Description

本発明は、照明ユニットに関し、特に、製造時、輸送時、保管時、取付け時等に取扱いの容易な照明ユニットに関する。   The present invention relates to a lighting unit, and more particularly to a lighting unit that is easy to handle during manufacture, transportation, storage, installation, and the like.

近年、発光ダイオードや有機ＥＬ（Organic Electro-Luminescence）を用いた固体照明は小型で高効率である等、優れた特性を有しているので、既存の蛍光灯に代わるものとして普及が望まれている。
固体照明により蛍光灯を代替するに当たって、現状、世界中に膨大な数の蛍光灯用のインフラが整備されており、これらを固体照明の専用器具に置き換えようとすると大変なコストがかかってしまう。 In recent years, solid-state lighting using light-emitting diodes and organic EL (Organic Electro-Luminescence) has excellent characteristics such as small size and high efficiency. Therefore, it is desired to spread as an alternative to existing fluorescent lamps. Yes.
When replacing fluorescent lamps with solid-state lighting, a huge number of fluorescent lamp infrastructures have been established all over the world, and it would be very costly to replace these with dedicated fixtures for solid-state lighting.

このため、例えば、蛍光灯用のインフラに適用することができるＬＥＤランプ（Light-Emitting Diode Lamp）が提案されている（特許文献１、２を参照）。すなわち、従来の蛍光灯とまったく同じ外径寸法や口金を有し、ガラス管内にＬＥＤを封入したランプである。   For this reason, for example, LED lamps (Light-Emitting Diode Lamps) that can be applied to infrastructure for fluorescent lamps have been proposed (see Patent Documents 1 and 2). That is, the lamp has exactly the same outer diameter and base as a conventional fluorescent lamp, and the LED is enclosed in a glass tube.

特開２００８−２８２７９３号公報JP 2008-282793 A 特開２００８−１３５３５９号公報JP 2008-135359 A

しかしながら、上記従来技術に係るＬＥＤランプは、蛍光灯の代替という目的から、蛍光灯の長所のみならず短所までも引き継いでいる。すなわち、蛍光灯は長尺のガラス製品であるために、製造時や輸送時、保管時、取付時など、すべての場面において取扱いに注意を要するという不便があり、代替用のＬＥＤランプもまたこの短所を有している。
また、代替用ＬＥＤランプは、直管や丸管など様々な形状の蛍光灯に合わせて個別に設計しなければ、既存の蛍光灯用インフラに適用することができない。 However, the LED lamp according to the above prior art has inherited not only the advantages but also the disadvantages of the fluorescent lamp for the purpose of replacing the fluorescent lamp. In other words, since fluorescent lamps are long glass products, there is an inconvenience that handling is required in all situations, such as during manufacturing, transportation, storage, and installation. Has disadvantages.
Further, the replacement LED lamp cannot be applied to the existing infrastructure for fluorescent lamps unless it is individually designed for various types of fluorescent lamps such as straight tubes and round tubes.

本発明は、上述のような問題に鑑みて為されたものであって、小型・軽量化により取扱い容易で、既存の多様な蛍光灯用器具に適合する照明ユニットを提供することを目的とする。   The present invention has been made in view of the above-described problems, and an object thereof is to provide an illumination unit that is easy to handle by being reduced in size and weight and that is suitable for various existing fluorescent lamp fixtures. .

上記目的を達成するため、本発明に係る照明ユニットは、既存の蛍光灯に代替する照明ユニットであって、蛍光灯用口金端子を備える給電端子部と、代替する蛍光灯の管長より短い柱状をし、内部に固体発光素子を有する少なくとも１の発光部と、すべての発光部が電気的に連結され、その最外端の発光部と前記給電端子部とを連結し、かつ給電端子部から各発光部の固体発光素子への給電路を構成する、可撓性の配電体と、を備え、前記発光部はその柱状外壁の一部に、蛍光灯用器具に発光部を座着させる着座部材が設けられると共に、他の一部に所望の配光に調整する配光調整部材が設けられていることを特徴とする。   In order to achieve the above object, an illumination unit according to the present invention is an illumination unit that replaces an existing fluorescent lamp, and has a feeding terminal portion that includes a base terminal for a fluorescent lamp, and a column shape shorter than the tube length of the alternative fluorescent lamp. And at least one light emitting unit having a solid state light emitting element inside and all the light emitting units are electrically connected, the outermost light emitting unit and the power supply terminal unit are connected, and each of the power supply terminal units A flexible power distribution body that constitutes a power feeding path to the solid state light emitting device of the light emitting unit, and the light emitting unit is seated on a part of the columnar outer wall to seat the light emitting unit on the fluorescent lamp device And a light distribution adjusting member for adjusting to a desired light distribution is provided in another part.

このようにすれば、可撓性の配電体部分で照明ユニットを折り畳むことができるので、従来蛍光灯代替ＬＥＤランプのように長尺にならず、輸送や保管、店頭での陳列等、容易に取り扱うことができる。また、発光部が代替する蛍光灯の管長よりも短いので、代替する蛍光灯と同じ管長を有する従来ランプよりも器具への取付け、取り外しも容易になり、安全性も高まる。   In this way, the lighting unit can be folded at the flexible power distribution part, so it is not as long as conventional fluorescent lamp replacement LED lamps, and can be easily transported, stored, displayed at stores, etc. It can be handled. In addition, since the light emitting unit is shorter than the tube length of the fluorescent lamp to be replaced, it is easier to attach to and remove from the fixture than the conventional lamp having the same tube length as the fluorescent lamp to be replaced, and the safety is also improved.

また、接続する発光部の個数を変えることによって、異なる大きさの蛍光灯用器具に適用することができるので、部材を共通化することが可能となり、蛍光灯用器具ごとに長さの異なるガラス管を用意しなければならない従来ランプよりもコストを低減することができる。
また、可撓性の配電体で外力による衝撃を吸収することができるので、従来ランプよりも破損を免れ易い一方、着座部材にて蛍光灯用器具に座着されるので、使用時に揺動することなく安定した配光を実現することができる。 In addition, by changing the number of light-emitting parts to be connected, it can be applied to fluorescent lamp fixtures of different sizes, so that it is possible to share members, and glass with different lengths for each fluorescent lamp fixture. The cost can be reduced as compared with a conventional lamp in which a tube must be prepared.
In addition, since the impact due to external force can be absorbed by the flexible power distribution body, it is easier to avoid the damage than the conventional lamp, while the seat member is seated on the fluorescent lamp device, so that it swings during use. Stable light distribution can be realized without any problem.

なお、前記着座部材は、磁石、粘着部及び面ファスナのうちの少なくとも１つの取り付け手段を備え、当該取り付け手段にて蛍光灯用器具に取り付けられるのが好ましい。
また、発光部どうしを連結する配電体を備えれば外力による衝撃を更に緩和することができる。
また、発光部が、他の発光部と密接した状態で、当該他の発光部と電気的に接続するための電極を備え、発光部どうしは前記電極にて密接して連結されれば、発光部どうしが密接して連結されるので、優れた配光を実現することができる。 In addition, it is preferable that the said seating member is provided with at least 1 attachment means among a magnet, an adhesion part, and a hook-and-loop fastener, and is attached to the fixture for fluorescent lamps by the said attachment means.
Further, if a power distribution body for connecting the light emitting portions is provided, the impact due to external force can be further alleviated.
In addition, the light emitting unit includes an electrode for electrically connecting to the other light emitting unit in a state of being in close contact with the other light emitting unit, and the light emitting unit emits light when the light emitting units are closely connected to each other with the electrode. Since the parts are closely connected, an excellent light distribution can be realized.

また、給電端子部や発光部から配電体が脱着可能とすれば、照明ユニットを折り畳むことができるだけでなく、分解して更にコンパクトに梱包することができるので、輸送時の取り扱いが容易である。
また、配光調整部材が着座部材から脱着可能とすれば、照明ユニットが使用される環境に応じて、適切な配光調整部材を装着することによって、優れた配光特性を実現することができる。また、発光部の配光調整部材以外の部分を共用することによって、照明ユニットのコストを低減することができる。 Further, if the power distribution unit can be detached from the power supply terminal unit and the light emitting unit, the lighting unit can be folded, and can be disassembled and packed more compactly, so that handling during transportation is easy.
If the light distribution adjusting member is detachable from the seating member, excellent light distribution characteristics can be realized by attaching an appropriate light distribution adjusting member according to the environment in which the lighting unit is used. . Moreover, the cost of an illumination unit can be reduced by sharing parts other than the light distribution adjustment member of a light emission part.

また、配光調整部材は樹脂製であるとすれば、ガラス部分を有する従来ランプよりも壊れ難くすることができる。   Further, if the light distribution adjusting member is made of resin, it can be made more difficult to break than a conventional lamp having a glass portion.

以下、本発明に係る照明ユニットの実施の形態について、図面を参照しながら説明する。
［１］ 照明ユニットの構成
まず、本発明の実施の形態に係る照明ユニットの構成について説明する。
図１は、本実施の形態に係る照明ユニットの外観斜視図であって、（ａ）には照明ユニットの外観が、（ｂ）には蛍光灯用器具のソケット部分が、また、（ｃ）には本実施の形態に係る照明ユニットを蛍光灯用器具に装着した様子が、それぞれ示されている。 Hereinafter, embodiments of a lighting unit according to the present invention will be described with reference to the drawings.
[1] Configuration of Lighting Unit First, the configuration of the lighting unit according to the embodiment of the present invention will be described.
FIG. 1 is an external perspective view of an illumination unit according to the present embodiment, wherein (a) shows the appearance of the illumination unit, (b) shows a socket part of a fluorescent lamp apparatus, and (c). Each shows a state in which the illumination unit according to the present embodiment is mounted on a fluorescent lamp fixture.

図１（ａ）に示されるように、照明ユニット１は、１対の給電端子部１０１、複数の発光部１０２及び可撓配電部１０３を備えている。給電端子部１０１と発光部１０２、また、発光部１０２どうしは可撓配電部１０３によって電気的に接続されている。
給電端子部１０１は、いずれも直管型蛍光灯の口金形状をしており、それぞれ蛍光灯用器具のソケット１０４に嵌合される一対の電極端子１０１ａが突出している。蛍光灯用器具は交流電力を供給する一方、ＬＥＤを点灯させるためには直流電力が必要になるので、給電端子部１０１は整流回路を内蔵している。整流回路を給電端子部に内蔵することにより、発光部を軽量化することできるので、低い保持力でも発光部を器具に取り付けることが可能となる。また、整流回路を器具側に設けることも可能である。更に照明ユニットの軽量化することができる。給電端子部１０１が内蔵する整流回路の構成に関しては、例えば、特開２００９−８７５８８号公報を参照されたい。 As shown in FIG. 1A, the lighting unit 1 includes a pair of power supply terminal portions 101, a plurality of light emitting portions 102, and a flexible power distribution portion 103. The power supply terminal portion 101 and the light emitting portion 102, and the light emitting portions 102 are electrically connected by a flexible power distribution portion 103.
Each of the power supply terminal portions 101 has a base shape of a straight tube type fluorescent lamp, and a pair of electrode terminals 101a that are respectively fitted to the sockets 104 of the fluorescent lamp fixtures protrude. While the fluorescent lamp fixture supplies AC power, DC power is required to turn on the LED. Therefore, the power supply terminal portion 101 has a built-in rectifier circuit. Since the light emitting part can be reduced in weight by incorporating the rectifier circuit in the power supply terminal part, the light emitting part can be attached to the instrument even with a low holding force. It is also possible to provide a rectifier circuit on the appliance side. Furthermore, the weight of the lighting unit can be reduced. For the configuration of the rectifier circuit built in the power supply terminal unit 101, refer to, for example, Japanese Patent Application Laid-Open No. 2009-87588.

なお、給電端子部１０１をソケット１０４にロックする機構を給電端子部１０１に設けても良い（不図示）。
発光部１０２は、ＬＥＤを内蔵しており、可撓配電部１０３を介して給電端子部１０１から直流電力の供給を受けて発光する。図２は、発光部１０２の構成を示す図であって、（ａ）は側面図、（ｂ）は平面図、（ｃ）は正面図、（ｄ）は分解図である。 Note that a mechanism for locking the power supply terminal portion 101 to the socket 104 may be provided in the power supply terminal portion 101 (not shown).
The light emitting unit 102 has a built-in LED and emits light upon receiving DC power from the power supply terminal unit 101 via the flexible power distribution unit 103. 2A and 2B are diagrams showing a configuration of the light emitting unit 102, where FIG. 2A is a side view, FIG. 2B is a plan view, FIG. 2C is a front view, and FIG.

図２に示されるように、発光部１０２は着座部材２０１、基台２０２及び配光調整部材２０３からなっている。着座部材２０１はマグネットであって、発光部１０２は着座部材２０１によって、蛍光灯用器具を構成する金属製の反射板１０５に座着する（図１（ｃ））。
本実施の形態においては、着座部材２０１と反射板１０５とは共に平面形状となっており、磁力によって互いに密着する。したがって、発光部１０２のＬＥＤが発生させる熱が効率良く反射板１０５へ放熱される。また、着座部材２０１は基台２０２に接着、固定されている。本構成によれば、発光部の底面全体を器具に熱的に直結することにより、軽量化、小型化の障害となり得る放熱体を発光部から省くことができる。軽量化、小型化により、蛍光灯のみならず、既存のＬＥＤランプの課題を解決することができる。 As shown in FIG. 2, the light emitting unit 102 includes a seating member 201, a base 202, and a light distribution adjustment member 203. The seating member 201 is a magnet, and the light emitting unit 102 is seated on the metal reflector 105 constituting the fluorescent lamp fixture by the seating member 201 (FIG. 1C).
In the present embodiment, the seating member 201 and the reflection plate 105 are both planar and are in close contact with each other by magnetic force. Therefore, the heat generated by the LEDs of the light emitting unit 102 is efficiently radiated to the reflecting plate 105. The seating member 201 is bonded and fixed to the base 202. According to this configuration, by directly connecting the entire bottom surface of the light emitting unit to the appliance, it is possible to omit a heat radiator that can be an obstacle to weight reduction and size reduction from the light emitting unit. By reducing the weight and size, it is possible to solve the problems of not only fluorescent lamps but also existing LED lamps.

基台２０２の両端部には可撓配電部１０３を接続するためのジャック２０２ａが設けられている。また、基台２０２にはＬＥＤ２０２ｂが実装されており、直流電力の供給を受けて発光する。
基台２０２の構成部材として、金属基板、セラミック基板等の高熱伝導部材上に配線パターンをも設けたものを用いることができる。また、ポリイミド等の樹脂フィルム上に配線パターンを設けた可撓性基板を用いることができる。このようにすれば、曲面への取付けのみならず、薄いことにより放熱性と軽量化も確保できる。ジャック２０２ａはこれらの基板上に別部材を取り付けることによって設けてもよい。 Jacks 202 a for connecting the flexible power distribution unit 103 are provided at both ends of the base 202. Further, an LED 202b is mounted on the base 202, and emits light when supplied with DC power.
As a constituent member of the base 202, a member provided with a wiring pattern on a high heat conductive member such as a metal substrate or a ceramic substrate can be used. Further, a flexible substrate in which a wiring pattern is provided on a resin film such as polyimide can be used. If it does in this way, not only the attachment to a curved surface but the heat dissipation and weight reduction are also securable by being thin. The jack 202a may be provided by attaching another member on these substrates.

基台２０２に実装されたＬＥＤ２０２ｂは互いに電気的に直列に接続されても良いし、並列に接続されても良い。また、直列接続と並列接続が並存していてもよい。直列接続の場合には、直列接続されたＬＥＤ２０２ｂが多いほど駆動電圧を高くすることができるので、電源効率を高くすることができる。また、並列接続の場合には、並列接続されたＬＥＤ２０２ｂが多いほどＬＥＤの破損等による影響を低くすることができる。   The LEDs 202b mounted on the base 202 may be electrically connected to each other in series or may be connected in parallel. Moreover, series connection and parallel connection may coexist. In the case of series connection, the drive voltage can be increased as the number of LEDs 202b connected in series increases, so that the power supply efficiency can be increased. Moreover, in the case of parallel connection, the influence by damage etc. of LED can be made low, so that there are many LED202b connected in parallel.

ＬＥＤ２０２ｂの出射光量は、通電される電流量に応じて異なるので、必要な光量に応じた回路構成とすべきである。
なお、本実施例のようにパッケージに発光素子を一次実装したＬＥＤ２０２ｂを基台２０２に二次実装する形態のほか、基台２０２に発光素子を一次実装する形態でもよい。
また、ＬＥＤ２０２ｂには、青色〜ＵＶ光を発する発光素子と波長変換部材との組合せによる白色ＬＥＤ、青色、緑色、赤色を発する発光素子の組合せによる白色ＬＥＤを用いることができる。各色の強度バランスを制御することによる調色も可能となる。単色の発光素子で構成してもよい。 Since the amount of light emitted from the LED 202b varies depending on the amount of current that is energized, the circuit configuration should correspond to the necessary amount of light.
In addition to the form in which the LED 202b in which the light emitting element is primarily mounted on the package is secondarily mounted on the base 202 as in this embodiment, the form in which the light emitting element is primarily mounted on the base 202 may be used.
The LED 202b can be a white LED that is a combination of a light emitting element that emits blue to UV light and a wavelength conversion member, or a white LED that is a combination of light emitting elements that emit blue, green, and red. Toning is also possible by controlling the intensity balance of each color. You may comprise a monochromatic light emitting element.

波長変換部材には、例えばＹＡＧ蛍光体（（Ｙ，Ｇｄ）３Ａｌ５Ｏ１２：Ｃｅ３＋）、珪酸塩蛍光体（（Ｓｒ，Ｂａ）２ＳｉＯ4：Ｅｕ２＋）、窒化物蛍光体（（Ｃａ，Ｓｒ，Ｂａ）ＡｌＳｉＮ３：Ｅｕ２＋）、酸窒化物蛍光体（Ｂａ3Ｓｉ6Ｏ12Ｎ2:Ｅｕ2＋）、α-サイアロン蛍光体（Ｃａ-α-ＳｉＡｌＯＮ：Ｅｕ２＋）等を用いることができる。これら蛍光体材料をシリコーン等の樹脂材に分散したもの、ガラス等の無機材に分散したもの、セラミックに焼成したものなどを用いることができる。 Examples of the wavelength conversion member include YAG phosphor ((Y, Gd) 3 Al 5 O 12 : Ce 3+ ), silicate phosphor ((Sr, Ba) 2 SiO 4 : Eu 2+ ), and nitride phosphor (( Ca, Sr, Ba) AlSiN 3 : Eu 2+ ), oxynitride phosphor (Ba 3 Si 6 O 12 N 2 : Eu 2+ ), α-sialon phosphor (Ca-α-SiAlON: Eu 2+ ), etc. be able to. A material in which these phosphor materials are dispersed in a resin material such as silicone, a material dispersed in an inorganic material such as glass, or a material fired in ceramic can be used.

配光調整部材２０３の四隅には突起部２０３ａが形成されており、基台２０２の四隅に設けられたほぞ穴に当該突起部２０３ａを嵌合することによって、配光調整部材２０３が基台２０２に固定される。配光調整部材２０３は拡散板になっており、基台２０２に実装されたＬＥＤ２０２ｂが出射する照明光を拡散させる。
配光調整部材を基台２０２から脱着することができるので、配光調整部材の選択により、用途に応じた配光を容易に実現することができる。また、配光調整部材に波長変換機能を付与することにより、発光素子との組合せにより光色を選択、調整することも可能となる。 Protrusions 203 a are formed at the four corners of the light distribution adjusting member 203, and the light distribution adjusting member 203 is mounted on the base 202 by fitting the protrusions 203 a into mortises provided at the four corners of the base 202. Fixed to. The light distribution adjusting member 203 is a diffusion plate, and diffuses illumination light emitted from the LED 202b mounted on the base 202.
Since the light distribution adjusting member can be detached from the base 202, light distribution according to the application can be easily realized by selecting the light distribution adjusting member. Further, by providing a wavelength conversion function to the light distribution adjusting member, it is possible to select and adjust the light color depending on the combination with the light emitting element.

また、配光調整部材には、透光性樹脂、セラミック材、ガラス材等を適宜選択することができる。これらの部材表面を曲面加工、凹凸加工したり、内部や表面に光拡散材料を分散、散布することで、配光制御機能、混色機能をもたらすことが出来る。
可撓配電部１０３は、両端にプラグを備えたケーブルであって、例えば、銅線が絶縁被覆されてなる。可撓配電部１０３のプラグを給電端子部１０１や発光部１０２が備えるジャックに差し込むことによって、給電端子部１０１と発光部１０２や発光部１０２どうしが電気的に接続される。 For the light distribution adjusting member, a translucent resin, a ceramic material, a glass material, or the like can be appropriately selected. By subjecting the surface of these members to curved surface processing and uneven processing, or by dispersing and dispersing a light diffusing material inside or on the surface, it is possible to provide a light distribution control function and a color mixing function.
The flexible power distribution unit 103 is a cable having plugs at both ends, and is formed by, for example, insulating coating of copper wire. By inserting the plug of the flexible power distribution unit 103 into a jack provided in the power supply terminal unit 101 or the light emitting unit 102, the power supply terminal unit 101 and the light emitting unit 102 or the light emitting unit 102 are electrically connected.

以上、説明したような構成を備えれば、給電端子部１０１が直管型蛍光灯の口金形状をしているので、照明ユニット１を既設の蛍光灯用器具に装着することができる。
［２］ 変形例
以上、本発明を実施の形態に基づいて説明してきたが、本発明が上述の実施の形態に限定されないのは勿論であり、以下のような変形例を実施することができる。 As described above, when the configuration as described above is provided, the power supply terminal portion 101 has a base shape of a straight tube fluorescent lamp, so that the illumination unit 1 can be mounted on an existing fluorescent lamp apparatus.
[2] Modifications Although the present invention has been described based on the embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and the following modifications can be implemented. .

（１） 上記実施の形態においては、ＬＥＤを用いて照明光を発生させる場合について説明したが、本発明がこれに限定されないのは言うまでもなく、ＬＥＤ以外の固体発光素子を用いても良い。例えば、有機ＥＬ（Organic Electro Luminescence）光源を用いても良い。固体発光素子は、蛍光灯とは異なって、破損し難いので取扱いが容易であり、また、寿命が長い。したがって、ＬＥＤであろうと有機ＥＬであろうと、固体発光素子を用いれば本発明の効果を得ることができる。   (1) Although the case where illumination light is generated using an LED has been described in the above embodiment, it goes without saying that the present invention is not limited to this, and a solid light emitting element other than an LED may be used. For example, an organic EL (Organic Electro Luminescence) light source may be used. Unlike a fluorescent lamp, a solid light emitting element is easy to handle because it is not easily damaged and has a long life. Therefore, the effect of the present invention can be obtained by using a solid light emitting element, whether it is an LED or an organic EL.

（２） 上記実施の形態においては、発光部１０２の外形がかまぼこ形状である場合について説明したが、本発明がこれに限定されないのは言うまでもなく、かまぼこ形状以外の形状をとっても良い。
図３は、本変形例に係る発光部の形状を示す図である。図３（ａ）には、発光部の長手方向に沿って溝を多数設けた配光調整部材３０３ａが示されている。図３（ｂ）には、円筒形状をとる配光調整部材３０３ｂが示されている。図３（ｃ）に示された配光調整部材３０３ｃは、底面が星形の多角柱形状をとなっている。このようにすれば、発光部の長手方向に直交する方向へ照明光を拡散させることができる。 (2) In the above-described embodiment, the case where the outer shape of the light emitting unit 102 has a kamaboko shape has been described. However, it goes without saying that the present invention is not limited to this, and may take a shape other than the kamaboko shape.
FIG. 3 is a diagram showing the shape of the light emitting unit according to this modification. FIG. 3A shows a light distribution adjusting member 303a provided with a number of grooves along the longitudinal direction of the light emitting portion. FIG. 3B shows a light distribution adjusting member 303b having a cylindrical shape. The light distribution adjusting member 303c shown in FIG. 3C has a polygonal prism shape with a bottom surface. If it does in this way, illumination light can be diffused in the direction orthogonal to the longitudinal direction of a light-emitting part.

図３（ｄ）には、底面が台形の四角柱形状をとる基台３０２ｄのテーパー面上にかまぼこ形状の配光調整部材３０３ｄが固定された発光部が示されている。
図４は、図３（ｄ）に示した発光部を２つ蛍光灯用器具に装着した様子を示す断面図である。図４（ａ）は、蛍光灯用器具の反射板４０１が平板である場合の装着状態を示している。このように、２つの発光部のテーパー面が互いに反対側を向くように発光部を配置すれば、より広い範囲に照明光を行き渡らせて優れた配光を実現することができる。 FIG. 3D shows a light emitting portion in which a light distribution adjusting member 303d having a kamaboko shape is fixed on a tapered surface of a base 302d having a trapezoidal quadrangular prism shape.
FIG. 4 is a cross-sectional view showing a state where the two light emitting units shown in FIG. Fig.4 (a) has shown the mounting state when the reflecting plate 401 of the fixture for fluorescent lamps is a flat plate. In this way, if the light emitting units are arranged so that the tapered surfaces of the two light emitting units face opposite sides, it is possible to achieve excellent light distribution by spreading the illumination light over a wider range.

また、図４（ｂ）は、蛍光灯用器具の反射板４０２が尾根状に２つのテーパー面を有している場合の装着状態を示している。このような場合には、発光部のテーパー面が互いに向き合うように発光部を配置すれば、特定の方向に照明光を集中させることができる。このように、テーパー面を有する発光部を用いれば、照明の目的や蛍光灯器具の反射板の形状に合わせて適切な配光を実現することができる。   Moreover, FIG.4 (b) has shown the mounting state when the reflecting plate 402 of the fixture for fluorescent lamps has two taper surfaces in a ridge shape. In such a case, the illumination light can be concentrated in a specific direction by arranging the light emitting units so that the tapered surfaces of the light emitting units face each other. Thus, if the light emission part which has a taper surface is used, suitable light distribution can be implement | achieved according to the objective of illumination and the shape of the reflecting plate of a fluorescent lamp fixture.

また、蛍光灯用器具の反射板が平板でない場合には、反射板の形状に合った形状の着座部材を用いるのが望ましい。例えば、反射板が凹面形状である場合に、凸面形状の着座部材を用いれば、反射板と着座部材との接触面積を最大化して、方熱効率を向上させることができる。
（３） 上記実施の形態においては、直管形の蛍光灯用器具に対して平面視長方形状の発光部を用いる場合について説明したが、本発明がこれに限定されないのは言うまでもなく、他の形状の蛍光灯用器具に対しては他の形状の発光部を適用しても良い。 Moreover, when the reflecting plate of the fluorescent lamp fixture is not a flat plate, it is desirable to use a seating member having a shape that matches the shape of the reflecting plate. For example, when the reflector is concave, if a convex seating member is used, the contact area between the reflector and the seating member can be maximized and the thermal efficiency can be improved.
(3) In the above-described embodiment, the case where the light emitting part having a rectangular shape in plan view is used for the straight tube fluorescent lamp device has been described, but it goes without saying that the present invention is not limited to this. You may apply the light emission part of another shape with respect to the shape of a fluorescent lamp apparatus.

図５は、本変形例に係る照明ユニットの構成を示す平面図であって、（ａ）は環状構成の発光部を示し、（ｂ）六角形状構成の発光部を示す。図５（ａ）に示されるように、平面視において中心角６０度の円弧状の発光部５０２を６つ用いれば、丸管の蛍光灯を代替することができる。
この場合において、円弧のソケットが配される側に可撓配電体５０３を接続するためのジャックを発光部５０２に設ければ、当該ジャックに可撓配電体５０３を接続することによって、発光部５０２どうしのみならず、給電端子部５０１も同様に接続することができる。 5A and 5B are plan views showing the configuration of the illumination unit according to the present modification, in which FIG. 5A shows a light-emitting portion having an annular configuration, and FIG. 5B shows a light-emitting portion having a hexagonal configuration. As shown in FIG. 5A, a round tube fluorescent lamp can be substituted if six arc-shaped light emitting portions 502 having a central angle of 60 degrees in plan view are used.
In this case, if a jack for connecting the flexible power distribution body 503 is provided on the light emitting section 502 on the side where the arc socket is disposed, the light emitting section 502 can be obtained by connecting the flexible power distribution body 503 to the jack. Not only between them, but also the power supply terminal portion 501 can be connected in the same manner.

図５（ａ）のように、発光部５０２がなす円環の外側に蛍光灯用器具のソケットが配される場合には、発光部５０２のジャックも円弧の外側に配すべきである。逆に、発光部５０２がなす円環の内側に蛍光灯用器具のソケットが配される場合には、発光部５０２のジャックも円弧の内側に配すのが望ましい。
なお、発光部５０２がなす円弧の中心角は６０度に限定されず、他の角度としても良い。また、発光部５０２間で中心角が異なっていても、複数の発光部５０２を組み合わせることによって円環をなすことができれば良い。 As shown in FIG. 5 (a), when the fluorescent lamp socket is arranged outside the ring formed by the light emitting unit 502, the jack of the light emitting unit 502 should also be arranged outside the arc. On the contrary, when the fluorescent lamp fixture socket is arranged inside the ring formed by the light emitting unit 502, it is desirable to arrange the jack of the light emitting unit 502 inside the arc.
The central angle of the arc formed by the light emitting unit 502 is not limited to 60 degrees, and may be other angles. Further, even if the central angles are different among the light emitting units 502, it is only necessary to form a ring by combining a plurality of light emitting units 502.

図５（ｂ）に示されるように、平面視において台形形状をとる何れも同一形状の発光部５１２を６つ組み合わせると、平面視において六角形環状に発光部５１２を配置することができる。このようにすれば、円弧状の発光部５０２よりも製造が容易で、コンパクトに梱包できる。
（４） 上記実施の形態においては、着座部材２０１が磁石になっており、磁力によって反射板に吸着する場合について説明したが、本発明がこれに限定されないのは言うまでもなく、磁石に代えて、粘着テープや面ファスナ等、ネジ止めその他の取付け手段を用いても同様の効果を得ることができる。なお、粘着テープや面ファスナを用いれば、樹脂製の反射板等、磁力で吸着させることができない反射板にも発光部を取り付けることができる。 As shown in FIG. 5B, when six light emitting portions 512 having the same trapezoidal shape in plan view are combined, the light emitting portions 512 can be arranged in a hexagonal ring shape in plan view. In this way, it is easier to manufacture than the arc-shaped light-emitting portion 502 and can be packed in a compact manner.
(4) In the above embodiment, the case where the seating member 201 is a magnet and is attracted to the reflecting plate by a magnetic force has been described, but it goes without saying that the present invention is not limited to this. The same effect can be obtained by using screws or other attachment means such as an adhesive tape or hook-and-loop fastener. In addition, if an adhesive tape and a hook-and-loop fastener are used, a light emission part can be attached also to reflectors which cannot be adsorbed by magnetic force, such as a resin reflector.

また、発光部を取り付けるのが蛍光灯用器具の反射板部分に限定されないのは言うまでもなく、反射板以外の部分に発光部を取り付けても良い。反射板以外の部分に発光部を取り付ける場合でも、着座部材に磁石や粘着テープ、面ファスナ等を用いることができる。また、着脱可能な粘着剤を用いても良い。
（５） 上記実施の形態においては、可撓配電部１０３を用いて発光部１０２どうしを電気的に接続する場合について説明したが、本発明がこれに限定されないのは言うまでもなく、他の手段を用いて発光部どうしを電気的に接続しても良い。 Further, it goes without saying that the light emitting unit is not limited to the reflecting plate portion of the fluorescent lamp fixture, and the light emitting unit may be attached to a portion other than the reflecting plate. Even when the light emitting portion is attached to a portion other than the reflector, a magnet, an adhesive tape, a hook-and-loop fastener, or the like can be used for the seating member. A removable adhesive may also be used.
(5) In the above embodiment, the case where the light emitting units 102 are electrically connected to each other using the flexible power distribution unit 103 has been described, but it is needless to say that the present invention is not limited to this. It may be used to electrically connect the light emitting units.

図６は、本変形例に係る照明ユニットの構成を示す外観斜視図であって、（ａ）は発光部どうしを電気的に接続した状態を示し、（ｂ）は発光部どうしを分離させた状態を示す。図（ａ）に示されるように、照明ユニット６は、給電端子部６０１、発光部６０２及び可撓配電部６０３を供え、給電端子部６０１と発光部６０２とが可撓配電部６０３にて接続されている。給電端子部６０１は蛍光灯用器具のソケットに接続するための電極端子６０１ａを突出させている。   6A and 6B are external perspective views showing the configuration of the illumination unit according to this modification, where FIG. 6A shows a state where the light emitting units are electrically connected, and FIG. 6B shows the light emitting units separated from each other. Indicates the state. As shown in FIG. 1A, the lighting unit 6 includes a power supply terminal unit 601, a light emitting unit 602, and a flexible power distribution unit 603, and the power supply terminal unit 601 and the light emitting unit 602 are connected by the flexible power distribution unit 603. Has been. The power supply terminal portion 601 protrudes an electrode terminal 601a for connection to a socket of a fluorescent lamp fixture.

図６（ｂ）に示されるように、発光部６０２は、その一端から電極端子６１０が突出しており、もう一端には他の発光部６０２の電極端子６１０を迎えるジャック６１１が設けられている。この電極端子６１０とジャック６１１とを接続することによって、図６（ａ）に示されるように、発光部６０２を隙間無く接続することができるので、優れた配光特性を実現することができる。   As shown in FIG. 6B, the light emitting unit 602 has an electrode terminal 610 protruding from one end thereof, and a jack 611 for receiving the electrode terminal 610 of another light emitting unit 602 is provided at the other end. By connecting the electrode terminal 610 and the jack 611, as shown in FIG. 6A, the light emitting unit 602 can be connected without a gap, so that excellent light distribution characteristics can be realized.

（６） 上記実施の形態においては、基台２０２のほぞ穴に配光調整部材２０３の突起部２０３ａを嵌合させることによって、基台２０２に配光調整部材２０３を取り付ける場合について説明したが、本発明がこれに限定されないのは言うまでもなく、これに代えて他の手段を用いて基台２０２に配光調整部材２０３を取り付けても良い。
例えば、基台２０２に配光調整部材２０３を接着しても良いし、基台２０２に溝部を設けると共に、基台２０２の溝部に係合する突起部を配光調整部材２０３に設けても良い。配光調整部材２０３を基台２０２に取り付ける方法の如何に関わらず本発明の効果を得ることができる。 (6) In the above embodiment, the case where the light distribution adjustment member 203 is attached to the base 202 by fitting the projection 203a of the light distribution adjustment member 203 into the mortise of the base 202 has been described. Needless to say, the present invention is not limited to this, and the light distribution adjusting member 203 may be attached to the base 202 using other means instead.
For example, the light distribution adjusting member 203 may be bonded to the base 202, or a groove portion may be provided on the base 202, and a protrusion that engages with the groove portion of the base 202 may be provided on the light distribution adjusting member 203. . The effect of the present invention can be obtained regardless of the method of attaching the light distribution adjusting member 203 to the base 202.

（７） 上記実施の形態においては、特に言及しなかったが、発光部を構成する配光調整部材は、例えば、樹脂中に照明光を拡散させる拡散片（例えば、金属箔、ビーズ、酸化金属粒子等。）が封入されてなる。また、基台は、例えば、ＬＥＤを点灯させるための回路が樹脂中に封入されたものである。マグネットは磁気を帯びた磁性体片である。このように、衝撃によって壊れ難い材料を用いれば、照明ユニットを更に取り扱い易くすることができる。   (7) Although not particularly mentioned in the above embodiment, the light distribution adjusting member constituting the light emitting unit is, for example, a diffusion piece (for example, metal foil, beads, metal oxide) that diffuses illumination light into the resin. Particles etc.) are enclosed. The base is, for example, a circuit in which a circuit for lighting an LED is enclosed in a resin. The magnet is a magnetic piece with magnetism. Thus, if a material that is not easily broken by an impact is used, the lighting unit can be made easier to handle.

（８） 上記実施の形態においては、基台の反射板側の全面を着座部材にて被う場合について説明したが、本発明がこれに限定されないのは言うまでもなく、例えば、基台の四隅に磁石を埋め込むなど、磁石にて全面を被わなくても本発明の効果を得ることができる。これは、磁石以外の手段にて発光部を蛍光灯用器具に取り付ける場合も同様である。
（９） 上記実施の形態においては、発光部どうしを直列に接続する場合について説明したが、本発明がこれに限定されないのは言うまでもなく、直列に代えて、或いは直列に加えて、発光部どうしを並列に接続しても良い。発光部どうしの接続の仕方については、照明ユニットを適用する蛍光灯用器具の種類や望ましい配光特性などを考慮して決定すべきである。 (8) In the above embodiment, the case where the entire surface of the base on the reflecting plate side is covered with the seating member has been described, but it goes without saying that the present invention is not limited to this, for example, at the four corners of the base. The effect of the present invention can be obtained without covering the entire surface with a magnet such as embedding a magnet. The same applies to the case where the light emitting part is attached to the fluorescent lamp fixture by means other than the magnet.
(9) In the above embodiment, the case where the light emitting units are connected in series has been described. However, it goes without saying that the present invention is not limited to this, and the light emitting units are used instead of or in series. May be connected in parallel.
