PROBLEM TO BE SOLVED: To provide a reflection member for forming a polygonal radiation object range.SOLUTION: A reflection member 4 for reflecting an outgoing beam from a light source 2, comprises at least one polygonal cell 40 including: a central bottom part 42 having a polygonal shape in plane view and in which the light source is disposed; inclined parts inclined from the central bottom part toward outer edges. The inclined parts include vertex-part inclined surfaces 46 provided corresponding to respective vertices of the polygon, and side-part inclined surfaces 48 provided between the vertex-part inclined surfaces. In sectional view, an inclination angle α of at least a part of the vertex-part inclined surface is larger than an inclination angle β of the side-part inclined surface.SELECTED DRAWING: Figure 6 |
