Abstract
In this paper, the mean-wavelength-based Fresnel lens was designed by merging the
modified edge ray principle and idea of superposition. The
bottom-to-top approach optimizes the design of individual prisms
according to the predetermined plastic optical fiber (POF) bundle
size. The simulated optical efficiency of the collector for the sun’s
visible spectrum (380–740 nm) light is 82.93% with a uniformity
ratio of 0.434. Based on the designed collector, the daylighting
system can deliver 199.38 lumens via a 10 m long POF
bundle with an efficiency of 23.78%. The thermal analysis revealed
that the maximum temperature on the focus plane was 49.7°C.
