LED solar simulator for photovoltaic testing
Innovations in Optics' LumiSun-50 multi-wavelength LED solar simulator is designed for terrestrial photovoltaic (PV) testing and research.
Innovations in Optics' LumiSun-50 multi-wavelength LED solar simulator is designed to meet Class AAA solar simulator requirements of IEC 60904-9 for spectral match, uniformity of irradiance, and temporal stability. Primary applications for the LumiSun-50 are terrestrial photovoltaic (PV) testing and research. The LumiSun-50 achieves a spatially uniform illumination field from a chip-on-board (COB), multiple-wavelength LED die array. The field of illumination is 50 x 50 mm at a working distance of 200 mm. The LumiSun-50 includes a driver/controller which individually provides constant current to each die in the COB array. Total irradiance of 1.1 sun units is provided and can be decreased to 0.1 suns. The LED light source of the LumiSun-50 is contained within an air-cooled housing that can rotate the angular beam alignment. Adjustment and setting of the optimum light path working distance is visually facilitated by a converging pair of red dot laser pointers.
