Description

本発明は、蛍光ランプやＬＥＤ等のランプと点灯装置とを備えたランプ装置及び照明器具に関する。   The present invention relates to a lamp device and a lighting fixture including a lamp such as a fluorescent lamp or an LED 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。)。   Conventionally, a fluorescent lamp device integrally including a fluorescent lamp having an arc tube with a bent bulb and a lighting device for lighting the arc tube has been used (see, for example, Patent Document 1).

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17年11月10日検索]、インターネット＜http://www.sylvania-lamps.com/catalog/pdflib/lamps2pdf.php?id=2514＞ 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 is formed 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, [Search November 10, 2005], Internet <http : //www.sylvania-lamps.com/catalog/pdflib/lamps2pdf.php? id = 2514>

さらに、ホルダ１３の下側からグローブ１７を被せ、側壁部１７ｂの上端部分を取付受部１３ｇに挿入してシリコーン樹脂などの耐熱性の接着剤で接着する。  Further, the globe 17 is covered from the lower side of the holder 13, and the upper end portion of the side wall portion 17b is inserted into the attachment receiving portion 13g and bonded with a heat-resistant adhesive such as silicone resin.

このようにして、例えば、外径寸法は７５mm、高さ寸法は３２．９mm、口金部２３はＧＸ５３形式、蛍光ランプ１１の定格出力は８Ｗである安定器を内蔵した平面状の蛍光ランプ装置１０が構成される。   In this way, for example, a flat fluorescent lamp device 10 with a built-in ballast having an outer diameter dimension of 75 mm, a height dimension of 32.9 mm, a base portion 23 of GX53 format, and a rated output of the fluorescent lamp 11 of 8 W. Is configured.

上記に構成された蛍光ランプ装置１０は、天井面Ｘに取り付けられたソケット装置２０に装着されて照明器具１を構成する。  The fluorescent lamp device 10 configured as described above is mounted on the socket device 20 attached to the ceiling surface X to constitute the lighting fixture 1.

図４に示すように、ソケット装置２０は、円筒状をなすケース体２０ａを備え、このケース体がねじなどにて天井面Ｘに固定されている。また、このケース体２０ａには、ソケット部を構成する図示しない一対の接続金具が収容され、これら接続金具にそれぞれ天井部に配線された商用交流電源のＦケーブルの芯線が電気的に接続されている。   As shown in FIG. 4, the socket device 20 includes a case body 20a having a cylindrical shape, and the case body is fixed to the ceiling surface X with screws or the like. The case body 20a accommodates a pair of connection fittings (not shown) constituting the socket portion, and core wires of commercial AC power supply F cables wired to the ceiling portion are electrically connected to the connection fittings. Yes.

さらに、ケース体２０ａの下面には、各接続金具に沿って、ソケット部を構成する給電孔２０ｂが形成されている。各給電孔は、ケース体の中心に対して回転対称に位置し、長孔状の溝部の一端に円孔状の拡径部２０ｃが設けられている。  Furthermore, the power supply hole 20b which comprises a socket part is formed in the lower surface of the case body 20a along each connection metal fitting.

Has been.

上記に構成されたソケット装置２０に蛍光ランプ装置１０が装着される。  The fluorescent lamp device 10 is mounted on the socket device 20 configured as described above.

すなわち、ソケット装置２０の本体収容部２０ｄに、口金体１５の内筒部１５ｂ、すなわち天板部を下側から位置合わせして挿入し、さらに、口金部１５の口金ピン１５ｇのプラグ部１５ｉを各給電孔２０ｂの拡径部２０ｃに挿入して、蛍光ランプ装置１０を所定方向（図４中右回り）に回動させる。  That is, the inner tube portion 15b of the base body 15, that is, the top plate portion is aligned and inserted into the main body housing portion 20d of the socket device 20 from the lower side, and the plug portion 15i of the base pin 15g of the base portion 15 is further inserted. The fluorescent lamp device 10 is inserted into the enlarged diameter portion 20c of each power supply hole 20b, and is rotated in a predetermined direction (clockwise in FIG. 4).

これにより、各口金ピン１５ｇのプラグ部１５ｉが、ソケット装置２０の接続金具に電気的及び機械的に接続されるとともに、口金体１５の係合保持受部がソケット装置の係合保持部２０ｅに係合し、機械的に保持される。  Thereby, the plug portion 15i of each base pin 15g is electrically and mechanically connected to the connection fitting of the socket device 20, and the engagement holding receiving portion of the base body 15 is connected to the engagement holding portion 20e of the socket device. Engage and hold mechanically.

また、上記取付時の動作と反対方向に蛍光ランプ装置１０を回動させることにより、蛍光ランプ装置はソケット装置から容易に取り外すことができる。  Further, the fluorescent lamp device 10 can be easily detached from the socket device by rotating the fluorescent lamp device 10 in the direction opposite to the operation at the time of attachment.

次に上記に構成された照明器具の作動につき説明する。上記のように蛍光ランプ装置１０をソケット装置２０に装着すると、蛍光ランプ装置に商用交流電源が供給され、内蔵した点灯装置１６のインバータ回路により蛍光ランプ１１の発光管１１ａが高周波で点灯される。  Next, the operation of the above-configured lighting fixture will be described. When the fluorescent lamp device 10 is mounted on the socket device 20 as described above, commercial AC power is supplied to the fluorescent lamp device, and the arc tube 11a of the fluorescent lamp 11 is turned on at high frequency by the inverter circuit of the built-in lighting device 16.

蛍光ランプが点灯すると、発光管１１ａの温度が上昇し、発生した熱は、ホルダ１３のランプ取付面１３ｃから口金体１５に収納された点灯装置１６側に伝達される。  When the fluorescent lamp is turned on, the temperature of the arc tube 11a rises, and the generated heat is transmitted from the lamp mounting surface 13c of the holder 13 to the lighting device 16 housed in the base body 15.

しかし、ホルダ１３は、エッジ部１３ｅが本体外部に露出するように構成され放熱フィンとして機能をなし、常に外気により冷却されており、ホルダに伝達された熱は順次外部に放出される。  However, the holder 13 is configured such that the edge portion 13e is exposed to the outside of the main body, functions as a heat radiating fin, and is always cooled by the outside air, and the heat transmitted to the holder is sequentially released to the outside.

同時に、ホルダ１３の内周部分Ｙも、口金体１５の外周とホルダ１３の外周との間に形成された隙間Ｓにより外部と連通され、対流作用により常に外気が流通して熱交換され、ホルダの内面からも外部に放熱される。この際、隙間Ｓにより仕切板１４の外面も外気に接し同時に冷却される。すなわち、ホルダ１３全体の放熱面積が大きくなるので、放熱効果が向上する。  At the same time, the inner peripheral portion Y of the holder 13 is also communicated with the outside through a gap S formed between the outer periphery of the base body 15 and the outer periphery of the holder 13, and the outside air is always circulated and heat-exchanged by the convection action. The heat is also radiated from the inner surface to the outside. At this time, the outer surface of the partition plate 14 also comes into contact with the outside air by the gap S and is cooled at the same time. That is, since the heat radiation area of the entire holder 13 is increased, the heat radiation effect is improved.

これらの作用により、発光管１１ａで発生した熱は効果的に外部に放熱され、点灯装置１６の回路部品側にはあまり伝達されずに温度上昇が抑制される。  By these actions, the heat generated in the arc tube 11a is effectively radiated to the outside, and the temperature rise is suppressed without being transmitted to the circuit component side of the lighting device 16 so much.

これにより、点灯装置１６の電気部品１６ｂが発光管１１ａの直上に配置されて点灯装置と発光管とが構造上近接し、電気部品の温度が高くなりやすい、平面的な蛍光ランプ装置においても、ホルダ１３を放熱構造として兼用し、かつ空気流通手段である隙間Ｓを形成することにより、発光管１１ａから伝わる熱を効率良く外部に放熱し、点灯装置１６の部品温度を低下させ、点灯装置１６の寿命が短くなることが抑制される。  Thereby, in the flat fluorescent lamp device in which the electrical component 16b of the lighting device 16 is disposed immediately above the arc tube 11a, the lighting device and the arc tube are close in structure, and the temperature of the electrical component is likely to be high. By using the holder 13 also as a heat dissipation structure and forming a gap S that is an air circulation means, the heat transmitted from the arc tube 11a is efficiently radiated to the outside, the component temperature of the lighting device 16 is lowered, and the lighting device 16 It is suppressed that the lifetime of the is shortened.

また、蛍光ランプ１１の出力を大きくした場合にも、効率良く放熱して点灯装置１６の部品温度を十分に低下させることができ、点灯装置を収容する口金体１５の全体を金属で形成するよりも、点灯装置の部品温度を十分に低下できる。その結果、口金体１５を安価な樹脂で構成することが可能となり、加工性を良好にして製造コストを低減できる。  Further, even when the output of the fluorescent lamp 11 is increased, heat can be efficiently radiated to sufficiently reduce the component temperature of the lighting device 16, and the entire base body 15 that houses the lighting device is made of metal. However, the component temperature of the lighting device can be sufficiently reduced. As a result, the base body 15 can be made of an inexpensive resin, so that the workability can be improved and the manufacturing cost can be reduced.

以上、本実施例によれば、点灯装置１６に重ねて蛍光ランプ１１の発光管１１ａの各バルブ１１ｂ、１１ｃ、１１ｄを並列に配置したため、小形かつ薄型の平面的な光源を実現できる。   As described above, according to the present embodiment, since the bulbs 11b, 11c, and 11d of the arc tube 11a of the fluorescent lamp 11 are arranged in parallel on the lighting device 16, a small and thin planar light source can be realized.

また、蛍光ランプ１１の発光管１１ａは、本体１２とグローブ１７との間の狭い空間に配置され、さらに、点灯装置１６に近接してランプ取付面１３ｃに沿って配置されているため、温度が上昇しやすくなる。  Further, the arc tube 11a of the fluorescent lamp 11 is disposed in a narrow space between the main body 12 and the globe 17, and further disposed along the lamp mounting surface 13c in the vicinity of the lighting device 16, so that the temperature is high. It becomes easy to rise.

しかし、ホルダ１３は熱伝導性の良好な材料であるアルミニウムで形成され、さらに、蛍光ランプ１１の発光管１１ａを接着して保持するカバー基板部１３ａに一体に形成されたカバー縁部１３ｂのエッジ部１３ｅが本体外部に露出するように構成され放熱フィンとして機能をなし、常に外気により冷却され熱を外部に放出する。同時に、ホルダの内周部分Ｙも、口金体１５の外周とホルダ１３の外周との間に形成された隙間Ｓにより外部と連通され、対流作用により常に外気が流通して熱交換され、ホルダの内面からも外部に放熱される。  However, the holder 13 is made of aluminum, which is a material having good thermal conductivity, and the edge of the cover edge portion 13b formed integrally with the cover substrate portion 13a for adhering and holding the arc tube 11a of the fluorescent lamp 11 The portion 13e is configured to be exposed to the outside of the main body and functions as a heat radiating fin, and is always cooled by the outside air and releases heat to the outside. At the same time, the inner peripheral portion Y of the holder is also communicated with the outside through a gap S formed between the outer periphery of the base body 15 and the outer periphery of the holder 13, and the outside air is always circulated by the convection action and heat exchange is performed. Heat is radiated from the inside to the outside.

これにより、発光管で発生した熱は効果的に外部に放熱され、蛍光ランプ装置１０全体の温度を低下させ、同時に点灯装置の電気部品側にはあまり伝達されずに温度上昇が抑制され、点灯装置１６の上限規格温度を容易に満足させることができ、電気部品の信頼性を向上させることができる。  As a result, the heat generated in the arc tube is effectively dissipated to the outside, lowering the temperature of the entire fluorescent lamp device 10, and at the same time, the temperature rise is suppressed without being transmitted to the electrical components side of the lighting device. The upper limit standard temperature of the device 16 can be easily satisfied, and the reliability of the electrical components can be improved.

また、蛍光ランプ１１と点灯装置１６との間に、熱伝導性の低い合成樹脂からなる仕切板１４を配置したため、蛍光ランプの熱による点灯装置への熱的影響を、さらに抑制することができ、点灯装置１６の上限規格温度をさらに容易に満足させ、より一層の信頼性向上を図ることができる。  Moreover, since the partition plate 14 made of a synthetic resin having low thermal conductivity is disposed between the fluorescent lamp 11 and the lighting device 16, the thermal influence on the lighting device due to the heat of the fluorescent lamp can be further suppressed. Further, the upper limit standard temperature of the lighting device 16 can be more easily satisfied, and the reliability can be further improved.

ホルダ１３のカバー縁部１３ｂのエッジ部１３ｅ外周面は、傾斜面としたため表面積が向上し、放熱性をより一層向上させることができる。  Since the outer peripheral surface of the edge portion 13e of the cover edge portion 13b of the holder 13 is an inclined surface, the surface area is improved and the heat dissipation can be further improved.

蛍光ランプ１１の発光管１１ａとホルダ１３とをシリコーン樹脂製のランプ接着手段３０で接着したため、蛍光ランプ１１の熱を効率良くホルダ１３に伝えることができる。   Since the arc tube 11a of the fluorescent lamp 11 and the holder 13 are bonded by the lamp bonding means 30 made of silicone resin, the heat of the fluorescent lamp 11 can be efficiently transmitted to the holder 13.

このように、点灯装置１６に実装されている各種電気部品の上限規格温度を容易に満足し、本体１２の温度を低下させるなど、熱的な問題を解決できるため、高出力の蛍光ランプ装置を構成することも容易になる。  As described above, the high-temperature fluorescent lamp device can be obtained because the upper standard temperature of various electrical components mounted on the lighting device 16 can be easily satisfied and the thermal problem such as the temperature of the main body 12 can be reduced. It is also easy to configure.

高出力の光を得るために蛍光ランプ１１を大きくした場合には、図５の説明図に示すように、発光管１１ａの電極リードワイヤが存する導電部１１ｈが、ますますホルダ１３の外周部側に形成されることになる。その結果、導電部１１ｈを合成樹脂からなる口金体１５で覆う必要が生じ、ホルダ１３の外部への露出部分がますます少なくなり放熱効果が低下する問題がある。   When the fluorescent lamp 11 is enlarged in order to obtain high output light, as shown in the explanatory diagram of FIG. 5, the conductive portion 11h where the electrode lead wire of the arc tube 11a is present is increasingly on the outer peripheral side of the holder 13. Will be formed. As a result, it is necessary to cover the conductive portion 11h with the base body 15 made of synthetic resin, and there is a problem that the exposed portion of the holder 13 to the outside is further reduced and the heat dissipation effect is lowered.

しかし、口金体１５の外周とホルダ１３の外周との間に隙間Ｓによる空気流通手段を設けることにより、効果的な放熱が可能となり高出力化への対応が十分可能となる。  However, by providing an air circulation means by the gap S between the outer periphery of the base body 15 and the outer periphery of the holder 13, it is possible to effectively dissipate heat and sufficiently cope with high output.

蛍光ランプ１１に近接して配置されるホルダ１３は、導電性を有する金属製であるため、蛍光ランプに対して近接導体として機能し、蛍光ランプの始動特性も向上させることが可能となる。  Since the holder 13 disposed in the vicinity of the fluorescent lamp 11 is made of a conductive metal, it functions as a proximity conductor for the fluorescent lamp, and the starting characteristics of the fluorescent lamp can be improved.

本体１２の口金体１５などの温度を容易に低下させることができるため、蛍光ランプ装置を天井面Ｘなどに設置した場合、設置面に対する熱による変色などの影響を抑制できる。  Since the temperature of the cap body 15 of the main body 12 can be easily lowered, when the fluorescent lamp device is installed on the ceiling surface X or the like, the influence of discoloration due to heat on the installation surface can be suppressed.

本体１２は、ホルダ１３と口金体１５とで外郭が構成されるいわゆる２ピースであり、構造を簡略化できるとともに組み立て作業を簡略化でき、製造コストを低減できる。   The main body 12 is a so-called two-piece whose outer shape is constituted by the holder 13 and the base body 15, can simplify the structure, simplify the assembling work, and reduce the manufacturing cost.

以上、本実施例では、空気流通手段である隙間Ｓを、口金体１５の外周とホルダ１３の外周との間に連続して環状に形成したが、図６（ａ）に示すように、口金体１５の外周とホルダ１３の外周の少なくとも一方から隙間を形成するために、所定の間隔を有して設けられたスペーサ用の複数個の突起４０を形成してもよい。この構成によれば隙間を確実に形成することができる。  As described above, in this embodiment, the gap S, which is an air circulation means, is continuously formed in an annular shape between the outer periphery of the base body 15 and the outer periphery of the holder 13, but as shown in FIG. In order to form a gap from at least one of the outer periphery of the body 15 and the outer periphery of the holder 13, a plurality of spacer projections 40 provided with a predetermined interval may be formed. According to this configuration, the gap can be reliably formed.

また、図６（ｂ）に示すように、小径の口金体１５で構成する場合には、口金体１５の外周部とホルダ１３の非露出部である内周面との間に隙間Ｓを形成するようにしてもよい。  In addition, as shown in FIG. 6B, when the small-diameter base body 15 is used, a gap S is formed between the outer peripheral portion of the base body 15 and the inner peripheral surface that is a non-exposed portion of the holder 13. You may make it do.

図６（ｂ）に示す小径の口金体１５で構成する場合には、口金体の口金体基板部１５ａの外周部が全周にわたりエッジ部１３ｅから離間し、カバー基板部１３ａの外周部部分に広い空間部４２が形成され、より効果的に放熱が行われる。   In the case of the small-diameter base body 15 shown in FIG. 6B, the outer peripheral portion of the base body substrate portion 15a of the base body is separated from the edge portion 13e over the entire circumference, and is formed on the outer peripheral portion of the cover substrate portion 13a. A wide space 42 is formed, and heat is radiated more effectively.

また、図６（ｃ）に示すように、ホルダ１３の非露出部である内周面Ｙを外部に連通させる放熱用の孔４３を、ホルダの露出部であるエッジ部１３ｅに多数形成してもよい。  Further, as shown in FIG. 6 (c), a large number of heat radiation holes 43 for communicating the inner peripheral surface Y which is a non-exposed portion of the holder 13 to the outside are formed in the edge portion 13e which is the exposed portion of the holder. Also good.

さらに、外部に連通する通気口を口金体１５などに設けることにより、点灯装置１６及び口金体１５などの温度を低減するようにしてもよい。これによれば蛍光ランプ装置１０の内部の圧力の上昇を一層抑制できる。  Furthermore, the temperature of the lighting device 16 and the base body 15 may be reduced by providing a vent hole communicating with the outside in the base body 15 or the like. According to this, the rise in the pressure inside the fluorescent lamp device 10 can be further suppressed.

また、発光管１１ａを保持するホルダ１３を熱伝導率１７０Ｗ／ｍ・Ｋのアルミニウムで構成したが、８Ｗ／ｍ・Ｋ以上を有している樹脂で構成してもよい。  Moreover, although the holder 13 holding the arc tube 11a is made of aluminum having a thermal conductivity of 170 W / m · K, it may be made of a resin having 8 W / m · K or more.

さらに、ホルダ１３の材料は、熱伝導率１０Ｗ／ｍ・Ｋ以上の材料を使用するのが好ましい。例えば、銅（Ｃｕ）、鉄（Ｆｅ)、ニッケル（Ｎｉ）の少なくとも１種を含む金属あるいはセラミック等、さらには高熱伝導樹脂等の合成樹脂でホルダ１３を構成することにより、温度を低減する効果を確保できる。  Furthermore, the material of the holder 13 is preferably a material having a thermal conductivity of 10 W / m · K or more. For example, the temperature can be reduced by configuring the holder 13 with a metal or ceramic containing at least one of copper (Cu), iron (Fe), nickel (Ni), or a synthetic resin such as a high thermal conductive resin. Can be secured.

さらに、ホルダ１３のエッジ部１３ｅ外周面に放熱性を向上する処理を施し、各部の温度低下を図ることができる。例えば、アルミニウム製のホルダ１３の全面に白色のメラニンフェノールを塗布することにより、ホルダ１３のカバー縁部１３ｂの外周面では、輻射を効率良く行い各部の温度低下を図ることができるとともに、グローブ１７に覆われたランプ取付面１３ｃなどの部分については、反射率を向上して効率良く照明できる。   Furthermore, the heat treatment can be performed on the outer peripheral surface of the edge portion 13e of the holder 13 to reduce the temperature of each portion. For example, by applying white melanin phenol to the entire surface of the aluminum holder 13, radiation can be efficiently performed on the outer peripheral surface of the cover edge portion 13 b of the holder 13, and the temperature of each portion can be lowered. The portions such as the lamp mounting surface 13c covered with the light can be efficiently illuminated with improved reflectivity.

断熱手段である仕切板１４は、ガラスウールや発泡ウレタン等の断熱性材料で構成することにより、点灯装置１６及び口金体１５などの温度を低減する効果を確保できる。   The partition plate 14 which is a heat insulating means can be made of a heat insulating material such as glass wool or foamed urethane, thereby ensuring the effect of reducing the temperature of the lighting device 16 and the base body 15.

蛍光ランプ１１の発光管１１ａなどの形状は、３本のＵ字状のバルブ１１ｂ、１１ｃ、１１ｄを連通管１１ｅで順次接続した、所謂３Ｕの構成にしたが、４Ｕ、６Ｕ等でも、さらには渦巻き形状など種々の形状を採ることができる。  The shape of the fluorescent tube 11 such as the arc tube 11a is a so-called 3U configuration in which three U-shaped bulbs 11b, 11c, and 11d are sequentially connected by a communication tube 11e, but 4U, 6U, etc. Various shapes such as a spiral shape can be adopted.

本実施例では、天井面Ｘの下面に直付け設置される照明器具１について説明したが、この構成に限らず、天井面に形成された円孔に埋込設置されるソケット装置を用い、ダウンライト式の照明器具を構成することもできる。また、天井面への取り付けに限らず、壁面取り付け、あるいはソケット装置を天井面から吊り下げることもできる。  In the present embodiment, the lighting fixture 1 installed directly on the lower surface of the ceiling surface X has been described. However, the present invention is not limited to this configuration, and a socket device embedded in a circular hole formed on the ceiling surface is used to A light-type lighting fixture can also be configured. Moreover, not only the attachment to a ceiling surface but wall surface attachment or a socket apparatus can also be suspended from a ceiling surface.

以上、本発明の好適な実施形態を説明したが、本発明は上述の実施例に限定されることなく、本発明の要旨を逸脱しない範囲内において、種々の設計変更を行うことができる。  Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the scope of the present invention.
