Description
(蛍光体層転写シートの作製)
ポリエチレンテレフタレートからなる厚み50μmの離型基材を用意した(図2(a)参照)。
ベース基板、導体パターンおよびハウジングを備える基板と、複数の青色発光ダイオードとを用意した(図3(a)参照)。なお、各青色発光ダイオードを、ワイヤを介して導体パターンとワイヤボンディングした後、封止層によって封止した。
粒子含有樹脂組成物の調製において、シリカ粒子(光散乱粒子)を配合しなかったこと、および、色調を合わせるために蛍光体層の厚みを500μmにしたこと以外は、実施例1と同様にして、蛍光体層を形成することにより、蛍光体層転写シートを作製し、続いて、発光装置を製造した。
(色度の測定)
実施例1および比較例1の蛍光体層転写シートの色度を、図4に示す異なる波長毎に、分光放射計(瞬間マルチ測光システム:MCPD−7000、大塚電子社製)を用いて測定して、xy色度図を作成した。それを、図4に示す。
10 基板
11 発光ダイオード
18 発光装置
