Abstract
【解決手段】半導体発光素子たるLEDチップ1を備え白色系の光を発光させる発光装置4と、該発光装置4を実装してなる実装基板5とを有する発光ユニット10であり、白色系の光を発光する発光装置4の発光部4aaを少なくとも覆って別途に形成され、発光装置4からの上記白色系の光よりも相関色温度がより低い光を発光する波長変換部6が設けられてなる。
【選択図】図1
Description
図6(b)に示す発光装置は、パッケージ3の凹部内に発光ダイオード36を配置し、発光ダイオード36を電気端子31で給電可能に構成している。また、発光装置は、発光ダイオード36から発光され、封止部34を介して波長変換部6’を透過する光αと、発光ダイオード36から発光され、封止部34を介して前記凹部の表面に設けられた反射材35で反射させてから波長変換部6’を透過する光βとにより光の利用効率を高めている。
本実施形態の発光ユニット及びこれを用いた照明器具について図1および図2を用いて説明する。なお、図1および図2において、同一の構成要素には、同一の符号を付している。
本実施形態の図2に示す照明装置20の基本構成は、図1に示す実施形態1の発光ユニット10を用いた照明装置20と略同一の構成であり、図3に示すように、実施形態1におけるキャップ形状の波長変換部6に変えて、シート状の波長変換部6e,6f,6gを用いた点が異なる。なお、実施形態1と同様の構成要素には、同一の符号を付して説明を適宜省略する。
本実施形態の図4に示す照明装置20の基本構成は、図3に示す実施形態2の発光ユニット10を用いた照明装置20と略同一であり、図4に示すように、実施形態2における波長変換部6を透光性パネルに形成する代わりに、波長変換部6をグローブカバー21の内側面に形成させた点が異なる。なお、実施形態2と同様の構成要素には、同一の符号を付して説明を適宜省略する。
