Minimizing the Lighting Flux of Luminaries for Street Lighting Systems Estimated by Luminance

The present survey presents the results of research about optimization of photometric curves, which purpose is to minimize the needed lighting flux to achieve the standard rates under luminance regarding BDS EN 13201. The geometry and traffic situation which were used to make optimizations are the most frequent occurring in the cities. The optimization is carried on using Matlabfunction for nonlinear minimizing function fmincon. The equations describing the photometric curves use an exponential function which power degree is formed by orthogonal polynomial of Legendre, and the constrain factors are formed on the basis of the methodology for calculation of luminance regarding BDS EN 13201.
