Description
(発光装置の構造)
図1(a)、(b)は、それぞれ実施の形態に係る発光装置の上面図及び側面図である。また、図1(c)は、図1(a)の線分A−Aにおいて切断された実施の形態に係る発光装置の垂直断面図である。
ケース2は、射出成形により製造される。まず、樹脂21とガラス繊維22の原料を樹脂押出機に投入し、シリンダーのヒーターの熱と、スクリューの回転の摩擦熱で樹脂を溶融する。その後、ガラス繊維22の原料を含む溶融した樹脂21の原料にスクリューにより圧力をかけ、樹脂押出機のノズルから金型に射出、注入する。
本実施の形態によれば、ケースに含まれるガラス繊維の平均長と、ケースの側壁部の肉厚との関係を適切に設定することにより、LEDチップから発せられる光のケースによる吸収を効果的に抑制し、光損失を抑制することができる。そのため、発光装置の光取出効率を向上させることができる。

4 LEDチップ
6 封止材
21 樹脂
22 ガラス繊維
Claims (1)
- 樹脂と、当該樹脂と屈折率の異なるガラス繊維の原料を樹脂押出機に投入する工程と、
前記樹脂押出機において前記ガラス繊維を含む前記樹脂を加熱溶融し、スクリューを70rpm以上、75rpm以下の回転数にすることにより前記スクリューによって前記ガラス繊維を含む溶融樹脂にかかる圧力を制御し、それによって前記ガラス繊維の平均長が低下するのを抑えながら、前記樹脂押出機のノズルから前記ガラス繊維を含む前記溶融樹脂を押し出す工程と、
前記ガラス繊維を含む前記溶融樹脂を前記金型で成形して、肉厚が65μm〜105μmの側壁、及び底壁部を有し、前記底壁部上にリードフレームを有するケースを形成する工程と、
前記リードフレーム上にLEDチップを実装する工程を備え、
前記ガラス繊維を含む前記溶融樹脂を押し出す工程は、押し出し成形後の前記ガラス繊維の平均長が230μm以上、前記ケースの短手方向の幅以下になるように行う、
