 図1は、本実施形態に係るLEDランプ1を用いた照明器具5の構成を示す図である。なお、以下の説明において、LEDランプ1の表裏とは、光源からの光の放射方向を表として定義するものでる。また、LEDランプ1の上下とは、後述する口金40の軸方向において口金40側を下として定義するものである。なお、本実施形態において、口金40の軸方向とは、口金40をねじ込み式(回しこみ式)のものとした場合に、口金40の回転軸に沿った方向のことである。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating a configuration of a lighting fixture 5 using an LED lamp 1 according to the present embodiment. In addition, in the following description, the front and back of the LED lamp 1 defines the radiation direction of light from the light source as a table. Moreover, the upper and lower sides of the LED lamp 1 are defined with the base 40 side as the lower side in the axial direction of the base 40 described later. In the present embodiment, the axial direction of the base 40 is a direction along the rotation axis of the base 40 when the base 40 is a screw-type (rotating type).
 LEDランプ1は、図1に示すように、器具本体100に取り付けられて使用されるランプである。LEDランプ1は、HIDランプのような高出力タイプの既存の放電ランプの代わりに用いることができる程度の光出力を有する。また、LEDランプ1は、放電ランプが従来取り付けられていた既存の器具本体100を置き換えることなく、器具本体100に取り付けることができる。また、LEDランプ1は、口金40を備えた口金型のランプであり、口金40を器具本体100の既設のソケット105に装着して使用できる。照明器具5には、光の放射方向に本体グローブ110が着脱可能に取り付けられる。LEDランプ1は、本体グローブ110を取り外した開口部から器具本体100のソケット105に口金40を螺入させて取り付けられる。 The LED lamp 1 is a lamp that is attached to the instrument body 100 and used as shown in FIG. The LED lamp 1 has a light output that can be used in place of a high-power type existing discharge lamp such as an HID lamp. Moreover, the LED lamp 1 can be attached to the instrument main body 100 without replacing the existing instrument main body 100 to which the discharge lamp has been conventionally attached. The LED lamp 1 is a die-type lamp having a base 40, and can be used by attaching the base 40 to an existing socket 105 of the instrument body 100. The main body globe 110 is detachably attached to the lighting fixture 5 in the light emission direction. The LED lamp 1 is attached by screwing the base 40 into the socket 105 of the instrument main body 100 from the opening from which the main body globe 110 is removed.
 ただし、放電ランプは交流電力で点灯するが、LEDなどの発光素子は直流電力で点灯する。したがって、発光素子の一例たるLED11を光源としたLEDランプ1を交流の商用電源で点灯させる場合には、商用電源を直流電力に変換する電源回路を通じてLEDランプ1に直流電力を供給することとなる。本実施形態のLEDランプ1は電源回路を内蔵せずに、ソケット105の側に電源回路を設け、当該ソケット105から口金40を通じて直流電力が入力される構成となっている。換言すれば、このLEDランプ1を既設の放電ランプ用の灯具に装着する場合には、灯具が備える安定器を電源回路に置き換えて使用する。
 本実施形態のLEDランプ1は、例えば100W~300Wの水銀ランプを用いた防犯灯などで、水銀ランプの代替として用いることができるランプである。また、LEDランプ1は、口金40を含む全長が略15cm~30cmのランプである。
However, while the discharge lamp is lit with AC power, the light emitting elements such as LEDs are lit with DC power. Therefore, when the LED lamp 1 using the LED 11 as an example of the light emitting element as a light source is lit with an AC commercial power source, DC power is supplied to the LED lamp 1 through a power supply circuit that converts the commercial power source into DC power. . The LED lamp 1 of the present embodiment has a configuration in which a power supply circuit is provided on the socket 105 side without incorporating a power supply circuit, and DC power is input from the socket 105 through the base 40. In other words, when the LED lamp 1 is mounted on an existing lamp for a discharge lamp, the ballast included in the lamp is replaced with a power supply circuit.
The LED lamp 1 of the present embodiment is a crime prevention lamp using a mercury lamp of 100 W to 300 W, for example, and can be used as an alternative to the mercury lamp. The LED lamp 1 is a lamp having a total length including the base 40 of approximately 15 cm to 30 cm.
 次いで、LEDランプ1の構成について詳述する。
 LEDランプ1は、図2、図3に示すように、光源を備えた光源ユニット10(光源部)と、光源ユニット10を保持する光源保持ユニット30(光源保持部)と、を備える。光源保持ユニット30は、口金40を有し、この口金40の中心軸Oに沿って柱状に延びる。口金40は、例えばE26タイプやE39タイプ等の一般的にE型口金と呼ばれるねじ込み式(回しこみ式)のものであり、既存のサイズに合わせて構成され、既設のソケット105に螺入させて装着可能になっている。なお、口金40の中心軸Oとは、口金40をソケット105に螺入させる際の回転軸である。口金40には、ソケット105を通じて直流電源が供給され、光源ユニット10に供給される。なお、口金40には差し込み式を用いても良い。
Next, the configuration of the LED lamp 1 will be described in detail.
As shown in FIGS. 2 and 3, the LED lamp 1 includes a light source unit 10 (light source unit) including a light source, and a light source holding unit 30 (light source holding unit) that holds the light source unit 10. The light source holding unit 30 has a base 40 and extends in a column shape along the central axis O of the base 40. The base 40 is, for example, a screw type (rotating type) generally called an E type base such as E26 type or E39 type, and is configured according to the existing size and screwed into an existing socket 105. It can be installed. The central axis O of the base 40 is a rotation axis when the base 40 is screwed into the socket 105. A direct current power is supplied to the base 40 through the socket 105 and supplied to the light source unit 10. The base 40 may be a plug-in type.
 光源ユニット10は、発光素子の一例たるLED11を光源として備える光源モジュール20と、光源モジュール20が表面に配置される矩形平板状の基台16と、を備える。光源ユニット10は、2つの基台16を備え、これら2つの基台16が、V字状に連結されて灯具本体15を構成する。2つの基台16は、互いのなす角度αが45°~135°となるようにV字状に連結される。2つの基台16の互いのなす角度αは、器具本体100の形状や、照明器具5の規定の配光に応じて適宜に設定することができる。本実施形態のLEDランプ1は、2つの基台16のなす角度αが、略90°に設定されている。また、口金40は、中心軸Oが、V字状に連結された2つの基台16の間で、鋭角側に形成されるエリアB(図4参照)の内側に位置するように配置される。つまり、口金40の中心軸Oは、各基台16の外端16Aを結ぶ線よりも、2つの基台16の連結部25側に位置する。 The light source unit 10 includes a light source module 20 including an LED 11 as an example of a light emitting element as a light source, and a rectangular flat base 16 on which the light source module 20 is disposed. The light source unit 10 includes two bases 16, and the two bases 16 are connected in a V shape to form a lamp body 15. The two bases 16 are connected in a V shape so that the angle α between them is 45 ° to 135 °. The angle α between the two bases 16 can be appropriately set according to the shape of the fixture body 100 and the prescribed light distribution of the lighting fixture 5. In the LED lamp 1 of the present embodiment, the angle α formed by the two bases 16 is set to approximately 90 °. The base 40 is arranged so that the central axis O is located inside the area B (see FIG. 4) formed on the acute angle side between the two bases 16 connected in a V shape. . That is, the central axis O of the base 40 is positioned closer to the connecting portion 25 side of the two bases 16 than the line connecting the outer ends 16A of the bases 16.
 基台16の裏面には、複数枚の板状の冷却フィン17が配置される。各冷却フィン17は、基台16の外端16Aから、基台16の短手方向に亘って延びる。冷却フィン17は、基台16の表面に配置された光源モジュール20から基台16に伝熱されたLED11の熱を吸熱して放熱することで、LED11を冷却する。灯具本体15は、2つの基台16及び冷却フィン17が、例えばアルミニウム等の高熱伝導性を有する金属材から一体成形される。灯具本体15は、鋳造(例えばアルミダイキャスト)により成形されるのが望ましい。 A plurality of plate-like cooling fins 17 are arranged on the back surface of the base 16. Each cooling fin 17 extends from the outer end 16 </ b> A of the base 16 in the short direction of the base 16. The cooling fins 17 absorb the heat of the LEDs 11 transferred from the light source module 20 disposed on the surface of the base 16 to the base 16 and dissipate the heat, thereby cooling the LEDs 11. In the lamp body 15, the two bases 16 and the cooling fins 17 are integrally formed from a metal material having high thermal conductivity such as aluminum. The lamp body 15 is preferably formed by casting (for example, aluminum die casting).
 光源モジュール20は、実装基板12と、実装基板12の表面に実装された複数のLED11と、から構成される。光源モジュール20は、口金40の軸方向に沿って延びる矩形状のモジュールである。本実施形態のLEDランプ1では、2つの光源モジュール20を備え、これらの光源モジュール20が、口金40の軸方向に延びる姿勢で配列され、V字状に連結された基台16のそれぞれに支持されている。LEDランプ1は、各基台16に配置された光源モジュール20からの光により所望の得られるように構成される。なお、図示は省略するが、器具本体100の内側に、反射鏡などの光学部材を設けて、LEDランプ1からの光により所望の配光を得る構成であっても良い。 The light source module 20 includes a mounting substrate 12 and a plurality of LEDs 11 mounted on the surface of the mounting substrate 12. The light source module 20 is a rectangular module extending along the axial direction of the base 40. The LED lamp 1 according to the present embodiment includes two light source modules 20, and these light source modules 20 are arranged in a posture extending in the axial direction of the base 40 and supported on each of bases 16 connected in a V shape. Has been. The LED lamp 1 is configured to be obtained as desired by light from the light source module 20 disposed on each base 16. In addition, although illustration is abbreviate | omitted, the structure which provides optical members, such as a reflecting mirror, inside the instrument main body 100, and obtains desired light distribution with the light from the LED lamp 1 may be sufficient.
 実装基板12は、略矩形板状のプリント配線基板であって、その表面には、充電部を構成する電極パターン19が設けられる。電極パターン19は、実装基板12の下端部に形成され、図示を省略したプリント配線を通じて各LED11に直列又は並列に電気的に接続されている。実装基板12は、電気絶縁部材21(図6参照)を挟んで基台16の表面に取り付けられる。なお、本実施形態の光源モジュール20は、実装基板12の表面に複数のLED11を実装する構成であるが、これに限らず、多数のLED素子を配列してその表面を樹脂材でモールドして成る所謂COB型LEDを光源として備え、実装基板12の略全面が発光する構成であっても良い。 The mounting board 12 is a substantially rectangular printed wiring board, and an electrode pattern 19 constituting a charging unit is provided on the surface thereof. The electrode pattern 19 is formed at the lower end of the mounting substrate 12 and is electrically connected in series or in parallel to each LED 11 through a printed wiring (not shown). The mounting substrate 12 is attached to the surface of the base 16 with the electrical insulating member 21 (see FIG. 6) interposed therebetween. The light source module 20 of the present embodiment has a configuration in which a plurality of LEDs 11 are mounted on the surface of the mounting substrate 12. However, the present invention is not limited to this, and a number of LED elements are arranged and the surface is molded with a resin material. Such a so-called COB type LED may be provided as a light source, and a substantially entire surface of the mounting substrate 12 may emit light.
 また、各基台16には、光源モジュール20を覆うグローブ13(カバー)が配置される。グローブ13は、透光性のある材料、例えば樹脂材を用いて、平面視矩形状、かつ、断面半楕円形状に形成される。グローブ13は、基台16に対向する、長手方向の両辺が凹状に切り欠かれ、グローブ13と、基台16との間には、隙間18が形成される。この構成によれば、グローブ13と、基台16との間に隙間18を形成したため、グローブ13の内側にLED11の熱が篭もるのを防ぐことができる。また、光源モジュール20をグローブ13で覆ったため、LEDランプを取り扱う際に、LED11に作業者の手等が直接触れるのを防止することができる。 Further, a globe 13 (cover) covering the light source module 20 is disposed on each base 16. The globe 13 is formed in a rectangular shape in plan view and a semi-elliptical cross section using a translucent material such as a resin material. The globe 13 is notched in a concave shape on both sides in the longitudinal direction facing the base 16, and a gap 18 is formed between the globe 13 and the base 16. According to this configuration, since the gap 18 is formed between the globe 13 and the base 16, the heat of the LED 11 can be prevented from being trapped inside the globe 13. Further, since the light source module 20 is covered with the globe 13, it is possible to prevent the operator's hand or the like from directly touching the LED 11 when handling the LED lamp.
 図4は、LEDランプ1の構成を示す図である。LEDランプ1は、上面視図において、図4に示すように、破線で示した直径Rの仮想円Xの内側に、基台16の外端16A、及び、冷却フィン17が収まるように構成されている。この仮想円Xは、器具本体100の内側に内接する円よりも小さな直径の円であり、仮想円Xの中心は、口金40の中心軸Oと一致させている。LEDランプ1は、この仮想円Xに基台16の外端16A、及び、冷却フィン17が収まるように設計される。これにより、LEDランプ1は、器具本体100のソケット105に口金40を螺入する際に、光源ユニット10が器具本体100と干渉しないように構成される。また、基台16の外端16Aは、仮想円XにLEDランプ1が内接する位置まで延出される。これにより、基台16の外端16A、及び、冷却フィン17を、器具本体100のソケットに口金40を螺入する際に、器具本体100と干渉しない位置までできる限り延出させることができる。これらの構成によれば、光源ユニット10が器具本体100に干渉することなく、器具本体100のソケットに口金40を螺入することができ、かつ、LED11を搭載できる面積、及び、冷却フィン17の放熱面積をできるだけ大きくすることができる。よって、LEDランプ1を、既存の器具本体100に容易に取り付けることができ、コンパクトでかつ高出力な構成とすることができる。なお、本実施形態のLEDランプ1は、仮想円の直径Rが略280mmに設定されている。 FIG. 4 is a diagram showing the configuration of the LED lamp 1. As shown in FIG. 4, the LED lamp 1 is configured so that the outer end 16 </ b> A of the base 16 and the cooling fins 17 are accommodated inside a virtual circle X having a diameter R indicated by a broken line in a top view. ing. The virtual circle X is a circle having a smaller diameter than the circle inscribed inside the instrument main body 100, and the center of the virtual circle X coincides with the central axis O of the base 40. The LED lamp 1 is designed so that the outer end 16 </ b> A of the base 16 and the cooling fins 17 are accommodated in the virtual circle X. Thus, the LED lamp 1 is configured such that the light source unit 10 does not interfere with the instrument body 100 when the base 40 is screwed into the socket 105 of the instrument body 100. Further, the outer end 16 </ b> A of the base 16 extends to a position where the LED lamp 1 is inscribed in the virtual circle X. Accordingly, the outer end 16 </ b> A of the base 16 and the cooling fin 17 can be extended as much as possible to a position that does not interfere with the instrument body 100 when the base 40 is screwed into the socket of the instrument body 100. According to these configurations, the light source unit 10 can be screwed into the socket of the instrument main body 100 without interfering with the instrument main body 100, and the area where the LED 11 can be mounted, and the cooling fins 17. The heat dissipation area can be made as large as possible. Therefore, the LED lamp 1 can be easily attached to the existing apparatus main body 100, and it can be set as a compact and high output structure. In the LED lamp 1 of the present embodiment, the diameter R of the virtual circle is set to about 280 mm.
 次に、冷却フィン17の構成について説明する。
 冷却フィン17は、図3(B)に示すように、2つの基台16の連結部25の裏面に形成された溝部25Aから、基台16の外端16Aに向かって、口金40の中心軸Oに対して傾斜する。本実施形態では、冷却フィン17は、溝部25Aから、基台16の外端16Aに向かって、斜め下向きに、つまり口金40側に向かって、傾斜する。口金40の中心軸Oに対する冷却フィン17の傾斜角度βは略45°~80°であることが望ましい。また、各基台16の裏面から延びる冷却フィン17は、溝部25Aにおいて、中心軸Oを中心に互いに離隔し、隙間G(図4参照)が形成される。隙間Gにより、各冷却フィン17間の空間の空気が流通し易くなるため、冷却フィン17からの放熱性を高めることができる。また、冷却フィン17を、溝部25Aから、基台16の外端16Aに向かって、口金40の中心軸Oに対して傾斜する構成としたため、冷却フィン17間の空間の空気を傾斜方向に沿って流すことができ、所望の方向に空気を導くことができる。
Next, the configuration of the cooling fin 17 will be described.
As shown in FIG. 3B, the cooling fin 17 has a central axis of the base 40 from the groove portion 25 </ b> A formed on the back surface of the connecting portion 25 of the two bases 16 toward the outer end 16 </ b> A of the base 16. Inclined with respect to O. In the present embodiment, the cooling fin 17 is inclined obliquely downward from the groove portion 25 </ b> A toward the outer end 16 </ b> A of the base 16, that is, toward the base 40 side. The inclination angle β of the cooling fin 17 with respect to the central axis O of the base 40 is preferably about 45 ° to 80 °. Further, the cooling fins 17 extending from the back surface of each base 16 are separated from each other about the central axis O in the groove 25A, and a gap G (see FIG. 4) is formed. Since the air in the space between the cooling fins 17 easily flows due to the gap G, the heat dissipation from the cooling fins 17 can be enhanced. Further, since the cooling fin 17 is configured to be inclined with respect to the central axis O of the base 40 from the groove 25A toward the outer end 16A of the base 16, the air in the space between the cooling fins 17 is along the inclination direction. The air can be guided in a desired direction.
 また、冷却フィン17は、図5(B)に示すように、基台16の裏面に対して傾斜する。冷却フィン17の基台16の裏面に対する傾斜角度γは略60°~80°であることが望ましい。このように、冷却フィン17を基台16の裏面に対して傾斜させることで、冷却フィン17間の空間の空気を傾斜方向に沿って流すことができ、所望の方向に空気を導いて、冷却フィン17からの放熱性を高めることができる。 Further, the cooling fins 17 are inclined with respect to the back surface of the base 16 as shown in FIG. The inclination angle γ of the cooling fin 17 with respect to the back surface of the base 16 is preferably approximately 60 ° to 80 °. In this way, by inclining the cooling fins 17 with respect to the back surface of the base 16, the air in the space between the cooling fins 17 can flow along the inclination direction, and the air is guided in a desired direction for cooling. The heat dissipation from the fin 17 can be improved.
 また、冷却フィン17は、基台16の外端16A側の外端部17Aが、溝部25A側の内端部17Bよりも厚く形成されている。この構成によれば、連結された2つの基台16において、互いの遠部で多くの熱を吸熱することができる。よって、一方の基台16に配置された光源モジュール20の熱が、他方の基台16に流れるのを防いで、各基台16で光源モジュール20の熱を効率よく放熱させることができる。 Further, the cooling fin 17 is formed such that the outer end 17A on the outer end 16A side of the base 16 is thicker than the inner end 17B on the groove 25A side. According to this configuration, in the two connected bases 16, a large amount of heat can be absorbed at the far part of each other. Therefore, the heat of the light source module 20 arranged on one base 16 is prevented from flowing to the other base 16, and the heat of the light source module 20 can be efficiently radiated by each base 16.
 LEDランプ1は、器具本体100に取り付けられた状態で、LEDランプ1の上端と器具本体100との間に空間Aが生じる(図1(D)参照)。この空間Aは、LEDランプ1を、口金40をソケット105に螺入させて器具本体100に固定する際に必要な空間である。上述したように、本実施形態のLEDランプ1は、冷却フィン17が、溝部25Aから、基台16の外端16Aに向かって、口金40の中心軸Oに対して斜め下向きに傾斜するとともに、基台16の裏面に対して斜め上向きに傾斜する。この構成よれば、LEDランプ1の上側の空間Aに冷却フィン17間の空間の空気を導くことができ、冷却フィン17からの放熱性を高め、LED11を効率よく冷却することができる。 When the LED lamp 1 is attached to the instrument body 100, a space A is created between the upper end of the LED lamp 1 and the instrument body 100 (see FIG. 1D). This space A is a space required when the LED lamp 1 is fixed to the instrument main body 100 by screwing the base 40 into the socket 105. As described above, in the LED lamp 1 of the present embodiment, the cooling fin 17 is inclined obliquely downward with respect to the central axis O of the base 40 toward the outer end 16A of the base 16 from the groove portion 25A. It is inclined obliquely upward with respect to the back surface of the base 16. According to this configuration, the air in the space between the cooling fins 17 can be guided to the space A above the LED lamp 1, the heat dissipation from the cooling fins 17 can be improved, and the LED 11 can be efficiently cooled.
 また、冷却フィン17は、上述のように、溝部25Aから、基台16の外端16Aに向かって、口金40の中心軸Oに対して傾斜するとともに、基台16の裏面に対して傾斜し、かつ、図3(B)に示すように、LEDランプ1の背面視で垂直方向に延びている。この構成によれば、冷却フィン17を、基台16と一体に鋳造により成形する際に、型の抜きを容易に行うことができる。 Further, as described above, the cooling fin 17 is inclined with respect to the central axis O of the base 40 toward the outer end 16 </ b> A of the base 16 from the groove portion 25 </ b> A and with respect to the back surface of the base 16. As shown in FIG. 3B, the LED lamp 1 extends in the vertical direction when viewed from the back. According to this configuration, when the cooling fin 17 is molded integrally with the base 16 by casting, the mold can be easily removed.
 図6は、LEDランプ1の分解斜視図である。図6に示すように、基台16は、実装基板12を内部に収容可能な表面積を有する大きさの薄板状に形成される。基台16の表面には、電気絶縁部材21、及び、実装基板12を収容する収容部22が設けられる。収容部22は、実装基板12を基台16と略面一に収める深さの凹部であり、底面が平面状に形成される。電気絶縁部材21及び光源モジュール20は、収容部22の底面にねじ止めされる。グローブ13には、膨出部13Aが形成され、基台16との間に形成される隙間からリード線24を取り出すことができる。グローブ13は、上下端部の短手方向の略中央がそれぞれ基台16の表面にねじ止めされる。 FIG. 6 is an exploded perspective view of the LED lamp 1. As shown in FIG. 6, the base 16 is formed in a thin plate shape having a surface area that can accommodate the mounting substrate 12 therein. On the surface of the base 16, an electrical insulating member 21 and an accommodating portion 22 that accommodates the mounting substrate 12 are provided. The accommodating portion 22 is a recess having a depth that allows the mounting substrate 12 to be substantially flush with the base 16, and the bottom surface is formed in a planar shape. The electrical insulating member 21 and the light source module 20 are screwed to the bottom surface of the housing portion 22. The globe 13 is formed with a bulging portion 13 </ b> A, and the lead wire 24 can be taken out from a gap formed between the globe 13 and the base 16. The globe 13 is screwed to the surface of the base 16 at approximately the center in the short direction of the upper and lower ends.
 実装基板12の下端部に形成された電極パターン19には、実装基板12の裏面にリード線24が、例えば半田付けされて接続される。基台16の下端には、リード線24を基台16の裏面に配線する配線孔23が設けられる。配線孔23は、本実施形態では、基台16の下端の一部を切り欠いて形成されるが、基台16の下端部に設けられた貫通孔であっても良い。また、図示は省略するが、基台16の表面には、収容部22から配線孔23につながる凹部が設けられ、この凹部を通してリード線24を収容部22から配線孔23に配線しても良い。各実装基板12から延びるリード線24の先端には、それぞれ雄コネクタ26Aが取り付けられる。 A lead wire 24 is connected to the electrode pattern 19 formed on the lower end portion of the mounting substrate 12 by soldering, for example, to the back surface of the mounting substrate 12. A wiring hole 23 for wiring the lead wire 24 to the back surface of the base 16 is provided at the lower end of the base 16. In the present embodiment, the wiring hole 23 is formed by cutting out a part of the lower end of the base 16, but may be a through hole provided in the lower end of the base 16. Although not shown in the drawings, a concave portion connected from the housing portion 22 to the wiring hole 23 is provided on the surface of the base 16, and the lead wire 24 may be wired from the housing portion 22 to the wiring hole 23 through the concave portion. . Male connectors 26A are attached to the tips of the lead wires 24 extending from the mounting boards 12, respectively.
 次に、光源保持ユニット30の構成について説明する。
 光源保持ユニット30は、口金40と、口金受体31と、回路基板32と、回転ユニット42と、を備える。
 口金受体31には、下側から口金40が冠着される。口金受体31は、ポリカーボネート樹脂等の樹脂材により、中空部を有する円柱状に形成される。口金受体31の中空内部には、回路基板32が収容される。回路基板32には、雌コネクタ26Bが配置される。回路基板32が収容された口金受体31の内部の中空部は、下面に至って開口し、連通路43として構成されている。実装基板12から延びるリード線24の雄コネクタ26Aは、後述する回転ユニット42の導入孔37A,37Bを通して、雌コネクタ26Bに接続される。リード線24は、雌コネクタ26Bが設置された回路基板32のパターン上でまとめられて、結線され、連通路43を通して、口金40に延び、口金40に接続される。これにより、各光源モジュール20と口金40とがリード線24、24により電気的に接続され、口金40を通じて供給される直流電力によって各光源モジュール20に配置されたLED11が点灯する。
Next, the configuration of the light source holding unit 30 will be described.
The light source holding unit 30 includes a base 40, a base receiver 31, a circuit board 32, and a rotation unit 42.
A base 40 is attached to the base receiver 31 from below. The base receiver 31 is formed in a cylindrical shape having a hollow portion by a resin material such as polycarbonate resin.

 また、上述したように、雄回転アダプタ33と、雌回転アダプタ34とには、それぞれ雄側ストッパー38A、雌側ストッパー38Bが設けられている。雄回転アダプタ33と、雌回転アダプタ34と、の相対的な回転は、雄側ストッパー38Aと、雌側ストッパー38Bと、が干渉することで、360°以上回転しないように規制される。
As shown in FIG. 7D, the male rotation adapter 33 and the female rotation adapter 34 can be relatively rotated by releasing the meshing of the protrusions 41A and 41B by manually pulling them apart in the axial direction. Become. At this time, the spring 35 accommodated in the female rotation adapter 34 is further pressed between the presser fitting 36 and the bottom plate 34 </ b> A of the female rotation adapter 34. The male rotation adapter 33 and the female rotation adapter 34 are released from the force of pulling them apart in the axial direction, so that a force that pushes them relatively in the axial direction by the spring 35 is applied, and the protrusions 41A and 41B are engaged.
As described above, the male rotation adapter 33 and the female rotation adapter 34 are provided with the male side stopper 38A and the female side stopper 38B, respectively. The relative rotation between the male rotation adapter 33 and the female rotation adapter 34 is regulated so that it does not rotate 360 ° or more because the male side stopper 38A and the female side stopper 38B interfere with each other.
 雄回転アダプタ33は、口金受体31の下側から、膨出部33Cに設けられたねじ穴にねじ込まれたねじで回路基板32と共に口金受体31にねじ止めされる。回路基板32の上面に突設された雌コネクタ26Bは、雄回転アダプタ33の台座部33Aの底部に設けられた凹み部45内に収容される。

 図7および図8に示すように、LEDランプ1は、雌回転アダプタ34に設けられたフランジ39を、灯具本体15の下面にねじ止めして、光源保持ユニット30と、光源ユニット10とが一体に構成される。フランジ39は、各基台16、及び、2つの基台16の連結部25に対応する位置に設けられ、各基台16の下面と、連結部25の下面とに、ねじ止めされる。 As shown in FIGS. 7 and 8, the LED lamp 1 has the light source holding unit 30 and the light source unit 10 integrally formed by screwing a flange 39 provided on the female rotation adapter 34 to the lower surface of the lamp body 15. Configured. The flange 39 is provided at a position corresponding to each base 16 and the connecting portion 25 of the two bases 16, and is screwed to the lower surface of each base 16 and the lower surface of the connecting portion 25.
 LEDランプ1は、光源モジュール20が、V字状に連結された基台16の表面に配置されているため、口金40を器具本体100のソケット105に螺入させて、LEDランプ1を器具本体100に対して固定した際に、LEDランプ1の照射方向が、照明器具5の照射方向と一致しない場合がある。LEDランプ1の照射方向が、照明器具5の照射方向と一致しない場合には、LEDランプ1の口金40を器具本体100のソケット105に螺入した状態で、光源ユニット10を、口金40の軸方向に、口金40から引き離すように引く。これにより、図8(A)及び図8(B)に示すように、雄回転アダプタ33と、雌回転アダプタ34との、突起41A、41Bの噛み合いが解除され、光源ユニット10が、光源保持ユニット30に対して相対的に回転可能な状態となる。この状態で、光源ユニット10を、照射方向が照明器具5の照射方向と一致するように回転させる。LEDランプ1の照射方向が、照明器具5の照射方向と一致した位置で光源ユニット10を軸方向に引いている力から解放すると、ばね35の付勢力により、光源ユニット10が、光源保持ユニット30に対して軸方向に押し込まれる。光源ユニット10が、光源保持ユニット30に対して軸方向に押し込まれると、図8(C)及び図8(D)に示すように、光源ユニット10と光源保持ユニット30は連結状態となる。この連結状態では、突起41A、41Bが互いに噛み合った状態となり、光源ユニット10と光源保持ユニット30との相対的な回転が規制される。 In the LED lamp 1, since the light source module 20 is disposed on the surface of the base 16 connected in a V shape, the base 40 is screwed into the socket 105 of the instrument main body 100 so that the LED lamp 1 is attached to the instrument main body 100. When fixed with respect to 100, the irradiation direction of the LED lamp 1 may not coincide with the irradiation direction of the lighting fixture 5. When the irradiation direction of the LED lamp 1 does not coincide with the irradiation direction of the luminaire 5, the light source unit 10 is inserted into the socket 105 of the fixture body 100 with the base 40 of the LED lamp 1 screwed. Pull in the direction away from the base 40. Accordingly, as shown in FIGS. 8A and 8B, the engagement of the protrusions 41A and 41B between the male rotation adapter 33 and the female rotation adapter 34 is released, and the light source unit 10 is replaced with the light source holding unit. It will be in the state which can rotate relatively with respect to 30. FIG. In this state, the light source unit 10 is rotated so that the irradiation direction matches the irradiation direction of the lighting fixture 5. When the irradiation direction of the LED lamp 1 is released from the force that pulls the light source unit 10 in the axial direction at a position that coincides with the irradiation direction of the luminaire 5, the light source unit 10 is moved by the biasing force of the spring 35. Against the axis. When the light source unit 10 is pushed in the axial direction with respect to the light source holding unit 30, the light source unit 10 and the light source holding unit 30 are connected as shown in FIG. 8C and FIG. 8D. In this connected state, the protrusions 41A and 41B are engaged with each other, and the relative rotation between the light source unit 10 and the light source holding unit 30 is restricted.
 これらの構成によれば、光源ユニット10と光源保持ユニット30とを、連結状態と、相対的に回転可能な状態とを切り替え可能な構成としたため、光源ユニット10を光源保持ユニット30に接続したままの状態で、光源ユニット10を光源保持ユニット30に対して回転させることができ、LEDランプ1の照射方向を、照明器具5の照射方向に容易に一致させることができる。また、光源ユニット10を軸方向に引いて、回転させて、離すという簡単な作業で、LEDランプ1の照射方向を、照明器具5の照射方向に一致させることができ、取り付け作業性を向上することができる。また、LEDランプ1は、器具本体100に取り付けられた状態で、LEDランプ1の上端と器具本体100との間に空間Aが備えられているため、LEDランプ1を、器具本体100に固定したままで、光源ユニット10を軸方向に引いて、光源保持ユニット30に対して相対的に回転可能な状態とすることができる。 According to these configurations, since the light source unit 10 and the light source holding unit 30 can be switched between a connected state and a relatively rotatable state, the light source unit 10 remains connected to the light source holding unit 30. In this state, the light source unit 10 can be rotated with respect to the light source holding unit 30, and the irradiation direction of the LED lamp 1 can be easily matched with the irradiation direction of the lighting fixture 5. Further, the irradiation direction of the LED lamp 1 can be made to coincide with the irradiation direction of the lighting fixture 5 by a simple operation of pulling the light source unit 10 in the axial direction, rotating it, and releasing it, thereby improving the mounting workability. be able to. In addition, since the LED lamp 1 is attached to the instrument body 100 and the space A is provided between the upper end of the LED lamp 1 and the instrument body 100, the LED lamp 1 is fixed to the instrument body 100. As it is, the light source unit 10 can be pulled in the axial direction so as to be rotatable relative to the light source holding unit 30.
 また、雄回転アダプタ33および雌回転アダプタ34に、それぞれ周方向に並べて多数の突起41A,41Bを設けたため、光源ユニット10を、光源保持ユニット30に対して略無段階的に回転させることができる。よって、LEDランプ1の照射方向を、照明器具5の照射方向に正確に一致させることができる。本実施形態においては10°間隔で36個の突起41A、41Bを設けており、10°間隔で光源ユニット10の角度を調整することができる。
 また、光源ユニット10と、光源保持ユニット30とを相対的に回転可能な状態とした際でも、上述したストッパー38A,38Bにより、光源ユニット10と、光源保持ユニット30とは相対的に360°以上回転しない。この構成によれば、光源ユニット10を、光源保持ユニット30に対して相対的に回転させる際に、回転ユニット42の中心に設けられた導入孔37A,37Bを通って、光源ユニット10から口金40に延びるリード線24が、360°以上ねじれるのを防止することができる。
Further, since the male rotation adapter 33 and the female rotation adapter 34 are provided with a large number of protrusions 41A and 41B arranged in the circumferential direction, the light source unit 10 can be rotated substantially steplessly with respect to the light source holding unit 30. . Therefore, the irradiation direction of the LED lamp 1 can be exactly matched with the irradiation direction of the lighting fixture 5. In the present embodiment, 36 protrusions 41A and 41B are provided at intervals of 10 °, and the angle of the light source unit 10 can be adjusted at intervals of 10 °.
Further, even when the light source unit 10 and the light source holding unit 30 are in a relatively rotatable state, the light source unit 10 and the light source holding unit 30 are relatively at least 360 ° by the stoppers 38A and 38B described above. Does not rotate. According to this configuration, when the light source unit 10 is rotated relative to the light source holding unit 30, the light source unit 10 passes through the introduction holes 37 </ b> A and 37 </ b> B provided at the center of the rotation unit 42 and the base 40. It is possible to prevent the lead wire 24 extending in the direction of 360 ° from being twisted by 360 ° or more.
 なお、本実施形態では、光源ユニット10を、口金40の軸方向に引くことで、光源ユニット10と光源保持ユニット30とを相対的に回転可能な状態とする構成であるが、これに限らず、光源ユニット10を、口金40の軸方向に押し込むことで、光源ユニット10と光源保持ユニット30とを相対的に回転可能な状態とする構成であっても良い。光源ユニット10を、口金40の軸方向に押し込むことで、光源ユニット10と光源保持ユニット30とを相対的に回転可能な状態とする構成とした場合には、図示は省略するが、例えば、雄回転アダプタ33の柱部33Bに鍔状のフランジを設けて、当該フランジの下面に突起41Aを形成する。そして、雌回転アダプタ34の底板34Aの上面に設けた突起41Bと、雄回転アダプタ33の突起41Aとをかみ合わせて、光源ユニット10と、光源保持ユニット30とを連結状態にする構成とすることができる。この構成では、ばね35は、例えば、押さえ金具36と、雄回転アダプタ33の柱部33Bに設けられた鍔状のフランジとの間に配置されて、光源ユニット10を、口金40の軸方向に押し込むことで、ばね35が押し込められ、雄回転アダプタ33を押し戻す方向に付勢する。 In the present embodiment, the light source unit 10 is pulled in the axial direction of the base 40 to make the light source unit 10 and the light source holding unit 30 relatively rotatable. However, the present invention is not limited to this. The light source unit 10 and the light source holding unit 30 may be relatively rotated by pushing the light source unit 10 in the axial direction of the base 40. When the light source unit 10 is pushed in the axial direction of the base 40 so that the light source unit 10 and the light source holding unit 30 are relatively rotatable, the illustration is omitted. A flange-like flange is provided on the column portion 33B of the rotation adapter 33, and a protrusion 41A is formed on the lower surface of the flange. Then, the projection 41B provided on the upper surface of the bottom plate 34A of the female rotation adapter 34 and the projection 41A of the male rotation adapter 33 are engaged with each other so that the light source unit 10 and the light source holding unit 30 are connected. it can.
