Description

本発明は、照明装置に関し、特に冷陰極発光体を採用した照明装置に関する。   The present invention relates to a lighting device, and more particularly to a lighting device employing a cold cathode light emitter.

従来の照明装置としては、一般的には、主にガス放電により発光する蛍光ランプ管が多く採用されていたが、省電力の発光ダイオード(Light Emitting Diode、LEDと略す)の普及につれて、多くの照明装置において発光ダイオードが光源として採用されるようになりつつある。
また、近年では冷陰極発光体を用いた照明装置が採用されるようにもなってきた(例えば、特許文献1参照)。
In general, fluorescent lamp tubes that emit light mainly by gas discharge have been widely used as conventional lighting devices. However, with the spread of power-saving light emitting diodes (abbreviated as LEDs), Light emitting diodes are being adopted as light sources in lighting devices.
In recent years, lighting devices using cold cathode light emitters have been adopted (see, for example, Patent Document 1).

特開平2−82406号公報(第3ページ上段左欄第4行〜第12行、第1図及び第3図)Japanese Patent Laid-Open No. 2-82406 (the third column, upper left column, lines 4 to 12, lines 1 and 3)

一般の発光ダイオードを光源とする照明装置は、従来の蛍光ランプ管より高い発光効率と輝度を有するものの、LEDランプは発光効率が依然好ましくない上、発光ダイオード自体が高い発熱を伴うため、熱を逃がす為の様々な機構が必要になる。   Although lighting devices using light emitting diodes as a light source have higher luminous efficiency and brightness than conventional fluorescent lamp tubes, LED lamps are still unfavorable in luminous efficiency and light emitting diodes themselves generate high heat, Various mechanisms are needed to escape.

特に、発光ダイオードを光源とする照明装置は、前述のように発光ダイオード自体が高い発熱を伴うため、蛍光ランプ管と同様な使用形態で天井に設置された取付端子装置のソケットに装着された場合、天井と照明ランプ間の隙間が僅かしか存在せず、このため十分に熱が発散せず、発光ダイオードを含め、その他の装置に熱損傷が生じてしまうことになる。また発光ダイオードは光の発散が少なく、蛍光ランプ管のように広い領域を照明するには問題がある。
そこで、特許文献1には発光効率が高く使用寿命が長い冷陰極発光体を利用した照明装置が開示されているが、照明装置のケーシングに冷陰極形電極9a、9bを組み付けるに際し、冷陰極形電極9a、9bが封着されているバルブ6の端部に金属製のキャップ10a、10bを被せ、これらキャップ10a、10bをケーシング4の樋状支持部11a、11bにかしめ固定または接着剤を使用して固定していた。
In particular, the illumination device using a light emitting diode as a light source, when the light emitting diode itself is accompanied by high heat generation as described above, is mounted on a socket of a mounting terminal device installed on the ceiling in the same usage form as a fluorescent lamp tube. There is only a small gap between the ceiling and the illumination lamp, so that heat is not sufficiently dissipated, and other devices including the light emitting diodes are thermally damaged. In addition, the light emitting diode has little light divergence, and there is a problem in illuminating a wide area like a fluorescent lamp tube.
Therefore, Patent Document 1 discloses a lighting device using a cold cathode light emitter having high luminous efficiency and a long service life. When the cold cathode electrodes 9a and 9b are assembled to a casing of the lighting device, a cold cathode type is disclosed. The end of the valve 6 to which the electrodes 9a and 9b are sealed is covered with metal caps 10a and 10b. And fixed it.

しかしながら、冷陰極形電極9a、9bが封着されているバルブ6の端部に被せられた金属製のキャップ10a、10bをケーシング4の樋状支持部11a、11bにかしめ固定するにしろ、接着剤を使用して固定するにしろ、照明装置のケーシングへの冷陰極形電極の組み付けが面倒で、照明装置の組み立てに手間がかかるという問題があった。   However, the metal caps 10a and 10b, which are placed on the ends of the bulb 6 to which the cold cathode electrodes 9a and 9b are sealed, are caulked and fixed to the saddle-like support portions 11a and 11b of the casing 4; Even if it fixes using an agent, there existed a problem that the assembly | attachment of the cold cathode type electrode to the casing of an illuminating device was troublesome, and assembly of an illuminating device took time.

本発明は、このような問題点に着目してなされたもので、発光効率が高くかつ使用寿命が長い冷陰極発光体を利用して、恰も従来の蛍光ランプ管と同様な使用形態で利用でき、広い領域を照明できる照明装置でありながら、冷陰極発光体の電極を簡単に組み付けることができる照明装置を提供することを目的とする。   The present invention has been made paying attention to such problems, and can be used in the same manner of use as a conventional fluorescent lamp tube by utilizing a cold cathode luminous body having high luminous efficiency and long service life. An object of the present invention is to provide an illuminating device capable of easily assembling an electrode of a cold cathode light emitter while being an illuminating device capable of illuminating a wide area.

前記課題を解決するために、本発明の照明装置は、内部を少なくとも上部と下部とに分離する仕切体が管軸方向に延びる中空の管本体と、前記管本体の前記仕切体の上方位置に内装されたインバータを含む制御装置と、前記管本体の前記仕切体の下方位置に管軸方向に延設された1本の平面視U字状の冷陰極発光体と、を備え、前記管本体の下部が主として光透過部材で構成されるとともに、前記仕切体の下面には前記下部の光透過部材に向けて前記冷陰極発光体の光を反射する光反射部材が設けられ、かつソケット接続用の2本の電極が貫通して配された端縁封止体が、前記管本体の両端にそれぞれ固定され前記管本体が封止されていることを特徴としている。
この特徴によれば、発光効率が高くかつ使用寿命が長い1本の平面視U字状の冷陰極発光体の光源を光反射部材を利用して反射する構造であるため、蛍光ランプ管と同様な広い領域を照明できる照明装置を提供できることになる。また管本体の仕切体の下方面が光反射部材であり、かつ前記仕切体の上方位置にインバータを含む制御装置が内装されているため、制御装置が照明部を占有することがない。すなわち光透過部材の長さと合わせて1本の平面視U字状の冷陰極発光体を管軸方向に十分延設できることになり、従来の蛍光ランプ管と同様に管本体の端部付近まで照明部として利用できることになる。また、端縁封止体には2本の電極が設けらているため、組み付けと同時に管本体が得られ照明装置の組み立てが簡単になる。
In order to solve the above-mentioned problems, the lighting device according to the present invention includes a hollow pipe body in which a partition that separates the interior into at least an upper part and a lower part extends in the pipe axis direction, and a position above the partition body of the pipe body. A control device including an inverter provided therein; and a cold cathode light emitter having a U-shape in a plan view and extending in a tube axis direction at a position below the partition of the tube body, the tube body The lower part of the partition is mainly composed of a light transmissive member, and the lower surface of the partition is provided with a light reflecting member for reflecting the light of the cold cathode light emitter toward the lower light transmissive member. An edge sealing body in which the two electrodes are inserted is fixed to both ends of the tube body, and the tube body is sealed.
According to this feature, the light source of a single U-shaped cold cathode light emitter having a high luminous efficiency and a long service life is reflected by using a light reflecting member, so that it is similar to a fluorescent lamp tube. An illumination device that can illuminate a wide area can be provided. Moreover, since the lower surface of the partition of the tube main body is a light reflecting member and a control device including an inverter is provided at an upper position of the partition, the control device does not occupy the illumination unit. That is, a single U-shaped cold cathode light emitter in plan view along with the length of the light transmitting member can be sufficiently extended in the tube axis direction, and illumination is performed up to the end of the tube main body as in the conventional fluorescent lamp tube. It can be used as a department. Further, since the edge sealing body is provided with two electrodes, the tube main body is obtained simultaneously with the assembly, and the assembly of the lighting device is simplified.

本発明の照明装置は、前記端縁封止体の少なくとも一方には前記端縁封止体の横断面形状より小さい横断面形状の頭部が設けられているとともに、該頭部から2本の電極が突出しており、灯具のソケット部に前記電極を固定できることを特徴としている。
この特徴によれば、頭部から延びる2本の電極を用いて灯具のソケット部に前記電極を固定できることは勿論、前記端縁封止体に設けられた小さい横断面形状の頭部をソケット部の押入部として利用できるため、簡単な構成で灯具のソケット部に2本の電極を固定することができる。
In the lighting device of the present invention, at least one of the edge sealing bodies is provided with a head having a cross-sectional shape smaller than the cross-sectional shape of the edge sealing body. The electrode protrudes and the electrode can be fixed to the socket portion of the lamp.
According to this feature, the electrode can be fixed to the socket portion of the lamp using two electrodes extending from the head portion, and the head portion having a small cross-sectional shape provided on the edge sealing body can be used as the socket portion. Therefore, the two electrodes can be fixed to the socket portion of the lamp with a simple configuration.

本発明の照明装置は、前記管本体の内側に延びる電極が接続されている導線が、前記仕切体の上方を通り、前記管本体の前記仕切体の上方位置に内装されたインバータを含む制御装置に接続されていることを特徴としている。
この特徴によれば、2本の電極とインバータを接続する導線が仕切体の上方を通るため、2本の電極と制御装置との接続が容易に行える。
The illuminating device of the present invention includes a control device including an inverter in which a conductive wire to which an electrode extending inside the tube main body is connected passes above the partition and is installed at an upper position of the partition of the tube main body. It is characterized by being connected to.
According to this feature, since the conducting wire connecting the two electrodes and the inverter passes above the partition, the connection between the two electrodes and the control device can be easily performed.

本発明の照明装置は、前記中空の管本体は、主として光透過部材で構成される断面略U字状の前記下部と、放熱性の高い材料で構成される前記上部との接合構造により構成され、前記上部は筒状体となっており、該筒状体の底面板が前記仕切体となっていることを特徴としている。
この特徴によれば、前記上部が筒状体となっているため、照明装置取り付け時などに生じる管本体に働く捻り力に対して、前記上部が変形を抑制し、効果的に管本体のねじり変形を防止するように働く。またインバータを含む制御装置が発生する熱は、放熱性の高い材料で構成されインバータを含む制御装置を取り囲む前記上部により効果的に放出されることになる。
In the illuminating device of the present invention, the hollow tube main body is constituted by a joint structure of the lower part having a substantially U-shaped cross section mainly composed of a light transmitting member and the upper part composed of a material having high heat dissipation. The upper part is a cylindrical body, and the bottom plate of the cylindrical body is the partition body.
According to this feature, since the upper portion is a cylindrical body, the upper portion suppresses deformation and effectively twists the tube main body against the twisting force that acts on the tube main body when the lighting device is attached. Works to prevent deformation. Further, the heat generated by the control device including the inverter is effectively released by the upper part that is made of a material having high heat dissipation and surrounds the control device including the inverter.

本発明の照明装置は、前記上部に長手方向に溝が形成されており、断面略U字状の前記下部が、前記上部の長手方向の溝に溝嵌合されて前記管本体が形成されるようになっていることを特徴としている。
この特徴によれば、照明装置のメンテナンス時など、溝方向の両者の相対移動が許容されるため、前記下部と前記上部とも分解が容易となる。特に前記下部に侵入した虫などの掃除が容易となる。
In the lighting device of the present invention, a groove is formed in the upper portion in the longitudinal direction, and the lower portion having a substantially U-shaped cross section is fitted in the groove in the longitudinal direction of the upper portion to form the tube body. It is characterized by that.
According to this feature, since the relative movement in the groove direction is allowed during maintenance of the lighting device, the lower part and the upper part can be easily disassembled. In particular, insects that have entered the lower part can be easily cleaned.

本発明の照明装置は、前記上部の溝に前記下部が溝嵌合されている前記管本体の両端が、前記上部と下部との相対移動が阻止される態様で、電極の設けられた前記端縁封止体で固定されるようになっていることを特徴としている。
この特徴によれば、前記上部の溝に前記下部が溝嵌合されているため、長手方向の相対移動を端縁封止体で固定するのみで強固な密封状の管本体を構成できるばかりか、端縁封止体には電極が設けられているため、組み付けと同時に電極を備えた管本体が得られることになる。
In the lighting device of the present invention, both ends of the tube main body in which the lower part is fitted in the upper groove are prevented from relative movement between the upper part and the lower part. It is characterized by being fixed by an edge sealing body.
According to this feature, since the lower part is fitted into the upper groove, a strong sealed tube body can be configured only by fixing the relative movement in the longitudinal direction with the edge sealing member. Since the edge sealing body is provided with the electrode, a tube body provided with the electrode is obtained simultaneously with the assembly.

本発明の照明装置は、前記管本体に形成された長手方向の溝に嵌合状態で保持される保持部と、前記冷陰極発光体を長手方向に向けて把持する把持部とからなる発光体保持片を備えていること特徴としている。
この特徴によれば、発光体保持片は、管本体内を延びる前記冷陰極発光体を支持し、移動時や大きな揺れに対して管本体内の前記冷陰極発光体を保護する働きをする。特に長手方向の溝で発光体保持片が支持されているため、長手方向にこの発光体保持片を移動設置できることから、管本体や前記冷陰極発光体の長さ条件等に応じて、前記冷陰極発光体の一番振れの激しくなるような位置を特定して揺れに対する対処が可能となる。
The illuminating device of the present invention is a light emitter comprising a holding portion that is held in a fitted state in a longitudinal groove formed in the tube main body, and a grip portion that grips the cold cathode light emitter in the longitudinal direction. It is characterized by having a holding piece.
According to this feature, the luminous body holding piece supports the cold cathode luminous body extending in the tube body, and functions to protect the cold cathode luminous body in the tube body against movement and large shaking. In particular, since the luminous body holding piece is supported by the groove in the longitudinal direction, the luminous body holding piece can be moved and installed in the longitudinal direction. Therefore, depending on the length conditions of the tube body and the cold cathode luminous body, It is possible to cope with the shaking by specifying the position where the cathode light emitter is most shaken.

本発明にかかる照明装置は、前記発光体保持片が、前記保持部と把持部とを連結する吊架部を有し、該吊架部が屈伸可能になっていることを特徴としている。
この特徴によれば、吊架部の屈曲により長手方向の溝から保持部を外し、さらに吊架部の伸長により長手方向の溝に保持部を嵌合できるようになるため、ワンタッチで発光体保持片を長手方向に容易に移動できることになる。
The illuminating device according to the present invention is characterized in that the luminous body holding piece has a suspension part that connects the holding part and the grip part, and the suspension part can be bent and stretched.
According to this feature, the holding part can be removed from the longitudinal groove by bending the suspension part, and the holding part can be fitted into the longitudinal groove by extending the suspension part. The piece can be easily moved in the longitudinal direction.

本発明に係る照明装置を実施するための形態を実施例に基づいて以下に説明する。   EMBODIMENT OF THE INVENTION The form for implementing the illuminating device which concerns on this invention is demonstrated below based on an Example.

本発明にかかる照明装置の好適な実施形態が図1以降に示されており、この照明装置3は一般の蛍光ランプ管の使用方法と同様に、二つのソケット部の間に取り付けて適用されるものであり、前記ソケット部は、既存の蛍光ランプ管の灯具に設けられているソケット部であり、照明装置3は蛍光ランプ管の代わりに利用されるランプである。照明装置3は、特に図1、図2に示されるように中空状の管本体4であり、管本体4の一端部の内部には制御装置である導電ユニット5が固定され、この導電ユニット5は主にインバータとPFC(図示せず)からなる。   A preferred embodiment of the illuminating device according to the present invention is shown in FIG. 1 and the subsequent drawings, and this illuminating device 3 is applied between two socket portions in the same manner as in a method of using a general fluorescent lamp tube. The socket part is a socket part provided in a lamp of an existing fluorescent lamp tube, and the lighting device 3 is a lamp used in place of the fluorescent lamp tube. As shown in FIGS. 1 and 2, the illumination device 3 is a hollow tube body 4, and a conductive unit 5 as a control device is fixed inside one end of the tube body 4. Consists mainly of an inverter and a PFC (not shown).

具体的には、管本体4は、断面略U字状の光透過部材9(下部)と、放熱性の高い材料で構成される筒状体10(上部)との接合構造により構成され、前記上部の筒状体10の底面板が内部を少なくとも長手方向に上下に分離する仕切体18としての機能を有している。この仕切体18の上方位置にはインバータを含む制御装置である導電ユニット5がケース体55に収納された状態で内装固定されている。このケース体55は、利用者等が容易に導電ユニット5に触れられないように遮蔽機能を有している。このように、管本体4の仕切体18の下方位置に管軸方向に延設された1本の平面視U字状の冷陰極発光体7(COld CathOde FluOrescent Lamp、略称CCFL)が設置され、前記仕切体18の下面には前記した光反射部材30が位置していることにより、光透過部材9に向けて前記冷陰極発光体7の光が反射されるようになっている。   Specifically, the tube body 4 is configured by a joining structure of a light transmitting member 9 (lower part) having a substantially U-shaped cross section and a cylindrical body 10 (upper part) made of a material having high heat dissipation, The bottom plate of the upper cylindrical body 10 has a function as a partition 18 that separates the interior at least in the longitudinal direction. The conductive unit 5, which is a control device including an inverter, is internally fixed at a position above the partition 18 while being housed in the case body 55. The case body 55 has a shielding function so that a user or the like cannot easily touch the conductive unit 5. In this way, a single U-shaped cold cathode light emitter 7 (Cold CathOde FluOrient Lamp, abbreviated as CCFL) in plan view extending in the tube axis direction is installed at a position below the partition 18 of the tube body 4. Since the light reflecting member 30 is located on the lower surface of the partition 18, the light of the cold cathode light emitter 7 is reflected toward the light transmitting member 9.

このような構造の照明装置は、発光効率が高くかつ使用寿命が長い前記冷陰極発光体7の光源を光反射部材30を利用して反射する構造であるため、蛍光ランプ管と同様な広い領域を照明できることになる。また管本体4の仕切体18の下方面が光反射部材30であり、かつ前記仕切体18の上方位置にインバータを含む制御装置である導電ユニット5が内装されているため、この導電ユニット5が照明部を占有することがない。すなわち光透過部材の長さと合わせて前記冷陰極発光体7を管軸方向に十分延設できることになり、従来の蛍光ランプ管と同様に管本体の端部付近まで照明部として利用できることになる。   The illuminating device having such a structure has a structure in which the light source of the cold cathode light emitter 7 having high luminous efficiency and long service life is reflected by using the light reflecting member 30, so that it has a wide area similar to a fluorescent lamp tube. Can be illuminated. Moreover, since the lower surface of the partition 18 of the pipe body 4 is the light reflecting member 30 and the conductive unit 5 which is a control device including an inverter is installed above the partition 18, the conductive unit 5 The lighting unit is not occupied. That is, the cold cathode light emitter 7 can be sufficiently extended in the tube axis direction along with the length of the light transmitting member, and can be used as an illumination portion up to the vicinity of the end of the tube main body as in the conventional fluorescent lamp tube.

前記管本体4の下部は、断面U字状であり、主として合成樹脂からなる半透明の光透過部材9から構成されているとともに、前記管本体4内部に管軸方向に1本の平面視U字状の冷陰極発光体7が延設され、前記冷陰極発光体7の上面には、下方に位置する前記光透過部材9に向けて前記冷陰極発光体7の光を反射する光反射部材30が設けられている。また光透過部材9は、抜き出し成型により製造される断面一定の長尺材であり、断面が略U字状であり、そのU字状の両上端部に内向きの爪部16を有する。光透過部材9はこの長尺材を所定の長さで切断して利用される。また、この光透過部材9は透明もしくは乳白色の透光性の合成樹脂が主に用いられるが、種々のカラーが適用されることもある。光透過部材9は冷陰極発光体7からの光を散乱させるために内側面は凹凸上の光散乱面に加工されている。   The lower portion of the tube body 4 has a U-shaped cross section, is composed of a translucent light transmitting member 9 mainly made of synthetic resin, and has a single plane view U in the tube axis direction inside the tube body 4. A light-reflecting member that extends in the shape of a letter and reflects the light of the cold-cathode emitter 7 toward the light-transmitting member 9 located below the upper surface of the cold-cathode emitter 7. 30 is provided. The light transmitting member 9 is a long material having a constant cross section manufactured by extraction molding, and has a substantially U-shaped cross section, and has claw portions 16 facing inward at both upper ends of the U shape. The light transmitting member 9 is used by cutting the long material into a predetermined length. The light transmitting member 9 is mainly made of a transparent or milky white light transmitting synthetic resin, but various colors may be applied. In order to scatter the light from the cold cathode light emitter 7, the inner surface of the light transmissive member 9 is processed into an uneven light scattering surface.

筒状体10を図3に基づいて更に詳しく説明すると、筒状体10は放熱性の高い材料例えばアルミ素材等で構成され、抜き出し成型により製造される断面非円形の一定の長尺材であり、筒状体10の底面板が仕切体18としての機能を有している。また6は後述する端縁封止体8の係止爪13を係止する係止溝である。このように上部が筒状体10となっているために強度が高く、照明装置取り付け時などに生じる管本体4に働く捻り力に対して、前記上部が変形を抑制し、効果的に管本体4のねじり変形を防止するように働く。また導電ユニット5が発生する熱は、放熱性の高い材料で構成された導電ユニット5を取り囲む前記上部により効果的に放出されることになる。また筒状体10の下方長手方向に走る溝14が設けられ、この溝14は光透過部材9の断面略U字状の両上端部に内向きに延びている爪部16と係合可能となっている。筒状体10の下方長手方向に走る溝14に対して、光透過部材9の爪部16を長手方向から嵌合することにより、筒状体10と光透過部材9との連結が完了する。このように溝方向においてのみ両者の相対移動が許容されるため、筒状体10と光透過部材9は上下方向に分離し辛い構造でありながら、照明装置のメンテナンス時など、両者の長手方向の相対移動で光透過部材9内にアクセスが可能となり、特に光透過部材9内に侵入した虫などの掃除が容易となる。   The cylindrical body 10 will be described in more detail with reference to FIG. 3. The cylindrical body 10 is made of a material with high heat dissipation, such as an aluminum material, and is a long material having a non-circular cross section manufactured by extraction molding. The bottom plate of the cylindrical body 10 has a function as the partition 18. Reference numeral 6 denotes a locking groove for locking a locking claw 13 of the edge sealing body 8 to be described later. Since the upper part is the cylindrical body 10 in this way, the strength is high, and the upper part suppresses deformation against the twisting force that acts on the pipe body 4 that occurs when the lighting device is attached, and the pipe body effectively. 4 to prevent torsional deformation. Also, the heat generated by the conductive unit 5 is effectively released by the upper part surrounding the conductive unit 5 made of a material with high heat dissipation. In addition, a groove 14 is provided that runs in the lower longitudinal direction of the tubular body 10, and this groove 14 can be engaged with a claw portion 16 that extends inwardly at both upper ends of the light transmitting member 9 having a substantially U-shaped cross section. It has become. By fitting the claw portion 16 of the light transmission member 9 from the longitudinal direction into the groove 14 running in the lower longitudinal direction of the cylindrical body 10, the connection between the cylindrical body 10 and the light transmission member 9 is completed. Thus, since the relative movement of both is allowed only in the groove direction, the cylindrical body 10 and the light transmitting member 9 are difficult to separate in the vertical direction, but in the longitudinal direction of the both, such as during maintenance of the lighting device. Relative movement allows access to the light transmitting member 9 and facilitates cleaning of insects and the like that have entered the light transmitting member 9 in particular.

筒状体10の両端に取り付けられる端縁封止体8について図4,5に基づいて説明すると、両側の端縁封止体8には、該端縁封止体8の横断面形状より小さい横断面形状の頭部11が設けられている。両頭部11は同一形状の円筒状凸部であって、端縁封止体8の一部となるように一体に形成されている。このように頭部11が端縁封止体に一体に形成されているため、管本体4の灯具取り付け時や使用時において、頭部11にかかる負荷に対する強度を向上できることになる。また、図11に示すように、既存の蛍光ランプ管用差し込み方式のソケット部を備えた灯具100は、通常、ソケット本体60、摺動体61、摺動体61を付勢するバネ62を備えており、前記ソケット本体60の前面には円形開口部63が形成され、摺動体61は2個の電極挿入孔64,64を備えているとともに前記開口部63に摺動可能に配設されている。頭部11はこの差し込み方式のソケット部の押入部として利用するものであるから、頭部11はこの開口部63に嵌入できる程度の大きさである。
図4,5に戻ると、端縁封止体8はこれを貫通するように2本の電極52,52が設けられ、2本の電極52,52の頭部11により外側に突出する部分は、既存の蛍光ランプ管用ソケット(図示せず)に挿入される。また、2本の電極52,52の内側に延びる部分は、集中端子19に接続され、導電ユニット5に接続されることになる。端縁封止体8の裏面側には、裏面側に延びる係止爪13が設けられており、筒状体10の側面に形成されている係止溝6に係止爪13が圧入係止されることにより、端縁封止体8がワンタッチで筒状体10の両端に取り付けられることになる。すなわち長手方向両端を端縁封止体8で固定するのみで、筒状体10と光透過部材9との溝方向の両者の相対移動を阻止し、図1に示される強固な照明装置を構成できる。また端縁封止体8には前記した2本の電極52,52が設けられているため、組み付けと同時に電極を備えた管本体が得られることになる。
さらに、端縁封止体8の下方部には、端縁封止体8を管本体4に取り付けた際に、光透過部材9の端部下方部分を外側から覆うカバー部12が延設されている。したがって、照明装置3の端部に衝撃があっても、このカバー部12により、光透過部材9の端部への直接的な衝撃が回避され、光透過部材9の破損を防止できる。
The edge sealing bodies 8 attached to both ends of the cylindrical body 10 will be described with reference to FIGS. 4 and 5. The edge sealing bodies 8 on both sides are smaller than the cross-sectional shape of the edge sealing body 8. A head 11 having a cross-sectional shape is provided. Both heads 11 are cylindrical projections having the same shape, and are integrally formed so as to be a part of the edge sealing body 8. Thus, since the head 11 is integrally formed with the edge sealing body, the strength against the load on the head 11 can be improved when the lamp body of the tube body 4 is attached or used. Further, as shown in FIG. 11, the lamp 100 including the existing fluorescent lamp tube insertion type socket portion is usually provided with a socket body 60, a sliding body 61, and a spring 62 that biases the sliding body 61. A circular opening 63 is formed on the front surface of the socket body 60, and the sliding body 61 includes two electrode insertion holes 64, 64 and is slidably disposed in the opening 63. Since the head portion 11 is used as a push-in portion of the socket portion of the insertion method, the head portion 11 has a size that can be fitted into the opening portion 63.
4 and 5, the edge sealing body 8 is provided with two electrodes 52, 52 so as to penetrate the edge sealing body 8, and the portion protruding outward by the head 11 of the two electrodes 52, 52 is And inserted into an existing fluorescent lamp tube socket (not shown). Further, the portions extending inward of the two electrodes 52, 52 are connected to the concentrated terminal 19 and connected to the conductive unit 5. On the back surface side of the edge sealing body 8, a locking claw 13 extending to the back surface side is provided, and the locking claw 13 is press-fitted into the locking groove 6 formed on the side surface of the cylindrical body 10. By doing so, the edge sealing body 8 is attached to both ends of the cylindrical body 10 with one touch. That is, only by fixing both ends in the longitudinal direction with the edge sealing body 8, the relative movement of both the cylindrical body 10 and the light transmitting member 9 in the groove direction is prevented, and the strong lighting device shown in FIG. 1 is configured. it can. Further, since the edge sealing body 8 is provided with the two electrodes 52 and 52 described above, a tube main body provided with the electrodes can be obtained simultaneously with the assembly.
Further, a cover portion 12 is provided at the lower portion of the edge sealing body 8 so as to cover the lower portion of the light transmitting member 9 from the outside when the edge sealing body 8 is attached to the tube body 4. ing. Therefore, even if there is an impact at the end portion of the illumination device 3, the cover portion 12 can avoid a direct impact on the end portion of the light transmitting member 9 and prevent the light transmitting member 9 from being damaged.

図6には、発光体保持片23が示されており、これは筒状体10に形成された長手方向の溝15に嵌合可能な保持部231と、前記冷陰極発光体7を長手方向に向けて把持する把持部232とから構成されている。また発光体保持片23は、前記保持部231と把持部232とを連結する吊架部234を有し、該吊架部234が図7に示されるように屈伸可能になっている。発光体保持片23は透明な合成樹脂製である。   FIG. 6 shows a light emitter holding piece 23, which has a holding portion 231 that can be fitted in a longitudinal groove 15 formed in the tubular body 10, and the cold cathode light emitter 7 in the longitudinal direction. It is comprised from the holding part 232 hold | gripped toward. Further, the light emitter holding piece 23 has a suspension portion 234 that connects the holding portion 231 and the grip portion 232, and the suspension portion 234 can be bent and stretched as shown in FIG. The light emitter holding piece 23 is made of a transparent synthetic resin.

この発光体保持片23は、筒状体10内を延びる前記冷陰極発光体7を図8に示されるように支持し、移動時や大きな揺れに対しても筒状体10内の冷陰極発光体7を保護する働きをする。特に長手方向の溝15で発光体保持片23が支持されているため、長手方向にこの発光体保持片23を移動設置できることから、筒状体10や前記冷陰極発光体7の長さ条件等に応じて、前記冷陰極発光体7の一番振れの激しくなるような位置を特定して揺れに対する対処が可能となる。発光体保持片23の取り付けに際しては、吊架部234の屈曲と伸長とによりワンタッチで長手方向の溝15に保持部231を嵌合できるばかりか、発光体保持片23を長手方向に容易に移動できることになる。また、吊架部234の屈曲により長手方向の溝15から保持部231を容易に外すこともできる。
また、管本体4の一端部にはインバータを含む導電ユニット5が固定されているため、そのインバータが発生する熱により前記冷陰極発光体7の両端では温度差、すなわち温度傾斜を生じることとなる。
しかしながら、発光保持片23は合成樹脂製であるため、金属製に比べて熱伝導性が低く、しかも、前記冷陰極発光体7は発光保持片23で吊架して空間に浮かした状態で保持されているため、その温度傾斜により生じる熱が直接前記冷陰極発光体7に伝わらず、前記冷陰極発光体7の耐久性が向上する。
The luminous body holding piece 23 supports the cold cathode luminous body 7 extending in the cylindrical body 10 as shown in FIG. 8, and the cold cathode light emission in the cylindrical body 10 is also generated during movement and large shaking. It works to protect the body 7. In particular, since the luminous body holding piece 23 is supported by the groove 15 in the longitudinal direction, the luminous body holding piece 23 can be moved and installed in the longitudinal direction. Therefore, the length conditions of the cylindrical body 10 and the cold cathode luminous body 7 and the like Accordingly, it is possible to identify the position at which the cold cathode luminous body 7 is most shaken and cope with the shaking. When attaching the light emitter holding piece 23, the holding portion 231 can be fitted into the groove 15 in the longitudinal direction with one touch by bending and extending the suspension portion 234, and the light emitter holding piece 23 can be easily moved in the longitudinal direction. It will be possible. Further, the holding portion 231 can be easily detached from the longitudinal groove 15 by bending the suspension portion 234.
Further, since the conductive unit 5 including an inverter is fixed to one end portion of the tube body 4, a temperature difference, that is, a temperature gradient is generated at both ends of the cold cathode light emitter 7 due to heat generated by the inverter. .
However, since the light emission holding piece 23 is made of synthetic resin, it has lower thermal conductivity than that of metal, and the cold cathode light emitter 7 is suspended by the light emission holding piece 23 and held in a floating state. Therefore, the heat generated by the temperature gradient is not directly transmitted to the cold cathode light emitter 7, and the durability of the cold cathode light emitter 7 is improved.

図9は、上記のように組み立てられた図1の照明装置のX―X断面図であり、前記冷陰極発光体7の光を反射する光反射部材30は、溝15内において発光体保持片23の保持部231により共に嵌合し、光反射部材30は筒状体10に確実に取り付けられている。したがって発光体保持片23を筒状体10から取り除くと、光反射部材30の係止が緩くなり筒状体10から光反射部材30が取り外しやすくなる。ただしこの実施例に限らず光反射部材30は筒状体10に接着剤で固定されても良いし、また筒状体10に塗布されて構成されても良い。
また、端縁封止体8を貫通する2本の電極52,52は、インバータを含む制御装置である導電ユニット5が内装された筒状の管本体4の内部に臨むように延設されているため、2本の電極52,52と導電ユニット5との接続が容易に行える。
さらには、端縁封止体8は断面非円形の筒状体10に係合爪13等により回転不可能に固定されており、また筒状体は上述した如く、管本体4のねじり変形を防止するように働くため、管本体4の灯具への取り付け時において、端縁封止体8に設けられた頭部11に掛かる負荷は、筒状体10で受け止められこととなり、頭部11の破損を防止することになる。
9 is a cross-sectional view taken along the line XX of the illumination device of FIG. 1 assembled as described above. The light reflecting member 30 that reflects the light of the cold cathode light emitter 7 has a light emitter holding piece in the groove 15. The light reflecting member 30 is securely attached to the cylindrical body 10 by being fitted together by the holding portions 231 of the 23. Therefore, when the light emitter holding piece 23 is removed from the tubular body 10, the light reflecting member 30 is loosened and the light reflecting member 30 is easily detached from the tubular body 10. However, not limited to this embodiment, the light reflecting member 30 may be fixed to the cylindrical body 10 with an adhesive, or may be applied to the cylindrical body 10.
Further, the two electrodes 52, 52 penetrating the edge sealing body 8 are extended so as to face the inside of the tubular tube body 4 in which the conductive unit 5 which is a control device including an inverter is installed. Therefore, the connection between the two electrodes 52 and 52 and the conductive unit 5 can be easily performed.
Furthermore, the edge sealing body 8 is fixed to the cylindrical body 10 having a non-circular cross section by an engaging claw 13 or the like, and the cylindrical body is subjected to torsional deformation of the tube body 4 as described above. Therefore, when the tube body 4 is attached to the lamp, the load applied to the head 11 provided on the edge sealing body 8 is received by the cylindrical body 10, and the head 11 Damage will be prevented.

そして、2本の電極52,52の内側に延びる部分は、集中端子19に接続され、導線24、25を介してそれぞれ導電ユニット5に接続されることになる。電気的に接続される前記冷陰極発光体7(CCFL)は導電ユニット5を介して導線24、25に接続され、電気的に直列接続を構成している。このため導電ユニット5内のインバータやPFCなどの機器は1個あれば十分であり、この様な簡素なかつ軽量な導電ユニット5を用いて冷陰極発光体7を配置することにより十分な照度を得ることが出来る。なお、導線24は筒状体10内に延設されることにより、導線が照明の邪魔になることがない。

The cold cathode light emitting body 7 (CCFL) to be electrically connected is connected to the conductive wires 24 and 25 through the conductive unit 5 to form an electrical series connection. For this reason, one device such as an inverter or PFC in the conductive unit 5 is sufficient, and sufficient cold intensity is obtained by arranging the cold cathode light emitter 7 using such a simple and lightweight conductive unit 5. I can do it. In addition, since the conducting wire 24 extends in the cylindrical body 10, the conducting wire does not interfere with illumination.

インバータは図示されていないが、2本の電極52,52から得られる電圧を例えば20〜100KHz、200〜3000Vに昇圧し、この高周波出力が電気的に接続された前記冷陰極発光体7に印加される。インバータには高周波出力のデューティサイクルを可変する調光制御回路を付加することが好ましい。調光制御はデューティサイクルを可変する方式に限定されない。インバータは、本実施形態においては一般の自励発振型インバータであるが、実用に際してこれに限定されない。   Although the inverter is not shown, the voltage obtained from the two electrodes 52 and 52 is boosted to, for example, 20 to 100 KHz and 200 to 3000 V, and this high frequency output is applied to the cold cathode light emitter 7 to which it is electrically connected. Is done. It is preferable to add a dimming control circuit for changing the duty cycle of the high frequency output to the inverter.
