Claims (1)
- LEDから出る光を均一に拡散させるためのLEDレンズにおいて、
前記LEDから出る光がレンズの内部に入射する入射面と、前記入射面を通して前記レンズの内部に入射した光を前記レンズの外部に出射させる出射面とを含み、
前記出射面は、
前記LEDの光軸を含む中心領域に形成され、垂直断面上、前記LEDの側に凸な曲面形状を有する第1出射面と、
前記第1出射面を囲む縁領域に形成され、垂直断面上、前記LEDの反対側に凸な曲面形状を有する第2出射面と、
前記第1出射面と前記第2出射面の接続部分に存在し、平面上で前記LEDの光軸を中心とする円形の形態で存在する変曲点と、
前記変曲点の部位に帯状に形成され、垂直断面上、前記LEDの反対側に凸な形状とされ、入射する光を前記変曲点が存在する場合に発生する暗部領域に屈折させて出射させる凸部と、
前記凸部から前記第1出射面の側に所定距離離隔した状態で前記第1出射面の上に形成され、垂直断面上、前記LEDの反対側に凸な形状を有する第1凸部と、
前記凸部から前記第2出射面の側に所定距離離隔した状態で前記第2出射面の上に形成され、垂直断面上、前記LEDの反対側に凸な形状を有する第2凸部と、を含み、
