Description
図1は、第1の実施の形態に係る発光装置10の上面図である。図2(a)、(b)は、それぞれ図1の線分A−A、線分B−Bに沿った発光装置10の垂直断面図である。
第2の実施の形態は、発光素子が熱伝導性基板上に直接設置される点において、第1の実施の形態と異なる。なお、第1の実施の形態と同様の点については、説明を省略又は簡略化する。
上記の実施の形態の発光装置10は、発光素子16で発生した熱を熱伝導性基板11の裏面から直下の基板やヒートシンクへ逃がすだけでなく、放熱孔18を通して表面から空気中へ逃がすことができるため、優れた放熱特性を有する。さらに、第2の実施の形態の発光装置20では、発光素子16の周囲の熱伝導性基板11の露出した領域からも効果的に放熱することができる。
