SIMULATED SUNLIGHT LIGHT IRRADIATION DEVICE AND INSPECTION DEVICE FOR SOLAR CELL PANEL

摘要

Precise, uniform illuminance is obtained for an irradiation surface without adjustment time of illuminance of the irradiation surface being time-intensive, even for an expansive area. At least one light source (xenon light source 2 or halogen light source 7, or the like) and an optical filter (air mass filter 5, 10, or the like) functioning as an optical element are matched with a respective light guiding member 14 or 14A. Since an irradiation region of the light guiding member 14 or 14A for surface irradiation is directly matched with a respective part of the irradiation surface (small irradiation surface) of an irradiation subject, illuminance on part of the irradiation surface (small irradiation surface) of the irradiation subject can be adjusted with precision by changing the amount of light entering the inside of the light guiding member 14 or 14A for surface irradiation.
