SIMULATED SOLAR LIGHT IRRADIATION DEVICE AND SIMULATED SOLAR LIGHT IRRADIATION METHOD

摘要

A simulated solar light irradiation device (30) includes (i) a light source section including a first light source (1) and a second light source (2), (ii) light selection means (7) for selecting and emitting (a) light, having shorter-wavelengths than a predetermined boundary wavelength, in first light irradiated by the first light source (1) and (b) light, having longer-wavelengths than the predetermined boundary wavelength, in second light irradiated by the second light source (2), and (iii) control means (5, 6) for controlling a directivity of the first light or a directivity of the second light so that the first light or the second light enters the light selection means (7) at a predetermined incident angle. In this way, it is possible to irradiate designed simulated solar light without increasing a size of the device.
