Description
(第1の実施例)
図3は、本発明に係る照明装置の要部を示す断面概念図である。
図示された表は、(A)は図3に示す構造においてプリント回路基板の表面にAgから形成される反射部材1枚のみを形成した場合の輝度を測定したものであり、(B)は本発明に係る反射ユニットの構造、即ち接着パターン物質をシリコンから形成して図4のパターンを形成し、第1反射部材をAgフィルムとした場合における、従来の(A)構造と比較して輝度向上の結果値を測定したものである。
図7は、本発明に係る照明装置の他の実施例を示すものである。
即ち、上記レジン層140は、上記LED光源130の周りを取り囲む構造で積層され、側方向に出射する光源の光を分散させる機能を実行することになる。即ち、従来の導光板の機能を上記レジン層140で行うようになる。
上述した第2の実施例の構造から改良された構造で上記レジン層上に光の拡散を促進させる光学パターン層が形成される第3の実施例の照明装置の構造を説明する。
本発明に係る照明装置は、光源の数を減らすために、上記LED光源130は側面発光LEDを採用して配置できる。図8を参照すると側面発光型LED130から側方向に光が出射され、出射された光は従来の導光板の代わりに形成されたレジン層140で反射及び拡散され、光学パターン層150により光の集中を防ぎ、拡散板の下部に形成された第3離隔領域により光のばらつきを最小化できる。特に、上記レジン層140とプリント回路基板110との間に配置される本発明に係る反射ユニット120の存在により、反射率をより向上させることができ、光の効率性を極大化し輝度向上の効果を実現することができる。特に、本発明に係る反射ユニット120の場合、接着物質層のパターニングにより離隔領域を形成するデザインを多様に変形して反射率を調節でき、パターニングされた接着物質の材料及び種類に応じて反射率、色の実現を調整できる効果もある。さらに、第2反射部材122の光の特性及び厚さに応じて反射率を調節することもできる。
