Abstract
【解決手段】基板上に発光素子が搭載され、発光素子は樹脂で覆われている。基板上には、基板の主平面方向についての熱伝導率が、厚さ方向についての熱伝導率よりも大きい異方性熱伝導材が搭載されている。異方性熱伝導材の側面は樹脂と接触している。これにより、異方性熱伝導材は、樹脂からの熱を受け取って主平面方向に伝導し、発光素子および/または樹脂から離れた位置で基板に放熱することができる。異方性熱伝導材としては、例えばシート状のグラファイトを1層以上積層したもの用いる。
【選択図】図1
Description
本発明の第1の実施形態の半導体発光装置について図1(a),(b)を用いて説明する。図1(a)のように、半導体発光装置は、金属基板1の上に、絶縁性基板2を固定し、その上に半導体発光素子3を実装している。絶縁性基板2の表面には、配線が配置されている。半導体発光素子3の実装方法としては、公知の手法、例えば金バンプ等を用いる。半導体発光素子3の上面および側面は、蛍光体含有樹脂層4により被覆されている。蛍光体含有樹脂層4の外形は、直方体である。
第2の実施形態の発光装置について図5を用いて説明する。
第3の実施形態の発光装置について図8を用いて説明する。
第4の実施形態の発光装置について図9を用いて説明する。
第5の実施形態の発光装置について図10および図11を用いて説明する。
第6の実施形態の発光装置について図12を用いて説明する。
第1〜第6の実施形態では、上面形状が長方形の異方性熱伝導材5を用いたが、熱源である蛍光体含有樹脂層4の位置と、放熱させたい位置に応じて、異方性熱伝導材5の形状を図13(a)〜(d)のように任意の形状に設計可能である。
実施例として図1(a),(b)の発光装置を製造した。
