Abstract
【解決手段】上記LEDパッケージフレームは、LEDチップ、熱伝導率が優れた材料の塊からなって上記LEDチップが一面に装着され、側部に湾入された収納部が形成された熱伝達部材、一端側が上記熱伝達部材の収納部に収容され上記LEDチップと電気的に連結されたリード、及び上記熱伝達部材の収納部と上記リードを互いに隔離させるようにこれらの間に密着提供された電気絶縁層を含む。このようにリードを熱伝達部材に挿入することにより、LEDパッケージフレーム及び高出力LEDパッケージで高い熱伝導率及び安全性を維持しながらも嵩を減らすことが可能である。また、別途のジグなしにリードを熱伝達部材に固定することにより、LEDパッケージフレーム及び高出力LEDパッケージを大量生産することが可能である。
