Abstract
A solar illumination design with fluorescent coatings to change in crop growth in vertical farms was investigated using simulations based on numerical analysis. The fluorescent reflectors were used as part of the lighting system to improve the irradiation for photosynthesis over the shelves. The reflectors were based on optical glass (BK7) embedded with fluorescent pigments (K2SiF6:Mn4+) and were used in the light distribution system to increase crop production by improving spatial light distribution and altering the solar spectrum. The optimum number of shelves was identified for three different latitudes, considering a fixed size of solar collector. It was estimated that introducing fluorescent reflectors to the system could lead to an increase in crop production exceeding 35%.
