(封止層の用意)
配線が形成された基板の上面において、ハウジングを設置し、次いで、青色発光ダイオードをハウジング内に実装し、その後、シリコーン樹脂からなる封止材をハウジング内に、青色発光ダイオードを被覆するように充填して、その後、封止材を硬化させて、青色発光ダイオードを封止した。これにより、封止層を用意した(図1(a)参照)。
40℃に加温したシラノール両末端ポリジメチルシロキサン(シラノール両末端ポリシロキサン、式(1)中、R1およびR2がすべてメチル、nの平均が155、数平均分子量11,500)2031g(0.177モル)に対して、ビニルトリメトキシシラン(アルケニル基含有アルコキシシラン)15.76g(0.106モル)、および、(3−グリシドキシプロピル)トリメトキシシラン(エポキシ基含有アルコキシシラン)2.80g(0.0118モル)とを配合して、攪拌混合した。
蛍光体層を、封止層の上面およびハウジングの上面の両方に貼り合わせた(図1(b)参照)。
蛍光体層を用意する工程において、シリコーン樹脂組成物に代えて、ホウ素化合物含有シリコーン樹脂組成物を調製し、これから蛍光体含有樹脂組成物を調製し、さらに、蛍光体含有樹脂組成物をBステージ状態とするための加熱条件を、150℃、30分間に変更した以外は、実施例1と同様に処理して、青色発光ダイオード装置を作製した。
