as a potential next generation solar simulator. This contribution
evaluates the possibilities of generating a light field of appropriate
spectrum with good uniformity. LEDs have very different optical
characteristics compared to standard lights and this needs to
be considered in the optical design. The aim in this paper is to
achieve a close spectral match to the AM1.5 solar spectrum from
350nm to 1300nm. A total irradiance of 1000 W/m2
needs to
be acquired. Additionally, the non-uniformity of light needs to
be equal to or less than 1%. The key to mix spectra and achieve
the desired intensity and uniformity is the optics. This paper
evaluates different optical layouts to assess the potential for fully
LED based solar simulators. The TIRs perform better collecting
more light than other optics tested.
