Abstract
【解決手段】本発明の照明装置は、複数のLED及び電源供給のための接続端子が形成されたLEDモジュールと、前記複数のLEDから発生した光を拡散させる拡散ガイド部と、前記拡散ガイド部が設置され、前記LEDモジュールが結合されるカバーとが備えられる。
【選択図】図1
Description
LEDは、蛍光ランプ方式に比べてインバータが必要ではなく、電流消費が少なく、寿命が長いという長所がある。しかしながら、LEDは、明るさが蛍光ランプより落ちるため、一般照明として使用するには限界がある。
図1に示すように、本発明の実施の形態に係る照明装置200は、複数のLED211及び該LED211に電源を供給するための接続端子216、217とが形成されたLEDモジュール212と、前記LED211から照射された光を拡散させる拡散ガイド部214と、該拡散ガイド部214が挿入されて設置されるカバー215とが備えられて構成される。
