Abstract
Description
図2を参照する。本発明に係る第1の実施形態は主回路基板7とお互いに協働するために主回路基板7に取り付けるのに適しているフリップチップ型発光モジュールを提供する。また、フリップチップ型発光モジュールは直接に外部電源と電気接続して、駆動動作されるように使われてもよい。その使用する方式又は分野は本発明の焦点ではないため、ここでは繰り返さない。
I、発光チップ2と放熱基板1との貼り合わせにより、効果的に放熱効果を向上させることができる。かつ、フレーム41における導電経路42を介して、発光チップ2は配線スペースを確保する必要なくパッケージ部品4を通じて外部と電気的に接続することができる。それにより、フリップチップ型発光モジュールの体積を効果的に低減することができて、小型化製品の適用に適している。
図7を参照する。本発明に係る第2の実施形態は大まかに第1の実施形態と同様であり、それらの差異点としては、発光チップ2は2つの頂部導電接触子21及び2つの底部導電接触子22を含み、かつ、それと対応するように、放熱基板1は離隔して配置される複数の板11を含む。隣り合う2つの板11は共に放熱経路12を規定している。
図8を参照する。本発明に係る第3の実施形態は大まかに第1の実施形態と同様であり、それらの差異点としては、レンズユニット44が支持枠441(図2に示すように)を含まず、かつ、レンズ431は直接にフレーム41に配置され、即ち、フレーム41は同時に支持枠441の機能を負担することにある。
図9を参照する。本発明に係る第4の実施形態は大まかに第1の実施形態と同様で、主な差異点としては、支持枠441とフレーム41とは一体成形となるように製造される。
