Description
更に、各LEDが発した熱の一部が封止樹脂に伝えられるとともに、封止樹脂内で励起される蛍光体は発熱するが、この封止樹脂の熱の一部を、発光グループに対する熱拡散層の食み出した部位で受けて速やかにモジュール基板に伝導させることができるため、封止樹脂に熱が篭ることが抑制されてLEDの温度上昇を更に抑制できる。
しかも、熱拡散層の発光グループから食み出した部位が蛍光体入りの封止樹脂で覆われているため、前記部位上の封止樹脂に入射された光により励起された蛍光体の放射光の一部を、前記部位で光の利用方向に反射させて光の取出し効率を向上できる。
又、配線導体と熱拡散層が同種の金属製であるので、これら配線導体と熱拡散層を同時に製造できる。
Claims (1)
- モジュール基板と;
前記モジュール基板の表面に設けられて、前記モジュール基板の表面に凹凸を形成するとともに光を反射する複数の配線導体と;
前記複数の配線導体間であって、これら配線導体に隣接して前記モジュール基板の表面の一部に設けられて、前記配線導体とともに前記モジュール基板の表面に凹凸を形成し、かつ、隣接した前記配線導体との間に前記凹凸の凹部を形成するとともに前記配線導体と同種の金属からなり光を反射する熱拡散層と;
前記配線導体を通じて給電されるとともに前記熱拡散層の全長より短い発光グループを形成し、この発光グループから前記熱拡散層が食み出すように前記熱拡散層上に実装された複数個のLEDと;
前記熱拡散層、配線導体、及びLEDを埋めるとともに前記凹部を満たしかつ一部が前記熱拡散層の前記発光グループから食み出した部位に接着して前記モュール基板に被着された蛍光体入りの透光性封止樹脂と;
を具備したことを特徴とする発光モジュール。
