2.ケース
(1)有底筒形状
ケース11は、断面が円形状をした有底筒状であったが、他の形状でも良い。他の形状としては、断面形状が三角形等の多角形状(正多角形を含む。)、楕円形状、長円形状等した有底筒形状である。
(2)材料
ケースは、樹脂材料により構成されていたが、他の材料を用いることもできる。他の材料として例えば金属材料を利用した場合、発光部3の発光時の熱がケース側に伝わりやすくなり、さらに、ケースに伝わった熱は外囲器へと伝わり放熱される。但し、金属材料の場合、発光部3、口金15及び回路ユニット13との絶縁性を確保するための対策(例えば絶縁膜の塗布等である。)が必要である。
(3)長さ
実施形態でのケース11の全長は、発光部3と筺体17のグローブ19側の端面とが略一致するように構成されていたが、変形例1(図10の(c))で説明したように、発光部3を搭載した部分が筺体207からグローブ209側に突出するように構成しても良い(カバー257の有無は問わない。)。
(4)構造
ケースは有底筒状をし、その底部に発光部が設けられていたが、底部を有しない筒状のケースとすることもできる。
3.ケースと筺体との組み立て
(1)組み立て位置
第1の実施形態に係るランプ部品5(ケース11)は、外囲器7(筺体17)に対して互いに定まった位置で取着される構造を有していない。つまり、ケース11の係合凹み33は、筺体17に形成されている周方向に4個ある係合突起89のどれか1つに係合するようになっている。
(2)係合手段
第1の実施形態における取着手段は、ケースの厚み方向に凹入・突出する凹み・突起とで構成されていたが、凹入・突出する方向は、互いに係合して、ランプ部品を筺体に取着することができれば、ケースの厚み方向以外であっても良く、特に限定されるものではない。例えば、上述したようなガイド手段に係合手段を設けても良い。
(3)取着方法
実施形態等では、ランプ部品と外囲器との取着に係合手段を利用したが、他の手段を利用することもできる。なお、他の手段と係合手段とを組み合わせても良い。
4.発光部
実施形態では、発光部として青色発光のLEDと黄色に発光(波長変換)する蛍光体粒子とを組み合わせて白色を発するようにしているが、他の組み合わせであっても良い。
5.外囲器
(1)筐体
実施形態では、外囲器は、グローブと筺体とから構成されていたが、外囲器は、グローブだけであっても良い。この場合、グローブは、本体格納空間を内部に有する必要があり、その開口からランプ部品の口金部分以外を受け入れて、取着する構造が必要となる。
(2)中空
実施形態では、筐体17,123,461等は、ランプ部品5,103,451等用の貫通孔87,127,463等を除いた部分が中実であった。しかしながら、筐体は、貫通孔を含めた中空部を内部に有する構造であっても良いし、貫通孔を含めない中空部を内部に有する構造であっても良い。
