Description

電球形ランプLight bulb shaped lamp
　本発明は、電球形ランプに関し、特に、発光ダイオード（ＬＥＤ：Ｌｉｇｈｔ　Ｅｍｉｔｔｉｎｇ　Ｄｉｏｄｅ）等の半導体発光素子を備える電球形ランプに関する。 The present invention relates to a light bulb shaped lamp, and more particularly to a light bulb shaped lamp including a semiconductor light emitting element such as a light emitting diode (LED).
　半導体発光素子の一種であるＬＥＤは、従来の照明光源に比べて、小型、高効率および長寿命である。近年の省エネあるいは省資源に対する市場ニーズが追い風となり、フィラメントコイルを用いた従来の白熱電球の代替えとなる、ＬＥＤを用いた電球形ランプ（以下、単に「ＬＥＤ電球」ともいう）の需要が増加している。 An LED, which is a kind of semiconductor light emitting element, is smaller, more efficient, and has a longer life than a conventional illumination light source. Market demand for energy and resource savings in recent years has been a tailwind, and demand for bulb-type lamps using LEDs (hereinafter also simply referred to as “LED bulbs”) that can replace conventional incandescent bulbs using filament coils has increased. ing.
　ＬＥＤは、その温度が上昇するに伴って光出力が低下するとともに、寿命が短くなることが知られている。 It is known that the light output of the LED decreases as the temperature rises and the lifetime is shortened.
　特許文献１には、半球状のグローブと口金との間に金属製の筐体が設けられたＬＥＤ電球が開示されている。当該ＬＥＤ電球では、金属製の筐体により放熱性を高めることで、光源であるＬＥＤの、温度上昇の抑制（温度上昇による劣化の抑制）が図られる。 Patent Document 1 discloses an LED bulb in which a metal casing is provided between a hemispherical globe and a base.

　ここで、上記の特許文献１記載のＬＥＤ電球を含め、半導体発光素子を備える従来の電球形ランプでは、一般に、外部電源との接点となる口金は、螺合によって筐体と結合されている。 Here, in a conventional light bulb shaped lamp including a semiconductor light emitting element including the LED light bulb described in Patent Document 1, generally, a base serving as a contact point with an external power source is coupled to a housing by screwing.
　具体的には、筒状の筐体の一端の外周面にネジ山が設けられ、有底筒状の口金の内周面に当該ネジ山に対応するネジ溝が設けられており、口金の内部に、筐体の当該ネジ山の部分がネジ入れられることで、筐体に口金が取り付けられる。 Specifically, a screw thread is provided on the outer peripheral surface of one end of the cylindrical casing, and a screw groove corresponding to the screw thread is provided on the inner peripheral surface of the bottomed cylindrical base. In addition, the base is attached to the casing by screwing the thread portion of the casing.
　また、口金および筐体は、口金が筐体に取り付けられた状態において、口金の内周面と筐体のネジ山を備える端部とは、実質的に点または線で接触するように作製される。つまり、当該内周面と当該端部との間には隙間が存在する。これは、筐体への口金の取付を可能かつ容易にするためである。 Further, the base and the casing are manufactured so that the inner peripheral surface of the base and the end portion including the thread of the casing are substantially in contact with each other with a point or a line in a state where the base is attached to the casing. The That is, there is a gap between the inner peripheral surface and the end portion. This is to facilitate and facilitate the attachment of the base to the housing.
　つまり、仮にこのような隙間が全く存在しないように口金と筐体とを作製した場合、現実的には、口金と筐体とを螺合する際の口金と筐体との間の摩擦抵抗が大きく、当該螺合は不可能または困難である。また、この摩擦抵抗に抗して口金を筐体に取り付けようとした場合、例えば口金または筐体が変形する可能性がある。 In other words, if the base and the housing are made so that such a gap does not exist at all, in reality, the frictional resistance between the base and the housing when the base and the housing are screwed together is reduced. Large, the screwing is impossible or difficult. Moreover, when it is going to attach a nozzle | cap | die to a housing | casing against this frictional resistance, a nozzle | cap | die or a housing | casing may deform | transform, for example.
　一方で、電球形ランプには、例えば雨天での屋外の使用、または、水中での使用に耐えうる程度の防水性が要求される場合もある。この場合、例えば、電球形ランプの口金部分からの水分の浸入をどのようにして防ぐかが課題となる。 On the other hand, the bulb-type lamp may be required to have waterproofness enough to withstand outdoor use in rainy weather or underwater. In this case, for example, how to prevent moisture from entering from the cap portion of the light bulb shaped lamp becomes a problem.
　また、従来の電球形ランプにおいて、筐体には、複数の電子部品が収容されており、これら複数の電子部品のうちの高熱を発する電子部品が口金の近傍に位置する場合もある。 Further, in the conventional light bulb shaped lamp, a plurality of electronic components are accommodated in the casing, and the electronic component that generates high heat among the plurality of electronic components may be located in the vicinity of the base.
　本願発明者らは、このような状況を鑑み、ＬＥＤ電球等の従来の電球形ランプでは、筐体の口金が取り付けられる部分と、口金との間に隙間が存在し、これにより、電球形ランプにおける放熱性の向上が阻害されるという問題があるとの知見を得た。 In view of such a situation, the inventors of the present invention have a gap between a base to which a base of a housing is attached and a base in a conventional light bulb-type lamp such as an LED bulb, thereby It was found that there is a problem that the improvement of heat dissipation in is obstructed.
　また、本願発明者らは、口金と筐体との間の隙間の存在は、粉塵または水分等の異物が多く存在する空間内における、口金と筐体との螺合による異物の侵入に対する抑制効果が阻害されるという問題があるとの知見も得た。 In addition, the inventors of the present application show that the presence of a gap between the base and the housing is effective in suppressing the intrusion of foreign matter due to screwing between the base and the housing in a space where there are many foreign materials such as dust or moisture. It was also found that there is a problem that is disturbed.

And are used.
　これにより、半導体発光素子１１２から出射された青色光の一部が封止体１１３によって黄色光に波長変換され、当該波長変換による黄色光と変換されない青色光との混色により生成される白色光が発光モジュール１１０から放射される。 Thereby, a part of blue light emitted from the semiconductor light emitting device 112 is wavelength-converted into yellow light by the sealing body 113, and white light generated by color mixture of yellow light by the wavelength conversion and unconverted blue light is generated. Radiated from the light emitting module 110.
　［駆動回路］
　駆動回路（回路ユニット）１２０は、発光モジュール１１０の半導体発光素子１１２を点灯（発光）させるための点灯回路であって、発光モジュール１１０に所定の電力を供給する。 [Drive circuit]
The drive circuit (circuit unit) 120 is a lighting circuit for lighting (light emission) the semiconductor light emitting element 112 of the light emitting module 110, and supplies predetermined power to the light emitting module 110.
　例えば、駆動回路１２０は、一対のリード線１３０ｃ及び１３０ｄを介して口金１８０から供給される交流電力を直流電力に変換し、一対のリード線１３０ａ及び１３０ｂを介して当該直流電力を発光モジュール１１０に供給する。 For example, the drive circuit 120 converts AC power supplied from the base 180 via the pair of lead wires 130c and 130d into DC power, and the DC power is supplied to the light emitting module 110 via the pair of lead wires 130a and 130b. Supply.
　駆動回路１２０は、回路基板１２１と、回路基板１２１に接続された複数の回路素子（電子部品）１２２とを有する。 The drive circuit 120 includes a circuit board 121 and a plurality of circuit elements (electronic components) 122 connected to the circuit board 121.

　［口金］
　口金１８０は、駆動回路１２０に供給される電力を外部から受ける、筐体１６０の一端に備えられた部材である。 [Base]
The base 180 is a member provided at one end of the housing 160 that receives electric power supplied to the drive circuit 120 from the outside.
　具体的には、筒状の筐体１６０の、グローブ１４０の開口部１４１と接続された端部とは反対側の端部に、ネジ山を有する螺合部１６２が設けられており、螺合部１６２に口金１８０が螺合することで、口金１８０が筐体１６０に取り付けられている。 Specifically, a threaded portion 162 having a thread is provided at the end of the cylindrical housing 160 opposite to the end connected to the opening 141 of the globe 140. The base 180 is attached to the housing 160 by screwing the base 180 into the portion 162.
　なお、口金１８０は、例えば照明器具のソケットに取り付けられ、これにより、口金１８０は、電球形ランプ１００の点灯のための電力を、照明器具のソケットから受けることができる。 Note that the base 180 is attached to, for example, a socket of a lighting fixture, so that the base 180 can receive power for lighting the light bulb shaped lamp 100 from the socket of the lighting fixture.
　また、口金１８０は、照明器具に取り付けられた場合にソケットの内部に収容される部分に貫通孔を有している。この貫通孔により、筐体１６０および口金１８０の内部と外部との間の気体の流通が可能となり、その結果、例えば電解コンデンサ１２２ｃ等の部品が過度に高熱になることが抑制される。また、当該貫通孔は、照明器具に取り付けられた場合にソケットの内部に位置するため、当該貫通孔を介した水分等の異物の浸入は抑制される。 Further, the base 180 has a through hole in a portion accommodated in the socket when attached to the lighting fixture. This through-hole enables gas to flow between the inside and outside of the housing 160 and the base 180, and as a result, for example, parts such as the electrolytic capacitor 122c are prevented from becoming excessively hot. Moreover, since the said through-hole is located in the inside of a socket, when attached to a lighting fixture, the penetration | invasion of foreign materials, such as a water | moisture content, through the said through-hole is suppressed.
　また、本実施の形態の電球形ランプ１００では、円環部材２１０が配置された円環溝１６４に、口金１８０の円環状の端縁部が収容されている。 Further, in the light bulb shaped lamp 100 of the present embodiment, the annular edge of the base 180 is accommodated in the annular groove 164 in which the annular member 210 is arranged.

　なお、図２および図４では、口金１８０およびその近傍の構造概要を明確にするために、電解コンデンサ１２２ｃ等の部材（図１参照）の図示は省略している。 2 and 4, illustration of members (see FIG. 1) such as the electrolytic capacitor 122c is omitted in order to clarify the structure outline of the base 180 and its vicinity.
　また、図２に示す螺合軸１９０は、口金１８０と螺合部１６２との螺合における口金１８０の回転中心となる仮想的な軸である。 Further, the screwing shaft 190 shown in FIG. 2 is a virtual shaft serving as the rotation center of the base 180 when the base 180 and the screwing portion 162 are screwed together.
　図２～図４に示すように、本実施の形態における電球形ランプ１００では、口金１８０と筐体１６０との間に、円環部材２１０が配置される。 As shown in FIG. 2 to FIG. 4, in the light bulb shaped lamp 100 in the present embodiment, an annular member 210 is disposed between the base 180 and the housing 160.
　具体的には、筐体１６０における、ネジ山が形成された螺合部１６２の付け根部分に存在する段差部１６３に、円環溝１６４が設けられており、かつ、円環溝１６４の内部に円環部材２１０が配置されている。つまり、円環溝１６４に円環部材２１０が埋設されている。 Specifically, an annular groove 164 is provided in a stepped portion 163 that exists at the base of a threaded portion 162 in which a thread is formed in the housing 160, and the annular groove 164 is provided inside the annular groove 164. An annular member 210 is disposed. That is, the annular member 210 is embedded in the annular groove 164.
　また、円環溝１６４には、螺合部１６２と螺合した状態における口金１８０の円環状の端縁部１８５が収容されており、かつ、口金１８０の端縁部１８５と、円環溝１６４の内面との間に円環部材２１０が挟みこまれている。 Further, the annular groove 164 accommodates an annular end edge 185 of the base 180 in a state of being screwed with the threaded portion 162, and the end edge 185 of the base 180 and the annular groove 164. An annular member 210 is sandwiched between the inner surface of each of the members.
　本実施の形態の電球形ランプ１００は、この円環部材２１０を備えることで、口金１８０の端縁部１８５からの水分等の異物の浸入を抑制することができる。 The light bulb shaped lamp 100 according to the present embodiment includes the annular member 210 so that entry of foreign matter such as moisture from the end edge portion 185 of the base 180 can be suppressed.
　ここで、口金１８０の端縁部１８５からの水分等の異物の浸入を抑制するために、例えば、口金１８０と螺合部１６２とを螺合した後に、端縁部１８５と筐体１６０との隙間を埋めるように、端縁部１８５の端縁に沿って外側から硬化性の樹脂等のシール剤で塗り固めることも考えられる。 Here, in order to suppress entry of foreign matter such as moisture from the end edge portion 185 of the base 180, for example, after the base 180 and the screwing portion 162 are screwed together, the end edge portion 185 and the housing 160 are It is also conceivable to paint with a sealing agent such as a curable resin from the outside along the edge of the edge 185 so as to fill the gap.
　しかしながら、この場合、例えば、上記構成を有する電球形ランプを照明器具に取り付ける場合などに、口金１８０が螺合部１６２に対して回転した場合、その回転角度が僅かであっても、固化したシール剤の変形等によりシール剤による防水性が低下することが考えられる。 However, in this case, for example, when the bulb lamp having the above-described configuration is attached to a lighting fixture, when the base 180 rotates with respect to the screwing portion 162, the solidified seal even if the rotation angle is slight. It is conceivable that the waterproofness due to the sealant is reduced due to deformation of the agent.
　また、端縁部１８５と筐体１６０との境界の外周に樹脂を塗布することでシール部が形成された場合、当該シール部の外部への露出面積は大きいため、設置環境の変化（温度および湿度の変化等）の影響を受けやすい。つまり、設置環境の変化に起因するシール部の劣化が生じ易い。 In addition, when the seal portion is formed by applying a resin to the outer periphery of the boundary between the end edge portion 185 and the housing 160, the exposed area of the seal portion to the outside is large. Susceptible to changes in humidity). That is, the seal portion is likely to deteriorate due to a change in the installation environment.
　一方、円環部材２１０を備える電球形ランプ１００では、仮に口金１８０が螺合部１６２に対して回転した場合であっても、その回転角度が僅かであれば、円環部材２１０の弾性により、口金１８０の端縁部１８５と円環部材２１０との接触状態は維持される。 On the other hand, in the light bulb shaped lamp 100 including the annular member 210, even if the base 180 rotates with respect to the screwing portion 162, if the rotation angle is slight, the elasticity of the annular member 210 The contact state between the end edge 185 of the base 180 and the annular member 210 is maintained.
　また、円環部材２１０は、円環溝１６４に埋設されるため、外部への露出面積は非常に少なく、設置環境の変化に起因する円環部材２１０の劣化という問題も生じ難い。 Further, since the annular member 210 is embedded in the annular groove 164, the exposed area to the outside is very small, and the problem of deterioration of the annular member 210 due to a change in the installation environment hardly occurs.
　つまり、電球形ランプ１００における、円環部材２１０による水分の侵入抑制機能は、照明器具への取付作業または運搬時などに与えられる外力への耐性、および、環境変化に対する耐性が高いといえる。 That is, it can be said that the moisture intrusion suppression function by the annular member 210 in the light bulb shaped lamp 100 is highly resistant to external force applied during attachment to a lighting fixture or during transportation, and resistance to environmental changes.
　また、円環溝１６４の内部に設置された円環部材２１０が、上述のような水分の侵入に対する抑制効果を有することで、例えば、ＩＰ（Ｉｎｔｅｒｎａｔｉｏｎａｌ　Ｐｒｏｔｅｃｔｉｏｎ）規格に示されるいずれかの保護等級に対応した電球形ランプ１００の提供が可能となる。また、円環部材２１０による、水分の侵入に対する抑制果によって、電球形ランプ１００の延命化という効果も生じる。 In addition, the annular member 210 installed in the annular groove 164 has an effect of suppressing the intrusion of moisture as described above. The corresponding light bulb shaped lamp 100 can be provided. Moreover, the effect of prolonging the life of the light bulb shaped lamp 100 is also produced by the effect of suppressing the intrusion of moisture by the annular member 210.
　上述のように、本実施の形態における電球形ランプ１００では、円環溝１６４の内部に配置された円環部材２１０により、口金１８０の端縁部１８５からの水分の浸入を抑制することができる。また、電球形ランプ１００は、当該抑制の効果をさらに向上させるための要素を有してもよい。 As described above, in the light bulb shaped lamp 100 according to the present embodiment, the intrusion of moisture from the end edge portion 185 of the base 180 can be suppressed by the annular member 210 disposed inside the annular groove 164. . In addition, the light bulb shaped lamp 100 may include an element for further improving the suppression effect.
　例えば、円環溝１６４に挿入された状態の口金１８０の端縁部１８５が、樹脂等により封止されてもよい。 For example, the end edge 185 of the base 180 inserted into the annular groove 164 may be sealed with resin or the like.
　図５は、実施の形態１における電球形ランプ１００の円環部材２１０付近の断面の第１の例を示す図である。 FIG. 5 is a diagram illustrating a first example of a cross section near the annular member 210 of the light bulb shaped lamp 100 according to the first embodiment.
　図６は、実施の形態１における電球形ランプ１００の円環部材２１０付近の断面の第２の例を示す図である。 FIG. 6 is a diagram showing a second example of a cross section in the vicinity of the annular member 210 of the light bulb shaped lamp 100 according to the first embodiment.
　図５および図６に示すように、本実施の形態における電球形ランプ１００は、封止部材２２０を備えてもよい。 As shown in FIGS. 5 and 6, the light bulb shaped lamp 100 in the present embodiment may include a sealing member 220.
　図５に示す封止部材２２０は、少なくとも口金１８０の端縁部１８５の外周面を覆うように円環溝１６４に収容されている。 The sealing member 220 shown in FIG. 5 is accommodated in the annular groove 164 so as to cover at least the outer peripheral surface of the end edge portion 185 of the base 180.
　なお、封止部材２２０の素材としては、例えば、シリコーン樹脂等の樹脂であって、固化した後でも所定の柔軟性を維持できる樹脂が採用される。 In addition, as a material of the sealing member 220, for example, a resin such as a silicone resin, which can maintain a predetermined flexibility even after being solidified is employed.
　具体的には、螺合部１６２と口金１８０との螺合が完了し、口金１８０の端縁部１８５が円環部材２１０に当接した状態で、シリコーン樹脂等の樹脂が円環溝１６４に流し込まれることで、端縁部１８５の外周面を覆う封止部材２２０が形成される。 Specifically, when the screwing of the screwing part 162 and the base 180 is completed and the end edge part 185 of the base 180 is in contact with the annular member 210, a resin such as silicone resin enters the annular groove 164. The sealing member 220 which covers the outer peripheral surface of the edge part 185 is formed by being poured.
　これにより、まず、封止部材２２０によって、端縁部１８５からの水分等の異物の浸入が抑制される。また、仮に、例えば封止部材２２０の経年劣化に起因して、水分が封止部材２２０を越えた場合であっても、円環部材２１０によって、当該水分の筐体１６０の内部への侵入は抑制される。 Thereby, first, the sealing member 220 suppresses intrusion of foreign matters such as moisture from the end edge portion 185. In addition, even if the moisture exceeds the sealing member 220 due to, for example, aging of the sealing member 220, the annular member 210 prevents the moisture from entering the housing 160. It is suppressed.
　また、螺合部１６２と口金１８０とを螺合させる前に、円環部材２１０の上からシリコーン樹脂等の樹脂を円環溝１６４に流し込み、当該樹脂が固化する前に、螺合部１６２と口金１８０とを螺合させてもよい。 In addition, before screwing the threaded portion 162 and the base 180, a resin such as silicone resin is poured into the annular groove 164 from above the annular member 210, and before the resin is solidified, the threaded portion 162 and The base 180 may be screwed together.
　その結果、例えば、図６に示すように、端縁部１８５の内方にも封止部材２２０の一部が形成されるため、封止部材２２０による、水分の筐体１６０の内部への侵入に対する抑制効果が向上する。 As a result, for example, as shown in FIG. 6, a part of the sealing member 220 is also formed inside the end edge portion 185, so that moisture enters the inside of the housing 160 by the sealing member 220. The suppression effect with respect to is improved.
　ここで、本実施の形態の封止部材２２０は、図５および図６に示すように、円環溝１６４に収容された状態で電球形ランプ１００に備えられる。そのため、例えば口金１８０の端縁部１８５と筐体１６０との境界の外周に樹脂を塗布することでシール部を形成した場合と比較すると、封止部材２２０外部への露出面積は、当該シール部の外部への露出面積よりも低く抑えられる。 Here, as shown in FIGS. 5 and 6, the sealing member 220 of the present embodiment is provided in the light bulb shaped lamp 100 in a state of being accommodated in the annular groove 164. Therefore, for example, compared with the case where the seal portion is formed by applying resin to the outer periphery of the boundary between the end edge portion 185 of the base 180 and the casing 160, the exposed area to the outside of the sealing member 220 is the seal portion. It can be kept lower than the exposed area to the outside.
　つまり、封止部材２２０は、設置環境の変化を受けにくい態様で電球形ランプ１００に備えられており、これにより、封止部材２２０における設置環境の変化に起因する経年劣化が抑制される。 That is, the sealing member 220 is provided in the light bulb shaped lamp 100 in a manner that is less susceptible to changes in the installation environment, thereby suppressing aging deterioration due to a change in the installation environment in the sealing member 220.
　また、図７および図８に示すように、口金１８０の端縁部１８５は、口金１８０が螺合部１６２と螺合した状態において、円環部材２１０の外周面の少なくとも一部を覆うように設けられてもよい。 Further, as shown in FIGS. 7 and 8, the end edge portion 185 of the base 180 covers at least a part of the outer peripheral surface of the annular member 210 when the base 180 is screwed with the screwing portion 162. It may be provided.
　図７は、実施の形態１における電球形ランプ１００の円環部材２１０付近の断面の第３の例を示す断面図である。 FIG. 7 is a cross-sectional view showing a third example of a cross section near the annular member 210 of the light bulb shaped lamp 100 in the first embodiment.
　図８は、実施の形態１における電球形ランプ１００の円環部材２１０付近の断面の第４の例を示す断面図である。 FIG. 8 is a cross-sectional view showing a fourth example of a cross section near the annular member 210 of the light bulb shaped lamp 100 in the first embodiment.
　例えば、図７に示すように、口金１８０の端縁部１８５ａを、円環部材２１０を抱持するように内側に屈曲または湾曲した形状に形成する。これにより、口金１８０と円環部材２１０との接触面積を増加させることができる。 For example, as shown in FIG. 7, the end edge portion 185a of the base 180 is formed in a shape bent or curved inward so as to hold the annular member 210. Thereby, the contact area of the nozzle | cap | die 180 and the annular member 210 can be increased.
　その結果、口金１８０と円環部材２１０との間からの水分の浸入に対する抑制効果が向上する。 As a result, the effect of suppressing the ingress of moisture from between the base 180 and the annular member 210 is improved.
　また、図８に示すように、口金１８０の端縁部１８５ｂは、端縁部１８５ｂによって形成される開口に近づくに従って口径が大きくなるよう形成されていることで、円環部材２１０の外周面の少なくとも一部を覆ってもよい。 Further, as shown in FIG. 8, the end edge portion 185 b of the base 180 is formed to have a larger diameter as it approaches the opening formed by the end edge portion 185 b, so that the outer peripheral surface of the annular member 210 is formed. You may cover at least one part.
　この構成によれば、図８に示すように、口金１８０と螺合部１６２とが螺合されることで、弾性を有する円環部材２１０は、端縁部１８５ｂによって、円環溝１６４の、Ｘ軸方向に平行な内面とＺ軸に平行な内面との双方に押圧される。 According to this configuration, as shown in FIG. 8, the base 180 and the threaded portion 162 are screwed together, so that the elastic annular member 210 is formed by the end edge portion 185 b of the annular groove 164. It is pressed by both the inner surface parallel to the X-axis direction and the inner surface parallel to the Z-axis.
　これにより、円環部材２１０と円環溝１６４の内面との密着性が向上し、その結果、円環溝１６４の内面と円環部材２１０との間からの水分の浸入に対する抑制効果が向上する。 As a result, the adhesion between the annular member 210 and the inner surface of the annular groove 164 is improved, and as a result, the effect of suppressing moisture intrusion from between the inner surface of the annular groove 164 and the annular member 210 is improved. .
　また、円環溝１６４および円環部材２１０の断面形状（Ｚ軸に平行な平面における断面形状、以下同じ）は、例えば図２等に示されるような矩形でなくてもよい。 Further, the cross-sectional shapes of the annular groove 164 and the annular member 210 (the cross-sectional shape in a plane parallel to the Z axis, hereinafter the same) may not be a rectangle as shown in FIG.
　図９は、断面形状が曲線で構成された円環溝１６４ａおよび円環部材２１０ａの断面の一例を示す図である。 FIG. 9 is a diagram showing an example of a cross section of the annular groove 164a and the annular member 210a whose cross-sectional shape is a curve.
　図１０は、断面形状がＶ字状である円環溝１６４ｂおよび円環部材２１０ｂの断面の一例を示す図である。 FIG. 10 is a diagram showing an example of a cross section of the annular groove 164b and the annular member 210b having a V-shaped cross section.
　電球形ランプ１００は、例えば図９に示すように、断面形状が曲線で構成された円環溝１６４ａおよび円環部材２１０ａを備えてもよい。 For example, as shown in FIG. 9, the light bulb shaped lamp 100 may include an annular groove 164a and an annular member 210a having a curved cross-sectional shape.
　また、電球形ランプ１００は、例えば図１０に示すように、断面形状が曲線で構成された円環溝１６４ｂおよび円環部材２１０ｂを備えてもよい。 Further, as shown in FIG. 10, for example, the light bulb shaped lamp 100 may include an annular groove 164b and an annular member 210b having a curved cross-sectional shape.
　つまり、電球形ランプ１００が備える円環溝および円環部材の断面形状に特に限定はない。なお、円環溝の断面形状と円環部材の断面形状とを同一または近似にすることで、円環部材と円環溝の内面との密着性を向上させることができる。 That is, there is no particular limitation on the cross-sectional shape of the annular groove and the annular member provided in the light bulb shaped lamp 100. In addition, the adhesiveness of an annular member and the inner surface of an annular groove can be improved by making the cross-sectional shape of an annular groove and the cross-sectional shape of an annular member the same or approximate.
　また、螺合部１６２に螺合した状態の口金１８０を筐体１６０に対して固定する手法に特に限定はない。例えば、口金１８０が螺合部１６２に螺合した状態で口金１８０を径方向にかしめることで、口金１８０を筐体１６０に固定してもよい。 In addition, there is no particular limitation on the method for fixing the base 180 that is screwed to the screwing portion 162 to the housing 160. For example, the base 180 may be fixed to the housing 160 by caulking the base 180 in the radial direction in a state where the base 180 is screwed to the screwing portion 162.
　また、上記のかしめに代えてまたは加えて、例えば筐体１６０が、口金１８０を筐体１６０に対して固定する構成を備えてもよい。 Further, instead of or in addition to the above-described caulking, for example, the housing 160 may be configured to fix the base 180 to the housing 160.
　図１１は、実施の形態１における電球形ランプ１００が係合部２３０を備える場合の円環部材２１０付近の断面を示す断面図である。 FIG. 11 is a cross-sectional view showing a cross section in the vicinity of the annular member 210 when the light bulb shaped lamp 100 according to the first embodiment includes the engaging portion 230.
　例えば図１１に示すように、電球形ランプ１００は、円環溝１６４の内面に突設された係合部２３０であって、端縁部１８５ｃと係合することで、円環溝１６４の内方に収容された端縁部１８５ｃの、円環溝１６４の外方への移動を規制する係合部２３０を備えてもよい。 For example, as shown in FIG. 11, the light bulb shaped lamp 100 is an engaging portion 230 protruding from the inner surface of the annular groove 164, and is engaged with the end edge portion 185 c, thereby There may be provided an engaging portion 230 for restricting the outward movement of the annular groove 164 of the end edge portion 185c accommodated in the direction.
　なお、係合部２３０は、例えば、円環溝１６４の内面において周方向に１以上設けられる。また、係合部２３０は、図１１に示すように、円環溝１６４の開口に近づくほど螺合軸１９０（図２参照）から遠ざかるように傾いた面を有していることで、口金１８０が螺合部１６２に螺合する際に、端縁部１８５ｃが係合部２３０を越え易くなっている。 Note that one or more engaging portions 230 are provided in the circumferential direction on the inner surface of the annular groove 164, for example. Further, as shown in FIG. 11, the engaging portion 230 has a surface that is inclined so as to move away from the screwing shaft 190 (see FIG. 2) as it approaches the opening of the annular groove 164. When the threaded portion 162 is screwed to the threaded portion 162, the end edge portion 185 c is likely to exceed the engaging portion 230.
　また、図１１に示ように、端縁部１８５ｃが、返し部１８５ｄを有することで、係合部２３０を越えて、円環溝１６４の内方に収容された端縁部１８５ｃが、円環溝１６４から抜け出し難い構造となっている。 Further, as shown in FIG. 11, the end edge portion 185 c has the return portion 185 d, so that the end edge portion 185 c accommodated inside the annular groove 164 beyond the engagement portion 230 is The structure is difficult to escape from the groove 164.
　なお、係合部２３０と端縁部１８５ｃとの係合の態様は、図１１に示す態様に限定されない。例えば、係合部２３０と端縁部１８５ｃとは、口金１８０が螺合部１６２に螺合する際の口金１８０の回転を許容し、かつ、反対方向の回転を困難とするように係り合う構造であってもよい。 In addition, the aspect of engagement with the engaging part 230 and the edge part 185c is not limited to the aspect shown in FIG. For example, the engaging portion 230 and the end edge portion 185c allow the base 180 to rotate when the base 180 is screwed into the screwing portion 162, and engage with each other so that rotation in the opposite direction is difficult. It may be.
　つまり、図１１では、係合部２３０と端縁部１８５ｃとは、螺合軸１９０に平行な方向に係り合っている。しかし、係合部２３０と端縁部１８５ｃとは、螺合軸１９０に平行な方向に係り合うことに代えてまたは加えて、螺合軸１９０を中心とした周方向に係り合ってもよい。 That is, in FIG. 11, the engaging portion 230 and the end edge portion 185 c are engaged in a direction parallel to the screwing shaft 190. However, the engaging portion 230 and the end edge portion 185 c may be engaged in the circumferential direction around the screwing shaft 190 instead of or in addition to being engaged in a direction parallel to the screwing shaft 190.
　このように、電球形ランプ１００は、係合部２３０を備えることで、例えば口金１８０に、口金１８０の筐体１６０への固定のためのかしめに適した部分がない場合であっても、口金１８０と筐体１６０との結合状態の安定性の確保が可能となる。 Thus, the light bulb shaped lamp 100 is provided with the engaging portion 230, so that, for example, even when the base 180 does not have a portion suitable for caulking for fixing the base 180 to the housing 160, It is possible to ensure the stability of the coupled state between 180 and the housing 160.
　なお、図７～図１１のそれぞれに示される円環溝１６４に、図５および図６を用いて説明した封止部材２２０が配置されてもよい。 Note that the sealing member 220 described with reference to FIGS. 5 and 6 may be disposed in the annular groove 164 shown in each of FIGS.
　これにより、電球形ランプ１００における、口金１８０と螺合部１６２との隙間からの水分の浸入に対する抑制効果がさらに向上する。 Thereby, in the light bulb shaped lamp 100, the effect of suppressing the ingress of moisture from the gap between the base 180 and the screwing portion 162 is further improved.
　また、例えば、図７（図８）を用いて説明した、円環部材２１０の外周面の少なくとも一部を覆うように設けられた端縁部１８５ａ（１８５ｂ）に係合するように、係合部２３０が円環溝１６４の内面に突設されていてもよい。 Further, for example, the engagement is performed so as to engage with the edge portion 185a (185b) provided so as to cover at least a part of the outer peripheral surface of the annular member 210 described with reference to FIG. 7 (FIG. 8). The part 230 may protrude from the inner surface of the annular groove 164.
　この場合、端縁部１８５ａ（１８５ｂ）に、返し部１８５ｄ（図１１参照）のような、端縁部１８５ａ（１８５ｂ）が、係合部２３０と安定的に係り合うための部分を設けてもよい。 In this case, the end edge portion 185a (185b) may be provided with a portion such as the return portion 185d (see FIG. 11) for the end edge portion 185a (185b) to stably engage with the engaging portion 230. Good.
　これにより、電球形ランプ１００における、口金１８０と螺合部１６２との隙間からの水分の浸入に対する抑制効果が向上するとともに、口金１８０と筐体１６０との結合状態の安定性の確保が可能となる。 Thereby, in the light bulb shaped lamp 100, the effect of suppressing the ingress of moisture from the gap between the base 180 and the screwing portion 162 is improved, and it is possible to ensure the stability of the coupling state between the base 180 and the housing 160. Become.
　（実施の形態２）
　次に、実施の形態２における電球形ランプ１０１の構成概要について、図１２を用いて説明する。 (Embodiment 2)
Next, a configuration outline of the light bulb shaped lamp 101 in the second embodiment will be described with reference to FIG.
　図１２は、実施の形態２における電球形ランプ１０１の断面図である。なお、図１２において、駆動回路１２０については断面図ではなく側面図である。 FIG. 12 is a cross-sectional view of the light bulb shaped lamp 101 in the second embodiment. In FIG. 12, the drive circuit 120 is not a sectional view but a side view.
　図１に示すように、本実施の形態に係る電球形ランプ１０１は、実施の形態１における電球形ランプ１００と同じく、電球形蛍光灯または白熱電球の代替品となる電球形ＬＥＤランプである。 As shown in FIG. 1, a light bulb shaped lamp 101 according to the present embodiment is a light bulb shaped LED lamp that is a substitute for a light bulb shaped fluorescent lamp or an incandescent light bulb, like the light bulb shaped lamp 100 in the first embodiment.
　本実施の形態に係る電球形ランプ１０１は、光源としての発光モジュール１１０と、発光モジュール１１０に所定の電力を供給するための駆動回路１２０と、駆動回路１２０を内部に収容する筐体１６０とを備える。 The light bulb shaped lamp 101 according to the present embodiment includes a light emitting module 110 as a light source, a drive circuit 120 for supplying predetermined power to the light emitting module 110, and a housing 160 that houses the drive circuit 120 therein. Prepare.
　本実施の形態における電球形ランプ１０１は、さらに、開口部１４１を有し、発光モジュール１１０を覆う中空のグローブ１４０と、外部から電力を受ける口金１８０とを備える。なお、本実施の形態における電球形ランプ１０１は、グローブ１４０と筐体１６０と口金１８０とによって外囲器が構成されている。 The light bulb shaped lamp 101 in the present embodiment further includes a hollow globe 140 having an opening 141 and covering the light emitting module 110, and a base 180 for receiving electric power from the outside. In the light bulb shaped lamp 101 in the present embodiment, an envelope is configured by the globe 140, the housing 160, and the base 180.
　なお、実施の形態２における電球形ランプ１０１が備える、筐体１６０、グローブ１４０、発光モジュール１１０、駆動回路１２０、および口金１８０のそれぞれの基本的な構成は、実施の形態１における電球形ランプ１０１が備える、筐体１６０、グローブ１４０、発光モジュール１１０、駆動回路１２０、および口金１８０のそれぞれの基本的な構成と同一である。 The basic configuration of the casing 160, the globe 140, the light emitting module 110, the drive circuit 120, and the base 180 included in the light bulb shaped lamp 101 according to the second embodiment is the same as that of the light bulb shaped lamp 101 according to the first embodiment. Are the same as the basic configurations of the housing 160, the globe 140, the light emitting module 110, the drive circuit 120, and the base 180.
　そのため、これら筐体１６０等の基本的な構成についての説明は省略し、実施の形態２の特徴的な構成について説明する。 Therefore, description of the basic configuration of the casing 160 and the like will be omitted, and the characteristic configuration of the second embodiment will be described.
　具体的には、実施の形態２の電球形ランプ１０１では、口金１８０の内周面と螺合部１６２との間に、口金１８０および螺合部１６２の双方と接触するように配置された介在部材２００が備えられている。 Specifically, in the light bulb shaped lamp 101 of the second embodiment, the interposition disposed between the inner peripheral surface of the base 180 and the screwing part 162 so as to come into contact with both the base 180 and the screwing part 162. A member 200 is provided.
　以下、介在部材２００、および、電球形ランプ１０１における介在部材２００の周辺の構造を中心に説明する。 Hereinafter, the structure around the interposed member 200 and the interposed member 200 in the light bulb shaped lamp 101 will be mainly described.
　［介在部材］
　介在部材２００は、例えば、螺合部１６２に樹脂等を塗布することで得られる薄膜状の部材であり、少なくとも厚み方向の柔軟性を備えた部材である。 [Intervening member]
The interposition member 200 is, for example, a thin film-like member obtained by applying resin or the like to the screwing portion 162, and is a member having at least flexibility in the thickness direction.
　つまり、螺合部１６２と口金１８０とが螺合する場合に、口金１８０の内周面と螺合部１６２との間において、場所ごとに厚みを変えるように変形する。 That is, when the screwing portion 162 and the base 180 are screwed together, the thickness is changed between the inner peripheral surface of the base 180 and the screwing portion 162 so as to change the thickness for each place.
　なお、介在部材２００の素材としては、例えば、アクリルフォーム等の樹脂材料が採用される。 In addition, as a raw material of the interposed member 200, resin materials, such as an acrylic foam, are employ | adopted, for example.
　図１３は、実施の形態２における電球形ランプ１０１の口金１８０部分の断面を示す断面図である。 FIG. 13 is a cross-sectional view showing a cross section of the cap portion 180 of the light bulb shaped lamp 101 in the second embodiment.
　図１４は、図１３におけるＡ－Ａ断面を示す断面図である。 FIG. 14 is a cross-sectional view showing an AA cross section in FIG.
　なお、図１３および図１４では、口金１８０と螺合部１６２のとの構造概要を明確にするために、電解コンデンサ１２２ｃ等の他の部材（図１２参照）の図示は省略している。 In FIGS. 13 and 14, the illustration of other members (see FIG. 12) such as the electrolytic capacitor 122c is omitted in order to clarify the structural outline of the base 180 and the screwing portion 162.
　図１３に示すように、螺合部１６２と口金１８０との間の距離は、口金１８０と螺合部１６２との螺合における口金１８０の回転中心となる仮想的な軸である螺合軸１９０に平行な方向において均一ではない。 As shown in FIG. 13, the distance between the screwing part 162 and the base 180 is a screwing shaft 190 that is a virtual axis that becomes the rotation center of the base 180 in the screwing of the base 180 and the screwing part 162. Is not uniform in the direction parallel to
　また、図１４に示すように、螺合部１６２と口金１８０との間の距離は、螺合部１６２の周方向においても均一ではない。 Further, as shown in FIG. 14, the distance between the screwing portion 162 and the base 180 is not uniform in the circumferential direction of the screwing portion 162.
　しかしながら、本実施の形態の電球形ランプ１０１では、上述のように柔軟性を有する薄膜状の介在部材２００を、螺合部１６２と口金１８０の内周面との間に配置される。これにより、介在部材２００がない場合に、口金１８０の内周面と螺合部１６２との間に生じる隙間が、介在部材２００によって実質的に埋められる。 However, in the light bulb shaped lamp 101 of the present embodiment, the thin film-like interposition member 200 having flexibility as described above is disposed between the screwing portion 162 and the inner peripheral surface of the base 180. Thereby, when there is no interposition member 200, a gap generated between the inner peripheral surface of the base 180 and the screwing portion 162 is substantially filled with the interposition member 200.
　ここで、上述の駆動回路１２０に備えられた複数の回路素子１２２のうち、最も背の高い電解コンデンサ１２２ｃの一部は、筐体１６０内において、口金１８０の内部に相当する空間（螺合部１６２の内方の空間）に配置されている（図１２参照）。また、電解コンデンサ１２２ｃは、駆動回路１２０の動作時において、例えば８０℃程度の高温を発する。 Here, among the plurality of circuit elements 122 provided in the drive circuit 120 described above, a part of the tallest electrolytic capacitor 122c is a space (screwed portion) corresponding to the inside of the base 180 in the housing 160. 162 (inner space) (see FIG. 12). Further, the electrolytic capacitor 122c generates a high temperature of, for example, about 80 ° C. during the operation of the drive circuit 120.
　このような状況において、本実施の形態の電球形ランプ１０１では、筐体１６０の螺合部１６２と口金１８０との間に、これらの双方に接する介在部材２００が配置されている。 In such a situation, in the light bulb shaped lamp 101 of the present embodiment, the interposition member 200 in contact with both of them is disposed between the screwing portion 162 of the housing 160 and the base 180.
　そのため、筐体１６０の内部の熱を、口金１８０を介して効率よく外部に放出することができ、これにより、電球形ランプ１０１全体としての放熱性は向上する。その結果、例えば、半導体発光素子１１２を延命化することができる。 Therefore, the heat inside the housing 160 can be efficiently released to the outside through the base 180, and as a result, the heat dissipation of the light bulb shaped lamp 101 as a whole is improved. As a result, for example, the life of the semiconductor light emitting device 112 can be extended.
　また、本実施の形態では、介在部材２００は、本実施の形態では、口金１８０および螺合部１６２の螺合軸１９０に交差する少なくとも一つの断面において、口金１８０の内周面と螺合部１６２との間の空間を全周において埋めるように配置されている。 Further, in the present embodiment, the interposition member 200 has a threaded portion and an inner peripheral surface of the base 180 in at least one cross section that intersects the threaded shaft 190 of the base 180 and the threaded portion 162 in the present embodiment. It arrange | positions so that the space between 162 may be filled up in a perimeter.
　例えば、図１４に示すように、螺合軸１９０に垂直な一つの断面である、Ａ－Ａ断面では、螺合部１６２が有するネジ山および口金１８０が有するネジ溝がらせん状であるために、螺合部１６２と口金１８０との間の距離は均一ではない。 For example, as shown in FIG. 14, in the AA cross section, which is one cross section perpendicular to the screwing shaft 190, the screw thread of the screwing portion 162 and the screw groove of the base 180 are spiral. The distance between the screwing portion 162 and the base 180 is not uniform.
　しかし、介在部材２００は、柔軟性を有していることで、当該断面において、口金１８０の内周面と螺合部１６２との間の空間を全周において埋めるように電球形ランプ１０１に備えられている。 However, the interposition member 200 has flexibility, so that the light bulb shaped lamp 101 is provided so that the space between the inner peripheral surface of the base 180 and the screwing portion 162 is filled in the entire circumference in the cross section. It has been.
　そのため、例えば、口金１８０部分における気密性が向上し、口金１８０の端縁部１８６から、筐体１６０の内部への、粉塵および水分等の異物の侵入を実質的に防止することが可能となる。 Therefore, for example, the air tightness in the base 180 portion is improved, and it is possible to substantially prevent foreign matters such as dust and moisture from entering the housing 160 from the end edge portion 186 of the base 180. .
　また、介在部材２００がない場合と比較すると、介在部材２００によって、口金１８０と螺合部１６２との螺合による、螺合部１６２から口金１８０への圧力が分散される。 Further, as compared with the case where there is no interposition member 200, the pressure from the screwing portion 162 to the base 180 due to the screwing of the base 180 and the screwing portion 162 is dispersed by the interposition member 200.
　これにより、例えば、口金１８０の変形を抑制しつつ、口金１８０と螺合部１６２と螺合におけるトルクを増加させることができる。簡単に言うと、口金１８０と螺合部１６２との結合力を向上させることができる。 Thereby, for example, the torque at the base 180, the screwing portion 162, and the screwing can be increased while suppressing the deformation of the base 180. In short, the coupling force between the base 180 and the screwing portion 162 can be improved.
　また、言い換えると、口金１８０の肉厚を薄くした場合であっても、口金１８０と螺合部１６２とをしっかりと螺合させることが可能となる。 In other words, even when the thickness of the base 180 is reduced, the base 180 and the screwing portion 162 can be firmly screwed together.
　また、介在部材２００が、上述のような異物の侵入の防止効果を有することで、例えば、電球形ランプ１０１の延命化以外にも、例えば、ＩＰ（Ｉｎｔｅｒｎａｔｉｏｎａｌ　Ｐｒｏｔｅｃｔｉｏｎ）規格に示されるいずれかの保護等級に対応した電球形ランプ１０１の提供が可能となる。 Further, since the interposition member 200 has an effect of preventing the intrusion of foreign matter as described above, for example, in addition to extending the life of the light bulb shaped lamp 101, for example, any protection shown in the IP (International Protection) standard The light bulb shaped lamp 101 corresponding to the grade can be provided.
　ここで、口金１８０と螺合部１６２との間からの、筐体１６０の内部への異物の侵入を防止するために、例えば、エラストマー（ｅｌａｓｔｏｍｅｒ）等の弾性を有する材料で構成された環状部材２１１を、口金１８０の端縁部１８６と、筐体１６０との間に配置してもよい。 Here, in order to prevent foreign matter from entering the inside of the housing 160 from between the base 180 and the screwing portion 162, for example, an annular member made of an elastic material such as an elastomer. 211 may be disposed between the edge 186 of the base 180 and the housing 160.
　以下、実施の形態２における環状部材２１１および電球形ランプ１０１における配置の態様等について説明する。 Hereinafter, the arrangement of the annular member 211 and the light bulb shaped lamp 101 in the second embodiment will be described.
　［環状部材］
　図１５は、実施の形態２における電球形ランプ１０１に環状部材２１１を配置する場合の分解斜視図である。 [Annular members]
FIG. 15 is an exploded perspective view when the annular member 211 is arranged in the light bulb shaped lamp 101 in the second embodiment.
　図１６は、実施の形態２における電球形ランプ１０１の環状部材２１１付近の断面の第１の例を示す断面図である。 FIG. 16 is a cross-sectional view showing a first example of a cross section near the annular member 211 of the light bulb shaped lamp 101 in the second embodiment.
　図１５および図１６に示すように、口金１８０と筐体１６０との間に、環状部材２１１を配置する。 15 and 16, an annular member 211 is disposed between the base 180 and the housing 160.
　つまり、口金１８０の円環状の端縁部１８６と筐体１６０との間に挟み込まれた状態で、環状部材２１１が電球形ランプ１０１に備えられる。 That is, the bulb-shaped lamp 101 is provided with the annular member 211 in a state of being sandwiched between the annular edge 186 of the base 180 and the housing 160.
　より具体的には、ネジ山が形成された螺合部１６２の付け根部分に存在する段差部１６３に、螺合部１６２が環状部材２１１を貫通した状態で、環状部材２１１が配置されている。 More specifically, the annular member 211 is arranged in a state in which the threaded portion 162 penetrates the annular member 211 at the stepped portion 163 existing at the base portion of the threaded portion 162 where the thread is formed.
　これにより、まず、環状部材２１１によって、端縁部１８６からの水分等の異物の浸入が抑制される。また、仮に、例えば環状部材２１１の経年劣化に起因して、水分等の異物が、端縁部１８６から侵入した場合であっても、介在部材２００によって、当該異物の筐体１６０の内部への侵入は抑制される。 Thereby, first, the annular member 211 suppresses the intrusion of foreign matters such as moisture from the end edge portion 186. Moreover, even if a foreign substance such as moisture enters from the end edge portion 186 due to, for example, aging deterioration of the annular member 211, the interposition member 200 causes the foreign substance to enter the inside of the casing 160. Intrusion is suppressed.
　なお、図１６において、環状部材２１１の下方に介在部材２００および環状部材２１１が存在しない空間が存在するが、当該空間が、例えば介在部材２００によって埋められていてもよい。 In FIG. 16, there is a space where the interposed member 200 and the annular member 211 do not exist below the annular member 211, but the space may be filled with the interposed member 200, for example.
　これにより、介在部材２００の、口金１８０および筐体１６０との間の接触面積が増加する。その結果、例えば、電球形ランプ１０１の放熱性が向上し、かつ、異物の筐体１６０の内部への侵入に対する抑制効果が向上する。 Thereby, the contact area between the base 180 and the casing 160 of the interposition member 200 increases. As a result, for example, the heat dissipation of the light bulb shaped lamp 101 is improved, and the effect of suppressing the entry of foreign matter into the housing 160 is improved.
　また、図１６では、環状部材２１１の内周面は、筐体１６０に接しているが、環状部材２１１の内周面は、筐体１６０から離れていてもよい。 In FIG. 16, the inner peripheral surface of the annular member 211 is in contact with the housing 160, but the inner peripheral surface of the annular member 211 may be separated from the housing 160.
　図１７は、実施の形態２における電球形ランプ１０１の環状部材２１１付近の断面の第２の例を示す断面図である。 FIG. 17 is a cross-sectional view showing a second example of a cross section near the annular member 211 of the light bulb shaped lamp 101 in the second embodiment.
　図１７に示すように、環状部材２１１の内周面と筐体１６０（螺合部１６２）との間に隙間がある場合、当該隙間に介在部材２００の一部が存在していてもよい。 As shown in FIG. 17, when there is a gap between the inner peripheral surface of the annular member 211 and the housing 160 (screwing portion 162), a part of the interposition member 200 may exist in the gap.
　また、図１８および図１９に示すように、口金１８０の端縁部１８６は、口金１８０が螺合部１６２と螺合した状態において、環状部材２１１の外周面の少なくとも一部を覆うように設けられてもよい。 Further, as shown in FIGS. 18 and 19, the end edge portion 186 of the base 180 is provided so as to cover at least a part of the outer peripheral surface of the annular member 211 in a state where the base 180 is screwed with the screwing portion 162. May be.
　図１８は、実施の形態２における電球形ランプ１０１の環状部材２１１付近の断面の第３の例を示す断面図である。 FIG. 18 is a cross-sectional view showing a third example of a cross section near the annular member 211 of the light bulb shaped lamp 101 in the second embodiment.
　図１９は、実施の形態２における電球形ランプ１０１の環状部材２１１付近の断面の第４の例を示す断面図である。 FIG. 19 is a cross-sectional view showing a fourth example of a cross section near the annular member 211 of the light bulb shaped lamp 101 in the second embodiment.
　例えば、図１８に示すように、口金１８０の端縁部１８６ａを、環状部材２１１を抱持するように内側に屈曲または湾曲した形状に形成する。これにより、口金１８０と環状部材２１１との接触面積を増加させることができる。 For example, as shown in FIG. 18, the end edge 186a of the base 180 is formed in a shape bent or curved inward so as to hold the annular member 211. Thereby, the contact area of the base 180 and the annular member 211 can be increased.
　その結果、口金１８０と環状部材２１１との間からの異物の浸入に対する抑制効果が向上する。 As a result, the effect of suppressing entry of foreign matter from between the base 180 and the annular member 211 is improved.
　また、図１９に示すように、口金１８０の端縁部１８６ｂは、端縁部１８６ｂによって形成される開口に近づくに従って口径が大きくなるよう形成されていることで、環状部材２１１の外周面の少なくとも一部を覆ってもよい。 Further, as shown in FIG. 19, the end edge portion 186 b of the base 180 is formed to have a larger diameter as it approaches the opening formed by the end edge portion 186 b, so that at least the outer peripheral surface of the annular member 211 is formed. A part may be covered.
　この構成によれば、図１９に示すように、口金１８０と螺合部１６２とが螺合されることで、弾性を有する環状部材２１１は、端縁部１８６ｂによって、筐体１６０の、Ｘ軸方向に平行な表面とＺ軸に平行な表面との双方に押圧される。 According to this configuration, as shown in FIG. 19, the base 180 and the screwing portion 162 are screwed together, so that the elastic annular member 211 is moved by the end edge portion 186b to the X axis of the housing 160. It is pressed against both the surface parallel to the direction and the surface parallel to the Z axis.
　つまり、環状部材２１１は、径方向および軸方向の成分を有する押圧力によって、筐体１６０の段差部１６３および螺合部１６２の外周面の双方に押し当てられる。 That is, the annular member 211 is pressed against both the stepped portion 163 of the housing 160 and the outer peripheral surface of the screwing portion 162 by a pressing force having radial and axial components.
　これにより、環状部材２１１と筐体１６０との密着性が向上し、その結果、筐体１６０と環状部材２１１との間からの異物の浸入に対する抑制効果が向上する。 Thereby, the adhesion between the annular member 211 and the casing 160 is improved, and as a result, the effect of suppressing the intrusion of foreign matter from between the casing 160 and the annular member 211 is improved.
　なお、図１５～図１９に示すような、介在部材２００と環状部材２１１とを備える電球形ランプ１０１を作製する場合、螺合部１６２の外周面における介在部材２００の形成と、筐体１６０への環状部材２１１の取り付けとはいずれが先に行われてもよい。 15 to 19, when the light bulb shaped lamp 101 including the interposed member 200 and the annular member 211 is manufactured, the formation of the interposed member 200 on the outer peripheral surface of the screwing portion 162 and the housing 160 are performed. Any of the attachment of the annular member 211 may be performed first.
　ここで、口金１８０の端縁部１８６からの異物の浸入を抑制するために、例えば、口金１８０と螺合部１６２とを螺合した後に、端縁部１８６と筐体１６０との隙間を埋めるように、端縁部１８６の端縁に沿って外側から硬化性のシリコーン樹脂等のシール剤で塗り固めることも考えられる。 Here, in order to suppress entry of foreign matter from the end edge portion 186 of the base 180, for example, after the base 180 and the screwing portion 162 are screwed together, the gap between the end edge portion 186 and the housing 160 is filled. As described above, it is also conceivable to apply a sealant such as a curable silicone resin from the outside along the edge of the edge 186.
　しかしながら、この場合、例えば、上記構成を有する電球形ランプを照明器具に取り付ける場合などに、口金１８０が螺合部１６２に対して回転した場合、その回転角度が僅かであっても、固化したシール剤の破壊が生じる場合がある。この場合、シール剤による異物の侵入防止機能は失われる。 However, in this case, for example, when the bulb lamp having the above-described configuration is attached to a lighting fixture, when the base 180 rotates with respect to the screwing portion 162, the solidified seal even if the rotation angle is slight. The destruction of the agent may occur. In this case, the function of preventing entry of foreign matter by the sealing agent is lost.
　一方、図１５等に示す環状部材２１１を備える電球形ランプ１０１では、仮に口金１８０が螺合部１６２に対して回転した場合、その回転角度が僅かであれば、環状部材２１１の弾性により、口金１８０の端縁部１８６と環状部材２１１との接触状態は維持される。 On the other hand, in the light bulb shaped lamp 101 including the annular member 211 shown in FIG. 15 and the like, if the base 180 is rotated with respect to the screwing portion 162, if the rotation angle is slight, the base is rotated by the elasticity of the annular member 211. The contact state between the end edge portion 186 of 180 and the annular member 211 is maintained.
　つまり、電球形ランプ１０１における、環状部材２１１による異物の侵入防止機能は、照明器具への取付作業または運搬時などに与えられる外力への耐性が高いといえる。 That is, it can be said that the function of preventing intrusion of foreign matter by the annular member 211 in the light bulb shaped lamp 101 is highly resistant to external force applied during mounting work or transportation to a lighting fixture.
　なお、本実施の形態では、介在部材２００の素材としてアクリルフォームを例示した。しかしながら、介在部材２００の素材は、他の素材であってもよい。例えば、樹脂および硬化剤等を含む粉体塗料を螺合部１６２に吹き付けることで、厚み方向の柔軟性を有する介在部材２００を形成してもよい。 In the present embodiment, acrylic foam is exemplified as the material for the interposition member 200. However, the material of the interposed member 200 may be another material. For example, the interposition member 200 having flexibility in the thickness direction may be formed by spraying a powder coating containing a resin, a curing agent, and the like onto the screwing portion 162.
　また、螺合部１６２ではなく、口金１８０の内周面に介在部材２００を形成した後に、口金１８０と螺合部１６２とを螺合させてもよい。 Alternatively, after the interposition member 200 is formed on the inner peripheral surface of the base 180 instead of the screwing part 162, the base 180 and the screwing part 162 may be screwed together.
　また、介在部材２００は、口金１８０と螺合部１６２とが螺合された後に、熱等によって膨張することで、口金１８０と螺合部１６２との間の隙間を埋めてもよい。 In addition, the interposition member 200 may be expanded by heat or the like after the base 180 and the screwing portion 162 are screwed together, thereby filling the gap between the base 180 and the screwing portion 162.
　（実施の形態３）
　次に、実施の形態３として、上述の電球形ランプ１００（１０１）を備える照明装置について、図２０を用いて説明する。 (Embodiment 3)
Next, as Embodiment 3, an illumination device including the above-described light bulb shaped lamp 100 (101) will be described with reference to FIG.
　図２０は、実施の形態３における照明装置２の概略断面図である。 FIG. 20 is a schematic cross-sectional view of the illumination device 2 according to the third embodiment.
　図２０に示すように、本発明の実施の形態に係る照明装置２は、例えば、室内の天井に装着されて使用される装置である。照明装置２は、実施の形態１における電球形ランプ１００または実施の形態２における電球形ランプ１０１と、点灯器具３とを備える。 As shown in FIG. 20, the lighting device 2 according to the embodiment of the present invention is a device that is used by being mounted on an indoor ceiling, for example. The lighting device 2 includes the light bulb shaped lamp 100 according to the first embodiment or the light bulb shaped lamp 101 according to the second embodiment, and the lighting fixture 3.
　点灯器具３は、点灯器具３に取り付けられた電球形ランプ１００（１０１）を消灯及び点灯させる器具である。点灯器具３は、天井に取り付けられる器具本体４と、電球形ランプ１００（１０１）を覆う透光性のランプカバー５とを備える。 The lighting device 3 is a device that turns off and turns on the light bulb shaped lamp 100 (101) attached to the lighting device 3. The lighting fixture 3 includes a fixture main body 4 attached to the ceiling and a translucent lamp cover 5 that covers the light bulb shaped lamp 100 (101).
　器具本体４は、ソケット４ａを有する。ソケット４ａには、電球形ランプ１００（１０１）の口金１８０がねじ込まれる。このソケット４ａを介して電球形ランプ１００（１０１）に電力が供給される。 The appliance body 4 has a socket 4a. The base 180 of the light bulb shaped lamp 100 (101) is screwed into the socket 4a. Electric power is supplied to the light bulb shaped lamp 100 (101) through the socket 4a.
　（実施の形態１～３についての補足）
　実施の形態１および２における電球形ランプ１００および１０１のそれぞれが備えるグローブ１４０の形状に特に限定はなく、全体として細長い形状であってもよく、一部に平面を有する立体形状であってもよい。 (Supplement for Embodiments 1 to 3)
There is no particular limitation on the shape of the globe 140 provided in each of the light bulb shaped lamps 100 and 101 in the first and second embodiments, and the shape may be an elongated shape as a whole, or may be a three-dimensional shape having a plane in part. .
　また、上記の実施の形態１および２において、発光モジュール１１０は、青色ＬＥＤチップである半導体発光素子１１２と黄色蛍光体とによって白色光を放出するが、白色光の放出の手法はこれに限らない。発光モジュール１１０は、例えば、赤色蛍光体及び緑色蛍光体を含有する蛍光体含有樹脂と青色ＬＥＤチップとの組み合わせによって白色光を放出してもよい。 In the first and second embodiments, the light emitting module 110 emits white light by the semiconductor light emitting device 112 that is a blue LED chip and the yellow phosphor, but the method of emitting white light is not limited thereto. . The light emitting module 110 may emit white light by a combination of a phosphor-containing resin containing a red phosphor and a green phosphor and a blue LED chip, for example.
　また、半導体発光素子（ＬＥＤチップ）１１２は、青色以外の色を発光するＬＥＤチップを用いても構わない。例えば、半導体発光素子１１２として紫外線発光のＬＥＤチップを用いる場合、封止体１１３内の蛍光体粒子としては、三原色（赤色、緑色、青色）に発光する各色蛍光体粒子を組み合わせたものを用いることができる。 The semiconductor light emitting element (LED chip) 112 may be an LED chip that emits a color other than blue. For example, when an ultraviolet light emitting LED chip is used as the semiconductor light emitting device 112, the phosphor particles in the sealing body 113 are a combination of phosphor particles that emit light of three primary colors (red, green, and blue). Can do.
　さらに、封止体１１３に、蛍光体粒子以外の波長変換材が含まれてもよい。例えば、波長変換材として、半導体、金属錯体、有機染料、または顔料など、ある波長の光を吸収し、吸収した光とは異なる波長の光を発する物質を有する材料を封止体１１３が含んでもよい。 Furthermore, the sealing body 113 may include a wavelength conversion material other than the phosphor particles. For example, the encapsulant 113 may include a material having a substance that absorbs light of a certain wavelength and emits light of a wavelength different from the absorbed light, such as a semiconductor, a metal complex, an organic dye, or a pigment, as a wavelength conversion material. Good.
　また、上記の実施の形態１および２において、半導体発光素子１１２としてＬＥＤを例示した。しかし、電球形ランプ１００および１０１が備える半導体発光素子１１２として、半導体レーザ、有機ＥＬ（Ｅｌｅｃｔｒｏ　Ｌｕｍｉｎｅｓｃｅｎｃｅ）または無機ＥＬ等の半導体発光素子が採用されてもよい。 In the first and second embodiments, the semiconductor light emitting element 112 is exemplified by an LED. However, a semiconductor light emitting element such as a semiconductor laser, an organic EL (Electro Luminescence), or an inorganic EL may be adopted as the semiconductor light emitting element 112 included in the light bulb shaped lamps 100 and 101.
　また、上記の実施の形態１および２において、発光モジュール１１０として、ＬＥＤチップ（ベアチップ）が実装基板に直接実装された構造であるＣＯＢ（Ｃｈｉｐ　Ｏｎ　Ｂｏａｒｄ）型のＬＥＤモジュールとしたが、これに限らない。 In the first and second embodiments, the light emitting module 110 is a COB (Chip On Board) type LED module having a structure in which an LED chip (bare chip) is directly mounted on a mounting substrate. However, the present invention is not limited to this. Absent.
　例えば、発光モジュール１１０は、表面実装型（ＳＭＤ：Ｓｕｒｆａｃｅ　Ｍｏｕｎｔ　Ｄｅｖｉｃｅ）のＬＥＤ素子が基板上に複数個実装することで構成されてもよい。なお、ＳＭＤ型のＬＥＤ素子とは、樹脂成形されたキャビティの中にＬＥＤチップを実装して当該キャビティ内を蛍光体含有樹脂によって封入したパッケージ型のＬＥＤ素子である。 For example, the light emitting module 110 may be configured by mounting a plurality of surface mount type (SMD) LED elements on a substrate. The SMD type LED element is a package type LED element in which an LED chip is mounted in a resin-molded cavity and the inside of the cavity is sealed with a phosphor-containing resin.
　また、実施の形態１における電球形ランプ１００と、実施の形態２における電球形ランプ１０１とは、筐体１６０等の基本的な構成が同一であるとした。しかしながら、筐体１６０等の基本的な構成が、実施の形態１における電球形ランプ１００と、実施の形態２における電球形ランプ１０１とで異なっていてもよい。 In addition, the light bulb shaped lamp 100 in the first embodiment and the light bulb shaped lamp 101 in the second embodiment are assumed to have the same basic configuration as the housing 160 and the like. However, the basic configuration of the housing 160 and the like may be different between the light bulb shaped lamp 100 in the first embodiment and the light bulb shaped lamp 101 in the second embodiment.
　また、以上説明した、電球形ランプ１００および１０１についての各種の変形例は、実施の形態３の照明装置２が備える、電球形ランプ１００または１０１に反映されてもよい。 Further, the various modifications of the light bulb shaped lamps 100 and 101 described above may be reflected in the light bulb shaped lamp 100 or 101 included in the lighting device 2 of the third embodiment.
　以上、本発明に係る電球形ランプおよび照明装置について、実施の形態およびその補足に基づいて説明したが、本発明は、実施の形態およびその補足に限定されるものではない。本発明の趣旨を逸脱しない限り、当業者が思いつく各種変形を本実施の形態およびその補足に施したもの、および、本実施の形態およびその補足における各種の構成要素を任意に組み合わせて構築される形態も、本発明の範囲内に含まれる。 As described above, the light bulb shaped lamp and the lighting device according to the present invention have been described based on the embodiment and the supplement thereof, but the present invention is not limited to the embodiment and the supplement.

Forms are also included within the scope of the present invention.
　例えば、実施の形態１における電球形ランプ１００がさらに、実施の形態２における介在部材２００を備えてもよい。 For example, the light bulb shaped lamp 100 in the first embodiment may further include the interposition member 200 in the second embodiment.
　また、実施の形態２における電球形ランプ１０１がさらに実施の形態１における円環溝１６４を備えてもよい。つまり、実施の形態２における環状部材２１１が、筐体１６０に設けられた円環溝１６４に埋設されてもよい。 Further, the light bulb shaped lamp 101 in the second embodiment may further include the annular groove 164 in the first embodiment. That is, the annular member 211 in the second embodiment may be embedded in the annular groove 164 provided in the housing 160.
