Description
内面における光反射面によってカップ部から出て行く方向への方向変換とを行うものであり,換言すると,螢光物質が分散された光透過性合成樹脂の内部を,光反射面の前後における長い経路にわたって透過することにより,この光透過性合成樹脂を透過するときにおける光の減衰率が可成り大きいから,光の輝度がそれだけ低いという問題がある。
「少なくとも,二本の一対のリード端子と,一方のリード端子の先端に内周面を外向きに広がる形状の光反射面とするように凹み形成したカップ部と,発光ダイオードチップと,前記両リード端子における先端の部分をパッケージする透明合成樹脂体,或いは,前記カップ部内に前記発光ダイオードチップをパッケージするように充填した透明合成樹脂体とから成る発光ダイオードランプにおいて,
前記発光ダイオードチップを,透明なn型半導体基板の上面にn電極を形成する一方,前記n型半導体基板の下面に青色発光層,p型半導体層及びp電極を形成して成る積層構造にし,この発光ダイオードチップの周囲における各側面のうち前記n型半導体基板の部分に,前記青色発光層に隣接する部分から前記n電極に向かって内向きにした傾斜面を設け,更に,前記発光ダイオードチップを,その周囲における各側面を螢光物質の粉末を含む光透過性合成樹脂にて被覆して直方体に構成して,前記カップ部の内部に,当該発光ダイオードチップにおけるp電極を下向きにn電極を上向きにして配設し,その下向きのp電極を前記カップ部の内底面に電気的に接続するようにダイボンディングする。」
ことを特徴としている。
「少なくとも,絶縁体と,この絶縁体に内周面を外向きに広がる形状にして凹み形成したカップ部と,前記カップ部の内面に光反射性を有するように形成した電極膜と,発光ダイオードチップと,前記カップ部内に前記発光ダイオードチップをパッケージするように充填した透明合成樹脂体とから成る発光ダイオードランプにおいて,
前記発光ダイオードチップを,透明なn型半導体基板の上面にn電極を形成する一方,前記n型半導体基板の下面に青色発光層,p型半導体層及びp電極を形成して成る積層構造にし,この発光ダイオードチップの周囲における各側面のうち前記n型半導体基板の部分に,前記青色発光層に隣接する部分から前記n電極に向かって内向きにした傾斜面を設け,更に,前記発光ダイオードチップを,その周囲における各側面を螢光物質の粉末を含む光透過性合成樹脂にて被覆して直方体に構成して,前記カップ部の内部に,当該発光ダイオードチップにおけるp電極を下向きにn電極を上向きにして配設し,その下向きのp電極を前記カップ部の内底面における電極膜に接続するようにダイボンディングする。」ことを特徴としている。
「前記請求項1又は2の記載において,前記発光ダイオードチップにおける上向きのn電極に,螢光物質の粉末を含む光透過性合成樹脂を塗布する。」
