Claims (1)
- LEDチップと、LEDチップが実装された実装基板と、当該実装基板におけるLEDチップの実装面側でLEDチップを囲む円筒状の枠体と、枠体の内側に透明樹脂材料を充填して形成されてLEDチップおよび当該LEDチップの各電極に電気的に接続されたボンディングワイヤを封止し且つ弾性を有する封止部と、封止部に重ねて配置されたレンズと、LEDチップから放射された光によって励起されてLEDチップの発光色とは異なる色の光を放射する蛍光体および透明材料により形成されてなり実装基板の前記実装面側でレンズの光出射面および枠体の外側面との間に空気層が形成される形で配設されるドーム状の色変換部材とを備え、実装基板は、熱伝導性材料からなりLEDチップが搭載される伝熱板と、伝熱板側とは反対の表面にLEDチップの両電極それぞれと電気的に接続されるリードパターンが設けられるとともに伝熱板におけるLEDチップの搭載面を露出させる窓孔が設けられ伝熱板に固着された配線基板とからなり、LEDチップは、両電極が一表面側に形成されており、当該LEDチップと伝熱板との線膨張率差に起因して当該LEDチップに働く応力を緩和するサブマウント部材を介して伝熱板に前記一表面が対向する形で実装され、各電極それぞれがサブマウント部材に設けた導体パターンおよびボンディングワイヤを介して互いに異なるリードパターンと電気的に接続され、枠体は、封止部の透明樹脂材料の線膨張率と同等の線膨張率を有する透光性材料である透明樹脂により形成されたものであり、実装基板に固着されてなることを特徴とする発光装置。
