Description
<構成>
図1は、本発明の実施形態に係る照明用光源の構成を示す図である。本実施形態では、E型口金をもつ電球代替の照明用光源を例にして説明する。
実装基板21は、金属基板23およびセラミックス層24から構成されている。発光部22は、発光素子であるLED25および波長変換部材であるシリコーン樹脂成形体26から構成されている。LED25は青色光(ピーク波長が460nm±10nm程度)を出射する、いわゆる青色LEDである。シリコーン樹脂成形体26は、青色光を吸収して黄色光を放出する黄色蛍光体を含有している。LED25はセラミックス層24の上面に配置されて接合材31により固着されている。なおLED25とセラミックス層24とは直接接触させることとしてもよいし、熱伝導性ペースト等を介在させて接触させることとしてもよい。セラミックス層24の上面には、LED25以外に配線パターン32が配設されており、LED25上面のパッド33と配線パターン32とがワイヤ34により電気的に接続されている。
金属基板23は、例えばアルミニウムや銅などの金属材料、あるいは金属材料を主たる成分とする複合材料からなり、基板の厚みは0.1mm以上5.0mm以下である。
<検証>
図4乃至図11は、反射材材質別の分光反射率を示すグラフである。また図12は、反射材材質別の初期時および熱劣化後の分光反射率を示すテーブルである。
(1)実施形態では実装基板上面に配線パターンを形成しているが、配線パターンを極力削減することにより光取出し効率を向上させることとしてもよい。例えば図13に示すLEDモジュールでは、隣接するLED25どうしを直接ワイヤ34で接続している。これによりセラミックス層24を被覆する配線パターンの面積を削減することができ、光取出し効率を向上させることができる。
(2)実施形態では発光素子としてLEDを挙げているが、発光トランジスタ、有機EL、無機EL等でも適用可能である。
(3)実施形態では波長変換材料として蛍光体を挙げているが、半導体、金属錯体、有機染料、顔料など、ある波長の光を吸収し吸収した光とは異なる波長の光を発する物質を含んでいる材料であれば適用可能である。
(4)実施形態では波長変換部材として蛍光体粒子を含有するシリコーン樹脂成形体を挙げているが、蛍光体粒子を焼結して得られるセラミックス成形体でも適用可能である。
(5)実施形態では青色LEDと黄色蛍光体との組み合わせにより白色光を得ることとしているが、紫外線LEDと三原色を発光する各蛍光体との組み合わせとしてもよい。
(6)実施形態では電球代替の照明用光源を挙げているが、本発明はこれに限らず、一般的な照明用光源にも適用可能である。ただし電球代替の照明用光源はヒートシンクの寸法が制限されるため、一般的な照明用光源に比べて放熱特性をより向上させる必要がある。したがって電球代替用の照明用光源に本発明を適用すると、より効果的である。
(7)実施形態では特に言及していないがセラミックス層が多孔質となる場合にはセラミックス層に封孔処理を施すこととしてもよい。
(8)金属基板の片面だけでなく両面にセラミックス層を被覆させることとしてもよい。また、金属基板の両面および側面を含む全面にセラミックス層を被覆させることとしてもよい。
(9)通常、金属とセラミックスでは熱膨張係数が異なるので、実装基板の温度がLEDの点灯により上昇すると、実装基板に反りが生じることがある。これは、金属基板の温度が上昇したとき、金属基板の表面側はセラミックス層に固定されているので膨張しにくく、金属基板の裏面側は自由なので膨張しやすいからである。実装基板の反りはヒートシンクとの熱接触の劣化につながるので、温度が上昇しても反りが生じにくい構造を採用することが好ましい。
