<P>PROBLEM TO BE SOLVED: To provide a pseudo sunlight irradiation device capable of controlling in high accuracy the spectrum of light and irradiating on a solar cell without greatly deteriorating directivity of light. <P>SOLUTION: The pseudo sunlight irradiation device is provided with a light source, a member enhancing directivity of emission light from the light source, a spectrum adjusting member which controls transmittance of emission light from the light source, a light guide member into which light transmitted through the spectrum adjusting member enters, a light extraction means which is arranged in the light guide member and extracts the light entering into the light guide member on an irradiation surface of the light guide member, and a light refractive member which refracts the light emitted from the emission surface of the light guide member in an irradiation direction of light. <P>COPYRIGHT: (C)2013,JPO&INPIT |
