Abstract
【解決手段】本発明により、1つのLED光源毎に反射面を取付けたものを必要間隔で必要数並列に並べると共に、間隔部分を表面に光輝処理をしたエクステンションで覆い、このエクステンションにLED光源からの光中の反射面に達しない部分となるランバーシアン分布Lから光を当接させ、光輝させることで、複数の反射面が一体化して見えるものとして課題を解決する。

Claims (2)
- それぞれがLED光源を有する少なくとも2個の反射面を組合わせ、所定規格の配光特性を得るLEDランプにおいて、前記反射面間にはこの反射面間の間隙を閉塞するように、それぞれの反射面に設けられた前記LED光源からの直射光でかつ前記配光特性を形成するのに有効性が低い部分の光が当接し反射するエクステンションが設けられ、前記LEDランプを略照射範囲から見るときには、前記エクステンション及び該エクステンションが反射する光により前記反射面は一体化した状態として観視されることを特徴とするLEDランプ。
- 前記反射面の前方でかつ下方には第二反射面が設けられており、該第二反射面からの光が前記エクステンションに当接し所定方向に反射するものとされていることを特徴とする請求項1記載のLEDランプ。
