Abstract:According to ISO 9847, the indoor calibration of pyranometers is based on the use of light filament sources such metal halide and tungsten lamps that are similar to the sun spectrum. The application of LED light sources is currently promoted worldwide in every field. At NIS, a study on the LED pyranometer calibration system was carried out. The results revealed that, in the absence of a diffuser, the uniformity of the FEL lamp and LED source was 0.76 and 0.89, respectively; however, when a diffuser was used, t… Show more
