Abstract
【解決手段】発光モジュール10は、金属基板12と、金属基板12の上面を被覆する絶縁層24と、絶縁層24の上面に形成された導電パターン14と、金属基板12の上面に固着されて導電パターン14と電気的に接続された発光素子20とを主要に備える。更に、金属基板12に溝を設けて曲折加工することにより曲折部13が設けられている。
【選択図】図1
Description
本形態では、図1から図3を参照して、発光モジュール10の構成を説明する。
次に、図4から図13を参照して、上記した構成の発光モジュール10の製造方法を説明する。
図4を参照して、先ず、発光モジュール10の基材となる基板40を用意して、導電パターンを形成する。
図5を参照して、次に、基板40の各ユニット46に関して、絶縁層を部分的に除去して開口部48を設ける。
図6を参照して、次に、開口部48から露出する基板40の上面から凹部18を形成する。凹部18の形成は、選択的なエッチング、ドリル加工、プレス加工等により可能であるが、本工程ではプレス加工を採用した。
本工程では、各ユニット46同士の間に分離用の分離溝(第1溝54および第2溝56)を設けると共に、各ユニット46に、曲折のための溝58を設ける。本工程では、高速で回転するカットソーにより、これらの溝を一括して形成することができる。
本工程では、開口部48から露出する基板40の表面を被覆層34により被覆する。
次に、各ユニット46の凹部18に発光素子20(LEDチップ)を実装して、電気的に接続する。
次に、基板40に設けた各ユニット46の凹部に封止樹脂32を充填させて、発光素子20を封止する。封止樹脂32は、蛍光体が混入されたシリコン樹脂からなり、液状または半固形状の状態で、封止樹脂32を凹部18および開口部48に充填されて固化される。このことにより、発光素子20の側面および上面と、発光素子20と金属細線16との接続部が、封止樹脂32により被覆される。
次に、第1溝54および第2溝56が形成された箇所で、基板40を各ユニット46に分離する。
本工程では、前工程にて分離された各ユニットの金属基板12に対して、折り曲げ加工を行う。図13(A)は折り曲げ加工を施す前の金属基板12の断面図であり、図13(B)は折り曲げ加工を行った後の金属基板12の断面図である。
本形態では、図14を参照して、金属基板を曲折させて、この曲折が導電パターンに示す影響を確認した実験結果を説明する。図14(A)は曲折された金属基板を側方から撮影した写真であり、図14(B)、図14(C)、図14(D)および図14(E)は金属基板が加熱される温度を変化させて金属基板を曲折させた後に、曲折部の導電パターンを撮影したSEM(Scanning Electron Microscope)画像である。
