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.

従来の照明器具として、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、多くの照明器具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。   In general, fluorescent lamp tubes that emit light mainly by gas discharge have been widely used as conventional lighting fixtures. However, with the widespread use of power-saving light-emitting diodes (Light Emitting Diodes, abbreviated as LEDs), more and more lighting is used. Light emitting diodes are being adopted as light sources in appliances.

図１２に示すように、一般の発光ダイオードを光源とする照明ランプ１０１は管本体１１０と、管本体１１０の両端部にそれぞれ取り付けられている二つの導電ユニット１２０と、管本体１１０の中に設けられて導電ユニット１２０の間に電気的に接続されている発光ユニット１３０とを備えている。発光ユニット１３０は、回路基板１３１と、回路基板１３１に電気的に接続された複数の発光ダイオード１３２とを備えている。このような照明ランプ１０１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１３２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。そのため、発光ダイオードを利用するには依然として多くの制限がある。   As shown in FIG. 12, an illumination lamp 101 using a general light emitting diode as a light source is provided in a tube body 110, two conductive units 120 attached to both ends of the tube body 110, and the tube body 110. And a light emitting unit 130 that is electrically connected between the conductive units 120. The light emitting unit 130 includes a circuit board 131 and a plurality of light emitting diodes 132 electrically connected to the circuit board 131. Although such an illumination lamp 101 has higher luminous efficiency and brightness than the conventional fluorescent lamp tube, the LED lamp is still unfavorable in luminous efficiency, and the light emitting diode 132 itself generates high heat, so that heat can be released. Various mechanisms are required. As a result, there are still many limitations to using light emitting diodes.

特に、発光ダイオードを光源とする照明ランプ１０１は、前述のように発光ダイオード１３２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１０１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１３２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１３２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。   In particular, the illumination lamp 101 using a light emitting diode as a light source is attached to a socket of a mounting terminal device installed on the ceiling in the same manner of use as a fluorescent lamp tube because the light emitting diode 132 itself generates high heat as described above. In this case, there is only a small gap between the ceiling and the illumination lamp 101, so that heat is not sufficiently dissipated, and other devices including the light emitting diode 132 are thermally damaged. The light emitting diode 132 has little light divergence, and there is a problem in illuminating a wide area such as a fluorescent lamp tube.

本発明は、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を提供することを目的とする。   An object of the present invention is to provide a lighting device that can illuminate a wide area by using a cold cathode luminous body having high luminous efficiency and a long service life, and can be used in the same usage pattern as a conventional fluorescent lamp tube. And

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、前記管本体の内部に管軸方向に複数の冷陰極発光体が延設され、前記複数の冷陰極発光体の上面には下方に位置する前記光透過部材に向けて冷陰極発光体の光を反射する光反射部材が設けら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になっているため、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。 The lighting device according to the present invention is
The lower portion of the tube main body is mainly composed of a light transmitting member, and a plurality of cold cathode light emitters extend in the tube axis direction inside the tube main body, and are positioned below the upper surfaces of the plurality of cold cathode light emitters.

According to this feature, the light source of the cold cathode illuminant having high luminous efficiency and long service life is reflected by using the light reflecting member, so that illumination that can illuminate a wide area similar to a fluorescent lamp tube is possible. A device can be provided.

この特徴によれば、発光効率が高くかつ使用寿命が長い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。 The lighting device according to the present invention is
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, a control device including an inverter built in an upper position of the partition body of the pipe body, and the pipe body A plurality of cold cathode light emitters extending in a tube axis direction at a lower position of the partition, the lower portion of the tube body is mainly composed of a light transmitting member, and the lower portion of the partition A light reflecting member that reflects the light of the cold cathode light emitter toward the light transmitting member is provided.
According to this feature, the light source of the cold cathode illuminant having high luminous efficiency and long service life is reflected by using the light reflecting member, so that the illumination device capable of illuminating a wide area similar to the fluorescent lamp tube is provided. It 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, the cold cathode light emitter can be sufficiently extended in the tube axis direction in accordance 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.

本発明の上述の、及びその他の技術内容、特徴と効果は、添付図面に基づく好適な実施形態に関する以下の詳細な説明により、明らかになるであろう。   The above-described and other technical contents, features, and advantages of the present invention will become apparent from the following detailed description of preferred embodiments based on the accompanying drawings.

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（図示せず）の間に取り付けて適用されるものであり、前記ソケットは、既存の蛍光灯の基体に設けられているソケットであり、照明装置３は蛍光灯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 subsequent figures, and this illuminating device 3 is mounted between two sockets (not shown) in the same manner as a general fluorescent lamp tube. The socket is a socket provided on the base of an existing fluorescent lamp, 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複数の冷陰極発光体７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 with 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 plurality of cold cathode light emitters 7 extending in the tube axis direction are installed at positions below the partition body 18 of the tube body 4, and the light reflecting member 30 is positioned on the lower surface of the partition body 18. As a result, 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 a high luminous efficiency and a long service life is reflected by using the light reflecting member 30, and thus has a wide area similar to a fluorescent lamp tube. It will be able to illuminate. 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内部に管軸方向に複数の冷陰極発光体７が延設され、前記複数の冷陰極発光体７の上面には、下方に位置する前記光透過部材９向けて冷陰極発光体７の光を反射する光反射部材３０が設けられている。電気的に接続される複数の冷陰極発光体７（Ｃｏｌｄ Ｃａｔｈｏｄｅ Ｆｌｕｏｒｅｓｃｅｎｔ Ｌａｍｐ、略称ＣＣＦＬ）は２本用いられているが、本数に関しては要求される明るさに応じて、適宜本数は選択できる。ここで２本の冷陰極発光体７、７は接続線１５で接続されているが、これは後述するように冷陰極発光体が直列接続される構造を採るために必要な構成である。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１４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 main body 4 has a U-shaped cross section, is composed of a semitransparent light transmitting member 9 mainly made of synthetic resin, and a plurality of cold cathode light emitters in the tube axis direction inside the tube main body 4. 7 is extended, and a light reflecting member 30 for reflecting the light of the cold cathode light emitter 7 toward the light transmitting member 9 located below is provided on the upper surface of the plurality of cold cathode light emitters 7. Two cold cathode light emitting bodies 7 (Cold Cathode Fluorescent Lamp, abbreviated as CCFL) that are electrically connected are used, but the number can be selected as appropriate according to the required brightness. Here, the two cold cathode light emitters 7 and 7 are connected by a connection line 15, which is a configuration necessary for adopting a structure in which the cold cathode light emitters are connected in series as will be described later. The light transmissive 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 inward claw portions 14 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１２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１３が設けられ、この溝１３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１４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１３に対して、光透過部材９の爪部１４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。１７はピン孔である。   The cylindrical body 10 will be described in more detail with reference to FIG. 3. The cylindrical body 10 is made of a material having high heat dissipation, such as an aluminum material, and is a long material with a constant cross section manufactured by extraction molding. The bottom plate of the body 10 has a function as the partition 18. Reference numeral 6 denotes a locking groove for locking a locking claw 12 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. Further, a groove 13 that runs in the lower longitudinal direction of the cylindrical body 10 is provided, and this groove 13 can be engaged with a claw portion 14 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 14 of the light transmitting member 9 into the groove 13 running in the lower longitudinal direction of the tubular body 10 from the longitudinal direction, the connection between the tubular body 10 and the light transmitting 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 transmission member 9 are difficult to separate in the vertical direction, but in the maintenance of the lighting device, both in the longitudinal direction. 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. Reference numeral 17 denotes a pin hole.

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、端縁封止体８はこれを貫通するように電極５２が設けられ、電極５２の外側に延びる部分は、図示しないソケットに挿入される電極部であり、２本の電極５２の内側に延びる部分は、集中端子１６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１２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１２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には前記した電極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。   The edge sealing body 8 attached to both ends of the cylindrical body 10 will be described with reference to FIGS. 4 and 5. The edge sealing body 8 is provided with electrodes 52 so as to penetrate the edge sealing body 8, The extending portion is an electrode portion inserted into a socket (not shown), and the portion extending inside the two electrodes 52 is connected to the concentrated terminal 16 and connected to the conductive unit 5. On the back surface side of the edge sealing body 8, a locking claw 12 extending to the back surface side is provided, and the locking claw 12 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. Since the edge sealing body 8 is provided with the electrode 52 described above, a tube main body provided with the electrode is obtained simultaneously with the assembly.

さらに端縁封止体８は、電極５２が設けられた上部封止体８２と下部封止体８３とを区画するようにその境界に比較的肉薄の折曲部８１が形成されているとともに、図５に示されるように上部封止体８２と下部封止体８３の内面部には、それぞれ貫通部２０を有する係合片２１が設けられている。１９は、前記した係合片２１の貫通部２０に上方から貫通係止可能な係止ピンであり、係止ピン１９の頂部はＴ状に形成されている。矢印で示される方向に、係止ピン１９を上部封止体８２と下部封止体８３におけるそれぞれの係合片２１の貫通部２０に同時に嵌入することにより、折曲部８１の位置で曲がりにくい端縁封止体８が構成できる。   Further, the edge sealing body 8 has a relatively thin bent portion 81 formed at the boundary so as to partition the upper sealing body 82 and the lower sealing body 83 provided with the electrode 52, As shown in FIG. 5, engagement pieces 21 each having a penetrating portion 20 are provided on the inner surfaces of the upper sealing body 82 and the lower sealing body 83. Reference numeral 19 denotes a locking pin that can be penetrated and locked to the penetrating portion 20 of the engaging piece 21 from above, and the top of the locking pin 19 is formed in a T shape. It is difficult to bend at the position of the bent portion 81 by simultaneously fitting the locking pin 19 into the through portions 20 of the engaging pieces 21 in the upper sealing body 82 and the lower sealing body 83 in the direction indicated by the arrow. The edge sealing body 8 can be configured.

図６には照明装置のメンテナンス時などにおける態様が示されており、前記端縁封止体８の一部の変形もしくは移動、すなわちこの実施例によれば、矢印で示される方向に、係止ピン１９を少なくとも下部封止体８３における係合片２１の貫通部２０から抜くことにより、折曲部８１の位置での端縁封止体８の曲げが許容される。その結果、矢印に示されるように、筒状体１０と光透過部材９との溝方向においてのみの両者の相対移動が許容され、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。また、変形や移動を伴わない端縁封止体８における上部封止体８２に電極５２が設けられているため、照明装置のメンテナンス時などにおいて、電極５２及びそこに繋がるインバータを含む制御装置である導電ユニット５が露出することがなく、安全性が保たれる。   FIG. 6 shows an aspect during maintenance of the lighting device, etc., and a part of the edge sealing body 8 is deformed or moved, that is, according to this embodiment, it is locked in the direction indicated by the arrow. By bending the pin 19 from at least the penetrating portion 20 of the engagement piece 21 in the lower sealing body 83, bending of the edge sealing body 8 at the position of the bent portion 81 is allowed. As a result, as indicated by the arrows, relative movement between the cylindrical body 10 and the light transmission member 9 only in the groove direction is allowed, and access within the light transmission member 9 is achieved by the relative movement of both in the longitudinal direction. In particular, it is easy to clean insects that have entered the light transmitting member 9. In addition, since the electrode 52 is provided on the upper sealing body 82 in the edge sealing body 8 that is not deformed or moved, a control device including the electrode 52 and an inverter connected to the electrode 52 is used during maintenance of the lighting device. A certain conductive unit 5 is not exposed, and safety is maintained.

図７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１３に嵌合可能な保持部２３１と、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８に示されるように屈伸可能になっている。   FIG. 7 shows a light emitter holding piece 23, which includes a holding portion 231 that can be fitted in a longitudinal groove 13 formed in the cylindrical body 10, and a 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.

この発光体保持片２３は、筒状体１０内を延びる冷陰極発光体７を図９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１３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や冷陰極発光体７の長さ条件等に応じて、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１３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１３から保持部２３１を容易に外すこともできる。   The luminous body holding piece 23 supports the cold cathode luminous body 7 extending in the cylindrical body 10 as shown in FIG. 9, and the cold cathode luminous body in the cylindrical body 10 during movement and large shaking. It works to protect 7. In particular, since the luminous body holding piece 23 is supported by the groove 13 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 are met. Accordingly, it is possible to identify the position where the cold cathode luminous body 7 is most shaken and cope with the shaking. When attaching the luminous body holding piece 23, the holding section 231 can be fitted into the longitudinal groove 13 with one touch by bending and extending the suspension section 234, and the luminous body holding piece 23 can be easily moved in the longitudinal direction. It will be possible. Further, the holding portion 231 can be easily removed from the groove 13 in the longitudinal direction by bending the suspension portion 234.

図１０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、冷陰極発光体７の光を反射する光反射部材３０は、溝１３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。   FIG. 10 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 is disposed in the groove 13 with the light emitter holding piece 23. The light reflecting member 30 is securely attached to the cylindrical body 10 by being fitted together by the holding portion 231. 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.

照明装置３内部に装備されるランプ設備は図１１に詳しく開示されており、端縁封止体８はこれを貫通するように電極５２が設けられ、電極５２の外側に延びる部分は、図示しないソケットに挿入される電極部であり、２本の電極５２の内側に延びる部分は、集中端子１６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複数の冷陰極発光体７（ＣＣＦＬ）は２本用いられており、２本の冷陰極発光体７、７の一端は接続線１５で接続され、これら冷陰極発光体７、７の他端は導電ユニット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を用いて複数本の冷陰極発光体７を並列に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 lamp equipment provided inside the lighting device 3 is disclosed in detail in FIG. 11, and the edge sealing body 8 is provided with an electrode 52 so as to penetrate the edge sealing body 8, and a portion extending outside the electrode 52 is not shown. The electrode part inserted into the socket and extending inward of the two electrodes 52 is connected to the concentrated terminal 16 and connected to the conductive unit 5 via the conductive wires 24 and 25, respectively. Two cold cathode light emitters 7 (CCFL) to be electrically connected are used, and one end of each of the two cold cathode light emitters 7 and 7 is connected by a connection line 15. , 7 are connected to the conductive wires 24, 25 via the conductive unit 5 to form an electrical series connection. For this reason, only one device such as an inverter or PFC in the conductive unit 5 is sufficient, and by arranging a plurality of cold cathode light emitters 7 in parallel using such a simple and lightweight conductive unit 5. Sufficient illuminance can be obtained. 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、電極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各冷陰極発光体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 electrode 52 is boosted to, for example, 20 to 100 KHz and 200 to 3000 V, and this high frequency output is applied to each cold cathode light emitter 7 electrically connected. It is preferable to add a dimming control circuit for changing the duty cycle of the high frequency output to the inverter. The dimming control is not limited to a method of changing the duty cycle. The inverter is a general self-oscillation type inverter in this embodiment, but is not limited to this in practical use.

以上の内容は、本発明の好適な実施形態の一例に過ぎず、本発明の実施の範囲を限定するものではない。すなわち、本発明の特許請求の範囲及び明細書に記載の内容に基づく簡単な、同等の変更や修正は、全て特許請求の範囲に包含される。   The above content is only an example of a preferred embodiment of the present invention, and does not limit the scope of implementation of the present invention.
