Abstract
【解決手段】実施例は、複数の発光素子が設けられた基板;前記複数の発光素子からの熱を放熱する放熱体;及び前記基板と前記放熱体との間に介在されて前記複数の発光素子からの熱を前記放熱体に伝達して、重量%(wt%)でシリコン10〜30wt%、充填剤70〜90wt%及びガラス繊維2〜7wt%を含むパッドを含む照明装置を提供する。
【選択図】図1
Description
図5は、前記放熱体150の斜視図であり、図6は、図5のA-A’断面を示す断面図である。
図7は、前記発光モジュール基板130及び前記第1保護リング120の結合斜視図であり、図8は、図7のB-B'断面を示す断面図である。
前記発光モジュール基板130は基板132と、前記基板132に搭載される一つまたは複数の発光素子131を含むことができる。
前記基板132上には一つまたは複数の発光素子131が搭載されることができる。一つまたは複数の発光素子131それぞれは少なくとも一つの発光ダイオード(LED:Light Emitting Diode)を含むことができる。前記発光ダイオードは赤色、緑、青色または白色の光をそれぞれ発光する赤色、緑、青色または白色発光ダイオードであることができるが、その種類や数に対して限定しない。
図9は放熱パッド140の構造を説明するための図である。図9aは放熱パッド140の一実施例であり、図9bは放熱パッド140の他の実施例である。
<表2>の場合、15ワット級の場合に放熱パッド140の厚さは1.0Tを超えないことが好ましい。なぜなら、放熱パッド140の厚さが1.0T以上であり、耐電圧特性は良くなるはずであるが、放熱特性が悪くなって、生産費用が頻繁にかかるためである。
下の<表3>は、前記照明装置1が5ワット(W)、8ワット(W)級である場合に放熱パッド140の厚さによる耐電圧特性を示す表であり、<表4>は15ワット(W)級である場合に放熱パッド140の厚さによる耐電圧特性を示す表である。
<表3>の実験は、放熱パッド140のサイズが52パイ(φ)、放熱体150の貫通ホール153のサイズが15(φ)である時の実験である。
図10は、前記ガイド部材100の斜視図であり、図11は、前記ガイド部材100の平面図である。
図4及び図12を参照すると、前記レンズ110は、前記発光モジュール基板130下に形成されて前記発光モジュール基板130から放出される光の配光を調節する。
図16は、前記内部ケース170の斜視図である。
図4を参照すると、前記駆動部160は、前記放熱体150の第1収納溝151に配置されることができる。
前記外部ケース180は、前記内部ケース170と結合されて前記放熱体150、発光モジュール基板130、駆動部160等を収納して、前記照明装置1の外観を成すことができる。
