Description

【0001】
【発明の属する技術分野】
本発明は電球形蛍光ランプに関するものである。
【0002】
【従来の技術】
従来の電球形蛍光ランプは、図1を参照して説明すると、電球用口金ソケットに装着し電球用口金ソケットから口金2を通じて発光管3と口金2の間のケース1内に具備されている点灯回路5に電力を供給し、ランプを点灯している。
【0003】
これら従来の電球形蛍光ランプにおいて、点灯回路以外の機能を有した電気回路をさらに具備せしめると、発光管3と口金2の間のケース1部分に回路を内蔵させようとした場合、ケース部分1が大きくなってしまう問題があった。
【0004】
【発明が解決しようとする課題】
本発明が解決しようとする課題は、従来において点灯回路を収納していた発光管3と口金2の間のケース1を小型化し、器具への適合率を上げるとともに、ケースを小型化した分、発光管長をより長くして光束を多く得られるようにし、よりコンパクトな電球形蛍光ランプおよび、点灯のための回路以外の付加機能を有する電気回路を具備しながらも、従来の発光管と口金の間のケース部分の大きさを小さく保つことができる電球形蛍光ランプを提供することにある。
【0005】
【課題を解決するための手段】
上記課題を解決するため、本発明においては発光管と上記発光管の点灯回路と少なくとも上記点灯回路を被せるケースと口金を具備した電球形蛍光ランプにおいて、上記ケースに同じPBT樹脂などの電気絶縁性の耐熱性合成樹脂材料で造られた円筒形あるいは柱状のケースを具備することで、発光管と口金の間のケース内に具備されていた点灯回路および点灯回路以外の機能を有した電気回路の全体あるいは一部を上記円筒形あるいは柱状のケースに内蔵することで、発光管と口金の間のケースの寸法を小さくするようにした。
【0006】
【発明の実施の形態】
本発明に係る電球形蛍光ランプの実施例を添付図面を参照しながら以下詳細に説明する。
(実施例1)
図2は本発明の一実施の形態による電球形蛍光ランプを示す。図2において1はPBT樹脂などの電気絶縁性および耐熱性合成樹脂材料で形成されカバー部で、その一端には電球口金2が取り付けられている。発光管3は湾曲した二つあるいはそれ以上の透光性気密容器からなり、上記容器には水銀および希ガスを含む放電媒体が封入され、容器内壁には蛍光体が塗布されている。
【0007】
本実施例においては、湾曲した二つあるいはそれ以上の発光管にはさまれたランプ中央部の空間に、発光管に触れることのない円筒形あるいは柱状のケース4を設け、その内部に従来カバー部1に接続するケース内に収納されていた電気回路の少なくとも一部を収納させた。
【0008】
本実施例によれば、図1のカバー部1を従来よりも小さくすることが可能である。また、カバー部分が小さくなった分、発光管の長さを長くすることができ、発光部分を大きくすることが可能である。
(実施例2)
図3は本発明の他の実施例を示す電球形蛍光ランプである。本実施例において、点灯回路5はカバー1に接続する発光管と口金の間のケース内に収納されている。そして点灯回路以外の効果を発揮する様々な電気回路6またはその一部が、実施例1において記述したような円筒形あるいは柱状のケース4に収納されている。
【0009】
例えば、上記付加的な電気回路6としてマイナスイオン発生回路を上記ケース4内に収納せしめれば、室内照明と同時にランプ周囲の空気内にマイナスイオンを放出させることで、環境改善効果を得ることができる。
【0010】
ここで、上記ケース4内の電気回路には、電球口金2からカバー1内のリード線7により供給され、発光管と口金の間のケースを大きくすることのない構造となっている。また、上記ケース4は、電気回路6の放熱と例えばマイナスイオン発生回路によるマイナスイオン放散作用を十分発揮できるように、必要に応じて開口部8を持たせた構造としてもよい。
【0011】
さらに、上記ケース4の外面には、光反射性の塗布またはメッキ被膜を施すことで、発光管の光を周囲に反射させて明るさを保持ないしは高めることができる。
【0012】
【発明の効果】
以上に述べたように本発明によれば、湾曲した二つあるいはそれ以上の発光管にはさまれた部分に平行に円筒形あるいは柱状にケースが伸びた形状の内部に点灯回路もしくは点灯のための回路以外の機能を有する電気回路の全部あるいは一部を収納することで、発光管と口金の間のケース部分を大きくすることなくコンパクトで付加機能も具備する電球形蛍光ランプを提供することができる。
