Description
[発光装置の構成]
まず、実施の形態1に係る発光装置の構成について図面を用いて説明する。図1は、実施の形態1に係る発光装置の外観斜視図である。図2は、実施の形態1に係る発光装置の平面図である。図3は、実施の形態1に係る発光装置の内部構造を示す平面図である。図4は、図2のA−A線における断面図である。図5は、図2のB−B線における断面図である。なお、上記の図3は、図2において封止部材13及びダム材15を取り除き、LEDチップ12の配列及び配線パターンなどの内部の構造を示した平面図である。
次に、発光装置10の製造方法について説明する。図6は、発光装置10の製造方法のフローチャートである。図7は、発光装置10の製造方法を示す断面図である。なお、図7は、図2のB−B線における断面に対応する断面図である。
発光装置10では、バッファ層14が設けられ、バッファ層14の上にダム材15が設けられることが特徴である。
実施の形態1のように、バッファ層14がガラスコート層である場合、バッファ層14が透明であるために、バッファ層14からの漏れ光が問題となる可能性がある。
次に、実施の形態2に係る照明装置200について、図8及び図9を用いて説明する。図8は、実施の形態2に係る照明装置200の断面図である。図9は、実施の形態2に係る照明装置200及びその周辺部材の外観斜視図である。
以上、実施の形態に係る発光装置10、及び照明装置200について説明したが、本発明は、上記実施の形態に限定されるものではない。
