Abstract
【解決手段】ホルダ12は、ホルダ12の一端側の面から見て、基体部23で熱を吸熱可能とする熱容量が放熱フィン22の部分の熱容量より大きい関係を有している。熱容量の大きい基体部23の一端側の領域に複数のLEDチップ43を有する発光部46が位置するように、発光モジュール13をホルダ12に取り付ける。発光モジュール13の複数のLEDチップ43からの熱を、熱容量の大きい基体部23で吸熱する。
【選択図】図1
Description
発光モジュールは、例えば、基板上に複数のLEDチップを実装し、蛍光体を混合した透明樹脂を塗布して封止樹脂層を形成したCOB(Chip On Board)モジュールなどが含まれる。発光部は、例えば、複数のLEDチップおよび封止樹脂層などで構成される。また、発光モジュールの発光部は、基体部の一端側の領域内に位置していることが好ましいが、一部が領域外に位置していてもよい。
