Abstract
【解決手段】LEDチップ2で発生した熱がサブマウント部材4を介してベース部材3に伝わり、さらにベース部材3から絶縁層12を介して本体10に伝導して放熱される。このとき、本体10に設けた凹部11とベース部材3に設けた凸部3aとによってベース部材3と本体10との絶縁層12を介した対向面積が広くなるので、LEDチップ2で発生した熱をベース部材3から本体10へ効率よく伝導して放熱させることができる。
【選択図】 図1
Description
本実施形態の発光装置は、図1に示すように熱の良導体からなる本体10と、本体10表面に電気的な絶縁層12を介して搭載される発光ダイオード1とを備える。
本実施形態の発光装置は、図2に示すように凹部11に代えて本体10に貫通孔13が設けられるとともに、ベース部材3に設けられる凸部3aが貫通孔13に嵌合し且つ凸部3aの先端に放熱フィン3bが設けられた点に特徴がある。但し、その他の構成は実施形態1と共通であるから、共通の構成要素には同一の符号を付して説明を省略する。
