[1.概略構成]
図1は、本発明の実施形態に係る照明用光源1の概略構成を示す外観斜視図である。図2は、照明用光源1の分解斜視図である。図3は、図1におけるA-A’矢視図である。図4は、図3の断面図を異なる角度から見た斜視断面図である。図4においては、回路ユニット50については、断面としていない。また、図3においては、電子部品52については、断面としていない。
〈2-1.筐体〉
筐体10は、熱伝導性を有する絶縁性の材料からなる筒状の部材であり、大径部11と小径部12とから成る。大径部11および小径部12は、例えば、両側が開口した略円筒形状であって、円筒の軸とランプ軸Jとが一致するように軸方向に互いに連接され、一体的に形成されている。前方側に位置する大径部11は、前方から後方へ向けて縮径した略円筒形状を有し、大径部11には回路ユニット50、絶縁部材70、ヒートシンク60および発光部40が、下方側から上方側にこの順番に収容されている。回路ユニット50の電子部品52の一部は、小径部12内にも収容されている。一方、後方側に位置する小径部12には口金30が外嵌されており、これによって筐体10の下端側開口10bが塞がれている。筐体10の上端側開口10aは、ヒートシンク60により塞がれている。なお、図3および図4においては、一部の電子部品にのみ符号を付している。
グローブ20は、発光部40を覆う部材であり、グローブ20の開口側端部21が筐体10の上端側開口10aに嵌め込まれる。そして、グローブ20の係止爪22が大径部11に設けられた係合孔11bと係合し、グローブ20の係合孔23がガイド部材80の上端部に設けられた係止爪81と係合することにより、グローブ20が筐体10に対して固定される。
口金30は、照明用光源1が照明器具に取り付けられ点灯された際に、照明器具のソケットから電力を受けるための部材である。口金30の種類は、特に限定されるものではないが、本実施の形態ではエジソンタイプであるE26口金が使用されている。口金30は、略円筒形状であって外周面が雄ネジとなっているシェル部31と、シェル部31に絶縁部32を介して装着されたアイレット部33とを備える。シェル部31は配線53を介して、アイレット部33は配線54を介して、それぞれ回路ユニット50と接続されている。
発光部40は、光源として用いられる半導体発光素子としてのLED41、LED41が実装された実装基板42、および、実装基板42上においてLED41を被覆する封止体43を備える。実装基板42の封止体43に覆われていない部分には、回路ユニット50からLED41を発光させるための電力を受ける受電端子としてランド44が形成されている。発光部40は、回路ユニット50を介して口金30とは反対側に配されており、LED41の主出射方向は照明用光源1の前方(紙面上方)に向けて配置されている。
回路ユニット50は、LED41を点灯させるためのものであり、回路基板51と、当該回路基板51上に配された各種の電子部品52とを有している。
ヒートシンク60は、LED41から発せられる熱を、実装基板42を介して受け取り、その熱を筐体10を介して口金30へと伝導させ、口金30から照明装置等の外部へと放熱させるための部材であり、高熱伝導性の材料により構成されている。高熱伝導性の材料としては、金属や熱伝導性樹脂等が用いられ、本実施形態においては、例えば、アルミが用いられている。
絶縁部材70は、樹脂やセラミック等の絶縁性の部材から成り、回路ユニット50とヒートシンク60との間に配され、双方間の電気的絶縁性を確保するための部材である。絶縁部材70の下面には凸部73が形成されており、組み付けられた際に回路基板51に当接して一定の距離を確保する。
ガイド部材80は、筐体10の大径部11の内周面11a上に設けられた大径部11の上端側から下端側へと向かう方向に伸びる長尺の部材であり、筐体10と同様の材料を用いて大径部11と一体的に形成されている。ガイド部材80は、その上端部に係止爪81が形成されており、筐体10の上端側から下端側へと向かうにつれて、長手方向に直交する方向(筐体10の周方向に略沿った方向)の幅が徐々に大きくなっている。(以下、ガイド部材80の長手方向を、単に「長手方向」といい、長手方向に直交する方向および筐体10の周方向に略沿った方向の大きさを、単に「幅」という。また、筐体10の上端側を、単に「上端側」といい、筐体10の下端側を、単に「下端側」という。なお、大径部11の上端側および下端側は、筐体10の上端側および下端側とそれぞれ同じである。)回路ユニット50,絶縁部材70,およびヒートシンク60(以下、回路ユニット50,絶縁部材70,ヒートシンク60を「部品ユニット」と呼ぶ場合がある。)にはそれぞれ欠損部57,75,63が形成されており、これら部品ユニットは、上端側開口10aから筐体10内部に挿入された場合に、欠損部57,75,63内にガイド部材が位置した状態でガイド部材80に沿って移動可能となっている。また、欠損部57,75,63内にガイド部材が位置した状態で各部品ユニットが筐体10内に挿入されるため、各部品ユニットのランプ軸Jを中心とした回転方向の位置決めが、筐体10への挿入と同時になされる。
図5は、筐体10内に収容されているときの回路ユニット50、絶縁部材70、ヒートシンク60、およびガイド部材80の状態を模式的に示す斜視断面図である。図5においては、わかりやすくするために、部品ユニットについては、それぞれの欠損部とその周辺の部位のみを板状の部材として単純化して図示しており、回路ユニット50は、各種電子部品52については図示を省略し、回路基板51についてのみ示している。また、グローブ20、発光部40、および各配線についても図示を省略している。
以上、各部品ユニットの長手方向に沿った下端側への移動がガイド部材80により係止される構造について説明した。次に、照明用光源1が組み付けられた状態において、各部品ユニットの筐体10内部における長手方向に沿った上端側への移動に対する係止構造について以下に説明する。
以上説明したように、本実施形態の構成によると、各部品ユニットの欠損部内にガイド部材80が位置するように筐体10内に部品ユニットが挿入されるため、部品ユニットのランプ軸Jを中心とした回転方向の位置決めを作業員の熟練度に係らず容易に行うことができる。
以上、本発明の構成を実施形態に基づいて説明したが、本発明は上記実施形態に限られず、以下のような変形例を実施することができる。なお、説明の重複を避けるため、実施形態と同じ構成要素については、同符号を付して、その説明を省略する。
