Description

ＬＥＤ照明装置LED lighting device
　本発明は、ＬＥＤ照明装置に関する。 The present invention relates to an LED lighting device.
　特許文献１には、従来のＬＥＤ照明装置の一例が開示されている。同文献に開示されたＬＥＤ照明装置は、長矩形状の基板と、基板上に実装された複数のＬＥＤチップと、基板を収容する管と、端子と、ＬＥＤチップを点灯させるための回路とを備えている。基板上には複数のＬＥＤチップおよび端子に接続される配線が形成されている。このＬＥＤ照明装置は、端子を一般用蛍光灯照明器具のソケットの差込口に嵌合させることにより、複数のＬＥＤチップを発光させることができるように構成されている。 Patent Document 1 discloses an example of a conventional LED lighting device. The LED lighting device disclosed in the document includes a long rectangular substrate, a plurality of LED chips mounted on the substrate, a tube that accommodates the substrate, a terminal, and a circuit for lighting the LED chip. ing. A plurality of LED chips and wirings connected to the terminals are formed on the substrate. This LED illuminating device is configured so that a plurality of LED chips can emit light by fitting a terminal into an insertion port of a socket of a general fluorescent lamp luminaire.
　しかしながら、一般用蛍光灯照明器具のソケットを用いることなく、天井に設置可能なＬＥＤ照明装置が求められる場合がある。このような場合であっても、設置や部品の交換に際して、適切に作業を行うことが可能であることが求められる。 However, there is a case where an LED lighting device that can be installed on a ceiling without using a socket of a general fluorescent lamp lighting fixture is required. Even in such a case, it is required that work can be appropriately performed during installation and replacement of parts.
　省電力化を目的として、蛍光灯に代わる照明手段としてＬＥＤ発光部を有するＬＥＤ照明灯が提案されている。図３９は、従来のＬＥＤ照明灯の一例を示している（特許文献２参照）。同図に示すＬＥＤ照明灯Ｘは、支持部材９１、ＬＥＤ発光部９２、透光カバー９３および電源部９４を備えている。透光カバー９３は、円筒形状であり、支持部材９１、複数のＬＥＤ発光部９２および電源部９４を収容している。支持部材９１は、ＬＥＤ発光部９２を支持ており、ＬＥＤ発光部９２からの放熱を促進する機能を果たしうる。ＬＥＤ発光部９２は、透光カバー９３の軸方向に沿って支持部材９１上に配列された複数のＬＥＤモジュールと、これらのＬＥＤモジュールを支持する基板からなる。電源部９４は、たとえば商用の１００Ｖ電力をＬＥＤ発光部９２の発光に適した直流電力に変換する。透光カバー９３は、ＬＥＤ発光部９２からの光を拡散させつつ透過させるものであり、たとえば透明な樹脂材料に白色などの拡散材が混入された材質からなる。ＬＥＤ照明灯Ｘは、一般的な直管形蛍光灯の代替品として用いられる。支持部材９１および透光カバー９３の両端には、一対の口金（図示略）が設けられる。これらの口金は、ＬＥＤ照明灯Ｘを照明器具に取り付けるために用いられる。 For the purpose of power saving, an LED illumination lamp having an LED light emitting unit has been proposed as an illumination means instead of a fluorescent lamp. FIG. 39 shows an example of a conventional LED illumination lamp (see Patent Document 2). The LED illuminating lamp X shown in the figure includes a support member 91, an LED light emitting unit 92, a translucent cover 93, and a power supply unit 94. The translucent cover 93 has a cylindrical shape and houses a support member 91, a plurality of LED light emitting units 92, and a power supply unit 94. The support member 91 supports the LED light emitting unit 92 and can fulfill the function of promoting heat dissipation from the LED light emitting unit 92. The LED light emitting unit 92 includes a plurality of LED modules arranged on the support member 91 along the axial direction of the translucent cover 93 and a substrate that supports these LED modules. The power supply unit 94 converts, for example, commercial 100V power into DC power suitable for the light emission of the LED light emitting unit 92. The translucent cover 93 is to transmit the light from the LED light emitting unit 92 while diffusing, and is made of, for example, a material in which a diffusing material such as white is mixed in a transparent resin material. The LED illumination lamp X is used as a substitute for a general straight tube fluorescent lamp. A pair of caps (not shown) are provided at both ends of the support member 91 and the translucent cover 93. These caps are used to attach the LED lighting X to the lighting fixture.
　支持部材９１と透光カバー９３とは、互いに異なる材質からなることが一般的である。支持部材９１が金属からなり、透光カバー９３が樹脂からなる場合、ＬＥＤ照明灯Ｘの使用時における温度変化によって、支持部材９１と透光カバー９３の熱膨張または熱収縮に差異が生じる。このため、前記口金に対して、支持部材９１と透光カバー９３が別々に相対動するような挙動を示す。この挙動が過度に生じると、たとえば透光カバー９３と前記口金との間に隙間が生じるおそれがある。このようなことでは、透光カバー９３内に湿気や水分が浸入してしまうことが懸念される。 The support member 91 and the translucent cover 93 are generally made of different materials. When the support member 91 is made of metal and the translucent cover 93 is made of resin, a difference in thermal expansion or contraction between the support member 91 and the translucent cover 93 occurs due to a temperature change when the LED lighting lamp X is used. For this reason, the support member 91 and the translucent cover 93 exhibit a behavior that moves relative to the base separately. If this behavior occurs excessively, there may be a gap between the translucent cover 93 and the base, for example. In such a case, there is a concern that moisture or moisture may enter the translucent cover 93.
　ＬＥＤ発光部９２から出射された光は、透光カバー９３を透過するものと、透光カバー９３の内面によって反射されるものとに分けられる。透光カバー９３の内面によって反射された光がいずれかの部位によって吸収されてしまうと、ＬＥＤ照明灯Ｘの輝度が低下してしまう。 The light emitted from the LED light emitting unit 92 is classified into one that is transmitted through the light transmitting cover 93 and one that is reflected by the inner surface of the light transmitting cover 93. If the light reflected by the inner surface of the translucent cover 93 is absorbed by any part, the brightness | luminance of LED lighting X will fall.

　本発明によれば、前記アーム部が閉状態をとることにより、前記ＬＥＤユニットが近接状態をとっている。前記アーム部には、前記弾性部材から閉方向への弾性力が付与されるため、近接状態が安定的に維持される。この結果、通常の使用時には、前記ＬＥＤユニットが前記支持体に対して安定して固定される。一方、前記ＬＥＤユニットの設置作業や前記ＬＥＤユニットのいずれかの構成要素を交換する作業などを行う際には、使用者が前記弾性部材の弾性力を上回る力で前記ＬＥＤユニットを前記支持体から離間させようとすると、前記アーム部が開状態をとる。これにより、前記ＬＥＤユニットは、前記支持体から離間した離間状態をとる。この際、前記係合部材が前記アーム部と係合するため、前記ＬＥＤユニットが、前記支持体から誤って落下することなどを防止することができる。したがって、前記ＬＥＤ照明装置によれば、設置や交換の作業を適切に行うことが可能である。 According to the present invention, the LED unit is in the proximity state by the arm portion being in the closed state. Since the elastic force in the closing direction is applied from the elastic member to the arm portion, the proximity state is stably maintained. As a result, during normal use, the LED unit is stably fixed to the support. On the other hand, when performing an installation operation of the LED unit, an operation of replacing any component of the LED unit, or the like, the user removes the LED unit from the support with a force exceeding the elastic force of the elastic member. If it tries to separate, the said arm part will take an open state. Thereby, the said LED unit takes the separated state spaced apart from the said support body. At this time, since the engaging member engages with the arm portion, it is possible to prevent the LED unit from being accidentally dropped from the support. Therefore, according to the LED lighting device, it is possible to appropriately perform installation and replacement work.

FIG. 3 is an enlarged cross-sectional view of a main part taken along line III-III in FIG. 4 is a cross-sectional view taken along line IV-IV in FIG.
　ベース１は、天井などに取り付けられるものであり、且つＬＥＤユニット２を支持するものである。図６は、ベース１を示す平面図である。ベース１は、本発明で言う支持体の一例に相当する。本実施形態のベース１は、溝部１１、一対の斜面部１２、貫通孔１３，１４および中間ケーブル１６を有している。 The base 1 is attached to a ceiling or the like and supports the LED unit 2. FIG. 6 is a plan view showing the base 1. The base 1 corresponds to an example of a support referred to in the present invention. The base 1 of the present embodiment has a groove portion 11, a pair of slope portions 12, through holes 13 and 14, and an intermediate cable 16.
　ベース１は、たとえば金属板を折り曲げ加工等することによって形成されている。ベース１のｘ方向の長さは、たとえば１２５０ｍｍ程度であり、ｙ方向の幅はたとえば２３０ｍｍ程度である。 The base 1 is formed, for example, by bending a metal plate. The length of the base 1 in the x direction is, for example, about 1250 mm, and the width in the y direction is, for example, about 230 mm.
　溝部１１は、ＬＥＤユニット２を収容する部位である。溝部１１は、ｚ方向に凹んでおり、ｘ方向に長く延びている。一対の斜面部１２は、溝部１１のｙ方向両端に繋がっており、ｙ方向外方に位置している。斜面部１２は、ｙ方向において溝部１１から離間するほど、図中ｚ方向上方（ＬＥＤユニット２の出射方向とは反対側）に位置するように傾斜している。 The groove 11 is a part that houses the LED unit 2. The groove 11 is recessed in the z direction and extends long in the x direction. The pair of inclined surface portions 12 are connected to both ends of the groove portion 11 in the y direction, and are located outward in the y direction. The inclined surface portion 12 is inclined so as to be positioned higher in the z direction (opposite to the emission direction of the LED unit 2) in the figure as it is separated from the groove portion 11 in the y direction.
　貫通孔１３，１４は、ベース１の溝部１１をｚ方向に貫通している。本実施形態においては、貫通孔１３は、ベース１のｘ方向中央に位置している。貫通孔１３は、ＬＥＤ照明装置Ａ１の取付対象部位である天井などに設けられた電源ケーブル８１を挿通させるものである。これにより、電源ケーブル８１は、溝部１１の外方から溝部１１の内方へと導かれる。貫通孔１４は、ベース１のｘ方向図中右側に位置している。貫通孔１４は、後述するＬＥＤユニット２の電源部５のケーブル５１を挿通させるものである。これにより、ケーブル５１は、溝部１１の外方から溝部１１の内方へと導かれる。 The through holes 13 and 14 penetrate the groove 11 of the base 1 in the z direction. In the present embodiment, the through hole 13 is located at the center of the base 1 in the x direction. The through-hole 13 is for inserting a power cable 81 provided on a ceiling or the like, which is an attachment target part of the LED lighting device A1. As a result, the power cable 81 is guided from the outside of the groove 11 to the inside of the groove 11. The through hole 14 is located on the right side of the base 1 in the x direction view. The through-hole 14 is for inserting a cable 51 of the power supply unit 5 of the LED unit 2 described later. As a result, the cable 51 is guided from the outside of the groove 11 to the inside of the groove 11.
　中間ケーブル１６は、後述するＬＥＤユニット２の電源部５のケーブル５１と接続されるものである。また、中間ケーブル１６の根元には端子台が設けられている。この端子台に電源ケーブル８１が接続されることにより、電源ケーブル８１と中間ケーブル１６とが導通する。中間ケーブル１６は、貫通孔１３を挟んでＬＥＤユニット２の電源部５とはｘ方向において反対側に設けられている。 The intermediate cable 16 is connected to a cable 51 of the power supply unit 5 of the LED unit 2 described later. A terminal block is provided at the base of the intermediate cable 16. By connecting the power cable 81 to this terminal block, the power cable 81 and the intermediate cable 16 are electrically connected. The intermediate cable 16 is provided on the opposite side in the x direction from the power supply unit 5 of the LED unit 2 with the through hole 13 interposed therebetween.

The LED module 20 includes a lead 21, an LED chip 22, a sealing resin 23, and a reflector 24. The pair of leads 21 is made of, for example, a Cu alloy, and an LED chip 22 is mounted on one of the leads. The surface of the lead 21 opposite to the surface on which the LED chip 22 is mounted is a mounting terminal used for surface mounting the LED module 20.
　ＬＥＤチップ２２は、ＬＥＤモジュール２０の光源であり、たとえば青色光を発光可能とされている。封止樹脂２３は、ＬＥＤチップ２２を保護するためのものである。封止樹脂２３は、ＬＥＤチップ２２からの光によって励起されることにより黄色光を発する蛍光物質を含む透光樹脂を用いて形成されている。これにより、ＬＥＤモジュール２０は、白色を照射することができる。上記蛍光物質としては、黄色光を発するものに代えて、赤色光を発するものと緑色光を発するものとを混合して用いてもよい。リフレクタ２４はたとえば白色樹脂からなり、ＬＥＤチップ２２から側方に発された光を上方に反射するためのものである。 The LED chip 22 is a light source of the LED module 20 and can emit blue light, for example. The sealing resin 23 is for protecting the LED chip 22. The sealing resin 23 is formed using a translucent resin containing a fluorescent material that emits yellow light when excited by light from the LED chip 22. Thereby, the LED module 20 can irradiate white. As said fluorescent substance, it may replace with what emits yellow light, and may mix and use what emits red light, and what emits green light. The reflector 24 is made of, for example, white resin, and reflects light emitted from the LED chip 22 to the side.
　基板３５は、ｘ方向を長手方向、ｙ方向を幅方向とする帯状であり、たとえばセラミックスあるいはガラスエポキシ樹脂からなる。本実施形態においては、基板３５には、複数のＬＥＤモジュール２０がｘ方向に沿って一列に搭載されている。 The substrate 35 has a strip shape with the x direction as the longitudinal direction and the y direction as the width direction, and is made of, for example, ceramics or glass epoxy resin. In the present embodiment, a plurality of LED modules 20 are mounted on the substrate 35 in a line along the x direction.
　支持部材３は、基板３５を支持している。支持部材３は、ｘ方向に延びている。また、支持部材３は、ｘ方向に対して直角である断面形状が一定である。本実施形態においては、支持部材３は、金属板を折り曲げ加工することによって形成されている。支持部材３には、貫通孔３３が設けられている。 The support member 3 supports the substrate 35. The support member 3 extends in the x direction. Further, the support member 3 has a constant cross-sectional shape that is perpendicular to the x direction. In the present embodiment, the support member 3 is formed by bending a metal plate. The support member 3 is provided with a through hole 33.
　支持部材３は、支持板部３１および一対の側板部３２を有している。支持板部３１は、ｘ方向を長手方向、ｙ方向を幅方向とする帯板状であり、基板３５を支持する部位である。一対の側板部３２は、支持板部３１のｙ方向両側端からベース１側に起立している。側板部３２のｚ方向端部は、折り返されている。 The support member 3 has a support plate portion 31 and a pair of side plate portions 32. The support plate portion 31 has a strip shape with the x direction as the longitudinal direction and the y direction as the width direction, and is a part that supports the substrate 35. The pair of side plate portions 32 stands on the base 1 side from both ends in the y direction of the support plate portion 31. The z direction end portion of the side plate portion 32 is folded back.
　カバー４は、ＬＥＤモジュール２０のＬＥＤチップ２２からの光を透過させる。また、本実施形態においては、カバー４は、ＬＥＤモジュール２０のＬＥＤチップ２２からの光を拡散させつつ透過させる。より具体的には、カバー４は、乳白色の半透明の樹脂からなる。カバー４は、ｘ方向に対して直角である断面形状が一定である。また、本実施形態においては、カバー４は、ｚ方向視において支持部材３よりも大である。 The cover 4 transmits light from the LED chip 22 of the LED module 20. In the present embodiment, the cover 4 transmits light from the LED chip 22 of the LED module 20 while diffusing it. More specifically, the cover 4 is made of milky white translucent resin. The cover 4 has a constant cross-sectional shape that is perpendicular to the x direction. In the present embodiment, the cover 4 is larger than the support member 3 when viewed in the z direction.
　図示された例においては、カバー４は、膨出部４１および一対の係合部４２を有する。膨出部４１は、ｚ方向においてベース１とは反対側に膨出している。一対の係合部４２は、支持部材３の一対の側板部３２と係合する部位である。係合部４２は、たとえば膨出部４１からｚ方向図中上方に起立した部位の先端部分が折り返された形状とされている。 In the illustrated example, the cover 4 has a bulging portion 41 and a pair of engaging portions 42. The bulging portion 41 bulges on the opposite side to the base 1 in the z direction. The pair of engaging portions 42 are portions that engage with the pair of side plate portions 32 of the support member 3. The engaging portion 42 has, for example, a shape in which a tip portion of a portion that stands up in the z-direction diagram from the bulging portion 41 is folded.
　電源部５は、たとえば商用ＡＣ１００Ｖ電力をＬＥＤモジュール２０のＬＥＤチップ２２を発行させるのに適したＤＣ３６Ｖないしは２４Ｖに変換する機能を果たすものである。電源部５は、支持部材３の支持板部３１と一対の側板部３２に囲まれた空間に配置されており、基板３５とは支持板部３１を挟んで反対側に位置している。また、電源部５は、図２および図６に示すように、ベース１のｘ方向一方寄りに配置されている。図４に示すように、電源部５と基板３５とは、ＬＥＤケーブル２９によって接続されている。ＬＥＤケーブル２９は、支持部材３の貫通孔３３を通じて配置されている。 The power supply unit 5 functions to convert commercial AC 100V power into DC 36V or 24V suitable for issuing the LED chip 22 of the LED module 20, for example. The power supply unit 5 is disposed in a space surrounded by the support plate portion 31 and the pair of side plate portions 32 of the support member 3, and is located on the opposite side of the support plate portion 31 with respect to the substrate 35. Further, the power supply unit 5 is disposed closer to one side in the x direction of the base 1 as shown in FIGS. 2 and 6. As shown in FIG. 4, the power supply unit 5 and the substrate 35 are connected by an LED cable 29. The LED cable 29 is disposed through the through hole 33 of the support member 3.
　取付手段６は、ベース１に対してＬＥＤユニット２を固定するとともに、ＬＥＤユニット２をベース１に対して意図した距離をおいて離間させた状態を維持するためのものである。かかる意図により、取付手段６は、ＬＥＤユニット２にベース１に対してｚ方向において近接する近接状態と、ＬＥＤユニット２にベース１に対してｚ方向において離間する離間状態と、をとらせる。本実施形態においては、２つの取付手段６がｘ方向に互いに離間して配置されている。 The attachment means 6 is for fixing the LED unit 2 to the base 1 and maintaining the state where the LED unit 2 is separated from the base 1 at an intended distance. Due to this intention, the attachment means 6 causes the LED unit 2 to take a proximity state in which the LED unit 2 is close to the base 1 in the z direction and a LED unit 2 to be separated from the base 1 in the z direction. In the present embodiment, the two attachment means 6 are arranged apart from each other in the x direction.
　取付手段６は、アーム部６１、捻じりバネ６２、固定部材６３および係合部材６５を有する。 The mounting means 6 includes an arm portion 61, a torsion spring 62, a fixing member 63, and an engaging member 65.

　アーム部６１は、固定部材６３を介して、ベース１に開閉可能に取り付けられている。アーム部６１は、たとえば金属または樹脂からなる。金属材料の例としては、ステンレス鋼などの剛体としての金属、またはバネ鋼などの弾性挙動を顕著に示す金属が挙げられる。 The arm portion 61 is attached to the base 1 through a fixing member 63 so as to be opened and closed. The arm portion 61 is made of, for example, metal or resin. Examples of the metal material include a metal as a rigid body such as stainless steel or a metal remarkably exhibiting elastic behavior such as spring steel.
　図２および図３は、アーム部６１が閉状態をとった状態を示している。また、図１９は、アーム部６１が開状態をとった状態を示している。図２および図３に示すように、アーム部６１が閉状態をとると、ＬＥＤユニット２が近接状態をとる。一方、図１９に示すように、アーム部６１が開状態をとると、ＬＥＤユニット２が離間状態をとる。 2 and 3 show a state in which the arm portion 61 is in a closed state. FIG. 19 shows a state in which the arm portion 61 is in an open state. As shown in FIGS. 2 and 3, when the arm portion 61 is in the closed state, the LED unit 2 is in the proximity state. On the other hand, as shown in FIG. 19, when the arm part 61 takes an open state, the LED unit 2 takes a separated state.
　アーム部６１は、円弧状部６１１、係合部６１２および１対の側板部６１３を有する。円弧状部６１１は、閉状態においてＬＥＤユニット２側に凸である円弧形状をなしている。係合部６１２は、アーム部６１の先端に設けられており、係合部材６５と係合する。図示された例においては、係合部６１２は、アーム部６１の先端部分が折られることによって形成されている。一対の側板部６１３は、円弧状部６１１の根元側に繋がっている。一対の側板部６１３の各々には、貫通孔６１４が設けられている。貫通孔６１４には、軸部材６６が挿通される。 The arm portion 61 includes an arc-shaped portion 611, an engaging portion 612, and a pair of side plate portions 613. The arc-shaped portion 611 has an arc shape that is convex toward the LED unit 2 in the closed state. The engaging portion 612 is provided at the tip of the arm portion 61 and engages with the engaging member 65. In the illustrated example, the engaging portion 612 is formed by folding the tip portion of the arm portion 61. The pair of side plate portions 613 are connected to the base side of the arc-shaped portion 611. Each of the pair of side plate portions 613 is provided with a through hole 614. The shaft member 66 is inserted through the through hole 614.
　捻じりバネ６２は、アーム部６１に対して閉方向に向かう弾性力を付与するものであり、本発明で言う弾性部材の一例である。捻じりバネ６２の一端は固定部材６３に作用力および反作用力を付与可能に接しまたは固定されており、他端はアーム部６１に作用力および反作用力を付与可能に接しまたは固定されている。捻じりバネ６２は、閉状態にあるアーム部６１に閉方向の弾性力を付与するように設定および配置されていることが好ましい。 The torsion spring 62 applies an elastic force toward the closing direction to the arm portion 61, and is an example of an elastic member referred to in the present invention. One end of the torsion spring 62 is in contact with or fixed to the fixing member 63 so as to be able to apply an acting force and a reaction force, and the other end is in contact with or fixed to the arm portion 61 so as to be able to apply an acting force and a reaction force. The torsion spring 62 is preferably set and arranged so as to apply an elastic force in the closing direction to the arm portion 61 in the closed state.
　固定部材６３は、アーム部６１をベース１に対して取り付けるためのものであり、ベース１に固定されている。固定部材６３は、溝状部６３１および一対の貫通孔６３２を有する。溝状部６３１は、捻じりバネ６２の一端を収容している。一対の貫通孔６３２は、軸部材６６が挿通される。アーム部６１および固定部材６３の双方に軸部材６６が挿通されることにより、アーム部６１は、固定部材６３に対して開閉可能に支持されている。また、
固定部材６３には、貫通孔６３３が形成されている。固定部材６３をベース１に固定するには、たとえばビス、リベットまたはボルトなどを貫通孔６３３に挿通し、これらをベース１に固定する手法を採用できる。 The fixing member 63 is for attaching the arm portion 61 to the base 1 and is fixed to the base 1. The fixing member 63 has a groove-shaped portion 631 and a pair of through holes 632. The groove-shaped portion 631 accommodates one end of the torsion spring 62. The shaft member 66 is inserted through the pair of through holes 632. By inserting the shaft member 66 into both the arm portion 61 and the fixing member 63, the arm portion 61 is supported so as to be openable and closable with respect to the fixing member 63. Also,
A through hole 633 is formed in the fixing member 63. In order to fix the fixing member 63 to the base 1, for example, a method of inserting screws, rivets, bolts or the like into the through holes 633 and fixing them to the base 1 can be employed.
　係合部材６５は、ＬＥＤユニット２に固定されており、アーム部６１の係合部６１２と係合する部位である。係合部材６５は、窓部６５１を有している。窓部６５１は、たとえば矩形状であり、アーム部６１が挿通されている。本実施形態においては、取付手段６によるＬＥＤユニット２の支持位置とＬＥＤユニット２のｘ方向端との距離Ｄは、ＬＥＤユニット２のｘ方向の長さＬの３％以上２５％以下である。なお、取付手段６によるＬＥＤユニット２の支持位置は、本実施形態においては、係合部材６５の窓部６５１においてアーム部６１が当接するため、窓部６５１の位置として定義される。 The engaging member 65 is fixed to the LED unit 2 and is a part that engages with the engaging part 612 of the arm part 61. The engaging member 65 has a window portion 651. The window portion 651 has, for example, a rectangular shape, and the arm portion 61 is inserted therethrough. In this embodiment, the distance D between the support position of the LED unit 2 by the attachment means 6 and the x-direction end of the LED unit 2 is 3% or more and 25% or less of the length L of the LED unit 2 in the x direction. In the present embodiment, the support position of the LED unit 2 by the attachment means 6 is defined as the position of the window portion 651 because the arm portion 61 contacts the window portion 651 of the engaging member 65.
　本実施形態においては、アーム部６１は、ｘ方向およびｚ方向を含む平面において回動する。アーム部６１は、閉状態であるときにベース１にｚ方向において最も近接し、開状態であるときにｚ方向においてベース１から最も離間する。アーム部６１は、閉状態であるときにｘ方向に沿った姿勢をとる。アーム部６１は、開状態であるときにｚ方向に沿った姿勢をとる。 In the present embodiment, the arm portion 61 rotates on a plane including the x direction and the z direction. The arm portion 61 is closest to the base 1 in the z direction when in the closed state, and is most separated from the base 1 in the z direction when in the open state. The arm portion 61 takes a posture along the x direction when in the closed state. The arm portion 61 takes a posture along the z direction when it is in the open state.
　次に、ＬＥＤ照明装置Ａ１の作用について説明する。 Next, the operation of the LED lighting device A1 will be described.
　本実施形態によれば、図２および図３に示す状態においては、アーム部６１が閉状態をとることにより、ＬＥＤユニット２が近接状態をとっている。アーム部６１には、捻じりバネ６２から閉方向への弾性力が付与されるため、近接状態が安定的に維持される。この結果、通常の使用時には、ＬＥＤユニット２がベース１に対して安定して固定される。一方、ＬＥＤユニット２の設置作業やＬＥＤユニット２のいずれかの構成要素を交換する作業などを行う際には、使用者が捻じりバネ６２の弾性力を上回る力でＬＥＤユニット２をベース１から離間させようとすると、アーム部６１が開状態に向かい、図１９に示す開状態をとる。これにより、ＬＥＤユニット２は、ベース１から離間した離間状態をとる。この際、係合部材６５がアーム部６１と係合するため、ＬＥＤユニット２が、ベース１から誤って落下することなどを防止することができる。したがって、ＬＥＤ照明装置Ａ１によれば、設置や交換の作業を適切に行うことが可能である。 According to the present embodiment, in the state shown in FIGS. 2 and 3, the LED unit 2 is in the proximity state by the arm portion 61 being in the closed state. Since the elastic force in the closing direction is applied to the arm portion 61 from the torsion spring 62, the proximity state is stably maintained. As a result, the LED unit 2 is stably fixed to the base 1 during normal use. On the other hand, when performing an installation operation of the LED unit 2 or an operation of replacing any component of the LED unit 2, the user removes the LED unit 2 from the base 1 with a force exceeding the elastic force of the torsion spring 62. If it is going to separate, the arm part 61 will go to an open state, and will take the open state shown in FIG. As a result, the LED unit 2 is separated from the base 1. At this time, since the engaging member 65 is engaged with the arm portion 61, the LED unit 2 can be prevented from being accidentally dropped from the base 1. Therefore, according to the LED illumination device A1, it is possible to appropriately perform installation and replacement work.
　アーム部６１とは別体とされた弾性部材としての捻じりバネ６２を備えることにより、捻じりバネ６２は、弾性力を発揮する機能のみが担保されればよい。たとえば、アーム部６１と捻じりバネ６２とを一体的に形成すると、アーム部６１に相当する箇所にも弾性力を発揮することが求められる。しかしながら、アーム部６１および捻じりバネ６２をたとえば、バネ鋼などによって一体的に形成すると、開閉の動作において塑性変形してしまうことが懸念される。本実施形態においては、アーム部６１には、弾性力の発揮が不要であるため、アーム部６１として適切な剛性を有しうる構成とすることができる。また、捻じりバネ６２は、意図しない塑性変形を生じない構成を選択することができる。 By providing the torsion spring 62 as an elastic member separated from the arm portion 61, the torsion spring 62 only needs to have a function of exerting an elastic force. For example, when the arm portion 61 and the torsion spring 62 are integrally formed, it is required to exert an elastic force at a portion corresponding to the arm portion 61. However, if the arm portion 61 and the torsion spring 62 are integrally formed of, for example, spring steel, there is a concern that plastic deformation may occur during the opening / closing operation. In the present embodiment, since the arm portion 61 does not need to exhibit an elastic force, the arm portion 61 can be configured to have appropriate rigidity. Further, the torsion spring 62 can be selected from a configuration that does not cause unintended plastic deformation.
　なお、アーム部６１をバネ鋼によって形成した場合、図１８に示す閉状態と開状態との間の状態において、アーム部６１の先端がＬＥＤユニット２に干渉しかけても、アーム部６１が撓むことにより、この干渉を回避することができる。この結果、アーム部６１の長さをより長くすることができる。これは、離間状態におけるベース１とＬＥＤユニット２との距離を拡大するのに適している。 When the arm portion 61 is formed of spring steel, the arm portion 61 bends even when the tip of the arm portion 61 interferes with the LED unit 2 in the state between the closed state and the open state shown in FIG. Therefore, this interference can be avoided. As a result, the length of the arm part 61 can be made longer. This is suitable for increasing the distance between the base 1 and the LED unit 2 in the separated state.
　円弧状部６１１を有することにより、開状態においても、ＬＥＤユニット２の係合部材６５に安定して係合することができる。アーム部６１の先端に係合部６１２を設けておくことは、安定した係合に好ましい。 By having the arcuate portion 611, the engagement member 65 of the LED unit 2 can be stably engaged even in the open state. Providing the engaging portion 612 at the tip of the arm portion 61 is preferable for stable engagement.
　開状態となったアーム部６１に付与される捻じりバネ６２からの弾性力は、アーム部６１の先端をｘ方向外方へと向かわせる方向に働く。この方向の力は、ＬＥＤユニット２を直ちにｚ方向上方へと向かわせるようには作用しない。このため、使用者がＬＥＤユニット２を下降させることによってＬＥＤユニット２に離間状態をとらせると、捻じりバネ６２からの弾性力が作用しつつも、ＬＥＤユニット２の離間状態が維持される。 The elastic force from the torsion spring 62 applied to the arm portion 61 in the open state acts in a direction that causes the tip of the arm portion 61 to be directed outward in the x direction. The force in this direction does not act to immediately turn the LED unit 2 upward in the z direction. For this reason, when the user lowers the LED unit 2 to bring the LED unit 2 into the separated state, the separated state of the LED unit 2 is maintained while the elastic force from the torsion spring 62 acts.
　ｘ方向に離間して配置された２つの取付手段６を備えることにより、ＬＥＤユニット２を安定して支持することができる。また、離間状態においては、２つの取付手段６において、アーム部６１の先端をｘ方向外方にそれぞれ向かわせる弾性力が付勢されている。これにより、ＬＥＤユニット２をｘ方向においてより安定して支持しておくことができる。 The LED unit 2 can be stably supported by including the two attachment means 6 that are spaced apart in the x direction. Further, in the separated state, the two attachment means 6 are biased by elastic forces that respectively direct the tips of the arm portions 61 outward in the x direction. Thereby, the LED unit 2 can be supported more stably in the x direction.
　距離Ｄが、長さＬの３％以上２５％以下であることにより、ＬＥＤユニット２をより安定して支持することができる。 When the distance D is 3% or more and 25% or less of the length L, the LED unit 2 can be supported more stably.
　ベース１の貫通孔１３には、電源ケーブル８１が導かれる。この貫通孔１３とＬＥＤユニット２の電源部５とをｘ方向において重ならないように配置することにより、電源部５と電源ケーブル８１とが干渉することを回避することが可能である。これは、ＬＥＤ照明装置Ａ１のｚ方向高さを低くするのに適している。 The power cable 81 is guided to the through hole 13 of the base 1. By disposing the through hole 13 and the power supply unit 5 of the LED unit 2 so as not to overlap each other in the x direction, it is possible to avoid interference between the power supply unit 5 and the power supply cable 81. This is suitable for reducing the height in the z direction of the LED lighting device A1.
　図２０は、ＬＥＤユニット２の変形例を示す断面図である。 FIG. 20 is a cross-sectional view showing a modification of the LED unit 2.
　本変形例においては、支持部材３がアルミなどの押出成形によって形成されている。支持部材３は、断面略コの字状である。また、電源部５は、支持部材３の支持板部３１および一対の側板部３２によって囲まれた空間に、その全体が収容されている。また、カバー４のｙ方向寸法は、支持部材３と略同じとされている。このような変形例であっても、設置や交換の作業を適切に行うことが可能である。 In this modification, the support member 3 is formed by extrusion molding such as aluminum. The support member 3 has a substantially U-shaped cross section. Further, the power supply unit 5 is entirely accommodated in a space surrounded by the support plate portion 31 and the pair of side plate portions 32 of the support member 3. The y-direction dimension of the cover 4 is substantially the same as that of the support member 3. Even in such a modification, it is possible to appropriately perform installation and replacement work.

The LED light emitting unit 2 of the present embodiment includes a plurality of LED modules 20 and a substrate 27. The substrate 27 is a printed wiring board made of, for example, glass epoxy resin, and has a long rectangular shape.
　複数のＬＥＤモジュール２０は、長手方向に沿って１列に配置されており、基板２７に搭載されている。なお、複数のＬＥＤモジュール２０が複数列に配置された構成であってもよい。本実施形態においては、複数のＬＥＤモジュール２０の主出射方向は、図２２における図中上方と一致している。なお、主出射方向とは、ＬＥＤモジュール２０から発せられる光の略中心方向を指すものである。主出射方向を中心として、ＬＥＤモジュール２０からの光が広がるように出射される。ただし、主出射方向における輝度が最大である必要はない。 The plurality of LED modules 20 are arranged in a line along the longitudinal direction, and are mounted on the substrate 27. In addition, the structure by which the some LED module 20 was arrange | positioned at multiple rows may be sufficient. In the present embodiment, the main emission direction of the plurality of LED modules 20 coincides with the upper direction in FIG. The main emission direction refers to a substantially central direction of light emitted from the LED module 20.

　図３６は、ＬＥＤモジュール２０の一例を示している。同図のＬＥＤモジュール２０は、ＬＥＤチップ２１、一対のリード２２、ケース２３および透光樹脂２４を具備している。ＬＥＤチップ２１は、たとえばＧａＮ系半導体からなり、たとえば青色光を発する。透光樹脂２４は、ＬＥＤチップ２１を覆っており、たとえば透明樹脂に蛍光材料が混入された材質からなる。この蛍光材料は、ＬＥＤチップ２１からの青色光によって励起されることにより黄色光を発する。この蛍光材料の種類および濃度は、ＬＥＤチップ２１からの青色光とこの蛍光材料からの黄色光とが混色することにより昼白色などの白色を呈するように調整されている。一対のリード２２は、ＬＥＤチップ２１を支持し、かつＬＥＤチップ２１への導通経路となるものであり、たとえばＣｕ合金などからなる。ケース２３は、たとえば白色樹脂からなり、ＬＥＤチップ２１を囲む枠状である。ケース２３の内側面は、ＬＥＤチップ２１からの光を反射することによりこの光を出射させるリフレクタとして機能している。 FIG. 36 shows an example of the LED module 20. The LED module 20 shown in the figure includes an LED chip 21, a pair of leads 22, a case 23, and a translucent resin 24. The LED chip 21 is made of, for example, a GaN-based semiconductor and emits blue light, for example. The translucent resin 24 covers the LED chip 21 and is made of, for example, a material in which a fluorescent material is mixed into a transparent resin. This fluorescent material emits yellow light when excited by blue light from the LED chip 21. The type and concentration of the fluorescent material are adjusted so that a white color such as a neutral white color is obtained by mixing the blue light from the LED chip 21 and the yellow light from the fluorescent material. The pair of leads 22 supports the LED chip 21 and serves as a conduction path to the LED chip 21 and is made of, for example, a Cu alloy. The case 23 is made of white resin, for example, and has a frame shape surrounding the LED chip 21.

　内部先端環状突起５３５は、筒状部５３１の内面において径方向外方から径方向内方に突出し、且つ長手方向内方端に位置する。図２６に示すように、内部先端環状突起５３５は、透光カバー３に当接している。内部先端環状突起５３５は、周方向全周にわたって形成されている。 The inner tip annular projection 535 protrudes from the radially outer side to the radially inner side on the inner surface of the cylindrical portion 531 and is located at the inner end in the longitudinal direction. As shown in FIG. 26, the inner tip annular protrusion 535 is in contact with the translucent cover 3. The inner tip annular projection 535 is formed over the entire circumference.
　複数の内部中間環状突起５３４は、筒状部５３１の内面において径方向外方から径方向内方に突出し、且つ長手方向において内部先端環状突起５３５よりも外方に位置する。図２６に示すように、複数の内部中間環状突起５３４は、透光カバー３に当接している。複数の内部中間環状突起５３４は、周方向全周にわたって形成されている。本実施形態においては、２つの内部中間環状突起５３４が形成されている。２つの内部中間環状突起５３４は、互いに長手方向に離間配置されている。また、２つの内部中間環状突起５３４は、長手方向において、外部係合環状突起５３２とは異なる位置に設けられている。外部係合環状突起５３２は、長手方向において、２つの内部中間環状突起５３４の間に位置している。 The plurality of inner intermediate annular protrusions 534 protrude from the radially outer side to the radially inner side on the inner surface of the cylindrical portion 531 and are positioned outward from the inner tip annular protrusion 535 in the longitudinal direction. As shown in FIG. 26, the plurality of internal intermediate annular protrusions 534 are in contact with the translucent cover 3. The plurality of internal intermediate annular protrusions 534 are formed over the entire circumference in the circumferential direction. In the present embodiment, two internal intermediate annular protrusions 534 are formed. The two inner intermediate annular protrusions 534 are spaced apart from each other in the longitudinal direction. The two inner intermediate annular protrusions 534 are provided at positions different from the outer engagement annular protrusion 532 in the longitudinal direction. The outer engagement annular protrusion 532 is located between the two inner intermediate annular protrusions 534 in the longitudinal direction.
　次に、ＬＥＤ照明灯Ａ２の作用について説明する。 Next, the operation of the LED lighting A2 will be described.
　本実施形態によれば、ＬＥＤ発光部２の基板２７が一対の固定具４の外天板部４２によって支持部材１の天板部１１に対して固定されている。また、一対の固定具４は、支持部材１よりも反射率が高い材質からなる。このため、支持部材１およびＬＥＤ発光部２のみを備える構成と比較して、支持部材１、ＬＥＤ発光部２および固定具４の外観は、より反射率が高い領域が大きい。これにより、ＬＥＤ発光部２からの光のうち透光カバー３の内面によって内方に反射された光を、固定具４によって反射し、透光カバー３を透過させて出射することが可能である。したがって、ＬＥＤ発光部２の基板２７を適切に固定しつつ、ＬＥＤ照明灯Ａ２の高輝度化を図ることができる。 According to this embodiment, the substrate 27 of the LED light emitting unit 2 is fixed to the top plate 11 of the support member 1 by the outer top plate 42 of the pair of fixtures 4. Further, the pair of fixtures 4 are made of a material having a higher reflectance than the support member 1. For this reason, compared with the structure provided only with the support member 1 and the LED light emission part 2, the area | region where a reflectance is higher is large in the external appearance of the support member 1, the LED light emission part 2, and the fixing tool 4. FIG. Thereby, the light reflected inward by the inner surface of the translucent cover 3 out of the light from the LED light emitting unit 2 can be reflected by the fixture 4 and transmitted through the translucent cover 3 to be emitted. . Therefore, it is possible to increase the brightness of the LED illumination lamp A2 while appropriately fixing the substrate 27 of the LED light emitting unit 2.
　固定具４が白色樹脂からなることは、固定具４をより高反射な部材とするのに適している。支持部材１がアルミからなることにより、ＬＥＤ発光部２からの熱を放散することができる。 The fixture 4 made of white resin is suitable for making the fixture 4 a highly reflective member. When the support member 1 is made of aluminum, heat from the LED light emitting unit 2 can be dissipated.
　基板２７に白色のレジスト層２７２が形成されていることにより、ＬＥＤ照明灯Ａ２の高輝度化をさらに促進することができる。固定具４の外天板部４２が基板２７の配線パターン２７１とは重ならない構成とすることにより、外天板部４２によって配線パターン２７１が損傷することを回避することができる。 Since the white resist layer 272 is formed on the substrate 27, it is possible to further promote the increase in brightness of the LED lighting lamp A2. By adopting a configuration in which the outer top plate portion 42 of the fixture 4 does not overlap the wiring pattern 271 of the substrate 27, it is possible to avoid the wiring pattern 271 from being damaged by the outer top plate portion 42.
　第１高反射領域率が、６４％であることにより、配線パターン２７１の損傷を回避しつつ、ＬＥＤ照明灯Ａ２の高輝度化を適切に図ることができる。三方第１高反射領域率が、６９％であることにより、平面視においてのみでなく、ＬＥＤ発光部２からの光が透光カバー３の内面によって反射された後に支持部材１の側方に進行してきた場合であっても、固定具４によって反射する効果が期待できる。さらに、第２高反射領域率が、９５％であることにより、支持部材１、ＬＥＤ発光部２および固定具４の上面に進行してきた光のほとんどを相対的に高い反射率の部位によって透光カバー３へと反射することができる。 When the first high reflection area ratio is 64%, it is possible to appropriately increase the brightness of the LED illumination lamp A2 while avoiding damage to the wiring pattern 271. Since the three-way first high reflection area ratio is 69%, the light from the LED light emitting section 2 travels to the side of the support member 1 after being reflected by the inner surface of the translucent cover 3 as well as in a plan view. Even in this case, the effect of reflection by the fixture 4 can be expected. Further, since the second high reflection area ratio is 95%, most of the light traveling on the upper surfaces of the support member 1, the LED light emitting unit 2, and the fixture 4 is transmitted through the relatively high reflectance portion. It can be reflected to the cover 3.
　図２２および図２３に示すように、下方リブ４３を設けることにより、下方リブ４３と外天板部４２とによって外方リブ１４を図中上下方向に挟む格好となる。これにより、支持部材１に対する固定具４の上下方向位置を規定することができる。また、内側方リブ４６を設けることにより、内側方リブ４６と外側板部４１とによって外方リブ１４を幅方向において挟む格好となる。これにより、支持部材１に対する固定具４の幅方向位置を規定することができる。さらに、外側方リブ４４を設けることにより、外側方リブ４４と内側方リブ４６とによって外方リブ１４を挟む構造となっている。これは、支持部材１に対する固定具４の幅方向位置の精度を高めるのに適している。複数の外側方リブ４４を設けることは、高精度化に有利である。 22 and FIG. 23, by providing the lower rib 43, the outer rib 14 is sandwiched in the vertical direction in the figure by the lower rib 43 and the outer top plate portion 42. Thereby, the up-down direction position of the fixture 4 with respect to the support member 1 can be prescribed | regulated. Further, by providing the inner rib 46, the outer rib 14 is sandwiched in the width direction by the inner rib 46 and the outer plate portion 41. Thereby, the width direction position of the fixture 4 with respect to the support member 1 can be prescribed | regulated. Further, by providing the outer rib 44, the outer rib 14 is sandwiched between the outer rib 44 and the inner rib 46. This is suitable for increasing the accuracy of the position in the width direction of the fixture 4 with respect to the support member 1. Providing the plurality of outer side ribs 44 is advantageous for high accuracy.
　口金５において、本体ケース５１、環状固定具５２および環状パッキン５３が互いに固定されている。環状パッキン５３は、透光カバー３に外嵌されているものの、透光カバー３に対して固定されているものではない。このため、ＬＥＤ照明灯Ａ２の使用環境において温度変化が生じると、透光カバー３は、支持部材１とは熱膨張係数が顕著に異なるため、透光カバー３と支持部材１とは熱変形の度合いが大きく異なる。この差異、支持部材１と本体ケース５１、環状固定具５２および環状パッキン５３とが、長手方向において一体的な挙動を示し、環状パッキン５３は、透光カバー３に対して相対動することとなる。環状パッキン５３は、透光カバー３の長手方向端部から退避した位置にあるため、透光カバー３に対して相対動しても、透光カバー３から外れることなく、透光カバー３内の気密性を保ち続ける。したがって、ＬＥＤ照明灯Ａ２は、温度変化が生じる環境においてより適切に使用することが可能である。 In the base 5, the main body case 51, the annular fixture 52 and the annular packing 53 are fixed to each other. The annular packing 53 is externally fitted to the translucent cover 3, but is not fixed to the translucent cover 3. For this reason, when a temperature change occurs in the usage environment of the LED lighting lamp A2, the translucent cover 3 has a significantly different thermal expansion coefficient from that of the support member 1, and thus the translucent cover 3 and the support member 1 are thermally deformed. The degree varies greatly. Due to this difference, the support member 1, the main body case 51, the annular fixture 52 and the annular packing 53 exhibit an integral behavior in the longitudinal direction, and the annular packing 53 moves relative to the translucent cover 3. . Since the annular packing 53 is in a position retracted from the longitudinal end portion of the translucent cover 3, even if it moves relative to the translucent cover 3, the annular packing 53 does not come off from the translucent cover 3 and does not come out of the translucent cover 3. Keep airtightness. Therefore, the LED lighting A2 can be used more appropriately in an environment where temperature changes occur.
　本体ケース５１および環状固定具５２が、透光カバー３に対して相対動可能である。これにより、透光カバー３の挙動が本体ケース５１および環状固定具５２を介して支持部材１によって拘束されることを回避することができる。 The main body case 51 and the annular fixture 52 are movable relative to the translucent cover 3. Thereby, it is possible to avoid the behavior of the translucent cover 3 being restrained by the support member 1 via the main body case 51 and the annular fixture 52.
　本体ケース５１と透光カバー３とが長手方向において重なる部分を有することにより、温度変化によって伸縮が生じた際に、透光カバー３が本体ケース５１から抜け出てしまうことを防止することができる。 Since the main body case 51 and the translucent cover 3 have a portion overlapping in the longitudinal direction, it is possible to prevent the translucent cover 3 from coming out of the main body case 51 when expansion or contraction occurs due to a temperature change.
　環状固定具５２を係合によって本体ケース５１に固定することにより、組み立てや分解をより容易とすることができる。本体ケース５１の突起５１５と環状固定具５２の係合孔５２１とを設けることは、本体ケース５１と環状固定具５２との係合を実現するのに合理的である。環状固定具５２が複数の個片部５２０からなるため、突起５１５を係合孔５２１に嵌めこむようにして複数の個片部５２０同士を連結することにより、環状固定具５２を本体ケース５１に対して適切に取り付けることができる。 The assembly and disassembly can be made easier by fixing the annular fixture 52 to the main body case 51 by engagement. Providing the protrusion 515 of the main body case 51 and the engagement hole 521 of the annular fixture 52 is reasonable for realizing the engagement between the main body case 51 and the annular fixture 52. Since the annular fixture 52 is composed of a plurality of pieces 520, the annular fixture 52 is connected to the main body case 51 by connecting the pieces 520 to each other so that the projection 515 is fitted in the engagement hole 521. Can be installed properly.
　環状パッキン５３を係合によって環状固定具５２に固定することにより、組み立てや分解をより容易とすることができる。環状パッキン５３の外部係合環状突起５３２と環状固定具５２の環状溝５２２とを設けることは、環状固定具５２と環状パッキン５３との係合を実現するのに合理的である。 By fixing the annular packing 53 to the annular fixture 52 by engagement, assembly and disassembly can be facilitated. Providing the outer engaging annular protrusion 532 of the annular packing 53 and the annular groove 522 of the annular fixing member 52 is rational for realizing the engagement between the annular fixing member 52 and the annular packing 53.
　環状パッキン５３が外部先端環状突起５３３を有することにより、温度変化、特に常温からより高温となる変化が生じた場合に、相対的に伸長する透光カバー３に伴って、環状パッキン５３が環状固定具５２の内側に入り込んでしまうことを阻止することができる。 Since the annular packing 53 has the outer tip annular projection 533, the annular packing 53 is annularly fixed along with the light-transmitting cover 3 that relatively expands when a temperature change, particularly a change from room temperature to a higher temperature occurs. It can prevent entering the inside of the tool 52.
　内部中間環状突起５３４を設けることにより、環状パッキン５３と透光カバー３との接触面積を減少させることができる。環状パッキン５３がゴムなどの柔軟性に富む材質からなる場合、接触面積の現象により、摩擦力を低減させることが可能である。これにより、透光カバー３に対して環状パッキン５３をよりスムーズに相対動させることができる。複数の内部中間環状突起５３４を設けることにより、摩擦力の低減と環状パッキン５３を透光カバー３に安定して外嵌させることとを両立することができる。 By providing the inner intermediate annular protrusion 534, the contact area between the annular packing 53 and the translucent cover 3 can be reduced. When the annular packing 53 is made of a flexible material such as rubber, the frictional force can be reduced due to the phenomenon of the contact area. Thereby, the annular packing 53 can be moved relatively smoothly with respect to the translucent cover 3. By providing the plurality of internal intermediate annular protrusions 534, it is possible to achieve both reduction of frictional force and stable outer fitting of the annular packing 53 to the translucent cover 3.
　内部先端環状突起５３５を設けることにより、環状パッキン５３の長手方向内方、すなわち環状パッキン５３と外部との境界において、気密性をより確実に確保することができる。 By providing the inner tip annular protrusion 535, the airtightness can be more reliably ensured at the inner side in the longitudinal direction of the annular packing 53, that is, at the boundary between the annular packing 53 and the outside.
　ねじ５９を支持部材１の筒状部１３に螺合させることにより、支持部材１と本体ケース５１とをより確実に固定させることができる。一対の筒状部１３は、支持部材１の長手方向全長にわたって形成されており、透光カバー３の一対の内方リブ３２と係合している。これにより、支持部材１に対して透光カバー３が周方向にずれてしまうことを阻止することができる。 By screwing the screw 59 into the cylindrical portion 13 of the support member 1, the support member 1 and the main body case 51 can be more reliably fixed. The pair of cylindrical portions 13 are formed over the entire length in the longitudinal direction of the support member 1 and are engaged with the pair of inward ribs 32 of the translucent cover 3. Thereby, it can prevent that the translucent cover 3 slip | deviates with respect to the supporting member 1 in the circumferential direction.
　一対の固定具４によってＬＥＤ発光部２の基板２７を支持部材１に対して固定することにより、比較的長尺の基板２７であっても、長手方向全長にわたって支持部材１に沿わせることができる。 By fixing the substrate 27 of the LED light emitting unit 2 to the support member 1 with the pair of fixtures 4, even the relatively long substrate 27 can be fitted along the support member 1 over the entire length in the longitudinal direction. .
　図３７および図３８は、本発明の他の実施形態を示している。なお、これらの図において、上記実施形態と同一または類似の要素には、上記実施形態と同一の符号を付している。 37 and 38 show another embodiment of the present invention. In these drawings, the same or similar elements as those in the above embodiment are denoted by the same reference numerals as those in the above embodiment.
　図３７は、本発明の第３実施形態に基づくＬＥＤ照明灯を示している。本実施形態のＬＥＤ照明灯Ａ３は、一対の固定具４とＬＥＤ発光部２の基板２７との関係が、上述した実施形態と異なっている。本実施形態においては、一対の固定具４の外天板部４２は、平面視において、レジスト層２７２に重なるとともに、配線パターン２７１にも重なっている。また、同図によく表れているように、一対の固定具４の外天板部４２の幅方向内端縁は、複数のＬＥＤモジュール２０に隣接する位置に配置されている。 FIG. 37 shows an LED illuminating lamp according to the third embodiment of the present invention. The LED illuminating lamp A3 of this embodiment is different from the above-described embodiment in the relationship between the pair of fixtures 4 and the substrate 27 of the LED light emitting unit 2. In the present embodiment, the outer top plate portion 42 of the pair of fixtures 4 overlaps the resist layer 272 and also the wiring pattern 271 in plan view. Further, as clearly shown in the figure, the inner edge in the width direction of the outer top plate portion 42 of the pair of fixtures 4 is disposed at a position adjacent to the plurality of LED modules 20.
　このような構成により、本実施形態においては、第１高反射領域率が、８０％とされている。また、三方第１高反射領域率は、７９％となっている。第２高反射領域率は、ＬＥＤ照明灯Ａ２と同様に９５％程度である。 With such a configuration, in the present embodiment, the first high reflection area ratio is 80%. The three-way first high reflection area ratio is 79%. The second high reflection area ratio is about 95%, similar to the LED illumination lamp A2.
　このような実施形態によれば、ＬＥＤ照明灯Ａ３の高輝度化をさらに高めることができる。また、ＬＥＤ照明灯Ａ２およびＬＥＤ照明灯Ａ３から理解できるように、第１高反射領域率の下限は、外天板部４２を配線パターン２７１とは重ならない構成とした場合であり、上限は、外天板部４２がＬＥＤモジュール２０に隣接する構成とした場合である。したがって、第１高反射領域率は、６４％以上８０％以下であることが好ましい。同様に、三方第２高反射領域率は、６９％以上７９％以下であることが好ましい。また、第２高反射領域率は、９０％以上９５％以下であることが好ましい。 According to such an embodiment, it is possible to further increase the brightness of the LED lighting A3. Moreover, as can be understood from the LED lighting lamp A2 and the LED lighting lamp A3, the lower limit of the first high reflection area ratio is a case where the outer top plate portion 42 is configured not to overlap the wiring pattern 271. This is a case where the outer top plate portion 42 is configured to be adjacent to the LED module 20. Therefore, the first high reflection area ratio is preferably 64% or more and 80% or less. Similarly, the three-way second high reflection area ratio is preferably 69% or more and 79% or less. The second high reflection area ratio is preferably 90% or more and 95% or less.
　図３８は、本発明の第４実施形態に基づくＬＥＤ照明灯を示している。本実施形態のＬＥＤ照明灯Ａ４は、口金５の構成が上述した実施形態と異なっている。本実施形態の口金５は、本体ケース５１および端子５５を有している。本体ケース５１は、たとえば樹脂からなる有底円筒形状の部材である。端子５５には溝部５６が設けられている。溝部５６には、透光カバー３が挿入されている。端子５５は、電源ケーブル８１によって、ＬＥＤ発光部２に電力供給するための電源部５に接続されている。電源部５と基板２７とは、ＬＥＤケーブル２９によって接続されている。このような実施形態によっても、ＬＥＤ発光部２の基板２７を適切に固定しつつ、ＬＥＤ照明灯Ａ４の高輝度化を図ることができる。 FIG. 38 shows an LED illuminating lamp according to the fourth embodiment of the present invention. The LED illumination lamp A4 of the present embodiment is different from the above-described embodiment in the configuration of the base 5. The base 5 of this embodiment has a main body case 51 and a terminal 55. The main body case 51 is a bottomed cylindrical member made of resin, for example. The terminal 55 is provided with a groove 56. The translucent cover 3 is inserted into the groove portion 56. The terminal 55 is connected to the power source unit 5 for supplying power to the LED light emitting unit 2 by a power cable 81. The power supply unit 5 and the substrate 27 are connected by an LED cable 29. Even in such an embodiment, it is possible to increase the brightness of the LED illumination lamp A4 while appropriately fixing the substrate 27 of the LED light emitting unit 2.
　本発明に係るＬＥＤ照明灯は、上述した実施形態に限定されるものではない。本発明に係るＬＥＤ照明灯の各部の具体的な構成は、種々に設計変更自在である。 The LED illumination lamp according to the present invention is not limited to the above-described embodiment. The specific configuration of each part of the LED illumination lamp according to the present invention can be varied in design in various ways.
