Description

本発明は、例えば、発光ダイオード（以下、ＬＥＤと記載）に発生した熱を放熱する照明器具に関するものである。   The present invention relates to a lighting fixture that radiates heat generated in a light emitting diode (hereinafter referred to as LED), for example.

従来のＬＥＤランプを光源とした照明器具は、ＬＥＤランプの形状が一般照明用白熱電球と類似した形状であるため、ＬＥＤランプ自体に放熱手段を備え照明器具側では放熱対策をとっていなかった。
特許文献１に示されたＬＥＤランプは、複数のＬＥＤを配置するＬＥＤ配置面と、少なくとも複数のＬＥＤを覆うレンズと、電源供給を受ける口金と、発光ダイオード配置面と前記口金との間に配置される放熱部と、回路収納部とを有している。また、前記ＬＥＤ配置面の一方の面に前記複数のＬＥＤを実装し、他方の面を前記放熱部と接するように配置されるＬＥＤ基板を備える。また、前記回路収納部は前記放熱部と前記口金を連結する外装体を有する。そして、ＬＥＤランプはさらに点灯回路基板を備えているものとして開示されている。
この例に示されるように、従来は、ＬＥＤランプ自体に放熱部を形成し、この放熱部から熱を放散させている。
しかし、この放熱対策はＬＥＤランプに放熱手段を持たせているため放熱量に限界がある。
特開２００５−２８６２６７号公報 特開２００５−３８７９８号公報 Conventional lighting fixtures using an LED lamp as a light source have a shape similar to that of an incandescent light bulb for general lighting, and thus the LED lamp itself has a heat dissipation means and does not take heat dissipation measures on the side of the lighting fixture.
The LED lamp shown in Patent Document 1 is arranged between an LED arrangement surface on which a plurality of LEDs are arranged, a lens that covers at least the plurality of LEDs, a base that receives power supply, a light emitting diode arrangement surface, and the base. A heat radiating portion and a circuit housing portion. The LED board is provided with the plurality of LEDs mounted on one surface and the other surface disposed in contact with the heat radiating portion. The circuit housing portion includes an exterior body that connects the heat radiating portion and the base. The LED lamp is disclosed as further including a lighting circuit board.
As shown in this example, conventionally, a heat radiating portion is formed in the LED lamp itself, and heat is dissipated from the heat radiating portion.
However, this heat dissipation measure has a limit in the amount of heat dissipation since the LED lamp has a heat dissipation means.
JP 2005-286267 A JP 2005-38798 A

ＬＥＤランプで発生した熱を効率的にＬＥＤランプ外に放出するためには、ＬＥＤランプ自体の工夫では放熱量に限界がある。すなわち、ＬＥＤランプからの放熱経路はＬＥＤランプの透光性バルブ部分とＬＥＤランプに形成した放熱部とからの「放射熱伝導」と「対流熱伝導」、ＬＥＤランプの構成部材である口金からソケットへの「熱伝導」の３経路が考えられる。つまり、３つ目の放熱経路である「熱伝導」による照明器具への放熱先はソケットのみであり、他に工夫がされていないのが現状である。
そこで、ランプの口金以外への熱伝導が必要になるが、ＬＥＤランプの形状が従来のような一般照明用白熱電球に類似の形状では口金以外への熱伝導による放熱策を考えることは難しい。
また、口金が無いＬＥＤランプの放熱対策として、特許文献２には、平板状のＬＥＤランプをソケットに押圧して行う熱伝導による放熱対策が開示されている。
しかし、この放熱対策は、押圧の手段となる別部品が必要であることなど、コスト面で課題がある。 In order to efficiently release the heat generated in the LED lamp to the outside of the LED lamp, there is a limit to the amount of heat dissipation in the device of the LED lamp itself. That is, the heat radiation path from the LED lamp is “radiant heat conduction” and “convection heat conduction” from the light-transmitting bulb part of the LED lamp and the heat radiation part formed on the LED lamp, and the socket from the base that is a component of the LED lamp. There are three possible routes for “thermal conduction”. That is, the current heat dissipating destination to the lighting fixture by the “heat conduction” that is the third heat dissipating path is only the socket, and no other device is devised.
Therefore, heat conduction to a part other than the base of the lamp is necessary. However, when the shape of the LED lamp is similar to a conventional incandescent light bulb for general illumination, it is difficult to consider a heat dissipation measure by heat conduction to a part other than the base.
In addition, as a heat dissipation measure for an LED lamp without a base, Patent Document 2 discloses a heat dissipation measure by heat conduction performed by pressing a flat LED lamp against a socket.
However, this heat dissipation measure has a problem in terms of cost, such as the need for a separate part that serves as a pressing means.

本発明は、例えば、ＬＥＤランプを照明器具の部品に接触させ、接触部分から照明器具への熱伝導によってＬＥＤランプの熱を放熱させることを目的とし、また、ＬＥＤランプの取り付けを容易にすることを目的とする。   An object of the present invention is, for example, to bring an LED lamp into contact with a component of a lighting fixture and to dissipate heat of the LED lamp by heat conduction from the contact portion to the lighting fixture, and to facilitate the mounting of the LED lamp. With the goal.

本発明の照明器具は、側面と係止孔を有する端面と前記端面から前記側面と前記端面とが成す筒状の内側に突出して形成された係止板とを有する筒状体であり、この筒状体の外側から前記端面の前記係止孔と前記係止板とに光源と前記光源を配置する平板と前記平板から突出して形成する係止片とを有するランプの前記係止片を係止する筒状体を備えることを特徴とする。   The lighting fixture of the present invention is a cylindrical body having a side surface, an end surface having a locking hole, and a locking plate formed to project from the end surface to a cylindrical inner side formed by the side surface and the end surface. Engaging the locking piece of the lamp having a light source, a flat plate on which the light source is arranged, and a locking piece protruding from the flat plate from the outside of the cylindrical body to the locking hole and the locking plate of the end surface. It is characterized by including a cylindrical body that stops.

本発明によれば、例えば、ＬＥＤランプを筒状体の端面に接触させることにより、ＬＥＤランプで発生した熱を筒状体に熱伝導して端面と側面とから放熱することができる。また、筒状体の係止板にＬＥＤランプの係止片を係止することでＬＥＤランプを筒状体に取り付けることができる。   According to the present invention, for example, by bringing the LED lamp into contact with the end face of the cylindrical body, the heat generated by the LED lamp can be conducted to the cylindrical body and radiated from the end face and the side face. Moreover, an LED lamp can be attached to a cylindrical body by latching the latching piece of an LED lamp to the latching plate of a cylindrical body.

フランジ１０４は平面部１０２が位置しない方で開放した側面部１０１のもう一端側において側面部１０１の外方向に伸長（突出）して位置する。フランジ１０４はリング形、ドーナツ形を形成する。 In FIG. 2, the LED lamp fixture 100 (tubular body) has a side surface portion 101 (side surface) and a flat surface portion 102 (end surface), and forms a hollow cylindrical shape with one end open. Further, the LED lamp fixture 100 has a flange 104 (head) on the open end side to form a hat shape.

The flange 104 is positioned to extend (protrude) outward from the side surface portion 101 on the other end side of the side surface portion 101 that is open when the flat surface portion 102 is not positioned. The flange 104 forms a ring shape or a donut shape.

図３において、係止板７００はＬＥＤランプ２００を係止する係止面７０１と係止面７０１に高さを与える縦面７０４とＬＥＤランプ取付具１００の平面部１０２に結合する結合面７０５とによりＺ字形状、階段状を形成する。
また、係止板７００は係止面７０１において一端が開放したスリット７０６を有すると共に、平面部７０７と、スリット７０６の開放端側（第１の端部側）において斜め下方に伸びる傾斜部７０２と、スリット７０６の閉端側（第２の端部側）において平面部７０７との段差７０８がある凹部７０３とを有する。 In FIG. 3, the locking plate 700 includes a locking surface 701 that locks the LED lamp 200, a vertical surface 704 that gives the locking surface 701 a height, and a coupling surface 705 that is coupled to the flat portion 102 of the LED lamp fixture 100.

And a recess 703 having a step 708 with respect to the flat surface portion 707 on the closed end side (second end portion side) of the slit 706.

図４において、ＬＥＤランプ２００はピン式の口金２０５と基板２０２（平板）とＬＥＤ２０３（光源）とＬＥＤランプ取付具１００の係止板７００に係止する係止片２０８とを有する。
ピン式の口金２０５は基板２０２から突出して形成し、コネクタ３３０（図１参照）に結合してＬＥＤ２０３を電気的に接続する。
基板２０２は円形平板状を形成し、ピン式の口金２０５とＬＥＤ２０３（図１参照）と係止片２０８とを配置する。
ＬＥＤ２０３は基板２０２に複数配置された照明器具４００の光源である。
係止片２０８は基板２０２の周縁においてＬＥＤランプ取付具１００のだるま孔１０８（図２参照）と同じ数だけ存在する。 In FIG. 4, the LED lamp 200 includes a pin-type base 205, a substrate 202 (flat plate), an LED 203 (light source), and a locking piece 208 that is locked to the locking plate 700 of the LED lamp fixture 100.
The pin-type base 205 is formed so as to protrude from the substrate 202 and is coupled to the connector 330 (see FIG. 1) to electrically connect the LED 203.
The substrate 202 is formed in a circular flat plate shape, and a pin-type base 205, an LED 203 (see FIG. 1), and a locking piece 208 are disposed.
A plurality of LEDs 203 are light sources of the lighting fixture 400 arranged on the substrate 202.
The number of the locking pieces 208 is the same as the number of the dart holes 108 (see FIG. 2) of the LED lamp fixture 100 at the periphery of the substrate 202.

図５において、器具本体３００は側面部３０１と平面部３０２とを有して、ＬＥＤランプ取付具１００と同様に、円筒状を形成する。さらに、器具本体３００はＬＥＤランプ取付具１００と同様に平面部３０２の中央部に透孔３０４を有し、電気コード３０５に繋がるコネクタ３３０を透孔３０４から外出しする。このコネクタ３３０はＬＥＤランプ２００のピン式の口金２０５と機械的、電気的に接続し、ＬＥＤランプ２００に電力を供給する。また、器具本体３００は平面部３０２が位置しない側において内方向に伸長する取付部３０３を有する。   In FIG. 5, the instrument main body 300 has a side surface portion 301 and a flat surface portion 302, and forms a cylindrical shape like the LED lamp mounting tool 100. Furthermore, the instrument main body 300 has a through hole 304 at the center of the flat portion 302 in the same manner as the LED lamp fixture 100, and the connector 330 connected to the electric cord 305 is taken out from the through hole 304. The connector 330 is mechanically and electrically connected to the pin type cap 205 of the LED lamp 200 and supplies power to the LED lamp 200. In addition, the instrument main body 300 has an attachment portion 303 that extends inward on the side where the flat portion 302 is not located.

図５に示すように、器具本体３００は、取付部３０３において天井材などの器具取り付け板３１０に、木ネジや金属ネジなどのネジ３１１またはリベットや接着テープや接着材などのその他の取付手段で固定される。
ＬＥＤランプ取付具１００は、フランジ１０４においてネジ、リベット、接着テープ、接着剤などの取付手段により器具本体３００の平面部３０２に固定される。
そして、コネクタ３３０をＬＥＤランプ取付具１００から透孔１０６を通して外出しにし、ピン式の口金２０５をコネクタ３３０にはめ込むことでＬＥＤランプ２００の電気的な接続を容易に行うことができる。 As shown in FIG. 5, the instrument body 300 is attached to an instrument mounting plate 310 such as a ceiling material at a mounting portion 303 with screws 311 such as wood screws and metal screws, or other mounting means such as rivets, adhesive tapes, and adhesives. Fixed.
The LED lamp fixture 100 is fixed to the flat surface portion 302 of the instrument main body 300 by means of attachment means such as screws, rivets, adhesive tape, and adhesive at the flange 104.
Then, the LED 330 can be easily electrically connected by setting the connector 330 to the outside through the through hole 106 from the LED lamp fixture 100 and fitting the pin-type base 205 into the connector 330.

また、ピン式の口金２０５をはめ込んだコネクタ３３０を透孔１０６に挿通させると共に係止片２０８をだるま孔１０８に挿通させた後、図６に示すように、ＬＥＤランプ２００を回転させることで、ＬＥＤランプ２００の係止片２０８がＬＥＤランプ取付具１００のだるま孔１０８と係止板７００に係止する。これにより、ＬＥＤランプ２００の機械的な接続を容易に行うことができる。   Further, after inserting the connector 330 fitted with the pin-type base 205 into the through-hole 106 and inserting the locking piece 208 into the saddle hole 108, the LED lamp 200 is rotated as shown in FIG. The locking piece 208 of the LED lamp 200 is locked to the dart hole 108 and the locking plate 700 of the LED lamp fixture 100. Thereby, mechanical connection of the LED lamp 200 can be performed easily.

ＬＥＤランプ２００を回転させたとき、ＬＥＤランプ２００の係止片２０８はＬＥＤランプ取付具１００に取り付けられた係止板７００に図７に示すように係止される。
まず、係止片２０８が係止板７００の方向に移動する（図７上図ａ）。
次に、係止片２０８が係止板７００の傾斜部７０２の傾斜に沿って係止面７０１に誘導される（図７中図ｂ）。
そして、係止片２０８は係止板７００の平面部７０７を通り凹部７０３に係止する（図７下図ｃ）。
係止板７００は平面部７０７と凹部７０３とが形成する段差７０８により係止片２０８を保持することができる。つまり、係止板７００は係止片２０８が逆回転して係止板７００から外れることを防止することができる。 When the LED lamp 200 is rotated, the locking piece 208 of the LED lamp 200 is locked to a locking plate 700 attached to the LED lamp mounting tool 100 as shown in FIG.
First, the locking piece 208 moves in the direction of the locking plate 700 (a in FIG. 7A).
Next, the locking piece 208 is guided to the locking surface 701 along the inclination of the inclined portion 702 of the locking plate 700 (b in FIG. 7).
Then, the locking piece 208 passes through the flat portion 707 of the locking plate 700 and is locked to the recess 703 (the lower diagram in FIG. 7).
The locking plate 700 can hold the locking piece 208 by a step 708 formed by the flat portion 707 and the recess 703. That is, the locking plate 700 can prevent the locking piece 208 from rotating backward and coming off the locking plate 700.

また、係止板７００は弾性部材で成形し、ＬＥＤランプ２００の係止片２０８を弾性作用により上方へ持ち上げる。つまり、係止板７００はＬＥＤランプ２００の基板２０２をＬＥＤランプ取付具１００の平面部１０２に引き付け、ＬＥＤランプ２００とＬＥＤランプ取付具１００との密着性を高める。   The locking plate 700 is formed of an elastic member, and the locking piece 208 of the LED lamp 200 is lifted upward by an elastic action. That is, the locking plate 700 attracts the substrate 202 of the LED lamp 200 to the flat portion 102 of the LED lamp fixture 100, and improves the adhesion between the LED lamp 200 and the LED lamp fixture 100.

そして、係止片２０８を係止板７００に係止してＬＥＤランプ２００をＬＥＤランプ取付具１００に取り付けることにより、図１に示すように、ＬＥＤランプ２００の基板２０２の口金２０５側の面がＬＥＤランプ取付具１００の外側から平面部１０２に接触する。基板２０２と平面部１０２との接触部分を接触部１０３とする。   Then, by locking the locking piece 208 to the locking plate 700 and mounting the LED lamp 200 to the LED lamp mounting tool 100, as shown in FIG. The flat surface portion 102 is contacted from the outside of the LED lamp fixture 100. A contact portion between the substrate 202 and the flat portion 102 is referred to as a contact portion 103.

このとき、ＬＥＤ２０３から発生した熱が接触部１０３において基板２０２からＬＥＤランプ取付具１００の平面部１０２に熱伝導し、平面部１０２に移動した熱は側面部１０１およびフランジ１０４に熱伝導し、フランジ１０４に移動した熱は器具本体３００に熱伝導する。   At this time, the heat generated from the LED 203 is thermally conducted from the substrate 202 to the flat part 102 of the LED lamp fixture 100 in the contact part 103, and the heat transferred to the flat part 102 is conducted to the side part 101 and the flange 104, and the flange The heat transferred to 104 conducts heat to the instrument body 300.

ＬＥＤ２０３で発生しＬＥＤランプ取付具１００および器具本体３００に伝導した熱は、器具本体３００の側面部３０１や平面部３０２、ＬＥＤランプ取付具１００の側面部１０１や平面部１０２から熱放射し、また、対流して器具本体３００およびＬＥＤランプ取付具１００の内側と外側とで空気中に放散する。
また、ＬＥＤ２０３で発生した熱は基板２０２においても熱放射して空気中に放散する。 The heat generated by the LED 203 and conducted to the LED lamp fixture 100 and the fixture body 300 is radiated from the side surface portion 301 and the plane portion 302 of the fixture body 300, the side surface portion 101 and the plane portion 102 of the LED lamp fixture 100, and The convection is dissipated into the air inside and outside the fixture body 300 and the LED lamp fixture 100.
Further, the heat generated by the LED 203 is also radiated to the substrate 202 and dissipated into the air.

実施の形態１における照明器具４００は、ＬＥＤランプ２００の口金２０５以外の部材（基板２０２）とＬＥＤランプ取付具１００とが接触していることによりＬＥＤ２０３で発生した熱を口金２０５以外から熱伝導することができる。これにより、照明器具４００はＬＥＤ２０３で発生した熱をより多く放熱することができる。
また、ＬＥＤランプ取付具１００は側面部１０１を有することで外気に接する面積を広くしているため、ＬＥＤ２０３で発生した熱をより多く放熱することができる。
また、ＬＥＤランプ取付具１００は中空状であるため、ＬＥＤ２０３で発生した熱をＬＥＤランプ取付具１００の外側だけでなく内側へも放熱することができる。
また、ＬＥＤランプ取付具１００は器具本体３００に接することでＬＥＤ２０３で発生した熱を器具本体３００に伝導できるため、ＬＥＤ２０３で発生した熱を器具本体３００からも放熱することができる。
また、ＬＥＤランプ２００はＬＥＤ２０３を配置する基板２０２が平板状を形成することで外気に接する面積を広くしているため、ＬＥＤ２０３で発生した熱をＬＥＤランプ２００自体から効率よく放熱することができる。
また、ＬＥＤランプ取付具１００は弾性部材の係止板７００を有することでＬＥＤランプ２００とＬＥＤランプ取付具１００との密着性を高めているため、ＬＥＤランプ２００からＬＥＤランプ取付具１００への熱伝導性を高めることができる。そして、ＬＥＤランプ取付具１００はＬＥＤランプ２００との熱伝導性を高めることでＬＥＤ２０３で発生した熱に対する放熱効果を高めることができる。 The lighting fixture 400 according to Embodiment 1 conducts heat generated in the LED 203 from other than the base 205 due to the contact between the member (substrate 202) other than the base 205 of the LED lamp 200 and the LED lamp fixture 100. be able to. Thereby, the lighting fixture 400 can dissipate more heat generated by the LED 203.
Moreover, since the LED lamp fixture 100 has the side surface portion 101 to increase the area in contact with the outside air, more heat generated by the LED 203 can be dissipated.
Moreover, since the LED lamp fixture 100 is hollow, the heat generated by the LED 203 can be radiated not only to the outside of the LED lamp fixture 100 but also to the inside.
Moreover, since the LED lamp fixture 100 can conduct the heat generated by the LED 203 to the instrument body 300 by contacting the instrument body 300, the heat generated by the LED 203 can also be dissipated from the instrument body 300.
Moreover, since the board | substrate 202 which arrange | positions LED203 forms the flat form in the LED lamp 200, the area which contacts external air is widened, Therefore The heat | fever generate | occur | produced by LED203 can be thermally radiated from LED lamp 200 itself efficiently.
Further, since the LED lamp fixture 100 has an elastic member locking plate 700 to improve the adhesion between the LED lamp 200 and the LED lamp fixture 100, heat from the LED lamp 200 to the LED lamp fixture 100 is increased. Conductivity can be increased. And the LED lamp fixture 100 can improve the heat dissipation effect with respect to the heat | fever which generate | occur | produced in LED203 by improving thermal conductivity with LED lamp 200. FIG.

つまり、実施の形態１における照明器具４００は多くの放熱手段を有し、放熱効果を高めているため、ＬＥＤ２０３で発生した熱を効率的に放熱することができ、ＬＥＤランプ２００の温度を十分に下げることができる。
照明器具４００はＬＥＤランプ２００の温度を十分に下げることにより以下のような課題を解決できる。 That is, since the lighting fixture 400 in Embodiment 1 has many heat dissipating means and enhances the heat dissipating effect, the heat generated by the LED 203 can be efficiently dissipated, and the temperature of the LED lamp 200 can be sufficiently increased. Can be lowered.
The lighting fixture 400 can solve the following problems by sufficiently lowering the temperature of the LED lamp 200.

ＬＥＤ２０３を光源とするＬＥＤランプ２００は白熱電球などの従来の電灯に比べて、消費電力量が少ないことや寿命が長いことなどの長所を有するが、以下のような理由により熱に弱いという短所も有する。
各ＬＥＤ２０３は、例えば、１００ｍｍ（ミリメートル）角の基板に１０〜１００個程度の素子を配置して作られる。これら素子の一つ一つは０．１ｍｍ〜０．３ｍｍ角と非常に小さいため、発熱量が小さくても単位面積当たりの発熱量が非常に大きなものとなる。このため、６０Ｗ（ワット）の白熱電球の口金が１７０度程度の温度まで耐えられるのに対し、ＬＥＤランプ２００は６０度程度までの温度にしか耐えられない。 The LED lamp 200 using the LED 203 as a light source has advantages such as less power consumption and longer life compared to conventional lamps such as incandescent bulbs, but also has the disadvantage of being vulnerable to heat for the following reasons. Have.
Each LED 203 is made by arranging about 10 to 100 elements on a 100 mm (millimeter) square substrate, for example. Since each of these elements is as small as 0.1 mm to 0.3 mm square, even if the calorific value is small, the calorific value per unit area is very large. For this reason, the cap of a 60 W (watt) incandescent lamp can withstand temperatures up to about 170 degrees, whereas the LED lamp 200 can only withstand temperatures up to about 60 degrees.

実施の形態１における照明器具４００はＬＥＤランプ２００の温度を十分に下げることができるため、温度の上昇によるＬＥＤランプ２００の故障の防止を図ることができる。   Since the lighting fixture 400 in Embodiment 1 can sufficiently reduce the temperature of the LED lamp 200, it is possible to prevent the failure of the LED lamp 200 due to the temperature rise.

実施の形態１における照明器具４００はＬＥＤ２０３で発生した熱をＬＥＤランプ取付具１００と器具本体３００に熱伝導して放熱するため、ＬＥＤランプ２００の基板２０２、ＬＥＤランプ取付具１００の平面部１０２や側面部１０１やフランジ１０４、器具本体３００の平面部３０２や側面部３０１などには熱伝導性の高い部材を用いることが望ましい。例えば、ＬＥＤランプ２００の基板２０２、ＬＥＤランプ取付具１００の平面部１０２や側面部１０１やフランジ１０４、器具本体３００の平面部３０２や側面部３０１は金属製であるとよい。   Since the lighting fixture 400 in Embodiment 1 conducts and dissipates heat generated by the LEDs 203 to the LED lamp fixture 100 and the fixture main body 300, the substrate 202 of the LED lamp 200, the flat portion 102 of the LED lamp fixture 100, It is desirable to use a member having high thermal conductivity for the side surface portion 101, the flange 104, the flat surface portion 302, the side surface portion 301, etc. of the instrument body 300. For example, the substrate 202 of the LED lamp 200, the flat surface portion 102, the side surface portion 101, and the flange 104 of the LED lamp fixture 100, and the flat surface portion 302 and the side surface portion 301 of the instrument main body 300 may be made of metal.

また、熱伝導性を高めるためにはＬＥＤランプ２００とＬＥＤランプ取付具１００との密着性を高めるとよい。
そこで、ＬＥＤランプ２００とＬＥＤランプ取付具１００との少なくともいずれかにおいて接触部１０３に熱伝導性の高い弾性部材を有するとよい。弾性部材は基板２０２と同様な形状であると共に中央部に透孔１０６と同様な形状の孔を有する。例えば、基板２０２と透孔１０６とが円形であれば弾性部材はリング形、ドーナツ形である。
また、熱伝導性の高い弾性部材とは、例えば、シリコンパッドである。 Moreover, in order to improve thermal conductivity, it is good to improve the adhesiveness of the LED lamp 200 and the LED lamp fixture 100. FIG.
Therefore, it is preferable that at least one of the LED lamp 200 and the LED lamp fixture 100 has an elastic member having high thermal conductivity in the contact portion 103. The elastic member has the same shape as that of the substrate 202 and has a hole having the same shape as that of the through hole 106 at the center. For example, if the substrate 202 and the through hole 106 are circular, the elastic member has a ring shape or a donut shape.
The elastic member having high thermal conductivity is, for example, a silicon pad.

また、ＬＥＤランプ取付具１００の平面部１０２を図８に示すように下側（ＬＥＤランプ取付具１００の外側）に凸形状、山状に***させてＬＥＤランプ２００とＬＥＤランプ取付具１００との密着性を高めてもよい。このとき、平面部１０２の***した方から押力を加えた場合に平らに形状を変えるように平面部１０２には弾性を持たせる。そして、ＬＥＤランプ２００を回転させて図１に示すようにソケット３２０に取り付ける。このとき、ＬＥＤランプ２００から押力を受けて平らに形状を変えたＬＥＤランプ取付具１００の平面部１０２には山状に復元しようとするＬＥＤランプ２００方向への力が働くため、ＬＥＤランプ２００とＬＥＤランプ取付具１００との接触をより良くすることができる。
図８は、実施の形態１における山状に***させた平面部１０２を有するＬＥＤランプ取付具１００の断面図である。 Further, as shown in FIG. 8, the flat portion 102 of the LED lamp fixture 100 protrudes downward (outside of the LED lamp fixture 100) into a convex shape and a mountain shape so that the LED lamp 200 and the LED lamp fixture 100 You may improve adhesiveness. At this time, the flat surface portion 102 is given elasticity so as to change its shape flatly when a pressing force is applied from the raised portion of the flat surface portion 102. Then, the LED lamp 200 is rotated and attached to the socket 320 as shown in FIG. At this time, since the force in the direction of the LED lamp 200 to be restored to the mountain shape acts on the flat portion 102 of the LED lamp fixture 100 that has been flattened by receiving a pressing force from the LED lamp 200, the LED lamp 200 And the LED lamp fixture 100 can be further improved in contact with each other.
FIG. 8 is a cross-sectional view of LED lamp fixture 100 having flat portion 102 raised in a mountain shape in the first embodiment.

また、ＬＥＤランプ２００からＬＥＤランプ取付具１００と器具本体３００に効率よく熱を伝導するため、ＬＥＤランプ２００の基板２０２とＬＥＤランプ取付具１００の平面部１０２との接触部１０３の面積、ＬＥＤランプ取付具１００が器具本体３００に接するフランジ１０４の面積は広いほうがよい。
また、ＬＥＤランプ取付具１００と器具本体３００とから効率よく熱を放射、対流するため、ＬＥＤランプ取付具１００と器具本体３００の表面積は広いほうがよい。 Further, in order to efficiently conduct heat from the LED lamp 200 to the LED lamp fixture 100 and the instrument body 300, the area of the contact portion 103 between the substrate 202 of the LED lamp 200 and the flat portion 102 of the LED lamp fixture 100, the LED lamp The area of the flange 104 where the fixture 100 is in contact with the instrument body 300 should be large.
In addition, in order to efficiently radiate and convect heat from the LED lamp fixture 100 and the fixture body 300, the LED lamp fixture 100 and the fixture body 300 should have a large surface area.

また、図９に示すように、ＬＥＤランプ２００に側面部２０４を有することで外気に接する面積を増やし、ＬＥＤランプ２００自体からの放熱効果を高めてもよい。
図９は、実施の形態１における照明器具４００の断面図である。
側面部２０４は基板２０２の端部側に位置し基板２０２の端部に沿って形成し、基板２０２と側面部２０４とで一端が開口した筒形を形成する。つまり、側面部２０４の断面は基板２０２と同様な形状であり、例えば、基板２０２が円形であれば側面部２０４は円筒形である。 In addition, as shown in FIG. 9, the LED lamp 200 may have a side surface portion 204 to increase the area in contact with the outside air, thereby enhancing the heat dissipation effect from the LED lamp 200 itself.
FIG. 9 is a cross-sectional view of lighting fixture 400 in the first embodiment.
The side surface portion 204 is positioned along the end portion of the substrate 202 and is formed along the end portion of the substrate 202, and the substrate 202 and the side surface portion 204 form a cylindrical shape with one end opened. That is, the cross section of the side surface portion 204 has the same shape as the substrate 202. For example, if the substrate 202 is circular, the side surface portion 204 is cylindrical.

図１５は、実施の形態２における補助体６００を取り付ける前の照明器具４００の断面図である。
図１６は、実施の形態２における補助体６００を取り付けた後の照明器具４００の断面図である。
実施の形態２における照明器具４００について図１５に基づいて以下に説明する。
ＬＥＤランプ２００からＬＥＤランプ取付具１００への熱伝導性を高めるにはＬＥＤランプ２００とＬＥＤランプ取付具１００との密着性を高めるとよい。 FIG. 15 is a cross-sectional view of lighting fixture 400 before attaching auxiliary body 600 in the second embodiment.
FIG. 16 is a cross-sectional view of lighting fixture 400 after attaching auxiliary body 600 in the second embodiment.
The lighting fixture 400 in Embodiment 2 is demonstrated below based on FIG.
In order to increase the thermal conductivity from the LED lamp 200 to the LED lamp fixture 100, the adhesion between the LED lamp 200 and the LED lamp fixture 100 may be increased.

そこで、照明器具４００は外側からＬＥＤランプ２００をＬＥＤランプ取付具１００の平面部１０２に押圧する補助体６００を有することでＬＥＤランプ２００とＬＥＤランプ取付具１００との密着性を高めてもよい。   Therefore, the lighting fixture 400 may improve the adhesion between the LED lamp 200 and the LED lamp fixture 100 by having an auxiliary body 600 that presses the LED lamp 200 against the flat portion 102 of the LED lamp fixture 100 from the outside.

図１５において、補助体６００は側面部６０１と平面部６０２とを有し、ＬＥＤランプ取付具１００と同様に、一端が開放した中空円筒状を形成する。
側面部６０１は両端が開放し円筒形、パイプ形を形成する。また、側面部６０１はらせん状の溝を形成するネジ切り部６０７を有する。
平面部６０２は円盤形を形成し、側面部６０１の開放した一端側において側面部６０１の開放端を閉じるように位置する。また、平面部６０２は中央部に透孔６０６を有し、輪形、ドーナツ形を形成する。
また、補助体６００はＬＥＤランプ取付具１００よりひと回り大きく、ＬＥＤランプ取付具１００に被せることができる。そして、ＬＥＤランプ取付具１００に被せたとき、補助体６００はＬＥＤランプ取付具１００の側面部１０１を側面部６０１に内接する。 In FIG. 15, the auxiliary body 600 has a side surface portion 601 and a flat surface portion 602, and forms a hollow cylindrical shape whose one end is open, like the LED lamp fixture 100.
The side portion 601 is open at both ends to form a cylindrical shape or a pipe shape. Further, the side surface portion 601 has a threaded portion 607 that forms a spiral groove.
The flat surface portion 602 forms a disk shape and is positioned so as to close the open end of the side surface portion 601 on one open end side of the side surface portion 601. Moreover, the plane part 602 has a through hole 606 in the center, and forms a ring shape or a donut shape.
Further, the auxiliary body 600 is slightly larger than the LED lamp fixture 100 and can be put on the LED lamp fixture 100. When the LED lamp fixture 100 is put on the auxiliary body 600, the side surface portion 101 of the LED lamp fixture 100 is inscribed in the side surface portion 601.

また、ＬＥＤランプ取付具１００は側面部１０１にらせん状の溝を形成するネジ切り部１０７を有する。ＬＥＤランプ取付具１００のネジ切り部１０７は補助体６００のネジ切り部６０７と対になる。   The LED lamp fixture 100 also has a threaded portion 107 that forms a spiral groove in the side surface portion 101. The threaded portion 107 of the LED lamp fixture 100 is paired with the threaded portion 607 of the auxiliary body 600.

補助体６００はＬＥＤランプ取付具１００に被せて回転させることにより、図１６に示すようにＬＥＤランプ２００の周縁（周端部）を覆うようにしてＬＥＤランプ取付具１００と機械的に結合する。このとき、補助体６００は、図１６に示すように、平面部６０２の透孔６０６側の端部でＬＥＤランプ２００の基板２０２の周縁に接してＬＥＤランプ２００の基板２０２をＬＥＤランプ取付具１００の平面部１０２に押圧する。
これにより、補助体６００はＬＥＤランプ２００とＬＥＤランプ取付具１００との密着性を高めることができ、ＬＥＤランプ２００に対する放熱効果を高めることができる。
また、補助体６００の平面部６０２がＬＥＤランプ２００の基板２０２との接触部分から熱伝導し熱放射することにより、ＬＥＤランプ２００に対する放熱効果を高めることができる。 The auxiliary body 600 is mechanically coupled to the LED lamp fixture 100 so as to cover the peripheral edge (circumferential end) of the LED lamp 200 as shown in FIG. 16 by rotating over the LED lamp fixture 100. At this time, as shown in FIG. 16, the auxiliary body 600 is in contact with the periphery of the substrate 202 of the LED lamp 200 at the end of the flat portion 602 on the through hole 606 side, and attaches the substrate 202 of the LED lamp 200 to the LED lamp fixture 100. The flat portion 102 is pressed.
Thereby, the auxiliary body 600 can enhance the adhesion between the LED lamp 200 and the LED lamp fixture 100, and can enhance the heat dissipation effect on the LED lamp 200.
In addition, since the flat portion 602 of the auxiliary body 600 conducts heat and emits heat from the contact portion of the LED lamp 200 with the substrate 202, the heat dissipation effect on the LED lamp 200 can be enhanced.

実施の形態３では、補助体６００を有してＬＥＤランプ２００とＬＥＤランプ取付具１００との密着性を高めることにより、ＬＥＤランプ２００からＬＥＤランプ取付具１００への熱伝導性を高め、ＬＥＤランプ２００からＬＥＤランプ取付具１００への熱伝導性を高めることによりＬＥＤランプ２００に対する放熱効果を高める照明器具４００について説明した。   In the third embodiment, the auxiliary body 600 is provided to improve the adhesion between the LED lamp 200 and the LED lamp fixture 100, thereby increasing the thermal conductivity from the LED lamp 200 to the LED lamp fixture 100, and the LED lamp. The lighting fixture 400 which improves the heat dissipation effect with respect to the LED lamp 200 by increasing the thermal conductivity from the 200 to the LED lamp fixture 100 has been described.
