当接した状態で光源体１を図示しない放熱板を兼ねたフレームに固定してＬＥＤの冷却を図るとともに多数の光源体１を連結し、略長板状に形成したＬＥＤ照明体Ａを図１に示すように筐体Ｃの内部に収容すればよい。   In order to form the LED illumination body A with the light source body 1, as shown in FIGS. 3 (a) and 3 (b), the light source body 1 is used as a frame that also serves as a heat sink (not shown) with the side surfaces in contact with each other. The LED illuminating body A formed in a substantially long plate shape may be accommodated in the housing C as shown in FIG.

上記構成のＬＥＤ照明体Ａによれば、光源体１に取り付けたＬＥＤ２を発光させるとＬＥＤ２の光は光源体１の反射膜３で反射し、光源体１の表面１ａから反射膜３の色で放射されるので、この光源体１を並べて配置することにより、長板状の斑のないＬＥＤ照明体Ａを実現することができる。   According to the LED illuminating body A having the above configuration, when the LED 2 attached to the light source body 1 is caused to emit light, the light of the LED 2 is reflected by the reflective film 3 of the light source body 1 and the color of the reflective film 3 from the surface 1a of the light source body 1. Since it radiates | emits, the LED illuminating body A without a long-plate-like spot is realizable by arranging this light source body 1 side by side.

図４（ａ）（ｂ）は、ＬＥＤ照明体Ａの他の例を説明する平面図及び斜視図を示し、このＬＥＤ照明体Ａは平面視略円板状に形成されたもので、光源体１０は、図５（ａ）（ｂ）に示すように、略円錐台状に形成したもので、両端面にはＬＥＤ２を固定し、背面側１０ｂは任意の色の塗料を塗布又は印刷して反射膜３を形成したものである。   4 (a) and 4 (b) show a plan view and a perspective view for explaining another example of the LED illuminating body A. The LED illuminating body A is formed in a substantially disc shape in plan view, and is a light source body. As shown in FIGS. 5 (a) and 5 (b), 10 is formed in a substantially truncated cone shape, the LED 2 is fixed to both end faces, and the back side 10b is coated or printed with any color paint. A reflective film 3 is formed.

上記構成のＬＥＤ照明体Ａによれば、光源体１０に取り付けたＬＥＤ２を発光させれば、ＬＥＤ２の光は光源体１０の反射膜３で反射し、光源体１０の表面１０ａが発光するので、全体として円板状のＬＥＤ照明体Ａを構成することができる。   According to the LED illuminating body A configured as described above, if the LED 2 attached to the light source body 10 is caused to emit light, the light of the LED 2 is reflected by the reflective film 3 of the light source body 10 and the surface 10a of the light source body 10 emits light. The disk-shaped LED illuminating body A can be configured as a whole.

なお、上記光源体１０は、図６（ａ）に示すように、長手方向に２分割し、発光面１０ａ´を平面状にした光源体１０´を形成し、背面１０ｂ´には反射膜３を形成し（図６（ｂ）参照）、図６（ｃ）に示すように、発光面１０ａ´で構成された平坦なＬＥＤ照明体Ａを形成してもよい。   As shown in FIG. 6A, the light source body 10 is divided into two in the longitudinal direction to form a light source body 10 ′ having a light emitting surface 10a ′ in a flat shape, and the reflective film 3 is formed on the back surface 10b ′. (See FIG. 6B), as shown in FIG. 6C, a flat LED illuminating body A constituted by the light emitting surface 10a ′ may be formed.

図７（ａ）は、ＬＥＤ照明体Ａの別の例を示し、このＬＥＤ照明体Ａは略円柱状に形成されたもので、光源体２０は、図７（ｂ）（ｃ）に示すように、長手方向の一端側の端面と他端側と端面とが同じ大きさの略扇状の棒状に形成したもので、両端面にはＬＥＤ２を固定し、前面２０ａは発光面を構成し、背面２０ｂと両側面２０ｃとは任意の色の塗料を塗布又は印刷して反射膜３を形成したものである。   FIG. 7A shows another example of the LED illuminating body A. The LED illuminating body A is formed in a substantially cylindrical shape, and the light source body 20 is as shown in FIGS. 7B and 7C. Further, the end face on the one end side in the longitudinal direction, the other end side, and the end face are formed in a substantially fan-like rod shape, the LED 2 is fixed to both end faces, the front face 20a constitutes a light emitting face, and the back face 20b and both side surfaces 20c are formed by applying or printing a paint of any color to form the reflective film 3.

上記構成の光源体２０を発光面２０ａが連続するように連結し、略円柱状に形成すれば周面が各光源体２０の発光面２０ａで構成された円柱状のＬＥＤ照明体Ａが形成される。   When the light source body 20 having the above configuration is connected so that the light emitting surfaces 20a are continuous and formed in a substantially cylindrical shape, a columnar LED illuminating body A having a peripheral surface constituted by the light emitting surface 20a of each light source body 20 is formed. The

このＬＥＤ照明体ＡのＬＥＤ２を発光させれば、ＬＥＤ２の発光は光源体２０の発光面２０ａから放射されるので全体として円柱の周面が発光するＬＥＤ照明体Ａを構成することができる。   If the LED 2 of the LED illuminating body A is caused to emit light, the light emission of the LED 2 is emitted from the light emitting surface 20a of the light source body 20, so that the LED illuminating body A that emits light from the peripheral surface of the cylinder as a whole can be configured.

図８（ａ）は、ＬＥＤ照明体Ａのさらに他の例を示し、このＬＥＤ照明体Ａは平板状に形成されたもので、光源体３０は、図８（ｂ）に示すように、発光面である表面３０ａが正方形又は長方形状に形成され、縦断面が略Ｔ字状の下窄まりに形成されて脚部３０ｂを構成し、脚部３０ｂの両側にはＬＥＤ２を固定したもので、周面及び底面には任意の色の塗料を塗布又は印刷して反射膜３が形成されている。   FIG. 8A shows still another example of the LED illuminating body A. The LED illuminating body A is formed in a flat plate shape, and the light source body 30 emits light as shown in FIG. 8B. The surface 30a which is a surface is formed in a square or rectangular shape, the longitudinal section is formed in a substantially T-shaped constriction to constitute a leg 30b, and the LED 2 is fixed on both sides of the leg 30b. A reflective film 3 is formed on the peripheral surface and the bottom surface by applying or printing paint of any color.

上記構成の光源体３０を発光面３０ａが連続するように前後左右に連結し、平板状に形成すれば光源体３０の数により任意の大きさの平板なＬＥＤ照明体Ａを形成することができる。   If the light source body 30 having the above configuration is connected to the front and rear, right and left so that the light emitting surface 30a is continuous and is formed in a flat plate shape, a flat LED illuminating body A having an arbitrary size can be formed depending on the number of the light source bodies 30. .

このＬＥＤ照明体ＡのＬＥＤ２を発光させれば、ＬＥＤ２の発光は光源体３０の発光面３０ａから放射されるので全体としてフラットに発光するＬＥＤ照明体Ａを構成することができる。   If the LED 2 of the LED illumination body A emits light, the light emission of the LED 2 is emitted from the light emitting surface 30a of the light source body 30, so that the LED illumination body A that emits light as a whole can be configured.

しかも、光源体を自由に並べることができるので、大きさも形も自由に設定することができる。   In addition, since the light source bodies can be arranged freely, the size and shape can be set freely.

さらに、発光する色を反射膜の色で設定することができるので光源体３０をドットとして、図９（ａ）に示すように連結すれば文字や絵も形成することができ、ＬＥＤの点灯時には光源体３０が面で発光するので、図９（ｂ）に示すように、点の集まりではなく線状に発光するＬＥＤ照明体を構築することができる。   Furthermore, since the light emission color can be set by the color of the reflective film, if the light source 30 is connected as shown in FIG. 9A, characters and pictures can be formed. Since the light source body 30 emits light on the surface, as shown in FIG. 9B, it is possible to construct an LED illumination body that emits light instead of a collection of points.

上述したように、本発明のＬＥＤ照明体Ａは、基板上にＬＥＤを配置したものではなく、ＬＥＤを取り付けた多数の光源体を並接し、光源体の表面（発光面）を連続させることにより大きな発光面を有するＬＥＤ照明体Ａを構成することができ、点で発光するＬＥＤを発光面を有する光源体に固定することにより面で発光する光源に変換し、面で発光する光源体を並接することにより大きな面の発光面を形成することができ、面で発光する優しい光のＬＥＤ照明体Ａを実現することができる。   As described above, the LED illuminating body A of the present invention is not a structure in which LEDs are arranged on a substrate, but a plurality of light source bodies attached with LEDs are juxtaposed and the surface (light emitting surface) of the light source body is made continuous. An LED illuminating body A having a large light emitting surface can be configured, and an LED that emits light at a point is fixed to a light source body having a light emitting surface to convert it to a light source that emits light from the surface, and A large light-emitting surface can be formed by contact, and a gentle light LED illuminator A that emits light from the surface can be realized.

なお、本実施例では光源体の連結構造については言及していないが、接着剤、所定のフレームに固定など適宜の連結手段を用いて連結すればよい。   In addition, although the connection structure of the light source body is not mentioned in the present embodiment, the light source body may be connected by using an appropriate connecting means such as an adhesive or fixing to a predetermined frame.
