Title:
PSEUDO-SUNLIGHT IRRADIATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/121805
Kind Code:
A1
Abstract:
A pseudo-sunlight irradiating apparatus (18) is provided with optical system sets (100, 101) each of which is comprised of a xenon light source (16) and a halogen light source (17), a light-guiding plate (10), and a prism sheet (11). Transmittance adjustment sheets (12a-12c) are formed on the prism sheet (11). The transmission rate adjustment sheets (12a-12c) has: a characteristic of letting most of the light having a wavelength shorter than a prescribed wavelength be transmitted therethrough, and reflecting most of the light having a wavelength longer than the prescribed wavelength; and/or a characteristic of reflecting most of the light having a wavelength shorter than a prescribed wavelength, and letting most of the light having a wavelength longer than the prescribed wavelength be transmitted therethrough. This enables transmittance of xenon light and transmittance of halogen light to be adjusted independently.
