本発明は、LED(発光ダイオード)を光源として用いた電球型ランプ及び前記ランプを用いた照明装置に関し、特にその光源であるLEDによる温度上昇を抑制するのに適した冷却構造に関する。 The present invention relates to a lighting device using a bulb-shaped lamp and the lamp using an LED (light emitting diode) as a light source, in particular to a cooling structure suitable for suppressing the temperature increase due to LED is its light source.

近年、地球温暖化防止への意識の高まりと共に家電製品における省エネルギー(以下、省エネ)に関する関心が高くなってきており、その中でも従来の白熱電球に代わる電球として消費電力の少ないLED(発光ダイオード)を光源として用いた電球型ランプが開発され、広く普及し始めている。 Recently, energy saving (hereinafter, energy saving) with increasing awareness of global warming in home appliances have become high interest in the low power consumption LED (light emitting diode) as a light bulb in place of conventional incandescent bulbs Among them bulb-type lamp used as a light source have been developed and are beginning to spread widely.

LEDは温度が上昇するに従い、光出力の低下と共に寿命も短くなることが知られている。 LED in accordance with the temperature rises, it is known that the life is shortened with a decrease of the light output. このため、LEDを発光素子として用いた電球ではLEDの温度上昇を抑制することが求められている。 Accordingly, light bulbs with LED as a light emitting element are required to suppress the temperature rise the LED.

従来、このような課題に対し、たとえば、特許文献1記載のランプ装置のようにLEDから発する熱を外部に放出するための金属製放熱部(フィン等)を備えてLED部の温度上昇を防止する構造が開示されている。 Prevention conventionally, with respect to such problems, for example, the temperature rise of the LED unit comprises a metallic heat radiating portion for releasing the heat to the outside emanating from the LED as the lamp device described in Patent Document 1 (fin etc.) structure is disclosed.

また、前記の課題に対し、特許文献2記載の照明装置では、LED部の熱はLEDが配設された基板,金属体,支持部材,口金部,ソケット,照明器具の順に伝熱される構造が開示されており、前記伝熱方法によりLED部の温度上昇が抑制され、LEDが長寿命化される構造が開示されている。 Also, the problems with respect to, in the illumination device described in Patent Document 2, a substrate heat of the LED unit is the LED is disposed, the metal member, the support member, the base part, the socket, the structure is transferring heat to the order of the luminaire is disclosed, the temperature rise of the LED portion is suppressed by the heat transfer method, LED is discloses a structure that is long life.

さらに、特許文献3記載の電球型ランプでは、弾性絶縁部材からなる封止部材と弾性絶縁部材に埋設された熱伝導部材を口金部周囲のケース部に設けて、電球のソケット装着時にケース部の熱を熱伝導部材を介してソケットに伝達する構造が開示されている。 Furthermore, the bulb-type lamp described in Patent Document 3, a heat conductive member embedded in the sealing member and the elastic insulating member made of an elastic insulating member disposed on the case portion around the base part, the casing section when the bulb socket mounting structure for transmitting the socket heat through the heat conducting member is disclosed.

特許文献1記載のランプ装置では、金属製放熱部の表面積が放熱する熱量に比例するため、放熱部の面積が小さい場合には、放熱量が少なくなり、温度低下も減少する。 In the lamp device described in Patent Document 1, since the surface area of ​​the metallic heat radiating portion is proportional to the amount of heat to dissipate, when the area of ​​the heat radiating portion is small, the heat radiation amount is reduced, also reduces the temperature drop. そのため、発熱量に応じた一定以上の表面積が必要であり、例えば、電球の筐体部が小型の電球の場合には表面積の確保が難しくなることや、従来の照明器具に取り付ける際に、表面積を確保するために金属製放熱部の体積を大きくすることにより取り付け時に不具合が生じるなどの恐れがある。 Therefore, it is necessary constant over the surface area corresponding to the calorific value, for example, and the securing of the surface area is difficult when the housing portion of the bulb of a small light bulb, when installing the conventional luminaire, surface area there is a risk of failure during installation occurs by increasing the volume of the metallic heat radiating portion in order to ensure.

また、特許文献2記載の照明装置では、LED部の熱は、基板,金属体,支持部材,口金部,ソケット,照明器具の順に伝熱される構造となっており、LED部と口金部の距離が短く、LED部の基板及び口金部内の電源回路で生じた熱をグローブ内部の金属体等で逃がし、外部に金属製放熱部のない構造となっている。 Further, in the illumination device described in Patent Document 2, the heat of the LED unit, the substrate, a metal body, the support member, the base part, the socket has a structure that heat is transferred in the order of the luminaire, the distance of the LED unit and the base unit is short, escape the heat generated in the power supply circuit board and the base part of the LED unit in the glove inside the metal body or the like, has a structure without a metallic heat radiating portion to the outside. このような口金伝熱のみによる放熱構造では、LEDの温度を低減し長寿命化を実現することが困難となる恐れがある。 In such a heat radiation structure according mouthpiece heat transfer only such, it may be difficult to realize a reduced temperature of the LED longer life.

また、特許文献3記載の電球型ランプでは、弾性絶縁部材からなる封止部材と弾性絶縁部材に埋設された熱伝導部材を口金部周囲のケース部に設けて、電球のソケット装着時にケース部の熱を熱伝導部材を介してソケットに伝達する構造となっている。 Further, in the bulb-type lamp described in Patent Document 3, a heat conductive member embedded in the sealing member and the elastic insulating member made of an elastic insulating member disposed on the case portion around the base part, the casing section when the bulb socket mounting thermal has a structure for transmitting to the socket via a heat conducting member. しかし、ソケットは陶器、セラミックやプラスチック等の絶縁性の非金属部材で構成されることが多いため、ケース部の熱が埋設された熱伝導部材を介してソケット部に伝熱されたとしても、熱伝導率が低い部材が使用されているため、熱抵抗が高く、熱が逃げにくく、LED部やケース部の温度を低減しにくい等の恐れがある。 However, sockets pottery, since it is often made of electrically insulating non-metal member such as a ceramic or plastic, even if they are transferred to the socket portion via the heat transfer member heat is embedded in the casing portion, since the thermal conductivity is lower members are used, the heat resistance is high, heat is hardly escape, there is a risk of such difficult to reduce the temperature of the LED unit and the case portion.

また、図13のような従来例においては、発光素子3において発生した熱は、基板4,電球筐体である外郭部材2を通って口金部6に伝導し、ソケット30の電極受金を経由して電源配線へ熱放散するように期待される。 Further, in the conventional example as in FIG. 13, the heat generated in the light-emitting element 3, a substrate 4, and conducted to the base part 6 through the outer member 2 is a lamp casing, via the electrode receiving metal socket 30 It expected to heat dissipation to the power wiring to. しかし、口金部6には電流が通るが、外郭部材2には電流は通らないという構造上の制約から、前記2つの部材は、異なる部材で構成され、また、接合部分にも従来の絶縁部材23を設けることが必要なため、伝熱経路が分断されることが多く、熱が効率的に伝導しにくい構造となっていた。 However, although the passage of current to the base part 6, the structural limitation that the outer member 2 current does not pass through, the two members are composed of different members, also in the joint portion of the conventional insulating member since it is necessary to provide 23, often heat transfer path is divided, the heat has been a efficient conduction occurs hardly. この場合の外郭部材(筐体)−口金接続構造の詳細は図14(a)〜(b)に示す通りである。 The outer member when (housing) - details of the base connection structure is as shown in FIG. 14 (a) ~ (b). 図14(a)は従来のLED電球の外郭部材(筐体)−口金接続構造を示す全体図であり、(b)は外郭部材2が円筒形状の場合の外郭部材(筐体)−口金接続構造の詳細図である。 FIG. 14 (a) outer member of a conventional LED bulb (housing) - is an overall view showing a mouthpiece connecting structure, (b) the outer member when the outer member 2 is of cylindrical shape (housing) - mouthpiece connected it is a detailed view of the structure.

また、図15には外郭部材(筐体)−口金接続構造9の口金部6,絶縁部材23,外郭部材2の斜視図を示す。 Further, the outer member 15 (housing) - the base part 6, the insulating member 23 of the base connection structure 9 shows a perspective view of the outer member 2. 図14及び図15より、口金部6は絶縁部材23を介して、外郭部材2に圧着,接着,ねじ込み等で固定される。 From 14 and 15, the base part 6 via the insulating member 23, pressed against the outer member 2, the adhesive is fixed by screwing or the like. 絶縁部材23には、PBT樹脂等の樹脂性部材や磁気,プラスチック,ガラス等の耐熱性を有する絶縁部材で構成されることが一般的である。 The insulating member 23, a resin member or a magnetic, such as PBT resin, plastic, it is constituted by an insulating member having heat resistance such as glass is common. 前記のような材料の絶縁部材では熱伝導率が金属に比較して低いものが多く、かつ絶縁部材23と口金部6との接触部分及び絶縁部材23と外郭部材2との接触部分の面積が小さいため、熱抵抗が高くなり、LED搭載部から外郭部材2に伝導した熱の口金部6に移動する熱流束量は低く制限されるため、熱が外郭部材2に滞留し、電球全体の温度が上昇する要因となることがわかっている。 The area of ​​the contact portion between the contact portion and the insulating member 23 and the outer member 2 with the insulating member materials often those having a low thermal conductivity as compared with metal, and the insulating member 23 and the base part 6 as described above small, the heat resistance is high, the heat fluence to move from the LED mounting portion to the cap portion 6 of the heat conducted to the outer member 2 is limited to a low, heat is accumulated in the outer member 2, the entire bulb temperature There has been found to be a factor to rise.

本発明は、電球筐体(外郭部材)の表面積を大きくすることなく、LED搭載部で生じた熱量を口金部に効率的に逃がすことにより、電球筐体(外郭部材)からの放射と口金伝熱の両方の放熱対策が可能であり、LED部の温度上昇を抑制する効果のあるLED電球を提供するものである。 The present invention, without increasing the surface area of ​​the lamp casing (outer member), by escape efficiently to the base portion the amount of heat generated in the LED mounting part, the radiation and the base heat transfer from the lamp casing (outer member) a possible heat dissipation of both heat and provides a LED light bulb with the effect of suppressing the temperature rise of the LED unit.

以下、本発明の実施例を説明する。 Hereinafter, an embodiment of the present invention. 各実施例において同一番号は同一の構成部位を示している。 Same number in each example indicates the same components.

図1は電球1の縦断面図である。 Figure 1 is a longitudinal sectional view of the bulb 1. 図1において1は本発明の照明装置であるLED電球である。 1 is an LED bulb which is an illumination apparatus of the present invention in FIG. LED電球1は、金属製の外郭部材2で構成される電球筐体(外郭部材2)と、発光素子3と、発光素子3を搭載した基板4と、透光性カバー5と、外郭部材2の内部に格納された点灯回路21と、点灯回路21を収容し保護する樹脂製収容部材22と、ツバ付口金16と絶縁部材24と電線8a,8bとを具備している。 LED bulbs 1, lamp casing consists of a metal outer shell member 2 (outer member 2), a light-emitting element 3, a substrate 4 mounted with the light emitting element 3, a translucent cover 5, the outer member 2 a lighting circuit 21 that is stored inside of a resin housing member 22 for protecting houses the lighting circuit 21, and includes a flange with cap 16 insulating member 24 and the wire 8a, and 8b. 外郭部材2は例えばアルミニウム等の金属の成形品で構成されている。 Outer member 2 is formed by a molded piece of metal such as aluminum. 外郭部材2は図1に示すように基板4を取り付け可能な載置部7を有している。 Outer member 2 has a mounting portion 7 can be attached to the substrate 4 as shown in FIG. LED等の発光素子3は、基板4の一方面(基板4の上)に配置される。 Emitting element 3 such as an LED is disposed on one surface of the substrate 4 (on the substrate 4). 基板4は外郭部材2の載置部7に、ネジ,圧着、または接着剤等により密着するよう取り付けられている。 The substrate 4 on the placing part 7 of the outer member 2, as attached to contact screws, crimping, or by an adhesive or the like. これにより、発光素子3で生じた熱は発光素子3が設けられている基板4に至る。 Accordingly, the heat generated in the light emitting element 3 reaches the substrate 4 to the light-emitting element 3 is provided. 基板4に至った熱は基板4が取り付けられる載置部7に至る。 Heat that has reached the substrate 4 reaches the mounting portion 7 in which the substrate 4 is mounted.

外郭部材2は、外郭部材2の外部の空気等に熱を伝える放熱面としての機能と、口金へ熱を伝えるという機能とを有するものである。 Outer member 2 are those having a function as a heat dissipation surface for transmitting heat to the air outside the outer member 2 and the like, and a function of transferring heat to the spinneret. 本実施例では、外郭部材2は、載置部7から口金部6に向けて(上方向から下方向に向けて)次第に径が小さくなる円錐状の部分と円筒状の部分とで形成されている。 In this embodiment, the outer member 2 is formed with a conical portion toward the mounting portion 7 to the base part 6 (from above toward the bottom direction) gradually diameter decreases and a cylindrical portion there. 載置部7は円錐状の部分の底面部(外郭部材の上方向)に設けられている。 Placing part 7 is provided on the bottom surface of the cone-shaped portion (the upper direction of the outer member). 外郭部材2は上記形状に限るものではなく、円筒形状や円錐形状でもよい。 Outer member 2 is not limited to the above shape, but may be cylindrical or conical shape. 円筒形状や円錐形状でも同様の放熱面としての機能や口金への伝熱機能は期待できる。 Cylindrical and the heat transfer function to the function and the die as same heat dissipation surface in conical shape can be expected.

外郭部材2は本実施例に記載した金属製に限るものではない。 Outer member 2 is not limited to metal as described in this example. 外郭部材2は放熱する機能と、口金へ伝熱する機能を有することが求められるため、高熱伝導性部材で構成されればよい。 Outer member 2 and the function of heat dissipation, since it is required to have the transfer heat function to the die, may be made by the high heat conductivity member.

外郭部材2の載置部7には透光性カバー5を取り付けるための図示しない溝部が形成されている。 Grooves (not shown) for attaching the translucent cover 5 is formed in the mounting portion 7 of the outer member 2. 透光性カバー5は、時にケース部の熱を熱伝導部材を介してソケットに伝達する構造が開示されている。 Translucent cover 5, a structure of at casing of the heat transferred to the socket via the heat conducting member is disclosed.

透光性カバー5は、半球状をしておりその開口縁部を外郭部材2の溝部に嵌め込み、ネジや接着剤等により外郭部材2に固定される。 Translucent cover 5 is fitted to the opening edge has a semi-spherical groove of the outer member 2 is fixed to the outer member 2 by screws or an adhesive. その結果、透光性カバー5は発光素子3を覆うこととなり、発光素子3は透光性カバー5の内面に対向することとなる。 As a result, the translucent cover 5 becomes possible to cover the light-emitting element 3, the light-emitting element 3 and thus opposed to the inner surface of the translucent cover 5.

透光性カバー5はガラスまたは合成樹脂等の材料により構成される。 Translucent cover 5 is made of a material such as glass or synthetic resin.

外郭部材2とツバ付口金16の内部は中空となっている。 Inside of the outer member 2 and the flange with cap 16 has a hollow. 外郭部材2とツバ付口金16の内部には樹脂製収容部材22が格納される。 Inside the outer member 2 and Flanged mouthpiece 16 resin housing member 22 is stored. 樹脂製収容部材22はPBT樹脂等の絶縁部材で製作されており、電線8や基板4以外と導電することを防いでいる。 Resin housing member 22 are made of an insulating member such as PBT resin, and it prevents the conductive and non-electric wire 8 and the substrate 4. 樹脂製収容部材22内部には点灯回路21と電線8の一部が格納されている。 Inside the resin housing member 22 a part of the lighting circuit 21 and the electric wire 8 is stored. 点灯回路21の温度が上昇すると素子等の寿命を低下させる恐れがある。 Temperature of the lighting circuit 21 is likely to reduce the lifetime of the device such as the rise. 収容部材22により点灯回路21を覆うことで、外郭部材2の熱が点灯回路21に伝わることを防ぎ、点灯回路21を熱より防いでいる。 By the accommodating member 22 to cover the lighting circuit 21 prevents the thermal shell member 2 is transmitted to the lighting circuit 21, the lighting circuit 21 is prevented from heat. ここで、収容部材22は樹脂で製作するとしたが、この限りでない。 Here, the housing member 22 was manufactured with a resin, this shall not apply. 外部からの熱が点灯回路21に伝わらなければよいので熱伝導性が低い部材であればよい。 Since heat from the outside may be transmitted to the lighting circuit 21 may be a low thermal conductivity member.

また、樹脂製収容部材22内部に図示しない高伝導性樹脂を埋め込むことにより、点灯回路21が発する熱を樹脂製収容部材22を介して外郭部材2等へ伝熱し逃がすことも可能である。 Further, by embedding a highly conductive resin (not shown) inside the resin housing member 22, it is possible to escape conducts the heat to the outer member 2 and the like through the resin housing member 22 to heat the lighting circuit 21 is emitted.

図4は本発明の外郭部材(筐体)−口金接続構造9の斜視図を示している。 Figure 4 is the outer member (housing) of the present invention - shows a perspective view of the base connection structure 9.

従来は片側のみ開放された円筒状の部材であった口金部6を、図4に示すように外郭部材2の底面部2aに接するようなツバ部16aを有するツバ付のツバ付口金16に変更することとした。 Change mouthpiece 6 was a cylindrical member which is open only on one side, the flange with cap 16 dated flange having a flange portion 16a such as to be in contact with the bottom surface portion 2a of the outer member 2 as shown in FIG. 4 is a conventional It was decided to. 図4においては、これまでの口金部6の開放された側の端面を外周方向に延伸し、円筒状の口金部6から帽子形状のツバ付口金16へと外郭部材2のリング状の底面部2aと接する面積を大きくすることで、熱抵抗を下げる効果を奏する。 Figure in 4, which until the end surface of the open side of the base portion 6 extending in the outer circumferential direction of the outer member 2 of the ring-shaped bottom portion of a cylindrical cap portion 6 to the flange with the die 16 of the hat shape by increasing the area in contact with the 2a, the effect of lowering the thermal resistance.

ツバ付口金16は円筒状部分16bと、先端部16cと、ツバ部16aを有している。 Flanged cap 16 has a cylindrical portion 16b, and the tip portion 16c, the flange portion 16a. 先端部16cはその先端から円筒状部分16bまでその径が徐々に大きくなる構成をしている。 Tip 16c has a progressively larger configuration the diameter from its distal end to the cylindrical portion 16b. 先端部16cの他端と円筒状部分16bの一端はつながっている。 One end of the other end of the tip portion 16c and the cylindrical portion 16b is connected. 円筒状部分16bにはソケット等と接続するための部分を有している。 The cylindrical portion 16b has a portion for connection with the socket or the like. ソケット等と接続するための部分は螺旋形状や蛇腹形状をしている。 Portion for connection with the socket or the like has a spiral shape or a bellows shape. 円筒状部分16bの他端とツバ部16aの一端はつながっている。 One end of the other end flange 16a of the cylindrical portion 16b is connected. ツバ部16aは円筒状部分16bの外径よりも大きな外径を有する円盤形状をしている。 Flange 16a has a disc shape having an outer diameter greater than the outer diameter of the cylindrical portion 16b. ツバ付口金16においてはツバ部16aのある側のみが開口している。 Only the side where the flange portion 16a is opened in Flanged mouthpiece 16.

また、本実施例ではツバ付口金16は一体で形成されているが、サイズ調整を行うために切り欠いた場合や、加工,製造上の容易さから2つ以上の部材(例えば半円形状部材)等の複数の分割部材で構成された場合も同等の放熱効果が期待できる。 Further, in the present embodiment Flanged cap 16 are formed integrally, and if notched in order to perform resizing, machining, two or more members from the ease of manufacture (e.g., semi-circular member ) equivalent heat dissipation effect even if it is composed of a plurality of divided members, such as can be expected.

図5(a)〜(d)にツバ付口金16を用いた場合の外郭部材(筐体)−口金接続構造9の断面構成図を示す。 Figure 5 (a) ~ the outer member in the case of using a flange with cap 16 (d) (housing) - shows a cross-sectional view of the base connection structure 9.

図5(a)〜(d)において、ツバ付口金16のツバ部16aは、外郭部材2の口金側の底面部2aと重複するように構成される。 In FIG. 5 (a) ~ (d), the flange portion 16a of the flange with the die 16 is configured to overlap the bottom portion 2a of the base side of the outer member 2. 然るに、ツバ付口金16のツバ部16aと外郭部材2の底面部2aがそのまま接触するように構成すると、外郭部材2の口金側の底面部2aからツバ付口金16に熱が伝達されると共にツバ付口金16から外郭部材2の口金側の底面部2aに電気も伝達されることになる。 However, the flange together with the bottom portion 2a of the flange portion 16a and the outer member 2 of the flange with the die 16 is configured to contact directly, heat the Flanged cap 16 from the cap side of the bottom portion 2a of the outer member 2 is transmitted electricity with cap 16 on the bottom surface 2a of the base side of the outer member 2 is also to be transmitted. ツバ付口金16から外郭部材2に電気が伝達される構成では、電球1をソケット等に取り付けた後に人が外郭部材2に触れると感電する恐れが生じる。 In the configuration electricity from Flanged cap 16 in the outer member 2 is transmitted, a possibility that human bulb 1 after attaching the socket or the like is an electric shock from touching the outer member 2 occurs. ツバ付口金16から外郭部材2への電気の伝達を防ぐため、ツバ付口金16と外郭部材2との間には絶縁部材24が挿入される。 To avoid electrical transmission from Flanged cap 16 to the outer member 2, an insulating member 24 is inserted between the flange with the die 16 and the outer member 2. 絶縁部材24が挿入されることで電気の伝達を防ぐことができる。 It is possible to prevent the transmission of electricity to the insulating member 24 is inserted. また、絶縁部材24は、ツバ付口金16と外郭部材2の底面部2aとにほぼ重複するようなリング状の部材で構成されている。 The insulating member 24 is composed of a ring-shaped member so as to substantially overlap the bottom portion 2a of the flange with the die 16 and the outer member 2. 絶縁部材24において、ツバ付口金16や外郭部材2と接触する部の面積は、ツバ付口金16のツバ部16aや外郭部材2の底面部2aとほぼ同等程度の面積を有することが望ましい。 In the insulating member 24, the area of ​​the parts in contact with the flange with the die 16 and the outer member 2, it is desirable to have a substantially equal degree of area and the bottom surface portion 2a of the flange portion 16a and the outer member 2 of the flange with the die 16. 絶縁部材24の接触部の面積をツバ付口金16のツバ部16aや外郭部材2のリング状の底面部2aの面積と同程度とすることで熱抵抗を低くすることができ、リング状の底面部2aからツバ部16aへの伝熱効果が高くなる。 It is possible to reduce the thermal resistance by the area about the same flange 16a and the outer member 2 a ring-shaped bottom surface portion 2a of the flange with the die 16 and the area of ​​the contact portion of the insulating member 24, a ring-shaped bottom surface heat transfer effect of the flange portion 16a is increased from part 2a. 絶縁部材24は、熱の伝導を良くするためには絶縁性を損なわない程度に最大限薄く、例えば1.6mmの厚さに構成されることが望ましい。 The insulating member 24, in order to improve the heat conduction is thin maximally to the extent of not impairing the insulating property, for example, it is configured to have a thickness of 1.6mm desirable. これは、ツバ付口金16と外郭部材2の底面部2aとの間に空気層が生じる可能性がある場合にはツバ付の口金16のツバ部16aと外郭部材2の底面部2a間の沿面距離は1.6mm以上が必要という電気安全法令等(JIS規格:C6950−1)の制約条件があるためである。 This creeping between the bottom portion 2a of the flange portion 16a and the outer member 2 of the cap 16 dated when there is a possibility that the air layer occurs collar between the bottom portion 2a of the flange with the die 16 and the outer member 2 distance electrical safety laws and regulations that must be at least 1.6mm (JIS standard: C6950-1) it is because there is a constraint.

ただし、ツバ付口金16と絶縁部材24と外郭部材2が後述の絶縁カバー26で覆われ、かつ内部に空気層が生じない場合には、沿面距離は上記制約条件に制限されることはない。 However, insulation and Flanged cap 16 member 24 and the outer member 2 is covered with an insulating cover 26 which will be described later, and when the air layer is not generated inside, creeping distance is not to be limited to the constraints.

さらに、ツバ付口金16と絶縁部材24と外郭部材2との間に空気層が生じると熱伝導が妨げられることから、前記の3部材は可能な限り圧着して接触することが望ましい。 Further, since the heat conducting the air layer is formed between the flange with the die 16 and the insulating member 24 and the outer member 2 is prevented, it said third member is preferably in contact with crimped as possible.

ツバ付口金16はセラミックや樹脂等でも形成可能であるが、材料の熱伝導性・導電性・コスト・加工上の容易性やネジを切る必要があることから耐久性などの点で優位性を持つ金属材料で形成されることがより望ましい。 Although Flanged cap 16 can also be formed of a ceramic or resin, a point in superiority of durability it is necessary to cut the ease and screws on the thermal conductivity, electrical conductivity, cost and processability of the material formed of a metal material having more desirable.

さらに絶縁部材24には、絶縁性を有すると共に高い熱伝導性を有する材料、たとえば窒化アルミ(AlN)や高熱伝導樹脂部材であるエラストマ等を用いることが望ましい。 Furthermore the insulating member 24, a material having a high thermal conductivity and having an insulating property, for example, it is desirable to use an elastomer such as a high heat conductive resin member and an aluminum nitride (AlN). なお、絶縁部材24の材料は、高絶縁性と高熱伝導性を兼ね備える材料であれば良く、前記材料に限るものではない。 The material of the insulating member 24 may be any material having both high insulation and high thermal conductivity, it is not limited to the material. さらに、耐熱性,密着容易性等も兼ね備えることがあればより好ましい。 Further, heat resistance, and more preferably if that combine also adhesion easiness. 絶縁部材24は金属,磁器,セラミックス、または樹脂材料等で構成される。 The insulating member 24 is made of metal, porcelain, ceramic or resin material.

図5(a),(b)では前記に示したように外郭部材(筐体)−口金接続構造9においては、外郭部材2と絶縁部材24とツバ付口金16の3部材の重複部分に人が触っても感電しないように絶縁カバー26が設けられている。 Figure 5 (a), (b) the outer member as shown in the in (housing) - In mouthpiece connection structure 9, people overlap 3 members of the outer member 2 and the insulating member 24 and the flange with the mouthpiece 16 An insulating cover 26 so as not to shock is provided to touch the. 絶縁カバー26はABS樹脂等の絶縁性部材で構成されており、電球取り付け,取り外し時の安全性を確保するのに必要な部材となっている。 Insulating cover 26 is made of an insulating member such as ABS resin, and has a member that is necessary to ensure the bulb mounting, safety during removal. なお、絶縁カバー26の部材は絶縁性が確保できれば、他の材料を用いることも可能である。 Incidentally, members of the insulating cover 26 is also possible to use if secure the insulating property, the other materials. 絶縁カバー26はツバ付口金16のツバ部16aと絶縁部材24をそれぞれの部材の外側から覆うように設けられている。 Insulating cover 26 is provided so as to cover the flange portion 16a and the insulating member 24 of the flange with the die 16 from the outside of the respective members.

図5(a)は前記3部材の重複部分の面積が最大限確保された場合における絶縁カバー26のカバー状態を示す図である。 5 (a) is a diagram showing the cover state of the insulation cover 26 in a case where the area of ​​the overlapped portion of the third member is maximally secured. 図5(a)の場合、重複部分の面積が最大限確保されることから熱抵抗を低く保つことが可能となる。 For FIG. 5 (a), the area of ​​the overlapped portion becomes possible to maintain a low thermal resistance from being maximally secured. 図5(a)に示すとおり、絶縁カバー26は外郭部材2より外側に少し突出した状態で構成されている。 As shown in FIG. 5 (a), the insulating cover 26 is composed in a state of slightly protruding from the outer member 2 to the outside. この場合、外郭部材2のリング状の底面部2aの面積と絶縁部材24の接触部の面積とツバ付口金16のツバ部16aの面積はほぼ同じである。 In this case, the area of ​​the contact portion of the area and the flange portion 16a of the flange with the die 16 of the areas and the insulating member 24 of the outer member 2 a ring-shaped bottom portion 2a is substantially the same. これにより熱抵抗を低くすることができ、伝熱効果が大きくなる。 This makes it possible to lower the thermal resistance, heat transfer effect becomes large. 外郭部材2のリング状の底面部2aの面積と絶縁部材24の接触部の面積とツバ付口金16のツバ部16aの面積がほぼ同じであるため、これらの部材の外側から絶縁カバー26を設けると絶縁カバー26の厚さ分外側に出た形状となる。 Since the area of ​​the contact portion of the area and the flange portion 16a of the flange with the die 16 of the area of ​​the ring-shaped bottom surface portion 2a of the outer member 2 and the insulating member 24 is approximately the same, an insulating cover 26 from the outside of these members a shape which comes into the thickness of the outer insulating cover 26 and. つまり図5(a)のように絶縁カバー26を設けた場合、外郭部材2の口金部側の外径は絶縁カバー26の外径よりも小さくなる。 That case in which the insulating cover 26 as shown in FIG. 5 (a), the outer diameter of the base portion side of the outer member 2 is smaller than the outer diameter of the insulation cover 26.

一方、図5(b)ではデザイン性やコンパクト性を重視した場合の外郭部材(筐体)−口金接続構造9を示している。 On the other hand, the outer member (housing) in the case of emphasis on the design and compactness FIG 5 (b) - represents a die connection structure 9. 前記3部材の重複部分の面積が図5(b)に比較して少し小さくなっており、絶縁カバー26が外郭部材2の外周部分と段差が無い状態になるように構成されている。 Area of ​​the overlapped portion of the third member has a little smaller than in FIG. 5 (b), the insulating cover 26 is configured such that in a state the outer peripheral portion and the step of the outer member 2 is not. この場合、絶縁部材24の接触部の面積とツバ付口金16のツバ部16aの面積はほぼ同じであるが、これらの面積は外郭部材2のリング状の底面部2aの面積よりも小さくなる。 In this case, although the area of ​​the contact portion of the area and the flange portion 16a of the flange with the die 16 of the insulating member 24 are substantially the same, these areas are smaller than the area of ​​the ring-shaped bottom surface portion 2a of the outer member 2. 外郭部材2の外周部分と段差がない状態になるようにするためには、絶縁部材24の外径とツバ付口金16のツバ部16aの外径が外郭部材2のリング状の底面部2aの外径よりも絶縁部材24の厚さ分小さければよい。 In order to be the absence of the outer peripheral portion and the step of the outer member 2 has an outer diameter of the outer diameter and the collar portion 16a of the flange with the die 16 of the outer member 2 of the ring-shaped bottom surface portion 2a of the insulating member 24 it is smaller the thickness of the insulating member 24 than the outer diameter. 段差が無いことで電球自体がコンパクトになる効果や、電球取り付けの際の引っかかりなどが無くなる効果を奏する。 Effect and the bulb itself becomes compact by the step is not an effect of catching and eliminated during the bulb mounting. つまり図5(b)のように絶縁カバー26を設けた場合、外郭部材2の口金部側の外径と絶縁カバー26の外径とは略同一となる。 That case in which the insulating cover 26 as in FIG. 5 (b), becomes substantially the same outer diameter of the base part side of the outer member 2 and the outer diameter of the insulation cover 26.

ここで、電球の大きさは小型電球タイプのE17口金と一般電球タイプのE26口金とがある。 The size of the bulb is a E26 cap of E17 cap and general bulb type compact bulb type. 本実施例の図5(b)に示すものにおいてはE17口金では絶縁部材24の外径は19.6mm、内径は15.2mmであり、E26口金では絶縁部材24の外径は30mm、内径は23.2mmである。 The outer diameter of the insulating member 24 in E17 cap in those shown in FIG. 5 (b) of the present example 19.6 mm, an inner diameter of 15.2 mm, an outer diameter of the insulating member 24 is E26 spinneret 30 mm, inner diameter it is 23.2mm. 外郭部材2のリング状の底面部やツバ部16aはこれに応じた大きさとなる。 A ring-shaped bottom portion and the flange portion 16a of the outer member 2 is the magnitude corresponding thereto. 3部材の面積が大きいほど伝熱効果が高くなり電球は大きくなる。 Bulbs increases the heat transfer effect the larger the area of ​​the third member is increased. 反対に3部材の面積が小さいほど電球は小さくなり伝熱効果は低くなる。 Thermal effects Den as bulbs decreases small area opposite to the third member is low.

図5(c)は図5(a)と外形状態は同一であるが、絶縁部材24と絶縁カバー26を一体で構成した絶縁離隔カバー部材27を用いた場合の構成である。 Although FIG. 5 (c) FIGS. 5 (a) and outline state are the same, a configuration in which an insulating separation cover member 27 where the insulating member 24 and the insulating cover 26 is integrally configured. 図5(c)のような構成とすることで構成部材を減らしてコスト低減するという効果と共に加工工程を簡略化できるという効果の2つの効果が見込める。 Figure 5 two effects structure and reduce the component by the effect of simplifying the processing step with the effect that cost reduction as (c) can be expected. 絶縁離隔カバー部材27の取り付けは例えば2つに分割した絶縁離隔カバー部材27を外郭部材2やツバ付口金16の外側から取り付け、熱や圧力等により圧着するという方法で行ってもよい。 Installing the insulating separation cover member 27 is mounted an insulating separation cover member 27 which is divided into two for example from the outside of the outer member 2 and Flanged cap 16 may be performed in a way that crimping by heat or pressure or the like.

また、上述したように外郭部材2とツバ付口金16間の沿面距離は1.6mm以上が必要であるという電気安全法令等(JIS規格:C6950−1)の制約条件がある。 Also, electrical safety laws that creepage distance between the outer member 2 and Flanged mouthpiece 16 as described above is required than 1.6 mm (JIS Standard: C6950-1) have constraints.

ただ沿面距離はツバ付口金16と絶縁部材24と外郭部材2とが絶縁離隔カバー部材27で覆われ、かつ内部に空気層が生じない場合は、上記制約条件に制限されることはない。 Just creepage distance and Flanged mouthpiece 16 and the insulating member 24 and the outer member 2 is covered with an insulating separation cover member 27, and when the air layer is not generated inside, but the invention is not limited to the above constraints.

また、図5(d)は図5(b)の外形状態と同一である。 Further, FIG. 5 (d) is the same as the outer shape state of FIG. 5 (b). 図5(b)と異なる点は、絶縁部材24と絶縁カバー26の代わりに図5(c)に示したものと同様の絶縁離隔カバー部材27を用いたところである。 FIG 5 (b) is different from, is where using a similar insulating separation cover member 27 to that shown in FIG. 5 (c) instead of the insulating member 24 and the insulating cover 26. これにより図5(b)と同様にデザイン性やコンパクト性を持つと共に、図5(c)と同様にコスト低減,加工工程も簡略化できるという効果が見込まれる。 Thus with similarly with design and compactness and FIG. 5 (b), the FIG. 5 (c) similarly to cost reduction, the effect of processing steps can be simplified expected.

図5(a)〜(d)に示す外郭部材(筐体)−口金接続構造でLED電球を製作することにより、LEDを搭載した基板4で生じた熱を、外郭部材2の載置部7,外郭部材2,外郭部材2の底面部2a,絶縁部材24または絶縁離隔カバー部材27,ツバ付口金16と伝え、ツバ付口金16からソケット30を介した熱伝導により効果的に逃がすと同時に、外郭部材2の表面から熱放射により逃がすことができる。 Figure 5 (a) ~ the outer member shown in (d) (housing) - By fabricating an LED bulb in cap connecting structure, the heat generated in the substrate 4 equipped with LED, mounting of the outer member 2 part 7 , outer member 2, the outer member 2 a bottom portion 2a, the insulating member 24 or the insulating separation cover member 27, reportedly Flanged cap 16, and at the same time effectively dissipated by the heat conduction through the socket 30 from Flanged cap 16, it can be released by thermal radiation from the surface of the outer member 2. これにより2つの冷却構造の効果が得られるため、電球全体の温度上昇を防止することが可能となる。 Since thereby the effect of the two cooling structures obtained, it is possible to prevent the temperature rise of the entire bulb.

また、図6(a)〜(d)は、図5(a)〜(d)と同様の構成であるが、外郭部材2とツバ付口金16間の離隔部の厚さが1.6mm以下で形成された場合の構成を示している。 Also, FIG. 6 (a) ~ (d) has the same structure as in FIG. 5 (a) ~ (d), the thickness of the spacing part between the outer member 2 and Flanged cap 16 is 1.6mm or less It shows a configuration in which in formed. 電気安全法令等(JIS規格:C6950−1)により、絶縁部材24と絶縁離隔カバー部材27の外郭部材2とツバ付口金16間の沿面距離は1.6mm以上が必要であるが、その厚さが維持できない可能性のある場合には、図6(a)〜(d)に記載のようにツバ付口金16のリング状の半径を短く構成することにより、ツバ付口金16と外郭部材2の間の沿面距離1.6mmを確保する構成を示している。 Electrical Safety laws (JIS Standard: C6950-1) by, although the creepage distance between the outer member 2 and the flange with cap 16 of insulating spaced cover member 27 and the insulating member 24 is required than 1.6 mm, a thickness there when that may not be maintained, by forming short ring-shaped radial flanged ferrule 16 as described in FIG. 6 (a) ~ (d), the flange with the die 16 and the outer member 2 It shows a structure to secure a creeping distance 1.6mm between. 上記の構造とすることにより、電気的な安全を確保することが可能となる。 By the above structure, it is possible to ensure electrical safety.

ただ沿面距離はツバ付口金16と絶縁部材24,外郭部材2が絶縁カバー26または絶縁離隔カバー部材27で覆われ、かつ内部に空気層が生じない場合は、上記制約条件に制限されることはない。 Just creepage distance from the insulating member 24 Flanged cap 16, the outer member 2 is covered with an insulating cover 26 or the insulating separation cover member 27, and when the air layer is not generated inside, be limited to the constraints Absent.

本実施例において、ツバ付口金16のツバ部16aをツバ付口金16の円筒部分の一端から外側に延伸するように設けられるとしたが、この限りではない。 In the present embodiment, although the flange portion 16a of the flange with the die 16 from one end of the cylindrical portion of the flange with the die 16 and is provided so as to extend outwardly, not limited to this. ツバ部16aは外郭部材2から絶縁部材24を介してツバ付口金16に熱が至る際に、熱抵抗が低くなるようにするために設けられている。 Flange part 16a when the heat reaches the Flanged cap 16 from outer member 2 via an insulating member 24, heat resistance is provided in order to be lower. そのためにはツバ部16aがツバ付口金16の円筒部分の一端から外側に延伸するように設けられる形状に限るものではなく、ツバ部16aが円筒部分の一端から内側に延伸するように設けられる構成や、ツバ部16aが円筒部分の内側と外側に係るように設けられる構成としてもよい。 Therefore the is not limited to the shape flange 16a is provided so as to extend outwardly from one end of the cylindrical portion of the flange with the die 16, the configuration flange 16a is provided so as to extend inwardly from one end of the cylindrical portion or it may be configured such that flange 16a is provided as according to the inner and outer cylindrical portions. この場合、外側に延伸するように設けた場合と同様の効果を奏することができる。 In this case, it is possible to achieve the same effect as in the case of providing to extend outwardly.

次に本発明の他の実施例について、図7〜図9を参照して説明する。 Next another embodiment of the present invention will be described with reference to FIGS. なお、この実施例2においても、実施例1と同一の構成要素については、同一の参照番号を付与しており、重複を避けるため、その詳細な説明は省略する。 Also in this second embodiment, the same components as in Example 1, has been given the same reference numerals, to avoid duplication, a detailed description thereof will be omitted.

図7は本実施例の外郭部材(筐体)−口金接続構造の詳細を説明する説明図である。 Figure 7 is the outer member (housing) of this embodiment - is an explanatory view illustrating details of the base connection structure. 図8は本発明の図7に示した部材の断面構成図である。 Figure 8 is a sectional view of a member shown in FIG. 7 of the present invention. 図9は本発明の外郭部材(筐体)−口金接続構造の第二の実施例の斜視図を示している。 Figure 9 is the outer member (housing) of the present invention - shows a perspective view of a second embodiment of the mouthpiece connecting structure. 図9においては図4で示したツバ付口金16の代用として、従来の口金部6に新たに付与する帽子形状の伝熱部材25を設けてツバ付口金16と同様の効果を狙ったものである。 As a substitute for Flanged mouthpiece 16 shown in FIG. 4 in FIG. 9, which was aimed at the same effect as Flanged cap 16 provided with a conventional cap portion 6 heat transfer member 25 of the hat shape to be newly applied to the is there.

伝熱部材25は、従来の口金部6の内側面にその外周面が接触する円筒部分25bと外郭部材2の口金部側のリング状の底面部2aと重複するように延伸するリング形状のツバ部25aを併せ持つ中空の帽子形状である。 Heat transfer member 25, flange ring shape extending so as to overlap the inner surface of the conventional metal caps 6 and the cylindrical portion 25b and the base part side of the outer member 2 a ring-shaped bottom portion 2a of the outer circumferential surface is in contact part 25a is a hollow hat shape having both. 伝熱部材25のツバ部25aと外郭部材2の口金部側のリング状の底面部2aとの間にリング状の絶縁部材24を設けた構造となっている。 It has a structure in which a ring-shaped insulating member 24 between the flange portion 25a and the base part side of the outer member 2 a ring-shaped bottom surface portion 2a of the heat transfer member 25.

図9に示した伝熱部材25を新たに設けることにより、これまでの口金部6の形状は変更する必要が無くなり、実施例1のツバ付口金16のように特殊な構造を用いないためコストが安い口金部6がそのまま利用可能となる。 The newly provided that the heat transfer member 25 shown in FIG. 9, which until the shape of the base part 6 of it is not necessary to change, the cost is not used a special structure as Flanged cap 16 of Example 1 the cap portion 6 as it is made available cheap.

図10(a)〜(d)に伝熱部材25を用いた場合の断面構成図を示す。 Figure 10 (a) ~ (d) shows a sectional view of a case of using the heat transfer member 25.

図10(a)〜(d)においては、伝熱部材25は口金部6の内側面と接触しており、また実施例1と同様に、伝熱部材25のツバ部25aは、外郭部材2の口金側の底面部2aと重複するような形状に構成される。 Figure in 10 (a) ~ (d), the heat transfer member 25 is in contact with the inner surface of the base portion 6, also in the same manner as in Example 1, the flange portion 25a of the heat transfer member 25, outer member 2 composed shaped to overlap the bottom portion 2a of the cap side.

さらに、伝熱部材25のツバ部25aと外郭部材2の底面部2aは絶縁部材24を介して接触する。 Further, the bottom surface portion 2a of the flange portion 25a and the outer member 2 of the heat transfer member 25 is in contact via an insulating member 24. 絶縁部材24は伝熱部材25のツバ部25aと外郭部材2の底面部2とにほぼ重複するようなリング状の部材で構成されている。 The insulating member 24 is constituted by a ring-shaped member so as to substantially overlap the bottom portion 2 of the flange portion 25a and the outer member 2 of the heat transfer member 25. 伝熱部材25のツバ部25aや外郭部材2の底面部2aと接触する絶縁部材24の面積は熱抵抗を低くするために、外郭部材2の底面部2aとほぼ同等程度の面積を有することが望ましく、かつ熱の伝導を良くするためには絶縁性を損なわない程度に最大限薄く構成されることが望ましい。 For the area of ​​the insulating member 24 in contact with the bottom surface portion 2a of the flange portion 25a and the outer member 2 of the heat transfer member 25 to reduce the thermal resistance, it has a substantially equal degree of area and the bottom surface portion 2a of the outer member 2 desirably, and in order to improve the conduction of heat is preferably constructed thinly maximally to the extent of not impairing the insulating property. さらに、伝熱部材25のツバ部25aと絶縁部材24と外郭部材2との間に空気層が生じると熱伝導が妨げられることから、前記3部材は可能な限り圧着して接触することが望ましい。 Further, it is desirable that the heat conducting the air layer is formed between the flange portion 25a of the heat transfer member 25 and the insulating member 24 and the outer member 2 is prevented, the three members are in contact and pressed as much as possible .

また、帽子形状の伝熱部材25は一体で形成されているが、サイズ調整を行うために切り欠いた場合や、加工,製造上の容易さから2つ以上の部材(例えば半円形状部材)等の複数の分割部材で構成された場合も同等の効果が期待できる。 Further, the heat transfer member 25 of the hat shape are formed integrally, and when cut out in order to perform resizing, machining, two or more members from the ease of manufacture (e.g., semicircular member) the same effect even when it is composed of a plurality of divided members etc. can be expected.

また、帽子形状の伝熱部材25はセラミックや樹脂等でも形成可能であるが、材料の熱伝導性・導電性・コスト・加工上の容易性や耐久性等で優位性を持つ金属材料で形成されることがより望ましい。 Further, the heat transfer member 25 of the hat shape is also possible to form a ceramic or resin, formed of a metallic material having a superior in ease and durability on thermal conductivity, electrical conductivity, cost and processability of the material is it is more desirable.

さらに絶縁部材24には、絶縁性を有すると共に高い熱伝導性を有する材料、たとえば窒化アルミ(AlN)や高熱伝導樹脂部材であるエラストマ等を用いることが望ましい。 Furthermore the insulating member 24, a material having a high thermal conductivity and having an insulating property, for example, it is desirable to use an elastomer such as a high heat conductive resin member and an aluminum nitride (AlN). なお、絶縁部材24の材料は、高い絶縁性と高い熱伝導性を兼ね備える材料であれば材料に限るものではない。 The material of the insulating member 24 is not limited to the material as long as the material combines high insulating properties and high thermal conductivity. さらに、材料に耐熱性,密着性等も兼ね備えることがあればより好ましい。 Further, heat-resistant material, more preferably if is possible to combine adhesiveness and the like. 絶縁部材24は金属,磁器,セラミックス、または樹脂材料等で構成される。 The insulating member 24 is made of metal, porcelain, ceramic or resin material.

また、上述したように絶縁部材24の厚さ、すなわち外郭部材2と帽子形状の伝熱部材25間の沿面距離は1.6mm以上が必要という電気安全法令等(JIS規格:C6950−1)の制約条件がある。 The thickness of the insulating member 24 as described above, i.e. electrical safety laws that creepage distance between the heat transfer member 25 of the outer member 2 and a hat shape must be at least 1.6 mm (JIS Standard: C6950-1) of there is a constraint.

ただ沿面距離は伝熱部材25と絶縁部材24,外郭部材2が完全に後述する絶縁カバー26で覆われ、かつ内部に空気層が生じない場合は、上記制約条件に制限されることはない。 Just Creepage heat transfer member 25 and the insulating member 24 is covered with an insulating cover 26 outer member 2 is described below completely and if the air layer is not generated inside, but the invention is not limited to the above constraints.

さらに、図10(a),(b)では実施例1に示したように外郭部材(筐体)−口金接続構造9において、外郭部材2と絶縁部材24と伝熱部材25の3部材の重複部分に人が触らないように絶縁カバー26が設けられている。 Further, FIG. 10 (a), the outer member as shown in (b) in Example 1 (housing) - in the mouthpiece connection structure 9, duplication of 3 members of the outer member 2 and the insulating member 24 and the heat transfer member 25 insulating cover 26 is provided so that a person does not touch the portion. 絶縁カバー26はABS樹脂等の絶縁性部材で構成されており、電球取り付け,取り外し時の安全性を確保するのに必要な部材となっている。 Insulating cover 26 is made of an insulating member such as ABS resin, and has a member that is necessary to ensure the bulb mounting, safety during removal. 絶縁カバー26の材料は絶縁性が確保されれば、材料に限るものではない。 If the material of the insulating cover 26 is insulating properties are secured, not limited to the material.

図10(a)は前記3部材の重複部分が熱抵抗を低く保つために最大限確保された場合のカバー状態であり、絶縁カバー26が外郭部材2より外側に少し突出した状態で構成されている。 10 (a) is a cover state when overlapping portions of the third member is maximally secured in order to keep low thermal resistance, it is constituted in a state where an insulating cover 26 is slightly protruded from the outer member 2 on the outside there. つまり図10(a)のように絶縁カバー26を設けた場合、外郭部材2の口金部側の外径は絶縁カバー26の外径よりも小さくなる。 That case in which the insulating cover 26 as shown in FIG. 10 (a), the outer diameter of the base portion side of the outer member 2 is smaller than the outer diameter of the insulation cover 26.

一方、図10(b)ではデザイン性やコンパクト性を重視した場合の外郭部材(筐体)−口金接続構造9を示しており、前記3部材の重複部分の面積が図10(a)に比較して少し小さくなっており、絶縁カバー26が外郭部材2の外周部分と段差が生じない状態になるように構成されている。 On the other hand, the outer member when an emphasis on the design and compactness FIG 10 (b) (housing) - compared to show a mouthpiece connecting structure 9, the area of ​​the overlapped portion of the third member in FIG. 10 (a) and has become a little smaller, the insulation cover 26 is an outer peripheral portion and the step of the outer member 2 is configured such that a state does not occur. つまり図10(b)のように絶縁カバー26を設けた場合、外郭部材2の口金部側の外径と絶縁カバー26の外径とは略同一となる。 That case in which the insulating cover 26 as shown in FIG. 10 (b), the is substantially identical outer diameter of the base part side of the outer member 2 and the outer diameter of the insulation cover 26.

ここで、電球の大きさは小型電球タイプのE17口金と一般電球タイプのE26口金とがある。 The size of the bulb is a E26 cap of E17 cap and general bulb type compact bulb type. 本実施例の図10(b)に示すものにおいてはE17口金では絶縁部材24の外径は19.6mm、内径は15.2mmであり、E26口金では絶縁部材24の外径は30mm、内径は23.2mmである。 The outer diameter of the insulating member 24 in E17 cap in those shown in FIG. 10 (b) of the present example 19.6 mm, an inner diameter of 15.2 mm, an outer diameter of the insulating member 24 is E26 spinneret 30 mm, inner diameter it is 23.2mm. 外郭部材2のリング状の底面部やツバ部25aはこれに応じた大きさとなる。 A ring-shaped bottom portion and the flange portion 25a of the outer member 2 is the magnitude corresponding thereto. 3部材の面積が大きいほど伝熱効果が高くなり電球は大きくなる。 Bulbs increases the heat transfer effect the larger the area of ​​the third member is increased. 反対に3部材の面積が小さいほど電球は小さくなり伝熱効果は低くなる。 Thermal effects Den as bulbs decreases small area opposite to the third member is low.

図10(c)は図10(a)と外形状態は同一であるが、絶縁部材24と絶縁カバー26を一体で構成した絶縁離隔カバー部材27を用いることにより、構成部材を減らしてコスト低減すると共に加工工程を簡略化できるという2つの効果が見込める構成を示している。 While FIG. 10 (c) Fig. 10 (a) and outline state are the same, by using an insulating separation cover member 27 which is integrally configured insulation member 24 and the insulating cover 26, to reduce costs by reducing the component It shows two effects can be expected structure that can simplify the working process with.

図10(d)は図10(b)の外形,構成において、絶縁離隔カバー部材27を用いたものであり、図10(b)と同様にデザイン性やコンパクト性を持つと共に、コスト低減,加工工程も簡略化できるという効果が見込まれる。 Figure 10 (d) are outline in FIG. 10 (b), the in the structure, which uses an insulating separation cover member 27, the same as with the design and compactness and FIG. 10 (b), the cost reduction, processability effect that step can be simplified expected.

図11(a)〜(d)は帽子形状の伝熱部材25の口金部6と接する部分である伝熱部材25の内周部が口金部6の外部に接するように形成した他の実施例を示している。 Figure 11 (a) ~ (d) are other embodiments that the inner peripheral portion of the heat transfer member 25 is a portion in contact with the base part 6 of the heat transfer member 25 is formed in contact with the outside of the base part 6 of the hat shape the shows. このように伝熱部材25が口金部6と外部で接続されることにより、加工及び密着性の確認がさらに簡単に行うことができるというメリットがある。 By thus heat transfer member 25 are connected by the base part 6 and the outside, there is a merit that confirmation processing and adhesion can be carried out more easily.

図11(a),(b)では図10(a),(b)と同様に外郭部材(筐体)−口金接続構造9において、外郭部材2と絶縁部材24と伝熱部材25の3部材の重複部分に人が触って感電しないように絶縁カバー26が設けられている。 Figure 11 (a), (b) in FIG. 10 (a), (b) similarly to the outer member (housing) - in the mouthpiece connection structure 9, 3 members of the outer member 2 and the insulating member 24 and the heat transfer member 25 insulation cover 26 so as not to electric shock by touching a person is provided in the overlapping part of. 絶縁カバー26はABS樹脂等の絶縁性部材で構成されており、電球取り付け,取り外し時の安全性を確保するのに必要な部材となっている。 Insulating cover 26 is made of an insulating member such as ABS resin, and has a member that is necessary to ensure the bulb mounting, safety during removal. 本実施例において、伝熱部材25は絶縁カバー26により全てが覆われておらず、絶縁部材24のリング状部分と伝熱部材25のツバ部25aの重複部分のみが覆われる構成となっている。 In this embodiment, the heat transfer member 25 has a structure not covered all the insulating cover 26, only the overlapping portion of the flange portion 25a of the ring-shaped portion and the heat transfer member 25 of the insulating member 24 is covered . これは通常の口金部の露出部分と同様の箇所が露出する構成となっているためである。 This is because the same parts as the exposed portion of the conventional cap portion is configured to be exposed. ただし、構成はこの限りではなく安全性を重視する場合は25を全て覆っても良い。 However, if you want to focus on safety rather than as long as this configuration may be covered all the 25. また、伝熱部材25の円筒部分25bの側面積の大きさは口金部への伝熱に影響し、側面積が大きいほど伝熱効果が高くなる。 The size of the lateral area of ​​the cylindrical portion 25b of the heat transfer member 25 affects the heat transfer to the base part, the heat transfer effect the larger the lateral area increases.

図11(a)は前記3部材の重複部分が熱抵抗を低く保つために最大限確保された場合のカバー状態であり、絶縁カバー26が外郭部材2より外側に少し飛び出した状態で構成されている。 11 (a) is a cover state when overlapping portions of the third member is maximally secured in order to keep low thermal resistance, it is constituted in a state where an insulating cover 26 is slightly jumped out from the outer member 2 on the outside there.

一方、図11(b)ではデザイン性やコンパクト性を重視した場合の外郭部材(筐体)−口金接続構造9を示しており、前記3部材の重複部分の面積が図11(b)に比較して少し小さくなっており、絶縁カバー26が外郭部材2の外周部分と段差が生じない状態になるように構成されている。 On the other hand, the outer member when an emphasis on the design and compactness FIG 11 (b) (housing) - compared to show a mouthpiece connecting structure 9, the area of ​​the overlapped portion of the third member in FIG. 11 (b) and has become a little smaller, the insulation cover 26 is an outer peripheral portion and the step of the outer member 2 is configured such that a state does not occur. つまり図11(b)のように絶縁カバー26を設けた場合、外郭部材2の口金部側の外径と絶縁カバー26の外径とは略同一となる。 That case in which the insulating cover 26 as in FIG. 11 (b), becomes substantially the same outer diameter of the base part side of the outer member 2 and the outer diameter of the insulation cover 26.

図11(c)は図11(a)と外形状態は同一であるが、絶縁部材24と絶縁カバー26を一体で構成した絶縁離隔カバー部材27を用いることにより、構成部材を減らしてコスト低減すると共に加工工程を簡略化できるという2つの効果が見込める構成を示している。 While FIG. 11 (c) Fig. 11 (a) and outline state are the same, by using an insulating separation cover member 27 which is integrally configured insulation member 24 and the insulating cover 26, to reduce costs by reducing the component It shows two effects can be expected structure that can simplify the working process with.

また、図11(d)は図11(b)の外形,構成において、絶縁離隔カバー部材27を用いたものであり、図11(b)と同様にデザイン性やコンパクト性を持つと共に、コスト低減,加工工程も簡略化できるという効果が見込まれる。 Further, FIG. 11 (d) are outline in FIG. 11 (b), in the configuration, which uses an insulating separation cover member 27, 11 together with the similarly with design and compactness and (b), cost reduction , the effect is expected that processing steps can be simplified.

図12(a)〜(d)は、図10(a)〜(d)と同様の構成であるが、外郭部材2と伝熱部材25間の離隔部の厚さ(沿面距離)が1.6mm以下で形成された場合の構成を示している。 Figure 12 (a) ~ (d) has the same structure as in FIG. 10 (a) ~ (d), the thickness of the spacing part between the outer member 2 and the heat transfer member 25 (creepage distance) is 1. It shows a configuration of a case where it is formed by 6mm or less. 既に述べたように、電気安全法令等(JIS規格:C6950−1)により、外郭部材2と伝熱部材25間の離隔部の厚さ(沿面距離)は1.6mm以上が必要であるが、その厚さが維持できない場合には、図12(a)〜(d)に記載のように帽子形状の伝熱部材25のリング状の半径を短く構成することにより、伝熱部材25と外郭部材2の間の距離1.6mmを確保する構成を示している。 As already mentioned, the electrical safety laws (JIS Standard: C6950-1), the thickness of the spacing part between the outer member 2 and the heat transfer member 25 (creepage distance) but is required than 1.6 mm, if the thickness can not be maintained, by forming short ring-shaped radial heat transfer member 25 hat shape as described in FIG. 12 (a) ~ (d), the heat transfer member 25 and the outer member It shows a structure to secure the distance 1.6mm between 2. 上記の構造とすることにより、電気的な安全を確保することが可能となる。 By the above structure, it is possible to ensure electrical safety.

ただ沿面距離は伝熱部材25,絶縁部材24と外郭部材2が完全に絶縁カバー26または絶縁離隔カバー部材27で覆われ、かつ内部に空気層が生じない場合は上記制約条件に制限されることはない。 Just Creepage heat transfer member 25, the insulating member 24 and the outer member 2 is completely covered with the insulation cover 26 or the insulating separation cover member 27, and it is when the air layer is not caused to be limited to the constraints within no.

本実施例において、伝熱部材25のツバ部25aを伝熱部材25の円筒部分25bの一端から外側に延伸するように設けられるとしたが、この限りではない。 In the present embodiment, although the flange portion 25a of the heat transfer member 25 from one end of the cylindrical portion 25b of the heat transfer member 25 and is provided so as to extend outwardly, not limited to this. ツバ部25aは外郭部材2から絶縁部材24,伝熱部材25を介して口金部6に熱が至る際に、熱抵抗が低くなるようにするために設けられている。 Flange portion 25a outer member 2 of an insulating member 24, when the heat reaches the mouthpiece 6 through the heat transfer member 25, the heat resistance is provided in order to be lower. そのためにはツバ部25aが伝熱部材25の円筒部分25bの一端から外側に延伸するように設けられる形状に限るものではなく、ツバ部25aが円筒部分25bの一端から内側に延伸するように設けられる構成や、ツバ部25aが円筒部分25bの内側と外側に係るように設けられる構成としても外側に延伸するように設けた場合と同様の効果を奏することができる。 Therefore the is not limited to the shape provided to the flange portion 25a is extended outward from one end of the cylindrical portion 25b of the heat transfer member 25, provided to the flange portion 25a is extended inwardly from one end of the cylindrical portion 25b configuration and which are, capable of flange 25a is the same effect as if also provided to extend outwardly a configuration provided as according to the inner and outer cylindrical portion 25b.

また、本実施例において、絶縁部材24を外郭部材2と伝熱部材25の間に設け、リング形状としたがこの限りではない。 Further, in this embodiment, the insulating member 24 provided between the outer member 2 and the heat transfer member 25 has a ring shape not limited. 絶縁部材24を設ける目的は外郭部材2に電気が伝わらないようにすることである。 The purpose of providing the insulating member 24 is to prevent transmitted electric in the outer member 2. そのため、絶縁部材24を外郭部材2と伝熱部材25の間に設けるのではなく、伝熱部材25と口金部6との間に設けても同じ効果を奏することができる。 Therefore, instead of providing between the outer member 2 and the heat transfer member 25 an insulating member 24, it can also achieve the same effect is provided between the heat transfer member 25 and the base part 6. その場合、絶縁部材24の形状は伝熱部材25の円筒部分25bを覆うような円筒形状となってもよいし、伝熱部材25と同様の帽子形状であってもよい。 In that case, the shape of the insulating member 24 may be a cylindrical shape to cover the cylindrical portion 25b of the heat transfer member 25 may be the same hat shape as the heat transfer member 25.

以上述べたように、図7〜図12に示す構成でLED電球を製作することにより、LED搭載部4で生じた熱を外郭部材2,絶縁部材24または絶縁離隔カバー部材27,伝熱部材25,口金部6,ソケット30を介した熱伝導により効果的に逃がすと同時に外郭部材2の表面から熱放射により逃がすという2つの冷却構造の効果が得られるため、電球全体の温度上昇を防止することが可能となる。 As described above, FIGS. 7 by fabricating an LED bulb in the configuration shown in 12, the outer member 2 a heat generated in the LED mounting portion 4, the insulating member 24 or the insulating separation cover member 27, the heat transfer member 25 since the base part 6, the effect of the two cooling structures that escape by heat radiation from the effective escape at the same time the outer member 2 surface by heat conduction through the socket 30 is obtained, preventing the temperature rise of the whole bulb it is possible.

さらに図1〜図12の構成で製作することにより、製品の加工においても外郭部材2と絶縁部材24とツバ付口金16のツバ部16a、または、外郭部材2と絶縁部材24と伝熱部材25と口金部6、絶縁離隔カバー部材27と口金部6の接触(圧着)において、電球外部における加工であるため、容易に圧力をかけることが可能であり、間隙の有無の確認も簡単に行えることが考えられる。 Furthermore, by fabricating the structure of FIGS. 12, flange portion 16a of the outer member 2 and the insulating member 24 and the flange with the mouthpiece 16 also in the processing of products or, outer member 2 and the insulating member 24 and the heat transfer member 25 mouthpiece 6 and, in contact with the insulating separation cover member 27 and the base portion 6 (crimping), since it is processed in the bulb outside, it is possible to easily apply pressure, confirmation of the presence or absence of the gap also be performed easily It can be considered. 従って、製作及び加工,確認も比較的容易で安価な構成である。 Therefore, fabrication and processing, confirmation is relatively easy and inexpensive construction.
