【実用新案登録請求の範囲】
凹曲した鏡面の反射面を有し光源の光を所定の 角度範囲内に集める照明器具の反射板において、
前記反射面を放射方向に複数の単位反射面に分 割し、前記各単位反射面の反射光が前記所定の角 度範囲内を各々重なり合つて照明するように前記 各単位反射面を凹曲面または凸曲面で構成したこ とを特徴とする照明器具の反射板。[Claims for Utility Model Registration] In a reflecting plate for a lighting fixture that has a concave mirror reflecting surface and collects light from a light source within a predetermined angular range, the reflecting surface is divided into a plurality of unit reflecting surfaces in the radial direction. and a reflector for a lighting device, characterized in that each of the unit reflective surfaces is configured with a concave curved surface or a convex curved surface so that the reflected light from each of the unit reflective surfaces overlaps and illuminates each of the predetermined angular ranges. .
