Abstract
【解決手段】本発明の一態様に係る発光装置10は、発光素子2と、発光素子2を封止する封止材6と、を有し、封止材6は、発光素子2に接するラジカル重合型樹脂からなる第1の層6aと、第1の層6aの上面を覆う非ラジカル重合型樹脂からなる第2の層6bとを有する。
【選択図】図1
Description
図1は、実施の形態に係る発光装置の垂直断面図である。発光装置10は、リードフレーム1に実装された発光素子2と、発光素子2を封止する封止材6と、を有する。リードフレーム1、発光素子2、及び封止材6は、ケース5内に形成される。
本実施の形態によれば、封止材6の大部分を占める第1の層6aをラジカル重合型樹脂で形成することにより、樹脂材料の廃棄量を減らし、また、発光装置10の信頼性を向上させることができる。そして、第1の層6aの上面を覆う非ラジカル重合型樹脂からなる第2の層6bを形成することにより、第1の層6aの硬化不良を抑えることができる。
