Description
本発明の実施形態1の全体構成を図1に示す。本発明の照明器具は、LEDチップのような光源1と、この光源1を搭載した基板2と、光源1からの光を制御する錐状のレンズ3と、それらを収納する筐体4からなる。筐体4の内面と基板2の間の空間は充填材5で充填しても良い。充填材5は透明樹脂などで構成される。光源1の発光部中心と錐状のレンズ3の中心軸は略一致している。
本発明の実施形態2を図2に示す。レンズ3の形状として、前述の実施形態1では円錐形状を例に挙げており、光源1の発光部形状(破線で示す)が円状の場合はレンズ3を円錐状にすると光が均一となる。一方、光源1の発光部形状が図2に示すように四角などの形状の場合は、レンズ3の形状もそれに合わせた相似形状(角錐状など)とすれば、光の水平断面方向の照射パターンはより均一になる。
