Abstract
【解決手段】発光ダイオードのバックライトモジュールである。この発光ダイオードのバックライトモジュールは、金属支持体と、熱伝導性接合材と、回路基板と、発光ダイオードと、を備えている。金属支持体は凹部を有する。熱伝導性接合材はその一方の面で金属支持体の凹部の底面に当接している。回路基板は熱伝導性接合材の他方の面に設けられている。回路基板の突起または弾性留め具が金属支持体の複数の開口溝に係合して、回路基板、熱伝導性接合材および金属支持体を密着接合させる。発光ダイオードは回路基板上に配設されており、この発光ダイオードの熱は回路基板および熱伝導性接合材を介して金属支持体に伝導される。
【選択図】図1
Description
本考案の一実施例における発光ダイオード装置を示す図1を参照する。発光ダイオード装置は、発光ダイオード111と、回路基板109と、金属支持体101とを備えている。発光ダイオード111は回路基板109上に配設されている。回路基板109はプリント基板、金属基板またはセラミック基板とすることができる。金属支持体101はL字状またはU字状とすることができるとともに、凹部115を有する。凹部115は底面101aと二つの側面101bとを有する。二つの側面101bは底面101aに当接しており、この二つの側面の高さは同一または異なっていてもよい。複数の開口溝103が側面101b上に配置されている。
本考案の他の実施例における発光ダイオード装置を示す図6を参照する。金属支持体101は凹部115を有する。熱伝導性接合材105の表面105aが凹部115の底面101aに当接し、熱伝導性接合材105の他方の表面105bが回路基板の表面109aに当接している。発光ダイオード111は回路基板109の他方の表面109bに配設されている。図1と比較して、図6の発光ダイオード装置では弾性留め具601が追加され、しかも回路基板109の縁が面一になっている。
