PROBLEM TO BE SOLVED: To provide a pseudo sunlight radiation device capable of suppressing bending of a diffusion member, even during top-bottom reverse use time.SOLUTION: A pseudo sunlight radiation device 200 comprises: a pseudo sunlight radiation box 6 for storing a light source 22, and adjusting spectrum of light of the light source 22 for acquiring pseudo sunlight; plural pseudo sunlight radiation units 1A-1C respectively having a light emission opening facing a radiation surface of the pseudo sunlight radiation box 6, and emitting the pseudo sunlight from the light emission opening; and a light adjustment member 120 arranging the respective pseudo sunlight radiation units 1A-1C in parallel, traversing between the pseudo sunlight radiation units 1A-1C, and supported to a support body 130 of the pseudo sunlight radiation units 1A-1C. During top-bottom reverse use time, separation of the light adjustment member 120 from the support body 130 due to bending deformation of the light adjustment member 120, is suppressed, by connecting the light adjustment member 120. |
