Kind Code:
A1
Abstract:
[Problem] To provide a reflection member for forming a polygonal irradiated region. [Solution] A reflection member for reflecting light emitted from a light source comprises: at least one polygonal cell, the at least one polygonal cell having: a center bottom part which has a polygonal shape in a plan view and in which the light source is disposed; and an inclined part which is inclined from the center bottom part toward the outer edge, wherein the inclined part has: vertex-part inclined surfaces which are provided so as to correspond to the respective vertexes of the polygonal shape; and side-part inclined surfaces which are each provided between the corresponding vertex-part inclined surfaces, and wherein an inclination angle α of at least a part of the vertex-part inclined surfaces is larger than an inclination angle β of the side-part inclined surfaces in a cross-sectional view.
