PSEUDO-SUNLIGHT IRRADIATION DEVICE AND PSEUDO-SUNLIGHT IRRADIATION METHOD

摘要

PROBLEM TO BE SOLVED: To irradiate pseudo sunlight as designed without enlarging a device.;SOLUTION: A pseudo-sunlight irradiation device 30 includes: a light source part having a first light source 1 and a second light source 2; a light selecting means 7 that selects and outputs light on the shorter-wavelength side than a prescribed boundary wavelength of first light emitted from the first light source 1 and light on the longer-wavelength side than a prescribed boundary wavelength of second light emitted from the second light source 2; and each control means 5, 6 for controlling directivity of the first light or that of the second light so as to allow the first light or the second light to enter the light selecting means 7 at a prescribed incidence angle.;COPYRIGHT: (C)2011,JPO&INPIT
