Description

本発明は、蛍光ランプと点灯装置とを備えた蛍光ランプ装置及び照明器具に関する。   The present invention relates to a fluorescent lamp device and a lighting fixture including a fluorescent lamp and a lighting device.

従来、屈曲されたバルブを備えた発光管を有する蛍光ランプと、この発光管を点灯させる点灯装置とを一体的に備えた蛍光ランプ装置が用いられている(例えば、特許文献１参照。)。このような蛍光ランプ装置について、平面的な光源を得るため、扁平な円盤状の本体に点灯装置を収容し、この本体の上面に一体的に口金部を設けるとともに、本体の下面に沿って平面状に屈曲された発光管を配置し、さらに、これら本体の下面と発光管とをグローブで覆った扁平な円盤状の蛍光ランプ装置が知られている(例えば、非特許文献１参照。)。
特開平６−２８３１３９号公報 シルバニア 0025219 マイクロリンクス F 7W/840(SYLVANIA 0025219 Micro-Lynx F 7W/840)、[online]、2005年、シルバニア ライティング インターナショナル(Sylvania Lighting International)、[平成18年3月28日検索]、インターネット＜http://www.sylvania-lamps.com/catalog/pdflib/lamps2pdf.php?id=2514＞ 2. Description of the Related Art Conventionally, a fluorescent lamp device that is integrally provided with a fluorescent lamp having an arc tube having a bent bulb and a lighting device that lights the arc tube has been used (see, for example, Patent Document 1). For such a fluorescent lamp device, in order to obtain a planar light source, the lighting device is accommodated in a flat disk-shaped main body, and a base portion is provided integrally on the upper surface of the main body, and the flat surface along the lower surface of the main body There has been known a flat disk-shaped fluorescent lamp device in which arc tubes bent in a shape are arranged and the lower surface of the main body and the arc tube are covered with a globe (see, for example, Non-Patent Document 1).
JP-A-6-283139 Sylvania 0025219 Microlinks F 7W / 840 (SYLVANIA 0025219 Micro-Lynx F 7W / 840), [online], 2005, Sylvania Lighting International, [March 28, 2006 search], Internet <http : //www.sylvania-lamps.com/catalog/pdflib/lamps2pdf.php? id = 2514>

しかしながら、発光管と点灯装置とを重ねて配置する構成では、互いに近接して配置された発光管及び点灯装置の発熱により、各部の温度が上昇し、例えば、非特許文献１に記載された構成では、本体の温度は、最高で９５度まで上昇する旨が示されている(Housing temperature 95℃ maximum)。すなわち、発光管の消費電力が大きくなると発光管の温度が所望の範囲を超えて上昇し、発光効率が低下するという問題を有している。また、発光管の温度上昇により、点灯装置の回路の上限規格温度を満足させることが困難になる。さらに、発光管や点灯装置の温度上昇に伴い、本体の温度が上昇すると、この本体が対向する取付面の温度が上昇し、取付面の変色や劣化の進行の原因となる。一方、発光管の最冷部温度を低下させ、あるいは、点灯装置の回路の上限規格温度を満足させるために、発光管や点灯装置を収納する部分の容積を大きくすると、蛍光ランプ装置が大形化する問題を有している。   However, in the configuration in which the arc tube and the lighting device are arranged so as to overlap each other, the temperature of each part rises due to the heat generated by the arc tube and the lighting device arranged close to each other. For example, the configuration described in Non-Patent Document 1 Shows that the temperature of the main body rises up to 95 degrees (Housing temperature 95 ° C. maximum). In other words, when the power consumption of the arc tube increases, the temperature of the arc tube rises beyond a desired range, and the luminous efficiency decreases. Moreover, it becomes difficult to satisfy the upper limit standard temperature of the circuit of the lighting device due to the temperature rise of the arc tube. Furthermore, when the temperature of the main body rises as the temperature of the arc tube and the lighting device rises, the temperature of the mounting surface facing the main body increases, causing discoloration and deterioration of the mounting surface. On the other hand, in order to reduce the coldest part temperature of the arc tube, or to satisfy the upper limit standard temperature of the circuit of the lighting device, if the volume of the portion that accommodates the arc tube or the lighting device is increased, the fluorescent lamp device becomes large. Have the problem of becoming

本発明は、このような点に鑑みなされたもので、蛍光ランプを用いて小形かつ薄形の平面的な光源を実現できるとともに、点灯中の発光管温度を低下させ、発光効率を向上できる蛍光ランプ装置及び照明器具を提供することを目的とする。   The present invention has been made in view of these points, and can realize a small and thin planar light source by using a fluorescent lamp, and can reduce the temperature of the arc tube during lighting and improve the luminous efficiency. It aims at providing a lamp device and a lighting fixture.

本発明の蛍光ランプ装置は、発光管と、発光管を一面側で支持する平板部および平板部の外周縁側に設けられた縁部と平板部の他面側に設けられた上面部とで構成された略環状の鍔状部を有し、この鍔状部が外方に露出するように形成されている金属製の仕切体と、この仕切体の鍔状部の他面側内方に配設されて鍔状部よりも他面側に突出する収容部を有し、この収容部と鍔状部との間であって他面側に突設する口金ピンが設けられたカバー部材と、発光管の点灯回路を有し、カバー部材の収容部内に配設された点灯装置と、開口端部が仕切体の平板部の一面側に支持された透光性のグローブとを具備していることを特徴とする。   The fluorescent lamp device according to the present invention includes an arc tube, a flat plate portion that supports the arc tube on one surface side, an edge portion provided on the outer peripheral side of the flat plate portion, and an upper surface portion provided on the other surface side of the flat plate portion. And a metal partition formed so that the hook-shaped portion is exposed to the outside, and an inner side of the other surface side of the hook-shaped portion of the partition. A cover member provided with a cap pin that protrudes on the other surface side between the storage portion and the hook-shaped portion, and has a storage portion that protrudes to the other surface side than the hook-shaped portion; A lighting device having a lighting circuit for the arc tube, and a lighting device disposed in the housing portion of the cover member, and a translucent glove whose opening end portion is supported on one surface side of the flat plate portion of the partition. It is characterized by that.

本発明において、発光管は、一本の発光管を略Ｕ字形に屈曲したもの、複数本の直管形のガラス管端部を相互に接合し略Ｈ字形に連結したもの、螺旋状に巻いたもの、さらには放電路が平面状に蛇行された平面形状のもの等、その形状は種々の形態が許容され、特定の形態のものには特に限定されない。さらに、上記のように構成された発光管は、単独で使用されても、また上記の発光管が複数用意され、これら複数の発光管が連続して連通するように連結して使用されるようにしてもよい。   In the present invention, the arc tube is formed by bending one arc tube into a substantially U shape, joining a plurality of straight tube end portions to each other and connecting them in a substantially H shape, or spirally winding the arc tube. Various shapes are allowed, such as a flat shape having a discharge path meandering in a flat shape, and the shape is not particularly limited to a specific shape. Further, the arc tube configured as described above may be used alone, or a plurality of the above-described arc tubes may be prepared, and the plurality of arc tubes may be connected and used continuously. It may be.

金属製の仕切体の材質は熱伝導性が良好なものであれば特に制約されないが、アルミニウム、銅もしくはアルミニウムまたは銅を含む合金等、熱伝導率が高く、安価でかつ軽量な金属であることが好ましい。   The material of the metal partition is not particularly limited as long as it has good thermal conductivity, but it is a metal that has high thermal conductivity, is inexpensive and lightweight, such as aluminum, copper or aluminum or an alloy containing copper. Is preferred.

さらに、仕切体の金属は、白色または光沢があり、光の反射率が高い表面を有していることが好ましいが、特にこれらの要素を有することには限定はされない。   Furthermore, the metal of the partition is preferably white or glossy and preferably has a surface with high light reflectivity, but is not particularly limited to having these elements.

仕切体の平板部の形状は円盤状の他、四角形、八角形、六角形等の多角形状をなしていてもよい。   The shape of the flat plate portion of the partition may be a disc shape or a polygonal shape such as a quadrangle, an octagon, or a hexagon.

仕切体の平板部に発光管を支持する構成は特に限定されない。例えば、シリコーン接着剤などの熱伝導性のよい接着剤によって熱的な接続が行われていると効果的である。   The configuration for supporting the arc tube on the flat plate portion of the partition is not particularly limited. For example, it is effective that the thermal connection is performed by an adhesive having good thermal conductivity such as a silicone adhesive.

仕切体の鍔状部は、平板部の外周縁側に設けられた縁部と平板部の他面側に設けられた上面部とで構成されており、縁部が外周方向の外方に、上面部が他面側方向の外方にそれぞれ露出するように平板部の周縁形状に沿った略環状に形成されている。この鍔状部によって外方に露出する面積が大きくなり、放熱効果が良好となる。しかし、商品の外観上の問題からあまり大きくするには限界があるので、鍔状部の露出面積や段部の形状は、放熱効果と外観、意匠上の観点等から設計上の問題として適宜選択すればよい。   The saddle-shaped portion of the partition is composed of an edge portion provided on the outer peripheral edge side of the flat plate portion and an upper surface portion provided on the other surface side of the flat plate portion. It is formed in a substantially annular shape along the peripheral shape of the flat plate portion so that the portion is exposed outward in the direction of the other surface. The area exposed to the outside is increased by the hook-shaped portion, and the heat dissipation effect is improved. However, since there is a limit to making it too large due to problems in the appearance of the product, the exposed area of the bowl-shaped part and the shape of the stepped part are appropriately selected as a design problem from the viewpoint of heat dissipation effect, appearance, design, etc. do it.

また鍔状部は、平板部の全周縁にわたり連続した環形状をなすように設けることが好ましいが、必ずしも全周縁にわたる連続した環形状をなしている必要はなく、放熱性能が確保できていれば平板部の全周縁方向の一部が欠けた形状でもよい。   Moreover, it is preferable to provide the bowl-shaped part so as to form a continuous ring shape over the entire periphery of the flat plate part, but it is not always necessary to form a continuous ring shape over the entire periphery, and if heat dissipation performance can be secured. The shape in which a part of the entire peripheral direction of the flat plate portion is missing may be used.

そして、本発明の蛍光ランプ装置は、仕切体の鍔状部が平板部の外周方向および他面側方向にそれぞれ露出するように形成されているので鍔状部の外方に露出する面積が大きくなり、発光管から放出される熱が平板部を介して鍔状部に伝熱されて良好に放熱される。これにより、蛍光ランプ装置が大形化することなく、発光管の温度が所望の範囲内に抑えられて発光効率の低下が抑制されるとともに、点灯装置の回路の上限規格温度を満足させることが可能となる。さらに、カバー本体の温度上昇も抑制されるので、カバー本体に対向する取付面の変色や劣化が起こり難くなる。   The fluorescent lamp device according to the present invention is formed so that the bowl-shaped portion of the partition body is exposed in the outer peripheral direction and the other surface side direction of the flat plate portion, respectively, so that the area exposed to the outside of the bowl-shaped portion is large. Thus, the heat released from the arc tube is transferred to the bowl-shaped portion through the flat plate portion and is radiated well. As a result, the fluorescent lamp device is not increased in size, and the temperature of the arc tube can be suppressed within a desired range to prevent a decrease in luminous efficiency, and the upper-limit standard temperature of the circuit of the lighting device can be satisfied. It becomes possible. Furthermore, since the temperature rise of the cover body is also suppressed, discoloration or deterioration of the mounting surface facing the cover body is difficult to occur.

本発明の蛍光ランプ装置の他の形態は、仕切体の平板部と鍔状部とが一体成形されていることを特徴としている。   Another embodiment of the fluorescent lamp device of the present invention is characterized in that the flat plate portion and the bowl-shaped portion of the partition are integrally formed.

鍔状部が発光管を支持する平板部と一体に形成されていると、平板部から鍔状部に良好に熱伝導されるため、発光管の熱を効果的に放熱することが可能となる。仕切体は、例えば、アルミニウム等のダイキャストでも、アルミニウム板をプレス加工したものなどでもよく、一体に形成する具体的な手段、方法等は特には限定されない。   When the bowl-shaped part is formed integrally with the flat plate part that supports the arc tube, heat conduction from the flat plate part to the bowl-shaped part is good, so that the heat of the arc tube can be effectively radiated. . The partition may be, for example, die cast of aluminum or the like, or may be a product obtained by press-working an aluminum plate, and the specific means, method, and the like that are integrally formed are not particularly limited.

本発明の照明器具は、器具本体と、この器具本体に取付けられた上記蛍光ランプ装置とを具備していることを特徴としている。   The lighting fixture of the present invention is characterized by including a fixture main body and the fluorescent lamp device attached to the fixture main body.

そして、この構成では、上記蛍光ランプ装置を備えているので、小形かつ薄形の平面的な光源が実現されるとともに、所望の温度領域が形成され、発光効率が容易に向上する。また、点灯装置を内蔵した蛍光ランプ装置がソケット装置に着脱され、取り扱いが容易になる。   And in this structure, since the said fluorescent lamp apparatus is provided, while a small and thin planar light source is implement | achieved, a desired temperature range is formed and luminous efficiency improves easily. In addition, the fluorescent lamp device incorporating the lighting device is attached to and detached from the socket device, and the handling becomes easy.

本発明の蛍光ランプ装置によれば、仕切体の鍔状部が平板部の外周方向および他面側方向にそれぞれ露出するように形成されているので、鍔状部の外方に露出する面積が大きくなり、発光管から放出される熱が鍔状部から効果的に放熱され、発光管の発光効率の低下が抑制されるとともに、点灯装置の回路の上限規格温度を満足させることが可能となる。   According to the fluorescent lamp device of the present invention, the hook-shaped portion of the partition is formed so as to be exposed in the outer peripheral direction and the other surface side direction of the flat plate portion, respectively, so that the area exposed to the outside of the hook-shaped portion is It becomes large and the heat emitted from the arc tube is effectively radiated from the bowl-shaped portion, the decrease in luminous efficiency of the arc tube is suppressed, and the upper limit temperature of the circuit of the lighting device can be satisfied. .

The edge portion 32c and the upper surface portion 32d are integrally formed together with the flat plate portion 32b, and a substantially annular flange portion 32a is formed by the edge portion 32c and the upper surface portion 32d. Then, the edge portion 32c of the flange portion 32a is exposed outward in the outer peripheral direction of the flat plate portion 32b, and the upper surface portion 32d is exposed outward in the other surface direction of the flat plate portion 32b. In addition, although the partition body 32 is formed by die-casting, such as aluminum, for example, the thing which press-processed the aluminum plate may be sufficient and the specific means, method, etc. which form integrally are not specifically limited.

カバー部材３１は、樹脂によって成形されており、仕切体３２の鍔状部３２ａの内方に図示しない嵌合手段によって嵌合固着されている。カバー部材３１の中央部には、鍔状部３２ａの上面部３２ｄよりも他面側に突出する収容部３１ａが形成されており、この収容部３１内側に形成されている収容空間には発光管３３の点灯回路を有する点灯装置３８が収容されている。点灯装置３８の点灯回路は、回路基板３８ａに実装された電解コンデンサやトランジスタからなるスイッチ素子等の回路部品３８ｂによって構成されたインバータ回路からなる。カバー部材３１の収容部３１ａと鍔状部３２ａとの間には、他面側に突出する一対の口金ピン３５，３５が突設されている。一対の口金ピン３５，３５の基端部と回路基板３８ａとは、リード線３８ｃ，３８ｃによって電気的に接続されている。   The cover member 31 is formed of resin, and is fitted and fixed to the inner side of the bowl-shaped portion 32a of the partition 32 by a fitting means (not shown). A housing portion 31a is formed at the center of the cover member 31 so as to protrude from the upper surface portion 32d of the bowl-shaped portion 32a to the other surface side. The housing space formed inside the housing portion 31 has an arc tube. A lighting device 38 having 33 lighting circuits is accommodated. The lighting circuit of the lighting device 38 is composed of an inverter circuit constituted by circuit components 38b such as an electrolytic capacitor and a switch element made of a transistor mounted on a circuit board 38a. A pair of cap pins 35, 35 protruding from the other surface side is provided between the housing portion 31 a and the bowl-shaped portion 32 a of the cover member 31. The base ends of the pair of cap pins 35, 35 and the circuit board 38a are electrically connected by lead wires 38c, 38c.

発光管３３の内面には、図示しない蛍光体層が設けられ、内部にアルゴン(Ar)、ネオン(Ne)、あるいはクリプトン(Kr)などの希ガスや水銀などを含む封入ガスが封入されている。発光管３３は、３本のＵ字状に屈曲されたバルブを連通管で順次接続し、１本の連続した放電路を形成している。３本のＵ字状バルブのうち、両側のバルブの各一端部には、ステムシールまたはピンチシールによって電極が封装されている。発光管３３のＵ字状バルブは、シリコーン樹脂を主成分とする接着剤３９で仕切体３２の平板部３２ｂに沿って取り付けられる。   A phosphor layer (not shown) is provided on the inner surface of the arc tube 33, and a sealed gas containing a rare gas such as argon (Ar), neon (Ne), or krypton (Kr) or mercury is sealed therein. . In the arc tube 33, three U-shaped bulbs are sequentially connected by a communication tube to form one continuous discharge path. Of the three U-shaped valves, electrodes are sealed by stem seals or pinch seals at respective one end portions of the valves on both sides. The U-shaped bulb of the arc tube 33 is attached along the flat plate portion 32b of the partition 32 with an adhesive 39 mainly composed of silicone resin.

グローブ３４は、透光性を有し、すなわち、透明あるいは光拡散性を有するガラスや合成樹脂により、上側（他面側）に開口部を設けた扁平な曲面形状に形成されている。そして、この開口部を囲む縁部は、上側に向かう取付部となるとともに、この取付部が鍔状部３２ａの下側（一面側）に取付けられている。   The globe 34 has translucency, that is, is formed in a flat curved surface shape having an opening on the upper side (the other surface side) of transparent or light diffusing glass or synthetic resin. And the edge part surrounding this opening part becomes an attaching part toward the upper side, and this attaching part is attached to the lower side (one surface side) of the hook-shaped part 32a.

次に、本実施形態の作用について説明する。蛍光ランプ装置３０は、仕切体３２の鍔状部３２ａのうち縁部３２ｃが平板部３２ｂの外周方向に、および上面部３２ｄが平板部３２ｂの他面側方向にそれぞれ露出しているので、鍔状部３２ａの外方に露出する面積が大きくなり、発光管３３から放出される熱が平板部３２ｂを介して鍔状部３２ａに良好に伝熱されて放熱される。これにより、蛍光ランプ装置３０が大形化することなく、発光管３３の温度が所望の範囲内に抑えて発光効率が低下することを抑制でき、点灯装置３８の回路部品３８ｂの上限規格温度を満足させることが可能となる。さらに、カバー本体３１の温度上昇も抑制されるので、カバー本体３１に対向する天井面Ｘの変色や劣化が起こり難くなる。   Next, the operation of this embodiment will be described. In the fluorescent lamp device 30, the edge portion 32 c is exposed in the outer peripheral direction of the flat plate portion 32 b and the upper surface portion 32 d is exposed in the other surface side direction of the flat plate portion 32 b. The area exposed to the outside of the shaped portion 32a is increased, and the heat released from the arc tube 33 is well transferred to the bowl-shaped portion 32a through the flat plate portion 32b and radiated. Thus, the fluorescent lamp device 30 is not increased in size, and the temperature of the arc tube 33 can be suppressed within a desired range and the luminous efficiency can be prevented from being lowered, and the upper limit standard temperature of the circuit component 38b of the lighting device 38 can be reduced. It becomes possible to satisfy. Furthermore, since the temperature rise of the cover main body 31 is also suppressed, discoloration and deterioration of the ceiling surface X facing the cover main body 31 are unlikely to occur.

また、鍔状部３２ａが平板部３２ｂと一体に形成されているので、平板部３２ｂから鍔状部３２ａへの熱伝導が効率よく行われ、発光管３３の熱を効果的に放熱することが可能となる。   Further, since the hook-shaped portion 32a is formed integrally with the flat plate portion 32b, heat conduction from the flat plate portion 32b to the hook-shaped portion 32a is performed efficiently, and the heat of the arc tube 33 can be effectively radiated. It becomes possible.

次に、第２の実施形態の蛍光ランプ装置を説明する。図３は第２の実施形態の蛍光ランプ装置の側断面図である。なお、本実施形態において、第１の実施形態と同一の構成については同一符号を付し、その詳細な説明は省略する。   Next, a fluorescent lamp device according to a second embodiment will be described. FIG. 3 is a side sectional view of the fluorescent lamp device according to the second embodiment. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

本実施形態では、仕切体３２の平板部３２ｂと発光管３３との間に高反射率を有するように表面が研磨処理された反射面が一面側に形成されたアルミニウム製の反射板４０が配設されている。   In the present embodiment, an aluminum reflecting plate 40 having a reflecting surface whose surface is polished so as to have a high reflectivity between the flat plate portion 32b of the partition 32 and the arc tube 33 is disposed on one side. It is installed.

この反射板４０を配設することで、発光管３３の出力光の反射効率が向上し、蛍光ランプ装置３０のランプ効率を改善することができる。また、発光管３３の放射熱も反射されることから、仕切体３２に伝導される熱量が抑えられ、仕切体３２およびカバー部材３１の温度上昇を抑えることが可能となる。なお、仕切体３２の平板部３２ｂとカバー部材３１の収容空間３１ａとの間に空気層やガラスウール層などからなる図示しない断熱層を設けて、収容空間３１ａ内の温度上昇を抑制し、点灯装置３８の熱劣化を防止することも可能である。   By disposing the reflection plate 40, the reflection efficiency of the output light from the arc tube 33 is improved, and the lamp efficiency of the fluorescent lamp device 30 can be improved. Further, since the radiant heat of the arc tube 33 is also reflected, the amount of heat conducted to the partition 32 is suppressed, and the temperature rise of the partition 32 and the cover member 31 can be suppressed. In addition, a heat insulating layer (not shown) made of an air layer, a glass wool layer, or the like is provided between the flat plate portion 32b of the partition body 32 and the housing space 31a of the cover member 31 to suppress the temperature rise in the housing space 31a and light up. It is also possible to prevent thermal degradation of the device 38.

次に、第３の実施形態の蛍光ランプ装置を説明する。図４は第３の実施形態の蛍光ランプ装置の側断面図である。なお、本実施形態において、第１の実施形態と同一の構成については同一符号を付し、その詳細な説明は省略する。   Next, a fluorescent lamp device according to a third embodiment will be described. FIG. 4 is a side sectional view of the fluorescent lamp device according to the third embodiment. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

本実施形態では、鍔状部３２ａの上面部３２ｄの高さ位置が第１の実施形態よりも平板部３２ｂの一面側に近くなっていて、この上面部３２ｄの内側縁部からの口金ピン３５の突出面高さまで立上るように形成された周壁部３２ｅが鍔状部３２ａと一体的に設けられている。このように、鍔状部３２ａの上面部３２ｄを平板部３２ｂの一面側に近づけて周壁部３２ｅを形成することによって、鍔状部３２ａの外方に露出する表面積を確保しながら、鍔状部３２ａの上面部３２ｄをソケット装置３６の下面から離すことができるので、上面部３２ｄの放熱効果を高めることが可能となる。   In the present embodiment, the height position of the upper surface portion 32d of the bowl-shaped portion 32a is closer to the one surface side of the flat plate portion 32b than in the first embodiment, and the cap pin 35 from the inner edge of the upper surface portion 32d. A peripheral wall portion 32e formed so as to rise up to the height of the protruding surface is integrally provided with the flange portion 32a. In this way, by forming the peripheral wall portion 32e by bringing the upper surface portion 32d of the hook-shaped portion 32a closer to one surface side of the flat plate portion 32b, the hook-shaped portion is secured while ensuring the surface area exposed to the outside of the hook-shaped portion 32a. Since the upper surface portion 32d of 32a can be separated from the lower surface of the socket device 36, the heat dissipation effect of the upper surface portion 32d can be enhanced.

本発明の第１の実施の形態の蛍光ランプ装置の(a)は側面図、(b)は上面図をそれぞれ示す。FIG. 2A is a side view and FIG. 2B is a top view of the fluorescent lamp device according to the first embodiment of the present invention. 図１の蛍光ランプ装置の側断面図。FIG. 2 is a side sectional view of the fluorescent lamp device of FIG. 1. 本発明の第２の実施の形態の蛍光ランプ装置の側断面図。The sectional side view of the fluorescent lamp apparatus of the 2nd Embodiment of this invention. 本発明の第３の実施の形態の蛍光ランプ装置の側断面図。The sectional side view of the fluorescent lamp device of the 3rd Embodiment of this invention.
