PROBLEM TO BE SOLVED: To provide an illumination information measurement device capable of easily acquiring accurate illumination information.SOLUTION: The illumination information measurement device includes: a dome-like member 20; a rotation unit 40 for rotating the dome-like member 20 about the rotation axis C passing the dome surface; and measurement units (30, 60, 70, and 80) for measuring the illumination information of illumination light radiated to the dome-like member 20. The dome-like member 20 includes a plurality of lighting holes 21 formed so as to prevent rotation loci by the rotation unit 40 from crossing each other. The measurement units (30, 60, 70, and 80) receive light coming from each of the plurality of lighting holes 21 on a rotation circumferential surface of the dome-like member 20 by the rotation unit 40, and measure the illumination information. |
