A rough set-based method for aiming angle tuning of luminaires for outdoor sports lighting

Abstract

When designing outdoor sports lighting it is a challenging task to achieve uniform illuminance over the whole field. Design simulations accomplish this objective by adjusting the aiming angles of the luminaires in horizontal and vertical planes. The lighting design software that is typically used for these calculations does not use any optimization technique. In this paper, rough set theory has been used to find an optimal design for a large scale outdoor sports lighting installation. This modified design process takes the aiming angles of determinant luminaires as the input for the optimization of a total of six lighting parameters. The initial results are very encouraging.
